Probably due to the lack of pollution around. Once the human race discovered fire, there was an increase in soot & carbon particles in the air, which darkened surfaces. This made the lighter mothWhy_do_you_think_the_lighter_variety_of_the_peppered_moth_was_more_common_originallyto predators. The darker colouration evolved to help give it camouflage when it rests on trees.

Can you think of any real-life examples of the woolybooger where one species has a definite advantage over?

Dark peppered moths in England have definite advantage over light peppered moths because they have the ability to blend in with the dark sooty trees affected by pollution. The light peppered moths are at a disadvantage because they stand out to predators (birds).


Can you think of an experiment to test the hypothesis that being light or dark makes a difference in the survival rates of peppered moths?

I remember years ago reading up about industrialisation and how pollution caused many trees and whatnot to darken considerably with the smog, exposing the light peppered moths and giving the dark peppered moths a better chance of survival.


The british have instituted pollution controls on factories how do you think this will affect the evolution of the peppered moth?

The pollution controls on factories will likely improve air quality, resulting in reduced pollution levels. This may lead to a decrease in the advantage of the dark-colored peppered moths, as the lighter-colored moths may become better camouflaged against cleaner backgrounds. Over time, this could potentially shift the balance back towards the lighter-colored moths.
