There is a moth in England called the peppered moth. BeforeBritainâs industrial revolution, these moths were usually âsalt andpepperâ colored. Because of their coloring, they blended in wellwith the tree trunks on which they tend to rest. The coloringhelped them hide from the birds that ate them. During the Britishindustrial revolution, industry expelled a lot of soot from theburning of coal into the environment. This soot darkened the treetrunks and it was noted that black colored moths were becomingpredominant. The idea is that with soot in the environment, blackcolored moths fair better than light colored moths. There is somedebate as to whether this is actually the case or not, but for thesake of this question, letâs assume it is.
In this context, review chapter 11.2 and the four observations. Inyour own words, explain how the concepts from the four observationsdiscussed in 11.2 relate to the evolution of the peppered mothdescribed above.
