it's not as beneficial to the species to simply have a lot of kids with the same women. That's not how the maximal amount of genes get to interact. The most benefit comes when a man has children with many different women.
If you want to think of it like this: man A has 10 kids by 10 different women and man B has 10 kids (10-tuplets) with 1 woman. The population goes up by the same amount but biologically man A has helped his species many times more than man B.
The point is not a maximal number of kids, it's a maximal number of impregnated women.
bel,
I don't think there is anything wrong with having two parents. I just think that evolution has programmed the mother to take care of the child more so than the man. With the divorce and sposal abuse rates in this country, it would seem like there is a greater chance for their to be psychological damage done from having two parents vs. just the mother. |
