==Suggested strategy for further revision==
==Approval==
OK, I've updated the version number, and don't see any dissent from approval, so at the end of today, this article will be approved unless there is a last minute objection.[[User:Gareth Leng|Gareth Leng]] 06:05, 10 March 2008 (CDT)


Concentrate first on obvious errors and typographical inconsistencies in the first instance so that Version 1.1 folds all these in, and is uncontroversial. Consider primarily only absolutely clear cut improvements . Experience with other articles shows that these glitches are there. I can see one in Ref 1. '''Note.'''.  
:Thank you, Gareth. In the new version number, I still see a typo or two, and a few wikilinks needed, but I will not edit the current version, so you will not have to update the version number again today.  I understand an editor can make minor copyedits to an approved version, but I'll check policy on that if I decide such edits necessary after today's (hopefully) approval.  The curse of the perfectionist.  --[[User:Anthony.Sebastian|Anthony.Sebastian]] 14:20, 10 March 2008 (CDT)

::Anthony, if you want to go ahead and make the changes that you see I will incorporate them into the re-approved version tonight as long as they are not 'content' edits.  Spelling and linking are definitely allowed. I'll just make a note of them on the Approval page.  --[[User:D. Matt Innis|D. Matt Innis]] 15:09, 10 March 2008 (CDT)


:What a task-master you are, David.
:::Thanks, Matt. I made five history-page-recorded edit series since 21:00, after Gareth updated the version number for approval; all corrections of typos or additions of wikilinks.  I appreciate your offer to "incorporate them into the re-approved version tonight", but if that means your inserting the edits yourself manually, that seems too much.  I'm happy to edit the re-approved version after its up, tomorrow say, assuming I have authorization to do such a thing, and assuming an approved version once up is editable by an editor.  If so, you can monitor my edits afterwards.  Save you the work.  --[[User:Anthony.Sebastian|Anthony.Sebastian]] 16:35, 10 March 2008 (CDT)

Well done on the approval.  The article is amazing.
==APPROVED Version 1.2==


I would like to comment on just one small thing I saw.  A sentence reads, "Self-organized systems ultimately are products of a 'blind watchmaker'."  This unnecessarily takes a specific philosophical/religious position. If you're going to say this, you should mention the other position; that's what our [[CZ:Neutrality Policy|Neutrality Policy]] requires. The other way to satisfy the policy, I think, is to say something like, "That biological systems are self-organizing in this way has led one prominent biologist to say they are products of a 'blind watchmaker'."
It appears that we have 3 to 4 approving editors with no significant outstanding issues that were not handled.  This approval can move forward.
<div class="usermessage plainlinks">Discussion for [http://en.citizendium.org/wiki?title=Life/Draft&oldid=100284752 Version 1.2] stopped here. Please continue further discussion under this break. </div>

::Larry, this is a bit out of my bailiwick, but my understanding is that the 'blind watchmaker' model'' is a *way* of describing something which is quite widely accepted, not a viewpoint with valid alternatives within its discipline to which the neutrality policy would necessarily apply.  There are indeed other ways of describing this phenomenon, but not really any body of science which disputes the underlying mechanism itself.  So I'd suggest "That biological systems are self-organizing in this'' way has been aptly described by [[Richard Dawkins]] using the metaphor of a 'blind watchmaker'."  Objections to the model which emanate from various religious or philosophical views could be referenced, but really do not have a bearing on the underlying science itself. [[User:Russell Potter|Russell Potter]]
== looks beautiful.  ==


:Well, it's somewhat in my bailiwick, as it happens; I've taught philosophy of religion, and "the watchmaker" refers to an analogy used to illustrate the teleological argument for the existence of God.  Dawkins is a famous atheist.  The implication is that we are endorsing Dawkins' rejection of the teleological argument.  I'm not saying that anyone ''meant'' that, I'm just saying that that is how the article reads, to this philosopher, at present. --[[User:Larry Sanger|Larry Sanger]] 22:01, 10 April 2007 (CDT)
wow.  I really enjoy the layout. [[User:Tom Kelly|Tom Kelly]] 00:37, 11 March 2008 (CDT)


::I see your point.  I have always quite admired Dawkins's book, and the "blind" in his "blind watchmaker" is a carefully chosen adjective -- implying, I think, not a total rejection of the teleological argument, but the qualified claim that increasing biological complexity does not require -- and yet does not exclude -- an element of intelligence in its design.  If [[Life]] is primarily an article within philosophy or religion, then it certainly should not endorse Dawkins's or any other view (and within both fields there are many others), but if it is primarily a scientific article, it seems to me that one *could* use this metaphor (with citation) to describe the tendency toward complexity of living systems without raising any neutrality issue.  But the article is quite strong; this is a relatively minor point.

:: Re Blind watchmaker metaphor. I'd argue that we don't ascribe to all Richard D's opinions just because we use the same metaphor for a well accepted biological interpretation. Its very apt too for self-organised systems. If they were organised by some entity outside the system, "blind" would not be appropriate, but that possibility's  not part of the topic "self-organised". Also since its an article about biologist's interpretation of life the metaphor is apt.

== Tiny typo ==
==Dawkins rears his ugly head (well metaphoricaly) -he's really good looking women tell me==
The question at issue is not what our opinions about what we are endorsing are, but ''how we can be reasonably interpreted'' by the well-informed reader.  And, as I said, the current wording ("Self-organized systems ultimately are products of a 'blind watchmaker'.[30]") can be thus reasonably interpreted as rejecting a role for God, particularly since it simply ''asserts'' that self-organizing systems are the products of a "God who is not there," citing a well-known atheist. --[[User:Larry Sanger|Larry Sanger]] 08:24, 11 April 2007 (CDT)


I agree with that reasoning- but that's not the reason I'd be happy to see the phrase go. I just didn't understand it in context. A blind watchmaker makes perfectly fine watches using his or her other senses- you don't ''need'' to see to perceive a classic mechanical watch's reading-you can feel the position of the hands - and ,especially if you are a watchmaker-it's a trivial deal to snap off the covering lens, blind or not.  The sound of the gears and the feel of the parts also are enough to make the watch, given sufficient expertise. So it just didn't make sense to me. It seemed to refer to something that I didn't know about, and whether or not the writer of the words in the article intended it that way- I guess it did. Taking it as it is- without outside references, for it to make sense you have to actually know very little about either making watches or what blind people are routinely capable of, and then I guess you might assume a blind person couldn't possible make or read a watch any more than a monkey. False, to put it mildly. [[User:Nancy Sculerati|Nancy Sculerati]] 08:54, 11 April 2007 (CDT)
This paragraph in the Molecules paragraph contains a weird fragment: "For the possibility of extraterrestrial life based on inorganic matter see novel proposal of physicists Tsytovich et al. A mass of charged particles — like a swarm of bees — exhibiting features similar to Earth-type living systems". Is this the right way to bring attention to this? [[User:Joshua Choi|Joshua Choi]] 03:02, 29 March 2009 (UTC)


::Sounds as though Dawkins's book is not as well-known as it once was -- probably another good reason not to allude to it in this particular article, as it may well create a point of puzzlement rather than enrichment.  It is also, I must admit; somewhat dated in this respect; looked at from today's point of view, "blind" is probably an unfortunate choice of adjective; Dawkins doesn't mean literally "deprived of one sense" but rather "directionless, not volitional."  The best solution here might be to create an entry on Dawkins and/or his book; once CZ users can click on a direct link, the allusion would function properly, which it clearly does not at present.  Still, I think it is much too facile to dismiss Dawkins's notion as false on this account.  I might mention at this moment that Dawkins is currently the Charles Simonyi Chair for the Public Understanding of Science at Oxford University.

== Approved? ==


Well, if what is meant by "blind" is operating randomly, then it does make a lot of sense - as a concept. But the user of this CZ article LIfe will only read the word "blind" that way if he or she is fully familiar with Dawkins and his use of the word. That is part of my previous objection to making this into the "great man" (a la Galen) worship- fine to have an article on Dawkins, fine to link it, fine to actually quote scientists and philosophers, but that's the limit. Not fine to imply that instead of thinking for ourselves we will survey the great thoughts of the great men and marvel at their great wisdom.

::Dawkins may or may not be a 'great man' -- I agree that we should not fall down at the feet of ostensibly ''great'' thinkers and just cite their thoughts as though they were self-evidently brilliant -- but I do think his views on life and evolutionary biology are significant enough, just judging from the enormous impact they had at the time within the field, that within a reasonable notion of neutrality in articles, they can and should be "noted", though not necessarily here at this point in this entry.
It is from the section titled "Evolutionary aspects of 'living'". [[User:David Finn|David Finn]] 11:20, 8 November 2010 (UTC)


::Given that CZ places a great value on expertise ''qua'' expertise, certainly Dawkins is an expert, even though (and because) some other experts may disagree with him.  At the same time, he is also known as a very activist sort of atheist, a fierce critic of religion in general, and for this reason his name alone raises hackles in some quarters, even though his theories about biology can (and I think should) be considered entirely apart from his other views.  [[User:Russell Potter|Russell Potter]] 09:23, 11 April 2007 (CDT)
Thanks, fixed[[User:Gareth Leng|Gareth Leng]] 12:24, 8 November 2010 (UTC)


Russell, be that as it may-and I've taken the liberty of translating the wikipedism in your post into "neutrality in articles", this page is about the article Life, and how it can be improved- and my objection to the "blind watchmaker" is that it does not make sense unless it is placed in the context of an individual's contribution to the field, and a survey of the individuals - rather than strictly the ideas, is problematic. For example, the ideas of Aristotle are applied to living systems in a way that makes sense, and is-of course-linked to a great referemce. The idea of the "blind watchmaker" as presented in the article makes no sense- unless the reader has the background to know that the word blind is being used strictly as its fourth (or fifth or sixth)  meaning instead of its first. Maybe I am wrong about it refering to Dawkins, per se, and so maybe the idea of the "great men" is misplaced, but even if it is a phrase in some form of traditional philosophy- it does not stand by itself as clear without a full explanation of what is meant by "blind", except to those who are ignorant of the high end of abilities of the visually blind.  We are after truth here and not the appearance of political correctness. I like to think that truth is eternal. Of course, I liked to think that about love,too. And so, I may well be wrong. Regardless, I stand ''my'' ground against changing text on the vague and shifting grounds of ''the possibility'' of raising hackles, through popular (or as you say-even relatively obscure) associations that might upset some political or religious or scientific subgroup. Those kind of things might be life, as Anthony is fond of punning (God help us all), but it is ''not'' [[Life]]. This article must be as true as we can make it. That's all.[[User:Nancy Sculerati|Nancy Sculerati]] 09:39, 11 April 2007 (CDT)

Don't see the problem: blind watchmaker is in quotes that should display the fact that it's not intended literally, and the adjacent footnote gives the full explanation. It's also true I think that ''any'' purported mechanistic explanation of life may raise hackles; it goes with the turf.[[User:Gareth Leng|Gareth Leng]] 11:23, 11 April 2007 (CDT)

::Sebastian butting in:  Though I agree completely with Gareth, I say we give Larry's concerns the benefit of the doubt re misinterpretation and neutrality, and change to the wording he suggests.  It does not detract from the point. And, Nancy, since people commonly use phrases such as "blind fate", "blind faith", "blind date" and "blind alley", readers should not be blind to the metaphorical uses of "blind". Nevertheless, since I introduced the term, I will look again carefully in response to your concerns and the comments of others. --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 17:09, 11 April 2007 (CDT)
:Great find, Sandy. I found the 20 comments on the Trifonov article even more interesting.


: Larry's useful comment has to be put through scholastic tests of relevance, scientifically tested validity, style, and conciseness. They are in my opinion, worth rejecting on all four grounds. The interpretation Larry alludes to of the "blind watchmaker" phrase is not necessary, nor taken or implied  in the [[Life]] passage, the non-scientific interpretations raised by his argument are irrelevant to the passage in question, carry no authoritative or accepted argument or scholarship about biology, and will mar the style and clarity of the passage. But wait. There's more. Nancy arguing his (Dawkin's) metaphor will be misunderstood by many. Hmmm. That's something we cannot dismiss.
:What thoughts do you have re 'defining life'?


The Blind watchmaker words are only justified because they were efficient at communicating the concept of how self-organisation was generated, who said it first (great woman or flawed man, atheist or Lutheran) is irrelevant other than to provide a checkable source. Maybe I am fooled because I've read his books and enjoy them despite some irritating abrasiveness (except the God Delusion which is, IMHO a waste of energy).

If Nancy is right that the metaphor is not accurate or clear , then let's find a better one. It's quite a challenge in two words. A Rose by any other name would smell as sweet.
:I keep thinking: Because living systems hasten the pace to maximizing the entropy of the universe, whenever/wherever energy-matter conditions permit, living systems perforce will emerge.  Systems that generate more disorder in the system plus surroundings than the order they generate in themselves.  The universe longs for its 'heat death'.

I thoroughly agree with Nancy's "Great man" argument, and would indeed live happily live with the elimination of eminent names. I have been uneasy about them: Schroedinger, Mayr, Dawkins, Kaufmann. Darwin we can hardly avoid, but hero worship has no place in neutral statements.

:David:  Your points, well-taken.  I had already edited the paragraph as follows.  It doesn’t seem to damage the message, especially given the unchanged footnote, which also follows:
== Disambiguation, or whatever ==


<blockquote>The patterns of structure and behavior in self-organized systems need no behind-the-scene 'master controller', and no prepared recipes that specify the structure and dynamics of the system. Instead, those patterns emerge from the interactions among the naturally selected components of a system, dictated by their physical properties, and dynamically modified by the emerging organization, which is itself modified by the environment. Thus the single-celled zygote self-organizes into a multicellular living system as the genetically encoded proteins interact, responding to changing influences from the changing environment generated by growing multicellularity — becoming a network of many cell-types working cooperatively. That biological systems self-organize in that way has led one prominent biologist to say they are products of a 'blind watchmaker'. [31]</blockquote>

ISBN 0393304485 Excerpt from Amazon.com review: “The title of this 1986 work, Dawkins's second book, refers to the Rev. William Paley's 1802 work, Natural Theology, which argued that, just as finding a watch would lead you to conclude that a watchmaker must exist, the complexity of living organisms proves that a Creator exists. Not so, says Dawkins: "the only watchmaker in nature is the blind forces of physics, albeit deployed in a very special way... it is the blind watchmaker." Physics, of course, includes non-equilibrium thermodynamics.</blockquote>

Anthony, I'm not making it because I'm worried we are not worshiping women ;) - it's that the ideas should be emphasized and well enough explained that they stand alone, optimally, anyway. Of course, references and quotations are important, but I'm claiming that -in our articles- it's better (optimal) to present the attributed explanations and thoughts as "X exists because Y splits Z", not and" The Great Man (or Great Woman-either way) "attributed X to the influence of Y and Z". In the one case, if the explanation is clear, the argument really explains and stands alone. In the other case, the reader (user) either has to already know the argument to really understand the explanation, or take it as a given that if so and so said it, then its true and no further explanation is really needed. I think this blind watchmaker reference is the only example of this in the text. Personally, I would like to see it (that metaphor) either (1) concisely expanded so that the argument is made clear even to somebody who does not already know it or (2) dropped. Even with the examples you give, blind date etc, "randomly operating" is not so clear. But it's not a life or death edit for the article -;)- just a comment.

== Wondering about accuracy of statement re Silicon ==
 
Can someone allay my concerns about the following in the approved article:
 
"Silicon, carbon's close relative on the periodic table, also forms bonds with itself, but they readily disassociate at the temperatures that are compatible with life as we know it. That is not true at much higher temperatures, and so it is possible to imagine biochemical reactions, more or less as we know them, occurring at, say, 400 degrees Celsius with silicon taking the place of carbon. If they do, one would expect that they too could form structures of such variation in size, shape, charge and composition that might be used to contain and organise information."
 
As I understand it, the Si-Si bond energy has a much lower value than the C-C bond energy, which suggests that at higher than earth life temperatures Si-Si bonds would have little stability, or not form at all.  In that case, stable Si-Si bonds require low temperatures, not the high temperatures of 400 degrees Celsius.
 
I may have my chemistry wrong, and stand ready for correction.  I do not know if silicon people will feel hot or cold to our touch.  --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 16:26, 11 April 2007 (CDT)

Chris, I know this from Physical Chemistry-or think I do (it's been a few years- but its basic stuff).

==Another Scientific concern about Life Version 1.  LUCA is DEAD==
 
In [[Life]] we say
"All living things extant today descended with modification from a single common ancestor, a unicellular organism."
 
This statement is grossly misleading and about 5 years out of date. The Last Universal Common Ancestor (LUCA) concept is long dead in the water. To retain scientific credibility we need to change it.
 
Note below links to just a few of the numerous relevant current papers (which I am attentively reading in preparation for an assault on [[Evolution of cells]], as a prelude to a thrust at the [[Origin of life]]). They and others document my seemingly bald assertion:
 
* [http://en.citizendium.org/wiki/Evolution_of_cells#Community_metabolism Community metabolism]
 
* [http://www.pnas.org/cgi/content/full/99/13/8742 The Root of the Universal Tree.]
 
<blockquote>
The universal tree has no root in the classical sense (1, 21). The root is actually a Darwinian Threshold, the first point at which we can begin to give tree representation to the organismal evolutionary course. A certain "symmetry of descent" is inherent in the classical view that is totally lacking here. In a classical phylogenetic bifurcation both sister lineages and their common ancestor are in essence alike. But, at the root of the universal tree (and in the first branching of the tree) classical presumptions do not hold (21), because the root is not a classical root, the sister lineages resulting from the earliest branchings are in no sense "sisters." They differ in fundamental ways.
 
The nonclassical perspective required here takes some getting used to. We need to release all of the classical connotations of "symmetry" in these "bifurcations." That the cell type on one side of the initial bifurcation has crossed a Darwinian Threshold does not imply that the organisms represented by the other side have done so. Indeed, different cell types would be expected to reach their Darwinian Thresholds more or less independently, at different times (1). The initial bifurcation of the universal tree (Fig. 1) tells us only that the bacterial cell type has crossed its Darwinian Threshold (23). Although the archaea and eukarya are represented by a "common lineage" at that stage, this is deceptive: the two are in effect lumped by forcing tree representation on the situation. Neither has yet to establish a stable genealogical trace. Neither has crossed its Darwinian Threshold. And that is all that their so-called "common ancestral lineage" signifies.</blockquote>

The difference between this error and Si chemistry is that the Si statement  was clearly labeled as fantasy scenario, whereas we present our common ancestor sentence as a considered scientific statement.

:I'm sorry, I don't understand.  I can't figure out what that quoted paragraph is trying to say.  Are you saying that two or more currently extant kinds of life emerged without any common ancestor (i.e. evolved from scratch separately)?  Or are you saying that reproduction looked different back then, so that although the two or more kinds of life were related in some sense, they were not related in the way we usually think of things being related, i.e. cell division?  There's the idea of organelles having been originally separate life forms;  does that have anything to do with what you're trying to say?
 
::: It not me thats saying that paragraph, its Carl Woese, from this paper: [http://www.pnas.org/cgi/content/full/99/13/8742 The Root of the Universal Tree.]
 
:::He's not talking about two kinds of life but three kinds of life. He's also saying that reproduction was diffeent then, some 3 billions years ago. Yes the organelle symbiosis idea does have something to do with it and the details are discussed in the papers. [[User:David Tribe|David Tribe]] 07:43, 16 April 2007 (CDT)

::: I'd argue the mitochondrial event is later than the very early events the Woese quote refers to are taking about-they are the times that the three "canonical' forms emerged and thay preceded the mitochondrial symbiosis most likely.

:I believe that the sentence is neither misleading nor out of date, but I'm open to arguments otherwise.  Following one of the links you gave, I get the impression that what you mean is not that life evolved from scratch more than once, but that a given life form may have had more than one ancestor;  in other words, that it would not be accurate to think of all life as having evolved from a single unique ancestor in a simple way under plain asexual reproduction without mixing of genes with other organisms.  Nevertheless, the sentence does not appear inaccurate to me.  The word "ancestor" is often used to describe humans, for example, who also had other ancestors.  Perhaps the sentence could be reworded to make more clear the obvious idea that if there was one such common ancestor, there was almost certainly more than one such (e.g. a/the parent of that common ancestor).  How about ''"There were some unicellular organisms in the distant past such that each one of them was an ancestor of all life alive today."''  --[[User:Catherine Woodgold|Catherine Woodgold]] 14:40, 15 April 2007 (CDT)

== Topic sentence of self-organization section ==
 
The first sentence was
*''"Living systems organize themselves spontaneously."''
I've changed it to
*''"The self-organizing activity of life occurs by means of positive and negative feedback loops that occur at many levels, from macroscopic to microscopic, among the material of which life is built."'' 
Many other first sentences for this paragraph are possible, but the one I took out feels to me as if it's just repeating what had been said (or implied several times) earlier in the article;  it doesn't pull me into reading the paragraph.  A good sentence is needed here to get the reader to settle back into their armchair and sink into the text after having had a boxed quote, point form section and a couple of section headings close together; otherwise this is a likely place to lose the reader's interest. 
 
Other possibilities for this sentence might be:
*''How do living systems organize themselves spontaneously?''
*''It seems almost paradoxical how living systems organize themselves spontaneously.''
*''Self-organization emerges from the interactions of material things.''
*''The ability to organize itself sponteneously is a defining characteristic of life.'' (This one may also be too much a mere repeat of what has already been said.) --[[User:Catherine Woodgold|Catherine Woodgold]] 14:19, 15 April 2007 (CDT)

:::Sorry, maybe it would have worked better if I'd discussed it on the talk page first before editing, especially now that there's an attempt to get a stable version approved.  Anyway, the way it now stands looks good to me:  David Tribe has changed it to ''"Self-organization emerges from the interaction of life's components."'', which is one of my suggestions but changed somewhat.  I may be busy for the next while, so if people want to change this first sentence back to the original (for the current version or more permanently) or change it in some other way, please feel free.  The original sentence may look better to me if the number of occurrences of the word "organize" is reduced in the part of the article that comes before this sentence; I may make some more specific suggestions later on about how to do this as well as further discussing why. By the way, the way it now stands perhaps "self-organization" could be replaced by "it" in the second sentence.  --[[User:Catherine Woodgold|Catherine Woodgold]] 07:37, 17 April 2007 (CDT)

The fact is that Nancy and myself, Chris Day , Anthony and Gareth have together had about 95% of the approval process experience of the entire wiki, and its obvious to at least Nancy and myself that the proof idea or something similar that works NOW needs to be explained and developed so it does work , until an army of enthusiastic copy-editors arrive on the scene.[[User:David Tribe|David Tribe]] 18:00, 18 April 2007 (CDT)
 
== The word "organize" ==
 
The string "organiz" appears 75 times in the text of the article.  I think it would be good to reduce the number of occurrences to give the article less of a repetitive feel.  Words or concepts which might be substituted include:
*feedback loops
*replication
*phenotypes and genotypes
*learning; experience; testing
*reacting to stimuli
*information
*damage and repair
*resource
*combination, coalescence, union, amalgamation, assimilation, mosaic, collage, joined, congregated
*intertwine, interweave
*orchestrate, self-orchestrate (already appears but only once); self-sufficiency, self-governing
*evolve (This word only appears 4 times in the article at the moment, could be increased)
*homeostasis, regulation; adjust, regulate, coordinate, stabilize, moderate
*order and disorder; orderly; harmony, balance;
*entropy
*attractors (as in chaos theory)
*synthesis, synthesize, assemble
*cascade of cause and effect
*control, e.g. maintaining a steady body temperature or a steady concentration of a substance
*antioxidants
*arrange, regularize, arrangement, disposition
*marshalling, design, plan, contrive, programme
*management, direction
*systematization, codification, synchronization
*formulation, pattern, scheme, method
*structure, form, frame, shape, array
*standardize, make uniform
*disentangle
*whole, holistic; unifying, uniting; integrating
*incorporation, embodiment, comprehend, combination
*mould, shape, rebuild
*interaction
*not "system", though:  it appears about 140 times already!  It doesn't strike me as feeling as annoyingly repetitive as "organize", though, maybe because it's a shorter word, or it just carries less weight semantically. "Information" appears about 50 times; again, maybe OK but no use increasing it.  "Emerge" appears about 15 times.  I'm not saying the word "organize" or "self-organize" shouldn't appear a lot of times in this article -- I'm just saying maybe not *quite* that many;  maybe we could cut it down from 75 to 60 or something, and I think the article would sound better.

:Catherine: I looked through the article and felt that in most cases no other word than 'organized', 'organization' etc. helped in any way in any particular instance.  'Organization' is the special form of 'order' that living things achieve in virtue of their location along a free energy gradient, given their prebiotic evolutionary history and their inherited naturally selected information base.  Sometimes 'dynamic coordination' works.

::There's a long list of words from Catherine that cover related concepts, but what we need is the arguments for each particular situation where the substitute is more apt, accurate, communicative and better, and part of the intended theme or thesis. That's going to take time. For instance, I'm not sure for example where antioxidants fit, and why. I personally don't have much empathy with the word system, but I'd have to argue through my general feeling on particular phrases in context. We don't just have semantics and style to worry about, we have logical structure and narrative, and Catherine is not giving us much to chew on there. On the other hand I personally think both control loops , homeostasis and evolutionary selection are not fully developed, but I don't want to go through another big phase on making the article worse in order to make it better. Being told that to make an omelette's you have to break eggs doesn't get me all excited after this long passage so far.

What'' is'' the big picture, really? I think it has to do with the need for a formal convention of a copyediting stage after approval - a proof. This was discussed in forums [http://forum.citizendium.org/index.php/topic,328.0.html] after the Biology article was first approved. It was accepted then that an editor could take over to copyedit an article - with that final version agreed on by the other editors involved in orginal approval, rather than leave the endpoint of the article a moving target, in which both copyedits of the approved version, and changes in content like new wordings and concepts were all being added simultanously on the wiki. For anyone who has published, the notion of "a proof"- and what is and is not allowable for changes in a proof, is understood. That's what we need here- not a new approved version, simply a proofed copy of the approved version. I think this article offers a good opportunity for us to settle on such a process of "proofing" an approved article. The very first approved Biology version was proofed, but the next approved version lost that stage. And, as David says, it was a difficult process to manage. [[User:Nancy Sculerati|Nancy Sculerati]] 08:28, 16 April 2007 (CDT)
 
:Nancy: I do not view the approved version of [[Life]] as requiring only 'copy-editing', though one can interpret that activity somewhat broadly.  I would like to continue to work on the content of the article, as we receive feedback, and personally as I continue to learn more, from reading and discussion and reflection, about what goes into the process of living. And how best to communicate it. I might choose to invest much of my energy into further development of the article, risking the charge of not dong as much to further CZ in other areas. I doubt I will obsess to that degree, as I have a long list of subjects in Biology and other workgroups that I want to contribute to as best I can.  I see [[Biology]] and [[Life]] as hubs connecting to all articles the Biology Workgroup produces, and for that reason I think we should regard them as unfinished symphonies, not 'proofs'.  In my opinion, of course. --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 19:05, 16 April 2007 (CDT)
 
Of course, Anthony. But that is EXACTLY why we need to have a simple proof- because everyone wants to expand, and although that is a good-even a great thing, we can ''never'' get a proofed stable version unless we approve a version and then allow a proof to be made. Once the proofed approved version is up, the draft continues. When it gets approved, it ''too'' will need proofing, and so on. Do you see? Or is it that extra X chromosome that accounts for my vast superiority in this matter? ;)  I know that can't be- but I have to say something. You know that when you write something it has to be proofed, and you know too that the publisher doessn't want to hear that you have just had a whole new insight and now you have to change it. It doesn't matter that we are publishing in pixels here- we still need to stop and proof. [[User:Nancy Sculerati|Nancy Sculerati]] 21:10, 16 April 2007 (CDT)
 
:Idea/suggestion:  A page can be created called "life/Proof", which anyone can edit but with the understanding that normally only minor changes such as spelling correction are to be made, or possibly reverting some of the last few edits to the Draft pending further discussion.  Meanwhile, more extensive editing can continue on "life/Draft".  On the talk page "life/Proof" people can be encouraged to leave comments like "I read the whole thing and didn't see any errors."  (If true, of course.) --[[User:Catherine Woodgold|Catherine Woodgold]] 07:25, 17 April 2007 (CDT)
 
Catherine, an  Approved Article Version n.x/proof is a '''great''' idea- if its technically possible to do so. I think you have hit on a very practical and concrete solution to the end-game problem we have been experiencing with all approved articles. That would allow ''both'' simultaneous creative work to continue on the Approved Article Version n.x /draft, while the stable versioned article is copyedited (proofed). I will bring this up on the forums (I'll copy your post and attribute it) and on the excecutive committee. We still have not figured out a copyediting process (or style book- but never mind, Rome was not built in a day, or 6 months), and so I think the details of doing the proofing will be a work in progress, but -great idea, I think anyway.

Another ''annoyance'' to me -- a bug that needs fixing before approval -- is this article's quirky combing of British and American style -- or am I mistaken, thus showing my ignorance of British style?  If not, which one will it be?  If American, say so and I will gladly do the honors.  If British, I will have to plead at this time for another to undertake the task. &mdash;&ndash;[[User:Stephen Ewen|Stephen Ewen]] 00:43, 16 April 2007 (CDT)

Stephen, I'm an American and I don't see it as quirky. There is a blend of spellings and styles here, just like there is a blend of ideas- and to me, that is delightful and authentic. Authentic because it accurately reflects the collaborators. Copyediting can easily change nuances of meaning and I would beg any one changing the text who does not have an ''expert'' knowlege of the subject it covers to do so on the talk page and let the editors review it. There will be disagreements even among the "experts" before it is hashed out, most likely. For example, although it may be true that the word "organize" is used more than is elegant in prose for any word to be used in the section Catherine mentions, the "synonyms" Catherine offers are not synonyms to a scientist. The English language does have different styles in different English speaking countries, and since the characteristic of being an international community is a '''cherished''' feature of Citizendium, I feel strongly that we do not want to impose an artificial style of just one or another of these countries. If a South African writes [[Infant colic]], then let it have a South African style. If an American writes another article as primary author, let others either follow suit- or, if the article becomes a real collaboration- as this one did- let the subtle varieties of style remain. A person who is intelligent and educated enough to read this article understands that there are variations, globally, in English- even if the specific conventions and how they differ many not be understood. Gender in the English language (in all its regional forms) is another mish mash that I think is better left without strict convention. The phrase "All mankind" is foolishly forbidden, when it has a grandeur that "all humankind" does not, sometimes saying ''his or her'', or'' her or his'', is good, sometimes just ''his'', sometimes alternating in the text- as is often done when writing about children, using ''his'' in one sentence and ''hers'' in the next, is good.  Citizendium is not English or American (or Australian, or South African or Canadian or Singaporean or Nigerian...) and its language should not falsely make it appear to be one or the other or the next. English language styles over the next centuries, should the human world remain in rapid communication, will likely sort out the conventions into a new hybrid style. Let it be.

An example, Gareth? Sure, first paragraph, intro. We have 'life', "life on earth", "what is life?", 'life', 'living' and “Life is what is common to all living beings”. And so forth. We also have quotations that cannot decide whether the period goes before or after the ", hence, ." and ". And that sort of thing. I still think one or the other is the way to go.
 
Let me say that inconsistency in style reduces educational value. I use well-written things to help teach grammar and writing. I could never do that with this piece because of the "mixing". Then again, I've used pieces with problems to do the same. :-)

I agree generally with Stephen on this issue. There are various conventions (I wasn't aware of any being British particularly). A common convention is to use '..........' for quotations and "...." for quotes within quotes; this also uses '..' for scare quotes.
An alternative '''is to use "........" for long quotations and keep '.' for scare quotes.''' This is what I prefer, mainly because in science we tend to use scare quotes quite often (to introduce concepts, or to alert the reader to a different use of a word), and I think it helps to distinguish between these and verbatim quotes. The guide I have to hand says that the choice is a matter of taste, and that "On the whole British publishers prefer single quotes, while American publishers prefer double quotes" (from ''Mind the Gaffe'' by Larry Raske (born NY, living in UK, Penguin books). So maybe I'm American in this? I really don't mind what convention is used, am happy that you make it consistent, and think that the important point for me is only that verbatim quotes are clearly distinguished from scare quotes that mark a 'conventional' use (as these do, indicating that I mean use according to a particular convention, rather than a customary use).
But while I agree generally it can be hard in practice. In the opening it's clear that 'life' and 'living' are enclosed by scare quotes; "Life is what is common to all living beings” is a verbatim quotation. "Life on earth" and "What is life" are really neither, they are pseudoverbatim quotes, probaly closer to quotationa than to scare quotes. [[User:Gareth Leng|Gareth Leng]] 03:25, 17 April 2007 (CDT)

---[[User:Stephen Ewen|Stephen Ewen]] 02:38, 18 April 2007 (CDT)
 
As a general point of policy, I'm going to agree with Stephen and Gareth.  It might be "authentic" (in the sense that it authentically indicates that we are of different backgrounds all working on the same article), but it will also be seen as jarring--frankly, it does to me--by most of our readers.  It will also ''not'' serve our audience well not to have definite (not necessarily singular) standards that CZ articles model.  Do you really want a generation of schoolchildren around the world imitating CZ articles and mixing various styles of English?  I certainly don't want my kid learning a mish-mash of styles when he's writing for an American audience.
 
As to this particular article, I don't care (in principle) about which language is used for general topics, like "Life," but I think we should at least know what the language is.  I think we should keep track of this, moreover.  The question is where we should keep track of it: on the article itself or on the talk page.  David suggested at the top of the talk page; I'd agree with that.  This is also precisely the sort of thing that belongs on the article checklist.  I could easily add a line that would spit out "U.S. English" or something else (tell me what: "Commonwealth English" perhaps?).

So how can we possibly copy edit it? We don't even know anymore what the approved article ''is'' - it's a problem.

==Shortened deadline==
Ive just shortened the approval deadline till the 18th April to clear the decks of the bugs and force us to move onto more productive things. As always, if this is the wrong call I know I'll hear about it really soon. [[User:David Tribe|David Tribe]] 06:38, 17 April 2007 (CDT)

:: -ize words are a problem. It's often thought here that the ize form is American, but actually it's the traditional English form for most such words, though -ise is generally an accepted alternative. So following -ize or -ise should not rationally induce a phobic reaction from Brits. Go with whatever, but go with something consistent.[[User:Gareth Leng|Gareth Leng]] 12:23, 18 April 2007 (CDT)
 
:: OK I've just read it through and I can't see any trace of English English left, though possibly we just read through things after a while without seeing things (sigh). Just for the record, I have absolutely no objection whatsoever to replacing anything with American English. I also have no fixed opinion on the Oxford comma. Just assume I'll go with anything consistent or anything rationally inconsistent (like the Oxford comma when it makes sense). Not aluminum; I won't go with aluminum, if aluminum is mentioned I'll go and grow cabbages. Be careful though not to alter the spelling in the titles of Journal articles or in quotations.

Not to again be stickler -- wait, I take that back -- but this still done got problems. Here's an illustrative one:
 
:How the system behaves as it interacts with its environment determines how these components are organized, and so novel properties of the system 'emerge' that are neither in the environment or in that set of internal components.
 
British "scare quote" comma usage -- 'emerge' (and I have never seen this as an acceptable American style, although I have not seen all American styles, obviously) -- with American spelling -- organi'''z'''ed. Again, me-thinks we need a staunch British English user or American English user to go through this thing top-to bottom.

::I use single-quotes, e.g., 'abcdef', when I want to call attention to the word within.  I might call attention to a word for the purpose of ''mentioning'' the word, as in 'black' has five letters &mdash; I 'mention' the word, or 'refer' to it.  On the other hand, I might call attention to a word in order to alert the reader to my use of a special word, or my special use of a word.  For example, with 'emerge' in the sentence Stephen quoted, I want to alert the reader to something special in the use of 'emerge' there, which special use the sentence partially defines.
 
::I tend to reserve double-quotes for words or phrases or sentences or paragraphs that I attribute to someone, someone the readers knows who by the context or by a source-citation. Also, double-quotes for article titles, as "Notes of a Bird-Watcher", by Robin Feathers.  Book titles like ''On the Origin of Species'' I put in italics.

==TIME AT WHICH VERSION 1.1 DEBATE ENDs==
I agree with Anthony here and indeed was alerted to somethin that Wikipedia puts well. "A three-way distinction is sometimes made between normal use of a word (no quotes), referencing the concept behind the word (single quotes), and the word itself (double quotes):
When discussing ‘use’, use “use”."
 
These are issues of ornamentation more than punctuation (we might have used bold more instead, or italics differently); they're value is only in how within the article they help to make things clear. As I look around in different fields and different media I see different conventions applied to quotes, and many more to punctuation usage. You will certainly needlessly antagonise many authors if you seek to impose a standard punctuation convention, (believe me, I have seen pages written by academics defending their use of the Oxford comma convention and complaining at the copy editors). All the guides I have seen here express very clearly that punctuation is a convention that is subject to preference and different conventions suit different purposes differently. The purpose of any punctuation is clarity, so I suggest the consideration should be whether the meaning is as clear as it can be.[[User:Gareth Leng|Gareth Leng]] 03:31, 19 April 2007 (CDT)
 
:LOL, Anthony. Am I protesting too much?  Perhaps indulge me a bit more. I understand what you described is something you appear to use consistently, but is it more a ''personal'' style rather than some "standard" and published style we can point to, like Chicago and what-not?--homemade style seems the worst possible "manual of style" for an encyclopedia.  I understand that in American English, the only legitimate use of single quotes is for quotes within quotes:
 
:As Sneedmyer contends, "Someone wise once said that, when writing, we should 'choose a style that is standard' and 'be consistent with it' throughout."
 
:Do we all realize how much librarians will freak out when they read articles with apparently inconsistent or personal style?
 
:At any rate, to me what this issue most highlights is that CZ needs to come up with a single yet simple manual of style in these particular regards.

== Question about sentence in 'Cells' section ==
 
The last sentence of the third-to-last paragraph of 'Cells' reads:
 
<blockquote>In the human [[genome]], about 22,000 different genes guide the production of hundreds of thousands of different proteins.<ref>[http://www.ornl.gov/sci/techresources/Human_Genome/faq/genenumber.shtml ''How Many Genes Are in the Human Genome?''] at the Human Genome Project Information website hosted by the U.S. Department of Energy</ref></blockquote>
 
In checking the webpage cited, however, I see no reference to "the production of hundreds of thousands of different proteins".  Also, I do not know what "different" means in that context.  Readers might wonder how 22,000 genes produce >100,000 'different' proteins.
 
Perhaps the citation should relocate to follow word 'genes'.
 
Can someone fix the aberrancy of my thinking. --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 18:32, 18 April 2007 (CDT)
:Nothing aberrant.  Originally there was no cite at all so I added one for the 22,000 figure since that is somewhat controversial.  Actually i did not notice the hundred of thousands of proteins first time around (hence not in the cite).  First, i assume we are talking about primary sequence in this context. If so, is there really that much alternative splicing? I think hundreds of thousands should be changed.  Possibly "upto one hundred thousand" proteins.  Personally i would not count postranslational modifications in the final tally for independant proteins but that type of accounting might be how such a huge figure for the proteins came about (I'd also exclude antibodies from this final figure since those are transcribed from highly specialized cells wit specific geneomic rearrangements). Hope this helps. Certainly i would relocate the cite for now.  Probably there is a better cite with the current gene and protein estimates.  [[User:Chris Day|Chris Day]] [[User talk:Chris Day|(talk)]] 18:56, 18 April 2007 (CDT)
 
::Chris, in response to your comments, I re-wrote the sentence as follows:
::<blockquote>In the human [[genome]], perhaps as few as 22,000 different protein-coding genes<ref>[http://www.ornl.gov/sci/techresources/Human_Genome/faq/genenumber.shtml ''How Many Genes Are in the Human Genome?''] at the Human Genome Project Information website hosted by the U.S. Department of Energy</ref> guide the production of the variety and quantity of protein molecules sufficient to scaffold the structures and functions of a cell.</blockquote>
 
::Change it as you see fit.  We can always edit it further when we get a better citation for cellular protein counts.  --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 22:13, 18 April 2007 (CDT)
 
I see the point; the alternative splicers around me would I think go with Chris, as they are thinking of mRNA. But for me, any example of a protein in a cell that comes to mind is the result of some translational processing. (We talk about the vasopressin gene, but the product is a prohormone cleaved to produce vasopressin, neurophysin and a signal protein.; POMC yields at least eight biologically active signalling molecules including alpha MSH, and beta endorphin that arise by differential processing), In other words when you're talking about "the protein molecules that scaffold the structures and functions of a cell, I think you are indeed talking about the posttranslational products, not the precursors.[[User:Gareth Leng|Gareth Leng]] 02:46, 19 April 2007 (CDT)

Every antibody is a different protein, not a different type of protein, but a different protein none the less. What matters is what's there, the proteins that exist in a living thing, not how it got there (or how they got there)- so, of course post-translational processing counts. [[User:Nancy Sculerati|Nancy Sculerati]] 06:22, 19 April 2007 (CDT)
 
:There are several different things to consider here and it means we need to be careful to define our terms or get a good reference (which will define the terms for us). So how are do biologists define separate proteins with respect to the central dogma? We all agree that alternative splicing will lead to different proteins from the same gene. It is the pesky post-translational products that are the problem.
 
:Processing will allow different proteins to be formed from the same primary sequence. There are many examples, as Gareth pointed out above. But do we include all of these as separate proteins?  When processing is required for the maturation we do not count it as two proteins. Examples of this are proteins with cleaved import sequences and I would also include examples of processing to activate in this category. I think this latter one is debatable and I'm not sure how the proteomics experts categorize these different forms.
 
:Antibodies are a more complicated debate. If each antibody counts as a distinct protein, and they clearly are, then any numbers for the gene to protein count becomes irrelevant because the number of potentially different proteins from one antibody gene alone is hundreds of thousands. Does anyone know how many distinct antibodies are present in a typical human?
 
:In summary, it does not really matter what of the above we count, as long as it is clear to the reader what is being counted. For this reason we need to get a good reference that discusses these issues. [[User:Chris Day|Chris Day]] [[User talk:Chris Day|(talk)]] 10:01, 19 April 2007 (CDT)
 
I had a quick look at the human proteome project page. They are talking about the transcriptome (100,000) and the proteome (1,000,000).[http://ca.expasy.org/sprot/hpi/hpi_desc.html ] This might be a useful link rather than an article since it articlulates the problem well and will presumabaly updated frequently.  [[User:Chris Day|Chris Day]] [[User talk:Chris Day|(talk)]] 11:41, 19 April 2007 (CDT)

==Style, my recent edits==
OK, I've looked through this again after reading Stephen and Anthony. I have tried to apply Anthony's convention in cases where I thought it was absent, and in the process for instance put book titles consistently in italics. I have also tried to reduce the burden of scare quotes, using them as Anthony wants but s little more sparingly where I fett they might be more a distraction than a help. I found inconsistencies in reference style, some spelling mistakes, and a couple of areas where the meaning was not at all clear. My intent with the quotes edits was not to impose my preferences but to a) reduce the burden of any future changes and to remove apparent inconsistencies with the major current use. Not saying I've seen them all.

== chasing our tail (while spinning our wheels at the same time) ==
 
Halting a version for proofing while immediately generating a draft version allows us complete freedom. The creative author (Dr. Sebastian, I presume? ;) ) can keep right on writing in the pursuit of the great article, the copyediters and spell checkers, and Editors who need to smooth out the last idea inserted- that was agreed on in principle- can focus on refining the stable version- ONLY refining. Or, from what seems to be suggested in the forums, we can scratch the whole thing and have ''no'' stable versioning - except for "medical" articles.[ http://forum.citizendium.org/index.php/topic,831.15.htm]l Of course, to me anyway, that is the whole draw of Citizendium- that there ''are'' reliable versions that are not undergoing major construction at any given time. Are we undermining the entire approval process by our inability to work together here? Coming to terms with the Big Ideas in a collaborative process- now ''that'' will always be daunting - and rewarding. But coming up with a proofed copy of an approved article for the wiki? ''That'' should be trivial. Why is it so hard? Why can't we have a simple step by step process for that? [[User:Nancy Sculerati|Nancy Sculerati]] 07:39, 19 April 2007 (CDT)
 
 
Oh I agree Nancy. Trouble is we don't have professional copy editors here and believe me it's a tough job; I recruited those for the Journal of Physiology and worked with them extensively at one time, it's very time consuming to get details right, and virtually impossible to do so while at the same time looking at the meaning. I just don't think we can afford to worry excessively about this, at this stage it's a luxury, when we need to encourage the content givers.[[User:Gareth Leng|Gareth Leng]] 09:56, 19 April 2007 (CDT)
 
:So just freeze the approved article, and let an editor, such as David Tribe, fix the mistakes using his very own sysop powers. A real editor is better than a copy editor, anyway, and a real editor can work with others to make sure the grammer and punctuation are correct English, without losing accuracy of content. When he is done, he announces-I'm done! and we all review it. The moment the approved article was frozen, a draft was generated and those who want to keep writing do not have to wait days or even hours to do so. At that same moment, the editor (David Tribe) in my example, is refining the approved version. The only problem with that is "our rules" against letting an editor use sysop privileges to edit an approved version. It's a stupid rule that demeans the honor of editors and our ability to work. If we could do that, which WAS done (in essence) with the very first biology approval, we would have no problem. [[User:Nancy Sculerati|Nancy Sculerati]] 11:50, 19 April 2007 (CDT)
 
::We have such a rule?  I must have missed that discussion. In the early days i remember DT copy editing the approved version. Was this rule in response to him doing that?

::Nancy, regarding "Of course, to me anyway, that is the whole draw of Citizendium- that there are reliable versions that are not undergoing major construction at any given time."  I would say not 'reliable' versions but 'approved' versions.  And it seems to me 'major reconstruction' prejudices the issue.  I prefer 'revising to improve quality'.  Textbook chapters come out revised in new editions, but one has to wait, and then one still finds the material out-of-date.  With CZ, one gets faster turnover, possibly more up-to-date material.
 
::How can we have a 'proof' version undergoing copy-editing, and a 'draft' version undergoing content and clarity/coherence revision.  How would the edits of the former get into the latter?
 
::Suggest do not nominate for approval until ready for approval except for correcting solecisms, then allow two days for correcting solecisms, so we don't lose our momentum for improving the draft.  The approval tag encourages working on the draft to improve the article.  Let's not tie writers' hands: "Stop working on the piece for a week, while we clean up the bugs."  --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 14:51, 19 April 2007 (CDT)
 
==Cell types??==
200 different cell types???  Nah. Depends what you call a cell type. You only get this kind of number by calling, for example, neurons a single cell type. I can probably count more than 200 neuron types without pausing for breath.[[User:Gareth Leng|Gareth Leng]] 11:44, 19 April 2007 (CDT)

Reminds me of a rather nasty code phrase for a clinic patient so thick that patient education requires the establishment of a new art form- "yeah" says the doc," he's running on 2 Betz cells held together by a spirochete". (or ''she'')-  combined with the assessment of "an IQ just above plant life". [[User:Nancy Sculerati|Nancy Sculerati]] 12:11, 19 April 2007 (CDT) (the preceding are two examples of why we physicians are ''so'' loved by the general public. Except, of course, Dr. House, the TV doctor, who talks just that way and really ''is'' loved by the general public. Go figure.
 
Gareth and Nancy:  Perhaps we can resolve the issue by qualifying the we mean ‘cell types’ based on the findings of histologists who study microscopic anatomy, not  cell function or genotype.  From Valentine et al.’s paper, where I got the ~200 number:<ref>Valentine JW, Collins AG, Meyer CP. (1994) Morphological Complexity Increase in Metazoans. Paleobiology 20:131-142 [http://links.jstor.org/sici?sici=0094-8373%28199421%2920%3A2%3C131%3AMCIIM%3E2.0.CO%3B2-B  Link to Full-Text]</ref><br>
:”As development proceeds in a metazoan, then, cells differentiate in a pattern that is controlled through an interplay of genetic and epigenetic processes. Different genes are expressed (or are expressed at different times or in different doses) in different cells to give rise to a number of distinctive cell phenotypes—the cell types with which we are concerned here. Many cells that have very similar phenotypes, and would be classified as the same cell type, have nevertheless been subjected to different control signals and have had distinctive transcriptional histories, so that precisely the same genes are not necessarily expressed in all members of a given cell type population (see Davidson 1990). Thus, in using the level of the cell type to infer complexity we are indisputably lumping cells that have biochemical and no doubt functional differences. As we are not in fact attempting to measure complexity itself, but are using cell type numbers simply as an index of complexity, this may not present a major problem so long as there is a standard degree of lumping and splitting of cell types to permit a practical ordering of complexity among organisms with different body plans….Histologists have made few estimates of the total cell type numbers of organisms, but they have established a tradition of describing cell phenotypes that has permitted comparative histological studies that have added much to our understanding of comparative anatomy and physiology. Systematists and developmental biologists, interested in the evolution of differentiation and complexity, have been able to draw upon this histological literature to estimate cell type numbers for a variety of organisms across a number of phyla.”
 
So, yes, Gareth, depends on what one calls a 'cell type'.  So we should qualify our use, eliminate the number, or deal with the large variety of functional cell phenotypes, even among cells with the same gene expression pattern.  --[[User:Anthony.Sebastian|Anthony.Sebastian]] [[User talk:Anthony.Sebastian|(Talk)]] 22:42, 19 April 2007 (CDT)
 
==Focus on reapproval==
We have been going some time without achieving version 1.1 approval. It's rather difficult for constables to interpret the commentary here, but as far as I can see, there is no obvious reason for withholding approval, and it would be good to focus editor energies right now on communicating the article's status unambiguously to the constables.
 
Can I ask whether anyone has any reservation about the last edited version? I note cell number remarks are referenced by the Valentine ref, and the protein numbers issue is now now referenced fully. Please be explicit in your responses because are energies are really needed elsewhere I'd say.

Approval

OK, I've updated the version number, and don't see any dissent from approval, so at the end of today, this article will be approved unless there is a last minute objection.Gareth Leng 06:05, 10 March 2008 (CDT)

Thank you, Gareth. In the new version number, I still see a typo or two, and a few wikilinks needed, but I will not edit the current version, so you will not have to update the version number again today. I understand an editor can make minor copyedits to an approved version, but I'll check policy on that if I decide such edits necessary after today's (hopefully) approval. The curse of the perfectionist. --Anthony.Sebastian 14:20, 10 March 2008 (CDT)
Anthony, if you want to go ahead and make the changes that you see I will incorporate them into the re-approved version tonight as long as they are not 'content' edits. Spelling and linking are definitely allowed. I'll just make a note of them on the Approval page. --D. Matt Innis 15:09, 10 March 2008 (CDT)
Thanks, Matt. I made five history-page-recorded edit series since 21:00, after Gareth updated the version number for approval; all corrections of typos or additions of wikilinks. I appreciate your offer to "incorporate them into the re-approved version tonight", but if that means your inserting the edits yourself manually, that seems too much. I'm happy to edit the re-approved version after its up, tomorrow say, assuming I have authorization to do such a thing, and assuming an approved version once up is editable by an editor. If so, you can monitor my edits afterwards. Save you the work. --Anthony.Sebastian 16:35, 10 March 2008 (CDT)
Hi Anthony, those edits are all copyedits, so I will just copy the current draft page over to the approved version with those edits with it. That is no harder than copying the other version, so no problem. You can still make copyedits afterward, too, as the nominating editor. And as always, I look out for anyone changing the approved versions, as you pay me to do ;-) --D. Matt Innis 17:00, 10 March 2008 (CDT)
Thanks again, Matt. I'll stop worrying (and copyediting). I always learn something communicating with you. --Anthony.Sebastian 17:05, 10 March 2008 (CDT)

APPROVED Version 1.2

It appears that we have 3 to 4 approving editors with no significant outstanding issues that were not handled. This approval can move forward.

Discussion for Version 1.2 stopped here. Please continue further discussion under this break.

Looking better every version! I created a third archive as well. If you need to bring anything back, just cut and paste. --D. Matt Innis 22:11, 10 March 2008 (CDT)

old pictures

There are some images from older versions that are not in the current version. Do you think we could put the images in to a gallery subpage so that we can still easily find the images. The one that comes to mind was a picture of a man holding his hands out, I think he was an "evolutionist." Tom Kelly 21:52, 1 June 2008 (CDT)

Tiny typo

This paragraph in the Molecules paragraph contains a weird fragment: "For the possibility of extraterrestrial life based on inorganic matter see novel proposal of physicists Tsytovich et al. A mass of charged particles — like a swarm of bees — exhibiting features similar to Earth-type living systems". Is this the right way to bring attention to this?

Approved?

Citation 35 seems improperly formatted, it shows up as

"Cite error: Invalid <ref> tag; no text was provided for refs named darwin1859"

It is from the section titled "Evolutionary aspects of 'living'". David Finn 11:20, 8 November 2010 (UTC)

Definition discussion

An article on definitions of life. [1] Sandy Harris 01:10, 13 February 2012 (UTC)

Great find, Sandy. I found the 20 comments on the Trifonov article even more interesting.
What thoughts do you have re 'defining life'?
Intriguing: "Living entities can be viewed as bounded, informed autocatalytic cycles feeding off matter/energy gradients, exhibiting agency, capable of growth, reproduction, and evolution." (Orig Life Evol Biosph. 2010 Apr;40(2):221-9. Epub 2010 Feb 19. What is life? Defining life in the context of emergent complexity. Weber BH.)
I keep thinking: Because living systems hasten the pace to maximizing the entropy of the universe, whenever/wherever energy-matter conditions permit, living systems perforce will emerge. Systems that generate more disorder in the system plus surroundings than the order they generate in themselves. The universe longs for its 'heat death'.

Disambiguation, or whatever

This is obviously the primary topic for this title, but I was wondering how to deal with the game. Then I can't find an article here under Games, Mathematics or Computers. Peter Jackson (talk) 06:01, 1 November 2022 (CDT)

Yes, there needs to be a disambiguation page--but, what to name this one? I'll look at Wikipedia and mull options. Any ideas? Pat Palmer (talk) 08:29, 1 November 2022 (CDT)
