It's entirely, and frighteningly, plausible that women are diverging in height because they are not eating enough during their teen years.
Eh, no, not plausible. Go to any high school and look at the girls, see how many malnourished to the point of stunted growth you'll find.
I am also pretty sure that by late teens IQ is set and undereating will not affect it.
Go to any high school and look at the girls
I'd guess you'd see very different things in certain high schools than in others.
