Kingdom
The major taxonomic group in the current classification of living organisms with the exception of informal division of prokaryotic and eukaryotic empires. The five Kingdoms are Monera, Protoctista, Fungi, Plants and Animals. In the late 1980s Cavalier-Smith proposed that within the Eukaryota there are six kingdoms: Archezoa, Protozoa, Chromista, Plants, Fungi, and Animals (see also taxonomy).
