I don't endorse Harris's theory as much as I don't know of the
competing theories very well. The point was that sexual selection can
play a role, unlike as in ("bad") sociobiology.

right. It is likely a "combo." Further, cultural differences can
encourage biological differences. (African males' fascination with the
female butt might encourage females to develop larger butts, etc.)
