dhw: I have recognized the hierarchy of control. When I first suggested that cells may have an intelligent, autonomous, inventive mechanism which was the equivalent of the brain, I was aware of the fact that this mechanism would direct operations. Time to move on.-Fine-> dhw: Atheistic Darwinists will always cling to randomness and will be aghast at any suggestion of “intelligence”, just as some theistic Darwinists will always cling to their version of divine purpose and will be aghast at any suggestion that their God might not have been in complete control of evolution. But I don't think evolution is a matter solely of overcoming vast changes in Nature. The whole point of an inventive mechanism would be that it can exploit the opportunities offered by change, so broadly speaking I'd say evolution is a mixture of overcoming changes (adaptation) and making use of them to invent new forms of life (innovation).-Great summary.
