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.

Discusses the scientific research which led to the theories of human origian, including the contributions of Charles Darwin, Thomas Henry Huxley, and Louis Leakey.

Humans are unquestionably the dominant animal. Why, then, are we creating a world that threatens our own species? Two renowned scientists tackle the fundamental challenge of the human predicament and offer a vivid and unique exploration of humanity's origins, evolution, and its potential future.

The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture. The Earth's geological record suggests that some evolutionary events were coincident with substantial changes in African and Eurasian climate, raising the possibility that critical junctures in human evolution and behavioral development may have been affected by the environmental characteristics of the areas where hominins evolved. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. Improved climate records for specific regions will be required before it is possible to evaluate how critical resources for hominins, especially water and vegetation, would have been distributed on the landscape during key intervals of hominin history. Existing records contain substantial temporal gaps. The book's initiatives are presented in two major research themes: first, determining the impacts of climate change and climate variability on human evolution and dispersal; and second, integrating climate modeling, environmental records, and biotic responses. Understanding Climate's Change on Human Evolution suggests a new scientific program for international climate and human evolution studies that involve an exploration initiative to locate new fossil sites and to broaden the geographic and temporal sampling of the fossil and archeological record; a comprehensive and integrative scientific drilling program in lakes, lake bed outcrops, and ocean basins surrounding the regions where hominins evolved and a major investment in climate modeling experiments for key time intervals and regions that are critical to understanding human evolution.

Interrogating Human Origins encourages new critical engagements with the study of human origins, broadening the range of approaches to bring in postcolonial theories, and begin to explore the decolonisation of this complex topic. The collection of chapters presented in this volume creates spaces for expansion of critical and unexpected conversations about human origins research. Authors from a variety of disciplines and research backgrounds, many of whom have strayed beyond their usual disciplinary boundaries to offer their unique perspectives, all circle around the big questions of what it means to be and become human. Embracing and encouraging diversity is a recognition of the deep complexities of human existence in the past and the present, and it is vital to critical scholarship on this topic. This book constitutes a starting point for increased interrogation of the important and wide-ranging field of research into human origins. It will be of interest to scholars across multiple disciplines, and particularly to those seeking to understand our ancient past through a more diverse lens.

The Primate Origins of Human Nature (Volume 3 in The Foundations of Human Biology series) blends several elements from evolutionary biology as applied to primate behavioral ecology and primate psychology, classical physical anthropology and evolutionary psychology of humans. However, unlike similar books, it strives to define the human species relative to our living and extinct relatives, and thus highlights uniquely derived human features. The book features a truly multi-disciplinary, multi-theory, and comparative species approach to subjects not usually presented in textbooks focused on humans, such as the evolution of culture, life history, parenting, and social organization.

Why do we behave the way we do? Biologist Paul Ehrlich suggests that although people share a common genetic code, these genes "do not shout commands at us...at the very most, they whisper suggestions." He argues that human nature is not so much result of genetic coding; rather, it is heavily influenced by cultural conditioning and environmental factors. With personal anecdotes, a well-written narrative, and clear examples, Human Natures is a major work of synthesis and scholarship as well as a valuable primer on genetics and evolution that makes complex scientific concepts accessible to lay readers.
