adaptive radiation
adaptive radiation 1. A burst of evolution, with rapid divergence from a single ancestral form, that results from the exploitation of an array of
habitats. The term is applied at many taxonomic levels (e.g. the radiation of the mammals at the base of the
Cenozoic is of ordinal status, whereas the radiation of
Darwin's finches in the
Galápagos Islands resulted in a proliferation of species).
2. Term used synonymously with
cladogenesis by some authors.
