What Darwin Never Knew

Which of the following statements best describes what will most likely occur to the moth populations in the image above?

• The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.

• The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.

• The light moths will change their wing color to match that of the dark moths.
