Originally Answered: What is a Taxonomic Order/Family?
Taxonomy is a system of classification used in biology. It is used to group organisms into ranks that describe their relationships to other organisms. The rankings are structured to illustrate the relatedness of similar organisms from the most inclusive*** such as the Kingdom of animalia - animals, down to the most specific rank that relates to one animal within that Kingdom - the species. These ranks are (in order from most generalised to most specific) Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. For a more detailed account of biological taxonomy, read this link...
*** actually the most inclusive rank of all is Domain, but as an introduction the familiar Kingdom of animalia (animals) seemed more appropriate as an illustration.
The taxonomic profile of the arctic wolf is shown below the pic on the right, at the top of this link...
Species: Canis lupus
Subspecies: Canis lupus arctos
Note that when I listed the taxonomic ranks, I included Domain which is not mentioned on that article. As is often the case, Domain is omitted because the rank is so all-inclusive as to become something of an irrelevance when describing an organism. Nonetheless, it is the first and most inclusive rank in biological taxonomy. Note also the final listing for your arctic wolf - subspecies. Subspecies is not one of the main ranks but rather a sub-rank of the species utilised to denote the existence of 2 or more variations within that parent species. The parent species of your arctic wolf (Canis lupus arctos) is easy to determine (other than reading above !) if you know the following.
The species name is a binomen - 2 names, subspecies name is a trinomen - 3 names. The species name you will note is the genus name followed by the specific name of the species...genus - Canis, specific or species name - lupus...together giving what is known as the scientific name of the species - Canis lupus. If the species has a number of subspecies, then the exact animal in question will be denoted by a 3rd name, arctos in this case, to give the trinomen Canis lupus arctos - the arctic wolf. One final point, you will see that all the names at each rank are capitalised except for the specific (species) and the subspecific (subspecies) names - lupus and arctos respectively. This is worldwide biological convention as laid down in the zoological authority ICZN, International Code of Zoological Nomenclature. This document is the global authority for all things to do with zoological taxonomy.
By the way, the parent species Canis lupus is the grey wolf, the common ancestor of all domestic dogs.
