Europe is mostly white because it is colder up there and any invaders from the south who hate Europeans for being white and settle in Europe can look forward to eventually having white descendants. the original settlers of Europe who moved north from the middle east probably moved there during the ice age when it was much colder and everyone was white because of the colder climate.
in other news, the earth moves closer to the sun every year because of gravity and the temps get warmer every year because of that. so eventually we will all get darker and die from the heat.
climate change is a hoax and a lie and a scam.
they just want your money.
also, the neanderthals died out in Europe because they were vegans....
