How Humans Evolved remains the most up-to-date, forward-looking book in physical anthropology. Through a unique and balanced blend of evolutionary theory, population genetics, and behavioral ecology, the authors move beyond merely describing anthropological finds to showing students the big picture about how humans lived in the past and why they have evolved into the people they are today. The fully revised and updated Sixth Edition offers the best of current research, including important new coverage of Ardipithecus, the Neanderthal genome, early complex tool-making and symbolic behavior, and much more.
