When might you be polygynous?

Does high pathogen stress change the way we couple?

It looks like polygyny often comes with that stress, in smaller societies. And when men provide for less food for women, and women can get more food for themselves.

So, monogamy shows up when men are needed for food.

And when the quality of males is more even!

In high pathogen stress environments, the average man is less capable.

Then, women, on average, flock more to the top.

This is not our context, but it does give us something to consider.
