ETI is a non-governmental organisation in operational relations with UNESCO. Their mission is to develop scientific/educational computer-aided information systems, to improve general access to, and to promote use of taxonomic and biodiversity knowledge

An up-to-date historical cross-referenced classification of life based on original authorative scientific literature.

A project containing information about the diversity of organisms on Earth, their history, and characteristics. The information is linked together in the form of the evolutionary tree that connects all organisms to each other.

Authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world.

About taxonomy and systematics at the University of Glasgow, with links to other internet resources on these subjects.

A flexible format for encoding taxonomic descriptions for computer processing. It can be used to produce natural-language descriptions, conventional or interactive keys, classifications, and information-retrieval systems.

Includes photos of more than 50,000 plant, palm, cycad and other cultivated tropical plants from Florida and taxonomic information on grasses, especially bamboos, and other economically important and interesting plants.

Probably the most comprehensive

A project examining the phylogenetic tree of life and all of its features, with information and pictures for every class and an interactive, dynamic hierarchy.

Joe Felsenstein`s suite of programs implementing perhaps the widest range of phylogenetic inference package. The most widely distributed phylogeny software. Includes distance, likelihood and parsimony methods for a wide range of different types of data,

The NCBI Taxonomy Homepage

A networked information service for biological information resources, based upon the Taxonomic Name Server, a thesaurus of taxonomic information.

A relational database of phylogenetic trees and the data matrices used to generate them from published research papers. Includes animals, plants, and fungi.

Multiple Alignment Resources

Database management system for recording taxa, specimens, characters, and images. Also serves as an interactive identification system.

A global network of country-owned collaborative LOOPs to support national programs for biosystematics to support goals in areas such as sustainable development and pest management.

Information of interest to systematists and other organismic biologists such as biological collections, taxonomic files, directories and ListServ archives, computer programs, reports by standards bodies (IOPI, ASC, and SA2000), and access to on-line

Supporting material for the "Evolution" TV series. Includes informative activities.

Extensive and interactive educational resource providing information on biological and cultural evolution, language development, and philosophy.

This article directly addresses the scientific evidences in favor of macroevolutionary theory and common descent.
