natural selection
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.

The peppered moth spends the winter in the soil where it pupates. Its binomial name is Biston betularia, and some of the countries it's found in are China, Russia, and Japan.
Variation in Biston betularia, like differences in coloration, can lead to evolutionary changes through natural selection. For example, if a light-colored moth is better camouflaged against a light background compared to a dark-colored moth, it may have a higher chance of survival and reproducing. Over time, this can result in a shift in the population towards the more advantageous coloration, due to increased survival and reproductive success of the better-camouflaged individuals.
