Question

Which of the following defines the relation between adaptive radiation and natural selection?

• A. Natural selection is usually the principal mechanism driving adaptive radiation.
• B. Natural selection leads to adaptation during adaptive radiation.
• C. Natural selection causes mutational changes during adaptive radiation.
• D. All of the above.

Answer 1

The correct option is A Natural selection is usually the principal mechanism driving adaptive radiation.

Natural selection and adaptive radiation are related to each other. A progressive change in which organisms diversify rapidly from an ancestral species into two or more groups to adapt to the changing environment is called an adaptive radiation. Natural selection is the adaptation of the individual towards the changing environment to survive. So, natural selection is the principal mechanism driving adaptive radiation. So, the correct option is A.
