Please don't tell my wife that and i'll keep her away from the biology books!

Actually, that's not how it works - not for males.

Males aren't 'programmed' to pick out the best mate - they are programmed to get the most mates possible. There's no shortage of sperm, so there's no pressure to discriminate.

The female mammal, however, having but one uterus, is under considerably more pressure to discriminate.

Which is why packs of mammals tend to have groups of females, all 'serviced' by one dominant male. The male tries to copulate with all of them, not just the 'best'.
