Question

Darwin's finches are good examples of

• A. convergent evolution
• B. mass extinction
• C. industrial melanism
• D. adaptive radiation

Answer 1

The correct option is D adaptive radiation

Adaptive radiation are phenomena where in many new species arise from a single common ancestor and then radiating out or getting established in different geographic areas. Darwin's finches are examples of adaptive radiation. They first arose in Galapagos Islands about 2 million years ago. From this ancestor many different species evolved which were adapted for different types of habitats and food sources. They moved out and established their populations in geographical areas other than the Galapagos Island.
