GPT 3.5
Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce at a greater rate than those less adapted. This leads to the accumulation of favorable genetic traits in a population over time.
One example of natural selection is the evolution of the peppered moth in England during the Industrial Revolution. Prior to this period, the peppered moth had a light coloration, which allowed it to blend in with the light-colored lichen on tree bark. However, as industrial pollution darkened the trees with soot, the light-colored moths stood out and became more vulnerable to predators. Over time, a darker mutation of the peppered moth became more prevalent, as they were better camouflaged against the dirty tree bark. This is an example of natural selection favoring traits that increase an organism's survival and reproductive success in a changing environment.
