WebGould and Lewontin (1979, 592) classified phenotypic plasticity as a type of “adaptation without selection": the fact that phenotypic variation may not require genetic variation means that selective environments can increase the propensity of a phenotype in a population without requiring genetic mutation or reproduction. Selection can even ... Webwith irreversible phenotypic changes and apparent geno-typic shifts, especially at the challenging temperature of 32 C. This demonstrates its ability to adapt more rapidly, but also implies a potential lack of thermal plasticity com-pared to Trichodesmium. However, it is unknown whether adaptation was halted for Trichodesmium or might occur
