For Adaptive Radiation we have terms and definitions in 5 topics. The topics are Anthromorphemics, Anthropology, Biodiversity, Evolution and Physical Geography.

Adaptive Radiation (Anthromorphemics)

The evolution of a single evolutionary stock into a number of different species.

Adaptive Radiation (Anthropology)

The evolution of a single evolutionary stock into a number of different species.

Adaptive Radiation (Biodiversity)

The evolution of a single ancestor species into several new species within a relatively short period of time and in a certain geographic area. The plants and animals of the Galápagos Islands are a result of adaptive radiation, where one plant or one animal species diversified into many species that fill a variety of ecological roles. For example, more than a dozen species of finches evolved from a single founding species that colonized the islands from the mainland of South America.

Adaptive Radiation (Evolution)

The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches (for example, Darwin's finches). The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals."

Adaptive Radiation (Physical Geography)

The evolution of a number of new species from one or a few ancestor species over many thousands or millions of years. Normally occurs after a mass extinction creates a number of vacant ecological niches or when a radical change in the environment produces new ecological niches.
