Beginning my ethnographic work with hunter-gatherers I assumed that most distinctive human features evolved as a consequence of ancestral females pairing with hunting males to form nuclear families with men provisioning their wives and dependent offspring. Challenges to that “hunting hypothesis” have mounted in paleoanthropology and archaeology, but it was behavioral findings that forced my own paradigm shift. I’ll review some of those findings, including evidence of the important role of grandmothers, and some life history comparisons between humans and chimpanzees."
Kristen Hawkes is Distinguished Professor of Anthropology at the University of Utah. Her ethnographic projects with hunter-gatherers investigate sex and age differences in foraging strategies to improve hypotheses about human evolution. The importance of grandmothers' help for youngsters when their mothers have newborns focused her attention on the evolution of human longevity, and prompted continuing comparisons of human and chimpanzee life history. She is a member of the National Academy of Sciences, The American Academy of Arts and Sciences, and the Scientific Executive Committee of the Leakey Foundation.
