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.
The population of light-colored moths decreased and the population of dark-colored moths increased.
The peppered moths of England underwent directional selection following the Industrial Revolution. Prior to the pollution caused by industrialization, lighter-colored moths were more common and better camouflaged on the light-colored tree trunks. However, as pollution darkened the tree trunks, the darker moths had a survival advantage and their population increased.

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 melanic form of the peppered moth is darker in coloration compared to the typical light-colored form. This dark coloration is a result of a genetic mutation that causes an increase in the production of melanin pigments in the moth's wings. The melanic form of the peppered moth became more prevalent in polluted areas during the industrial revolution due to its increased camouflage on darkened tree trunks.
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.

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 peppered moths of England underwent directional selection following the Industrial Revolution. Prior to the pollution caused by industrialization, lighter-colored moths were more common and better camouflaged on the light-colored tree trunks. However, as pollution darkened the tree trunks, the darker moths had a survival advantage and their population increased.
In 1850, the peppered moth (Biston betularia) exhibited a notable variation primarily between its two color morphs: the light-colored, speckled form and the darker, melanic form. This variation was influenced by environmental factors, particularly the industrial pollution in certain regions of England, which darkened tree bark and favored the survival of the darker moths. The observation of these color variations became a key example in studies of natural selection and adaptation, particularly during the Industrial Revolution.
Because before the industrial revolution, the bark of the trees they lived on was light, therefore the dark ones could be easily seen and eaten by predators, causing only the lighter ones to survive. When the industrial revolution came about, the trees near factories were covered in soot and blackened by the pollution, therefore the darker moths couldn't be seen and eaten so they survived wheras the lighter moths could be seen and eaten.
To return the environment of the peppered moth to its original state, conservation efforts could focus on reducing pollution levels, restoring habitats, and implementing measures to control industrial emissions. Additionally, promoting biodiversity and reducing light pollution in urban areas can also help create a more suitable environment for the peppered moth population to thrive.
