Design In Nature -3-

“To underscore this observation, let’s return to the circulatory system. It is one of the marvels of nature that this system is so exquisitely complex that no cell is far from a life-sustaining capillary. It transports blood from the heart to this vast volume by reconfiguring its design through branching. The same with the lung: The trachea begets two bronchi, each of which branches off into smaller tubes, which branch off into two smaller tubes, etc. Thus we see the same design we witnessed in rivers—the creation of streams and channels to improve access for flow—but with much greater precision. Instead of a range of between 3 and 5, we find the number 2 every time (until the very smallest scales). We see then that the inanimate system of the river basin and the animate system of blood vessels and air passages evolve toward the same design structure. We should add that the structure of the circulatory system might indeed be imprinted in our DNA so that the entire structure emerges in toto. But the DNA chemistry alone cannot account for the fact that the same phenomenon governs the evolution of river basins, lightning, and city traffic. The answer is the constructal law.”

Question: If the constructal law governs the DNA of anatomy, physiology, neurology, should we expect to find it in the DNA of behavior?
