Phenotypic plasticity and experimental evolution.
Natural or artificial selection that favors higher values of a particular trait within a given population should engender an evolutionary response that increases the mean value of the trait. For this prediction to hold, the phenotypic variance of the trait must be caused in part by additive effects of alleles segregating in the population, and also the trait must not be too strongly genetically...
متن کاملAmphibious fishes: evolution and phenotypic plasticity.
Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favou...
متن کاملPhenotypic plasticity and evolution by genetic
Introduction Why revisit a 50 year old debate? Genetic assimilation is a process whereby environmentally induced phenotypic variation becomes constitutively produced (i.e. no longer requires the environmental signal for expression). Although the origins of this concept can be traced [genetic assimilation] is an interesting but, I would judge, relatively minor outcome of the [synthetic] theory' ...
متن کاملPhenotypic plasticity and evolution by genetic assimilation.
In addition to considerable debate in the recent evolutionary literature about the limits of the Modern Synthesis of the 1930s and 1940s, there has also been theoretical and empirical interest in a variety of new and not so new concepts such as phenotypic plasticity, genetic assimilation and phenotypic accommodation. Here we consider examples of the arguments and counter-arguments that have sha...
متن کاملRevisiting rapid phenotypic evolution in sticklebacks: integrative thinking of standing genetic variation and phenotypic plasticity
Phenotypic evolution can result from new mutation, standing genetic variation, or phenotypic plasticity. Extensive reviews have focused on either comparing phenotypic evolution by new mutations vs. standing genetic variation (Barrett and Schluter, 2008) or the effect of phenotypic plasticity on generating biodiversity (Moczek, 2010; Pfennig et al., 2010; Moczek et al., 2011). This article focus...
