Question

An evolutionary pattern characterized by a rapid increase in the number and kinds of closely related species is called

• A. Convergent evolution
• B. Divergent evolution
• C. Adaptive radiation
• D. Parallel evolution

Answer 1

The correct option is C Adaptive radiation

Adaptive radiation refers to the diversification of a group of organisms into different forms and occupying different ecological niches.

An example of adaptive radiation can be seen in the variety of beak types seen in the finches of the Galapagos Islands. These finches have specialised beak shapes depending on their primary source of nutrition (e.g. seeds, insects, nuts, nectar)
