In eithre event Spontaneous generation has been disproven for a long long time.
How did Pasteur's experiments disprove abiogenesis? Did Pasteur even look for simple RNA replicators?

I agree that this is a layman's interpretation of a lot of technical terms, but I certainly never hid that Koch proposed a mechanism how to explain it.
If you are going to quote Koch posing a problem you could at least quote Koch's answer to the problem. It is the honest thing to do.
The argument is proposing an accepted mechanism for IC systems: intelligent design. We have observed designers and engineers make IC systems fro mas long as we can remember, we know that intelligence can produce IC systems.
However, the only intelligence we know of that produces IC systems was not around when these biological IC systems came about. Therefore, ID fails as an explanation.
And all the naturalistic propositions to explain it all come down to the same thing: making multiple steps at a time. It is my contention that this could be deduced logically.
Then go for it.
What characteristics makes an intelligent capable of producing an IC systems ? It is, as I said earlier, it's capacity to plan ahead, foresight. It can plan ahead that if you put all these pieces together in a specific way, you will get a useful outcome.
You have not shown that IC systems require foresight.
So if each step towards any system is detrimental (as is the case with a IC system), . . .
There is no reason that an IC system must require detrimental mutations in an evolutionary pathway.

However, the case seems to be different with DNA. The information in DNA does not come from any interaction it has, but from an established code which we have all seen:
This is false. It is the chemical and physical interactions between DNA and it's environment that produces the effects we see. It is the physical interactions between RNA polymerase and DNA that produces messenger RNA. It is the physical interaction between gene regulators and the DNA that results in gene regulation. The interaction between proteins is EXACTLY THE SAME REACTION that occurs between DNA and proteins.
Now, how this code was established is the crux of the matter. There seems to be no physical, chemical reason that this code should be what it is. It just is, and it is the sole thing that gives DNa any information value.
Are you serious? It is the PHYSICAL INTERACTION between the anticodon on tRNA's and the codon on the mRNA that results in a specific amino acid being added to the elongating peptide. This interaction is due to the available hydrogen bonds of the nucleotides themselves with G's and C's having three available bonds and T's and A's having two. G's interact with C's, C's to G's, A's to T's, and T's to A's, and it has EVERYTHING to do with the chemistry and physical nature of the nucleotide bases themselves.

What characteristics of humans make them able to construct IC systems ? Is it the fact that they are a biped mammal ? Or is it their intelligence ? Or is it something else ?
This still does not refute the inductive argument that all IC systems were produced by humans. Until you offer a counter-example the argument stands, by your own rules.
It is that intelligent beings foresight makes them able to construct IC systems.
Which is irrelevant to the origin of IC systems. It takes foresight to make a freezer that can freeze water. This doesn't mean that every piece of frozen water requires an intelligence.
It requires individually detrimental mutations, but collectively beneficial mutations. So these mutations must come about all at once, or at least appear to NS all at once. This is the basis of what Koch is talking about.
In every case? The irreducibly complex mammalian middle ear did not require two reptillian lower jaw bones to stop functioning until those bones evolved into middle ear bones. Both the middle ear and the lower jaw stayed function through the entire evolution of the system.

You're missing the point. The code isn't descriptive of the interactions; GAA isn't any more physically attracted to Glutamic acid then CAC.
GAA is more physically attracted to the CTT on the tRNA for glutamic acid. That is why a glutamic acid is added to the peptide. It is the physical interaction between the anti-codon on the tRNA's and the codon on the mRNA that results in the amino acid sequence.
ABE: That should be CUU. I always forget to replace uracils for thymines.

Re: John Woodmorappe
But I didn't quote Woodmorappe, I just used the same Koch quote he used.
That's a bit of a faux pas. When you quote someone you should try to pull it from the primary source, not from a secondary source, or even worse from a known liar like Woodmorappe. Given the track record of creationist quote mines I would strongly suggest that you check the context of the quotes before posting them.

So why is that particular amino acid charged onto that particular tRNA? I think that's what he's getting at. And that IS arbitrary, at least to some degree.
While it may be arbitrary it is still tied to physical interactions which contradicts slevesque's claims. It is the physical interaction between the tRNA's and mRNA that results in the amino acid sequence. The very shape of the tRNA's is dependent on the physical interactions and sequence of the nucleotides in the tRNA.

No. If you read the last post you responded to he's saying that the codon-amino acid link is arbitrary. Which is it. The process is physical, yes, but you can't explain the coding itself in such simple terms.
It may be a case of talking past each other and differences in how one views these genetic systems. We can explain the coding in terms of physical interactions. The enzymes involved in attaching the amino acid to the tRNA phsyically interact with the tRNA's just like any ligand-receptor interaction which slevesque described as being different from genetic coding. The interaction between the tRNA, ribosome, and mRNA are all physical interactions that are dependent on the physical characteristics of the nucleotides themselves. Even the multiple hairpin shape of the tRNA's is an intrinsic property of the physical interactions between the nucleotides within the tRNA. That physical shape is necessary for the specific recognition of each tRNA in the whole process.
When I view the whole process I see all of the physical interactions and how they relate to one another. I don't see strings of letters on a screen. Perhaps this is why I am having difficulty in understanding how it is anything but the physical interactions that drive the genetic systems of a cell.

But the actual amino acid codings? They're arbitrary.
That could be said about every protein-protein interaction. The relationship between ligand and receptor is always arbitrary, but it is intimately tied to physical interactions. What goes into a series of enzyme reactions and what comes out the other end is arbitrary, and this is true through the entire cell from metabolism to cell-to-cell communication to genetic systems. There is no physical relationship between ADP and ATP, and yet there is a physical system in mitochondria that transfers a phosphate to ADP to produce ATP. This process is no different, from a fundamental physical view, than the process that guides the extension of peptides.
So the coding itself is not a physical certainty; it's a convention.
Yes and no. Given the physical characteristics of the ribosomes, tRNA's, mRNA's, etc. it is a physical certainty that the specific codon will result in a specific amino acid. Could it have been different? Yes. If you changed the physical characteristics of the macromolecules involved then it will change the physical interactions and a different outcome will occur.
Many people use computer language to describe how DNA works. I think this is a mistake. A better, yet still lacking, analogy is the gears of a clock. It is the physical interactions of the parts themselves that produce the outcome. While our units of time may be arbitrary and could be different this doesn't mean that the output of a mechanical clock is not tied to physical interactions.
I am trying to keep this in context with slevesque's comment from message 269 which stated:
quote:
The difference I see is that the information you are talking about is directly related to how it physically interacts with something else. For example, a protein's interaction with a receptor, or any other molecule, is what gives it any information.
However, the case seems to be different with DNA. The information in DNA does not come from any interaction it has, but from an established code which we have all seen
I took exception to this argument. The information in DNA is a result of it's physical interactions with proteins and other biomolecules. The genetic code is a result of physical interactions just like those seen between receptor and ligand. I don't see how you can claim that receptor-ligand interactions are fundamentally different than DNA-protein interactions.

Once again IC has a specific definition, and the IDers use it as evidence for design because it happens to be that the only currently known way to produce such a system is through design.
The problem is that you don't have a designer for the IC systems seen in biological organisms. Given the finite history of our universe there has to be a First Designer somewhere along the way, and there is every reason to believe that in the case of Earth that humans are the First Designers.
Also, the actual concept of IC is rather lame. It boils down to, "if you break something it stops working". You can put lipstick on it all you want, but that is pretty much it.

Re: Many ways to create an IC system.
In biological systems, 'steps' are simply mutations. To evolve IC systems, you need to have multiple simultaneous mutations.
Nowhere have you shown that this is true. You have simply asserted it. We need evidence before we can proceed.
If you doubt this, consider that all researches that try to find a mechanism to evolve such systems approach it by trying to find a mechanism in which multiple simultaneous mutations will become visible to selection.
Now would be that time. If you have the research to back it up then present it.

It is not a necessity that I identify a specific designer, it would be better I guess, but in no way does it negate the argument.
No designer = no design.
Well, ''the argument is lame'' isn't an argument. First because it is subjective (someone might find it astonishing) and second because you phrased your boiled down version of it to fit your need to see it as 'lame' ...
If you break something it doesn't work, therefore design.
It certainly isn't compelling evidence.
