Almost anything animate objects, inanimate objects, places, and events may be classified according to some taxonomic scheme. Mathematically, a taxonomy is a tree structure of classifications for a given set of objects. At the top of this structure is a single classification - the root node - that applies to all objects. Nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. So for instance in Carolus Linnaeus's Scientific classification of organisms, the root is the Organism (as this applies to all living things, it is implied rather than stated explicitly). Below this are the Kingdom, Phylum, Class, Order, Family, Genus, and Species, with various other ranks sometimes inserted. Some have argued that the human mind naturally organizes its knowledge of the world into such systems. This view is often based on the epistemology of Immanuel Kant Anthropologists have observed that taxonomies are generally embedded in local cultural and social systems, and serve various social functions. Perhaps the most well-known and influential study of folk taxonomies is

Taxonomy From New World Encyclopedia Jump to: navigation search Previous (Taxon) Next (Tea house) Taxonomy is the science of describing, naming, and classifying living and extinct organisms (the term is also employed in a wider sense to refer to the classification of all things, including inanimate objects, places and events, or to the principles underlying the classification of things). The term taxonomy is derived from the Greek taxis ("arrangement;" from the verb tassein, meaning “to classify”) and nomos (“law” or “science,” such as used in “economy”). An important science, taxonomy is basic to all biological disciplines, since each requires the correct names and descriptions of the organisms being studied. However, taxonomy is also dependent on the information provided by other disciplines, such as genetics, physiology ecology , and anatomy Naming, describing, and classifying living organisms is a natural and integral activity of humans. Without such knowledge, it would be difficult to communicate, let alone indicate to others what plant is poisonous, what plant is edible, and so forth. The book of Genesis in the Bible references the naming of living things as one of the first activities of humanity. Some further feel that, beyond naming and describing, the human mind naturally organizes its knowledge of the world into systems.

Taxonomy: Classifying Life At least 1.7 million species of living organisms have been discovered, and the list grows longer every year (especially of insects in the tropical rain forest). How are they to be classified? Ideally, classification should be based on homology ; that is, shared characteristics that have been inherited from a common ancestor . The more recently two species have shared a common ancestor, the more homologies they share, and the more similar these homologies are. Until recent decades, the study of homologies was limited to anatomical structures and pattern of embryonic development. However, since the birth of molecular biology, homologies can now also be studied at the level of proteins and DNA DNA-DNA Hybridization Chromosome Painting Comparing DNA Sequences Anatomical homology: an example The figure shows the bones in the forelimbs of three mammals: human, whale, and bat (obviously not drawn to the same scale!).

Schistosomiasis Research Group Home Projects Group Publications ... Other Helminths Helminth Taxonomy - Phylum Nematoda These helminths are the roundworms, having elongated cylindrical unsegmented bodies, covered in a tough inert cuticle, which may, depending on the species, have striations, lateral spines, terminal expansions or other modifications. Internally the cuticle is formed from an underlying hypodermis, (which may either be a syncytium or made up of cells),which has four longitudinal thickenings, the two lateral thickenings containing excretory canals. Over this is a muscular layer, lining the fluid filled pseudocoelomate body cavity (i.e.. not lined with an epithelium as in a true coelom), within which the internal organs are held. For more details go to the Nematode Biology Pages within this site. In almost all cases there are separate sexes, sexual reproduction occurring in the definitive host in parasitic species. Note: The classification and taxonomy of nematodes, as has been pointed out, is under continual discussion, and is thus rather confusing. For example, many older systems do not have a phylum Nematoda, the nematodes being grouped in the class Nematoda, part of a much larger grouping, the phylum Nemathelminthes, and including the Acanthocephala, (now also grouped in their own phyla). The system used here has been adapted from that of A. M. Dunn, in his book "Veterinary Helminthology" (William Heinemann Medical Books Ltd, 1978), an excellent introduction to veterinary helminthology.

RULES OF TAXONOMY Every known living organism on Earth is classified and named by a set of rules. Those rules are used by all scientists around the planet. The names are called scientific names, not common names. Common names are the ones you might use when talking with your friends. You call your pet a dog or a cat (the common name). Scientists call those animals by a set of several names like Canis familiarus . That's a dog. SCIENTIFIC NAMES Scientific names follow a specific set of rules. Scientists use a two-name system called a Binomial Naming System . Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species. The first word is capitalized and the second is not. A binomial name means that it's made up of two words (bi-nomial). Humans are scientifically named Homo sapiens . You may also see an abbreviation of this name as H. sapiens where the genus is only represented by the first letter. TAXONOMY The taxonometric way of classifying organisms is based on similarities between different organisms. A biologist named Carolus Linnaeus started this naming system. He also chose to use

BIOLOGICAL DIVERSITY: CLASSIFICATION Table of Contents Biological Diversity and Classification Nomenclature Construction of Phylogenetic Trees The Kingdoms of Life ... Links Biological Diversity and Classification Taxonomy is that branch of biology dealing with the identification and naming of organisms. The ancient Greek philosopher Aristotle apparently began the discussion on taxonomy. British naturalist John Ray is credited with revising the concept of naming and describing organisms. During the 1700s, Swedish botanist Carolus Linneus classified all then-known organisms into two large groups: the kingdoms Plantae and Animalia. Robert Whittaker in 1969 proposed five kingdoms: Plantae, Animalia, Fungi, Protista, and Monera. Other schemes involving an even greater number of kingdoms have lately been proposed, however most biologists employ Whittaker's five kingdoms. Recent studies suggest that three domains be employed: Archaea, Bacteria, and Eukarya. The classification of a rose is shown in Figure 1, while that of a warbler is illustrated in Figure 2. Figure 1. Taxonomy of a selected plant species. Note the increasing inclusivity of the "higher" taxonomic ranks. Kingdoms have a great deal more types of creatures in them than do species.

Taxonomy Taxonomy Definition noun (1) The science of finding, describing, classifying, and naming organisms , including the studying of the relationships between taxa and the principles underlying such a classification. (2) The classification of organisms in a hierarchical system or in taxonomic ranks (e.g. domain kingdom phylum or division class genus species ) based on shared characteristics or on phylogenetic relationships inferred from the fossil record or established by genetic analysis. Supplement For example, organisms are classified into clades (i.e. a taxonomic group of organisms based on homologous features derived from a common ancestor) in phylogenetic taxonomy Word origin: from Greek taxis , arrangement, order + - nomia , method, from - nomos , law, managing, from nemein , manage.
