1990 C. R. Woese et al. in Proc. National Acad. Sci. U.S.A. 87 4576 We propose that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a ‘domain’. Life on this planet would then be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms.
