Quizplus · Accepted Answer

Adaptive radiation is the process by which organisms diversify rapidly 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. This is often observed in closely related species that have evolved different adaptations.
