In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges and opens environmental niches. Starting with a recent single ancestor, this process results in the speciation and phenotypi...

The evolution of various divergent life-forms from a primitive and unspecialized ancestor. As the original population spreads out from its center of origin to exploit new habitats and food sources, new populations emerge, each adapted to its particular environment. Eventually, these become sufficien...

Adaptive radiation is the diversification of a species as it adapts to different ecological niches. If successful, the species become specialized for the new environments (the mechanism being natural selection), and they eventually evolve into different species.

In evolution, the formation of several species, with adaptations to different ways of life, from a single ancestral type. Adaptive radiation is likely to occur whenever members of a species migrate to a new habitat with unoccupied ecological niches. It is thought that the lack of competition in such niches allows sections of the migrant population ...
