That's very promising since some of the most undesirable characteristics can be bred out within a few generations. Actually that might have been what happened to some isolated cultures (even if nomadic) where they had nothing to fight over for thousands of years.
While other isolated or marching cultures bred out any non-violent tendencies in the opposite way themselves.
See my reply to my comment - I kind of feel a bit more optimistic, as I finally watched the Veritasium video I've tucked away in my Watch Later the past few weeks.
