Basically what I already knew about Evolution, is that it is the process by which a species changes over time in order to adapt to its surroundings. This is achieved through natural selection, the process by which specific traits survive and spread in a species. For example, if two mice were to live in an area that is extremely cold, and one of the mice had longer hair, then the mouse with the longer hair would survive the cold, breed, and produce more mice with the longer hair. I also knew that both of these theories came from Darwin, who came up with the Ideas while studying animals on the Galapagos islands.
