Recently I watched a documentary on the tanzanian Hadza tribe, one of the last hunter gatherer tribes on Earth. Their language is a distinct click and pop language and they regularly imitate animal calls (monkeys, baboons, birds) when they hunt but also when they communicate with each other, tell stories etc.

I think it's not impossible that words evolved as adaptations of the environmental sounds with which our ancestors lived. The human creativity producing DNA is also a remix of preexisting molecules formed under evolutionary pressure, so the view that it's turtles all the way down, unintuitive as it is, may not be so indefensible after all.
