Detailed explanation-1: -Adaptive radiation is the evolutionary process by which many species originate from one species in an area and radiate to different species. The phenomenon of adaptive radiation was first observed by Darwin when he travelled to a place called Galapagos Island.

Detailed explanation-2: -An adaptive radiation generally means an event in which a lineage rapidly diversifies, with the newly formed lineages evolving different adaptations.

Detailed explanation-3: -An adaptive radiation is a burst of evolution, creating several new species out of a single parent species. As when we discussed species richness, it is useful here to think of uninhabited “islands” of habitat, though in this case, the islands merely need to be uninhabited by the species in question.

Detailed explanation-4: -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.
