Text Solution

Verified by Experts

The correct Answer is:
A
The diversification of an ancestral group into two or more species in diffenent habitats is called divergent evolution. When this involves large number of speries to occupy different niches) this is called adaptive radiation.
Adaptive radiation is the process of evolution of different species in a given geographical area starting from a species of animals or plants and literally radiating to other areas of geography (habitats). Darwin's finches represent one of the best examples of this pbenornenon. Australian marsupials are rrnother example of adaptive radiation.
