           | The bigger problem is I don't think your numbers are right,
           | Neanderthals had notably larger brains than us. Via
           | wikipedia:
           | 
           | Average Neanderthal male height: 165cm Average Neanderthal
           | male brain volume: 1600cm^3
           | 
           | Average pre-industrial human male height: 165cm Average pre-
           | industrial human male brain volume: 1260cm^3
           | 
           | The difference is that Neanderthals also had
           | disproportionately larger _eyes_ than us, yet probably
           | similar visual acuity: their brains had more pixels to
           | process, which takes up quite a bit of volume. In fact it 's
           | _eye size_ which seems to be the biggest confounding variable
           | in associating brain size with intelligence. Their cerebellum
           | was actually smaller than ours, which is probably more
           | relevant - but who knows?
