Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotic life consists of two very different groups of organisms that evolved independently from an ancient common ancestor.rchaea were originally described in extreme environments, but have since been found in all habitats and may contribute up to 20% of total biomass. These cells are particularly common in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet.
