Etheired,

The solution you seem to have for every mystery is “evolution did it”.
I asked for a step by step explanation for the supposed evolution of the code. Your answer is essentially “evolution did it”.
I will show you what I mean by the irrelevance of your post and your unnatural faith in evolution to be trusted to work miracles without the need of explanation.
First I will answer your questions again:
1. The proof is (as I explained earlier) in several thousand years of common experience just like gravity was a known reality before any proof was offered except that apples fell to the ground and people didn’t fly off of the planet etc.
There is a long unbroken chain of history of codes that have always originated from a mental process.
This is a premise that isn't justifiable.
There is no exception.
If you say that evolution can do it then you are expressing blind faith unless you can actually show HOW evolution did it by actually answering the question,i.e., How did the CODE and the LOGICAL ORDER OF INFORMATION within it arise?
We don't know how the electrical circuit experiments worked either. You are ignoring this reality of course. Evolution worked there and there is no reason at all to think it could not refine whatever the precursor to the present code was.
2. Read some history of codes. I am not going to do your homework for you.
If you are claiming that your argument is valid because you are ignorant of the facts then I guess you win the debate
It was obvious from the start that you intended to use flawed logic based on arguement from definition.
The basic flaw is this:
All codes we you know of are created by inteligences therefor DNA was created by an inteligence.
That is false.
The true statement would be:
MOST codes are created by humans therefor an inteligence was involved. DNA was not created by humans therefor the source of it is open to question.
– Yes, you are ignorant of the source of all codes in existence
I justify my premise on the present reality of the origin of all codes via a mental process and a justify it on the basis that there is not one exception to the rule.
Anyway here is some of the homework that I have done for you so you have a place to start:
Here learn something about evolution. You appear to know little about it that you didn't learn right here.
3. A sender is required besides the environment because there must be a convention with the receiver (see first page).
There was not convention in the original molecules just something that can be copied. It would have originally been a one unit to one correspondence. There is nothing stopping this from changing after there is a seperation of jobs. The 'convention' would have started as a one to one molecule to molecule thing.
The key concept in the evolution of DNA is that sectiong are often copied twice. This allows one copy to do the original job and the second copy to evolve to do a different one.
The earliest DNA would have had a one to one correspondence with the RNA that it replaced. I am assuming here that the code arose after the development of DNA but it need not be that way it just seems a bit more likely to me. I am assuming as well that originally the ribosome was primarily if not completely RNA with little or no protein involved.
What this allows for is the DNA to code for the ribosome in a one to one corespondence and the extra duplications to begin to cause the ribosome to produce proteins mostly by accident at the start. Since there is no inherent one to one corresopondence between tRNA and amino acids some segments of tRNA would have an affinity for one amino acid over another.
The DNA is not evolving a code. The ribosome is. As the ribosome evolves over time it can develop a system. There is not actual communication between the ribosome and the DNA nor need there be any such communication. As long as the DNA continues to produce a functioning ribosome that is now mostly relegated to protein production the ribosome can evolve a better way to convert the data it recieves via tRNA to protein. There is no reason to say it could not change to have the minimum code that we see today. Its likely that in the beginning fairly long stretches of tRNA would be needed to cause an amino-acid to join to another. With modifiction by evolution these could gradually become more efficient by reducing the length of the tRNA need for any corresponding amino-acid and for a greater precision of what amino-acid would actually correspond the section.
What comunication there is is all one way. The ribosome does not tell the DNA anything. It simply translates it into amino-acid strings. Because of this there is no need for a convention between the two. Its the ribosome that is what decides what will be produced for any stretch of DNA not the DNA. The DNA has no say in the matter of the tranlation.
For instance. There never was a convention between the Japanese and the American Black Chamber. Hebert O. Yardly didn't even know Japanese when he cracked the Japanese dipolomatic code. Now that isn't an exact analogy of course. Its simply an example of one way communication without a convention.
The environment cannot decide or make value judgments in order to assign meaning to the symbols of the code.
The triplets or codons in DNA do not have a one to one relationship with amino acids. You cannot take the codon made up of Uracil, Guanine, and Cytosine and make cysteine.
UGC only MEANS cysteine.
The codons must be translated into another code which is not 4 letters of 64 triplets but 20 amino acids and 64 triplets. Without assigning meaning there is no way to go from UGC to cysteine.
That is why it is called a “genetic code”. It is an actual code that has meaning assigned to the particular chemicals.
The chemicals on their own cannot send the meaning and they on their own mean something chemically irrelevant to the finished product. They only react according to the laws of thermodynamics.
A mental source is necessary to assign meaning to the representative chemicals.
The environment cannot think like that and see the necessary goal of translation.
Now, please don’t parse this paragraph.
4. Chemicals cannot know something of the future except they will always react according to the laws of thermodynamics. That is all they ‘know’.
The knowledge of a code and its translation and the meaning of its symbols (in this case chemical symbols) comes from a mental process.
In order to propose a purely materialistic process for a code then the chemicals must be ascribed mental powers that they obviously do not have. I am proposing that the code arose through a mental process like all other codes. He who would propose that chemicals can do it on their own are suggesting that they have knowledge of the future translation.
Yes we are trying to solve an actual problem. We are not building a strawman.

There is not one word in all of the above that leads from a non-code environment to the coded one that actually exists in a cell. Only the statement of faith; “The code can evolve in steps...” or what I call the “evolution did it” argument. Now after the cell is functioning somehow without a code which is required in all cells in existence on earth, we procede:

Once a code arose those cells with a code would soon be the only survivors. There is no reason to expect to see a codeless cell today. Again you are mistaking life today with life in the far past.

Okay, we are finally getting to the relevant portion, i.e.
So a cell exists without codons at this point? How does the ribosome produce a string of amino acids without knowing the correct order?

Eventually a marginly useful string would be produced.
How does more random proteins help in the formation of the code? Where is the translation process now?
What has evolved to make translation now inevitable?
How do proteins “modified through evolution” help to assign meaning to the particular codons?
How did tRNA form itself to match both the codons in DNA and the ‘proto’-ribosmes? If there are no codons at this point what are they doing?
Which gives me an idea about modern DNA. There are large sections that don't code for proteins. 95% in human DNA. Some of these might not be coding as much as it is a simple one to one corespodence for the RNA in the cell. The RNA in the ribosome has to come from somewhere and in this model of mine the DNA started as RNA which started as a self-reprocing molecule that later became the ribosome. Looks good to me anyway. Maybe I should try to publish this muddling.
How are proteins produced that help to translate the code? The data being stored is or is not in triplet form now? How are the triplets discerned from the string of DNA? How is ‘evolution’ producing a code here?
However I think that transcriptase, even today, has no understanding of most codons. Just the start, stop and skip type things. There is no need for anything but the ribosome to deal with any other codon.
So your step by process is summed in the words; “That is where the code comes in”.
In other words your entire scenario though interesting is irrelevant to the question and to use a word you like to toss around – obfuscation.
Clouding the issue with endless words and parsing of other people’s comments really does not prove anything except that you cannot answer the question other than to say, “evolution did it”.
As for my breaking things up. Thats the way I do it and the irritation it causes those that can't stand the detailed analysis of their statements is gratifying. Perhaps it would be best not to let the irritation show.
Think of this as the linear equivalent of marginal glossing. If I could put the comments on the side of the original I would.
The rest of your post is more of the same "survival" and "evolution did it" routine with no answer to the actual question of code evolution.
Yes I know that evolution is based on survival of the fittest but your endless explanations of that principle is really just an evasion of the actual question. How did the code evolve?
