Science in a Minute 103019 Scientists Pinpoint Ancestral Homeland of All Modern Humans

A team of scientists claims to have identified a region in Southern Africa as the birthplace of all modern humans. The researchers say they have evidence that the ancestral home of all living humans was in the Greater Zambezi River basin, which includes Northern Botswana, into Namibia to the west and Zimbabwe to the East. Modern humans are said to have emerged in this region some 200,000 years ago, but changes in Africa’s climate triggered migration from it 110,000 to 130,000 years ago.
