Why did dark moths have a survival advantage?

Answer 1

Dark moths had a survival advantage during the industrial revolution because their dark coloration allowed them to blend in better with the soot-covered trees, making them less visible to predators. As a result, they were more likely to survive and reproduce, passing on their dark coloration genes to their offspring. Over time, this led to an increase in the population of dark moths and a decrease in the population of light-colored moths.
