Explain natural selection with an example.
Natural selection leads to survival of the fittest; an example is the peppered moth adapting to pollution.
Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce, passing those traits to the next generation.
Example:
The classic example of natural selection is the evolution of the peppered moth in industrial areas. During the Industrial Revolution, darker moths had a survival advantage as they were better camouflaged against soot-darkened trees, leading to an increase in their population.
