Natural selection is nature’s way of making life better. Here’s how it works when living things adapt:
Variation: In a group of animals or plants, some things are different. For example, imagine a group of birds that have beaks of different sizes.
Survival: The traits that help an animal or plant survive in its environment are very important. For instance, birds with bigger beaks may find it easier to crack open hard seeds when there isn’t much food available.
Reproduction: The birds that have the helpful traits usually live longer and have more baby birds. This means they can pass those good traits on to their young.
Over time, these helpful changes become normal and shape the whole species!
