Phylum Class Order Family Genus Species |
In the Linnean system (and
taxonomic systems based on it), a Class is the taxonomic category between
Phylum
and Order. A class is a major group of organisms,
e.g. Mammalia,
 Reptilia,
Gastropoda,
Insecta,
etc that contains a large number of different sublineages, but have shared
characteristics in common (e.g. warm-blooded, fur, mammary galands in female
in the case of mammals, six legs and three body parts in the case of Insects,
etc). As with all the groupings whether a group of organisms ranks
as a class or not is a subjective decision, although usually based on the
traditional status of that group in earlier literature. The cladistic
revolution has caused a reappraisal of these rankings, and rejecton or
modification of many of these rankings. |
Originally Linneus
divided the Animal Kingdom into six
classes.
Many more have been proposed
since then
