This new edition of Biological Anthropology is evolutionary in perspective in the belief that evolution is the only unifying theory that can clearly explain the existing array of biological and cultural data. Students learn the basics of anthropological theory and human genetics before covering the topics of vertebrate evolution, primate evolution and social behavior, human evolution and behavior, and human variation and adaptation. In each section, behavior, morphology, adaptation, and ecology are discussed to provide the comparative basis for human origins.
