Even within apes the variance is wide enough that I question the value in drawing any conclusions about human nature, especially for laypeople. Why chimpanzees and not bonobos who are equally close relatives to humans but whose social structure is matriarchal, non-territorial, and considerably less violent? There is such myriad behavior in the animal kingdom that drawing insight into human social structure from it seems like it is more often a Rorschach test than it is a scientific exercise.
