I think evolution is when something, an animal changes, or plant. It’s a change so they can fit more where they’re living, to help them to survive a little bit more. If they lived next to sea and there wasn’t any other food, they would have to learn how to swim and how to dive for food, to get fish out of the water. When an animal has a child, I think it changes just a tiny bit, because it changes so it can survive. I think it just happens.
