Falling back again to the research done by Levin lab, they are able to shape 2-headed or 2-tailed flatworms by altering electric potential differences, and these flatworms have the same DNA as the regular one head, one tail flatworm [1]. See them in video [2]. One other lesson to be learned from the planarian flatworms is that their DNA is a complete mess, yet they are able to fully regenerate without any issues, and are functionally immortal, they do not age [3]. DNA is certainly important and interesting and needs more research, my initial comment just pointed out that if DNA is a "CAD model", the computational layer, the basal cognition in cell/tissue/organ(ism), is even more enticing, and probably we don't even need to alter genes in order to shape morphology, giving another analogy, if a pocket calculator "knows" what 5 + 7 is, we probably don't need to build another pocket calculator just to compute 6 + 8.
