    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.

      sounds like inbreeding is…good? j/k I mean most of Africa (without western influence) is nearly millenniums behind in true technological development, but one could argue the reverse is also true right? Look at what we’ve done to the planet. I’m sure no one would say we’ve advance in a true positive impact to the planet.

        plot twist…or maybe not so much, but planet of the apes is actually a real future vision.

      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.

        All because of fear…we kill then ask questions later…so that keeps migration down. I mean even till this day you’d think we’re more enlightened…nope! Let’s get ICE and get those immigrants cause they are all rapist and murderers.

        Probably because Africa is very hard to cross on foot. There is a desert up north and a very dense jungle in the middle surrounded by savannahs and rivers full of dangerous animals. Also probably hunter gatherers in Africa had it pretty good because of the abundant flora and fauna, so there was no need to trek far. So the only people that mixed with others were sea faring tribes or came in contact with sea faring traders. Like Madagascar people have Austronesian genes in their DNA and even their languages falls under the Austronesian family.
