The gene for dark coloration in peppered moths likely originated as a mutation in the population. This mutation provided an advantage in industrial areas where soot-darkened trees made lighter-colored moths more visible to predators. As a result, the darker moths had higher survival rates and reproductive success, leading to an increase in the frequency of the dark coloration gene in the population over time, a phenomenon known as natural selection.

What are the two types of peppered moths?
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.
How did natural selection affect peppered moths?
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.

What’s an external adaptation peppered moths have?
Peppered moths have Camouflage and Mimicry, the use of Camouflage is to hide from predators.
When was Peppered moth created?
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.
Why are peppered moths called 'peppered'?
Peppered moths are so named for their appearance with their many black spots. The larvae thrive by eating the leaves from a variety of trees like the oak tree.

How is the example of peppered moths different from Darwins theory?
The example of peppered moths is not really different from Darwin's theory, it is the same concept. The only difference is that peppered moths live in the same habitat, where as Darwin's finches live in different habitats, which drove the evolution of their different beak shapes. The peppered moths have adapted to blend into their environment so they're not as easily caught.
What happened to the peppered moths environment?
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.

Can you think of an experiment to test the hypothesis that being light or dark makes a difference in the survival rates of peppered moths?
I remember years ago reading up about industrialisation and how pollution caused many trees and whatnot to darken considerably with the smog, exposing the light peppered moths and giving the dark peppered moths a better chance of survival.
