Tracing the evolution of the human diet from our earliest ancestors can lead to a better understanding of human adaptation in the past. It may also offer clues to the origin of many health problems we currently face, such as obesity and chronic disease. This fascinating series of talks focuses on the changing diets of our ancestors and what role these dietary transitions played in the evolution of humans. Here Mary C. Stiner (Univ of Arizona) discusses Archaic Human Diets followed by Alyssa Crittenden (Univ of Nevada, Las Vegas) on Current Hunter-Gatherer Diets and Steven Leigh (Univ of Illinois at Urbana-Champaign) on Diets and Microbes in Primates.
