Addition: This led to the advancement of the phylogentic tree of life consisting of three domains rather than the previously accepted two.

Suggestions:
 * 1) This article does not explain the controversy that was very prevalent in Woese’s findings which led to a delayed acceptance of his theory on the three domains of life
 * 2) The article does not have a link to Archaebacteria, which is the controversial yet fundamental discovery that is central to his research
 * 3) The article title should be changed to The Woeseian Revolution to more explicitly indicate how the findings revolutionized the prior established dogma of a prokaryotic/eukaryotic dichotomy

I have also posted the text of the article below, enjoy!

The Woeseian Revolution The Woeseian Revolution is a term describing the progression of the phylogenetic Tree of Life from two main divisions, known as the Prokarya and Eukarya, into three domains now classified as Bacteria, Archaea, and Eukaryotes. The discovery of the new domain stemmed from the work of biophysicist Carl Woese in 1997 from a principle of evolutionary biology designated as Woese’s Dogma. It states that the evolution of ribosomal RNA was a necessary precursor to the evolution of modern life forms.[1] Although the three-domain system has been widely accepted, the initial introduction of Woese’s discovery received criticism from the scientific community.

Phylogenetic Implications The basis of phylogenetics was limited by the technology of the time, which led to a greater dependance on phenotypic classification prior to advances that would allow for molecular methods of organization. This was a major reason why the dichotomy of all living things, being either animal or plant in nature, was deemed as an acceptable theory.[2] Without truly understanding the genetic implication of each organismal classification in phylogenies via nucleic acid sequencing of shared molecular material, the phylogenetic tree of life and other such phylogenies would no doubt be incorrect. Woese’s advances in molecular sequencing and phylogenetic organization allowed for a better understanding of the three domains of life - the Bacteria, Archaea, and Eukaryotes. In regards to their varying types of shared rRNA, that of the small subunit rRNA was deemed as the best molecules to sequence in order to distinguish phylogenetic relationships because of its relatively small size, ease of isolation, and universal distribution.[3]

Controversy This reorganization caused for an initial push back, being accepted nearly a decade after its publication [4]. Possible factors that led to the initial criticism of the discovery includes Woese’s oligonucleotide cataloging of which he was one of “only two or three people in the world” to be able to execute this method let alone read the films. Also, Woese’s background was in physics whereas most of the research was being done in the realm of microbiologists [5].
