Evolution of peppered moth

The peppered moth is a prime example of how evolution happens in our world with animals. In the past, before the industrial revolution, white peppered moths dominated the region near building cities and towns. Almost 98% of the moths were of this kind and only 2% were the black moths. This all drastically changed with the industrial revolution. This revolution of course was the creation of large factories that created building material that makes up our cities and towns today. The factories were a huge Negetive towards the environment due to the late amounts of pollution making light areas dark. What this did was it allowed the white moths to be more visible to predators and which then resulted in the % of white moths to drop down to nearly 5%! The number of black peppered moths increased insanely! This was because Now the blackened area by pollution was used as camouflage for those black moths and there % went up to 95! It crazy how evolution can effect a species isn't it?
