Detailed explanation-1: -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-2: -The light moths blended in with the light-colored trees. However, the Industrial Revolution changed the tree colors. After the pollution from the Industrial Revolution started affecting trees, most of the collected peppered moths were of the dark form.
Detailed explanation-3: -The researchers demonstrated that the pale moths are safer from predators when there is less pollution, while darker moths have a better chance of survival when the air is more polluted. The research confirms Darwin’s theory of evolution.
Detailed explanation-4: -The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.
