There I was, out in the wilderness for months, lost without all my old friends. And then I find them all in here, discussing juju.
I've always thought of the 'traditional' male role as disposable. A community can lose 80% of its males in hunting or fighting with other communities and still survive - one male can impregnate many women, if the need arises.
On the other hand, more women are required to maintain a population level. So the men were detailed for the dangerous jobs. Women had different roles, and as noted above, many were the decision makers.
A fairly rational approach, in a hunter gatherer society. Being humans, we'd apply all sorts of mythological and social conventions to the roles that would provide people with their empowerment and sense of belonging in the community.
However, we've moved into other cultural and economic relationships, and held onto the traditional roles. The result is that few men hunt or fight other tribes, and all the rest of us have left (of that history) is sports, war and the enduring patriarchy. Neither war nor patriarchy is much use to the new economic system, but our bad habits have managed to perpetuate them both, to the detriment of all of us.
A division of labour that makes sense when life expectancy is about 30 years, and survival of the species is paramount is entirely nonsensical when most men and women survive into old age, and the species isn't going anywhere. Yet, being humans, old habits die hard, and we've managed to hang onto, and expand upon, some of those old divisions into entirely new and twisted iterations (i.e. subjugation of women, non-personhood etc).
Luckily for all of us, women have decided not to stand for it, and hopefully things will continue to evolve in healthy directions.
On the other hand, I'm likely full of shit, as it has been at least 10 years since I did any serious reading on the roots of patriarchy.
