AP Environmental Science Question of the Day

Practice AP Environmental Science with the production-style question-of-the-day selection for this public URL.

Question 1

The streamlined shape found in the body plans of both sharks and dolphins is an example of:

  1. convergent evolution
  2. coevolution
  3. divergent evolution
  4. sympatry
  5. none of these
Explanation: Sharks and dolphins are not closely related and evolved their streamlined shapes separately from one another. This is an example of convergent evolution, in which two species that are not closely related evolve similar characteristics. Divergent evolution is the opposite.
