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.
Providing the scientific basis for effective conservation, NatureServe and its network of natural heritage programs are the trusted source for information about rare and endangered species and threatened ecosystems
This tree is constructed from an analysis of small subunit rRNA sequences sampled from approximately 3,000 species from throughout the Tree of Life. The species were chosen based on their availability, but most of the major taxonomic groups were included,
