Picture a giraffe nibbling leaves from the top of a tree, or a beaver adding a branch to its dam, or a peacock spreading its magnificent tail feathers. These and the millions of other organisms on Earth are the products of evolution. In this lesson you will go beyond a definition of what evolution is and examine how it works. You will study natural selection and mating patterns to see how these forces influence evolution.
