Races are a social construct, and if you don't believe that, you're evil. Oh, and remember: common ancestor 55k years ago. No talk that the study comes out with 350,000 years. Definitely get over the talk that races are de facto genetic components inherited from hybridization with hominids. That different populations have DNA fragments specific only to themselves, mutating separately relative to the rest of humans for 800k - 1.5million years? That Europeans have practically no hominid genes - because Neanderthals have the least, and the DNA of the 'colorful archaic family' is completely absent in them? Stupidity! According to the mainstream, 3,000 years ago we were black: "Until 3,000 years ago, most Europeans had dark skin" [history.interia.pl]. After all, you can see in the picture, it's been 200 years, and the blonde is indeed 10% of the way to native to Australia "skin color". Aborigines didn't cast metals because they didn't need to. There are no races! The Negro in the ad with the White woman.
