THE PATRIARCHY EXPLAINED AS A NATURAL CONSEQUENCE OF SEXUAL DIMORPHISM: Or another of Razib's greatest hits.

I'm three-quarters done with the Judith Rich Harris book that inspired Razib's post, by the way, and it's really great. She's an independant scholar, so she isn't tied down to one field and thus goes all over the scientific map to reason out her view of why people are different. Good good stuff, and paced and organized really well so there's some strong narrative drive to it.
