Human Frontal Cortex Did Not Evolve Fast Relative To Other Brain Regions

The commonly-held belief that human brain evolution was driven by large frontal lobes is a myth, an anthropological study has found.

The superiority of human intelligence isn’t due mainly to the large size of the front part of our brain — contrary to decades of scientific thinking, say scientists.  New research concludes that this brain area, called the frontal lobes, isn’t disproportionately enlarged in humans. So other, supposedly more primitive brain areas may have been just as important.
