Watching natural selection happen helps us see how species change over time. Here are a couple of examples:
Peppered Moths: In places where factories are, darker moths did better. They blended in with the trees covered in soot, making it hard for predators to see them.
Antibiotic Resistance: Some bacteria get tougher over time. When we use medicine to kill them, the strongest ones survive and keep growing. This shows how quickly they can change.
These examples show us that evolution is always happening. It's affected by things in the environment, which helps us understand how certain traits can become more or less common in animals and plants over many years.
