Yippee : “But I have yet to hear anything from JP, or those who follow his work on this thread, about the structures developed possibly as a consequence of biological sex roles but whihc clearly and deliberately oppressed women.
Why is that???”
I see that I missed this interesting question from earlier in the thread. I’ll do a bit of a Cathy – so you’re asking, what is there about those parts of human culture and structures that deliberately oppress women, that seems to be derived from biological sex differences ?
I’ll offer the rather common cultural construct of society trying to control female reproductive freedom. (I don’t mean abortion, I mean mate choice, chastity, adultery etc.)
Taking humans as a species which relies on pair bonding as a stipulation, let’s look at the nature of the bargain. The female gets some sperm and some resources (food, protection etc for her and her children.) The male gets exclusive sexual access, ie some eggs and some services (household, childcare.) The partnership, if executed according to its terms, delivers both parties evolutionary benefits – a chance to pass on their genes to the next generation.
So what’s wrong with the deal ? Well, each party can cheat. But the cheating is asymmetrical. If Dad cheats (sexually) – what’s the cost for Mum ? Usually nothing. Dad isn’t going to run out of sperm. What matters to Mum is whether there’s any risk to the promised supply of resources. The sort of dad cheating that matters to Mum isn’t him playing away sexually, it’s him not providing resources. But whether or not the resources are delivered as promised is an open book. Mum knows whether Dad is keeping to the bargain. So does the community. A transgression is obvious. If Mum cheats – what’s the cost for Dad ? Everything. His entire life is a failure. He spends his life working and providing resources to get someone else’s genes into the next generation. Moreover Mum’s cheating is secret. It’s much harder to detect than Dad reneging on his promise to provide resources. And even if the cheating is detected, you still don’t know whether the baby is Dad’s or the other guy’s.
And people have done psychological experiments on jealousy (see the book at the end.) On average if Dad has a meaningless sexual fling, Mum gets a bit jealous. But what makes her insanely jealous is if he forms a close friendship with another woman. (Presumably because that represents a risk that he’ll break the existing pair bond and form a new one with the other woman.) Whereas if Mum has a meaningless sexual fling with another man, Dad gets insanely jealous. Whereas if she forms a close friendship with another man, Dad doesn’t mind at all, unless he fears that it might turn sexual.)
Mate guarding is ubiquitous both in pair bonding species and in species where one male gathers a harem and defends it against other males. For obvious reasons. So why would it be surprising that when one species develops a big enough brain to start developing a culture, and when the social group is dominated by men (see earlier comment on violence) - the cornerstone of the culture would be rules to police female chastity and to punish adultery. It’s mate guarding translated directly into culture.

The Adapted Mind: Evolutionary Psychology and the Generation of Culture
is pretty much the foundational work of modern evolutionary psychology. It’s a bit out of date now, but still fascinating. Somebody earlier in the thread said that evolutionary psychology is “just so” stories. It isn’t, and some of the chapters describe very clever experiments in psychology. But there’s a bit of truth in the argument that these people sometimes take their inferences too far into the realm of speculation, so later workers in the field have reined in some of the claims. But it’s still a real eye opener. The experiment on sex differences in spatial awareness and pattern recognition is simply brilliant.
