  • The rapid evolution of a single species into many new species with different forms and habitats. Well-documented examples occur on island chains.

Glossary of "Evolution (3rd ed.)" by Futuyma (2013)

  • Evolutionary divergence of members of a single phylogenetic lineage into a variety of different adaptive forms; usually tha taxa differ in the use of resources or habitats, and have diverged over a relatively short interval of geological time. The term evolutionary radiation describes a pattern of rapid diversification without assuming that the differences are adaptive.
