Humans diverged into separate populations for 100,000 years

Ancient humans started down the path of evolving into two separate species before merging back into a single population, a genetic study suggests.

The genetic split in Africa resulted in distinct populations that lived in isolation for as much as 100,000 years, the scientists say.

This could have been caused by arid conditions driving a wedge between humans in eastern and southern Africa.

Details have been published in the American Journal of Human Genetics.

It would be the longest period for which modern human populations have been isolated from one another.
