The environment around Manchester, England, changed during the Industrial Revolution. How did this change affect peppered moths living in the area?

• Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.

• Natural selection favored moths with white wings that were easy for predators to see.

• Natural selection favored moths with white wings because predators could not see them on the soot-colored trees.

• Natural selection caused moths with white wings to become extinct.
