I wasn't suggesting that evolution thinks, I was suggesting that we've evolved to produce more males so that there's an optimum 50/50 balance of the number of males and females at around early adulthood. Considering some of the other things that evolution has achieved that seems like a pretty reasonable thing to suggest. Your explanation of whether certain couples can only produce males or females was pretty interesting though, thanks.
