The great Tree has roots, a trunk, stems, and branches that connect each organism to all others. Coordinated and edited by David R. Maddison of the University of Arizona, this attractive and expertly managed site has over 1300 pages housed on 20 computers in four countries, and is authored by biologists from around the world. Originally intended for professionals, the site has evolved into one for non-biologists as well. Searchable.
