  • For decades, researchers have speculated that three now-dry north African waterways once served as paths for the ancestors. Now, Tom Coulthard of the University of Hull in UK and colleagues have modeled the region as it was 100,000 years ago, to see how the monsoon rains flowed across the landscape. After accounting for evaporation and ground absorption, they found the water would have carved three large rivers through the desert, leading north. Two rivers ran along the east of the continent, through much of modern-day Libya. The third, the Irharhar, lay far to the west, in Algeria.
