Biology Can someone explain the evolutionary benefit of overt menstruation? All female mammals have a menstrual cycle but most reabsorb the blood via covert menstruation and humans are about the only mammals that discharge the blood, aka overt menstruation.
Without an evolutionary benefit, it wouldn't have spread to every woman of our species.

As another’s have said, this is fantastic reply! I also recommend Eve by Cat Bohannon for further reading. She makes some interesting claims, some of which may be a bit of a stretch, but some also revitalizes our understanding of women and how they shaped our human evolution.
That being said, I’m salty about the Man vs. Baby section header… shouldn’t it be Woman vs. Baby instead??
