What are examples of Biston Betularia?

Biston betularia, commonly known as the peppered moth, is often cited as a classic example of natural selection. The two main forms of this moth are the light-colored (typica) and the dark-colored (carbonaria) variants. The dark-colored moths became more prevalent during the Industrial Revolution in England due to increased pollution, which darkened tree bark and provided better camouflage against predators. This phenomenon illustrates the impact of environmental changes on evolutionary processes.
