Taxonomic Hierarchy
Taxonomic Hierarchy
Basis of Classification:
Taxonomy deals with nomenclature, identification and classification of organisms. Nomenclature is naming the organisms. The correct name of an organism is determined following some scientific rules. This implies assigning an organism to a particular taxonomic group. Classification deals with the arrangement of organisms or group of organisms into categories according to a systematic plan. The categories used in classification are kingdom, phylum, class, order, family, genus and species. Species are the lowest division of the hierarchy. It involves interbreeding organisms. These living forms vary in shape, size, structure, function, etc. The variations in their appearance, body design and behavior form the basis of classification.
Taxonomic Hierarchy:
In taxonomic study an organism is given an appropriate place in a systematic framework of classification. The framework, by which taxonomic groups are arranged in a definite order from higher to lower categories, is called taxonomic hierarchy. In the animal and plant kingdom, the lowest category is species and the highest is kingdom. The grouping of organisms into these categories, i.e., species, genus, family, order, class and phylum is determined by their similar characters and their relationships.
It is possible to imagine the various levels of taxonimic classification as a kind of "family tree" for an organism. If the kingdom is analogous to the trunk of the tree, which taxonomic category would be analogous to the large limbs coming off that trunk ? | |||
