If bio-systems are all about communication, how and why have human beings been cut out of the loop? In one version it has something to do with god, a tree, and a serpent. In another it was the loss of the rich biochemical soup we were fed in a mature forest that caused our mental capacities to diminish. In yet another we met a mind altering mushroom that stimulated our cultural development. In still another, aliens from deep space altered our DNA to make us a slave species. To indigenous people around the world, westerners have simply chosen not to listen to the spirits and have cut themselves out of the loop.
Each of these scenarios is dependent on a specific world view, but they have some common elements the indicate they might each have part of the story. It could be that each is a separate description of the same phenomenon? Could there be a simple biological explanation? I think there is. It requires no new knowledge, simply a new way of looking at human history.
