wonder if anyone has ever considered that it may have been disease that wiped out neanderthals?
Yes, the idea has been tossed around. Perhaps a pandemic type event drastically reduced their numbers, and the now isolated pockets of Neanderthals that remained just slowly vanished over time, since the environment was radically changing around them, and H. sapiens coming north would have added pressure to the groups when competing for food, shelter and resources.
Yeah..Liberalism. They adopted the "zero-population growth" stance.
