Question

Quizplus · Accepted Answer

The statement about adaptive radiation that is false is that adaptive radiation is not driven by natural selection. The process occurs as the result of natural selection.
Key Takeaway: Adaptive radiation is a rapid evolutionary process characterized by an increase in the morphological and ecological diversity of a single, rapidly dividing lineage. It often occurs in organisms without a defined niche, as the species may radiate rapidly to take advantage of all of the unoccupied niches. In Lake Victoria, a lake in the African rift valley, over 300 new species radiated from a single lineage over the course of 15,000 years.
