In early 2013, National Geographic Explorer Paul Salopek began an epic walk, following the path of the first human migration out of Africa about 60,000 years ago.

It’s an observation as old as humans gathering around campfires: Light at night can draw an erratically circling crowd of insects. In art, music and literature, this spectacle is an enduring metaphor for dangerous but irresistible attractions. And watching their frenetic movements really gives the sense that something is wrong — that instead of finding food and evading predators, these nocturnal pilots are trapped by a light.

The World's hosts Marco Werman and Carolyn Beeler talked with National Geographic Explorer Paul Salopek about his experiences walking across China and beyond as a part of his "Out of Eden Walk" project.
