I've seen a few researchers say that they thought that Sasquatch is an evolutionary link between the great apes and humans. Picture a few hundred thousand years ago when large apes in Europe and North America began to evolve.....walking upright, increasing intelligence, beneficial traits being passed on through selective breeding. It wouldn't take many generations to have a Sasquatch type creature. Give those Sasquatch a few generations of evolution and you progress to neanderthal, et al.
Meanwhile in Africa, part of the large apes began to evolve.....kinda. They started walking upright.....sorta. They became smarter......marginally. Their main evolutionary jump was losing most of the fur which covered their body to deal better with the heat. There was no passing of beneficial genetics through selective mating because the brains had not yet developed past the point of animalistic urges. These creatures simply mated with anything that would stay still long enough......basically the "shotgun approach" to having at least one surviving offspring. These creatures ceased to evolve any further.....stopping just short of reaching the same evolutionary level as bigfoot.
Now we call them niggers.
