Early humans left Africa (so they think now) 60K to 90K years ago. They became Europeans, Asians, Middle-Easterners, Australians, Americans. This after traveling thousands of miles away from Africa and adapting to new climates, new lands, new waters.
Africans, staying in place for those thousands of years, never invented the wheel. When European explorers went to the interior of Africa, they found no wheels, and little to no advancement beyond the Stone Age.
Why?
