Peppered moths vary from almost white and dark dots ib the wings to almost completely black. Before the Industrial Revolution in the late 1800's, the moth seen most often around cities was light-colored. During the Industrial Revolution, factories filled the air with pollutants. The pollutants settled on tree trunks, killing the lichens living on the trunks and turning light-colored bark to dark gray. Scientists noticed a change in the moth population: they found more dark-colored moths than light colored moths.
This example shows that variation in a population is important. Explain why.
If there were no variation and all moths were light colored, they would have been more easily seen and preyed upon by animals that eat them. That would have been the end of the story. But because there was variation, a dark colored version and a light colored version, when the bark became dark the light ones were still eaten because they were more visible but the darker colored ones blended in with the dark bark and were overlooked by the predators. So the population of dark colored ones rose. The moth population continued because of variation.
