Quizplus · Accepted Answer

Adaptive radiation does not occur simply due to the evolution of large brains in a species. It requires ecological opportunities, such as the absence of competing species or the opening up of new environments through extinction events, for a group of organisms to diversify and evolve into different niches. The displacement of specialized species by generalized ones can also provide ecological opportunities for adaptive radiation to occur.
