Cladistics (Greek: klados = branch) is a branch of biology that determines the evolutionary relationships between organisms based on derived similarities. It is the most prominent of several forms of phylogenetic systematics, which study the evolutionary relationships between organisms. Cladistics is a method of rigorous analysis, using "shared derived traits" (synapomorphies: see below) of the organisms being studied. Cladistic analysis forms the basis for most modern systems of biological classification, which seek to group organisms by evolutionary relationships. In contrast, phenetics groups organisms based on their overall similarity, while approaches that are more traditional tend to rely on key characters. Willi Hennig (1913 - 1976) is widely regarded as the founder of cladistics.

As the end result of a cladistic analysis, treelike relationship-diagrams called "cladograms" are drawn up to show different hypotheses of relationships. A cladistic analysis can be based on as much or as little information as the researcher selects. Modern systematic research is likely to be based on a wide variety of information, including DNA-sequences (so called "molecular data"), biochemical data and morphological data.

uBio creates new XML Web Services
Tue, 15 Aug 2006 00:00:00 -0400
A new set of webservices was added to the current collection. The new XML webservices can be called via HTTP GET and POST requests and will return XML data structures. This new version of web services can be easily embedded within any web-based application without having to deal with setting up SOAP clients.
Missouri Botanical Garden's Tropicos database is indexed in NameBank
