WebAdaptation does NOT include an organism learning new behaviors unless these new behaviors are the result of a heritable feature. Phenotypic features, or traits, that result in a species' evolution are the adaptations we are concerned with in biology.

WebIn the context of evolution, phenotypic plasticity demonstrates the two meanings of adaptation: the plastic response is itself an example of a physiological adaptation and it is widely held that the ability to be plastic is adaptive in the sense of increasing fitness.
