Answer 2

Evolution is the change in allele frequency in a population over a period of time.

In the population of peppered moths, like populations of any species, there is variation. This variation can lead to changes in allele frequency throughout the population if a certain allele has a reproductive advantage.

Prior to the Industrial Revolution, lighter colored moths generally lived longer and had more offspring. Some of those offspring were darker, but most were light.

With increasing pollution, the darker moths enjoyed a natural advantage and began surviving longer and reproducing more than the lighter moths.

It is a classic example of natural selection at work.

Answer 3

It doesn't! They didn't change species. The moths just adapted to the enviroment. If I remember right, the whiter moths blended into the color of the bark of the trees they rested upon making the darker one stand out to be picked off by predators. During the industrial revolution the trees became darker due to air pollution making the lighter ones a better target.
