@Witch_Hunter_Siegfired @justnormalkorean @wingedhussar @SpurgAnon @lonestarr @Xenophon The theory of evolution itself naturally leads to a view of a difference in races. It's founding book is usually called On the Origin of Species, but it's full title is:
On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

It doesn't even matter if they assert we were all living in Africa 10,000 years ago or not, because evolution would automatically mean we adapt to different environments and gain different abilities from it, which automatically means biological differences in intelligence and behavior. The only thing that the Out Of Africa Theory (lie) changes is the pace of the DNA change, which is still too slow for us to have any impact short of a 500 year long eugenics campaign which is not allowed anyways. Evolution automatically means racial differences that can't be changed by education.
