Most barefoot runners know Daniel Lieberman from Chris McDougall’s best-seller, Born To Run.

Dr. Lieberman is a professor of Evolutionary Biology at Harvard who has done some seminal research on barefoot running. One of his basic premises, from an evolutionary perspective, is that human’s ability to sweat allowed us to run for long distances, letting us track down prey that overheats and tires out.

While Dr. Lieberman is used to big deal academic situations, here he is on The Colbert Report.
