Detailed explanation-1: -In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.

Detailed explanation-2: -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-3: -Adaptive radiation is the phenomenon by which an ancestral group of organisms diversifies into various related forms, adapting to different environments.

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: -Speciation occurs as a result of adaptive radiation. When a group of individuals within a species gets departed from the rest of the species and the development of its own distinct features takes place, this is known as speciation.
