Peppered moths were once always a light color so they blended in with their surroundings. Then one day the forest was poluted and the peppered moths changed colors. They went from a light color to a dark, almost black color. Scientists have been trying to find out why they changed the color all of a sudden. SO a scientist had a bunch of dark moths and a bunch of light moths. He released some of thee dark and light ones in the light non polluted forest then He let some dark ones and some light ones into the dark polluted forest.
His results were that in the dark forest more dark moths survived than light moths. This is because birds would most likely find and go after the easy to see moths than the well camouflaged moths. He had the same result in the light forest, he started to think that pollution was the reason the moths changed color. They must have evolved to fit with their environment, to survive. Before the pollution black peppered moths were very rare to find in the light forest, so the pollution had to be the problem. It didn't stop and more moths were getting darker. The light moths lived closer to the country side, and the dark moths lived closer to the cities where there is pollution and they will blend. Once in a while you will see a dark moth in a light forest or a light moth in a dark forest. You have to think positive about the situation, if there was no pollution then the world wouldn't have a rare black peppered moth. Even though there is pollution maybe a new breed will appear and amaze the world like the dark peppered moths did.
