English: Takashi Miura (2012): simulated finger bifurcation. Computer modeling of hand development based on Turing mechanisms has existed since 1974. [27] If the development of the vertebrate hand can be simulated in the model, the researchers in this group believe that such models must also be able to show how hand malformations are induced and how in the Special polydactyly influences the pattern formation of the hand. Takashi Miura, Kyoto, Japan, was one of the first to show in 2006 the conditions under which polydactyl fingers develop in computer models and what they look like. For example, he demonstrated bifurcations, which are new finger elements that are given off from existing ones, as well as thin new fingers or toes, as they typically occur in cats or mice (Doublefoot Mutant). ^[1]
