Clouds weren't designed. You have once again moved the goal posts.  WE are talking about things designed.

And Reverse Osmosis water purifiers are far more complex than water stills.  Both are designed.  Both are irreducibly complex.  Design has the capability of and often does dramatically increase complexity and information content (countless terabytes is now common) in designed systems of lasting utility.  There are zero examples of material processes doing the same beyond the capability of what blind search is capable of accomplishing (which is less than 500 bits of information).

This is the fundamental problem with your evolutionary narrative.  You have not shown how any materialistic process can or does accomplish what you claim for evolution.  Then when we observe evolutionary processes in action it confirms this problem.  Every observed example of evolution falls well below the 500 bit limit.  Observations confirm that evolution does not proceed fast enough and lacks the required processes that would enable it to generate new biological information to build new form and function.  Can you offer even one example of a materialistic process generating more than 500 bits of information?  NO.  Yet the presumed evolution of ape to man requires on the order of 300-600 megabytes of new information.  Design is quite capable of accomplishing this kind of change.  Direct observation of evolutionary processes strongly suggests that evolution is not, and the hard sciences of information theory chemistry and probability tells us why.

Repeat it enough and it becomes true, eh?

RF, we understand your zealous point, we disagree as does the science community.  Stop trying to convince yourself and us, do some research and convince them.

Its becoming absurd with RF.  Again he changes the topic just to get back to his mantra (Argument from Incredulity, Argument from Ignorance).

RF, you asked if something designed ever got less complex, not if it could or couldn't be designed, or whatever you are babbling about.

I think we can safely say that Specified Complexity is one of the hallmarks of ID.  Complexity is an idea in Information Theory, but SC is specific to ID.

Complexity can be measured, it has a formula and tells us a little bit about the amount of information in something.  It is an objective measure, and therefore tells us nothing of the information of, say, a sentence like "Methinks its a weasel". It can only tell you the odds of those particular letters coming up and how much information is in the sentence based on the odds of those characters.

In other words, "oahofwfu hos o asfaho" has equal information.

Not according to ID.  ID calls the first one SPECIFICALLY complex and then makes the jump to DNA and says it is a coded language that means something.


So, here is the challenge to any ID follower:  How much specified information is in DNA?  Not information (as according to Shannon) but the SC variety?

Since there whole "possibilty theory" rests on the specified information in things, we have a right to ask.




Just so people don't think I'm making this up, this is the definition from the ID'iot's at ISCID:

Quote
Shannon information is the type of information developed by Claude Shannon and Warren Weaver in the 1940s. Shannon information is concerned with quantifying information (usually in terms of number of bits) to keep track of alphanumeric chcaracters as they are communicated sequentially from a source to a receiver. The amount of Shannon information contained in a string of characters is inversely related to the probability of the occurrence of the string. Unlike specified complexity, Shannon information is solely concerned with the improbability or complexity of a string of characters rather than its patterning or significance.
http://www.iscid.org/encyclopedia/Shannon_Information



So, how much SC is in DNA?  I want an objective number.

Does this 500 bit limit come from Dembski's Universal Probability Bound? If so, is this concept accepted by even a significant minority of statisticians? It seems to me that assigning a bit value to the genetic code and assessing information increases bases on coding for new proteins ignores the real world model. I'm not sure small changes in certain genes, particularly regulatory ones, wouldn't result in larger changes in the complexity of the phenotype which could be considered a whole other level of increased information. There is the whole other matter of potentiality, where there is a possible selective advantage to holding on to related non-fuctional genes rather than dumping them in a generation or two. How do you calculate those odds? But even at the limited level Dembski is referring to Tom Scneider thinks Dembski is full of it. Mutation and selection seem to be enough, letting alone adding the interplay of other major players like genetic drift.

Where'd this come from? Does this include modifications of existing genetic information? I like to think we're at the pinnacle of creation, too, but evidently the world has other ideas. Last I looked there wasn't a large difference in the size of our genome and the other apes. If size matters, the most complex creature that we know of is the trumpet lily. There are rats with twice the genome we have. That's kind of depressing.

Another problem is that Information (in the Shannon sense) is not the same as what Dembski calls Specified Information (or SC).  Demsbki has not come up with a way to measure the subjective determination of "its looks designed".

In cryptography the National Research Council has set 10^94 as the Universal Probability Bound to secure encryption schemes against random search attacks. For more information see, Kenneth Dam and Herbert Lin in "Cryptography's Role in Securing the Information Society", Washington National Press, 1996.

Unless there is some mechanism shown to retain them we would go with observed mutation rates in non-functional sequences.

In experimentation and actual observation mutation and selection falls far short of "enough".  We observe that it occurs far to slowly and accomplishes far too little.

Then it seems like a stretch to apply it to DNA. You can set the parameters to calculate the probabilities involved in a decrytion search. You can't do the same thing with DNA. In a changing environment the potential functional target sequence is always unknown and you are already starting with a functional chemical code and you are not starting from scratch. There are too many complexities and unknowns to compare it to a brute force find and replace algorithm. I don't think the cryptographers see their Universal Probability Bound as applying to biological systems and I can't find any biologists that think it does, either.

Encoded is not the right word. How about self organized? It isn't all that deterministic either, considering the hit or miss transfer mechanism and the error prone copying system. Pretty sloppy for a code. Here is a quote by John Wilkins in the comment section of Shallits blog:

Jeff, I'm going to disagree with you on one point - DNA has no "information content as such. Our sequencing of DNA has information content because we can apply information metrics to it, but DNA itself is just a molecule that plays a particular crucial chemical role of catalysis in cells.

This is the distinction, if you like, between a UTM and a physical computer. You can't run a computer forever to see if a particular algorithm will halt. At best you can simulate it. UTMs are not physical things, and don't break down.

Likewise, DNA is not a sequence of symbols - it's a physical entity with structural as well as sequential properties, and our analyses of information content are just tools that may, or may not, give us abstract understanding of some of its properties in a given organism and environment.


Here's Shallit Himself:

Of course, Pearcey and Thaxton aren't really interested in the information content of sentences or leaf piles. Their goal is to demonstrate that life is too complex to have evolved through natural means. But since high information content can result from random events -- for example, mutation -- it is not surprising at all that DNA can be viewed as a string with high Kolmogorov information. In fact, as Greg Chaitin has observed, pretty much the only way to get large amounts of information in the mathematical sense is to either do a really long calculation, or to exploit a source of randomness. DNA's high information content is prima facie evidence it resulted, in part, from an essentially random process.

"We" (by "we" I mean them there scientists) do and we've been through this before. There was the duplication (an increase in information itself) and frame shift (with accompanying retention of original function) that led the functionally new nylase enzyme. If that's not enough there are 3.5 billion years worth of life forms encased in rock staring you right in the face. Are we to believe that each sequence of trilobites, or proto-therapods, or hominids, or cetaceans was tweaked at precisely the right time to mimic an evolutionary progression? What about the 99% extinction rate for species? Speaking as a life form on this planet, I got to say that is some pretty poor planning.

Thanks. I was hoping I could. But that doesn't begin to address my point. Your statement implied that humans show a greater degree of complexity than the other apes. Is that what you meant to say? Does information in the genome have a one to one correspondence with expressed complexity? Do inactive genes mutated to form some new function count retroactively as complex specified information? Somebody needs to pull a piss test on this designer. He's been showing up to work drunk and getting things all snarled up. Nothing makes sense. How come a freaking flower gets 30 times as many base pairs in its genome than us, the spitting image of the Big D himself?

You can't find when you don't look.  It is not a stretch at all to apply the methods of probability to genetic studies.  Nearly ever evaluation in genetic and protein source research included concepts from probability.  Just like in cryptography and other probability studies, there are ways to manage uncertainties to get meaningful results.  protein function is far more closely related to shape and chemic affinities than to changing environments and one can evaluate the potential ratio of workable protein combinations based on these characteristics.  When one does this they find the entire range of potentially workable proteins and not just the ones that may be suitable for the more limited environmental conditions you describe.  Even here the ratio of workable to unworkable proteins is in the order of 10^-70 and higher.

The error rate is less than 1 in 100,000,000 duplications and except for in the case of reproduction, the feedback redundancy and repair mechanisms drop that rate to very close to zero.  This is far fewer errors than human language.  It is far fewer failures than computer systems which have failure rates in the low millions.  Your quotes seem like prior commitments from people who are looking to explain the realities away.

The modest mutation rates seem like a clever way to introduce minor variation in non-critical systems to achieve a degree of differences from one individual to the next.  It clearly is quite proficient at this task.

This is not an example of a regulatory gene alteration.  You have not provided the evidence that shows that original function was retained (I asked for it twice, still nothing).  It fit well within the range of probabilities for single point mutations and it involved a single protein enzyme with no binding sites and no required interaction to other protein systems. 

This is an example of the kinds of things evolution can do and it fits well within the range of observed evolutionary processes which we have seen can accomplish one and two step processes (if you ever produce the data, this would be one of a few known two step processes) but we don't have even one example of a four step evolutionary pathway.  We have had an opportunity to observe 10^30 organisms in the 50 years of genetic studies by now and we still don't know of one four step evolutionary pathway.  In the mammalian line there are estimated to be fewer than 10^18 total organisms ever to have existed and yet the number of required evolutionary steps number in the billions and billions.  In the lab, the observed rates are coming in billions and billions and billions and billions of times too slowly to account for the diversity we observe.

No, more complexity overall in that it is different and unique.

Sure. but the odds of generating useful proteins from random non-expressed areas of the genome is astronomical given that the ratio of useful to useless proteins is 10^-70 or so as indicated by Axe in 2003.  It is the reality of these kinds of numbers that explain why evolutionary processes are quite proficient at the occasional point changes and two step processes but cannot accomplish the 10-20 step processes required to generate a useful new protein in a reasonable period of time.  HIV and other retroviruses even with huge mutation rates and fast replication rates would need billions and billions of years just to produce one new protein from a non-expressed area.

This one was funny.  One of the biggest reasons "god" is the most prolific abortionist is because of mutations in the genes.  But I guess when you think the soul is the only thing critical, I suppose everything else is non-critical - even life itself.
