A protective coloring has been developed to avoid visions of animals such as night moths. It is well known in Britain what happened during the industrial revolution: due to the smoke of the factories, along with the belzte of the trees, cocks proliferated. Those who used to have a light color were normal, but on black trunks they were easier to see, so predators saw them easily and greatly reduced.

Although some discussions and research have been conducted on this evolutionary mechanism, the phenotype change associated with the frequency of predation has never been demonstrated. However, a strange research has recently been conducted at the University of Nebraska in the United States. This research has used virtual images of chickens, an algorithm that controlled phenotype changes and real birds. Thus, scientists have discovered that moths evolve into phenotypes difficult to detect for birds.
