  2. Woese's dogma - Wikipedia

    en.wikipedia.org/wiki/Woese's_dogma

    Woese's dogma is a principle of evolutionary biology first put forth by biophysicist Carl Woese in 1977. It states that the evolution of ribosomal RNA was a necessary precursor to the evolution of modern life forms. [ 1 ]

  3. Woeseian revolution - Wikipedia

    en.wikipedia.org/wiki/Woeseian_revolution

    The discovery of the new domain stemmed from the work of biophysicist Carl Woese in 1977 from a principle of evolutionary biology designated as Woese's dogma. It states that the evolution of ribosomal RNA (rRNA) was a necessary precursor to the evolution of modern life forms. [1]

  4. Carl Woese - Wikipedia

    en.wikipedia.org/wiki/Carl_Woese

    Carl Richard Woese (/ w oʊ z / WOHZ; [3] 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.

  5. Three-domain system - Wikipedia

    en.wikipedia.org/wiki/Three-domain_system

    A phylogenetic tree based on rRNA data, emphasizing the separation of bacteria, archaea, and eukarya as proposed by Carl Woese et al. in 1990, [1] with the hypothetical last universal common ancestor The three-domain system is a taxonomic classification system that groups all cellular life into three domains , namely Archaea , Bacteria and ...

  6. History of molecular evolution - Wikipedia

    en.wikipedia.org/wiki/History_of_molecular_evolution

    Though controversial at first (and challenged again in the late 1990s), Woese's work became the basis of the modern three-domain system of Archaea, Bacteria, and Eukarya (replacing the five-domain system that had emerged in the 1960s). [31] Work on microbial phylogeny also brought molecular evolution closer to cell biology and origin of life ...

  7. RNA world - Wikipedia

    en.wikipedia.org/wiki/RNA_world

    A comparison of RNA (left) with DNA (right), showing the helices and nucleobases each employsThe RNA world is a hypothetical stage in the evolutionary history of life on Earth in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. [1]

  8. Branching order of bacterial phyla (Woese, 1987) - Wikipedia

    Atomic structure of the 30S ribosomal Subunit from Thermus thermophilus of which 16S makes up a part. Proteins are shown in blue and the single RNA strand in tan. [5]In 1987, Carl Woese, regarded as the forerunner of the molecular phylogeny revolution, divided Eubacteria into 11 divisions based on 16S ribosomal RNA (SSU) sequences, listed below.

  9. Last universal common ancestor - Wikipedia

    en.wikipedia.org/wiki/Last_universal_common_ancestor

    Morphologically, it would likely not have stood out within a mixed population of small modern-day bacteria. The originator of the three-domain system, Carl Woese, stated that in its genetic machinery, the LUCA would have been a "simpler, more rudimentary entity than the individual ancestors that spawned the three [domains] (and their descendants)".
