The Longest Walk
Homo sapiens set out to discover the Earth some 60,000 years ago, traveling from Ethiopia’s Great Rift Valley to the farthest tip of South America. To retrace the diaspora, writer Paul Salopek has begun his own global journey, a 21,000-mile trek that touches four continents. Calling the project the Out of Eden Walk, Salopek is using the latest fossil and genetic findings to plot his route. A record of his travels is being posted regularly at outofedenwalk.nationalgeographic.com.
