Actually you're wrong. Within one tribe they were all peaceful and both the men and women were by our standards effeminate. In one the gender roles were reversed. In another both genders were highly aggressive. The text even mentioned that when they had sex they would come out all battered and bruised like Klingons.Well, "gender roles" is a pretty broad concept. I can see some gender roles as being society-dependent, but stuff like male aggression, female nurturing, etc. is most likely genetic methinks.
Any specifics on what was shown to vary between tribes/societies?
