This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.
