quote: I will only comment that you were interested enough in the claim that it had lost ALL function to try to dispute the point.
quote: Wrong ! D* = the set of bidirectional rotary motor-driven propellers". Your 10^20 is Dembski's estimate of the number of four-level concepts, as your quotes showed.
quote: No, and the probability of getting some "bidirectional rotary motor-driven propeller" - the probability that we actually want - is different from both of them.
quote: Where "Yes, exactly" means "No". All you have done is repeat the same grossly erroneous claim. 10^20 is Dembski's estimate of the number of 4-level concepts, of whichbidirectional rotary motor-driven propeller is one. quote: No, the probability of E is not important. Only the specified information matters. And that is derived from the probability of D*.
quote: You can't even get the probability of rolling two 6s on 2 dice correct. It's 1/36. Besides that your whole argument deals with irrelevancies. We want to know the probability of getting ANY "bidirectional rotary motor-driven propeller", not one using a particular number of proteins, because the number of proteins is not part of the specification,.
quote: Do you want my help or not ? If you want it then all you have to do is to provide the information I ask for. Remember I'm only doing this as a favour to you. If you can't be bothered to look up the details of the calculation then there's no reason why I should.
quote: I'm afraid that it does. Look up Dembski's definition of specification again.
quote: I will observe again that you cared enough to try to argue against it. Even if you did not care enough to actually address the reason why it is unusual (which is the dodging). And in fact there is a reason why you should care. If sickle-cell is not a typical example of a beneficial mutation it cannot be used as such.
quote: Of course this argument is absurd since it equates increasing fitness with declining fitness. And your main example - sickle-cell is atypical, and so can't be used.
quote: The field of statistics would disagree with you. It is a fact that given a large population (of samples) noise will tend to average out - because it is random.
quote: I'm not arguing for a "full removal of mutations". Just a dynamic equilibrium where the number of deleterious mutations maintained in the population falls short of mutational meltdown. The other problem is that you are now assuming that drift dominates to the point where there is no selection at all. I suggest that you produce evidence for this bold claim. (And yes, I know that you didn't mention correlation because I know that I brought it up. Because you need correlation to avoid the averaging effect of large populations.)
quote: Wrong again. 100% efficiency would produce guaranteed removal of all deleterious mutations when in fact some can reach fixation. Unfortunately accumulation requires more than that - it requires that there cannot be a balance point, where the rate of removal of deleterious mutations equals the rate at which more enter the gene pool. However, by your own admissions all surviving organisms must at least be close to such a point (because the rate of accumulation must be very, very slow to explain why life still survives). And if it is that close the evidence offered so far cannot tell us that the balance point has not been reached in at least some species. I will reply to your comments on the monster only to point out that I make no admissions. I simply decline - in deference to the preferences of the site owner - to add another subject to this discussion. Edited by PaulK, : No reason given.

quote: Actually it doesn't tell you much. (And it tells you nothing unless you know what Dembski means - something you have been highly resistant to learning). In fact the two could be done in any order, but there are practical reasons why you would almost always check that the observed pattern is a valid specification first.

quote: No, I'm warning you that you don't know what you are talking about. There is no "specificity of an object" in Dembski's method, nor is complexity calculated by comparing objects. The quote doesn't help you because it is talking about a method that is quite different from whatever it is that you mean. If you can't be bothered to learn what Dembski's method actually involves then you really really ought to stop talking about it - and attacking people who try to explain it to you.

quote: No, that is the position you retreated to, after it became clear that you did not have the evidence to rule out all function.
quote: No, D is the descriptive pattern. Strictly speaking D* is the pattern considered as an event - or put another way the event of matching the pattern. But given that we have a physical object rather than the event, in this case regarding it as the set of objects which match the pattern is quite reasonable. Certainly more reasonable than equating it to a number as you did. Let me remind you:TDI p165
..the event that needs to have a small probability to eliminate chance is not E, but D*
The four-level concept is also easy to understand. It is a concept made up of four elements. In this case "bidirectional", "rotary", "motor-driven" and "propellor". Dembski allows for 10^5 possible elements, therefore estimating the number of four-level concepts as (10^5)^4 = 10^20. Look at your quote in Message 688
For a less artificial example of specificational resources in action, imagine a dictionary of 100,000 (= 10^5) basic concepts. There are then 10^5 1-level concepts, 10^10 2-level concepts, 1015 3- level concepts, and so on. If bidirectional, rotary, motor-driven, and propeller are basic concepts, then the molecular machine known as the bacterial flagellum can be characterized as a 4-level concept of the form bidirectional rotary motor-driven propeller. Now, there are approximately N = 10^20 concepts of level 4 or less, which therefore constitute the specificational resources relevant to characterizing the bacterial flagellum.
"Specificational resources" is essentially the number of possible specifications. It in no way compensates for the fact that the specification describes many things that are not the E Coli flagellum.
quote:There is no word "set", anywhere. D is the descriptive language. D* is the pattern that describes the event E. Remember that. [/qute] If you actually READ the quote you will see that the pattern is D, and D* is the correspondence of the pattern.
quote:Again, it's a pttern. D* is a patternt. Not a SET of patterns, but a pattern. [/quote] In this quote the pattern is (D, *), whereas in the first it was D. Neither is D*. D* is not described as a pattern. It is, however, described as an event on p165 quoted above.
quote: As the quote I have produced above makes clear, 10^5 is the number of basic concepts. It is not the "complexity". And it certainly is not the probability of D*, which is what Dembski say must be calculated.
quote: Yes, the probability you want to calculate is different from the one that Dembski says that you should calculate. And I think that it should be obvious why you should calculate the probability required by Dembski's method - the probability of D* - rather than some other probability of an event which isn't even fully specified.
quote: As I have told you before the complexity figures are associated with the specifications rather than the raw events. This is because the relevant probability is the probability of meeting the specification - i.e. the event D*, as Dembski says.
quote: As I keep pointing out the probability we want is the probability of getting ANY "bidirectional rotary motor-driven propellers". See the quote from TDI above.
quote: I understand what you are talking about. I'm just not going to do the work for you. You would need that information to do the calculation anyway. Of course as I have informed you more than once it is a complete waste of time because it's the wrong probability anyway.
quote: Simple patterns ARE specifications. They are very good specifications. Consider the Caputo case. If the Democrats had been placed first on the ballot EVERY time, wouldn't that give more reason to suspect tampering, rather than less ? With a snowflake the problem is that we don't have a specification that provides a detailed description of a particular snowflake. Again, check the definition of specification.
quote: However that was not the point being argued. You wanted to argue that beneficial mutations in general increased genetic entropy. Which you can't do by relying on an atypical example.
quote: If you've run the numbers - and you would have to to make such a claim, let's see the calculations.
quote: You've cited articles saying that mutational meltdown can happen in small populations. Which implies that it is unlikely to be a problem for larger populations. And you are quite wrong to say that the balance requires 100% efficiency. It doesn't. All it requires is that the efficiency is high enough to hit the balance point before mutational meltdown.
quote: A correlation would mean that we could not assume that the noise will tend to average out.
quote: Wrong. The balance point is where deleterious mutations leave the population at the same rate as they arrive. Removing a deleterious mutation that has hung around for 50,000 ears - or longer - is as good as removing one that appeared last week. We don't need 100% efficiency for that.

quote: So now - after trying to pretend that you didn't say it, you are going back to the same illogical argument. In fact you don't know whether the mutated version had lost all function or not. The tests weren't done. And even if they had been they would only apply to the version tested, and 20% difference allows for a LOT of different versions.
quote: However the quote I was actually talking about said that D was the pattern. Expecting me to ignore the quote I am talking about and look at some other quote instead is really stupid.
quote: I'm not inventing notions that Dembski never used. And you are forgetting the quote from p165 where it describes D* (which is NOT D, remember !) as an event.
quote: No, it doesn't mean that. D is "bidirectional rotary motor-driven propeller. D* is the correspondence of D and 10^20 is the number of four-level concepts.
quote: Which specification describes what ? The specificational resources aren't described by a specification. The specification I referred to is - as you ought to know by now - is "bidirectional rotary motor-driven propeller".
quote: Since it specifically says that the pattern is D, it doesn't mean that D* is the pattern.In fact neither quote says that D* is the pattern. They don't agree on what the pattern is, but that's Dembski for you. quote: Well you're still wrong, it's the numerical value used to quantify the specificational resources.
quote: I can only repeat that the complexity belongs to the specification, not to the event. As Dembski tells us, we calculate the probability of meeting the specification, not the probability of a partially specified event. Also an event may have many possible specifications which have different probabilities. And I have to add that MY logic doesn't say that the probability of getting each of the events described by the specification is the same as getting any particular one. Excepting the degenerate case where there is only one possible event that fits the specification that will always be false. My logic says that the events will often have different probabilities - but the difference is down to unspecified details which are not relevant to determining if the event is CSI.
quote: But you will still have to combine them to get the probability we want. Remember we want the probability of getting ANY of these, not the probability of getting a specific one.
quote: If any one of the results comes to less than 2^-400 you had better abandon the whole thing since the probability of getting a "bidirectional rotary motor-driven propeller" is at least as high as the probability of getting a particular "bidirectional rotary motor-driven propeller". Time to give up on that specification, rather than fiddling the figures (which is what your suggestion amounts to).
quote: The point is following Dembski's method. Arguing that we shouldn't do it because it doesn't guarantee getting the result you want is just silly.
quote: The pattern IS the specification. Simple patterns are usually the best specifications.
quote: In fact you originally argued that nearly all beneficial mutations contributed to genetic entropy - using sickle-cell as your main example. And as I have pointed out before your argument fails because genetic entropy is about reducing fitness and beneficial mutations (by definition) increase it.
quote: I could point out a number of flaws in the premises and reasoning, but the really fatal problem in your response is that you are addressing the wrong problem. The question is about the averaging effect of a large population in reducing the effects of "noise". You claim that there is no averaging effect (presumably meaning no significant averaging effect). However since the effect must be there to some extent, the only way to find out how significant it is is to use the numbers as they apply to real populations. Even if you were attempting to answer the actual problem instead of a completely different issue, you would need data and calculations - not theoretical speculations.
quote: Unfortunately we aren't talking about the tests. We are talking about a general statement giving background information. A statement which specifically identifies it as a potential problem for small populations.
quote: I was specific. A correlation between a mutation and one of the other factors you identified as influencing the selective process, such that a deleterious mutation would have a consistent advantage which would not average out across the population.
quote: The dynamic equilibrium does not require that "ALL mutations that get in, get out" or even all deleterious mutations. As I have said, in this case deleterious mutations are held at a fixed level. It is only the number of deleterious mutations that matter. The fate of individual mutations - whether lost immediately or remaining in the population indefinitely is irrelevant. Therefore 100% efficiency (which would be the immediate removal of all deleterious mutations) is not required.
quote: Unfortunately for your argument the balance also includes mutations lost by genetic drift. As the number of deleterious mutations goes up, the number of deleterious mutations lost through drift also goes up. And as I state above the balance is not about the fate of individual mutations, it does not require that we remove all mutations, only that the numbers (etc) remain roughly constant.

quote: Your argument that all function was lost is not logically valid. That the measured function was lost is not disputed. I don't know why we keep having to go around and around on this point with you continually shifting your position when you aren't even making anything of the point.
quote: Given that I wrote D rather than D and given that my statement is correct if I meant D and not D it seems clear that I meant D and not D.
quote: I am afraid that you are misreading it. It says that D may be used to represent (D, *), not D*. I can see the sentence that you mean, but the following sentence makes it clear:
It will be clear from the context whether D signifies the full pattern (D, *) or merely it's first component.
quote: Again you misread it. Just as there are two Ds, there are two Es. The correspondence maps D to E (p144). And the result of applying * to D is D*. NOT E unless E=D*. And in this case the problem is that the E you want to use is NOT D*.
quote: The specification is "bidirectional rotary motor-driven propeller". There are many things that are "bidirectional rotary motor-driven propellers" that are not E Coli flagella. Got it ?
quote: You are making no sense. We don't need an improbability inflated by unspecified details. Why would we ?
quote: It's not obvious to me. In fact it is obvious to me that Dembski s right on this point and that the probability of D* is the only one that matters. Unspecified information is irrelevant to identifying design - and anything outside of D* is outside of the specification D.
quote: Here's that quote again (TDI p165)
...the event that needs to have small probability to eliminate chance is not E, but D*.
Since D* includes BOTH the flagella (and more) you would need to combine their probabilities to get to D*. (And if you find ONE with less than 400 bits of information, the probability of D* will not be low enough so there is no need to continue).
quote: Every time you write by "your logic" you mean some crazy idea that you have. Can you please stop doing that. And, in fact, the position you are disagreeing with is Dembski's.
quote: Here's that quote again (TDI p165)
...the event that needs to have small probability to eliminate chance is not E, but D*.
So THAT is the probability we want to compare to the UPB.
quote: Which is one of the reasons why simple patterns are better. They are easy to detach from the observed event.
quote: Unfortunately you did indeed claim that nearly all beneficial mutations increased genetic entropy, and offered sickle-cell as your first piece of evidence.
quote: You are simply wrong about genetic entropy. Genetic entropy is abut reproductive fitness, not some poorly-defined and unquantifiable concept of "genetic information".
quote: What I am telling you is that the point you were meant to be supporting was your assertion that the population needed to be infinite for the statistical effects of a large population to significantly reduce the impact of "noise". That has nothing to do with your ideas about "genetic information".
quote: That is simply your opinion. The experts working in the field don't seem to agree. Which is why you never found a paper that actually supported your claim.
quote: And in large populations - as I keep pointing out - the effects of noise will be reduced. That is why genetic drift - your "noise" - is weaker in larger populations. That is why I don't need to appeal to correlations - and it would be to your advantage if you could.
quote: Of course I have already pointed out a case where the removal through selection is not 100% efficient and where not all deleterious mutations need be removed - and yet they do not accumulate. A dynamic equilibrium where the NUMBER of deleterious mutations removed from the population - by either selection or drift - equals the NUMBER of deleterious mutations added to the population. It is not necessary that all be removed, nor is it necessary that selection should do all the work of removal when drift can also assist.

quote: In fact we know that you didn't mean that. But we can agree that the only functin actually tested for was lost.
quote: D is not used as an abbreviation for D*. It is used as an abbreviation for (D,*). They are not the same thing.
quote: As you can clearly see the pattern is (D,*). D is a description (not an event). D* is the event described. And D is sometimes used as a shorthand for (D,*) - but never for D*.
quote: You only have to look at it to see that that is wrong. It is D* (with no bolding). Therefore * is being applied to the description D.
quote: It makes perfect sense, and I already explained why. If we use the specification "more heads than tails" for a given run of coin tosses we want the probability of getting any of the sequences that fit that specification. We don't want the probability of that particular sequence. As Dembski says (yes, it's p165 again !)
...the event that needs to have small probability to eliminate chance is not E, but D*.
quote: The target event is D* (that is the whole point of the specification - to define the target). So if we want to calculate the probability of hitting the target we want the probability of D*. And that is what we need to infer design: As Dembski says (TDI p165)
...the event that needs to have small probability to eliminate chance is not E, but D*.
quote: S(T) is available specificational resources. p(T|H) would be the probability of meeting the specification (i.e. p(D*|H)). Here's what it says about T (p18)
[qs]
...T in [b]P(T|H) is treated as an event (i.e., the event identified by the pattern).
[/qs] quote: Wrong again. On the basis of this specification, neither would be CSI since there are less than 300 bits of specified information.
quote:Yes, I do know. It is supposedly a probability set so low that we cannot expect a single specified event of this probability to occur in the lifetime of the universe. Unspecified events - and more importantly sequences of events = of arbitrarily low probability can and will occur. That is why Dembski says (TDI p165):
...the event that needs to have small probability to eliminate chance is not E, but D*.
quote: And of course your argument was completely wrong. How can increases in fitness fail to offset decreases in fitness ? Genetic entropy is about reducing fitness, beneficial mutations increase fitness.
quote: If you really listened to them you would know that they didn't agree with you. Firstly Kondrashov say that (effective) population size is important. That is what Ne is. Secondly Kondrashov does not say anything about beneficial mutations contributing to genetic entropy. He is (correctly) talking about the accumulation of mildly deleterious mutations. Here are the first three sentences of the abstract - omitted from your quote - which make it clear:
It is well known that whens,the selection coefficient against a deleterious mutation, is below ≈ 1/4Ne, where Ne is the effective population size, the expected frequency of this mutation is ≈ 0.5, if forward and backward mutation rates are similar. Thus, if the genome size, G ,in nucleotides substantially exceeds the Ne of the whole species, there is a dangerous range of selection coefficients, 1/G< s/E2>< 1/4Ne. Mutations within this range are neutral enough to accumulate almost freely, but are still deleterious enough to make an impact at the level of the whole genome.
The only point regarding beneficial mutations is that they are not sufficient to offset the problem. So no, the professional clearly doesn't agree with you.
quote: In other words you think that your interpretation of an analogy dictates Sanford's meaning ?You're going to need to do better than that if you want to claim that Sanford is talking about anything other than the same accumulation of deleterious mutations that the Kondrashov paper refers to. None of your other quotes offer any support for your position either. In fact it seems like you are actually avoiding any quote that would clearly state what Sanford means. quote: Of course the issue here is not chance "making things worse" the question here is whether the "noise" interfering with selection tends to even out over large numbers. The first sentence of the Kondrashov abstract referred to above clearly indicates the importance of population size in controlling deleterious mutations. Listen to the professionals. They agree with me, you know. So your argument makes no sense and the conclusion is contradicted by a reference you yourself put forward.
quote: That paper contradicts you. It explicitly points out the importance of population size. Your only quote relating to infinite populations only states that there is a balance point that can be more easily calculated given an infinite population,.
quote: That is just assertion. Remember to listen to the professionals. They agree with me, you know.
quote: No, you haven't. In fact you said that you didn't need the numbers, And you were wrong.

quote: If I have to read your mind to understand your posts there is no point in you posting anything.The fact is that you have explicitly argued for the claim that ALL function was lost, not just the known function and from that we can conclude that that is really what you meant. quote: "bidirectional rotary motor-driven propeller is just plain D. And neither it. not D*, nor (D,*) equal 10^20 which is the estimate of the specificational resources given a four-part concept.
quote: When I refer to the description, D, I do not mean the descriptive language D or the pattern (D,*). So the answer is that I mean neither.
quote: I do not take the number of throws as the complexity of the event. And in fact it doesn't have much effect on the probability unless the number of throws is both even and low (the probability is 0.5 for any odd number of throws and the lowest probability is 0.25 for 2 throws - a difference of 1 bit in the extreme case). What is more the number of proteins in the flagellum is NOT a number of attempts. It is an unspecified detail of that particular "bidirectional rotary motor-driven propeller, just as the exact sequence of heads and tails is an unspecified detail in my coin-toss example.
quote: I thought that the specification was "bidirectional rotary motor-driven propeller. There is no mention of 50 proteins there. D* - the specification considered as an event would be something like "getting a bidirectional rotary motor-driven propeller.Either you are using some other specification you haven't mentioned (and one that smells of fabrication) or that isn't D*. Which is it ? quote: So then we need to calculate the probability of D*. Which means that either you need a valid specification for the calculation you want to use, or you need to do the calculation for the specification we agreed - "bidirectional rotary motor-driven propeller. Whichever you prefer.
quote: It's the specificational resources, no matter what else Dembski or you call it.
quote: The pattern is not the specificational resources and the description is not the pattern - and it isn't the specificational resources either.
quote: No, it wouldn't for reasons we've already gone into.
quote: Wrong, you need 400 bits of SPECIFIED information to be CSI. Unspecified events aren't CSI no matter how many bits of "complexity" they have.
quote: To give the simple answer. You find a valid specification that includes the event. You calculate the probability of meeting the specification. If that probability is less than the UPB (2^-400) then you infer design.
quote: Of course we are talking about reproductive fitness. And since genetic entropy is about reproductive fitness and not some vague notion of "genetic information" fitness gains from beneficial mutations can and do counteract the fitness loss of deleterious mutations. Just how hard is that to understand ?
quote: 1) What am I supposedly wrong about ? 2) I am glad that you admit the importance of size, however you still have to deal with the fact that the experts do not think that genetic entropy is a problem for large populations. (All your quotes from experts deal with small populations) 3) Kondrashov does not say that beneficial mutations play no role, simply that they are not sufficient to deal with the problem, given the numbers he is using for effective population size and mutation rate etc.
quote: My point was that beneficial mutations did play a role, and that your argument ignored that. Kondrashov does not deny that.
quote: Actually you didn't because not one of your quotes mentioned "genetic entropy" at all. They were just the old creationist "information loss" argument (which is best described as meaningless). The point is that "loss of information" without loss of fitness is not going to force a species into extinction. "Loss of information" with a gain of fitness is more likely to save a species from extinction.
quote: Because it explicitly states that the risk of extinction comes from the effect of fragmentation lowering the effective population size.
Here we show that metapopulation structure, habitat loss or fragmentation, and environmental stochasticity can be expected to greatly accelerate the accumulation of mildly deleterious mutations, lowering the genetic effective size to such a degree that even large metapopulations may be at risk of extinction.
It does NOT say that equilibrium can only be achieved with infinite population size, only that the equilibrium level is independent of the mutational effect with infinite populations size. And in fact they do calculate this equilibrium level in their work.(Text for figure 3)
Simulations of populations with mutation accumulation (open symbols) start with the mutational load of an infinite population at mutation-selection balance
quote: Or they are in equilibrium with a finite population. You haven't offered anything to rule that out yet.
quote: No, I didn't miss that. But it doesn't show anything because it begs the question. It simply assumes that less than 100% effectiveness equals accumulation (which is what it is supposed to show). However, even delayed (but certain) removal is less than 100% effectiveness, and you also need to count the loss of deleterious mutations due to drift. As I said, to deal with the issue you need real numbers, because they control the equilibrium level.

quote: So much for letting it drop ! Anyway, thanks for admitting that I was right about what you said , and that I did NOT need to read your mind.
quote: Just because Dembski uses D sometimes to mean the D component of (D,*) and sometimes to mean (D.*) does not mean that they are the same thing. So, no, D does not equal (D,*). "bidirectional rotary motor-driven propeller is just D, not (D,*). And neither is equal to 10^20
quote: Yes there is - it's the D in the pattern "(D,*)".
quote: Do I need to remind you that we want the probability of D*, not the probability of the unspecified event ? Do I need to point out that this example proves exactly that ? Do I need to repeat that the probability of meeting the specification I gave - P(D*) - is at least 0.25 regardless of the number of throws ?
quote: Since we're talking about the details which AREN'T part of the pattern, they can't match it.
quote: OK, then 50 proteins are NOT part of D*. D* is "getting a bidirectional rotary motor-driven propeller - no mention of 50 proteins there. Whether it is mentioned in NFL doesn't matter if it isn't mentioned in the specification.
quote: That doesn't even make sense. 10^20 considered as an event is 10^2954 ?
quote: Dembski also says that it's the specificational resources.
quote: But the combining is to eliminate the unspecified information. So if you agree that we shouldn't count it then you have to agree with the combining.
quote: We don't want the probability of the event, just the probability of meeting the specification. And in the case of the flagellum I have no idea of how to calculate it. And neither does Dembski.
quote: In that case can you quote him actually saying that ? Because you didn't.
quote: And it says that it is only a problem when fragmentation REDUCES the effective population.Therefore it doesn't support you. quote: If you were agreeing with me all along, then why were you arguing ?
quote: They do have to mention it if they are saying that this information loss IS genetic entropy.Which is the point you were supposedly trying to argue. quote: Which only covers "losses of information" that negatively impact fitness. Not those that increase fitness.
quote: It does contradict you because it makes it clear that the problem only exists for low effective populations sizes.
quote: By selection and drift removing deleterious mutations from the population at the same rate as they arrive. Thus we have an equilibrium without selection being 100% effective.
quote: Wrong. The more deleterious mutations in the population the faster drift will remove them. That is one of the factors that your "example" didn't take into account.

quote: You indicated that the only important thing was the known function - which we agree occurred. All I did was make it clear that you earlier had argued for loss of ALL function. And you turn around and start trying to argue for the loss of ALL function again.
quote: It's the description D, not the pattern (D,*). And the "complexity" is just the specificational resources. It certainly ISN'T the probability of D*, which is what we want.
quote: If you are referring only to the completely irrelevant unspecified complexity, then yes. But that only supports my point - we do not want nor care about that complexity. It is only the specified complexity which is never less than 0.25 for the specification - which is why that specification can never indicate design.
quote: The 50 proteins and their structure in the case of the flagellum. Probably some details of their arrangement, too. For my example with the coins the exact sequence - which is what your "complexity" above refers to.
quote: In other words Dembski didn't completely botch the calculation in NFL - because Dembski says so. Unfortunately for you he did botch it. The calculation in NFL is NOT the probability of getting a "bidirectional rotary motor-driven propellor" or even close as should be quite obvious. The fact that it uses details which clearly aren't in the specification is a dead giveaway.
quote: It's quite simple. if we want p(D*) we want the probability of getting ANYTHING which satisfies the description D. So we combine the probabilities of everything which satisfies D.So either you agree to the combining, or you disagree that we want the probability of D*. quote: The probability of matching the pattern - which is what Dembski's method uses to infer design - is the probability of D*. As Dembski says - TDI p165
..the event that needs to have a small probability to eliminate chance is not E, but D*
So you're just laughing at Dembski
quote: But only if the noise is increasing. So THAT "noise" is not genetic drift. Do pay attention to the context.
quote: No, it doesn't always happen. Populations can increase in size. They don't have to get fragmented to the extent that mutational load is a problem.
quote: Yes. I see that you are now agreeing with me that beneficial mutations DO help and that you were wrong to leave them out of your diagram. Perhaps instead of trying to cover up your mistakes you should try harder to avoid making them in the first place ?
quote:With a LOW effective population size. Which is exactly the point I made. quote: So what you are saying is that less than 100% effectiveness is by definition 100% effective.I don't think that makes much sense. It's quite clear that not all deleterious mutations are removed, and not all of those that are removed are removed by selection, so selection is obviously less than 100% effective. quote: With a large population size and genetic mixing from sexual reproduction there will be selection for and against individual alleles. Only in the case of pure clonal reproduction would it make sense to say that the whole genome was the unit of selection. Because without that the whole genome doesn't survive. It is just a feature of one individual.
quote: But I am not saying that drift is better than selection. I am saying that drift AND selection both remove deleterious mutations. Obviously together they will remove more than selection alone ! Edited by PaulK, : No reason given.

quote: And an unknown number plus one minus one plus an unknown number is an unknown number.
quote: I only agree that the number 10^20 is Dembski's estimate of the specificational resources.
quote: No, I don't agree because the "complexity" is produced from a probability calculation and we don't know what the results of the two calculations would be. It is likely that the one needing more proteins would be less probable, but it isn't certain.
quote: He didn't calculate the correct probability. Or even anything resembling the correct probability. That's what he did wrong.
quote: But do you understand that since both wil fit the pattern we need the probability of getting either of them ? Or any other flagellum.
quote: The "noise" in the quote is not the "noise" of genetic drift that we were talking about earlier.
quote: Except that you DIDN'T allow them to offset the fitness loss. Which they do.
quote: It helps me because it shows that the article agrees exactly with what I said. Mutational load is only a problem with a low effective population size.
quote: You obviously don't know much about reproductive biology. Sexually reproducing species get only HALF the genome of each parent.
quote: Of course, since you have no sensible measure of "genetic information" any such statement is pure speculation.

quote: You also specifically said all functions and argued that we could infer the loss of all function from the loss of the known function.
quote: I's the specificational resources which Dembski also for some reason calls the complexity of the pattern. The point of calling it the specificational resources is because it is a more meaningful name so you won't confuse it with anything relevant to the probability of matching the specification (the probability of D*).
quote: The logic was explained. THe two cases are simply not comparable - not least because in the case of the dice we know how to calculate the probability. We don't for the two hypothetical flagella and there could be aspects which make the one with 1,000,000 proteins more likely than the one with 50 (which would depend on things like the proteins).
quote: It doesn't use a valid specification and it ignores relevant information.
quote: It may not matter to you what the material you quote actually says, but it does to anyone honestly interested in understanding the issues. This other noise IS the "genetic entropy".
quote:Congratulations on finding one paper that actually supports your point - to a degree. A definite step up on using papers that contradict your claims. Of course it is purely theoretical - and published in a physics journal - and still presented only as a possibility depending on the parameters. It is still not the inevitability that you claim. quote: Did you not read that it is specifically dealing with the problems faced by a fragmented population ? Did you not read that it says that fragmentation lowers the effective population size ? Do you not understand that it is effective population size that matters ?
quote: So you didn't mean what you said and what you did mean was a complete irrelevance. (Here's a hint random mixing of the parental genomes supports my point)
quote: Of course I never made reference to single nucleotides (or do you not know about genes or chromosomes ?) The fact is that in a typical sexually reproducing species the whole genome will appear in very few individuals, and so it will not have much of an opportunity to be selected. It would take an extreme case to have much impact. However, genes are usually passed on intact (and genes on the same chromosome have a tendency to stick together). So genes are better as a unit of selection because they can spread more widely in the population and persist over the generations.
quote: CSI is a binary measure (either something is CSI or it isn't) which makes it a poor choice. And it can't be measured for any gene which makes it a totally useless choice.
quote: Since Dembski's "complexity" is a probability measure which does not depend purely on length anyone who claims that any flagellum based on 1,00,000 proteins MUST be more complex than any flagellum based on 50 doesn't know what they are talking about. ANd Shannon information isn't even relevant to that.

quote: Which is what I said. And it's wrong - and you know it's wrong.
quote: Of course that isn't true. You can't work out the probabilities just from the number of proteins.
quote: I'm not inventing anything. I'm just pointing out that there can be factors that you simply haven't taken into account.
quote: Obviously you don't know what you are talking about. We aren't talking about the design of search algorithms, we are talking about calculating the actual probabilities.
quote: It seems clear enough. Dembski's method requires the calculation of the probability of meeting the specification (the probability of D*). Dembski didn't do that. What more is there to say ?
quote: Since the "noise" IS the "genetic entropy" it can''t be a cause of it. This is what happens when you don't care about understanding the material you are quoting.
quote: Well no. I've never argued that it couldn't under some theoretical conditions be a problem for a large effective population. If you're prepared to accept that it might possibly, in theory, be a problem for some large populations - and no more, then we can close this down.
quote: Well, no. Usually the material you quote DOESN'T support you. But really you are missing the whole point of the paper. It 's arguing that conservationists need to try to avoid letting a population fragment because that can significantly increase the risk of extinction. If extinction was inevitable anyway, and the fragmentation of the metapopulation was not relevant there wouldn't be any point in the paper at all.
quote: Both "reasons" are completely bogus and have nothing to do with my argument. I suggest that you go back and read it again since you obviously didn't understand it..
quote: As I have pointed out, this is incorrect. Using the genome as the unit as selection is simply silly for the reasons I have already given.
quote: Strictly speaking, you can't. As I said CSI is binary - either something is CSI or it isn't. You can have bits of information or even specified information but not CSI, because the C is the probability bound. Anything over the bound is Complex, anything under it is not. And that's all there is to it.
quote: Of course it can't be done and it hasn't been done. That's why you can't come up with a valid example.

quote: No, it must merely be possible that there are unknown functions. Since that *is* possible it is not valid to infer that loss of the one function tested for is loss of all function in every case.
quote: No, it isn't like that at all. We know how to do the calculation for dice. We don't know how to do the calculation for completely unspecified proteins - because it can't be done without more information.
quote: I was thinking more of evolutionary relationships between the proteins - with each other and with other proteins in the organism or that might be acquired by the organism - and the lengths of the proteins. 1,000,000 slightly different proteins might be more probable than 50 hugely long proteins, all completely unrelated to each other and anything else . I could probably think of more factors if you actually bothered to show the calculations.
quote: And in the example we are considering, which algorithms would they be ?
quote: In other words you take the article as support for your position that we shouldn't bother trying to do things right, we should just do them your way. Unfortunately he is talking about the performance of search algorithms, not the calculation of probabilities in a specific case.
quote: A completely bogus and irrelevant calculation.
quote:In other words by giving a quote which doesn't include the word "noise" you think that you can show that a different quote didn't use the word "noise" to describe genetic entropy. quote: No, that isn't obvious at all. Theoretical models aren't reality.
quote: But it doesn't inevitably destroy even small populations. The cheetah population has suffered from a severe genetic bottleneck (at one point probably reduced to a single pregnant female). And subsequent hunting has made their problems worse. But they're still around.
quote: Would you like to explain the relevance of a fragmented metapopulation in the article if it does NOT make a species more vulnerable to mutational meltdown ?
quote: The fact that they dont address what I'm saying at all.
quote: It's also not what I said. What I said is that the gene is a better choice for the "unit of selection" than the genome. And I gave reasons. Now if you want crazy we can take your assumption that the unit of selection must either be the whole genome or individual nucleotides. Anybody who knows about genes would know that that was wrong.
quote: No, they are not bits of CSI, because CSI is having more bits than the threshold. That's what the "Complex" refers to (I know it's misleading but that's Dembski for you).
quote: Because your "valid examples" obviously aren't.

quote: That's obviously false for a start.
quote: I'm not making up anything. I'm just keeping it to what we DO know about. The known function, the one tested for was lost. Unknown functions - whether existing before or gained as a result of the mutation - were not tested for and obviously could occur in some cases even if they did not appear in this particular set of experiments. So we don't know anything about those other than that they could be present.
quote: The 50 proteins in the E coli flagellum are all distinct. And if the proteins WERE identical there would likely be very little difference in "complexity". (It would be more like all the dice being dice rather than all the dice coming up with a particular number !)
quote: Since you don't actually use evolution in any of your calculations - no, it isn't obvious.
quote: So, according to you, Dembski makes this assumption because the argument needs it. That's not a good reason. And his real reason (he's attempting to provide an estimate of *general* performance with limited information) makes it inapplicable to a situation where we need the real numbers for a specific case.
quote: I already did.
quote: I'm afraid that is another silly argument, since the English language allows for more than one way to describe a thing. In fact deleterious mutations could easily be described as "noise" in the genome. So merely NOT using the word "noise" in the definition does NOT mean that "noise" can't be used to refer to genetic entropy.
quote: Because you only have models that state that large populations can, under some conditions, die out from mutational meltdown. Those models can't tell you if those conditions apply to any real populations.
quote: Of course the relevant measure is not any "absolute" measure of information. A non-viable embryo cheetah, doomed through mutational meltdown, would still have far more "genetic information" than the single RNA strand. And it wouldn't make the slightest difference.
quote: I'm not an expert on RNA life, but there's no clear barrier against increases in functionality. In reality, genetic entropy doesn't even stop increases in functionality occurring and being selected.
quote: Since you couldn't be bothered to read it the first time, or go back and read it when I asked you to why exactly should I repeat it again ? If you really ant to read it just go back through the chain of posts.
quote: I already explained. You responded by asserting that I must be assuming that the nucleotide was the unit of selection and that I must be ignoring the random mixing of genes. Neither of which was true at all.
quote: Of course, you are exaggerating here. While idealisations make for an easier mathematical treatment, none of these have to be absolute.
quote: What I said. CSI is not measured in bits. Information and Specified Information is measured in bits. Complex Specified Information is any Specified Information with more bits than the bound (or has a probability below the bound - which is the same thing).
quote: In fact I keep explaining why. Your calculations keep trying to pull in irrelevant details which aren't part of the specification. That's obviously invalid.
