Neanderthal extinction linked to large eyes
A study of Neanderthal skulls suggests that they became extinct because they had larger eyes than our species.
It is thought that more of their brain was devoted to seeing in the long, dark nights in Europe, at the expense of high-level processing.
Co-author of the study published in Proceedings of the Royal Society B Journal, Chris Stringer, explains why our smaller eyes helped us survive.
