The Chemical Basis of Morphogenesis

"The Chemical Basis of Morphogenesis" is an article written by the English mathematician Alan Turing in 1952 describing the way in which non-uniformity (natural patterns such as stripes, spots and spirals) may arise naturally out of a homogeneous, uniform state.[1] The theory (which can be called a reaction–diffusion theory of morphogenesis) has served as a basic model in theoretical biology.[2]

Reaction–diffusion systems

Reaction–diffusion systems have attracted much interest as a prototype model for pattern formation. Patterns such as fronts, spirals, targets, hexagons, stripes and dissipative solitons are found in various types of reaction-diffusion systems in spite of large discrepancies e.g. in the local reaction terms.

Reaction-diffusion processes form one class of explanation for the embryonic development of animal coats and skin pigmentation.[3][4] Another reason for the interest in reaction-diffusion systems is that although they represent nonlinear partial differential equations, there are often possibilities for an analytical treatment.[5][6][7]
