Men have a stronger interest in preventing women from acting on those desires but since women almost all reproduce their desire to do so hasn't been selected out. Men win that contest when society doesn't break down.

There's an even simpler hypothesis.

You have a massive selective event for men ~10k years ago. There's no such selective pressure for women. There's no mtDNA selective bottleneck to radically change women's nature so they get minor tweaks to the old behavioral program which is still there and ready to activate.

I don't think there was any massive selective event 10k years ago.

This looks like a massive selective filter to me - what am I missing?pic.twitter.com/IpiFSPJFDl

The Y chromosome is small; it's not likely that men with particularly effective Ychrs took over. Some subpopulations of men took over, and their Ychrs dominate as a result. The genomes of the other men are still around, except in their paternal lines.

It doesn't even have to be particularly violent to work: found a dynasty, one where your sons, and your sons' sons, have 4 kids while everyone else has <2, and 500 years later your Y chromosome is dominant. It's happened in living memory multiple times.

Doesn't necessarily require any selective pressure on the Y chromosome its own self.

Not necessarily but it absolutely is selective pressure on male phenotypes as demonstrated by the bottleneck on Y chromosomes

No. If the other men's genomes are still around --- and they are, everywhere --- then there's no selective pressure on male phenotypes specifically, unless it's specific to the Y chr.

Explain that to peacocks where there's strong selective pressure on the males not on the females and yet elaborate tails exist. Male cooperation in war bands is a peacock's tail in the sense that it's not found in women b/c it's not under pressure to exist in women.
