Color variation is the determining factor for the Natural selection of peppered moths in England.


Before the Industrial Revolution, pollution levels where considerably lower and the peppered moths that posses lighter coloration find it easier to camouflage on the lichen covered trees of the English forests. However, on the onset of the Industrial Revolution, the industrial emissions of the time turned most of the tree trunks, buildings and other surfaces into darker, soot-covered shades. Light-colored peppered moths were not able to blend in with this environment making them easy to spot to predators compared to their dark colored kins. Due to this, the darker-colored peppered moths survived better and had the opportunity to proliferate considerably more than those light-colored ones.
