The Tree of Life Web Project is an ongoing Internet project providing information about the diversity and evolutionary relationships of life on Earth. This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The goal of the Tree of Life Web Project 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.
