Archaea — timeline of the third domain

  title={Archaea — timeline of the third domain},
  author={Ricardo Cavicchioli},
  journal={Nature Reviews Microbiology},
The Archaea evolved as one of the three primary lineages several billion years ago, but the first archaea to be discovered were described in the scientific literature about 130 years ago. Moreover, the Archaea were formally proposed as the third domain of life only 20 years ago. Over this very short period of investigative history, the scientific community has learned many remarkable things about the Archaea — their unique cellular components and pathways, their abundance and critical function…

The landmark discovery of Archaea drew much attention to this new form of life and a number of laboratories have since become involved in studying Archaea for clues on the fundamentals and evolution of life or for enzymes or functions with potential applications.
Introductory Chapter: A Brief Overview of Archaeal Applications
The first member of the Archaea was described in 1880 [1–3]. Yet, the recognition and formal description of the domain Archaea, as separated from Bacteria and Eukarya, occurred in 1977 during early
Major players on the microbial stage: why archaea are important.
Evidence is outlined by an increasingly large and productive group of scientists that demonstrates not only that the Archaea contribute significantly to global nutrient cycling, but also that they compete successfully in 'mainstream' environments.
Extending the conserved phylogenetic core of archaea disentangles the evolution of the third domain of life.
A number of important relationships are resolved, such as those among methanogens Class I, and the definition of two new superclasses within the Euryarchaeota: Methanomada and Diaforarchaea are proposed.
Evolution of the archaeal and mammalian information processing systems: towards an archaeal model for human disease
Archaea could serve as a parsimonious and tractable host for studying human diseases that arise in the information processing systems, and evolution of complexity is likely an central feature of the eukaryotic information processing system.

An overview of methods for genetic manipulation of Methanosarcina spp.
Proteomic Properties Reveal Phyloecological Clusters of Archaea
A novel way to describe the variety of environmental adaptations of Archaea is proposed, termed phyloecological clustering, which could give additional insights into relationships among archaeal species that may be hidden by sole phylogenetic analysis.
Cell Cycle in Archaea : Different Strokes for Different Folks
Recent developments in archaeal genome maintenance are described, including investigations of novel genome segregation machines that point to unforeseen bacterial and eukaryotic connections.


The origin of eukaryotes and their relationship with the Archaea: are we at a phylogenomic impasse?
The origin of eukaryotes and their evolutionary relationship with the Archaea is a major biological question and the subject of intense debate, with several recent large-scale phylogenomic studies divided in supporting either one or the other scenario, despite analysing largely overlapping data sets of universal genes.
Archaeal genetics — the third way
For decades, archaea were misclassified as bacteria because of their prokaryotic morphology, but genome analyses have confirmed that archaea share many features with eukaryotes, particularly in information processing, and therefore can serve as streamlined models for understanding eukARYotic biology.
The Third Domain: The Untold Story of Archaea and the Future of Biotechnology
The Third Domain is the untold story of how the discovery of a new form of life -- first ridiculed, then ignored for the past thirty years by mainstream scientists -- is revolutionizing science,
The Archaea: an Invitation to Evolution†
The objective in establishing the phylogenetic program was not to refine bacterial taxonomy per se, but to restore an evolutionary perspective/spirit to biology, this time the focus would be on the evolution of the cell itself, in particular, the development of its translation mechanism.
Archaea and the prokaryote-to-eukaryote transition.
This review considers the cumulative knowledge about the Archaea in relationship to the Bacteria and Eucarya and the recent use of molecular phylogenetic approaches to reconstructing the tree of life.
Genomic studies of uncultivated archaea
Genetic studies of uncultivated archaea are reviewed within a framework of the phylogenetic diversity and ecological distribution of this domain to reveal considerable heterogeneity among archaeal strains.
A molecular view of microbial diversity and the biosphere.
Over three decades of molecular-phylogenetic studies, researchers have compiled an increasingly robust map of evolutionary diversification showing that the main diversity of life is microbial,
Viruses of the Archaea: a unifying view
A unifying view on archaeal viruses is provided, and they are presented as a particular assemblage that is fundamentally different in morphotype and genome from the DNA viruses of the other two domains of life, the Bacteria and Eukarya.
Mesophilic crenarchaeota: proposal for a third archaeal phylum, the Thaumarchaeota
It is shown that these mesophilic archaea are different from hyperthermophilic Crenarchaeota and branch deeper than was previously assumed, and should be considered as a third archaeal phylum, which the authors propose to name Thaum archaeota.
Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms.
