Why did bark moths have a survival advantage?

Bark moths, such as the peppered moth, gained a survival advantage through their ability to camouflage with their environment. During the Industrial Revolution, the darkening of tree bark due to soot made lighter-colored moths more visible to predators, while darker moths blended in better. This natural selection favored the dark-colored moths, allowing them to survive and reproduce more effectively in polluted areas. Consequently, their population increased, demonstrating the role of environmental changes in evolutionary adaptations.
