These microbes ( archaea; singular archaeon) are, meaning they have no. Archaea were initially classified as, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is. Archaeal cells have unique properties separating them from the other two domains of life, and. The Archaea are further divided into multiple recognized. Classification is difficult because the majority have not been in the laboratory and have only been detected by analysis of their in samples from their environment. Archaea and bacteria are generally similar in size and shape, although a few archaea have shapes quite unlike that of bacteria, such as the flat and square-shaped cells of. Despite this morphological similarity to bacteria, archaea possess and several that are more closely related to those of eukaryotes, notably the involved in and. Other aspects of archaeal biochemistry are unique, such as their reliance on in their, including. Archaea use more energy sources than eukaryotes: these range from, such as sugars, to, or even. Salt-tolerant archaea (the ) use sunlight as an energy source, and other species of archaea, but unlike plants and, no known species of archaea does both. Archaea by,, or; unlike bacteria and eukaryotes, no known species forms. Archaea were initially viewed as living in harsh environments, such as and, but they have since been found in a broad range of, including soils, oceans, and. They are also part of the, found in the, mouth, and skin. Archaea are particularly numerous in the oceans, and the archaea in may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the and the. No clear examples of archaeal or are known, but they are often. One example is the that inhabit and guts, where their vast numbers aid. Methanogens are also used in production and, and exploits enzymes from extremophile archaea that can endure high temperatures and. Archaea were first found in extreme environments, such as volcanic. Pictured here is of. For much of the 20th century, prokaryotes were regarded as a single group of organisms and classified based on their, and. For example, microbiologists tried to classify microorganisms based on the structures of their, their shapes, and the substances they consume. In 1965, and proposed instead using the sequences of the in different prokaryotes to work out how they are related to each other. This approach is the main method used today. Archaea were first classified as a separate group of prokaryotes in 1977 by and based on the sequences of (rRNA) genes. These two groups were originally named the Archaebacteria and Eubacteria and were termed Urkingdoms by Woese and Fox; other researchers treated them as or subkingdoms. In this publication Woese and Fox presented the very first pieces of evidence for the concept of archaebacteria - which at that time contained only the methanogens - as a separate 'line of descent': 1.
