I love it when

evo-psych proves to be a lot of old hooey.

Pharyngula: "Years and years of studies by scientists trying to explain women’s behavior by their hormonal fluctuations are gradually falling apart. We’ve heard so many inconsistent, contradictory tales of how fertility/menstruation turns women into unconscious breeders or nurturing mothers, how women are driven to ‘hypogamy’ by their evolutionary instincts (that’s a big one with the MRAs), and how mate choices wobble from alpha to beta over the course of a month" - all rot.
