Detailed explanation-1: -adaptive radiation, evolution of an animal or plant group into a wide variety of types adapted to specialized modes of life. Adaptive radiations are best exemplified in closely related groups that have evolved in a relatively short time.

Detailed explanation-2: -Adaptive radiation is the evolutionary divergence of members of a single ancestral line into a series of different niches or adaptive zones.

Detailed explanation-3: -In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago.

Detailed explanation-4: -1 Adaptive radiation. Adaptive radiation is a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity. The driving force behind it is the adaptation of organisms to new ecological contexts.

Detailed explanation-5: -Adaptive radiation, as a phenomenon, has tremendous research potential: The existence of a suite of closely related species adapted to exploit different habitats or lifestyles allows one to make comparative studies on the processes of speciation and selection in natural populations.
