Nah, it's a good point.

We simply know that, in the case of lions (and apparently feral domesticated cats too), a male lion taking over a pride will kill all of the cubs (if he can) so the lionnesses will need to mate again - but with HIM. Talk about ego! "Get alla these babies outta here! You want babies, I'll give you babies!!!"
Works for lions/cats. Not for us crazy two-legged human beans. We're very civilized, noble, proper.
Holy living HELL, Skep-Greg beat me to the punch!!! Where's my javelin???
