Biological adaptation over the course of time is the result of natural selection. natural selection ensures that the most fit and most adaptable organisms survive and reproduce. originally, 98% of peppered moths had a light coloring which provided good camouflage against predators. before the industrial revolution, a dark variation of the peppered moth made up 2% of the species.

during the industrial revolution, soot and pollution from factories made the trees and vegetation darker. after the industrial revolution, the dark colored peppered moths made up 95% of the population.
