Tree of Life Web Project
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world . On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history ( phylogeny ). Each page contains information about a particular group, e.g., salamanders , segmented worms , phlox flowers , tyrannosaurs , euglenids , Heliconius butterflies , club fungi , or the vampire squid .
