I agree, evolution works over thousands of generations. We're still only a few generations from the invention of birth control. We still do a lot of things that used to lead to reproduction, but today lead nowhere. Another thing I've noticed is that women tend to prefer a guy of higher social economic status. But if she has done a lot of schooling, and has a good job, the pool of eligible bachelors is much smaller. Guys are much more willing to marry down.
