Retracing the first human migration

A journey of 38,000-kilometers begins with a single step. 12 years ago this month, journalist Paul Salopek set off on a journey that follows the first human migration out of Africa, starting in the great Rift Valley in Ethiopia where the first human fossils were found with plans to end at Tierra del Fuego at the Southern Tip of South America. He calls the journey the "Out of Eden" walk with the support of the Nation Geographic Society. He sends dispatches from the road that tell the story of each place he goes. He speaks to Jesse today from somewhere in Japan.
