Its Neolithic people behaving Neolithically!
If you go back 10,000 years or so in Europe, you find similar behavior, I have a book called “Warfare in Neolithic Europe: An Archaeological and Anthropological Analysis” that provides all the evidence. It mentions how initially the archeologists who were academically raised on the “noble peaceful savage” myth were shocked at all the evidence of warfare, savagery, cannibalism, etc. The had to adjust their attitudes to the evidence.
One thing all cultures do indeed share is how to be crappy to each other!
But if you point this out some people on this site will react in horror.
Not my ancestors they cry.
Yep. Yours. And not that much before those people.
And one thing Bronze Age cultures share is human sacrifice.
How un-woke of them. Haven't they ever heard of 'settled science"
