On the Second Law of Thermodynamics
by Means of Mammals and Fleas or The Preservation of Good Ideas in the Struggle for Sanity Imagine a sealed room with a flea infested panda sitting next to a flealess tiger. Imagine further that the fleas jump from one to the other randomly. Obviously, in the beginning there will be more fleas jumping from the panda to the tiger than vice versa. But as more and more fleas jump to the tiger, some fleas will be jumping back to the panda. Eventually, a situation will be arrived at with equally as many fleas on the panda as there are on the tiger. The fleas keep jumping to and fro, but the situation overall will be in equilibrium. The system (comprised of the panda, the tiger and the fleas) has gone from minimal entropy (i.e. minimal disorder: all fleas on the panda) to maximal entropy (i.e. maximal disorder: fleas equally distributed between both animals). Will there ever again arise a situation in which there are more fleas on the panda than there are on the tiger, or the other way around? If the situation stays exactly as described above then the answer is no, it will never happen. But what if we add some energy to the mixture, what will happen then? Well, let's try. We'll open up the sealed room and set fire to the tiger. The fleas on the tiger don't relish being burnt and jump to the panda more readily. The fleas on the panda no longer smell a fresh tiger nearby, but a smouldering one, and they forego the jump. The result is that the fleas end up, en masse, on the panda. It's amazing what a little heat can do. There is grandeur in this view of science, with its several laws, having been originally thought of by Some Scientists in some form or other; and that, whilst this planet has gone cycling on according to the laws of Another Scientist, from so simple a beginning, endless science most beautiful and most wonderful has been, and is being thought of. "Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science." - Charles Darwin.

But, there is so much noise that regardless of beenficial and deleterious mutations, they do not get spread around as much as they would if there was no noise. So in reality, when we take the effects of noise into considerations, we almost always have genetic drift, as opposed to positive selection working. Meaning, beneficial and deleterious mutations are equally likely to spread through the population. quote:NO! How many tiems do I have to say that geentic entropy does not always have to equal loss of fitness? The point is that the chain got shorther. Because of mutations. And the more time went by, it got shorter and shorter. The longer ones died out. And only the shortest were left. Clearly demonstrating that evolution does not work. You can't get a human from RNA chains by this process becasue they are losing not gaining complexity.

Than we describe it as a "bidirectional rotary motor-driven propeller". quote:After that, we define all relevat chance hypoteses, which include Darwinian evolution of the flagellum. quote:After that, we take into account the possibility that the flagellum can be perturbed. The number we take in to account is the 20 orders of magnitude. Becasue it could be possible to mutate the flagellum so it would still be functional. And after that we simply look at teh number we get where teh probability of the flagellum forming by chance has been calcualted from NFL. The number we got is 1:10^2954. Therefore, since we know that the universal probability bound is 1:10^120. It means that the flagellum has less chance of forming than the universal probability bound. Which means it was designed.

Smooth Operator's key argument is that both deleterious and beneficial mutations reduce the amount of information in the genome, cause a reduction in function and specificity, and increase genetic entropy. I suggest that both sides keep their posts short and focused on these points.

What got changed, the ribosome or the streptomycin? Obviously the ribosome. Therefore, it is the one that lost specificty. Except that sequence wasn't evolved to have specificity to streptomycin. If I shape my hand to fit into a particular hand hold when climbing a rock have I suddenly increased the rock's 'information' because I have specified my hand to fit it? You seem to be saying that as soon as the full streptomycin biosynthesis pathway had evolved the specified information content of the ribosomal genes jumped despite there being no change in its sequence, we might consider that information to have been 'free' since it only served the function of the antibiotic rather than the ribosome. I don't see why this is more logical than me suggesting that it can lose that binding specificity without losing information content. All you seem to be doing is highlighting why your conflation of the specificity in CSI and binding specificity is meaningless when you don't actuslly look at the functional biological context. Once again you are making up a system where things can't help but 'degenerate' because you are defining any change from the initial state as degeneration. Would you consider any mutation which increased binding affinity to anything to therefore represent an increase in information/CSI? Even if the subsequent binding served no functional purpose for the mutated protein? You are just showing us why these creationist/ID measures of information divorced from actual considerations of function are totally useless. They are just ad hoc measures based on arbitrarily selected starting points and in many cases arbitrary criteria for what constitutes a gain or loss of information. Remember the Durston et. al FSC measure we discussed, where they base their estimates essentially on conservation, totally regardless of actual functionality beyond very crude classification. Their method means that any novel mutation which allows the maintenance or even improvement of function for a protein nevertheless would represent a loss of FSC. There is no possible route in their approach which allows a novel mutation to produce an increase in functional information. TTFN, WK Edited by Wounded King, : No reason given.

quote: My point is that we do not know whether the mutated enzyme had no function or if it did. That is what I said. Perhaps you should try harder to remember just what you are arguing against ?
quote: In other words, your real "specification" is the E Coli flagellum plus near variants of it. And as I have pointed out, this is a fabrication. (The probability calculation is wrong, too, but that isn't important now).
quote: Since actually doing the calculation would be a complete waste of time, why exactly do I need to explain how to do it ? After all, I don't care whether you do it or not.
quote: If D is "bidirectional rotary motor-driven propeller" then it makes no mention of 50 proteins. That is just an unspecified detail read off the event (i.e. fabrication). The "complexity"(or rather the information content) is calculated from the probability (it's -logmax(P(D|H)) over all possible explanations H). That's Dembski's method.
quote: Exactly - because Dembski was right and the correct probability is P(D*). Which does not permit adding in details that are not in the specification D.
quote: Obviously if the information was only input in the creation of the first E Coli (or it's ancestor) it cannot also be input in the ordinary operation of the growth mechanisms.
quote: Natural sources do not produce Complex Specified Information in Dembski's sense (or rather they almost certainly do not, even if Dembski were entirely right). However we cannot work out if something is Complex Specified Information by Dembski's method without looking into its origin. By Dembski's definition, natural sources can and do generate information, even complex information and specified information (because his measure of information is simply an measure of improbability). So, without applying Dembskis method to this information, we cannot work out whether it is CSI or not. And if it is not CSI - if the specified part of the information (D*) is not complex - then, according to Dembski, it could have a natural source.
quote: Even if it is the case that the frequencies are constant (and I'm far from certain of that), it isn't the same sort of selection as applies to sickle-cell. Which means that all you are really doing is pointing out the weakness of drift in large populations. Remember, it was you who introduced sickle-cell as an example of a beneficial mutation (and even claimed that it was spreading), so comparing it to neutral mutations really misses even your own point.
quote: This is the same noise that - according to you - is having absolutely no effect on the frequency of hair or eye colour. Which means that it isn't going to have much effect against selection either.
quote: For that to be true, the effect of drift would have to be so strong as to completely overwhelm selection. To be entirely true it would mean that there were no advantageous or deleterious mutations at all. All mutations would be strictly neutral. A completely sterile individual would - on average - have the same number of offspring as the best and most fertile member of the population. Obviously that cannot be the case. So since it can't be entirely true, the question is, how close to the truth is it. What is the evidence ? Is it so weak as to have almost no effect - as you claim, or so strong as to completely overwhelm selection - as you claim.
quote: The number of times you say it, doesn't matter. Genetic entropy IS a cumulative loss of fitness, leading to mutational meltdown and extinction.
quote: Aside from the fact that that is going well beyond what the experiment can reliably tell us, it isn't even relevant to the real point. You claimed that it was evidence that genetic entropy increases. And it isn't. The monster beat genetic entropy.

The number of times you say it, doesn't matter. Genetic entropy IS a cumulative loss of fitness, leading to mutational meltdown and extinction. This is such an important point. Unless SO is talking about a totally different concept of Genetic Entropy from Sanford then it must absolutely be about actually deleterious mutations and decreases in fitness. Abstruse notions of beneficial mutations which reduce some unmeasurable notion of information are totally beside the point. TTFN, WK

This just shows you do not know, you actually still don't know what gentic entropy is supposed to be. It's teh deterioration of genetic information in the genome. This relates to Muller's Ratchet. "The theory of Muller' Ratchet predicts that small asexual populations are doomed to accumulate ever-increasing deleterious mutation loads as a consequence of the magnified power of genetic drift and mutation that accompanies small population size."--source However, the evidence indicates two things. First, compensatory mutations arise which ameliorate the effects of slightly deleterious mutations: "Isolates encoding DRSeq3 also show lower ND5 deletion levels, though the difference as compared to those that encode DRSeq1 is not significant (P > 0.10, two-tailed t-test). When considered as groups, mean heteroplasmic deletion levels were higher in tropical-clade isolates (12.1%) as compared to temperate-clade isolates (7.3%), though the difference was not significant (P > 0.9, two-tailed t-test). We also analyzed fecundity variation with respect to the three sequence motifs and found that isolates encoding DRSeq2 displayed significantly elevated fecundity as compared to those encoding DRSeq1 (P < 0.001, two-tailed t-test) — see Figure 4C. Fecundities in isolates encoding DRSeq3 and DRSeq1, however, were highly similar and not significantly different (P > 0.1, two-tailed t-test). The relatively low ND5 deletion proportions and high fecundities associated with isolates encoding DRSeq2 are suggestive of compensatory mutation — in particular, the ND5-2 substitutions are expected to result in reduced interactions of directly repeated sequences in ND5-2 and ND5, thereby resulting in lower ND5 deletion incidences and higher fitness. However, we are again unable to account for the potential effects of nuclear loci."--same source as above So the first mechanism to overcome genetic entropy are mutations which increase fitness. That is, beneficial mutations. The second mechanism is negative selection. That is, those with the highest deleterious mutation rate are selected against. This ongoing process stops Muller's ratchet. "A decrease in nucleotide substitution rates over time suggests that selection may be limiting the effects of Muller's ratchet by removing individuals with the highest mutational loads and decreasing the rate at which new mutations become fixed."--source Like a CD. Copying it enough times, over and over again, to a new CD, and than take that one and copy it again, and this is going to add few mistakes here and there. Over enough time, enough information will be lost and the CD won't be useful anymore becasue you won't be able to read anything from it. In order for this to be an accurate analogy you need a source of selection. Edited by Taq, : No reason given.

What got changed, the ribosome or the streptomycin? Obviously the ribosome. Therefore, it is the one that lost specificty. Would a gain in specificity be a gain in specified information?
Both show beneficial mutations increasing genetic entropy by degrading biological functions.
Would a gain in function be an increase of specified information?

The second mechanism is negative selection. That is, those with the highest deleterious mutation rate are selected against. This ongoing process stops Muller's ratchet. Another important element in this is the existence of synergystic epistatic effects, where the fitness burden of multiple deleterious mutations is greater than the product of their effects in isolation.

Well than, a perfect exmaple if here. http://www.designinference.com/.../2005.06.Specification.pdf We know that the flagellum consists of 50 protein parts. Than we describe it as a "bidirectional rotary motor-driven propeller". Try and pay attention, SO. Nuggin wrote:
If Creationism is the _ONLY_ example, then this is not a valid way of evaluating it. It's like having a "Zimzom Detector" which is the only thing which detects "Zimzoms". Can't prove it right or wrong. That may look familiar since you copied it onto your post as well. You CAN NOT use Creationism as an example of something which is NOT CREATIONISM to test against CREATIONISM. I was EXTREMELY specific in my request. Give us something OTHER THAN CREATIONISM which demonstrates design without knowing mechanism so we can VALIDATE your claim about Creationism. And the _ONLY_ example you can come up with is... Creationism. Again. Is Creationism the only thing that the magical wizard designed? Is it the only thing that CSI (or any other method) can determine was designed? If so, CSI is just another Zimzom Detector.

I'm listening. Explain what's wrong with my description. That it's wrong. It's as though you said: "The Second Law of Thermodynamics says that there's a unicorn in my backyard playing the trombone". Well, no it doesn't.
Pace Percy, I don't think that I have to teach you a beginner's course in thermodynamics to explain to you why that is not what the Second Law of Thermodynamics says.
But genomes still do not degrade right? There is no genetic entropy? If we use Sanford's definition, then genetic entropy does not occur except in very small populations.
This just shows you do not know, you actually still don't know what gentic entropy is supposed to be. It's teh deterioration of genetic information in the genome. I note that your reply was not an answer to anything that I actually said. This leaves me with a problem. How do I converse with someone who is not actually talking to me? I guess I'll just taunt you once again with the fact that you cannot quantify "genetic information" or "genetic entropy".
Very well, let's see what Sanford has to say about that... I have already acknowledged the fact that Sanford is wrong. My point is that mistake is different from your mistake. You have quoted him talking halfwitted nonsense about beneficial mutations. Very well then, I admit that he is a stupid liar. But the mere fact that he is a stupid liar does not prove that his definition of "genetic entropy" is in agreement with yours. The mere fact that he is a stupid liar does not in itself prove that you and he are in agreement.
This article claims you can't invoke beneficial mutations to save the mopulation. Even the large mammalian populations. No it doesn't. This is why you can't quote any part of that article that supports your fantasies.
I just did, above. I can't wait to see what you have to say to that... That your trash is different from Sanford's trash.
No, they are not extinct YET. But it seems that they will follow those that are extinct. Yes, according to you this might happen if we wait ten billion years. But even if this daydream was true, it would not contradict reality.
How is it not opposed to evolution? If your definition of increase of genetic entropy includes every event that biologists claim has taken place, then you are not arguing against biology.
It's not a falsehood. You do seem to think that darwinism equals evolution. You are still telling me blatant falsehoods about my own opinions, and you will never succeed in deceiving me.
Do you also agree with him that darwinism only, can not account for all diversity of life on Earth? Where did Kimura write that "darwinism only, can not account for all diversity of life on Earth"? Actually, that's an unfair question, since the moderators have decided that your repeated and ridiculous untruths about Kimura are off-topic. I suggest that if you want to tell blatant, absurd, and libelous falsehoods about Kimura, you should start a new thread.
What about those links I posted that actually showed the genetic meltdown occure? Your links showed strong experimental evidence that genetic meltdown does not occur except in populations which have been artificially reduced in size.
But this kind of evolution can not be extrapolated to be evidence for a darwinian evolution leading from a single cell to a human. I guess that's why I never in any way said or implied that it could.
Mybe it wasn't. I don't know if it was. But I do know of cases where bacteria aquired nylon digestion by transposons, so I said that it could be caused by one this time also. It doesn't really matter to my argument if it really happened that way. We are already aware that facts don't affect your arguments.
I never said you are confused. Your statement is of, course, untrue. Here is the post where you said that I was "confused". I find you people hard to understand. Obviously, you need to deny reality --- you're a creationist. But you go further than that --- you gratuitously deny reality. You make false statements when you know that you're going to get caught and exposed. Obviously, everyone reading this thread knows that your statement is false. You know that your statement is false. And, this is the thing that I don't quite understand about people like you --- you know that everyone else knows that your statement is false. You can be absolutely certain, without any shadow of a doubt, that everyone reading this thread will know as a matter of complete certainly that you are not telling the truth. So, why do you do it? This is the question that eats away at me. You know that everyone reading your posts knows that what you are saying is not true. So why bother saying it? The only conceivable function it serves is to let people know that you hate the truth. But surely that is not your objective. It is surely not your goal to persuade people that you should be an object of contempt and mockery. So ... so why do you do it? Edited by Dr Adequate, : No reason given.
