Which is why the false paternity rate < 2% everywhere in the Western world, going back at minimum hundreds of years.

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.

Wow that’s pretty fascinating. A quick search led me to this for anyone else interested in that graph: https://dienekes.blogspot.com/2015/03/bottleneck-in-human-y-chromosomes-in.html … Considering how many groups were impacted I can’t see how it was cultural? Virus maybe?

It wasn't a virus - it was expansion and warfare. Conquer the neighboring tribe, take their women as concubines. Intense selective pressure on men to cooperate in war bands; selective pressure on women to accept it (which they mostly did, obviously).

How does that happen across every human population group at once at a time when many of these groups had no contact with each other?

Birth of agriculture made more advanced hierarchies & greater scale of bride-gathering possible. It wasn't possible for a hunter-gatherer to feed and guard ten wives, it was for an early farmer. Think Jacob laboring for Rachel's father for 14 years to get two wives

Speculation but I think that's slightly sideways of it. Pastoralism is newer than hunter-gathering and with agriculture picking up pastoralists have a great target - societies with a concentration of wealth and women that can't flee or fight effectively.
