re: #84 b_sharp

Look at them as evolving. Evolution can only build on what already is and reacts to the environment, including itself.

Almost makes me thinks of Bonobos vs. Chimps (the former being described as “the hippies of the animal kingdom”, while the latter are face-ripping nasties). Could it be the violent tribes got to be that way because early on, they were led and dominated by violent people, while the peaceful tribes lucked out with better founders?
