The Tree of Life Web Project is a collection of information about biodiversity compiled collaboratively by hundreds of expert and amateur contributors. Its goal is to contain a page with pictures, text, and other information for every species and for each group of organisms, living or extinct. Connections between Tree of Life web pages follow phylogenetic branching patterns between groups of organisms, so visitors can browse the hierarchy of life and learn about phylogeny and evolution as well as the characteristics of individual groups.
From developers: "Please keep in mind that the Tree of Life website is still very much under construction. We are continuously adding new pages, but some important branches are still missing"
The website is well designed and easy to use, but is missing branches/information for a large portion of the tree of life. This site is useful for learning about the tree of life or if the Users organism of interest is present in the current tree.
