Definition
Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)
- 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 "Cladistics (2nd ed.)" by Kitching et al. (1998)
- 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.
