  Linnaean taxonomy - Wikipedia, the free encyclopedia
A strength of Linnaean taxonomy is that it can be used to develop a simple and practical system for organizing the different kinds of living organisms.
This uniqueness and stability are, of course, a result of the acceptance by working systematists (biologists specializing in taxonomy); not merely of the binomial nomenclature in itself, but of much more complex codes of rules and procedures governing the use of these names.
"Taxonomy (the science of classification) is often undervalued as a glorified form of filing—with each species in its prescribed place in an album; but taxonomy is a fundamental and dynamic science, dedicated to exploring the causes of relationships and similarities among organisms.

Anthropologists have observed that taxonomies are generally embedded in local cultural and social systems, and serve various social functions.
Such taxonomies as those analyzed by Durkheim and Levi-Strauss are sometimes called folk taxonomies to distinguish them from scientific taxonomies that claim to be disembedded from social relations and thus objective and universal.
The most well-known and widely used scientific taxonomy is Linnaean taxonomy which classifies living things and originated with Carolus Linnaeus.

Scientific classification belongs to the science of taxonomy or biological systematics.
The approach he took to the classification of plants in his Historia Plantarum was an important step towards modern taxonomy.
Even though the parallel use of nomina trivialia and many-worded descriptive names continued until late in the eighteenth century, it was gradually replaced by the practice of using shorter proper names combined of the generic name and the trivial name of the species.

Linnaean taxonomy classifies living things into a hierarchy, starting with domains or kingdoms.
The most important aspect of this is the general use of binomial nomenclature, the combination of a genus name and a specific epithet ('tuberosa', in the example above), to uniquely identify each species of organism.

 Felid Taxonomy
The taxonomy currently in use for biological organisms, the Linnaean taxonomy, is more than 250 years old and even predates the theory of evolution.
This is a problem for the Linnaean system, and it happened because scientists of that time didn't have any way to know which organisms were actually related.

Taxonomies (using the term broadly to include even shallow taxonomies like subject headings) are critical tools for organizing information.
Although many taxonomy requirements documents and requests for proposals specify that the taxonomy include three (or even four or more) levels, the right number of levels is highly dependent on the particular content being organized.

 Responses from Kevin De Queiroz
Perhaps this was not a wise decision,because the term "evolutionary taxonomy" has been applied to avery different approach to taxonomy that was prevalent duringthe middle part of this century and is still embraced by somebiologists.
The problem with yourstatement that a universally accepted Linnean taxonomy wouldbe as useful as a phylogenetic taxonomy is that there is nouniversally accepted taxonomy (Linnean or phylogenetic), and abasic tenet of the current codes of nomenclature is to opposethe intellectual tyranny that would be needed to achieve one.

 Lecture: Life Classification, Dr. Rodrigue
At the species level, the Linnaean system designates a group of creatures so similar to one another, so closely related, that they reproduce with one another to make offspring that can survive and compete long enough to reproduce successfully in their turn.
So, taxonomy or systematics (the science of classifying organisms), which was a pretty sleepy subject when I went to college, is now hot with debate and has seen a great expansion of information that can be used for analyzing lineages, which is where this concern with cladistic analysis comes from: a.
Basically, just remember that taxonomy is a hot field now, with a great deal of debate and controversy going on, and that cladistic taxonomists are trying to come up with a binary approach to classification that creates unambiguous taxa (plural for taxon) that are demonstrably clades (all descendants of some basal group ancestor).

 Taxonomy Summary - Taxonomy Information
Taxonomy is the practice of classifying and naming biological organisms and groups of biological organisms.
Modern taxonomy originated in the eighteenth century with the work of a Swedish botanist, Carolus Linnaeus, who developed an organized hierarchical classification system that could be applied to all biological organisms.
Under the Linnaean system, all organisms are classified hierarchically into a series of groups from most inclusive to least inclusive.

The traditional, or Linnaean, taxonomy is still largely in favor among field workers, conservationists, and husbandry people.
Due to the sheer number of clades (all of which are generally assigned names), cladistic taxonomy becomes impractical when trying to simultaneously describe all of the world's 3,000 some odd reptile species, let alone the two to ten million species of plants, animals, and micro-organisms that are known or presumed to exist.

 BZN 58(2) General Articles & Nomenclatural Notes
Redundancy is introduced because the Linnaean hierarchy is equidistant: that is to say, every taxon is included in a continuity of ranks from Genus to Kingdom (although this is not stated as mandatory in the Zoological Code).
This is the annotated Linnaean system which by the use of a few conventions (Nelson, 1974; Patterson and Rosen, 1977; Wiley, 1979) can absorb the problems caused by rank yet allow those who wish to retain rank to do so for their own purposes.
Historically, in Linnaean Taxonomy apomorphy-based names are those which have caused most confusion, as Rowe and Gauthier (1992) point out in the context of the naming of Mammalia.

 Biological Nomenclature - Brummitt: Happy with the Present Code
A classification according to phylogeny is possible but is incompatible with the Linnaean system and would have a different structure without orders, families, genera etc. If such a system is considered desirable, it cannot replace the Linnaean system but should be parallel with it.
But whereas the Linnaean classification would be based on observable facts, a purely phylogenetic classification would be usually based largely on unverifiable suppositions.
Hennig's proposal to eliminate paraphyletic taxa was based on a failure to see the difference between the Linnaean hierarchy in which all taxa are nested in the next higher taxon, and a phylogenetic hierarchy which is not so nested, the lower levels of the hierarchy being not equivalent to the higher levels.

It is now generally accepted that classification should reflect the Darwinian principle of common descent, so that taxa include a single section of the evolutionary tree.
Since the 1960s a trend called cladistic taxonomy or cladism has emerged as a rival to more traditional phylogenetic classification.
In these approaches, the ranking system in Linnaean taxonomy may be abandoned, and a new formal code of nomenclature, the Phylocode, is currently under development.
