If we look at the dates of fossils we do find that the Americas and Australia had humans last.

We also see this among animals that evolved to evade humans (in Africa and to some extent Eurasia) and those that didn't - in the Americas and Australia.

Also genetically we are one species down to the genetic level. But the MOST divergent people, genetically speaking, are the Khoi-San (Bushmen) -- they are genetically more distinct from West Africans than those West Africans are from Irish people

The "Out of Africa" hypothesis seems valid so far - note that this means NOTHING in terms of modern-day peoples.

It seems valid so far and is probably true. But there ae weird evidences of human early migration that may.. May not line up. I doubt any major changes in the theories but I don’t think it’s fully settled
