As I said as one example: "Once the dudes found it essential to keep track of who their kids were for purposes of property transfer (of farms and stuff) to future generations, it became necessary to essentially own women so you could control their procreation."
Maybe the initial spur was the male's role as warmakers aquiring a secondary "aquisition of resources" aspect. In a hunter-gatherer society war was for defence and maintaining the status quo, and as I've said, a case can be made that women were pretty damn valuable, maybe more than the expendable men
BUT farming and food surpluses changed this. Farms and produce were the first "above sustinence" resource, and as we know, the first powerful civilisations grew as a result of that power derived from agriculture. Suddenly, war's status rose... being able to take control of these sources of power would have given greater status and control to the dudes as war-makers. The roles stayed the same but their statuses changed. "Home makers and carers" no longer had high status. Things like patriarchal organised religions followed from this new culture of institutional male supremacy.
Once inheritance of land became the main source of power, a way to keep control of war-aquisitions it was necessary. But how could you be sure whose kids where whose given that WOMEN are the babymakers? You had to take exclusive control of the babymakers (or the "home makers and carers"), that's how. Hence, a culture was created in which exclusive bonds, even nonconsensual bonds, which subjugated and abused women, was the norm thanks to the increased status of war in societies where you could own property. Women were a victim of history.
The more I think about this, the more it seems that the initial roles were biologically determined, but the way they manifested socially and culturally was very very historical.
