Amanda Marcotte on Pandagon: “PZ Myers has a really cool blog post up now about a new theory of menstruation put out in a paper by Emera, Romero, and Wagner, who appear to be actual biologists…. It’s one of those things I want to flag for feminists particularly, because I think really understanding the scientific discourse around human female biology can go a long way to chilling some of the uglier debates that go on about ‘nature’ and things like reproduction, menstruation, etc.”
