In 1952, Alan Turing published an article called The Chemical Basis of Morphogenesis in which he offered an idea as to how reaction-diffusion equations could help explain various biological structures: the spacing of rows of alligator teeth, the spots on cheetahs, the position of leaves on some plants… Beside the article itself that is quite fascinating, it’s interesting to see that today, nearly 70 years later, there is still no scientific consensus on whether to accept or deny his theory.
