PREFACE

JLt\tLiJujnL \jitL IN 1955-56 Thor Heyerdahl organized and financed a private expedition to Polynesia. The main objective of the expedition was to initiate modern subsurface archaeology in central and eastern Polynesia, especially Easter Island. Successful attempts were made to study cultural stratigraphy in the archaeological remains on Easter Island, the sequence of masonry techniques, the origin of the statues, and the aberrant forms of masonry structures. Also samples were obtained for C-14 dates, pollen analysis, and blood group analysis. The four senior archaeologists were Mr. Edwin N. Ferdon, Museum of New Mexico; Dr. William Mulloy, Professor of Anthropology, University of Wyoming; Mr. Arne Skjolsvold, Department of Archaeology, Stavanger Museum; and Dr. Carlyle S. Smith, Professor and Curator of Anthropology, University of Kansas. I was not a member of the expedition. At the time I was a colleague of Professor Smith's, who suggested to Mr. Heyerdahl that I analyze the skeletal material from Easter Island. I agreed to do so. Accordingly the material was sent to the University of Kansas for me to study. The conclusions that I have arrived at, based on physical anthropology, and also on the evidence from linguistics, ethnology, and archaeology, apparently do not agree with conclusions reached elsewhere by various members of the expedition, as can be seen at the end of the last section of this study. I am grateful to Dr. Paul N. Arnesen, Department of Orthopedic Surgery, University of Minnesota, for valuable advice in assessing the pathological specimens discussed in Chapter 5, Pathology.

Cranial and Postcranial Skeletal Remains from Easter Island


a statue and yielded nine fragmentary and three complete skulls. Grave 2, found under a statue, contained three complete skulls (Smith, 1961, Fig. 3b). Grave 3 occurred in the platform as a rectangular cist. It contained three complete skulls. Grave 4, found between two fallen statues, had a complete skull. Graves 1-4 also contained various disarticulated unusable posteranial bones. Ahu Vinapu No. 2 is situated on the southern coast east of Rano Kao. All of the skeletal material came from the landward ramp and belongs chronologically to the Late period. The burial custom at this time was apparently to dry the cadavers on stone platforms in the vicinity or on wooden racks and then to break them up and deposit them on the ramp of the ahu either in the open or sometimes in spaces under the fallen statues. They were then covered with stones — usually boulders about a foot or more in diameter. As time went on other bundled cadavers were added by digging holes among the already deposited bundle burials. These were covered with additional stones. The stone pile on the ramp of the ahu was thus gradually added to until in some places it was upwards of five feet deep though in others it was a good deal more shallow. Continual disarrangement of earlier by later burials was the characteristic development so that at the time we excavated the site the picture was one of a pile of stones intermixed with bones on the ramp with no way of separating individual bundle burials. The bones were thus just taken out as we came to them. Most were so badly decomposed that they were useless for measurement and observation. I saved only those that I thought were useful and the others were buried at the site. The numbers on the skulls refer to the locations in the stone pile. . . . My feeling is that the various depths at which they occurred in the stone pile do not reflect any significant time difference that could be proven. I think the pile was established in a rather short time and the possibility of rearrangement of bones after their original deposition was too great to make evidence of this kind of value. Thus the numbers are without time significance. (Mulloy, personal communication, 1957.)

I INTRODUCTION

1 HE skeletal material from Easter Island analyzed in this study was collected in excavations directed by Dr. Carlyle S. Smith of the University of Kansas and Dr. William Mulloy of the University of Wyoming during the Norwegian archaeological expedition to Polynesia in 1955-56. The work done on Easter Island was noteworthy for two main reasons. First, the excavations were conducted in a first-rate scientific manner and second, carbon-14 dates were obtained for the first time on this island. The Sites, Amount of Skeletal Material, and Chronology Ami Tepeu (Fig. 1) is situated on the west coast of Easter Island north of the present village of Hangaroa and west of Rano Aroi. Grave 1, a burial cist, was found in the mantle of loose stones adjacent to the northernmost statue. It contained two skeletons in an extended position (Smith, 1961, PL lib). Grave 2, a burial cist, was found in the loose stone mantle between two of the statues. It contained the remains of eleven individuals in an extended position (see Smith, 1961, PI. Id, Fig. 6). Ahu Hekii is situated on the north coast overlooking Hanga-o-honu (Turtle Bay), a small cove on La Perouse Bay. Graves were found in the platform and sloping mantle. Grave 1 was found adjacent to

The usable material consisted of eleven individuals on the basis of the skulls, or thirteen individuals on the basis of the postcranial remains. The stratigraphy revealed by excavating different kinds of ahu and the various C-14 dates obtained by the expedition indicate three periods which have been dated as follows: The Early period ca. A.D. 400-

the distribution of crania by sex, age and period. The number of females is too small to give significant results. The figures for men indicate that possibly the average age at death was higher for the Late-period males. It is important to know precisely which landmarks were used in different measurements; the measurements used, and the techniques, listed by author, are shown in Appendices A and B. All measurements and morphological observations in this study were done by myself. A few of these measurements need further explanation. With the exception of the measurement of infra-temporal fossa depth, all are of my own devising. Temporal Muscle Width. Measured parallel to the zygomatic arch, from the point where the sphenozygomatic suture meets the fronto-zygomatic suture to

1100, the Middle period ca. A.D. 1100-1680, and the Late period A.D. 1680-1868 (Smith, 1961, Vol. I, pp. 210-212, 393-396). Table 1 shows the chronology of the usable skeletal material by sex. None of the material is earlier than the Middle period, and most is from the Late period. I do not attribute any particular significance to the difference in numbers between the sexes or the fact that only one intact child's calvarium was obtained, since females' and especially children's, skeletal remains are fragile and less likely to survive. Methods The ages of all the crania in this study were assessed on the basis of endocranial suture closure even though this technique has been criticized (Singer, 1953; McKern and Stewart, 1957).

the extension superiorly of the supramastoid crest onto the parietal bone. Temporal Muscle Height. Measured perpendicular to temporal muscle width from the upper border of the zygomatic arch directly above the tuberculum articulare to the inferior temporal line. Infra-temporal Fossa Depth. Measured from the upper border of the zygomatic arch horizontally to the deepest point in the fossa on the greater wing of the sphenoid bone (Keen, 1951). Malar Height. Measured from zygomaxillare to the most inferior point of the left orbit. Malar Width. Measured from frontomalare temporale to the most inferior point of the left orbit. Malar Area. Equals malar height multiplied by malar width. Forehead Height. When on the median sagittal craniogram tracing a line is drawn through glabella parallel to the Frankfort Horizontal, and a perpendicular line is drawn from this glabella line to the top of the frontal perpendicular, the resulting perpendicular line is the forehead height.

Frontal Slope Angle. When a line is drawn joining the glabella and the top of the frontal perpendicular and then when from the latter a perpendicular line is dropped to the Frankfort Horizontal, the angle formed between these two lines is the frontal slope angle. The Cranial Capacity Technique. Based upon a waterproofed test skull (Tildesley, 1948). The test skull gave a cranial capacity of 1385 cc with water. On five consecutive days the cranial capacity of the test skull was obtained with mustard seed. The mustard seed was not tamped down. The average of these readings was 1432 cc. The cranial capacity recorded in subsequent tables, therefore, was obtained from the formula 1385/1432 X cranial capacity obtained with the mustard seed. This calculated cranial capacity was felt to be a more accurate indication of the actual cranial capacity. Mean Height Index. The mean height index is the basion-bregma height X 100/mean of the maximum length plus the maximum width (Stewart, 1942).

minority of the means differ by more than two standard deviations from the means of the grouped males. This evidence too favors the theory of a biological homogeneity or racial continuity from the Middle to the Late period. The metrical observations for the grouped males indicate the following: Cranial index. The cranial index of 70.82 falls into the long-headed category. Height of vault. The height-length index of 75.51 based on basion-bregma height is hypsicranial or high-vaulted. Similarly the auricular height ( vertex) length index of 65.00 is acrocranial or high-vaulted. The latter index is the better of the two because as Rogers (1954) has pointed out the auricular height is a valuable but often neglected measure. It is a better indicator of vault height than the basionbregma or the basion-vertex heights because it is more independent of fluctuating influences on the basilar part of the occipital bone, which in turn determines the relative position of basion. The fronto-parietal index is eurymetopic or a broad minimum frontal compared to the maximum width. Orbital Shape. The mean orbital index of 90.44 shows a hypsiconch or high orbit. Nose. The nasal index of 52.30 is chamaerrhine or wide. Facial Height. The total facial index of 85.87 is on the border of meso-to-euryprosopic or a medium to wide face compared to its length. This is doubtless a reflection of the "rocker" type mandible which will be described later. The upper facial index of 51.74 is on the border of mesene and euryene or a medium to wide face. Palate Shape. The external palatal index (maxilloalveolar) of 120.50 is brachyuranic or broad. The internal palatal index (palatal) of 80.68 is on the border of lepto- and mesostaphyline or medium to long, which indicates that the alveolar processes are relatively thick. Prognathism. The gnathic index of 95.10 is orthognathic as is the facial profile angle of 87.33°. The latter is the better indicator of prognathism since it is less, affected by any bending upward of the basilar part of the occipital bone (Rogers, 1954). The nasal profile angle is orthognathic and the alveolar profile angle is hyperorthognathic.

II METRICAL AND MORPHOLOGICAL OBSERVATIONS OF THE CRANIA

INDIVIDUAL measurements and indices, median sagittal craniogram measurements and indices, and angles by sex are shown in Tables 3A to 3D for the Middle period and Tables 4A to 4D for the Late period. I hereby make a plea that other Polynesian researchers publish individual measurements for eventual useful comparisons. The ranges and means for the Middle period are shown in Tables 5A to 5D and for the Late period in Tables 6A to 6D. Clearly the number of females is too small to allow significant results; therefore only the males will be used for this purpose. If one compares the male Middle period means with those of the Late period in Tables 3A-6D, it is obvious that they are remarkably alike. In my opinion, the males of the Middle and Late periods were products of the same gene pool. For this reason all the males were grouped together for a dispersion analysis of the cranial measurements, which are shown in Tables 7, 8, 9, and 10. If one compares the means of the measures of the Middle and Late period males with those of the males grouped together, it is quite clear that only a 7

Foramen Magnum. This is of medium shape with an index of 84.40. Cranial Capacity. The cranial capacity figure of 1449.31 cc shown in Table 7 was based on a correction factor as described under Methods. Since some may object to this technique, the average was worked out for the cranial capacity obtained without using the correction factor. The results are 1498.44

cc ± 27.83; a= 111.33 ± 19.70 and the coefficient of variation = 7.43 ± 1.32. As a matter of interest the average cranial capacity based on the Lee Pearson "interracial" formula using auricular height (359.34 + 0.000365 X L X B X H) gives the figure 1490.69 cc, which is close to the average of 1498.44 cc. The cranial mode average of 1548.76 cc shows it is not an accurate indicator of cranial capacity.

Mandible. This is best described under morphologyThe individual morphological observations are shown in Tables 11 and 12. FORM

The grouped males in Table 13 show mostly a pentagonid or ovoid shape in the norma verticalis and a characteristic haus-form shape in the norma occipitalis. FRONTAL REGION

Supraorbital Type. The supraorbital type is based on De Young's (1941) definitions for comparative purposes (Fig. 2). 1. The supraorbital ridges are confined to the region above the median halves of the orbits and are clear of the supraorbital margin. IB. Same as 1, but glabella is level with the supraorbital bulges, 1C. Distinct glabella thickening which extends toward the median angle of each orbit yet does not possess the kidney-bean shape of 1. 2. Median brow ridges are developed and also the external halves of the supraorbital margins, but not the supraorbital trigonum. 2B. Same as 2, but glabella is level with the supraorbital bulges. 2-3. Glabella generally has a slight depression between pronounced supraorbital bulges, which have spread to the supraorbital trigonum but not producing a continuous torus. 3. Continuous brow ridge from glabella to external angular process to produce a supraorbital torus. Most of the males fall into categories 1 or IB. However, it should be noted that 15.8 per cent fall into categories 2-3 and 3. Supraorbital Size. Most of the crania show a slight to medium development. Foramina Supraorbitale. Present in 68.4 per cent. Foramina Frontale. Present in 36.8 per cent. Glabella Type. This is based on the modified Broca scale (Martin, 1928, p. 873) which is also useful for comparative purposes (PI. 1, top). Most of the crania fall into category III, but categories V and VI - large to very large-each have 15.8 per cent. Frontal Bosses. These are mostly small.

Figure 2. SUPRAORBITAL TYPE, BASED ON DE YOUNG'S (1941) DEFINITIONS

Metopism. 11.1 per cent of the males exhibit this feature (PI. 1, lower left). Supranasal Suture (N). The persistence of the supranasal portion of the medio-frontal suture occurs in 38.9 per cent of the males (PI. 1, lower right).

Supramastoid Crest Size. The majority show a medium to large size. Pterion Type-Left ft or Right (Murphy, 1956). Mostly sphenoparietal.

PARIETAL REGION

Lambdoid Flattening. The majority show a slight to medium flattening. Inion Size. 61.9 per cent have a small to medium size. Occipital Torus Size. Mostly small to medium in size. Occipital Torus Shape. Almost evenly distributed between ridge or mound shape. Occipital Ruggedness. The nuchal area is mainly of a medium ruggedness.

Sagittal Elevation. There is a characteristic medium to marked elevation. Postcoronal Depression. Slight to distinct in 65 per cent of the males.

Parietal Bosses. Mostly medium. Parietal Notch Bone. Completely absent. TEMPORAL REGION

Mastoid Size. 42.9 per cent are large.

Plate 2. "ROCKER" MANDIBLES.

"Rocker"-Type Mandible. "In such a mandible the inferior margin of the mandibular body is convex downward. As a result, the bone may teeter like a rocking chair if placed on a table top and depressed and released either on the chin or the top of the ramus." (Marshall and Snow, 1956b, p. 414.) This characteristic Polynesian feature is present in 35.3 per cent of the Easter Island males (PI. 2). Craniostat Drawings Three views were drawn: norma lateralis, norma facialis, and norma verticalis on a modified Western Reserve Craniostat. Two skulls of each sex were selected to show the opposite ends of the range of measurements, thus giving an indication of the amount of variation within this physical type. Figure 3b and Plate 3 represent a male individual. The skull is hyperdolicocranic with a cranial index of 67.8. The auricular height (vertex)-length index is 64.3 or hypsicranial. Norma lateralis shows little prognathism. The supraorbital type is II-III and the size is marked. Inion size is large. Nasion depression is marked and the nasal profile is concavo-convex. The malars are large. Norma facialis shows a wide upper face with a slight orbital inclination. The nose is mesorrhine with an index of 50.0. Norma verticalis indicates a long ovoid shape with the zygomatic arches projecting laterally to the cranial contour. Figure 3a and Plate 4 represent another male. The skull is on the border of meso- and dolicocrany with a cranial index of 75.0. The auricular height (vertex)-length index is 69.0, very hypsicranial. Norma lateralis shows little if any prognathism. The supraorbital type is IB and the size is slight. Inion size is medium. Nasion depression is slight and the nasal profile is concave. The malars are large. Norma facialis indicates a wide upper face with a slight orbital inclination. The nose is chamaerrhine with an index of 56.8. Norma verticalis shows a pentagonid shape. Figure 3d and Plate 5 represent a female. The skull is hyperdolicocranic with a cranial index of 68.1. The auricular height (vertex)-length index is 66.5 or hypsicranial.

malars are of medium size. Norma facialis shows a wide face, with a medium orbital inclination. The nose is chamaerrhine with an index of 60.4. Norma verticalis indicates a long ovoid shape with the zygomatic arches projecting laterally to the cranial contour. Figure 3c and Plate 6 represent another female. The skull is mesocranial with a cranial index of 76.9. The auricular height (vertex)-length index is 68.2 or very hypsicranial. Norma lateralis indicates con-

siderable alveolar prognathism. The supraorbital type, size, and inion are absent. Nasion depression is absent and the nasal profile is concave. The malars are medium in size. Norma facialis shows a wide face even though the left zygomatic arch is broken. There is a medium orbital inclination. The nose is chamaerrhine with an index of 54.5. Norma verticalis shows a pentagonid shape. So few teeth were present that no attempt was made to analyze them.

The metrical and morphological observations for the grouped males (unless otherwise stated) show the following: Clavicle. This is of short to medium length, the left clavicle, 140.0 mm, being a little longer than the right, 138.6 mm. Both left and right clavicles are mostly slender in size and have a medium curvature. Scapula. The scapular index of 65.5 indicates a scapula of narrow to medium width (morphological length) compared to length (morphological width). The vertebral border is mainly convex. The scapular notch is medium to deep, and the teres process is slight. The clavicle width of 138.6-140.0 mm and the scapular width of 98.0 mm indicate shoulders which were probably not broad. Humerus. The length, 318.7 mm (L) and 317.8 mm (R) torsion angle, 155.2° (L) and 151.3° (R), and bi-epicondylar width, 57.8 mm (L) and 58.1 mm (R) are all medium, as was the general robusticity. Radius and Ulna. Both are of medium length, radius 246.2 mm (L) and 246.4 mm (R), ulna 266.0 mm (L) and 262.0 mm (R), and of medium robusticity. Radio-humeral Index. The one male index (No. 2) of 77.5 falls into the mesati-kerkic group, thus the radius is of medium length compared to the humerus length. Hand. The male skeleton (No. 2) from Ahu Tepeu, Grave 1 had most of the bones of the hand present with the exception of the carpus, which allows one to make some estimate of the proportions of the hand. The right hand index (base width of metacarpals II-IV X 100/length of metacarpal III-(-phalanx 1 + 2 + 3) is 32.9, or a narrow to medium width compared to the length of the hand. The right palmar index (base width of metacarpals II-IV X 100/length of metacarpal III) is 79.7, which is mesocheiric, that is to say neither narrow nor wide. The right digital index (length of metacarpal III X 100/length of phalanx 1+2 + 3 of digit III) is 70.4, indicating a medium length of the palm compared with that of the free fingers. The robusticity index of the right metacarpals, II-V: 36.2, 36.2, 31.1, 33.3, indicates rather slender metacarpals. The same is true of all the other male metacarpals (numbers 69, 70, 72, 74, 76, 77, 78). The right thumb index (total length of thumb X 100/

Ill METRICAL AND MORPHOLOGICAL OBSERVATIONS OF THE POSTCRANIA

JLU B L I S H E D datable postcranial skeletal material from Polynesia is rare; I therefore again plead that individual postcranial measurements be published for comparative purposes. The individual postcranial measurements, indices, and observations by sex are shown in Table 14 for the Middle period and in Table 15 for the Late period. There are more bones from the Late period; however, the total remains are not numerous. The ranges and means for the Middle period are shown in Table 16, for the Late period in Table 17. In general the male remains are more numerous. The males were again grouped together for dispersion analysis; the results are shown in Table 18. If one compares the means of the measures of the Middle and Late period males with those of the males grouped together, in only one case —that of the maximum diameter of the head of the right humerus —do the means differ by more than two standard deviations from the means of the grouped males. Thus the postcranial remains also favor the existence of a racial continuity from the Middle to Late period. 33

CRANIAL AND POSTCRANIAL SKELETAL REMAINS FROM EASTER ISLAND axis (McCown and Keith, 1939, p. 103) the total is 464.0 mm. "In the living spine about three-fourths of the height is formed by the bony bodies and the remaining fourth by the invertebral discs" (McCown and Keith, 1939, p. 103). Thus to obtain the actual height of the pre-sacral column one must add here 154.6 mm to give a living height of 618.6 mm. "The average pre-sacral height in European males is about 619 mm" (McCown and Keith, 1939, p. 103). In Europeans the cervical region usually forms 15.3 per cent of the combined heights of the vertebral bodies (excluding the atlas and axis), the thoracic region 53.4, and the lumbar 31.3 per cent (Martin, 1928, p. 1079). Using 429.0 mm as the combined heights of the vertebral bodies and 64.0 mm, 237.0 mm, and 127.0 mm as the cervical, thoracic, and lumbar heights as above, the percentages are 14.9, 55.2, and 29.6, indicating slightly shorter cervical and lumbar regions compared with Europeans. The relative proportions of the lumbar vertebrae can be shown in the following manner. One can combine the two body heights to get a mean body height and also the width and dorso-ventral (superior and inferior sagittal) measurements. Then one can combine the measurements of all the vertebrae to give an ideal lumbar vertebra. This was done for vertebrae lumbar 1 to 5 of numbers 64 and 128. The width of the mean lumbar vertebra is 47.6 mm, the height is 26.0 mm and the dorso-ventral measurement is 34.2 mm. Thus the height is 54.6 per cent of the width and the dorso-ventral diameter is 71.8 per cent of the width. The average lumbar index for vertebrae lumbar 1 to 5 of numbers 64 and 128 is as follows: lumbar 1-114.5, 2-110.5, 3-106.0, 4-104.1, and 5-88.7. The average total lumbar index is 104.4, showing presumably little or no anterior convexity, but it must be remembered that much of the lumbar curvature is determined by the shape of the intervertebral discs and tension of the intervertebral ligaments. The morphological observations on the vertebral column are shown in Tables 14 and 15. Pelvis. The average innominate heights of 213.2 (L) and 207.2 (R), and widths of 152.5 (L) and 150.4 (R), are not absolutely large, the width in fact being somewhat narrow. The innominate indices

49

thus are 71.1 (L) and 72.6 (R). Sacro-sciatic notches average 28.0 mm X 42.0 mm (L) and 28.0 mm X 43.0 mm (R), with posterior segment 11.0 mm (L) and 13.0mm (R), using the Letterman (1941) technique. These are definitely male proportions. In skeleton No. 2 the left innominate height X 100/left femoral length is 47.0 or a medium innominate height compared with the femoral length. In No. 15 the estimated bi-iliac width is 265.0 mm which is small; the innominate height X 100/bi-iliac width (estimated) is 76.6; and the estimated pelvic inlet index is 92.9 or mesatipellic. The average of the two estimated female pelvic inlet indices (numbers 28 and 29) is 82.3 or platypellic. Morphological observations indicate for the males absent to slight pre-auricular sulci, a medium sub-pubic arch and converging ischia. The pubic symphysis phase is mainly in the 42-50 year age range. The average sacrum height, 121.7 mm, and width, 110.2 mm, are fairly large absolute figures, giving a sacral index of 90.85 or dolicohieric. Morphological observations show for the males a predominant slight curvature, 5 or 6 sacral segments, and a hypobasal type. In general the male pelves showed a medium over-all robusticity. Femur. The maximum length figures for the males are 452.1 mm (L) and 446.2 mm (R). The maximum head diameters are 45.8 mm (L) and 44.4 mm (R). The torsion angle figures are 25.4° (L) and 28.2° (R), which are fairly high. The platymeric indices are 71.3 (L) and 72.7 (R), exhibiting very little transverse thickening in the upper shaft. The pilastric indices of 114.0 (L) and 115.8 (R) show a fair degree of pilastering of the linea aspera. The average of the index bicondylar width X 100/maximum length of the femur gives the figure 18.6 (L) and 17.4 (R). Thus the distal end of the femur is of moderate width compared with its length. The robusticity indices are 12.3 (L) and 12.0 (R), which indicate a medium robusticity. Morphological observations indicate predominantly a slight to medium development of the crista hypotrochanterica, an absent third trochanter, and a slight to medium bowing of the femoral shaft. The right patella shows a fair average height of 44.0 mm, width of 44.0 mm, thickness of 21.0 mm, and height-width index of 100.1. Tibia. The maximum length figures are 376.1 mm

50


(L) and 373.4 mm (R), which are greater than the mean length of 365.0 mm for modern European males (Martin, 1928). The platycnemic indices are 71.8 (L) and 75.2 (R), indicating a relatively low degree of medio-lateral flatness of the shaft or eurycnemia. Concerning platycnemia McCown and Keith (1939, p. 47) state that It is produced by the formation of a bony pilastre formed on the hinder aspect of the shaft and laid down between the medial margin of the shaft and the interosseous border. It leads to an increase of the antero-posterior diameter . . . the tibial pilastre is formed between the areas which give origin to tibialis posterior (laterally) and the flexor digitorum longus (medially). Although we can offer an anatomical explanation of the tibial pilastre (and platycnemia) we are still at a loss to explain its functional utility. A medium head retroversion is indicated in the average retroversion angle figures of 12.2° (L) and 11.6° (R). Skeleton No. 2 shows tibial-femoral indices of 88.2 (L) and 87.9 (R); thus the tibia is relatively long compared with the femur. Morphological observations indicate that the external condyle is either flat or has a slight convexity and the squatting facets are predominantly medium in development. Fibula. The maximum length mean for three left male fibulae is 377.6 mm. These fibulae were all deeply fluted. Foot as a Whole. It is not often that one has enough foot bones to reconstruct the foot. However, this was possible to a large extent in the case of female skeleton No. 1, and male skeleton No. 2, both from Ahu Tepeu, Grave 1 (see PI. 7). In Table 15 under Reconstructed Foot it can be seen that the male (left) tarso-metatarsal II length is 211.0 mm and for the female (right) 168.0 mm. The left male proximal phalanx (II) length is 31.0 mm. I have estimated the middle and distal phalangeal (II) lengths to be 26.0 mm, thus giving a phalanges of digit II length of 57.0 mm for the male. For the female I estimated a length of 52.0 mm. Therefore, the estimated male total foot length is 268.0 mm and for the female 220.0 mm. Now the male tarsus width is 62.0 mm and the female 55.0 mm. Thus the length-width index is 23.1 for the male and 25.0 for the female, suggesting relatively narrow

feet for their length. The estimated absolute total length of 268.0 mm for the male is a surprisingly large figure considering the relative general shortness of his other long bones.

CRANIAL AND POSTCRANIAL SKELETAL REMAINS FROM EASTER ISLAND The tarsal length of the male is 126.0 mm, that of the female 101.0 mm. Hence the tarsus-total fool length index is 47.0 for the male and 45.9 for the female. The phalanges of digit II-total foot length index gives a male index of 21.3 and female 23.6. For the female the tarso-metatarsal I to tarso-metatarsal II length index is 98.8. The tarso-metatarsal IV to tarso-metatarsal II length index for the male is 91.0 and the female 93.5. The tarso-metatarsal V to tarso-metatarsal II length index is 82.9 for the male and 85.7 for the female. In this case, then, the degeneration in length of the fourth and fifth digits is greater in the male. Talus. The four male right tali show the following averages. The length-width index is 79.2, the lengthheight index is 58.7. Martin (1928) gives corresponding figures of 82.7 (sex?) and 60.8 (sex?) for Maori. The angle of the neck to the body is 29.0°, a much higher figure than the mean angle of 17.8 (sex?) given by Martin for Europeans. The angle of the head with the horizontal plane is 33.3° whereas in modern Europeans the mean is 40° (Martin, 1928). Head + neck to total length index is 38.4 Calcaneus. The means of five male right calcanei are as follows. The absolute length of 78.4 mm and width of 40.4 mm are medium dimensions, giving a middle width-length index of 54.1. However, the least width-length index is 28.6, which is lower than the mean of 35.7 (sex?) for Europeans given by Martin (1928). Thus the Easter Island calcanei are apparently narrow for their length. The height-length index is 53.7. The heel to total length index is 47. thus the heel is long. Os Naviculare. Dimensions of the male (No. 2) os naviculare are medium with the exception of the antero-posterior diameter of the tuberosity, 18.0 mm (L), 19.0 mm (R), and the thickness of the facet

51

for cuneiform III, 14.0 mm (L and R), which are large. Cuboid. All the dimensions of the male left (No. 2) and right (No. 86) cuboid are medium in size; the upper medial length 33.0 mm (L) and 31.0 mm (R), the lateral border length 17.0 (L) and 15.0 mm (R), and the length of lateral border to upper medial border index is 51.5 (L) and 48.4 (R). Cuneiform Bones. Worth mentioning here are the rather low figures for the width-height index of the distal articulation for cuneiform I (R) of No. 2 which is 43.8, and the same index for cuneiform III, 68.2 (L) and 58.3 (R). Metatarsal Bones. The male mean absolute length of metatarsal I is 66.0 mm (L) and 67.0 mm (R). These figures exceed the mean 60.2 mm given for Europeans by Martin (1928). The length-width index is 21.2 (L) and 20.9 (R), indicating narrow widths compared with lengths. If one designated the mid-shaft width -f mid-shaft height X 100/maximum length as a robusticity index, the figures are 40.9 (L) and 40.3 (R). The mean male maximum length for metatarsals II-V are as follows: II-78.0 mm (L), 82.0 mm (R); III-73.0 mm (L), 73.0 mm (R); IV-74.0 mm (L), 74.0 mm (R); V-73.0 mm (L), 70.0 mm (R). All of these are larger than means given for Europeans by Martin (1928). Using the length of metatarsal III as 100.0, the lengths of the other metatarsals can be expressed as percentages of the length of metatarsal III. These percentages are 90.4 (L) and 91.8 (R) for metatarsal I, 106.8 (L) and 112.3 (R) for metatarsal II, 101.4 (L and R) for metatarsal IV, and 100.0 (L) and 95.9 (R) for metatarsal V. These figures indicate, though we must keep in mind the small numbers involved, a long metatarsal IV compared with III. The metatarsal V measurements of maximum length included the tuberosity.

skeletonization of American casualties of the Korean war. In this study equations were devised suitable for White, Negro, "Mongoloid," and Mexican males. Certain statements regarding stature estimation made by various authors are very pertinent and worth reproducing here. Telkka (1950, p. 105) stated that In 1928 Martin gave the ratios of the lengths of the limbs and the whole stature of different peoples: The relative length of the upper limbs of males (in percentage of the whole stature) varies from 43.1 to 48.3, and that of the lower limbs from 46.2 to 52.7. When examining these ratios one cannot avoid noticing that the ethnical variations are so perceptible as to make the tables which are based on one race in many cases inapplicable to another race, without having to allow for the error caused by this ethnical variation alone.

IV THE ESTIMATION OF STATURE

Trotter and Gleser (1952) have the following criticisms to make. Regarding Pearson's use of Rollet's data, Pearson's sample was composed almost entirely of middle-aged or old individuals averaging about sixty years. On the basis of his equations stature for a young adult population such as, for example, French military males would be estimated almost 2 cm too short due to the aging factor alone. (P. 502.) Telkka's equations suffer from . . . the smallness of the sample, the possible sampling bias in cadaver material, the transformation of cadaver measurements to living stature and the uncontrolled age factor. . . . Dupertuis and Hadden utilized reasonably large samples each with an adequate range of stature excepting the White males. But their samples were drawn from the lower socio-economic level, no allowance was made for change in stature from aging, and it was assumed that Todd's measurements of cadaver stature represent living stature. . . . In applying formulae derived from data of a particular group to bone measurements from another population the possibility of differences in the relationship between bone length and stature for the two populations must be recognized. (P. 503.)

1 H E whole question of estimating stature must be approached with some caution. As late as 1950, Telkka (1950, p. 104) stated that "In 1888 Rollet published his paper 'La Mensuration des os longs des membres,' which has become classical in this field. The tables compiled later on and based on his measurements are perhaps the ones most frequently used even today." The tables referred to here are the later work of Manouvrier (1893) and Pearson (1898). In 1950 Telkka devised regression equations for estimating stature, based on skeletons from the collections of the Department of Anatomy, Helsinki University. In 1951 Dupertuis and Hadden published regression equations based on White and Negro, male and female skeletons from macerated cadavers whose heights had previously been measured. The material was from the Western Reserve University School of Medicine. These authors assumed that their cadaveric stature was equivalent to living stature. In 1952 Trotter and Gleser published regression equations based on the comparison of lengths of long bones with the known living stature of male American military subjects, White and Negro, from World War II. These authors also included in this report regression equations based on White and Negro, male and female skeletons from the Terry Anatomical Collection, Washington University. In 1958 the same authors reported regression equations based on male measurements of stature during life and bones after

This statement supports Telkka's statement above. Trotter and Gleser (1958, p. 119). "Do not combine formulae obtained by different investigators, based on different races or populations in different geographical areas, nor pertinent to different generations. . . . Do not estimate stature by determining the average of estimates obtained from several equations, each of which is based on a different bone or 52


on a combination of bones." But doing either the first or the second does not reduce the error of estimate. They also state (1958, p. 119) that "In all studies of bone length-stature relationship the lower limb bones have been shown to have lengths which are correlated more highly with stature than have the upper limb bones. Therefore, it can be stated as a general rule that in no case should length of upper limb bones be used in the estimation of stature unless no lower limb bone is available." In the Easter Island sample Ahu Tepeu Grave 2 yielded the skeletons of a male and a female. However, for the rest of the sample it is not possible to say which long bones went with a particular skull. For this reason and because of Trotter and Gleser's statement quoted just above I decided to use only the femur in the estimation of stature. The results are shown in Table 19. Though Pearson used long bone lengths of the right side, I have used his formulae for both left and right femur in this sample. Telkka's corrections for left and right femur were used in his formulae, but 2 cm was not subtracted from each estimation. The same was done in using the Dupertuis and Hadden formulae. Trotter and Gleser (1952, p. 476) believe it is not necessary "to make an adjustment when only one bone of a pair is available for stature estimation." Since Trotter and Gleser make allowance for the age factor, the same was attempted in the Easter Island sample as follows. The two skeletons from Ahu Tepeu Grave 2 are in Trotter and Gleser's age category of 18-30; hence no adjustment for age is necessary here. The rest of the crania, with which the remaining long bones were associated, were then used to work out an average age. This was done by taking the midpoint of each age category (see Table 2), multiplying by the number of crania falling into this category, adding these results, and working out an average as follows. For the males age 28 X 3 = 84, age 45 X 5 = 225, age 65 X 3 = 195; 504/11 = 45.8 years. For the females age 28 X 1 = 28, age 4 5 X 3 = 135; 163/4 = 40.8 years. Trotter and Gleser (1952) state that to estimate stature of individuals older than 18-30 years of age, subtract .06 (age in years — 30) cm. Therefore, the correction factor here for the males is .06 (45.8 — 30) = 0.94 cm, for the females 0.6 (40.8 — 30) = 0.64 cm.

c

It must be emphasized that in this sample the number of femora used is small. For the males, left or right, the number is 11. For the females, left 8, right 5. Thus, any interpretation of stature estimation in this case should be a cautious one. Nevertheless the results are interesting. For the males, the estimated mean stature, using the Pearson formula, is 166.3 cm (L) and 165.2 cm (R); by the Telkka formula 168.6 cm (L) and 167.6 cm (R). If one subtracts 2 cm as Telkka suggests to arrive at living stature the results are 166.6 cm (L) and 165.6 cm (R), almost identical with the Pearson results. The Dupertuis and Hadden formula gives 172.7 cm (L) and 171.5 cm (R). The Trotter and Gleser White formula gives 169.6 cm (L) and 168.2 cm (R), their Negro formula 166.3 cm (L) and 165.1 cm (R), again almost identical with the Pearson formula. Using the Pearson formula, the results for females are 151.6 cm (L) and 150.6 cm (R). The Telkka formula gives 154.3 cm (L) and 153.5 cm (R), or, subtracting 2 cm, 152.3 cm (L) and 151.5 cm (R). The Dupertuis and Hadden formula gives 156.9 cm (L) and 155.8 cm (R). The Trotter and Gleser White formula gives 153.6 cm (L) and 152.4 cm (R), their Negro formula 151.6 cm (L) and 150.4 cm (R), almost identical with the Pearson formula. It is interesting here to note that Roggeveen (1908, p. 15) described Easter Islanders in 1722 as "big in stature." G. A. Forster (1777, p. 564) writing of his March, 1774, visit to Easter Island and concerning only a hundred or a hundred and fifty natives who assembled when he landed, says: "They were inferior in stature to the natives of the Society and Friendly Isles, and to those of New Zealand, there being not a single person amongst them, who might be reckoned tall." Of some ten or twelve women in the crowd he says that they "were very small and slender limbed . . . " Beechey (1832, p. 51) states, "our estimate of the average height of the people [presumably males] was 5 feet 7% inches" (or 171.5 cm). Now which mean estimate is likely to be the most correct? Bormida (1951b), in his study of the mean

living stature of adult "pure" Easter Islanders, gives the figure 172.4 cm (N=17) and 161.0 cm for females (N=18). Trotter and Gleser's (1958) male formulae were based on American Whites with a mean living stature of 173.95 cm and American Negroes with 173.43 cm. The mean White female cadaver stature was 160.68 cm, and the Negro 160.89 cm. The Dupertuis and Hadden formulae were based on American Whites with a mean cadaver stature of 172.96 cm (male) and 160.96 cm (female). Telkka's formulae are based on Finns with a mean cadaver stature of 169.4 cm (male) and 156.8 cm (female). Pearson's formulae are based on French cadavers with a corrected mean stature of 165.0 cm (male) and 152.3 cm (female). However, both Telkka and Trotter and Gleser, as stated above, have pointed out that the relation between leg length and stature is also important. The ratio of sitting height to stature of World War I troops gives 52.6 for American Whites and 50.8 for American Negroes (Herskovits, 1930). Bormida gives 51.9 for Easter Island males and 53.6 for the females. It would thus appear that in applying available formulae to the Easter Island sample the White formulae would be more accurate. Of the White male formulae in Table 19 it is my opinion that the Pearson and Telkka formulae, applied to the present Easter Island sample, give mean stature estimates that are too low. The correct mean stature estimate then, may lie between the 169.6 cm (L) and 168.2 cm (R) derived from the Trotter and Gleser formula and the 172.7 cm (L) and 171.5 cm (R) derived from Dupertuis and Hadden. The same can be said for the females, 153.6 cm (L) and 152.4 (R) derived from the Trotter and Gleser formula and 156.9 cm (L) and 155.8 cm (R) derived from the Dupertuis and Hadden formula. The latter estimated mean statures are considerably lower than the 161.0 cm of Bormida's living Easter Island females. The reason for this could be that the small size of the female femoral sample in my study caused a nonrepresentative result.

Thoracic and Lumbar Vertebrae, Adult Female. The twelfth thoracic and first lumbar vertebrae show anterior bilateral medium-sized bony osteophytes arising from the superior border of the body. The second lumbar vertebra has a unilateral (right) similar osteophyte arising from the superior border. The third lumbar vertebra has a similar osteophyte, unilateral (left), arising from the inferior border. Fourth Lumbar Vertebra, Adult Female. Small anterior unilateral osteophyte arising from the superior border of the body. Lumbar Vertebrae, Adult Female. Third lumbar vertebra has a medium sized unilateral (right) osteophyte arising from the inferior border of the body. The fourth lumbar vertebra has bilateral (right side large) osteophytes arising from the superior border of the body (PI. 8, middle right); 5-7 represent osteophytosis of the spine, spondylitis deformans (Benecke), or spondylosis deformans (Schmorl). Adult Right Fibula, Male. The shaft at about a third up from its lower end shows a marked bowing, which may have been caused by rickets (PI. 8, top right). However, Scott (1893) in his study of the Maori skeletons mentions the curved shaft of the fibula and says it may be due to a squatting posture. None of the crania and mandibles examined showed any evidence of alveolar abscesses. It will be observed that four or five of the above specimens are arthritic. Probably the total sample number of individuals of both sexes represented by various bones is forty-three. Four or five out of fortythree gives percentages of 9.3 or 11.6 with some form of arthritis. Whether these figures are actually representative of the Easter Island population is hard to say because of the small size of the sample and because Ahu Hekii crania were not accompanied by any postcranial remains (Table 1). The spinal osteophytosis may be due to prolapse or degeneration of the intervertebral discs, possibly associated with greater age. The etiology of rheumatoid arthritis, ankylosing spondylitis perhaps being a spinal form of rheumatoid arthritis, is unknown, although infection may play some part, according to Collins (1949). The infection might have been streptococcal or possibly tubercular (specimen 3 above). Also a hereditary predisposition is possible, particularly in a small inbred population such as existed on Easter Island.

V PATHOLOGY y

rioGERS (1954) has pointed out that dry bone material can yield only limited information about the general health of a population. This is particularly true here because of the small size of the sample and the lack of certain bones — vertebral columns, for example. But there are eight pathological specimens, probably representing eight individuals: Adult Male Cranium. Hypertrophic lipping of the left and right processus clinoideus posterior of the dorsum sellae, probably owing to age. About 2.5 cm above the left orbit on the frontal bone is a triangular depression, which is perhaps the result of a depressed fracture, or possibly due to yaws (PI. 8, middle left; see also Brothwell, 1963, PI. 10, B and C). Adult Left Humerus, Probably Male. Marked bending medially of the upper end of shaft, the result of a fracture, substantiated in an X-ray picture. The hole seen opposite the maximum bending in the illustration is not a lesion. (PI. 8, top left.) Adult Right Tibia, Male. The head of the fibula is fused to the head of the tibia. This may be a case of tuberculous arthritis. (PI. 8, top middle.) Two Thoracic Vertebrae, Adult, Sex Unknown. The articular facets are not fused and the intervertebral foramen can be clearly seen. The ligamentum longitudinale anterius has become ossified on the anterior right side of the vertebral bodies. This is a case of ankylosing spondylitis or spondylitis ossificans ligamentosa. (PI. 8, left and right bottom.) 55

Plate 8. BONE PATHOLOGIES.

Aguera (1908, p. 90) in 1770 says that "The country inland . . . appeared to us to be fertile, as we observed . . . various valleys and plains . . . quite covered with greenery as far down as the sea beach, showing the fertility of the country." Forster (1777, p. 598), who accompanied Cook, speaks of "the barren refractory soil of their island." La Perouse (1799, p. 323) wrote of his 1786 visit: "Scarcely a tenth part of the island is cultivated, and I am persuaded that three days' labour of each Indian is sufficient to procure subsistence for a year." He also says that "The ground is cultivated with great skill. The natives collect the grass and other vegetables, which they heap together and burn for the sake of the ashes, as a manure." (P. 328.) Beechey (1832, p. 41) says, "the valleys were well cultivated, and showed that the island required only a due proportion of moisture and labour to produce a luxuriant vegetation." Skottsberg (1928) has pointed out that the soil was of good quality and fertile when properly cultivated, and that in prehistoric and early historic times extensive plantations supported a population of several thousand people. Tradition attributes to the first colonists, led by Hotu-matua, the introduction of taro, sweet potatoes, yams, bananas, sugar cane, ti (cordyline fruticosa), turmeric, gourds, arrowroot, nightshade, and paper mulberry trees (Metraux, 1940). The plants were cultivated and flourished. Coconuts and seedlings of the breadfruit tree must also have been brought, but they did not survive the Easter Island climate. Bananas and other plants that could not withstand the cold blast of the sea winds were grown in sunken gardens. Metraux (1957, p. 65) says that "The future harvests were preserved from theft, and even from the impatience or greed of their owners, by a tabu pronounced by the king himself or by some priest of the royal line." Chickens, pigs, and dogs were undoubtedly brought, but only the chickens survived the journey. Black rats also were introduced and were regarded as a delicacy. Fishing was in the past important. Thomson (1889) mentions bonito, albicore, ray, dolphin, porpoise, swordfish, shark, rockfish, eels, turtles, crayfish and shellfish. Metraux (1957) speaks of tunny, and of

VI CLIMATE, WATER, SOIL, AND DIET

1 HE

climate of Easter Island is very mild and equable. Skottsberg (1928) gives a mean annual temperature of 67°F (19.7°C) for 1912-13. There are constantly blowing winds and noticeably cold nights. The annual rainfall for the years 1901-05 and 1912-13 averaged 50 inches. Some years are very wet, and some very dry; there are no prolonged droughts, and heavy downpours are by no means rare. Metraux (1957, p. 65) states that "Drinking water has always been a difficult problem for the natives. Easter Island has no river . . . the rain quickly soaks into the porous soil and forms underground water tables that flow into the sea at beach level . . . unfortunately, these rivulets emerge so close to the sea that their water is brackish." He found a few springs of low output and fresh-water lakes at the bottom of craters. The natives drank the brackish water but mainly quenched their thirst with the juice of sugar cane. The early voyagers' accounts of the soil and cultivation are of some interest. Roggeveen (1908, p. 21) wrote of his 1722 visit: "This place, as far as its rich soil and good climate are concerned, is such that it might be made into an earthly Paradise, if it were properly worked and cultivated." 57

women and girls making daily visits to the beaches to gather sea urchins, crabs, and sea slugs. He also says (p. 67) that "In ancient times fish were the object of a tabu during all the months of the southern winter." It occurs to me that this might partly explain the cannibalism that was prevalent, since Metraux (1957, p. 103) says "cannibalism was not exclusively a religious rite or the expression of an urge for revenge: it was also induced by a simple liking for human flesh that could impel a man to kill for no other reason than his desire for fresh meat." Food was cooked in a pit with a fire at the bottom, that is to say in a typical Polynesian umu or underground oven. This method of cooking results in succulent food. Metraux (1957, p. 72) points out that although it is hard to determine the proportion of each foodstuff in the daily menu, nevertheless "the diet of the ancient Easter Islanders seems to have been very well balanced and not to have been lacking in any element essential to health." The upper strata of society such as the ariki-mau or great chief, the ivi-atua or priests, the ariki-paka or nobles, and the matatoa or warriors in times past may have had more and better food than those lower in the social scale. Also the best agricultural land was doubtless concentrated along the coast (Sahlins, 1958) possibly producing dietary differences between inland and coastline. Various collections of Easter Island crania contain skulls that have engraved designs of different shapes on the frontal bone. It is believed that these are the crania possibly of warriors or perhaps more likely ariki (Brown, 1924). In the present sample there is one such skull, namely No. 1 from Ahu Vinapu (PI. 9). If one compares the measurements and indices of this skull, as shown in Tables 4A-4D, with the means of all the males, shown in Tables 7-10, one can see that all the incised skull means do not differ by more than two standard deviations from the means of the total male sample. This would favor the conclusion that skulls of the ariki did not differ significantly from the rest of the population. However, in this case only one ariki skull has been used in the comparison and thus the conclusion may or may not be true. Finally, I share with Metraux the belief that the

Plate 9. ENGRAVED SKULL.

general population of both sexes must have been quite adequately nourished. This is based on the dietary evidence noted above, the stature attained especially by the males, which has already been discussed, the fact that early voyagers described the Easter Islanders they saw as well-built, and the pathological evidence already mentioned.

THE main Easter Island samples antedating the present one that have been described are as follows (all numbers include both sexes): De Quatrefages and Hamy (1882), 54, collected by Pinart; Volz (1895), 49, collected by Geiseler; Meyer and Jablonowski (1901), 24, part of Volz's sample; Von Bonin (1931), 79, collected by Weisser, Routledge, and Lord Crawford; Petri (1936), 16, collected by Weisser; Henckel (1939), 8, collected by Wilhelm; Imbelloni 1951, Chilean sample, 61, collected by various individuals, and also his total sample. Only Henckel's sample includes some postcranial remains. Imbelloni's total sample includes his Chilean sample of Easter Island crania (which was obtained from various museums and a convent in Chile), all the above Easter Island samples, and some isolated Easter Island crania. Earlier Easter Island Male Studies All of the above samples except Henckel's are studies only of crania. Only for Henckel's sample is the exact locality known from which the crania and postcranial remains were obtained. In no case is there any certainty whatsoever regarding the dating of the skeletal material; this is not surprising in view of the relatively recent use of the C-14 dating tech-

nique. In most cases little information is given concerning morphological observations. All this means that one should be cautious in using and interpreting any of the above samples. Since the above strictures are equally true of all other Polynesian samples, one should also be cautious in the use and interpretation of such samples for comparative purposes. Even though the dating of other Easter Island samples is not known, it is of some interest to compare some of them. I have selected Imbelloni's Chilean sample of Easter Island crania and Von Benin's sample, Imbelloni's total sample, and my own. Eleven cranial indices of these samples are compared in Table 20. Also various measurements and angles obtained from the median sagittal craniogram are compared for my sample and that of Imbelloni's Chilean sample (I am much indebted to Dr. Imbelloni for supplying me with his original data). One is struck at once with the remarkable similarity of the cranial indices in the different samples, with the exception of the orbital index in the Von Bonin sample, which may be due to a difference in measuring technique. The same similarity can be seen in the median sagittal craniogram measurements and indices. Now the skeletal remains in my sample, as already stated, come from the Middle and Late periods. I have already demonstrated that Easter Island physical type did not differ in these two periods. // the other samples also come from the same periods then their similarity indicates a remarkable homogeneity for the Easter Island physical type in the Middle and Late periods. //, on the other hand, all the samples other than my own also include crania from the Early period, this would be an argument in favor of the similarity of the Easter Island physical type from the Early to Late periods. However, the latter speculation cannot be proved until actual skeletal remains are obtained from Easter Island that are known definitely to come from the Early period.

The Easter Island Male Physical Type: Middle and Late Periods, and Living In their excellent article on Polynesian craniology Marshall and Snow (1956b) have the following to say concerning the morphology of Polynesian crania. 59

The morphological study of Polynesian crania appears to be as important as many metrical and statistical analyses. Regardless of whether they be from New Zealand, Hawaii or Tahiti . . . from Tonga or Mangareva . . . Polynesian crania appear to be remarkably distinctive . . . in its morphological totality, a Polynesian cranium distinctly differs from a Melanesian or Micronesian cranium. The most striking peculiarity of Polynesian cranial samples is the characteristic "rocker jaw." (P. 414.) The "type" Polynesian male cranium has the rocker jaw, an exceptionally flat temporal area coupled with large parietal bosses [their Table 1 shows mostly small to medium parietal bosses], which leads to a "rhomboid" form, a variable degree of flattening at lambda [mostly absent to small in their Table 1], marked nuchal muscularity, relatively sloping frontal area, large mastoids, and supramastoid crests, a prominent glabella and medium to large brow ridges, concave-convex nasalia . . . (p. 414).

The Polynesian face, as reflected in those from Mokapu, Oahu, Hawaii, has a narrow forehead, but orbits, noses and faces of average proportions . . . the Polynesian malars are typically large in size with considerable anterior prominence (p. 415). Nasal fossae with interesting double rounded sills to the lower margins of the nasal apertures [fossa praenasalis], are common. Nasal spines are of a small to average size. Another common characteristic is the narrow-rooted nature of the nose bones. Both upper and lower jaws are large in size, show little anterior projection. (P. 416.) Compared with the above morphology what is the morphological configuration of this Easter Island male sample? I refer the reader to Table 13 and to the above paragraphs. First and foremost, 35.3 per cent of the Easter Island male sample has the "rocker" type mandible. Parietal bosses are mainly small to medium and the cranial form in the norma verticalis is ovoid or

pentagonid rather than rhomboid. The lambdoid flattening is mainly slight to small, nuchal muscularity is mostly medium. The frontal area is relatively sloping, although not so much as in the Mokapu Hawaiian male (Fig. 4). The frontal slope and frontal curvature angles are 17.6° and 130.3°. The mastoids are medium to large, supramastoid crests mostly medium to large, glabella is mostly medium to large, the supraorbital ridge is medium to marked in 57.9 per cent, and the nasal profile is mainly concave. In general, the Easter Island face has a narrow forehead with orbits, nose, and face of average proportions. The malars are mostly medium to large with slight to medium anterior malar projection. The lower margin of the nasal aperture shows the presence of the fossa praenasalis in 38.9 per cent of the males. Nasal spines are mainly small to medium. Nasal root width is narrow to medium in 89.5 per cent. The mandible is mostly medium to large in size. The facial profile angle is 87.3° or orthognathous. Of interest here is the presence of precondylar tubercles in 27.8 per cent of the Easter Island sample. Marshall (1955) shows, for the larger male

61

samples he lists, the following male figures: adult Maori 13.8, Chatham Islands (Moriori?) 20.0, Hawaii (Mokapu) 11.2, Tahiti 12.5, or a range of 11.2-20.0 for Polynesia; Fiji 11.1; and Guam 20.0. These figures include precondylar tubercles of the types I and II of Brown (1957). The latter's figures of types I and II for American White and Negro males are 10.1 and 7.1 per cent. Another interesting character is the persistence of the supranasal portion (N) of the medio-frental suture. Ashley Montagu (1937) examined some 2104 adult skulls (sex?) of forty different groups of mankind; 44 skulls, or 2.1 per cent, had N. Of the 44 skulls, 32 or 72.7 per cent were from Polynesian populations. The character is present in 38.9 per cent of the Easter Island males. De Young (1941) examined additional Polynesian groups for this character. His figures, which include those of Ashley Montagu, show a range of 1.6-21.2 per cent. His figure for Guam, Micronesia, is 30.0 per cent. Ashley Montagu's only figure for Melanesia (New Caledonia) is 11.1 per cent, based on a sample of 9 individuals. Thus the figure for Easter Island in this sample is the highest of the Polynesian populations. Ashley Montagu (1937) also shows a range of 0.9-1.5 per cent for metopism for different Polynesian populations (sex?). The Easter Island male figure is 11.1 per cent. Thus it can be seen that the morphology of the Easter Island male cranium of the Middle and Late periods is indubitably Polynesian. Table 21 shows a comparison of the male Easter Island crania and height with the male living Easter Islander, using the data of Shapiro (1940b). The difference in the maximum length and width measurements and the cephalic (cranial) index is what one would expect if one takes into consideration the increase in the direction of brachycephaly that has occurred in Polynesia (Marshall and Snow, 1956b), in this case a post-Late period phenomenon and a change from 70.8 to 74.6 (Shapiro, 1940a) or 76.3 (Bormida, 1951b). The differences between the crania and the living in the minimum frontal, bizygomatic, bigonial, and total face height are about what one would expect in this case if one considers tissue thickness. Also, both samples are small, which might introduce flue-

tuations having nothing to do with tissue thickness. (Shapiro, personal communication, 1960.) The similarity in stature is of considerable interest. Also morphological traits such as skin color, hair form, width of nose, and lip thickness of the living Easter Islander fall well within Polynesian limits (Shapiro, 1940b). Once again the Easter Islander of the Middle and Late Periods indicates his Polynesian affinity. Male Easter Island Crania Compared with Crania from Polynesia, Micronesia, Melanesia, and Australia Table 22 compares thirteen measurements and ten indices of the crania of Easter Island with available published Polynesian samples from the islands of New Zealand (Maori), Chatham (Moriori), Marquesas, Cook, Society, Hawaii, Tonga-Samoa; a Micronesian sample from Guam; a Melanesian sample from Santa Cruz, and an Australian sample (see Fig. 5). The mean deviation of the measurements and indices of each sample from that of Easter Island is shown. Once again one must remember that in all the

population samples used in this comparison, with the exception of the Easter Island sample, the actual site from which the crania came is in general not known: the dating of the crania is also unknown, although presumably the crania predate European contact; no morphological observations are included or postcranial remains and, finally, the numbers involved in ten of the eleven samples are small. Thus there is little point in using complex statistics. Also, to complicate matters, Snow has remarked that "our big problem throughout the Pacific and with populations of all East Asia centers about the custom of head-shaping, a cultural mark. Certainly in Hawaii this was common. I have reason to believe that most cranial series measured by most of the older authorities . . . contain deformed skulls — the result of the head-shaping practice common in all the area." (Personal communication, 1960.) Nevertheless it is interesting that the comparison reveals the following. The mean deviation from Easter Island in Polynesia ranges from 3.59 to 8.19, with the figure of 6.64 from Guam (Micronesia) falling within this range. The largest mean deviation figures are 10.95 from Santa Cruz (Melanesia), and 11.73 from Australia. These figures indicate a certain degree of homogeneity in Polynesia of the measurements and indices in question, with Easter Island deviating the least from the Society or Cook Islands, and the most from Santa Cruz (Melanesia) or Australia. This cranial comparison, then, though we must keep in mind its limitations, reaffirms from a metrical point of view Easter Island's Polynesian affinity, denies its Melanesian or Australian affinity, and suggests a Polynesian-Micronesian affinity, admittedly on the basis of only one Micronesian sample. I might add that in a D2 statistical technique study Marshall (unpublished manuscript) states: Almost as striking as the similarities of Tahitian crania to all other oceanic crania are the contrasting dissimilarities of Easter Island crania . . . Easter Island crania differ more from several other Polynesian series than do the culturally and "racially" distinct Melanesian Fijians . . . Yet, considered within the same set of data, almost as dramatic is a strange degree of similarity between Easter Island, Tahiti, and the far distant Melanesian series from Fiji. He later points out, however, that "There may

have been a continuous interchange of genes between local groups or subgroups, as in the case of Tahiti, or there may have been marked genetic isolation, as might well have been the case in Easter Island." If this is true, any Easter Island-Melanesian similarity may be quite accidental and have no genetic significance. Besides, Marshall is not using any morphological characters in his analysis, such as the important "rocker" mandible. Without knowledge of the provenience and dating of the crania, the use of such a complicated statistical technique is indeed debatable. The latter point is, in my opinion, of considerable importance and has been clearly stated by Roberts (1954), who maintains that it is risky to use D2 in the initial stages of an analysis for the following reasons.

ters; or (b) to differential direct or indirect environmental modification of the phenotypic characters during ontogeny (the groups being genotypically identical); it is probable that most morphological features are the expression of interactions between both genetic and environmental components. The second group must be considered and allowed for in discussing questions of racial affinity, which in the final analysis must rest on the first group. D2 removes some of the difficulties complicating discussion of multivariate differences, but can it be said to have touched this essential problem? The awesome computations must not be allowed to distract attention from the fact that a table of D2 values relating to samples living in different localities may only indicate that the samples do inhabit different localities! As obtained in all studies yet published, a matrix of D2 values does not necessarily indicate degrees of racial affinity.

The slight recompense for the amount of computing time involved is the first criticism. At the expense of considerable time and labour, information about the data is augmented by the sum of the differences in metrical characters after their intercorrelations have been allowed for, by the size of these differences relative to each other, and by the probability of their occurrence. But how great a gain is this? The object most frequently envisaged in the use of metrical features is the establishment of racial affinities and non-affinities. Metrical differences between groups may be due (a) to differences in genotype, arising from differential hybridization, or from drift in the case of non-adaptive "neutral" characters (if such exist), or from selection in adaptive charac-

The Validity of Comparing Male Easter Island Postcranial Remains with Those of Other Polynesians The comparative published Polynesian postcranial remains of a usable sample size are almost nonexistent. About the only published sample is of Maori remains (Scott, 1893). In this case it is not clear if the postcranial remains belonged to his Maori cranial sample, or from which island of New Zealand they were obtained; nor is the material reliably dated. Therefore, at this stage, I believe it is wisest to wait until there are better published samples for comparative purposes.

racial likeness, which employs only metrical observations and thus omits morphology, decided that the Easter Islander had no racial affinity to such fringe races as the Maori, Moriori, or Ainu. Morant, in a note to Von Benin's paper, and also using the coefficient of racial likeness, concluded that Easter Island and Loyalty Island (Melanesia) crania resembled each other. On this point Shapiro (1940a, p. 7) has the following to say: "the Loyalty group is not especially characteristic of Melanesians and their relationship with certain Polynesians may as well be explained on the basis of Polynesian admixture with the Loyalty Islanders as on the assumption of a Melanesian addition to the Polynesian groups." Wagner (1937), also using the coefficient of racial likeness, had some interesting comments to make regarding Polynesia: In several characters the Polynesian races combine into a natural craniological group which differs rather sharply from the Australian, Tasmanian, Melanesian (S.E.) and Papuan. . . . the proportions of the three parts of the sagittal are, orbital and nasal indices, profile angles and palatal index. (Pp. 143-144.) Everyone who works with Polynesian skulls will come across isolated specimens with striking Melanesian features. But it is a question . . . of prime importance whether it is justifiable to pick out particular skulls (dolicocephalic), and treat these separately as Melanesian mixture types. (P. 154.)

VIII FORMER THEORIES AND A LEGEND

JDASING their assertion on cranial, height-length, and height-width indices, De Quatrefages and Hamy (1882) saw Melanesian traits in several Easter Island crania. Volz (1895), using the above indices and mainly such a morphological observation as the size of the supraorbital ridge, concluded that the main components of the Easter Islander were Melanesian, Polynesian, and Australian. Meyer and Jablonowski (1901) did not agree with the idea of a Melanesian element in the Easter Island crania; on the contrary, they believed they were Polynesian. Dixon (1923, p. 380) on the basis of the cranial, lengthheight and nasal indices, concluded that the Easter Island population was composed of "Proto-Negroids" mainly, "the minority being made up of the Caspian, Proto-Anstraloid and Palae-Alpine in nearly equal proportions" — a veritable witches' brew! These scientists' methods of analysis, which use cranial types based on a few indices to represent the racial components of a population, omit morphology and are outmoded. As Shapiro (1940a, p. 12) has stated, "Such statistical figments are moved about in an arbitrary manner to account for variations and to establish relationships with equivalent figments similarly arrived at in other areas." Von Bonin (1931), using Pearson's coefficient of

The Easter Island cranium in particular, he pointed out, is long, narrow, and high, and the three main indices are similar to the Loyalty Islands and New Caledonia (Melanesia). However, the mean values for the three components of the sagittal arc and the corresponding indices fall within the Polynesian limits. And the same is true of the various measurements and indices of the facial part of the skull. . . . The nasal index . . . the mean values of 51.0 for males and 52.5 for females are indeed the highest among the Polynesian figures, but they are clearly less than those for certain Melanesian groups. . . . More surprising is the profile angle. The Easter Islanders are more orthognathous than the Maori, Moriori, Marquesans and Sandwich Islanders. (Pp. 160-161.) I would also point out that the Easter Island external palatal (maxillo-alveolar) index falls into the Polynesian range. 66


Finally, Wagner (p. 162) stated that "One cannot avoid the conclusion that the Polynesian races have branched out and given rise to characteristic skull types. I believe it probable that this process has had more influence than mixture with a foreign Melanesian element." Henckel (1939), on the basis of only eight crania, believed that the Easter Islanders were mainly Melanesian. Imbelloni (1951) favored the idea of an earlier Negroid and later Polynesian migration to Easter Island. Most of these authors believe in a Melanesian element as well as a Polynesian one in the Easter Islander. On the basis of metrical observations only, Wagner points out clearly the Polynesian affinity of Easter Island crania. I agree with him and would add that the morphological observations which I have described in some detail confirm this conclusion. I repeat, however, that my sample from Easter Island has crania only from the Middle and Late periods. Finally, if there was a definite Melanesian element in the Easter Island population, why is there so little trace of characteristic Melanesian morphological traits in the living Easter Islander (Shapiro, 1940a)? The legend of the war between the Long-ears (Hanau-eepe) and the Short-ears (Hanau-momoko) is well-known to anyone familiar with Easter Island ethnology. Briefly, for reasons not exactly clear, the Long-ears took refuge in the Eastern headland or Poike. They dug a ditch across the headland and filled it with brushwood for a fire. A Long-ear told his Short-ear wife that the ditch was to become an oven for the Short-ears. The wife told the Short-ears of the Long-ears' plan, and betrayed her husband by helping the Short-ears to reach a position behind the Long-ears. The Short-ears then chased the Long-ears — men, women, and children — into the burning ditch and all were killed except two men who escaped to a cave. The Short-ears followed, killing one of the survivors and leaving only one Long-ear alive. There has been some doubt about whether a battle actually ever occurred, but apparently it did, according to one of the carbon-14 dates obtained. Smith (1961, p. 212) says that "The legendary war between the Hanau-momoku and the Hanau-eepe is

67

dated at A.D. 1676 ± 100 years on the basis of sample K-501 which was taken from the burned layer in the fill of the Poike Ditch . . . where the decisive battle took place." Metraux's (1940) informant said the Long-ears and Short-ears were part of Hotu-matua's crew. Since Hotu-matua was the leader of the Polynesian immigrants, the Long-ears and Short-ears must both, in this version, have been Polynesian. Routledge (1919) was impressed with the Negroid (Melanesian) element in Easter Island crania, and although she did not actually say that the Long-ears were Negroid and antedated a later Polynesian wave, one gets the impression she may have thought so. Wilhelm and Sandoval (1956) maintained that the Hanau-eepe were corpulent and long-eared (?) and arrived after the Hanau-momoko who were slender and came with Hotu-Matua. Later the Hanaumomoko also lengthened their ears. Even today, they go on, the descendants of the Hanau-momoko are tranquil, whereas the descendants of the Hanaueepe are dynamic and restless. The remainder of the report is even more confusing. I gather from their genealogical research that the descendants of the Hanau-eepe are only of blood type O, and the descendants of the tribes Mini, Tupahotu, and Marama Raa (Hanau-momoko?) are of both blood types, O and A. What all this is supposed to prove escapes me. (See my discussion of blood types on pp. 77-79 and Tables 23-25 below.) Heyerdahl (1960, p. 345) identifies the Long-ears as Peruvians (white men with red hair?) antedating the Short-ears who were Polynesians (Indians of the northwest coast of America?). The latter arrived at Easter Island only during the last century before the coming of the Europeans. Elsewhere Heyerdahl (1961, p. 37) mentions Knoche's statement that the Short-ears arrived at Easter Island in the middle of the thirteenth or fourteenth century. The above will suffice to show the general confusion that exists regarding the legend. I have already had occasion to point out that the physical type on Easter Island from the Middle and Late periods (after about A.D. 1100) was Polynesian. It is extremely unlikely that the Early-period population was Negroid. It appears that in A.D. 1676± 100 there was a

68


battle at the Poike ditch, between, it is said, Longears and Short-ears, with, mark you, one Long-ear survivor. And yet when Captain Cook visited Easter Island on his second voyage to the South Seas (177275) he saw numerous individuals with distended earlobes. Either there was more than one Long-ear survivor of the battle, or the Short-ears took over

this custom, or the battle took place after Cook's visit (Suggs, 1960b). If the legend is basically accurate, as well as the C-14 date for it, and although the problem is unsolved, it is my opinion that the Long-ears and the Short-ears were both Polynesians and that more than one Long-ear survived.

IX THE VALIDITY OF HEYERDAHL'S THEORY OF THE POPULATING OF POLYNESIA

I G A T H E R that Heyerdahl (1952) believes that there were two separate migrations from the American mainland into Polynesia. The first consisted of people from a pre-Inca civilization centered near Lake Titicaca and the Peruvian coast below; these people were apparently Caucasoids, whose original home was possibly northwestern Africa or the Canary Islands! The second consisted of people who left the northwest coast of North America, specifically the Kwakiutl or Nootka area, voyaged to Hawaii, and from there populated the rest of Polynesia. The migration to Hawaii occurred about A.D. 1000. Presumably, then, this second migratory wave of people mixed with and engulfed genetically the people of the first migration. I am concerned here mainly with the evidence from physical anthropology for Heyerdahl's theory. Almost the only skeletal evidence he gives for his second migration is to compare the cranial index of eleven males and sixteen females from different areas of the Northwest Coast Indians as given by Hrdlicka (1944) with the cephalic index of six Polynesian groups as given by Shapiro (1940b). The male aver73

age Northwest Coast Indian cranial index was 81.1 and the average cephalic index for the male Polynesian groups 81.2. Obviously, apart from comparing the dead with the living in this case, to use only the cranial index of the dead Northwest Coast Indians is simply insufficient. Heyerdahl's main evidence for the first migration seems to be the Paracas Necropolis Indian mummies from Peru: "it can safely be said that nothing discovered in the Paracas caves argues against the hypothesis that a foreign Caucasian-like race entered into the culture complex of pre-Inca Peru" (1952, p. 324). Heyerdahl used the studies of Paracas Indian skeletons by Stewart (1943) and of Paracas Indian mummy hair by Trotter (1943). Apparently he was much impressed by the fact that the ten male Paracas skeletons had longer femora (maximum length L 431 mm, R 429 mm) than femora from five hundred skeletons from Pachacamac on the Central Coast (L 414 mm, R 410 mm), femora from two hundred skeletons from Chicama on the North Coast (L 418 mm, R 413 mm), or femora from fifty-two skeletons from Pancarcancha in the Southern highlands (L 401 mm, R 395 mm). Also, the crania from Paracas had narrow facial features. Heyerdahl was equally impressed with the fact that the Paracas mummies, eight males and two females, had "hair in varying shades of brown, fine in texture, and occasionally wavy" (1952, p. 325). He says a page earlier, "neither stature, cranial [the Paracas crania were artificially deformed!] and facial indices, nor hair, have been found to concur with the familiar norm of local Indians" (1952, p. 324). The above constitutes his evidence that the migrants were Caucasoid. Actually Trotter said that the hair in general was rusty brown. However, though two samples had a wavy hair form, the mean hair form index (smallest diameter X 100/greatest diameter) of 81.81 was midway between the 79.77 of Mesa Verde Indians and the 82.81 of Basket Maker Indians. Moreover, 81.81 is within the range of indices for Zuni, Navajo, Hopi, and Maya Indians: 80.4685.04. In cross-sectional area the Paracas hair was small when compared with other Indians', but larger than Dutch hair. I have considered it worthwhile to assess the

74


validity of Heyerdahl's theory from a skeletal point of view. Table 26 shows the means of male cranial and postcranial measurements, indices, and angles of Hawaiians, Nootka, Kwakiutl, Society Islanders, Easter Islanders, and Paracas mummies. Once again there are certain limitations. The Hawaiian material is prehistoric (A.D. 1150-1750; Snow, personal communication). The Easter Island material falls into the ca. 1100-1868 A.D. date range, and the Paracas material is said to be 306 B.C. ± 200 (Arnold and Libby, 1951) or A.D. 206 ±90 by the carbon dioxide method (Broecker et al, 1956). The Nootka, Kwakiutl, and Society Island materials, to the best of my knowledge, have not been dated; possibly they are prehistoric. Morphological observations are lacking for the Society Island and Paracas crania. Oetteking (1930) gives average morphological observations for the crania showing the "koskimo" type of artificial deformation; his group includes other tribes besides the Kwakiutl and Nootka, such as the Nimkish, Koskimo, and Clayoquot. Postcranial measurements and indices are lacking for the Nootka, Kwakiutl, and Society Islanders. Cranial measurements and indices are limited because the Paracas, Nootka, and Kwakiutl crania were artificially deformed. Nevertheless, the comparison in Table 26 is interesting. Since Heyerdahl maintains that his second migratory wave populated Polynesia from Hawaii, I have calculated the mean cranial and total mean deviation of the various populations from the Hawaiian figures. It can be seen immediately, despite the fewer Society Island measurements, that the Hawaiians are closer to the Society Islanders than to the Nootka or the Kwakiutl. True, the Easter Island figure falls into the range of the Nootka and Kwakiutl figures, but the Nootka-Kwakiutl ("Koskimo") and Hawaiian morphological observations have not yet been mentioned. The Paracas mean cranial and total mean deviations are by far the largest figures, indicating little if any similarity between Paracas and Society or Easter Islanders. Table 27 shows the morphological observations of the Nootka-Kwakiutl ("Koskimo"), Hawaiians, and Easter Islanders. Of those features which can be compared in the three groups, seven out of twelve, or

58.3 per cent, are most common in the Hawaiians and Easter Islanders. In the remaining HawaiianEaster Islander comparisons, twenty out of twentythree or 86.9 per cent are similar. Thus on the basis of morphological observations there can be no question of the Hawaiian-Easter Islander affinity; both are obviously Polynesian. Table 26 shows that the maximum length of the Paracas femur (L 431.0 mm, R 429.0 mm) is considerably less than that of the Easter Islanders (L 452.1 mm, R 446.2 mm): the Paracas people were not so tall as Easter Islanders. Also, as mentioned above, Heyerdahl did not believe that the Paracas people were similar to local Indians. Table 28 compares the measurements and indices of Paracas mummies given by Stewart (1943) with Peruvian Central Coast Incised (850-500 B.C.; Mason, 1957) and Late Chancay (A.D. 1300-1500; Bennett, 1946) skeletal material (Newman, 1947), and Easter Island. The mean cranial deviations from the Paracas mummies of both the Incised and Late Chancay are very similar, and much less than that for Easter Islanders. Furthermore, the Incised and Late Chancay similarity — mean cranial deviation 0.78 —suggests, according to Newman, "the virtual absence of statistically significant differences between the Incised and Late Chancay male series" (1947, p. 22). From a skeletal point of view, therefore, not only are the Paracas mummies similar to the early Peruvian Central Coast Indians but the latter remained relatively unchanging over a fairly long period. I cannot, for this reason, conclude that the Paracas mummies were Caucasoids; on the contrary, they were similar to other Peruvian Indians. Heyerdahl (1952) maintains that since there is ample evidence to support the Aztec and Inca tradition that European-like peoples lived in parts of America before the Spaniards, the burden of proof and explanation rests with those who believe that prehistoric America was strictly the home of Mongol types. I would say that the burden of proof, from the point of view of physical anthropology, still rests with Heyerdahl to conclusively show particularly that his first migratory wave of people into Polynesia was from the American mainland and was composed of Caucasoids.

Hekii, 26-33. These samples I gave to Professor Charles A. Leone of the Department of Zoology, University of Kansas, who had kindly consented to do the necessary laboratory work. I am concerned here only with the results shown in Table 23. Unfortunately there is some doubt about the actual blood group of some of the samples, as their presumptive blood types indicate; this means that more than one possibility exists concerning the results. Three gene frequency results were therefore calculated, as shown in Table 23. Result number one omits the presumptive blood types A(?), or O and B(?), or O. Result number two accepts A(?) as A and B(?) as B. Result number three accepts A(?) and B(?) as O. I gather that Leone and his assistant Caskey would probably favor the last possibility. This attempt to discover the blood groups is a good object lesson. Quite apart from the possible errors mentioned by Thieme and Otten above, and the small size of the Easter Island sample, one is faced here with at least three possibilities in interpreting the results, which raises the question whether one can use these results at all. This point, as well as the interpretation of these results, will be discussed below. I should state at the outset that I believe it a grave mistake in physical anthropology, when trying to trace the migrations of various races or attempting to determine the racial affiliation of a particular population, to rely only on blood group gene frequencies. One should not omit the product of the genotype and various environments, the phenotype — in other words, the morphological and metrical observations. Furthermore one should not rely only on physical anthropology but should also pay attention to evidence from the other divisions of anthropology, linguistics, ethnology, and archaeology; the latter are almost if not entirely absent from the earlier Easter Island craniological studies. There are numerous pitfalls in the use of blood group gene frequencies. Suggs (1960b) makes a startling revelation about the collecting of blood samples on the island of Nuku Hiva, Marquesas, during Heyerdahl's 1956 expedition to Polynesia. Suggs, who was on the island at the time of the collection, maintains that of the twenty-four Marquesan

X ABO BLOOD GROUP GENE FREQUENCIES

ALTHOUGH Smith (1960) is rather optimistic about using paleoserology as a tool for the anthropological study of gene flow in the past, others, such as Thieme and Otten (1957), are somewhat less enthusiastic. In fact the latter have said: The accuracy of bone typing is seen to rest upon the amount and chemical integrity of antigenic remains in bone, undestroyed and untransformed by bacterial enzymes, and upon the reliability and specificity of indicator tests. The inhibition test has been seen to offer numerous potentialities for error in unequal or total destruction of test antisera by contaminants present, in unequal non-specific absorption leading to false interpretations, the presence of adventitious antigenic elements which cannot be distinguished from blood group substances, and the possibility of the influence of bacterial enzymes upon the test-cells themselves. (P. 395.) Another point to keep in mind is one made by Laughlin (1951); namely, that gene frequencies from large populations are more reliable than those from small populations, because small populations are more subject to genetic drift or accidental loss of genes. In spite of these reservations I thought it would be worthwhile to try to discover the ABO blood group gene frequencies of the total Easter Island sample. I obtained bone samples from either long bones or skull fragments representing separate individuals and numbered as follows: Ahu Tepeu Grave 1, 1-2; Grave 2, 3-12; Ahu Vinapu, 13-25; Ahu 77

blood donors only two were of pure Polynesian ancestry. I cannot resist repeating his description of one of the donors, Tahia by name. Dear Tahia went along for the ride, so to speak, and gave a cc. or two of vital fluid to science. It would be difficult to describe her actual ancestry in a brief fashion. She is the granddaughter of a Castilian Spaniard, Alvarado by name, who jumped ship in the Marquesas to live out his life there, and left behind a sizable number of progeny and a wicked reputation. Her father, half Marquesan, married a woman who was also a half-breed herself, with the result that Tahia and her sisters were endowed with a light skin and completely European features. If her blood type resembles that of any pure Polynesian, it does so by sheer chance, because she is genetically and physically half European. (P. 215.) This account may or may not be true. But I am sure that such individuals as Tahia have been included elsewhere in the world, probably unintentionally, in supposedly pure native samples. Simmons, Graydon, and Semple (1953) in a blood group genetical survey in Micronesia of Palauans, Trukese, and Kapingas said nothing about the ancestry of the Palauans. The forty-six Kapingamarangians were not from Kapingamarangi, but were living on Ponape, where I did some research in 1947. The authors remark of the Kapingamarangians that "there were five brother-sister combinations and several half-brothers and sisters in the group" (1953, p. 4). Simmons, Graydon, Semple, and Fry (1955), in a blood group genetical survey of Cook Islanders say that "the first lot of blood samples was collected without critical anthropological selection on Rarotonga . . . The second lot in which some attempt at selection was made consisted of samples collected on Rarotonga . . . and samples collected on Aitutaki . . . The samples were all taken from adult individuals who, on preliminary questioning, were thought[!] to be unmixed Cook Islanders." (P. 66, 8.) The same paper points out that probably only 41 per cent of the Cook Islanders are of unmixed origin. Salzano (1957), in a paper on South American Indian blood groups, pointed out that "the model utilized for the calculation of the gene frequencies assumes random mating, absence of selection, genetic equilibrium, and an infinitely large population. It is evident that in almost the totality of the cases studied

one or more of these requirements was not fulfilled." He goes on to say that one should also beware of "inadequate sampling, with the inclusion of a considerable number of genetically related individuals." (P. 574.) The above examples are sufficient to suggest not that one should throw out the blood group evidence as a nightmare of uncontrollable variables, but that if one is going to use such evidence he should do so with some caution. I have already described how the blood groups were secured from the present Easter Island sample. The three possible gene frequency results are shown in Table 23. It must be emphasized that I am dealing here only with the ABO blood group system because as yet it is not possible to get results for the MN and Rh blood group systems from ancient skeletal remains. Thus one obviously faces an initial handicap, not to mention the pitfalls described above. Be that as it may, I have tabulated in Table 24 the ABO blood group gene frequencies for various recent tribes or island populations from East Asia, Indonesia, Micronesia, Melanesia, Australia, Polynesia, North and South America; also the ranges of each gene frequency are shown and the three possible Easter Island results which are from the approximate time period of ca. A.D. 1100-1868. If we take Easter Island result number two, it is rather close to the Siamese figures. Result number one is closest to, roughly in this order, Melanesia, Micronesia, Indonesia, and Polynesia. Result number three is closest to Polynesia, Melanesia, and Micronesia. None of the results is particularly close to the Americas, especially South America. Of greater interest is that as one moves from East Asia to Polynesia there is a rough decrease of the average B gene frequency: Siam .257, Indonesia .164, Micronesia .178, Melanesia .128, Western Polynesia .100-. 118, and Eastern Polynesia O. The B gene frequencies for Australia and North and South America are almost O; the A gene frequencies roughly increase. Because there is now considerable evidence that the original home of the Polynesians was in Southeast Asia (Suggs, 1960b), one could assume that when the early Polynesians migrated east to Oceania they possessed group B, contrary to the opinion of


Simmons et al. (1955) who believe they lacked it "because of its absence in widely scattered groups of people in the area" (p. 671). They also believe that where group B is present in Polynesia, it came mainly from Micronesia and/or Melanesia. Now Polynesia is an area par excellence favoring microevolution. Through the mechanisms of isolation on islands; random genetic drift; the decimation of atoll populations because of tidal waves, hurricanes, drought, or canoes being lost at sea during offshore voyages (Vayda, 1959); varied ecological conditions; and class-structured societies that inhibited random mating, the B gene could have disappeared after a time from some Polynesian island populations, accounting for the lack of this gene today, particularly in Eastern Polynesia. The Easter Island blood group gene frequency results of this study, if they have any real validity, show the presence of group B in the period ca. A.D. 1100-1868. If Easter Islanders originally came from the Cook, Society, or Marquesan Islands, then the populations of these islands must also have formerly possessed group B; the Cook and Tahiti Islands, in fact, still show some signs of it. However, after A.D. 1868 the Easter Islanders show no group B (Shapiro, 1940), but his small sample represented the Easter Island "pure" Polynesian survivors who could easily not have possessed the group B; indeed one sample from Easter Island did possess some group B (Rahm, 1931-32). It is thus debatable whether one should agree with Graydon (1951) that the Polynesian is clearly closer to the American Indian than to either the Melanesian or Micronesian in respect to A, B, and O groups. What is needed to prove or disprove these speculations are ABO blood group gene frequencies from datable skeletal remains from other parts of Polynesia, Micronesia, Indonesia, and Southeast Asia. It is also worth pointing out that blood group polymorphism may be due largely to natural selection; similarity in gene frequencies may show convergence owing to similar environments (Mourant, 1954). There is, in fact, evidence for the ABO genes being selected by the environment. The method by which selection operates in this case is perhaps not so much malignant or degenerative diseases as various infectious diseases, "particularly since those act

79

in the early years of life and thus have a greater selective effect" (Livingstone, 1960, p. 24). Table 25 shows the MN and Rh blood group gene frequencies for various recent tribes or island populations from East Asia, Indonesia, Micronesia, Melanesia, Australia, Polynesia, and North and South America; the ranges of each gene frequency are also shown. The ranges of the M and N gene frequencies of Polynesia are closest to those of Indonesia, and the figures for the South Chinese and Siamese fall into the Polynesian ranges, though the last are not close to either North or South Americans. The ranges of the Rh gene frequencies of Polynesia are closest to North America and South America, and the Japanese frequencies fall into the Polynesian ranges. However, the Australian frequencies are close to South America. Incidentally, the South American Rh gene frequency figures to date do not agree with the statement of Simmons et al. (1955) that "the broad picture which emerges from an examination of the Rh frequencies . . . for most American Indian populations is generally the higher frequency of R2 (cDE) as compared with R1 (CDe)" (p. 685). There is really not enough comparative material yet on the blood groups P, Lea, Fya, and K. The figures we have for Lea show what may be significant differences between Polynesians and American Indians. The Diego blood group has been found in 2 to over 50 per cent of South American Indian groups, North American Indians, Chinese, Japanese, and Koreans. Polynesians, Australian aborigines, Papuans, New Britain natives, Eskimos from the eastern Canadian Arctic, and Caucasians do not have it, (Won et al., 1960), nor do various west African tribes from the Ivory Coast and Liberia or Asiatic Indians (Gershowitz, 1959). In my opinion the North and South American and Australian Rh gene frequency similarities to Polynesia are the result of microevolution, particularly isolation, random genetic drift, and varied ecological conditions. In other words, I believe on the above evidence of the ABO, MN, Rh, and Diego blood group systems that the Polynesians and American Indians came from the same gene pool and that the pool was, in all probability, in East Asia.

the original homeland for the combined eastern and western groups of Polynesian languages in the west, and language evidence suggests Tonga as being that home. [See also Elbert, 1953, p. 169.] . . . In comparing 202 basic words, it was found that Hawaii shared 76% of them in common with Tahiti, 71% with New Zealand, 70% with the Marquesas Islands, and 64% with Easter Island. With the more distantly related languages of western Polynesia, that is, of Samoa and Tonga, the Hawaiian language shared 59% with Samoa and 49% with Tonga. [See Elbert, 1953, p. 159.] We now see that Hawaii and Tahiti still shared 76% (a loss of 24%), of vocabulary in common after a separation of at least 1,000 years, i.e., A.D. 950, from carbon dating in Hawaii, to A.D. 1950. When comparing the Tahitian vocabulary with its Samoan equivalent, Elbert found 60% of the vocabulary still shared in common. Assuming that the loss in the Tahitian vocabulary of 24% in 1,000 years was at a constant rate, a 40% loss on the part of the Tahitian language would mean a separation of 1,800 years. This would place the separation of the Tahitian language from Samoa at A.D. 150. [Actually the earliest radiocarbon date (Suggs, 1960a) so far for Hawaii is A.D. 128 ± 200.] . . . To estimate how long the Tahitian language has been separated from Tonga, the possible home of the proto-Polynesian language, we note the difference between the Tahitian and Tonga languages as being a 48% loss of shared vocabulary. Again, assuming the same rate of loss for the Tahitian vocabulary, or 24% in 1,000 years, this would indicate a separation from the Tongan language of 2,500 years, or back to B.C. 550. It follows that if the above approximates what happened, we should allow at the very least another thousand years for the formation of the proto-Polynesian language, i.e., the language which gave rise to the Polynesian family of languages and set them apart from the other branches of the far-flung MalayoPolynesian family of languages. So, we should be prepared to think of Polynesia as already occupied at its western border by the people who were to shape the proto-Polynesian language, by B.C. 1,500, or earlier. [See Suggs, 1960b.] While this is just a hypothesis, remaining to be proved, disproved, or modified, the historical perspective introduced by considering the amount of language change, time involved in the change, and direction of spread, calls for a revision of thinking concerning the entry into Polynesia of the ancestors of the Polynesians. Were the Polynesian speaking people of migrant groups directly from Indonesia, we should find a stronger relationship between Polyne-

XI POLYNESIAN MIGRATIONSss WITH SPECIAL REFERENCE TO EASTER ISLAND sss

I DO not intend to cover exhaustively the evidence from the fields of linguistics, ethnology, and archaeology for Polynesian migrations, but only to point out some important conclusions that have been reached in these fields. The Linguistic Evidence Emory (1959b) has the following to say: The Hawaiian language is not only extremely close to the Tahitian, but to all the languages spoken by the native inhabitants of the islands of eastern Polynesia, and only a little less closely related to a western Polynesian group of languages, i.e, those of Samoa, Tonga, and their nearby islands. Possession of characteristics which these related languages of eastern Polynesia share uniquely would indicate a common home within eastern Polynesia. Both eastern and western groups of languages together for the same reason must also have had a common home, most probably within Polynesia. Evidence points strongly to Tahiti, the geographical center of eastern Polynesia, as being that home within eastern Polynesia for the eastern group of languages. It can be demonstrated that basic words were carried from west to east in Polynesia and then southward to New Zealand and northward to Hawaii. This fact places 80

CRANIAL AND POSTCRANIAL SKELETAL REMAINS FROM EASTER ISLAND sian and some languages in Indonesia than we find between Polynesian and languages on islands which lie between Polynesia and Indonesia. The strongest relationships, however, are with the islands in between (Grace, 1955, pp. 338-339). Evidence indicates a gradual movement of language from Indonesia to Polynesia over a long period of time. Therefore, it seems reasonable to view the arrival of man in Polynesia as having taken place through the migrations of a few small groups of canoe-borne people from islands not far to the west of Polynesia. These several groups formed the nucleus of the population which was to arise out of their descendants, and these original groups need not have come from one single island or an identical ethnic group of people. Physically the original groups need not have been entirely typical of the larger community from which they stemmed. In fact, happenstances might have resulted in those who came being on the whole, for example, considerably taller, or of lighter skin. [Italics mine; this would explain the "fair" Polynesians that both early European travelers in Oceania and Heyerdahl have described as similar to Caucasoids.] In any event, a hybrid people were formed and moved out through Polynesia, establishing on all the islands of Polynesia populations so much alike that we are not surprised at Dr. Harry Shapiro's summary of data assembled up to 1943, that the Polynesian population possesses a fundamental unity in physical appearance which necessarily implies derivation from a basic physical community. [See Shapiro, 1943.] . . . What now appears most likely is that people of somewhat diverse origins came together in a western archipelago in the Polynesian area about B.C. 1,500, and, in comparative isolation, their descendants, their language, and their culture took on the features which the Polynesians now share in common and which give them their distinctive characteristics. These early Polynesians then moved eastward to the Tahitian archipelago where again, in isolation except for an occasional stray seagoing canoe from the west or a drifting raft from Peru, language and culture took on shapes which were later dispersed by migrant groups eastward as far as Easter Island, southward to New Zealand, and northward to Hawaii, arriving at these terminal points after the beginning of the Christian year. In 1963 Emory, in a paper on settlement pattern and time involved as indicated by vocabulary agreements, says: "We have seen that Easter Island has a vocabulary, which in all probability came from the Marquesas [italics mine], and which, through the amount of its divergence and its retention of a proto-

81

Polynesian glottal, appears to have broken away from East Polynesia before the Hawaiian or the Maori. This indicates the Marquesas as a very early dispersal area." (P. 97.) Of interest here also are the recent publications of Barthel (1958a,b), who unraveled the Easter Island rongorongo script — apparently not just an assemblage of signs but a structure for which Barthel has worked out grammatical rules. He believes the Easter Island script is not unique —that it was formerly more widespread in Polynesia (see also Heyerdahl et al, 1965). As Suggs (1960b) says . . . There are scattered cryptic references to such a script's existing in the Marquesas and also in Tahiti, and the late J. Frank Stimson, a student of Polynesian philology for over fifty years, claimed to have obtained evidence of such a script in the Austral Islands (Raivavae, Tubuai, Rapa Iti). This indicates that writing was probably once part of the Polynesian cultural heritage everywhere, although its use was restricted, of course, to the priestly and upper classes for ceremonial purposes only . . . As a closely guarded secret of the powerful priests, the script may have escaped notice until its custodians took its secret to their graves. Although produced in wood on Easter Island, it was evidently written on highly perishable bark cloth in Tahiti, and on leaves in the Australs." (P. 45.) The Ethnological and Archaeological Evidence Metraux's (1940, 1957) analysis of Easter Island culture has shown conclusively that it is Polynesian. This being the case, what part of Polynesia did the Easter Islanders come from? Metraux (1957) favors the Marquesas on the basis of such Marquesas-Easter Island similarities as temple structures, whole-body tattooing, the motif in art of the tiki or human figure with large eyes, and the use by chanters as mnemonic aids of the objects symbolized in the chants. As the result of the recent stratigraphic archaeology carried out by Suggs (1960b) in the Marquesas, Easter Island-Marquesas similarities in artifact types are now apparent in the following examples: the oval or circular cross-section adzes and quadrangular section untanged adzes; rotating and incurved point fishhooks; stone squid-lure weights and large, knobbed net weights; oval houses and temples: "the early temple structure on the Ha'atuatua site could

82


represent the basic temple type from which the later Easter Island sanctuaries developed" (Suggs, 1960b, p. 175). The radiocarbon date for the Ha'atuatua Site is 120 B.C. ± 120 (Suggs, 1960b, p. 112). Also concerning Easter Island, Smith (1961) says that "the discovery of the enclosed court at Vinapu and its identification with the Early period reveals, then, a hitherto unrecognized relationship between Easter Island and cultural centers farther to the west" (p. 218; italics mine). Suggs discovered human skeletons he definitely calls Polynesian at the Ha'atuatua Site. I therefore look forward to the publication of the description of these datable remains, since it is possible, as the above evidence indicates, that Easter Islanders may have come from the Marquesas. From his own work in the Marquesas, Suggs (1960b) concludes that the settlers of the Marquesas probably arrived in the second century B.C. As he says: On the basis of the artifact types characterizing their cultural assemblage they originated in an island of Western Polynesia. This island was either in close contact with Melanesians or the culture of Western Polynesia had not been differentiated sufficiently from the Melanesian culture, for pottery, adzes, rind peelers, and ornaments are of the Melanesian type . . . the voyage of discovery was well equipped, carrying domestic plants and animals. (P. 116.) From archaeological work done on Fiji by Gifford (1951), and on New Caledonia by Gifford and Shutler (1956), Suggs (1960b) states that "the evidence at hand indicates that by approximately 1000 B.C., at least, the fringe areas of Polynesia (i.e., Melanesia) were already occupied by Malayo-Polynesian speakers bearing the antecedents of Polynesian culture" (p. 72). He also believes that the Polynesians originated on the coast of Asia. My own feeling is, however, that he has given little or no attention to Micronesia as a possible gateway to Polynesia, possibly owing to the lack of datable skeletal material and the paucity of stratigraphical archaeology in Micronesia. Finally, Duff (1959, p. 122) in a recent study of adze types, says that "nothing equivalent to the Polynesian-Indonesian-South Chinese tanged adze has been recorded from the American continent . . .

Plotted on a map, the American records are seen to be a continuous extension of the North Asiatic grooved adze, following the North Pacific littoral, while the Polynesian forms clearly suggest a transPacific extension of the South Chinese-Indonesian stepped adze." Duff does not agree with Sharp's (1957) theory of accidental voyages within Polynesia, with its implication of a chaotic pattern of culture traits, because of the clear-cut distinction between western and eastern Polynesian adze types. Duff believes radial diffusion occurred in eastern Polynesia; he thus lends support to traditional theories of the existence of such cultural centers as the Society Islands. It is worth noting that Ferdon (1961) is impressed with the following trait or complex parallels between Easter Island and particularly South America: the prepared plaza with ceremonial structures on two or more sides, the technique of fitting masonry blocks, stone houses, prepared solar observation devices, bird man cult, rongorongo mnemonic script, cremation, paintings and petroglyphs of reed rafts with masts and sails, and the weeping eye motif. Actually only the stone houses, a bird man cult, and the weeping eye motif are absent elsewhere in Polynesia. There are Polynesian parallels for the rest even though they are not in exactly the same form. Furthermore, all this merely proves what Kroeber (1948) once said: "isolated items like these cannot establish the flow or origin of whole cultures" (p. 785). I would add that I certainly do not deny sporadic contacts with South America, but the migration of peoples to occupy an area and later establish a cultural configuration is another matter. Obviously, the above parallels are drawn from archaeology and ethnology, ignoring both linguistics and physical anthropology. Finally, in a rather lengthy addendum to the shorter version of this study Heyerdahl (Vol. 2, Miscellaneous Papers, 1965) criticizes the latter in regard to the following points. The evidence for the skeletal remains from the Middle period comes from Ahu Tepeu, grave 2, and consists of "nine extended burials" (p. 327). The C-14 date for the grave 2 remains is A.D. 1629 ± 150 years. Heyerdahl states that "When Murrill in his tables (Tables 1 and 2) and text gives some of our


skeletal material a time span of ca. A. D. 1100-1680, covering the entire Middle Period, his time brackets add more than half a millenium [sic] for which he lacks any foundation in facts, and he thus suggests an important antiquity for which there is no reasonable support in available data" (p. 327). In other words, the nine extended burials (actually eleven individuals) do not constitute a representative sample of the population, and the dating puts the sample at the end of the Middle period, perhaps even into the Late period. All this is quite true, but it is equally true that the total skeletal sample constituted only thirty-three individuals, and if only "nine" datable extended burials are available so far for the Middle period, then one can only assume that they are representative, until further finds, analysis, and dating possibly prove that one is wrong. Furthermore, the dating could be A.D. 1629-150 or A.r>. 1479, which is fairly close to the middle of the Middle period. Heyerdahl also states that "cremation burials [are] . . . a markedly non-Polynesian practice" (p. 326). Concerning this point Bowen (1961) maintains that there is historical evidence for cremation on the Hawaiian island of Oahu in the early nineteenth century, for example: Both sexes were possibly cremated, as both females and males attended the king and, since not only the attendant but his or her entire family [italics mine] could be punished, all ages were possibly subject. Cremation is associated with the kanaka class. It may also have been used for members of other classes who broke kapu, but seems particularly associated with the attendants of ali'i. (P. 78.) Also, in a recent personal communication, Bowen (1965) wrote me that: Some new evidence has turned up ... namely the remains of a cremation on the windward side of Oahu, at a coastal site now located on Bellows Air Force Base property. As yet, I have not found the time to investigate these charred bone fragments carefully except to say that there seems to be only one individual involved. It was located in a shallow pit in beach sand and seems to have been subjected to considerable heat, as there is extensive checking, cracking, and discoloration — although there is little distortion. The cremation may be prehistoric or it may represent a historic carry-over of the same Hawaiian philosophy regarding this form of disposal.

83

However, no artifacts or other associated materials were present to give any clues to its age. Nor do I know whether an entire body was burned or simply an entire skeleton. I tend to favor the former idea, since bones of the hands and feet are present and these are usually neglected in secondary manipulation of human remains. Bowen says further that: As for Heyerdahl's comment that cremation is a non Polynesian practice, the Hawaiian evidence refutes this. Until my work on Hawaiian disposal of the dead, however, with its many very complex aspects, this was not recognized by people interested in Hawaiiana. This was simply because no one had combed the literature attempting to ascertain what all the types of disposal were. The evidence is clearly there, once someone begins looking for it. And now, we also have archaeological evidence — and more will probably be forthcoming. Heyerdahl rightly points out that burial customs on Easter Island were extremely heterogeneous, ahu entombment being only one of many local burial practices. Some lineages, or population groups, practiced cremation burials . . . some practiced secondary burial in thick-walled, narrowchambered and boat-shaped tombs misnamed in modern times hare moa . . . some placed [sic] extended burial in a roomy type of corbeled stone house . . . while still others simply deposited their dead in fissures and caves. However, he also states that "It is thus fully possible that ahu burial was restricted to one particular cultural tradition, or population group." (P. 464.) I gather from the rest of the addendum that since cremation burials existed in the Middle and possibly in the Early periods, and since he states that cremation burials are non-Polynesian, he is implying that those people who practiced cremation burials were not Polynesian. I cannot, unfortunately, accept this point of view until we have skeletal remains from the Early period to analyze. It is well known, as my colleague Dr. Elden Johnson has pointed out to me regarding mound burials, that types of burial can vary within one mound and such variation does not necessarily mean the existence of different populations. On Easter Island certain types of burial may have been restricted to certain social classes within the same population. The evidence from physical anthropology shows that the Easter Island physical type of the Middle

84


and Late periods is definitely Polynesian. Skeletal remains from the Early period of Easter Island are not yet at hand. When they have been excavated and analyzed, I, for one, will be very much surprised if they are not Polynesian in physical type. The evi-

dence from linguistics, ethnology, and archaeology, which of course should not be omitted, indicates that the Easter Island culture is Polynesian, and that the Easter Islanders may have come from the Marquesas Islands in Polynesia.
