These original contributions on the evolution of primates and the techniques for studying the subject cover an enormous range of material and incorporate the work of specialists from many different fields, showing the necessity of a multidisciplinary approach to problems of primate morphology and phylogeny. Collectively, they demonstrate the concerns and methods of leading contemporary workers in this and related fields. Each contributor shows his way of attacking fundamental problems of evolutionary primatology.The range of findings in this book include new clues to the evolution of the middle ear and the subsistence behavior of early primates, a persuasive critique of the Smith-Jones hypothesis that many features of primate cranial morphology are adaptations to the special vicissitudes of arboreal habitation, the remarkable association of relative muscle mass in the hands and feet of catarrhine primates with the particularities of prehensile behaviors, the wealth of behavioral data that may be obtained by the concentrated study of certain primates in the vicinity of waterholes, the striking differences between inferences about the same behavioral phenomena that are based on long-term as opposed to short-term observations of one primate social group, and the strategy of sophisticated mathematical techniques for elucidating biomechanical, evolutionary, and behavioral problems.Each chapter conveys the status and progress of research in these and other particular areas of special interest, pointing the way toward further clarification of the functional biology and phylogeny of primates through the application of relatively new techniques or the comprehensive employment of available methods. No attempt is made to smooth over controversial points of view, or to endorse a single uniform model of primate evolution. This work will be an important reference for evolutionary and physical anthropologists, evolutionary biologists, comparative morphologists, human anatomists, behavioralists, and students of evolution.

Advances in fossil studies relating to the origin of Homo sapiens have strengthened the hypothesis that our direct ancestors originated on the African continent. Most researchers also agree that the time when prehumans diverged from the last common ancestor was in the early part of the Late Miocene epoch. Focus must now shift from determining the times and places of hominid origins to clarifying hominid evolutionary problems, such as the selective factors and acquisition processes of hominid bipedalism. In March of 2003, researchers from Africa, Europe, Japan and the United States convened in Kyoto for a symposium on Human Origins and Environmental Backgrounds, an interdisciplinary effort to consider these evolutionary puzzles, to report current research and to exchange thoughts towards better understanding the relationship among environmental changes, adaptive mechanisms and human origins. This book is the result of that symposium, and includes a diverse and unique set of papers on topics such as hominid evolution, dispersal and morphology, and the origins of bipedalism.

It is often said that to understand Plato we must understand his times. Many readers who might accept without question this saying of historical criticism may still wonder why we should think it necessary to begin our enquiry as far back as Homer and beyond. In the case of Plato there is an even greater need to pursue the argument back to the very beginnings of the historical period in which he lived and worked.It is quite impossible to understand the genesis of Plato's ideas without understanding the profound change that Greek society underwent in the post-Homeric period that preceded him. This change in social structure created a mercantile, progressive Greek society, one which laid the foundations for all the subsequent history of Europe and the West. The Genesis of Plato's Thought is particularly highly regarded because it departs vigorously from the traditional abstract, static view of Plato's thought.Winspear's volume on Plato's thought traces, in a realistic fashion, the deep-reaching social and economic roots of Plato's concept of the state and society. Winspear believes that nowhere can the social roots of philosophy be more sharply seen and more firmly apprehended than when one is dealing with the origins of Western philosophy among the Greeks. His book contains the body of information which any reader should have if they wish to approach Plato as a historical figure. To make the book useful to a wide circle of readers, brief biographical identifications for the various important figures of Greek life are introduced in the text.
