Processes In Human Evolution

Updated and rewritten version of first edition, published under title: Human evolution: trails from the past (Oxford biology) / Camilo J. Cela-Conde and Francisco J. Ayala. 2007.

The discoveries of the last decade have brought about a completely revised understanding of human evolution due to the recent advances in genetics, palaeontology, ecology, archaeology, geography, and climate science. Written by two leading authorities in the fields of physical anthropology and molecular evolution, Processes in Human Evolution presents a reconsidered overview of hominid evolution, synthesising data and approaches from a range of inter-disciplinary fields. The authors pay particular attention to population migrations - since these are crucial in understanding the origin and dispersion of the different genera and species in each continent - and to the emergence of the lithic cultures and their impact on the evolution of cognitive capacities. Processes in Human Evolution is intended as a primary textbook for university courses on human evolution, and may also be used as supplementary reading in advanced undergraduate and graduate courses. It is also suitable for a more general audience seeking a readable but up-to-date and inclusive treatment of human origins and evolution.

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.

This book is intended as a comprehensive overview of hominid evolution, synthesising data and approaches from physical anthropology, genetics, archaeology, psychology and philosophy. Human evolution courses are now widespread and this book has the potential to satisfy the requirements of most, particularly at the advanced undergraduate and graduate level. It is based on a translation, albeit with substantial modification, of a successful Spanish language book.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

This volume offers an integrative approach to the application of evolutionary theory in studies of cultural transmission and social evolution and reveals the enormous range of ways in which Darwinian ideas can lead to productive empirical research, the touchstone of any worthwhile theoretical perspective. While many recent works on cultural evolution adopt a specific theoretical framework, such as dual inheritance theory or human behavioral ecology, Pattern and Process in Cultural Evolution emphasizes empirical analysis and includes authors who employ a range of backgrounds and methods to address aspects of culture from an evolutionary perspective. Editor Stephen Shennan has assembled archaeologists, evolutionary theorists, and ethnographers, whose essays cover a broad range of time periods, localities, cultural groups, and artifacts.
