nomenclature

 [no´men-kla″chur]
terminology; a classified system of technical names, such as of anatomical structures or organisms.
binomial nomenclature the nomenclature used in scientific classification of living organisms in which each organism is designated by two latinized names (genus and species), both of which must always be used because species names are not necessarily unique. note: The genus name is always capitalized, the species name is not, and both are italicized, e.g., Escherichia coli. When a name is repeated the genus name may be abbreviated by its initial, e.g., E. coli.

lin·nae·an sys·tem of no·men·cla·ture

binomial nomenclature

n.
The scientific naming of species whereby each species receives a Latin or Latinized name of two parts, the first indicating the genus and the second being the specific epithet. For example, Juglans regia is the English walnut; Juglans nigra, the black walnut.

binomial nomenclature

in this the FOVEA, an area of acute vision, is of particular importance. Binocular vision results in a stereoscopic or 3-D effect, the slightly different positions of the two eyes being important in that they view the object from slightly different angles.

binomial nomenclature

the basis of the present scientific nomenclature of animals and plants, each of which is given a generic name followed by a specific name, in Greek, Latin or often Latinized English. The generic name invariably has an initial capital letter, and the specific name, even if it is the name of a person, an initial small letter, both names being in italics, or underlined. Thus the robin is named Erithacus rubecula. All scientific names used before the publication of the 10th edition of LINNAEUS'S Systema Naturae (1758) are no longer applicable, and the names given since then have priority by date as a rule, the earliest name for an organism being given preference over others. Often the scientific name is followed by the name of the person allocating the name and the date, e.g. Erithacus rubecula (L.) 1766. L. is an abbreviation for Linnaeus, and the brackets indicate a change from the genus in which he originally placed it; where genera and species are redefined, change of generic name is allowable. The robin was originally named Motacilla rubecula L. 1766. Motacilla is now the genus including wagtails, a group not closely related to robins which were subsequently placed in the genus Erithacus.

I believe the lack of information content from the name itself in a rankless approach to nomenclature and the serious risk of content change associated with the explicit phylogenetic definitions make this system inappropriate as a replacement for the current system of biological nomenclature. I believe phylogenetic nomenclature would be less useful to most users and, as Bowker and Star (1999: 7) noted, "[a]ny information systems design that neglects use and user semantics is bound for trouble down the line--it will either become oppressive or irrelevant,"

Stability of names is the only criterion of interest to de Queiroz, but it can hardly be the only relevant criterion in evaluating a system of biological nomenclature. Thus this example cannot be viewed as anything but weak.
Proposals to discard the current systems of biological nomenclature and replace them with a so-called phylogenetic taxonomy received considerable publicity for about a decade without any specific details on implementation of the replacement system (see Nixon & Carpenter, 2000).
