2004-11-17 The disruptive selection definition is defined as an evolutionary force that drives a population apart. The disruptive selection causes the organisms with intermediate traits in order to reproduce less, and allow those organisms with extreme traits to produce more. Adaptive divergence, which usually explains rapid diversification within island species, might involve the positive selection of genes.

For example, Manier et al. detected diversifying selection of different ecotypes of garter snake Thamnophis elegans (in terms of coloration and scalation). Cox & Rabosky found that strong selection promotes color polymorphism across spatial and temporal scales in the highly polymorphic ground snake (Sonora semiannulata).

Diversifying Selection Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, on average, less fit. Known as diversifying selection (see the figure below), this is seen in many populations of animals that have multiple male forms.
