Question

Dr. Kettlewelll predicted that clean forests would have _____________ colored moths, and polluted forests would have _________ colored moths.

Answer 1

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
