Evolution Answers

A population of moths consists of individuals that are white with black spots. Some are mostly white with just one tiny black spot, while others have lots of black spots with very little white but the majority are in the middle and are whitish with several black spots. These moths survive by hiding from predators on the sides of white birch bark trees. Suppose a coal factory starts to spew black pollution onto the white birch bark trees in the forest turning them black. Explain what is most likely to happen to the population of moths using the theory of evolution and the 4 principles of natural selection.
