Answer on @Quora by @AdrianaHeguy to If other male mammals mate with such young female mammals, – Xochielt Sanchez
Answer by Adriana Heguy:
The naturalistic fallacy and the appeal to nature fallacy rear their ugly heads.
Let's not confuse "natural" with "good", as a first step. To illustrate the point, some male mammals kill other male mammals in order to mate with females, why is this such a problem for humans? Come on guys, we are all mammals, what's a few deaths of men here and there, in the overall pursuit of young females?
In any case, not all male mammals mate with young females or even like young adolescent females. Many social mammals have distinct rules about who gets to reproduce and when. Alpha females in wolf packs are not the younger females in the pack, for example. Male chimpanzees have a preference for experienced mothers, they prefer to mate with females who have had babies already as this gives them the highest chances to pass on their genes. Apparently the adolescent female chimps do not see much action ().
The OP is confusing is with ought (http://www.eurekalert.org/pub_releases/2006-11/cp-mcp111606.php) and also assuming all male mammals behave in the same fashion when it comes to mate preferences, which is an oversimplification.
