Early Homo sapiens, known from fossils found at Omo and Herto in Ethiopia, began making stone tools in the Nile Valley of Egypt some 150,000 years ago. Previous studies have traced their path out of Africa through Sinai to the Levant. New research reveals a second, more southerly route through Arabia, where modern human populations lingered for some 50,000 years before migrating north to the Levant. There they interbred with Neanderthals—and perhaps borrowed some of their tool-making techniques.
