Detailed explanation-1: -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-2: -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. Click for more detail. As the trees darkened with soot, the light-colored moths were easier to see.

Detailed explanation-3: -Before 1850, most moths in England were light and lived in light-colored trees. When the industrial revolution hit England, black soot was released into the air and stuck to the trees, causing them to darken in coloration. During this time, light moth populations decreased and the number of black moths increased.
