Actually, I wrote, not Don. My wording was certainly quite vague. If a mobile radial organism mutated so as to be a bit elongate, it would be more streamlined for travel in two directions, though less suited for going sideways. If one end is usually encountering things first, a concentration of sense organs at that end would be be selected for once mutations generated this configuration. Certainly God created all of them, but I do not believe that He would go to such great lengths to make it appear as though the organisms had common ancestry and had changed over time if He had not created them via evolutionary processes.
Evolution is a very effective method of design.
For certain processes, one of the best ways for humans to solve the problem is to use an evolutionary approach. God, being omniscient, does not have to experiment to find the best answer in such a way, but perhaps He decided that evolutionary means were the best way. There seems to be little serious consideration of the possibility that God can design through evolution among intelligent design advocates.
