The fact that an IC system was shown to evolve removes the use of IC as an argument that they can not evolve by Darwinian evolution. It only takes one counter example. It is done, finished, caput and a very dead parrot. OK... I want you to show me where Behe states that an IC system can't evolve. The very fact (THAT CERTAIN) IC systems could evolve from its intended design tells me that it is even more IC than I thought it was. It has the miraculous capacity to adapt. I wrote (that certain) is because in this case, the bacteria was arguably presented with the challenge of hydrolyzing lactose. You might say that it had to adapt or die. The flagellum serves its purpose and doesn't have any forseeable challenges that it must adapt too. Therefore, it doesn't have to change. I can also state that none of my arguments have been arguments from perfection for reasons why I won't go to in this particular thread. Do you understand me?

We have complete storage systems that know what has to be there. Not because it has it's own intelligence but, because that's they way they were programmed. When you turn on your computer, how does it know what to do? Yes...very good. Sometimes I feel alone or outnumbered in these debates. I just thought I would give you some support. One of the many functions of so-called junk DNA is to mark genetic sites for programmed rearrangements of genetic material. ("The Role of Translocation and Selection" by Green)

You see, ID can explain everything. When the Darwinists come along and cry foul, they tell us that Darwinism explained many things with natural processes.
It is called the "Darwin of the Gaps" argument. Then along comes ID again and explains how and where Darwinism had it wrong. Such was the case in the so-called junk DNA. Once ID explained it, the Darwinists had to fall back and another one of their gaps was proven simply not to be true. At the same time their gaps continue to become bigger and our gaps become smaller. Sound familiar? Ha Ha Ha... Just kidding for the most part. But you can see how their argument was put into a form that brainwashes. Edited by traderdrew, : Just adding more "Intelligently Designed Complex Specified Information"

Wow, you're either missing the point entirely or moving the goal posts out of the stadium, down the street, and into another city. Argument: Organisms have IC functions. IC can't evolve because only part of an IC system is useless and wouldn't be selected for. Counter-argument: We have shown an IC system, removed one part to make it not work, and shown a new, albeit similar, one evolve thus proving that an IC system can evolve. Traderdrew's rebuttal: This just shows IC even more, adaptation itself is IC, and thus evolution is IC, therefore evolution disproves evolution.

Thanks Phagey. Smart aye? Intelligent design? There no doubt exist natural laws, but once this fine reason of ours was corrupted, it corrupted everything. blz paskal

Totally missed the point, it does not even relate to the topic at all.

Translocation and transcription are inherited intelligence. There is nothing this lot can do to prove otherwise.God's work is all around us.

Hmm, who are you replying to here? Yourself? Anyway, If ID explains so many things, perhaps you could say what it does to another thread because it would be off topic here. Maybe you could start by this thread: EvC Forum: What exactly is ID?.
I know It's a thread that I've created but after many weeks without answers, I would like to have this basic question answered...

Hi Phage0070, I have trouble with your position, as it is not supported by the definition Behe gave when he first defined IC.
A system which was thought to be irreducibly complex had an element removed, and it did not cease functioning but rather mutated into a working arrangement. Thus, it was proven not to be irreducibly complex. It did stop functioning. Generations of e.coli lived and died without metabolizing lactose. The mutations did not repair the old system but developed a new system, with parts that did not exist before, and the method of metabolizing lactose is different from the previous method. From the previous link on Ken Miller's website:
quote: These changes\alterations\mutations are not repairs, but novel to the bacteria in the experiment.

Trader writes: It is called the "Darwin of the Gaps" argument. Then along comes ID again and explains how and where Darwinism had it wrong. Such was the case in the so-called junk DNA. It was practicing professional biological scientists not IDers and creationists who refined the definition of what "junk" DNA actually was. The term "junk" DNA was collequiel term coined by a Japanese scientist in 1972 to describe portions of the genome which are not used to translate proteins. However even before this term was coined scientists suspected that some portions (though not all, some of it really is "junk" in that is left-over remnants of viral and other evolutionary mutations of the genome which are now useless) of the genome called "junk", which at one time was once unknown and mysterious in its purpose and function, had other functions besides protein translation. It was these same scientists themselves (not the creationists and IDers) using the scientific method who continued to correct this misunderstanding (or more accurately gap in knowledge) and revise these theories about what different portions of the genome actually do. This is the problem with creationists and IDers. Instead of conducting there own scientific experiments, research, analysis, etc to explain natural phenomena; they capitilize on, misconstrue, distort, quote mine and flat out lie about the research conducted by hard work scientists who are putting thousands of hours into conducting real science using the tried and true scientific method.
Trader writes: Once ID explained it.. Bullshit. Show me. This is pinnacle of the deceitful nature of the ID and creationist movements. Not only are you claiming that biological evolution is wrong, now you are claiming the work done by scientists themselves was actually done by IDers. What a joke. In academics we call this plagerism. That is exactly what you just did here. And you wonder why scientists get angry at ignorant people like you. I would be hopping mad if I was one of these scientists who conducted this research.
Trader writes: But you can see how their argument was put into a form that brainwashes. It is you and your ilk who are doing the brainwashing of unsuspecting and ignorant people. BTW here is some real scientific articles written by real scientists who have conducted research in this field:
DNA Study Forces Rethink of What It Means to Be a Gene Junk DNA Yields New Kind of Gene (2004) Parasite or partner? Study suggests new role for junk DNA Hints of a language in junk DNA (1994) Thus this bullshit argument creationists are dragging out about junk 'DNA' is actually quite old and has been know in the scientific community for 40 years. This is another case of a thoroughly debunked dog-eared PRATT. Edited by DevilsAdvocate, : No reason given.

Hi again traderdrew, seems there is a lot of recent misinformation posted here: let's see if we can clear it up.
What kind of reply is that? You can't be thinking that I think my thoughts are going to influence the outcomes of experiments like that, which are experiments of natural laws. It is important to be in tune with reality. Exactly, and we know we are in tune with reality when we are not contradicted by the facts. For instance, Behe's "rebuttal" that you have quoted:
Look what Michael Behe wrote: Miller also writes, "the ebg gene is actually only 34% homologous to the gene whose activity it replaces (meaning that about 2/3 of the protein is quite different from the galactosidase gene whose function it replaces)". Yet he knows as well as I do that 34% general sequence homology makes it virtually certain that the three-dimensional structures of the two enzymes are essentially identical. And since the active sites (the business end) of the enzymes are much more similar (they are identical in 13 of 15 residues), the ebg enzyme is pretty much a spare copy of the lac enzyme. Thus it seems to me that the taking over of lac galactosidase function by ebg hardly even rises to the level of microevolution. Once again Miller shows his deceptiveness. Maybe you should be lecturing Miller (not me) on reality. Fascinatingly, the one being deceptive is Behe: it is irrelevant how similar the genes are, similar is not identical. In fact, it is highly likely that a mutation that results in a similar feature would occur on a similar gene. Note that if "(they are identical in 13 of 15 residues)" (= 87% identical) is sufficient similarity for one to be a "spare copy" for the other, then a chimpanzee is a "spare copy" of a human (DNA 95% identical). Curiously, I don't consider 87% identical to be a working spare part - and that would only be the issue if it replaced the original function with a repaired version of the original function. This did not happen. The fact is that this gene alone - without the mutation - is incapable of producing the necessary function. That means that it is not, cannot be, a "spare" copy. To call it such is to intentionally misrepresent reality. Fact: if it was a "spare copy" then there would be no need for the mutation. It did not replace the function without the mutation, and even with the mutation it did not repair the function - it still needed the second part. The other mutation, the second part, involves an even more dissimilar gene:
quote: Now you have two genes that are not the same, both being modified by subsequent mutations, and ending up producing a functional lactose metabolizing system. Fact: these mutation modified genes do not exist in the previous e.coli population, they did not wait to be called upon when the original system blew a flat tire.
Natural selection only replaced one component with a 34% homogenous copy of the original component. Natural selection did not replace anything. Natural selection does not make components nor cause functions to occur: it selects components and functions that exist in the organism by the increase in survival and reproduction the components or functions provide for the organism. Mutations replaced two parts to achieve a functioning system, one with 34% homology and one with 25% homology. Don't creationists like to point out that the DNA of bananas is more similar to human DNA that that? We share 50% of our DNA with bananas
quote: So a little bit of difference in DNA can add up to a lot of difference in the organism.
I don't want to debate or argue about the subject any further. I think we have both stated what we could state. In other words, you don't want to admit that an IC system was actually observed to evolve during the experiment. This is, of course, the #1 ploy of creationism - avoid admitting when you are wrong. However we are also a little off the original assertion you made on the other thread - see Message 229 - which we still need to address:
quote: and your response to my reply Message 240:
quote: This is, after all, what got us here. Interestingly, this thread not only discusses the fact that an IC system has evolved, but that in the process, information must have been added. The reason is simple: after the lactose mechanism was disabled the organisms were unable to process lactose, even though it was readily available, then a couple of mutations occurred that enabled the bacteria to metabolize lactose - by a different mechanism. This is a novel mechanism utilized by the bacteria in the experiment, a mechanism that does not exist in the outside e.coli population, and thus the addition of ability to use lactose means that information was added.
Message 42I disagree with you on two things. I believe it did cease functioning. It has to cease functioning for a least a brief amount of time since those biochemical repairs don't occur at the speed of light. Nor do sequential mutations occur in the same generation. Once again, the system was not repaired, as the original system is still broken\disfunctional\disabled\not working.
1. As I had already stated, when you remove a part of any IC system it has to cease functioning. The questions are, How long did it cease to function? Did Barry Hall have to keep these strains of E. coli alive when the part was removed? It took several generations, hence the substrate designed to allow the bacteria to exist, but not prosper, while also providing the lactose for the opportunity to evolve a system to increase metabolism, survival and reproduction. It did not need to be lactose, nor did the system evolved need to be an IC system.
Could this only be done using IPTG? No. As Miller states:
quote: All that IPTG provides is an environment where the bacteria could survive and where adaptation to metabolize lactose would result in increased survival and reproduction.
2. Was the system of the E. coli not irreducibly complex to begin with? It is relatively unimportant to the end result, however the original system was an IC system. One part of a three part system was removed, and the system stopped working, and the bacteria never again used that system to metabolize lactose. This matches Behe's definition of IC.
Other than that, did the complexity increase? Yes: a new system to metabolize lactose developed by mutation of existing parts, and the new system was selected by the increased survival and reproduction of the bacteria. It's this simple:
From (A) to (B) is a change in information, "X", where X=A-B, and ... from (B) to (C) is a change in information, "Y", where Y=B-C, and ... because (C) = (A) and both ≠ (B), Y = -X ... so either an increase in information occurred, or ... the change in "information" is irrelevant to the evolution of new features and functions. As I said above, this is the other issue that this thread addresses.
If it did increase by a little bit, then it was done with intervention. Are you saying that Barry Hall personally made the mutations on the genes?
If the person who was conducting the experiment didn't intervene, then E. coli would not have been able to hydrolyze lactose. Except that the two independent mutations occurred after the "intervention" where Hall disabled the gene and placed the bacteria on the culturing medium. Barry Hall did not cause the mutations to occur. This, of course brings us back to the issue of being "in tune with reality:"
What kind of reply is that? You can't be thinking that I think my thoughts are going to influence the outcomes of experiments like that, which are experiments of natural laws. It is important to be in tune with reality. Seems you have an issue there to resolve regarding reality. Amazingly, it now seems my comment was predictive, based on experience, and justified.
At least it would have not been done without simultaneous multiple coherent mutations and that would arguably be entering into the realm of metaphysical miracles. Which, incredibly, is not the way it happened, so pretending that it did is just another falsehood\lie\fabrication, that you seem to need to tell yourself to avoid dealing with reality. It's a perfect example of someone thinking their opinion alters the reality to suit their belief.
