Perhaps I will when I have time later. One thing I found fascinating about Catching Fire was the author's assertion that gender roles sprang from the need for protection in camp, as cooking requires (a) a fire that's easy to detect, and (b) sitting in one place for a ling time. Essentially, men and women struck a "deal" in which women cook for men and men protect them while doing so, and that this relationship has exactly nothing to do with sex. Best argument I've ever read, frankly.
And the African tribe that marries off the young bucks to the crones because the crones will bloody well be able to cook, which gives the young bucks the opportunity to thrive, outlive their crones and then take on the hot young new wives when they're established. It's funny how many taboos there are to talking about sex, even when the discussion is about the economic motivations derived from gender.
