Turing patterns

Turing patterns are natural designs, like spots or stripes, that emerge on animals' skin or in chemical reactions. They form when simple processes of local activation and inhibition create organized patterns from initially uniform conditions. Alan Turing proposed that these patterns result from reacting chemicals that spread and interact, leading to stable, repeating structures. This mechanism explains how diverse patterns like those on zebras or butterflies develop during growth, illustrating how complex order can arise spontaneously from basic rules in biological and chemical systems.
