The Tree of Life WEb Project

The Tree of Life is a collaborative web project, produced by biologists from around the world. On more than 2000 World Wide Web pages, the Tree of Life provides information about the diversity of organisms on Earth, their history, and characteristics.

Each page contains information about one group of organisms (for example, the Coleoptera page gives information about all beetles, the Salticidae page about jumping spiders, the Cephalopoda page about squids, octopi, and related molluscs, and the Fungi page about fungi). Individual Tree of Life pages are linked one to another in the form of the evolutionary tree that connects all organisms, with the pages branching off from a group's page being about subgroups. For example, the links from the page on frogs leads one to pages on individual families of frogs, and eventually up to some individual species of frogs:
