Which of the following best characterizes an adaptive radiation? a. Speciation occurs extremely rapidly, and descendant populations occupy a large geographic area. b. A single lineage diversifies rapidly, and descendant populations occupy many habitats and ecological roles. c. Natural selection is particularly intense, because disruptive selection occurs. d. Species recover after a mass extinction.
