Rift Valley Created by Tectonic Event - Findings of Early Man Fortuitous

The birthplace of Mankind is believed to be the Rift Valley in East Africa. It was thought that the valley formed over a long period of time. James Cook University scientists in Australia have found that a tectonic event changed the flow of the Congo, Nile and other rivers thus creating the Ethiopian-Kenyan eastern segment, and the Ugandan-Malawi western branch.

Formerly the assumption was that this didn't happen at the same time. The eastern section developed up to 25 million years before the western segment. This was the prevailing theory.

The Australian evidence indicates that the tectonic event created the eastern and western branches at much the same time. Climate change models will now have to be reviewed.

Because the region is rich in fossils ongoing investigation occurs there. It is the only late Oligocene terrestrial fossil deposit in Africa below the equator. Though fossils of early Man have been found there, it may not be the actual birthplace of Mankind. If could just be fortuitous that evidence has been found there.
