The evolution of the taxonomy or Systématique
We owe the modern taxonomy to Linné, Swedish naturalist 18th century. It was in the 19th century appears that the evolution of species including by J. B. Lamarck and C. Darwin.
The current classification is based primarily on the morphology and phylogeny But research on the molecules and DNA as well as biology and ethology upset current knowledge.

Notions of Taxonomy
The classification system is a zoological hierarchical whose basic unit is the case. The Animal Kingdom and runs until this unit. For more information: TABLE No. 1
A classification according to a likeness (morphologique, phylogeny, genetic) located in an animal categories increasingly limited. For more information: TABLE No. 2
The names used in classification are still cast in scientific terms to avoid confusion between species. Latin was used as a language international stable. Thus a species always written in this form, with an example for the Lion:
Panthera leo : First word is Genus (Panthera)and the 2nd to the species (leo)
The species are described Code set by the ICNZ (International Commission for the Nomenclature Zoologique)
The classification this site is a synthesis of several modern Taxonomies

The Synonyms
A species or subspecies may have several scientific names (Latin name = or taxa) to designate. These names are created by systematists for two main reasons:
* Each assign a name to a species by ignorance of the work of other
* Each publish almost simultaneously homotypic taxa under different names
The scientific community can agree to do that than keep all names created. But generally, only one taxa (the oldest) is designated as a priority by the International Commission on Zoological Nomenclature. Other names are considered "synonymous" (= junior synonym).

DNA as a referee
The status of a species or subspecies, as a species or subspecies, is not always clearly defined. These taxa words, revision is due to:
* A number of individuals observed or found in nature, considered too low to confirm a hypothesis
* Research, studies and inadequate or incomplete
* Disagreements between scientists
Molecular biology is now used to confirm the status.

Unnamed Species
Each year new species are discovered thanks to specimens observed or collected in the wild, especially during scientific expeditions.
Their classification is subject to further investigation and pending these species are described as "unnamed".
