"Scientists have found relatively few weapons belonging to Neanderthals, Slimak wrote. However, Neanderthals were 'excellent artisans,' making tools; with 'a creativity that is beyond us.' But this creativity was not enough to outwit humans' regimented weapon making, which ultimately led to Neanderthals'; extinction, according to Slimak. That's because the 'modern humans who colonized Europe produced weapons that were both more numerous and more; effective,' he wrote. Humans' insistence on standardization led to uniform flints, and Neanderthals' originality couldn’t compete."; So Neanderthals were taken out by OCD?
