Why did humans become such efficient long-distance runners? How can runners avoid injury? Daniel Lieberman explores how the human body evolved to run. The Leakey Foundation presents Being Human, a live event mixing short talks from great minds with fun hands-on experiments, drinks, conversation and storytelling. Each event investigates different aspects of our evolution, our behavior, and the human experience.
