Archaeans

Archaea, also known as Archaeans, are one of the three major groups of organisms that make up the domain of life (along with Bacteria and Eukaryotes). Archaeans are single-celled, prokaryotic organisms that typically live in extreme environments and represent a diverse group of organisms. Archaeans have been found living in extreme temperature, high salinity, and high acidity environments, but are also found in many other types of habitats. Archaeans are important as they play an essential role in the global carbon cycle, in the purification of water and wastewater, and in the production of bioproducts. Archaeans are also important to research, as they are excellent model organisms to study life in extreme environments, and to understand the evolution of the three domains of life.
