This article suggests, based in new or newly viewed material, that women may have been hunters along with the men, are responsible for most of the cave art, and left the tribe at times to find new mates.

Cave art: much of it is hand stencils, and many of these apparently point to a woman's size in hands.

Hunting: female artists paining hunting combined with the many fractures and other damages in female skeletons as well as in men's.

Some going out to find new partners to prevent inbreeding, new technique ( I think it was new) points towards this being the women.

The last one I doubt, and I cannot find out if it is speculations, or based on anything substantial.

Gettler says that the shorter interbirth interval and the long period of child rearing characteristic in modern humans could have only happened with ancient dads lending a hand.

What do you think? Can this be true, and if yes, does it have any influence on how we percieve ourselves today?
