Divergence of Eurasian and African population 100000 years ago.

New research supports the probability of the divergence of Eurasians and Africans was 100000 years ago.

Our joint analysis of data from African, European, and Asian populations yielded new dates for when these populations diverged. In particular, we found that African and Eurasian populations diverged around 100,000 years ago. This is earlier than other genetic studies suggest, because our model includes the effects of migration, which we found to be important for reproducing observed patterns of variation in the data.
