Detailed explanation-1: -When the environment changed, due to pollution, the moth population shifted because light-colored moths became easier to see so they were eaten more often. Organisms that survive have a better chance of reproducing so the population continues to grow.
Detailed explanation-2: -Before 1850, most moths in England were light and lived in light-colored trees. When the industrial revolution hit England, black soot was released into the air and stuck to the trees, causing them to darken in coloration. During this time, light moth populations decreased and the number of black moths increased.
Detailed explanation-3: -The light moths blended in with the light-colored trees. However, the Industrial Revolution changed the tree colors. After the pollution from the Industrial Revolution started affecting trees, most of the collected peppered moths were of the dark form.
Detailed explanation-4: -Q. Why did the population of peppered moths in England change from the light variation to the dark variation after the Industrial Revolution? The soot from industrial revolution caused the light peppered moth to fly away, and only the dark variation was left.
