Why did the Homo sapiens survive and the Neanderthals didn’t? Scientists now believe the Neanderthals’ large eyes may be to blame. Indeed, analysis of Neanderthal skulls shows that they had much larger eye sockets than the Homo Sapiens. This, in turn, meas they used most of their brain for seeing, instead of thinking, making them slower to adapt to changes in the environment when the Ice Age came.
