A bold new theory on what sparked the "big bang" of human culture The abrupt emergence of human culture over a stunningly short period continues to be one of the great enigmas of human evolution. This compelling book introduces a bold new theory on this unsolved mystery. Author Richard Klein reexamines the archaeological evidence and brings in new discoveries in the study of the human brain. These studies detail the changes that enabled humans to think and behave in far more sophisticated ways than before, resulting in the incredibly rapid evolution of new skills. Richard Klein has been described as "the premier anthropologist in the country today" by Evolutionary Anthropology. Here, he and coauthor Blake Edgar shed new light on the full story of a truly fascinating period of evolution. Richard G. Klein , PhD (Palo Alto, CA), is a Professor of Anthropology at Stanford University. He is the author of the definitive academic book on the subject of the origins of human culture, The Human Career. Blake Edgar (San Francisco, CA) is the coauthor of the very successful From Lucy to Language, with Dr. Donald Johanson. He has written extensively for Discover, GEO, and numerous other magazines.

"Since its publication in 1989, The Human Career has proved to be an indispensable tool in teaching human origins. This substantially revised third edition retains Richard G. Klein{u2019}s innovative approach while showing how cumulative discoveries and analyses over the past ten years have significantly refined our knowledge of human evolution. Klein chronicles the evolution of people from the earliest primates through the emergence of fully modern humans within the past 200,000 years. His comprehensive treatment stresses recent advances in knowledge, including, for example, ever more abundant evidence that fully modern humans originated in Africa and spread from there, replacing the Neanderthals in Europe and equally archaic people in Asia. With its coverage of both the fossil record and the archaeological record over the 2.5 million years for which both are available, The Human Career demonstrates that human morphology and behavior evolved together. Throughout the book, Klein presents evidence for alternative points of view, but does not hesitate to make his own position clear. In addition to outlining the broad pattern of human evolution, The Human Career details the kinds of data that support it. For the third edition, Klein has added numerous tables and a fresh citation system designed to enhance readability, especially for students. He has also included more than fifty new illustrations to help lay readers grasp the fossils, artifacts, and other discoveries on which specialists rely. With abundant references and hundreds of images, charts, and diagrams, this new edition is unparalleled in its usefulness for teaching human evolution."--Publisher's description.
