>>8359>Basically it all stems from now-gone tribal material conditions which have zero bearing on material conditions nowNah up until very recently childbirth was hugely risky and often took a massive toll. Something like 1/3 of women died in childbirth across history. It's something that was very much with us until modern medical advances changed things (including birth control and abortion as a medical procedure), which is the reason you saw feminism etc take off when it did and not a lot earlier in capitalism. We do still have some of the material basis for this, it's just been lessened greatly.
More to the point, power no longer passes through noble family lines, but through ownership of property. This means that inheritance really isn't such an important question as capital will pass to somebody who can manage it regardless of whether Porky can give it to Porky Jr. This is a big upgrade because succession is not a major source of crisis any more.
Even with a patriarchal system this had a lot of problems, but if society was run by women usually or even sometimes there would be a significant risk of death during an attempt to produce an heir. This means that societies that only allow men to rule are less likely to have that kind of succession crisis. On the other hand, they are likely to have a different one: the king is a cuckold. A quirk of reproduction is that the paternity of a baby is not clear (again until modern medicine worked this out). If there turns out to be a problem with the royal line, that is going to cause political instability and threaten the system with crisis. For this reason it becomes necessary to strictly control the female side of reproduction. There really wasn't any other way to ensure proper inheritance, and of course that's going to matter for biological reasons. Obviously somebody who passes power to their descendants will be more successful in evolutionary terms than someone who doesn't, so in the long run the rulers who protect their legacy are going to be more successful at reproducing and the trait will come to dominate. Those are the three key ingredients pretty much:
>high lethality of reproduction for women>reproductive infidelity for men>drive to pass power to your offspringThere are other ways around this and of course the systems got a lot more complex with rules for the line of succession, but this is the material basis they had to work with.
>>8363Origin of Family Private Property and the State is very outdated. He was limited by the science of his time. It should not be taken as reflective of the knowledge we have now.
>>8366>1. strength and warThis is relevant to the detail of warrior classes and the like but that operates on different factors from who is "fit to rule" so to speak. It's incidental that women are smaller and weaker than men. The opposite is true in some animals. Physical dominance and power is more about who you can get to support you than fighting for dominance yourself, which is very specific to humans. If women were larger than men but the mechanics of reproduction still worked as described above, men would still dominate politically.
It wouldn't really make sense to have women warriors even in this case, though, because of the reproductive bottleneck. Losing women to war reduces the rate the population can replenish itself, which is probably a major factor in human sexual dimorphism being what it is. Men by nature of how they reproduce are more expendable than women (1 man can impregnate an arbitrarily large number of women), which means they are more suited to being warriors from a Darwinian perspective. With that being the case, it makes much more sense for men to tend to be larger and stronger. And indeed you tend to see larger females in species that are less social, like lizards or fish. In those species the size difference is more a function of male bodies not needing to be as big to make sperm as female bodies need to be to make eggs. Organized war-like practices are irrelevant to those species.
>2. women anchored to offspringThis is a significant factor for working classes, but not so much for rulers. Nobles's "work" could be done in tandem with taking care of children a lot more easily than manual labor can, and of course upper class women employed lower class women to tend to their children, so this is really not a big factor for who wields political power at the top. It is very relevant to the commoners, though, and shapes a lot of how society looks for most people's daily lives.
>3. women take fewer risksThis is probably more effect than cause, irrespective of whether it's nurture or nature. If women didn't face higher physical costs for pregnancy they might be more open to sexual risks for example. Behavioral tendencies are pretty much a second order effect and follow from more foundational biology, like the costs and risks associated with reproduction. It probably also ties in a lot to the disposability thing mentioned above.
