SciCafe: Why Walk on Two Legs? The Pros and Cons of Bipedalism
April 1, 2015
Walking on two legs, or "bipedalism," is a key characteristic defining humans and our early ancestors. But what an odd way to walk and run! Join Museum Curator Brian Richmond and Jeremy DeSilva from Boston University in exploring the great advantages of walking on two legs, as well as the unfortunate consequences of evolving bipedalism from a body plan designed to walk on four, not two, legs.
