Social structure modulates the evolutionary consequences of social plasticity: A social network perspective on interacting phenotypes.

摘要: Organisms express phenotypic plasticity during social interactions. Interacting phenotype theory has explored the consequences of for evolution, but it is unclear how this applies to complex structures. We adapt interacting models general structures explore number connections between individuals and preference phenotypically similar partners affect variation evolution. derive an analytical model that ignores feedback use simulations test predictions model. find adapting previous more does not alter their conclusions generates insights into effect structure on maintenance Contribution indirect genetic effects variance highest when interactions occur at intermediate densities decrease higher densities, approach with all group members, homogenizing environment across individuals. However, evolutionary response selection tends increase greater network as individual's genes are amplified through increasing other members. Preferential associations among (homophily) both within groups selection. Our results represent a first step in relating expression responses
