Description:
The discovery of the Archaea and the proposal of the three-domains 'universal' tree, based on ribosomal RNA and core genes mainly involved in protein translation, catalysed new ideas for cellular evolution and eukaryotic origins. However, accumulating evidence suggests that the three-domains tree may be incorrect: evolutionary trees made using newer methods place eukaryotic core genes within the Archaea, supporting hypotheses in which an archaeon participated in eukaryotic origins by founding the host lineage for the mitochondrial endosymbiont. These results provide support for only two primary domains of life--Archaea and Bacteria--because eukaryotes arose through partnership between them.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Tom A -- Foster, Peter G -- Cox, Cymon J -- Embley, T Martin -- BB/C006143/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2013 Dec 12;504(7479):231-6. doi: 10.1038/nature12779.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Cell and Molecular Biosciences, University of Newcastle, Newcastle upon Tyne NE2 4HH, UK. ; Department of Life Sciences, Natural History Museum, London SW7 5BD, UK. ; Centro de Ciencias do Mar, Universidade do Algarve, Campus de Gambelas, 8005-139 Faro, Portugal.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24336283" target="_blank"〉PubMed〈/a〉
