Christina Warinner explores recent changes in human diet, from 50,000 years ago to the present, and discusses how these changes have fundamentally affected human biology, ecology, and societies. This lecture is part of the program ""Ancient Diets"" featuring presentations by Christina Warinner and Zeray Alemseged on how modern human behavior, ranging from tool use to cooking to agriculture to industrial food processing, has allowed us colonize virtually every environment on earth – and even parts of outer space. “Exploring Ancient Diets"" featured presentations by Christina Warinner and Zeray Alemseged and was presented at the California Academy of Sciences on 12/3/2013 as part of The Leakey Foundation’s Speaker Series on Human Origins in partnership with the California Academy of Sciences.
