Question

10 multiple choice 1 point
adaptive radiation often follows:
climate stability
increased extinction
mass extinction events
genetic uniformity

Explanation:

Adaptive radiation is the diversification of a group of organisms into forms filling different ecological niches. Mass extinction events create empty niches. Organisms then adapt to these new niches, leading to adaptive radiation. Climate stability (A) doesn't create new opportunities. Increased extinction (B) alone isn't the key trigger. Genetic uniformity (D) reduces variation for adaptation. Mass extinction events (C) provide the necessary ecological release for adaptive radiation.

Answer:

C. Mass extinction events
