Research in the Department of Evolutionary Anthropology focuses on the evolutionary history of the mammalian radiation containing the human species and on the origins of human nature. By being taxon-based, evolutionary anthropology is inherently interdisciplinary, and brings techniques and concepts from a variety of traditional academic disciplines to bear on the core questions of who we are and where we came from. These disciplines include evolutionary biology, archaeology, geology, paleontology, behavioral ecology, genetics, developmental biology, psychology, economics and other social sciences.
