  Domain

  In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is the highest taxonomic rank of organisms, higher than a kingdom. According to the three-domain system of Carl Woese, introduced in 1990, the Tree of Life consists of three domains: Archaea, Bacteria and Eukarya. The...
