LS4.3 Genetic Variation

During the Industrial Revolution that lasted from 1760-1840, it was observed that the peppered moth, Biston betularia f. typica, found living on trees with light colored bark around the industrial city of Manchester started to change from a light colored from with minimal dark marking to a completely black moth. It has been observed in modern times that the black moth, Biston betularia f. carbonaria, is slowly being replaced by the original light-colored moth.

1)    What precipitated the change in the moths to change color from light to dark?

• The moths changed color due to the change in the color of the trees caused by industrial pollution
• Constant rain splashing mud onto the trees and buildings

• The pollution from the coal factories made the sky permanently dark so the darker moths were harder to find by predators

• Both 1st and 2nd answers

Why was the change to black beneficial to the black moths?

 

• They were harder for predators to find against the soot-stained tree

• Predators foudn the light-colored moths more easily, so they were eaten.

• The light-colored moths died due to the pollution

• Both A and B

It has been observed in modern times that the black moth, Biston betularia f. carbonaria, is slowly being replaced by the original light-colored moth.

Why are the peppered moths slowly returning to their original light coloration?

• All the black moths have been eaten by predators because they are more tasty.

• Since coal pollution has been reduced trees and buildings are no longer covered in soot.

• Nature changed the moths to black because the light-colored ones are boring

• All of the above

Why did Darwin's finches develop different beak types
