Preface
This volume contains revised papers from a 1982 Wenner-Gren-sponsored symposium utilizing data from human skeletal analysis and paleopathology to measure the impact on human health of the Neolithic Revolution and antecedent changes in prehistoric hunter-gatherer food economies. The symposium developed out of our perception that many widely debated theories about the origins of agriculture had testable but untested implications concerning human health and nutrition and our belief that recent advances in techniques of skeletal analysis, and the recent explosive increase in data available in this field, permitted valid tests of many of these propositions. We asked specialists to prepare syntheses of archaeological and skeletal data comparing the health of prehistoric human populations before, during, and after the Neolithic Revolution in different parts of the world. Because we were interested in generalizations about processes of cultural evolution and their impact on human life, rather than merely in local archaeological sequences per se, the conference and this volume were arranged in a format of 'controlled comparison in which regional sequences are prepared and presented in a manner parallel to one another as much as posible to facilitate comparative analysis. This format was designed to facilitate identification of health trends common to the various world regions or to recognizable subsets of these regions. This volume is the first such synthesis of paleopathological data from around the world focusing on changing patterns of health among human populations rather than the diagnosis of particular pathologies or the interpretation of the history of specific diseases. It also represents the first attempt to apply these data to the testing of theories of culture change other than at the local level In the studies presented, a number of common patterns emerge with sufficient clarity to provide striking answers to severa1210ng-debatedquestions concerning the impact of this one major technological revolution on human health. The conclusions that we have drawn are discussed in our own final chapter while an independent analysis is offered by Anna Roosevelt. The individual regional chapters that make up the bulk of the volume, and which cover essentially all regions of the world for which reasonably good data could be obtained, provide an up-to-date synthesis of existing data on changes in human health associated with the transition.

PREFACE
provide a data set from which other investigators can test their own theories or evaluate our conclusions independently and state-of-the-art examples of the application of recently developed techniques in skeletal analysis and paleopathology The language of these applications has been standardized insofar as possible to facilitate easy comprehension and comparison. An introductory chapter by Goodman et al. provides a nontechnical summation of the techniques utilized and the pathologies commonly discussed. Chapter bibliographies direct the reader to more technical descriptions of research techniques as well as more complete presentations of regional data. The book is designed primarily as a reference and sourcebook for scholars and students in the fields of economic and ecological prehistory skeletal analysis, and paleopathology However, the book addresses issues concerning the impact of progress and civilization that have been of broad scholarly and popular interest at least since the writings of Hobbes Rousseau, and Francis Bacon. Moreover, because it is necessary that the data from skeletal analysis be comprehensible to nonspecialists if those data are to be used to test theories of culture change, and because it is necessary for individual archaeological sequences to be comprehended easily by prehistorians working in different regions we have put a great deal of editorial effort into making each contribution readily comprehensible by a reader with only a modest background and with a general interest in the issues discussed. As such, the book should be of value and interest not only to professionals and students in immediately related fields but also to a range of laymen, students and professionals interested in a host of related fields. history and medical history subsistence economics, culture change, nutrition, epidemiology the philosophy of science, and the history of technology The conference on which the book is based was held at the Valcour Conference Center of the State University of New York College at Plattsburgh and was sponsored jointly by the Wenner-Gren Foundation for Anthropological Research and the Hudson Symposium Fund of SUNY College at Plattsburgh. We wish to thank Dean Charles Warren and Acting Dean Houng Liu, Mr Robert Moll, Ms Bette Brohel, Mrs. Katie Covey and Mrs. Jamesena Moore as well as the faculty and students of the Department of Anthropology SUNY College at Plattsburgh, for their assistance in running the conference.

Upper P a l e o l i t h i c through t h e Neolithic. The trend appears t o be more strongly manifest i n the female sample than in t h e male sample. However, none of t h e subsarnples show a s i g n i f i c a n t decrease from t h e Upper P a l e o l i t h i c t o t h e Mesolithic. There is a s i g n i f i c a n t decrease from the Mesolithic t o t h e Neolithic i n t h e o v e r a l l and female samples. The female subsample i s defining the trend. Within individual time periods t h e only s i g n i f i c a n t r e s u l t i s t h e decrease i n female s t a t u r e during t h e Upper P a l e o l i t h i c . For t h e Neolithic we suspect a manifest c u r v i l i n e a r p a t t e r n , a trend toward decreasing s t a t u r e from t h e Upper P a l e o l i t h i c t o the Neolithic b e i n g replaced by increasing s t a t u r e within t h e Neolithic. This can be t e s t e d only by adding t o our sample f o r Neolithic and post-Neolithic time periods. A t t h i s point we conclude t h a t there i s s i g n i f i c a n t s t a t u r e d e c l i n e from the Upper P a l e o l i t h i c through t h e Neolithic, with p o s s i b l e reversal from t h a t point onwards, i n agreement with ~ r a ~ (1980) e r and Key (1980).
