“Its no more genetic than adultery. :-)”
Darwinists are now arguing that we “evolved” to have several sex partners. We are no better than animals after all, so why have limits?
Yes that is where the argument goes but that assumes that what is “natural” for animals or natural from a base level is natural or good for humanity. Most human beings have tended to attach themselves to single mates and there are many documented advantages for this. Hygiene as we see it today is unnatural too but only if you separate nature from what humans do which is silly.
