Kevin D. Hunt is Professor of Animal Behaviour and Anthropology in the Department of Anthropology at Indiana University, Bloomington. He is also Founder and Director of the Semliki Chimpanzee Project, which was established in 1996 to study and preserve the chimpanzees within the Toro-Semliki Wildlife Reserve. Broadly trained in various anthropological disciplines, much of Professor Hunt's published work has centred on functional morphology and what chimpanzee locomotion, posture and ecology can tell us about what led humans to diverge from apes, and what advantage bipedalism gave our chimpanzee-like ancestors roughly five million years ago.
