Evolution is change that happens over a really long time. Evolution varies from many different things. It could be the population or how we look and act. Some people believe that this has been taking place for the past 300 million years. Others don't believe in it at all. Scientists believe that evolution is the changing of a animal or plant over millions of years. The organisms in these animals and plants take a very long time to change. The things that they change vary from animal to animal or plant to plant.
