its mostly from stuff i studied in my college cutural anthropology classes.
group "leaders" in largely egalitarian societies were often leaders becuase they had a lot of male relatives they could call on. if i wasent at work i could try and dig out my old text books for more specific examples

edit since we were discusing how nobility arose i was only looking at groups with fairly simple organizastional structures. in in those situations more ussualy is better
