I would suspect that physical looks/features would throw a wrench into this - or at least correct things a bit.

- trhway 12y agoyep, until gap becomes too big so the species divergence begins as physical looks/features play role for both processes - help keep a species together as well as to help distinguish between subspecies once the divergence has started thus speeding up the divergence.
- peripitea 12y agoI don't follow. How would that affect this phenomenon? Given that the cited correlation refers strictly to intelligence, looks (and for that matter, all other factors) are presumably already accounted for.
- fossuser 12y agoIt was more a response to the parent comment. I was suggesting that an intelligent person may choose a mate that's less intelligent because they're prettier which would help resist some of the divergence. They mention assortative mating is greater for intelligence compared to physical aspects like height and weight, but 'prettiness' is a more subjective harder to quantify measure that I would guess plays a larger role in mate selection than just height and weight. This is ignoring the fact that height and weight are probably opposite anyway (women wanting taller men, men wanting shorter women) - so there are some issues there too.
