Timetree of Life

The Timetree of Life contains electronic files of articles and figures from the book The Timetree of Life (2009), Oxford University Press, and a wall poster. These resources are copyrighted but are provided free for personal, research, or educational use.

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results. Check out the "resources" section, too, for links to other sites that focus on evolutionary history.
