taxonomy

 [tak-son´ah-me]
the orderly classification of organisms or lists into appropriate categories (taxa), with application of suitable and correct names. adj., adj taxonom´ic.
numerical taxonomy a method of classifying organisms solely on the basis of the number of shared phenotypic characters, each character usually being given equal weight; used primarily in bacteriology.

tax·on·o·my

(taks-on'ŏ-mē),
The systematic classification of living things or organisms. Kingdoms of living organisms are divided into groups (taxa) to show degrees of similarity or presumed evolutionary relationships, with the higher categories being larger, more inclusive, and more broadly defined, and the lower categories being more restricted, with fewer species more closely related. The divisions below kingdom are, in descending order: phylum, class, order, family, genus, species, and subspecies (variety). Infra- and supra- or sub- and super- categories can be used when needed; additional categories, such as tribe, section, level, group, etc., are also used.
[G. taxis, orderly arrangement, + nomos, law]

taxonomy

(tăk-sŏn′ə-mē)
n. pl. taxono·mies
1. The classification and naming of organisms in an ordered system that is intended to indicate natural relationships, especially evolutionary relationships.
2. The science, laws, or principles of classification.
3. An ordered arrangement of groups or categories: a taxonomy of literary genres.

taxonomy

The science or principles of biological classification and the assignment of appropriate names to species.

taxonomy

the study of the CLASSIFICATION of organisms. Classical taxonomy involves the use of morphological features, cytotaxonomy the use of somatic chromosomes, experimental taxonomy involves the determining of genetical interrelationships, and numerical taxonomy involves quantitative assessments of similarities and differences in an attempt to make objective assessments.
