Domain Biology Biology Dictionary Intermediate minor rankings are not shown. in biological taxonomy, a domain ( dəˈmeɪn or doʊˈmeɪn ) (latin: regio[1]), also dominion, [2] superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. it was introduced in the three domain system of taxonomy devised by carl woese, otto kandler and mark. Biology definition: the classification system is a system for classifying things, particularly, the collection of procedures, characteristics, and definitions used to classify and or identify things. the levels of biological classification are as follows: species » genus » family » order » class » phylum » kingdom » domain (from least. The highest level, domain, is a relatively new addition to the system since the 1990s. scientists now recognize three domains of life, the eukarya, the archaea, and the bacteria. the domain eukarya contains organisms that have cells with nuclei. it includes the kingdoms of fungi, plants, animals, and several kingdoms of protists. The eukarya domain includes all four eukaryote kingdoms: plants, animals, protists, and fungi. the three domain system emphasizes the similarities among eukaryotes and the differences among eukaryotes, bacteria, and archaea. by using domains, woese was able to show these relationships without replacing the popular six kingdom system.
