“National Geographic Explorer and Pulitzer Prize-winning journalist Paul Salopek is walking across four continents, retracing the groundbreaking trails blazed by humans who first migrated out of Africa some 60,000 to 120,000 years ago and eventually reached South America. This continuous, multiyear 38,000-kilometer trek began in Ethiopia — our evolutionary „Eden“ — in January 2013, and will end in Tierra del Fuego at the southern tip of South America, a region that helped shape Charles Darwin’s ideas on evolutionary theory.“ (https://outofedenwalk.nationalgeographic.org, Dec.11,2025.)
