Tony: And my point is that our assumptions about them does not mean that they were NOT complex. Assumptions about the sophistication of a certain peoples, modern or ancient, are just that, assumptions.-Fair enough, but: small fractionated groups of hunter-gatherers with up to 35 folks in the tribe, without the dream time overlay in Australia, are mainly survivalists in forest or jungle or desert, with certain assigned roles. These groups have been studied and I don't see much complexity being present in what is described.
