Many scholars vehemently reject this theory, insisting that both monogamy and the forming of nuclear families are core human behaviours.
I don’t understand what “core human behaviors” means. Clearly, humans became socially monogamous at some point in our genetic history or in our evolutionary tree. The question is when. This seems to get into the false “humans are/are not naturally monogamous debate”. Even if our distant ancestors were not monogamous (which he doesn’t provide any evidence for) that doesn’t prove that monogamy goes against our “default settings”. We didn’t stop evolving when we were hunter-gatherers.
