Natural Selection and Adaptations

When the peppered moths' light-colored trees were covered in soot, the forest was suddenly made up of dark-colored trees.  Which of the following explains what will happen to the moth population?

• The light moths that survive will not mate and have offspring because they know that their offspring would easily be seen and eaten by predators.
• The light moths that survive will have dark offspring because the change in the environment will cause the parents to have offspring that would do better in the new environment.
• The light moths will see that the dark moths will be less likely to be eaten by predators, so they made themselves dark as well.
• The dark moths will be better camouflaged from predators, so more of them will survive and pass on those traits.
