Domain the highest level of classification currently recognized by biologists refers to the broad differences between the cells of eukaryotes bacteria and archaebacteria. Before its separation the domain archaea was formerly called the domain archaebacteria which is a misnomer since these organisms were not bacteria but belong to a separate clade. They are characterized by maintaining their own differences against other prokaryotes and against other domains at some point classified as similar. The name archaebacteria was previously an untested hypothesis about the evolutionary status of the organisms having a type of metabolic ability that seems to be highly suited to the primordial conditions.
The domains include eukaryota eubacteria and archaea. The three domain system is a biological classification introduced by carl woese et al. Under the archaea domain there are three main divisions or phyla. Kingdom the level of classification below domain kingdoms separate eukaryotes such as plants and animals into groups based on their phylogenetic relationships.
Archaea ɑːr ˈ k iː ə or ɑːr ˈ k eɪ ə ar kee ə or ar kay ə singular archaeon constitute a domain of single celled organisms these microorganisms lack cell nuclei and are therefore prokaryotes archaea were initially classified as bacteria receiving the name archaebacteria in the archaebacteria kingdom but this classification is obsolete. Many archaea live in extreme environments such as hot springs and deep sea hydrothermal vents and. The key difference from earlier classifications is the splitting of archaea from bacteria.
