''Such famous figures as Salvador Luria and Ernst Mayr found the idea that prokaryotes were not all of one kind absurd, and did not restrict their mockery to the scientific level.

This is a badly stereotyped view of Woese's critics. Actually, one of Mayr's criticisms of the three-domain system was that prokaryotes may be of more than two kinds, i.e. that the Eubacteria and criticism of him was restricted to the scientific level.

which leaves a lot to be said, but I think does more justice.

Pronunciation

Can somebody please include how the name Woese is pronounced correctly?

I say Woe-Zee, you say what? (He sends his power tools to my shop for repair, but how to pronounce, I can't really say.)

I took a course from Carl Woese in 1993. The second "e" in his last name is silent.

I have no idea where to put this, but I took a course of his in the spring of 2005. He spent 3 or more classes solely explaining how the word 'prokaryote' should never be used. Seeing this in the article makes me angry given that I am now a teacher and refuse to use the word when I see it in textbooks. — Preceding unsigned comment added by 12.206.0.160 (talk) 02:05, 26 September 2012 (UTC)[reply]

Date inconsistency

Can someone please check the date that Woese identified Archaea? This article says 1976, but Archaea says 1977

Thank, GabrielF 00:40, 31 January 2006 (UTC)[reply]

The relevant paper was published in November 1977 - changing the article to reflect this. Dooky 19:25, 19 February 2006 (UTC)[reply]

But Woese actually discovered the group in 1976 (see his introduction to Archaea: Evolution, Physiology and Molecular Biology by Roger A Garrett) so both dates have some merit JackAidley (talk) 12:43, 20 August 2009 (UTC)[reply]

Not so obvious

The article looks like written 20 years ago. Now, at least in the case of Eukaryotes it is known that the phylogenetic tree presented by Woese is false. The critics of Woese were right. See Eukaryotes (in English or French Wikipedia) for more current phylogenetic classification, and learn about "long branch attraction" artefacts (in Wikipedia, too).

The idea of three domains and the name Archaea was proposed not in 1977, but in 1990, and not by Woese alone (Woese, Kandler and Wheelis,Proc. Natl. Acad. Sci. USA, 87, 4576-4579, June 1990, available in the internet, I don't know how to link it). In 1977 it was recognized that some prokaryotes form a separate branch on rRNA trees, but they were called archaebacteria.

There is no obvious reason why to believe that Archaea (or Archaebacteria) are more ancient than other prokaryotes. Some good biologists (like Cavalier-Smith) show strong evidence they are the latest branch of the bacterial tree, not the earliest.

I change the text just a little.

Misconception =

I deleted the insertion -- it is simply misleading to suggest that current debates about the classification of eukaryotes in any way bring into question the objective existence of the Archaea as a distinct group. It is also certainly incorrect to suggest that the "critics of Woese were right" if the critics in question are the original group of critics such as Luria, who questioned the uniqueness of the Archaea. Certainly, the 1990 rRNA tree wasn't the final word on phylogeny, and some groups (such as the "crown eukaryotes") may prove to be artifacts, but that is more properly addressed in articles on the classification of eukaryotes.

In addition, you seem to be confused by terminology. Certainly the words "Archaea" and "domain" are from 1990, but the *concepts* behind the words was already there in 1977. The early rRNA catalogs did show three groups.

--- Jonathan Badger, The Institute for Genomics Research

Not so obvious

Yes, "defining the Archaea (a new domain or kingdom of life) in 1977" is (at least) misleading. The correct date of defining Archaea as a domain of life is 1990.

I did not say the existence of "Archaea" as a distinct group is being questioned, but their status as a "fundamental domain" is.

This is not quite true that the problems with rRNA trees are limited to eukaryotes. Contrary to the tree, Aquifex seems to be related to proteobacteria and Thermotoga seems to be a gram-positive (e.g. Gupta et. al.). The basalmost position of both seems to be an artefact. If this is true, the tree is false (as it is false in the case of Eukaryotes, why not to say this openly?). And it is doubtful that the position of the two basalmost prokaryotic branches is false and the third (the Archaea) is artefact-free; also the root of the tree was based on speculation. Some people say this, and this is a scientific level of criticism.

And in many other places the text is biased.

One example is "Lateral transfer during this period was responsible for the fast, early evolution of complex biological structures". The sentence is written in such a way that a reader may think this is a biological fact that Woese explained. But "fast, early evolution" is not a fact, but a speculation within the same theory (and unnecessary in other theories).

"This classification subdivides the Eukaryotes into four domains...". Unfair. None of Woese's critics classify Eukaryotes into four DOMAINS. They classify them into four (or 2, or 3, 5...) KINGDOMS. And what is wrong with "four kingdoms" of Eukaryotes?

"old system (...) still remains popular among some scientist." Unfair. The newly proposed classification recommended by the Society of Protistologists (Adl et. al, 2005, see protists) completely ignores the "system" of Woese and his "universal phylogenetic tree". They even suggest using the term "Bacteria" as a valid and recommended synonym of prokaryotes. They are not just "some scientists" - they are the mainstream of science.

"Prior to Woese, Archaea were thought to be extreme organisms...". There were no Archaea prior to Woese. And the first known prokaryotes included by him in Archaea were not extreme organisms, but methanogens from the rumen. This is not an extreme environment.

Let show at least minimal criticisms about Woese's results in Wikipedia.

Response to anonymous critic

The distinction "discovered" vs "defined" is not what you seem to make it out to be. Originally, the article said "discovered", but somebody changed it to "defined" -- I suppose for philosophical reasons arising from the idea, held by some systematists, that higher level taxa cannot be "discovered" but only "defined". But in any rate "archaeabacteria" circa 1977 is exactly the same group as "archaea" circa 1990. It is simply playing silly linguistic games to suggest otherwise.

Secondly, while there certainly exist criticisms to this day of the three domains, they are hardly in the "mainstream of science" -- all major references of prokaryotic systematics such as Bergey's Manual and Barlow's "The Prokaryotes" firmly support the three domains, and Woese received the Crafoord Prize in Bioscience (the Nobel Prize of evolutionary biology, awarded by the King of Sweden on the advice of a board of scientists) for the discovery quite recently in 2003. This doesn't mean that he has to be correct, of course -- but it is pretty clear that at this point in time the mainstream opinion includes the three domains. If and when Bergey's Manual abandons the concept, and people like Gupta win the Crafoord, then it would be reasonable to argue that the mainstream opinion has changed. And arguing that a society of protistologists dislikes the concept of Archaea is pretty irrelevant because prokaryotic systematics is no more their field than is the systematics of fishes.

If anything, the article as written already bows too far in the favor of critics, IMHO.

However, personally, I would agree with your criticism about the line "Prior to Woese, Archaea were thought to be extreme organisms..." -- however, that wasn't a section you changed.

By the way -- why don't you sign your discussions?

-- Jonathan Badger, The Institute for Genomics Research

I was just an accidental visitor who looked for a year when Woese was born and I was surprised by the one-sided (and ironical) way the opinions of His critics were presented.

An example. Woese seems to distinguish domains and kingdoms clearly, isn't it? What about "four Eukaryotic domains" of his critics? Many people use four kingdoms, but who uses four domains? Or, if taxonomy of Eukaryotes is irrelevant to his system, why bother to criticize them here?

Unfortunately, Woese do not limit his tree to Prokaryotes, but includes various eukaryotic lineages as well. The phylogenetic tree is well known, the famous author calls it "universal" or "ultimate", and people publish it in biology textbooks as the last word of taxonomy of life. Let say them somehow that the tree does not necessarily strictly reflects phylogenesis, at least in the case of Eukaryotes (protistologists seem competent there). Otherwise the spread of new ideas will be hindered.

And well, I think it is a pity one should not mention other critical opinions for another many years. You know Bergey's taxonomic outline cannot change radically every 5 or 10 years, and for Crafoord prizes one has to wait even longer.

And I simply did not know how to sign my remarks. Sorry: Witold, 84.10.114.174 10:09, 4 April 2006 (UTC), Poland, a publisher.[reply]

Legend for the image "Phylogenetic Tree of Life"

I have a problem with the legend for the image "Phylogenetic Tree of Life" in that the image itself shows a rooted tree (which is how Woese et al. drew it in PNAS (vol 87 p 4576) but as far as I know (which admittedly is not that much on this topic) modern taxonomist don't root a tree unless there is something to root it with. Should the legend be expanded to say that this is based on Woese's diagram of the tree of life, or say that a root in the tree of life in this diagram is speculative (as previously commented above)? PS sorry about the poor grammar. English is my second language - Bad English being my first. PRH969 00:17, 24 March 2007 (UTC)[reply]

Well, I don't know that it's necessary as the image caption itself says almost nothing, and clicking on it takes you to the image page. Go ahead and say, "speculatively rooted Tree of Life" by Carl Woese, if you like. It sounds awkward and raises questions that aren't at issue in an article about Woese rather than his research. The image is almost always used with the caption, "speculatively rooted tree of life." This tree isn't about modern taxonomy, but about evolutionary taxonomy, so what modern taxonomists do can be different without there being any conflict. The article on phylogenetic trees on Wikipedia has at least the basic information on this. KP Botany 01:54, 24 March 2007 (UTC)[reply]

Oops. My mistake. I clicked on the image but don't remember reading the discription properly. My concern was that someone with no knowledge of the topic would see the tree and think of it as the definitive tree of life. I was going to change the legend to "...tree of life based on Woese et al. rRNA analysis." and then include a link to reference #1 PRH969 03:06, 24 March 2007 (UTC)[reply]

To edit an image, you have to edit the section in which the image is located. First copy some of the text under the image so you can find it--it can be messy finding the image if it is in the main section, and you have to click on "Edit this page." Then click on the "edit this page" tab at the top, or click on the "edit" tab in the section on interest. Use a browser function to search for the text. In this case, I would copy part of the text under the image. When you find the image's html in the edit box, edit it as you would anything else. In this case, I clicked "edit this page," went to the edit box, searched for the string "Phylogenetic tree based on Woese et al" and found this:

[[image:Phylogenetic_tree.svg|left|thumb|250px|Phylogenetic tree based on Woese et al. rRNA analysis <ref name="Woese_1990">{{cite journal | author = Woese C, Kandler O, Wheelis M | title = Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya. | url=http://www.pnas.org/cgi/reprint/87/12/4576 | journal = Proc Natl Acad Sci U S A | volume = 87 | issue = 12 | pages = 4576-9 | year = 1990 | id = PMID 2112744}}</ref>]].

What I want to edit is the part of this text after the 250px, which is the caption. I'll let you try it. KP Botany 20:57, 24 March 2007 (UTC)[reply]

Yep, that was my edit. I changed it from - [[image:Phylogenetic_tree.svg|left|thumb|250px|Phylogenetic tree based on rRNA genes]] to the above text. You were right, "speculatively rooted Tree of Life" sounds weird, and like you said, its explained fully in the description. Hopefully the change implies that this was how Woese drew it at the time and not necessarily how the tree is viewed today. PRH969 03:53, 25 March 2007 (UTC)[reply]

Yeah, I think it's fine like that, especially with the specific link to a source, as the underlying concepts are way beyond the scope of an article on Woese. KP Botany 04:03, 25 March 2007 (UTC)[reply]

Rejection of common descent?

Phillip E. Johnson quoted Woese saying "the time has come for biology to move beyond the doctrine of common descent" (no citation) in the magazine Salvo, issue 4 pg 40. My guess is this is a intelligent design proponent taking him out of context to twist the meaning. If not, tho, it seems to change Woese's whole career. Any insight is appreciated. --Ephilei (talk) 02:16, 7 February 2008 (UTC)[reply]

He meant as he did in "biology's Next Revolution" written for Nature in 2007, that, as Máximo Sandín, and other evolutionist think, that facts such as Horizontal Gene Transfer, Transposons, micro-RNA containing virus, genomic retrovirus presence, complex nets models applied in ecology and a long etc, as well as the evidences on Origin of Life research, suggest that the so-called Darwinian evolution model is obsolete, and should be substituted by a new theory, that could explain Evolution much better than random mutation and competition. There is no evidence absolutely of LUCA, and the term Specie is everyday less explanatory and more and more difficult to define. This hasnt got anything to do with intelligent design or creationism, is another conception of evolution which I, as a biologist, also share.

The tree of life

According to the book by Stryer titled Biochemistry sixth edition page 3 shows that Eukarya branches off frm the Archaea and not as it is shown in the diagram of this article. —Preceding unsigned comment added by 88.217.55.129 (talk) 10:07, 4 June 2008 (UTC)[reply]

That diagram of the Phylogenetic tree needs to be redrawn placing the Bacteria and Eukaryota on one branch, and the Archaea on another. Also the spelling errors in the diagram need correction. Rotational (talk) 07:02, 19 August 2008 (UTC)[reply]

On prokaryotes and Woese

Isn't it kind of strange to use the term prokaryote in an article about Woese since both he and his closely-connected colleagues (like Norman Pace) have explicitly written that Woese did the experiment that disproved its existence? See http://www.ncbi.nlm.nih.gov/pubmed/19258530 for the free article. There is no prokaryote, there is just bacteria and archaea and the archaea are more closely related to the eukaryotes than to bacteria. Prokaryote is a term that holds no evolutionary significance and can only mean, not a eukaryote.— Preceding unsigned comment added by Gene_Godbold (talk • contribs) 19:40, 8 January 2013‎ (UST)

I think the use of the term here makes sense because it is placing it in historical context, that is, how did 'prokaryote' cease to be a term with any phylogenetic meaning? It might be hard to describe how that occurred without using the term. While the sentence ending the lead paragraph of the 1977 article ("They can be viewed as prokaryotes that are not bacteria.") does use it in its organizational sense, the linked article discusses that it has no evolutionary meaning, which should also become clear in the discussion that follows. I think as people work the article over the next few weeks this will become a bit more explicit.— James Estevez (talk) 01:04, 9 January 2013 (UTC)[reply]

Image request pending (31 Dec 2012)

Today, I emailed the Communications director at IGB in hopes that they'll release an official portrait under a suitable license. As I understand it, with CW's passing an exception for a non-free image may be made, but a free image is always preferable. However, while I wait for a response I think it would be OK if an editor adds an interim non-free image. Suggestions welcome. James Estevez (talk) 02:25, 1 January 2013 (UTC)[reply]

Done: Forwarded permission to OTRS and added image to article. James Estevez (talk) 03:02, 4 January 2013 (UTC)[reply]

RNA world hypothesis inconsistency?

This article says Woese "was also the originator of the RNA world hypothesis in 1967", but the link to "RNA world hypothesis" says "Alexander Rich first proposed the concept of the RNA world in 1962". Do not these two articles contradict each other? — Preceding unsigned comment added by 2601:646:C000:2177:841C:BFAB:E289:CBCC (talk) 04:45, 1 October 2018 (UTC)[reply]

Structure of DNA

"Interest among physicists and molecular biologists had begun to coalesce around deciphering the correspondence between the twenty amino acids and the four letter alphabet of nucleic acid bases in the decade following James D. Watson, Francis Crick, and Rosalind Franklin's discovery of the structure of DNA in 1953." I detect an attempt to frame a point of view here. Watson, Crick and Maurice Wilkins were awarded the Nobel Prize (Physiology or Medicine) in 1962 for the structure of DNA. No-one, least of all those three, disputes Franklin's role in the discovery. Had she lived to the early sixties, by which time the structure proposed by Watson and Crick in their 1953 paper was confirmed, it is probable, in my view but shared by others, that the Nobel guys would have given Watson and Crick the Physiology or Medicine award and the Chemistry one to Franklin, Wilkins and (possibly) Gosling who took the famed Photo 51.

I think that the most accurate rendition of this sentence would be EITHER "Interest among physicists and molecular biologists had begun to coalesce around deciphering the correspondence between the twenty amino acids and the four letter alphabet of nucleic acid bases in the decade following James D. Watson and Francis Crick's discovery of the structure of DNA in 1953." OR (and I prefer this) "Interest among physicists and molecular biologists had begun to coalesce around deciphering the correspondence between the twenty amino acids and the four letter alphabet of nucleic acid bases in the decade following discovery of the structure of DNA in 1953 by James D. Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin, and Ray Gosling."

I will give this a week or two for reactions and I may make changes accordingly.Cross Reference (talk) 16:41, 7 August 2020 (UTC)[reply]
