Domain
From Palaeos
A domain (also superregnum, superkingdom, or empire) is the largest and most inclusive grouping of living organisms, higher than a kingdom. There are several modern alternative domain classifications of life Among them are:
- The two-empire system, with top-level groupings of Prokaryota (or Monera) and Eukaryota empires.
- The five-kingdom system with top-level groupings of Protista, Monera, Fungi, Plantae, and Animalia.
- The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Eubacteria, and Eukarya domains.
In Palaeos, we have used the latter these three as the top-level classification of life.
Thus, the three domains are:
However, earlier postulated forms of life may not fit within any one of these domains.
