There are a lot of holes in that theory, including neglecting to include that the advent of socially stratified societies ironically caused them to spread because they were so disruptive. Conversely, suppressing our primate ancestors’ dominance hierarchies by enforcing these egalitarian norms was a central adaptation of human evolution. We have plenty of ways of knowing this stuff beyond comparisons to contemporary H/G bands. (And if we didn't, as you claim, then how can you also assert that some groups were egalitarian but others weren't? How would you be able to know that?)
There is no archeological evidence of warfare before 13 thousand years ago. The time period I'm discussing is 30,000 years before that. You are trying to refute my thesis about apples with oranges.
