Which 3 are true of adaptive radiation? Group of answer choices It increases the mutation rate. It occurs as a result of decreased selection pressures due to more resources with fewer competitors. It results in the formation of groups of related species. It often occurs on islands. It is mainly important in the evolution of fish.

Step 1
Adaptive radiation is a process in evolution where organisms diversify rapidly into a multitude of new forms, especially when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches. Step 2: Evaluate Show more…
