At the beginning of a game, I'll pick one or two ladies for the Village "Mama"s. And then add two to three more by mid game. (Usually spaced apart so the kids aren't all the same ages.) At the end I'll pick a guy in each generation to be a breeder and then they'll make sure the population stays steady. I've noticed that the ladies will usually go for the same "Alpha Male" on the list, and the guys will often find the oldest ladies first.

I had one game where I selected nearly everyone for "parenting", they ended up just pacing near the "Love Shack" in packs.
