Humans and our recent ancestors have been accomplished endurance runners for more than a million years. Our evolutionary history as runners partly accounts for why aerobic exercise is such a key component of human health. In this talk, recorded in July 2016, Daniel Lieberman explores how and why the human body evolved to run long distances. Daniel Lieberman is the Professor and Chair of the Department of Human Evolutionary Biology, and the Edwin M. Lerner II Professor of Biological Sciences at Harvard University. He is a member of the Scientific Executive Committee of The Leakey Foundation. His research is on how and why the human body is the way it is, with particular foci on the origins of bipedalism, how humans became endurance runners, and the evolution of the highly unusual human head. Lieberman has published 3 books and more than 100 articles. His latest books are The Evolution of the Human Head, and The Story of the Human Body.
