    Fun fact when Homo Sapiens migrated out of Africa it also experienced a genetic bottleneck since the group that left Africa was small in numbers. We can even see it in our DNA. Compare the DNA of a person with East Asian genes to the DNA of a Western European and you will find a higher percentage of similarities, than when you compare a West African’s DNA to that of an East African. Africa is genetically the most diverse region on the planet. Even though early Europeans mixed with the Neanderthals.

      It amazes me how little population migration there has been in africa. Discrete groups remain isolated from each other for tens or even hundreds of thousands of years. Everywhere else, population migrations and genetic mixing has occured regularly.
