Think about what would happen if unattractive couples had more daughters. Their genes wouldn't be very successful. The same applies to the attractive couples who had sons: they wouldn't have bad results, but the results would not be as good as when they had daughters. It's all about relative success rates. Nature doesn't need to "know" anything,it just weeds out what doesn't work.
