Um, all the most modern research indicates that women have by far the higher tolerance of pain. And even without these studies, have you ever seen the video of men trying out birth simulators or period pain simulators? They are losing their minds with things that women deal with routinely.

There is no archeological evidence of pervasive violence prior to 13k years ago and most of it is from about 8k years ago, so I'm not buying the evolutionary theory.
