As Paul Salopek journeys around the world on foot, he will follow the migration pathways of our ancestors who walked out of Africa 50,000 years ago.

Meet Paul Salopek

Meet two-time Pulitzer Prize winner Paul Salopek, a National Geographic fellow and Pulitzer Center grantee who will begin a trek around the world in winter 2013. His "Out of Eden" walk, which will follow the path of human migration out of Africa, will span 39 countries and take approximately seven years.
