Expression of Fashion in Female Preferences for a Mate by Conformity and Differentiation Genes

It is generally thought that living things have desires for conformity as well as desires for differentiation, which makes their preferences show fashion. Recently, it was shown that there were fashion in preferences of how female birds chose their mates. We think fashion in female preferences for a mate is related to their desires and that the strengths of desires among living species are genetically different from one to another. We describe the strength of desires among living species as being artificial agents of genes. In this paper, we simulate the phenomenon of fashion in female preferences for a mate by using an agent model that consists of imported conformity and differentiation as genes. In this experiment, we found that there were two kinds of periodic phenomena of fashion and reported the influence of conformity and differentiation on the transition of female preferences.
