I haven't been discussing the analogy, just commenting on Gitt and his "information theory". For some reason nobody wants to explain why Gitt's ideas are relevant to DNA - could it be that everyone already knows that they are not ?

quote: Indeed, as I explicitly stated, I use the language analogy to get the basic points across, but I also explain that above that level, the language analogy breaks down. Unfortunately, many creationists - including those that should know better, such as the "information" hawks - either fail to grasp the limitations of the analogy or ignore tham and use it for propagandistic purposes. I know this occurs - for I have explained the shortcomings of the analogy for, for example, gene duplication, and later seen the same creationist continue to use the language analogy to proclaim gene duplication damaging to evolution.

quote:Yes, I would mind. I was being cautious and tentative when I wrote that. I do not know of any offhand, then, I have not looked into that aspect of duplication. I would say that an example could be Down's syndrome, though that is a bit different than 'mere' gene duplication. However, since the example I gave referred to developmental genes, I think that it holds more import in this discussion (gene dup. as a mechanism of evolution while not necessarily adding information thereby refuting the "evolution requires new information" argument).

quote: Not at all. But it seemed to me, as Percy rightly explained and I alluded to, that the questions were intended not to learn more, but to find ammunition. On another forum, a creationist was aghast that I did not agree with his sentiment that there was nothing wrong with asking questions in class designed to make the professor look stupid (yes, those were his words - 'to make the prof look stupid.'). Can you see why I would not agree with that sentiment, and why I find litle reason to 'respect' someone that does?

quote: I thought I sent that to moose?Well, I was angry, for it seemed that I was getting made an example of. Though I do not think I used the phras "two-bit".... quote: Indeed. I hate to keep bringing up other boards, but in my experiences elsewhere, I have found nice examples of many of the things that get brought up here. There is a poster named "bertvan." She is active of the ARN forum now, and used to be very active on the old, old incarnation of the Internet Infidels board several years ago. She was probably the most frustrating creationist I have encountered. These were the days when I would take sometimes hours to dig up refs and write lengthy posts to support my points. Bertvan would ask some question (or more usually, a series of questions), I (and others) would take the time to address each of them in detail, and she would blow off 99% of your post, and just focus on some minor trivial point, or ask more questions on just one of the many responses, then refuse to even entertain the other informaiton provided to her. (She still does this - she is now a proponant of EAM, which is similar in a way to GUToB except without the imaginary particles. One of the basic tenets of EAM is directed mutations. Back when I posted on ARN, I provided with a list of citations similar to the one I provided Borger on how these mutations do not occur. She ignored it. she has recently been presented with similar lists on many occasions. She drops the thread, only to bring up the same issue later...). Sonnike is not yet to that stage, but he is getting there. We are getting along much better, but it is difficult to keep it up when the opponent refuses to discuss the issues they bring up...

quote:quote: I think so...quote: Duplication of the Hoxd11 gene causes alterations in the axial and appendicular skeleton of the mouse. : Boulet AM, Capecchi MR. : Howard Hughes Medical Institute, Department of Human Genetics, University of Utah, School of Medicine, Salt Lake City, Utah 84112-5331, USA. : The Hox genes encode a group of transcription factors essential for proper development of the mouse. Targeted mutation of the Hoxd11 gene causes reduced male fertility, vertebral transformation, carpal bone fusions, and reductions in digit length. A duplication of the Hoxd11 gene was created with the expectation that the consequences of restricted overexpression in the appropriate cells would provide further insight into the function of the Hoxd11 gene product. Genetic assays demonstrated that two tandem copies of Hoxd11 were functionally indistinguishable from the normal two copies of the gene on separate chromosomes with respect to formation of the axial and appendicular skeleton. Extra copies of Hoxd11 caused an increase in the lengths of some bones of the forelimb autopod and a decrease in the number of lumbar vertebrae... "Give me a hug" "Give me a mug" "Make a limb this long" "Mak a limb that long" The two are not really directly analogous. "Give me a hug""Give me a hug" = the guy really wants a hug HOX11D = x-number of vertebrae, limb length Y HOX11D HOX11D = x-n number of vertebrae, limb length Y+n Not analogous, either. As I said, the language analogy is good fopr getting basic points across, not very good as describing events related to complex gene action/evolution.quote:And this questionis leading where? Yes, it was a "directed" experiment - how else are experiments to be done?However, gene duplications happen all by themselves. LOTS of them. In fact, huge blocks of the human genome are the result of large scale duplications. quote:Percy agrees, it seems to me, with me on the analogy issue. It appeas that the mutations we can characterize are either neutral of harmful. This is the question I have asked many a creationist - how do we find beneficial mutations? It is easy (relatively speaking) to find the genetic componant of disease. But how do we find the genetic componant behind, say, not getting a disease? (actually, this has been done - a mutation in a cell surface receptor allowed many to avoid plague in the 1600s, and that allele now confers similar health benefits to the descendants of those with the allele; also, similar mutations confer immunity to HIV infection).The evidence that gene duplications etc. can and do cause phenotypic change is there. That a human is not born with wings or some such nonsense is not evidence that beneficial mutations do not occur. I will grant you this - at least you are getting some non-biased information for a change. That is a good start. Now throw out your Gitt book....

S:How does evolutionary thinking explain such control mechanisms?, ie. how they evolved.
In other words, this is pure faith in the hopeful powers of mutation and natural selection. I appreciate your honesty, but it really leaves me asking why don't you want to know for sure.---------------------------------------------------------------------- SLPx:I don't know, personally. I would assume, however, that the same way everything else did - mutation of some sort followed by selection of some sort. Is this something science is basically silent on? Evo's are always challenging creationists to provide solid evidence and proof. It's becoming apparant that there is a lot more "faith" in the "scientific" community about certain things, than is openly admitted to. Am I correct? You didn't really respond to my latest posting, from last night, did you see it? Also, I'm thankful were getting along better too. I'm honestly not out to make anyone look stupid. I think there are a lot of unanswered questions, and obviously the answers aren't known yet. We'll keep talking. Regards,S ------------------Signature too long, 200 chars max. p.s. sorry, just as I posted this I saw your response..stand by.p.p.s I see "they" are now limiting our signatures.... grrr [This message has been edited by sonnikke, 02-26-2003]

Now throw out your Gitt book....
Actually I have a confession....I don't have Gitt's book or Spetner's...I want to get them though. maybe then I'll be able to respond better to the Gitt remarks.
"Give me a hug"
"hug her" "Give me a mug""mug her" entirely different and not easily deduced. Right? Regards,S

quote: Pardon my frankness, but it is this kind of bullshit response that formulates my negative impressions of creationists. The objective reader will notice that I wrote the word personally. That means that I, SLP, PERSONALLY do not have that information handy to disseminate. It does not mean that there is no answer at all or never will be, nor does it mean that I don't "want" to know the answer, it just means that I do not PERSONALLY have that information. Let me explain something to you, Sonnike: Despite the fact that the creationist propagandists at AIG and such will write about any and every topic under the sun and present themselves as being 'experts' therein, any field of science is prohibitively large and broad to allow any one person to be 'expert' or even knowledgible in all areas, even those closely related to their true area of expertise. The question you are asking is a theoretical one - you asked for how "evolutionary thinking" explains it. You said nothing about "evidence". You said nothing about "proof." You said "thinking." I am not involved in that line of "thinking." And so, being much more honest than the ReMine's and Sarfati's of the world, I simply say that I PERSONALLY do not know, and then I give my assumption - my 'thinking.' Then, as a good little creationist is wont to do, you try to turn it into some idiotic "look - you just take it on FAITH blah blah blah" BS. How is it again that I am supposed to respond to you when you pull this sort of crap every other message? With "respect"?quote:See above quote: You are quite wrong. Again, that I or some specific individual does not have a ready-made answer to any and every question that some creationist can come up with is hardly indicative of the status of an entire scientific field. To imply as much is indictive not of someone trying to learn, but of someone trying to validate their own preconceived notions - of someone more interested in proselytizing and propagandizing than learning.quote: Are you kidding me? Shall I go back through this thread alone and ask you why you did not respond to all of the points that I brought up? I can guarantee that my list would be about an order of magnitude longer than yours...quote:Maybe you spoke too soon. I am willing to keep this civil, but this conclusion jumping and ammo-searching needs to stop. AGAIN, that I PERSONALLY do not have an answer to your every question cannot by any stretch of the imagination be construed to mean that there is some "crisis" in evolution or that all evolutionists just take everything on "faith." I am not a pharmacologist, but I still take penicillin if I have strep throat. Does that mean that I am just taking it on faith? That if I - or more analogous, the pharmacist - cannot explicitly and immediately explain exactly how this penicillin will help me fight off the streptococci in my throat that the whole pharmaceutical industry is premised on nothing more than faith? Come on, Son....

I'm not even going to quote that ranting scenario you just exhibited.
Your accusations are projections of the same kind of questioning/statements that evo's are "guilty" of. Apparantly I touched on a very sensitive nerve which I "obviously" shouldn't have. It is not only discouraging but also dissatisfying to receive such insulting responses to what I genuinely meant as honest inquiry. If you want to live in your own little world and not talk to anyone else who differs from you or questions your beliefs, then frankly I am at a loss as to why you even bother. Do you think I am just going to say, "gee Dr. Page, you're right, evolutionism is the answer". No, and I don't expect you to do the opposite. What I did expect was the same kind of honesty you briefly showed, but apparantly you felt that it threatened your community. I'm trying more and more to answer your questions, which requires much research and learning on my behalf, as I have not been schooled in genetics for years and years. If you or anyone, can't take a little questioning without fearing your paradigm is lost, well, then maybe it's time to re-think your paradigm. Sonnikke

Hi Sonnikke,
I saw Scott's reply to this message, and your reply to his reply. Scott's post *was* a rant, but it was also accurate. Look at your reply again:
Sonnikke writes: S:How does evolutionary thinking explain such control mechanisms?, ie. how they evolved. ---------------------------------------------------------------------- SLPx:I don't know, personally. I would assume, however, that the same way everything else did - mutation of some sort followed by selection of some sort.

Evo's are always challenging creationists to provide solid evidence and proof. It's becoming apparant that there is a lot more "faith" in the "scientific" community about certain things, than is openly admitted to. Am I correct? As Scott has already explained, these conclusions and questions don't follow from Scott not knowing something, and when inserted into the middle of what was becoming a serious and productive discussion it just looks like you're looking for the faintest excuse to declare evolution faith-based and be done with it. Look at it this way. Ask yourself if you know everything about your religion. You don't, do you. Maybe there's an area of your religion that you're an expert in, but you're not an expert in all of it, are you. You rely on other experts in other areas, don't you. You rightly believe that the religious questions you don't have answers for *do* have answers, and that the experts in those other areas could provide those answers were they available to ask. And the fact that you personally do not know everything about your religion does not mean your beliefs are founded upon nothing but faith with no evidence or reason, does it. And you'd think it pretty rude if someone inserted such a conclusion into the middle of a serious discussion, wouldn't you. I hope you two can resume the discussion. --------------------EvC Forum Administrator

Let me try again.....I'm really not quite sure how to respond to a statement like Scott's.Admin, if you'd indulge me, pretend you are a creationist for a moment, how would you respond to Scott's statement? Thanks, Sonnikke p.s. I'm serious about this request.

Speaking personally I would say that an honest and rational creationist - indeed any honest and rational human being - would have to admit that there was insufficient information to come to any reliable conclusion.
Any pro-creation response would have to be a "God of the Gaps" type argument with no better foundation than personal incredulity.
