In biological taxonomy, a domain (an aa superregnum, superkinrick, empire, or regio) is the heichest taxonomic rank o organisms in the Woese taxonomic seestem (there is sometimes a superkinrick Neomura), heicher than a kingdom. Accordin tae the three-domain seestem o Carl Woese, introduced in 1990, the Tree o Life consists o three domains: Archaea, Bacteria an Eukarya.[1] The arrangement o taxa reflects the fundamental differences in the genomes.
