I'd like to tell everyone about a new paper (highlighted in Science) which destroys the myth that men were hunters and women were gatherers, and that this impacted on brains & evolution
a big review of anthropological studies around the world shows that women hunt in nearly 80% of the societies studied

I think this gives a strong argument against any claims that there are 'lady brains' because the women had to stay at home and gather. And against any claims that modern gender roles have any origins in evolution.
