In its 4.6 billion year history, Earth has undergone massive geologic and climatic changes and provided habitat to an ever-changing cast of life forms. To learn more about the origins and evolution of Earth and its inhabitants, investigate this extensive collection of resources.
The extensive evidence in support of both fact and theory of evolution comes primarily from studies of the fossil record, molecular sequences, and comparative anatomy. Here you'll find some pivotal resources, on the Web and in books and articles, that summarize the intersecting and overlapping lines of evidence for evolution.
If you're looking for information about how individual species arise, how systematists classify them, or how many species are currently living on the planet, you've come to the right place. For information about species extinction, see the Deep Time/History of Life page.
