Na'vi sociology

[Raptor]

This is an interesting topic. As far as we know, does the Na'vi even have a social hierarchy? Also, are positions within the clan given based on achievement or family history? How much to they weight competition vs cooperation?

JC is supposed to address this in the novel, which I haven't heard any updates about.

Nope. Evolution dictates that the ones who possess higher fitness (i.e. more likely to pass on their genes) survive. That doesn't automatically mean that individuals have to be callous and greedy. It does fuel competition, but saying that evolution made everyone and everything inherently greedy is a gross oversimplification. I like being competitive, but there's a line (albeit a thin one at times) between being competitive and being greedy.
