Detailed explanation-2: -When the environment changed, due to pollution, the moth population shifted because light-colored moths became easier to see so they were eaten more often. Organisms that survive have a better chance of reproducing so the population continues to grow.

Detailed explanation-3: -Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat.

Detailed explanation-4: -The Peppered Moth is widespread in Britain and Ireland and frequently found in ordinary back gardens, yet its amazing story has made it famous all over the world. It is one of the best known examples of evolution by natural selection, Darwin’s great discovery, and is often referred to as ‘Darwin’s moth’.
