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.

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.

Leaping Ahead: Advances in Prosimian Biology presents a summary of the state of prosimian biology as we move into the second decade of the 21st century. The book covers a wide range of topics, from assessments of diversity and evolutionary scenarios, through ecophysiology, cognition, behavioral and sensory ecology, to the conservation and survival prospects of this extraordinary and diverse group of mammals. The collection was inspired by an international conference in Ithala, KwaZulu-Natal, South Africa in 2007, where prosimian biologists gathered from Canada, Finland, France, Germany, India, Italy, Japan, Madagascar, South Africa, Tanzania, the United Kingdom, and the United States of America. The meeting reverberated with the passion prosimian researchers feel for their study subjects and with their deep concern for the future of prosimians in the face of ongoing habitat destruction and the burgeoning threat of bushmeat hunting. Chapters for this volume were contributed by researchers from across the globe; they attest to the diversity, vibrancy and rapid growth of prosimian biology, and to the intellectual advances that have revolutionized this field in recent years. Since its earliest beginnings, prosimian research and its resultant literature have had a strong francophone component, and researchers in many prosimian habitat countries are more comfortable reading and writing in French rather than English. French summaries of all chapters have been included. The volume is targeted at researchers, both those entering the field and established scientists, who have an interest in the biology of primates and small mammals. It is also aimed at conservation biologists seeking a deeper understanding of the faunas and conservation developments in Africa, Madagascar and Southeast Asia, and anyone who has an interest in discovering the true diversity of our order, the Primates.
