Carl Richard Woese (/ ˈ w oʊ z /; July 15, 1928 – December 30, 2012) was an American microbiologist and biophysicist.Woese is famous for defining the Archaea (a new domain of life) in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA, a technique that has revolutionized microbiology. He also originated the RNA world hypothesis in 1967, although not …

First proposed in 1977, Carl Woese's three-domain system was not generally accepted until later. One main characteristic of the three-domain method is the separation of Archaea and Bacteria , previously grouped into the single kingdom Bacteria (a kingdom also sometimes called Monera ), [59] with the Eukaryota for all organisms whose cells ...

Le règne (du latin « regnum », au pluriel « regna ») est, dans la taxonomie de Carl von Linné (qui classe la biodiversité en fonction des caractères communs partagés), le plus haut niveau de classification des êtres vivants.Dans les classifications les plus récentes, le règne n'est plus que le deuxième niveau de classification, après le domaine [1], [2] ou l'empire [3].

Glenn Theodore Seaborg (/ ˈ s iː b ɔːr ɡ /; April 19, 1912 – February 25, 1999) was an American chemist whose involvement in the synthesis, discovery and investigation of ten transuranium elements earned him a share of the 1951 Nobel Prize in Chemistry. His work in this area also led to his development of the actinide concept and the arrangement of the actinide series in the …

Terminology. The term domain was proposed by Carl Woese, Otto Kandler, and Mark Wheelis (1990) in a three-domain system.This term represents a synonym for the category of dominion (Lat. dominium), introduced by Moore in 1974. Development of the Domain System. Carolus Linnaeus made the classification of domain popular in the famous taxonomy system he created …

Carl Woese descubrió en los años 1970 que los procariontes encajaban en dos esquemas muy diferentes cuando se examinaba su estructura, composición y genética molecular, distinguiendo dos taxones, Archaea (llamado primero Archaebacteria) y Bacteria (llamado a veces Eubacteria), con la categoría nueva de dominio.
