I have to ask you to define your terms. Even a small hunter/gatherer group can be said to have a 'culture' which it attempts to pass down to its young. Is that what you mean or do you mean something a bit more structured?
minim -
quite a bit more structured. sorry - didn't go nearly far enough.
what i'm talking about is the transition from literal thought to abstract thought.
i present abstract thought as a mutation that greatly improved the ability of the human species to survive. too much, perhaps, given the sorry state of the earth today.
abstract thought, to my mind, resulted directly in representational art, and language, and later written language. the reason? a method of transmitting multi-generational knowledge without the necessity of the original knower being physically alive.
so if your water hole has dried up and all the game has moved away and you're looking at that old map great-grandad pecked into the rocks, or the oral tradition of your clan, or the rand mcnally atlas, or usgs topo maps then you can project yourself into the future, to the waterhole 200 miles away. and survive.
an unintended result of abstract thinking is pure art, aesthetics, which doesn't seem to have anything to do with survival, but a sensation of pleasure.
why humans do this, and animals apparently don't, i can't answer.
what i'm really interested in is the exact moment, the threshold when literal thought turns into abstract thought. and when and how that might have happened in the history of early man.
we think its so simple. i gave a friend directions today, how to go a couple hundred miles to arrive at a specific bend of a specific river, to fish for trout. and i drew a map on a piece of paper. and he did just that. now imagine your life without that ability.
and project that into prehistory.
i've got more question than answers.
