Influence of plasticity and learning on evolution under directional selection.
Phenotypic plasticity and related processes (learning, developmental noise) have been proposed to both accelerate and slow down genetically based evolutionary change. While both views have been supported by various mathematical models and simulations, no general predictions have been offered as to when these alternative outcomes should occur. Here we propose a general framework to study the eff...
متن کاملPhenotypic plasticity, sexual selection and the evolution of colour patterns.
When a population comes to occupy a new environment, phenotypically plastic responses alter the distribution of phenotypes, and hence affect both the direction and the intensity of selection. Rates of evolution can be accelerated or retarded compared to what would happen in the absence of plasticity. Plastic responses in one trait result in novel selection pressures on other traits, and this ca...
متن کاملPhenotypic plasticity and selection in Drosophila life-history evolution. I. Nutrition and the cost of reproduction
Earlier experiments have shown that the evolution of postponed senescent populations can be achieved by selection on either demographic or stress resistance characters. Both types of selection have produced results in which survival characters (stress resistance and longevity) have apparently traded-off against early-life fecundity. Here we present the results of a series of experiments in whic...
متن کاملThree Facets of Organizational Adaptation: Selection, Variety, and Plasticity
When considering the adaptive dynamics of organizations, it is important to account for the full ecology of organizational adaptation, including not only the possibility of learning and adaptation of a given behavior, but the internal selection over some population of routines and behaviors as well. In developing such a conceptual framework, it is necessary to distinguish between the underlying...
متن کاملPhenotypic Plasticity and Selection: Nonexclusive Mechanisms of Adaptation
Selection and plasticity are two mechanisms that allow the adaptation of a population to a changing environment. Interaction between these nonexclusive mechanisms must be considered if we are to understand population survival. This review discusses the ways in which plasticity and selection can interact, based on a review of the literature on selection and phenotypic plasticity in the evolution...
