Just Curious

Is it the researchers of evolution who seem to be almost totally interested in only one topic: women's bodies and how women walk or don't walk and which types of women men might want to mate with? Or is it the popularizers who do this?

I'm not a zoologist, but the focus on women's properties suggests that these researchers think men are the sex which does the choosing. Yet in most of the evolutionary psychology literature I've read the argument is that prehistoric women did the picking. Or is it whatever is most convenient?
