In the 1800's in the UK (England), lots of factories were burning coal and wood which put up a bunch of smoke and soot in the air. Well, most of this had to come down somewhere. The trees in this area were a light greyish brown color originally. There were these light colored moths called peppered moths - they were whitish color with some light grey spots here and there. They blended in perfectly with the trees. There were other moths of the same species with different colors, mostly dark grey with whitish speckles, those were often eaten off the trees because they were easy to see. As the soot fell over many many years, it stained the trees a dark brown - blackish color. NOW, those dark grey moths blended in perfectly, and the light colored moths acutally started to die off because the birds could see them easier, so they ate them. Over time, the dark colored moths became more in numbers. Check out this cool site I use with my students: http://www.biologycorner.com/worksheets/pepperedmoth.html
What else can I help you with?
What is the change that occurred in peppered moths is an example of what?
The change that occurred in peppered moths, where the dark-colored moths became more prevalent in polluted areas, is an example of industrial melanism. This phenomenon demonstrates how natural selection can drive changes in populations based on environmental factors, such as pollution causing the dark moths to be better camouflaged against soot-covered trees.
What are two types of pepper moths?
Black peppered moths and white peppered moths
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.
What animals eat peppered moths?
Lizards
What’s an external adaptation peppered moths have?
Peppered moths have Camouflage and Mimicry, the use of Camouflage is to hide from predators.
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.
Why is there an increase in the number of dark colored peppered moths occurred during the industrial revolution?
birds couldn't see the dark-colored moths on the trees darkened by industry.
How Charles Darwin used pepper moths?
Charles Darwin did not study peppered moths. The study of peppered moths and their evolution in response to industrialization was done by British biologist Bernard Kettlewell in the mid-20th century, not by Darwin. Kettlewell's research on peppered moths played a key role in illustrating natural selection in action.
Are all of the peppered moths of the same species?
yes
