abstract
This paper reports our effort to abstract the evolutionary mechanism of color pattern generation and color pattern recognition, and to construct a model in which coevolutionary dynamics automatically generate some of the color patterns that one observed in nature one after another, by assuming that there is a symmetry in the evolutionary relationship between predators and prey. Each artificial organism in the model has a pattern development system and a pattern recognition system. As a predator, the production rules which develop the pattern for the recognition system evolve to recognize the prey correctly. As a prey, the production rules which develop the color pattern on its epidermis evolve to prevent the predators from detecting it or identifying its species. This mechanism can be a driving force of coevolution and promotes the generation of complex sequences of color patterns.
