A Scientific American interview with famed primatologist and evolutionary theorist Sarah Blaffer Hrdy.

“If we really want to raise Darwin’s consciousness we need to expand evolutionary perspectives to include the Darwinian selection pressures on mothers and on infants.

Well, does that mean that females don’t have brains?”
