Adaptive radiations can be a direct consequence of three of the following four factors. Select the exception.
A) vacant ecological niches
B) genetic drift
C) colonization of an isolated region that contains suitable habitat and few competitor species
D) evolutionary innovation

Question

Quizplus · Accepted Answer

Genetic drift is a random process that occurs in small populations and can lead to changes in allele frequencies, but it is not a direct cause of adaptive radiations. The other three factors (vacant ecological niches, colonization of isolated regions, and evolutionary innovation) can directly lead to adaptive radiations.
