Shortest colonization routes from East Africa (Addis Ababa) along landmasses and high mountain ranges (areas with average elevation >2,000 m) to the populations from the CEPH human genetic–diversity panel. Small blue dots represent populations, the hypothetical origin of modern humans is represented as a large red dot, colonization routes are shown in red, and uncrossable areas with average altitude >2,000 m are brown.
