IT'S ALL WHO YOU KNOW: THE EVOLUTION OF SOCIALLY CUED ANTICIPATORY PLASTICITY AS A MATING STRATEGY

Selection has led to the evolution of a variety of different mating strategies, each adapted to different competitive challenges. But what happens if the competitive challenges depend on the social environment? Here we discuss and review examples of socially cued anticipatory plasticity: irreversible developmental tactics in which resource allocation during the juvenile stage is altered to develop an appropriate phenotype for the competitive or mate choice environment that an individual encounters when mature. There are numerous theoretical and empirical examinations of the role of the social environment on the strength and direction of selection. However only a handful of empirical studies examine how the social environment affects juvenile allocation and whether such tactics are adaptive. The goal of this review is to synthesize current knowledge about socially cued anticipatory plasticity, including the sensory modalities that individuals use to predict the adult competitive and mating environment. We then outline the various factors that are necessary for the evolution of socially cued anticipatory plasticity and discuss how this can affect phenotypic evolution.. We conclude by suggesting some directions that future studies should take in order to understand how social variation can alter selection and the evolution of development.
