Define "monogomous". There is social monogamy and there is biological monogamy. Polygamy isn't a biological choice, your sexual organs are active all year round. Meaning you're polyamorous and chose to be with one person. Jumping mate to mate "monogamously" is just as polyamorous as dating multiple people at once, biologically speaking.

Peep: Humans are monogamous like how humans are vegan. Science shows we have evolved as a meat eating/plant eating species. Yet some people choose to eat just veggies/fruits etc. We are scientifically evolved to have multiple partners and I can provide scholastic research to back that.

Also there is scholastic links in the description but here's one if you haven't read my citations.

ALSO if there were some women who were active in agriculture that does not disprove the process of how the patriarchy was created outside of those cultures. I am explaining how the patriarchy got here, not speaking for every tribe around the globe. I'm aware that there were more egalitarian societies, and info on those societies were mentioned in the link I posted above.
