Unit 7: Life on Earth

It's possible, maybe even likely, that there is life elsewhere in the universe, but if there is life we haven't found it yet. What makes Earth unique in the solar system is not only that it has life but that it has such an incredible diversity of life forms. The origin of life, the evolution of a variety of life forms, and the evolution of life that can read this sentence is certainly unique in the universe.
