Neanderthal extinction revised

Instead they were wiped out by demographic factors, namely small population size and inbreeding. Modern humans helped out by essentially serving as a sort of “sexual distraction,” so then when Neanderthals mated with modern humans the gene flow went to modern human populations rather than Neanderthal populations, ie we swamped them and assimilated them with little conflict involved, and thereby accelerated a process that would’ve eventually killed them all of anyways.
