A Correct answer
Explanation

Adaptive radiation is a process in which organisms diversify rapidly from an ancestral founder species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges or opens new environmental niches. There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them have evolved from one ancestral form.
