Detailed explanation-1: -Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection. Over 100 other species of moth were observed to darken over time in polluted forests. Scientists call this effect industrial melanism.

Detailed explanation-2: -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.

Detailed explanation-3: -Wing-color changes in peppered moths are a common example of what scientists refer to as natural selection. In it, organisms develop random mutations. Some of the gene changes will leave individuals better suited-or adapted-to their environment. These individuals will tend to survive more often.

Detailed explanation-4: -Moths’ ability to adapt to their environment through different color patterns allows them to camouflage against would-be predators. As environmental standards have reduced pollution in many parts of the world, moths are now breeding out the darker coloring to better adapt to their changing environment.

Detailed explanation-5: -Natural selection was the best explanation for the change in the moth population over time.
