Evolution Practice

Natural selection is best described as

• a change in an organism in response to a need of that organism
• a process of nearly constant improvement that leads to an organism that is nearly perfect
• differences in survival rates as a result of different inherited characteristics
• inheritance of characteristics acquired during the life of an organism

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.
