The two types of peppered moths are the light-colored form called typica and the dark-colored form called carbonaria. These moths became famous for illustrating natural selection during the Industrial Revolution in England.
The Industrial Revolution caused pepper moths to adapt to a darker color due to the soot and ash everywhere so that they could hide from predators better, which made the black to gray moth ratio pull towards black. After the Industrial Revolution was over however then the black peppered moths numbers started to decrease and the grayish peppered moths number began to increase. This is evidence of adaptation.The population of light-colored moths decreased and the population of dark-colored moths increased.
Peppered moths have not been "created" in the traditional sense. They are a species of moth that has evolved over time through natural selection and adaptation. Their coloration played a role in the famous example of industrial melanism during the Industrial Revolution in England.
Peppered moths are a certain species of moth that inhabited trees. when the industrial revolution came, it made a lot of the trees black. the moths had to keep themselves hidden from birds, so some of the moths turned a black/brown color. It almost looks like they have pepper on them. Most of the moths just migrated to a different location, keeping their light original color.
The population of light-colored moths decreased and the population of dark-colored moths increased.
During the industrial revolution, peppered moths with dark coloration had better camouflage on soot-covered trees, allowing them to avoid predation and survive to reproduce. Over time, the frequency of dark-colored moths increased due to their enhanced survival, demonstrating natural selection operating on the population.
About 98% of peppered moths were dark by 1900 due to industrial pollution causing trees to darken, making dark moths more camouflaged and increasing their survival rates.

The phenomenon of the peppered moth becoming black is a common example of evolution. Originally, the vast majority of peppered moths had light coloration which camouflaged them when on the light-colored trees and lichens where they normally rested. However, because of widespread pollution during the Industrial Revolution in England, many of the lichens died out, and the trees that peppered moths rested on became blackened by soot from factories. This caused the light colored moths to stand out against the dark background, so they were easily found and eaten by predators. At the same time, the dark-colored moths flourished because of their ability to hide on the darkened trees.
The peppered moth was found to have industrial melanism. This phenomenon occurred during the Industrial Revolution in England, where darker-colored moths were able to camouflage better against polluted, soot-covered tree trunks. As a result, the darker moths had a higher survival rate compared to lighter-colored moths.
Peppered moths serve as a classic example of natural selection, particularly during the Industrial Revolution in England. Before the revolution, the light-colored moths were more common due to their camouflage against lichen-covered trees, which protected them from predators. However, as pollution darkened the trees, the darker, melanic form of the moth became better camouflaged, leading to an increase in their population. This shift demonstrates how environmental changes can influence which traits are favored, resulting in changes in species over time.
