OverviewAI-generated

Archaea is a taxon within the domain and kingdom ranks, classified as a subclass of microorganism. It was discovered by Carl Woese and George E. Fox, with its authority established by Woese, Kandler & Wheelis in 1990. The taxonomic type for this group is Methanobacterium. It reproduces via binary fission and moves by rolling. The organism is subject to the International Code of Nomenclature of Prokaryotes.

Archaea inhabit marine, brackish, and freshwater environments. They have been present since about 3500 million years ago. The group is recognized as accepted by the World Register of Marine Species. Common names for Archaea include Archaebakterie, عتائق, Arxeya, and Археи. In Japanese, it is referred to as 古細菌ドメイン.

Records indicate 40,662 PubMed entries and 46 iDigBio records from institutions in South Africa, the United States, and Madagascar. The taxon is referenced by 2,318 other encyclopedia articles. It appears on the Wikipedia list of vital articles and has a Commons category.

The existence of archaea in the oceans has been known for a long time. However, they were only discovered in the North Sea in the beginning of the 21st century. Archaea resemble normal bacteria, but are very different internally. They can live under extreme conditions: there are archaea known to live in boiling water! Archaea play an important role in the nitrogen cycle in the North Sea. These organisms are capable of changing ammonia into nitrite. One liter of seawater by Texel contains 5 to 45 million archaea. They are found particularly in the winter, when there is too little light for algae to grow.

Gli archèi o archèobatteri, nome scientifico Archaea (dal greco antico ἀρχαῖα, cioè antico) o Archaeobacteria che significa "batteri antichi", sono una suddivisione sistematica della vita cellulare. Possono considerarsi regno o dominio a seconda degli schemi classificativi, ma mostrano strutture biochimiche tali da considerarsi un ramo basilare, presto distaccatosi dalle altre forme dei viventi. Nonostante il nome attribuito a questo taxon, gli archaea non sono i procarioti più antichi mai apparsi sulla Terra, ma sono stati preceduti dagli eubatteri. Essendo costituiti da singole cellule mancanti di nucleo, per forma e dimensioni molto simili ai batteri, sono stati in passato classificati assieme ad essi, come procarioti o monere. Originariamente furono ritrovati negli ambienti più estremi, ma successivamente sono stati trovati in tutti gli habitat, compreso l'intestino umano, nel caso del Methanobrevibacter smithii. Nonostante non sia del tutto sicura la filogenesi del gruppo, gli archei sono quindi (insieme agli eucarioti e agli eubatteri) uno dei tre fondamentali gruppi degli esseri viventi nella classificazione di Woese. Tesi recenti propongono di considerare Archea ed Eukaryota un unico regno, contrapposto ai Bacteria, in quanto all'origine degli eucarioti vi sarebbe l'endosimbiosi mitocondriale..
