The Tree of Life Web Project (tolweb.org) is an expansive, collaborative digital encyclopedia of life, designed to illustrate the evolutionary relationships among all living organisms. The project presents a phylogenetic "tree of life," where each branch represents a lineage of species connected through evolutionary history. The site offers detailed pages on various groups of organisms, including descriptions, images, and information on their evolutionary relationships, biology, and ecological roles. The Tree of Life Web Project is continually updated with contributions from scientists, making it a dynamic and authoritative resource for understanding biodiversity and evolution. It serves as a valuable educational tool for students, educators, and anyone interested in the natural world.
