Biological evolution is a powerful and important process. It is a process which, over billions of years, gradually selects the organisms that are better adapted to their environments, and in this way takes advantage of random mutations to continuously change life and make all living organisms in existence be the way they are.

Evolution is not a finished event, of which we, humans, are the final product. Rather, it is a continuing process which has been changing and forming life on earth for billions of years and continues to do so for as long as organisms are being born, dying, and competing for what they need to survive and reproduce.

The purpose of this web site is to teach and explain what evolution is and how it works. This web site is designed for children, but can be used by teachers or by anyone who wants to learn about this amazing process of life.
