Anthropologist Herman Pontzer spends time living among a Hadza hunter-gatherer tribe in order to see if they burn more calories than a typical Westerner. Herman Pontzer, professor of anthropology at Hunter College in New York, investigates the human and ape evolution. His work incorporates laboratory and field studies of humans and apes, living and extinct, to shed light on our evolutionary past. Most recently Dr. Pontzer has investigated energy expenditure among Hadza hunter-gatherers in northern Tanzania. Follow him @HermanPontzer.
