Let's take the example of the peppered moth. Before the Industrial Revolution, most peppered moths were light-colored, which helped them blend in with the lichen-covered trees and avoid predators. However, as pollution increased, the trees became covered in soot, making the dark-colored moths less visible to predators. This led to a higher survival rate for the dark-colored moths, which then reproduced and passed on their advantageous traits. Over time, the population of peppered moths shifted to predominantly dark-colored individuals, demonstrating the process of natural selection.

The peppered moth is a cool example of how nature changes things over time. Before the Industrial Revolution, most of these moths were light-colored. This was super helpful because they could blend in with the lichen-covered trees, which kept them safe from birds and other predators. But then, as pollution increased, soot started to cover the trees, making them dark. This new environment made the dark-colored moths harder to spot, so they had a better chance of not getting eaten. Because they were better at surviving, these dark moths could have more babies. Over time, more and more peppered moths became dark-colored instead of light-colored. This whole change shows us how natural selection works!
