SLPx: Please start with:
Evidence that the information for the speciation of the salmon in question was present from the beginning.
I'll give some quotes for my answer:
"Oxford professor Richard Dawkins is generally regarded as one of the most influential neo-Darwinists in the world. During an interview,[31] he was asked a crucial question: Can he point to any example today in which a mutation has actually added new genetic information? (If there is such an example, surely an Oxford zoology professor, promoting neo-Darwinism around the world, would know of it.) Dawkins appeared so perplexed by this question that the Creation organization who produced the video says that Dawkins’ response on screen makes a more powerful point against evolution than volumes written by creationists.[32]
Foolish Faith - Chapter 3: Two Worldviews in Conflict - Mutations: Evolution's Raw Material
quote:
WHAT, exactly, this information is. You must know, for otherwise you would not have claimed that it was already there.
"It is first necessary to briefly define what is meant by the term information in this context. The DNA code has already been defined as a set of instructions, analogous to an English message. The sequence of letters (or bases) in the code is not random or repetitive, but instead, like the letters in a written message. In other words, the code has meaning. For instance, a random sequence of English letters such as NKNTWEIOEIMYTNHATCESGA means nothing, but when the same letters are arranged THE ENEMY IS NOW ATTACKING, it becomes a meaningful message, containing meaningful information. It is the specific arrangement of letters that makes the message meaningful to someone who understands the language, and this meaningful arrangement is, in itself, information. In the same way, it is the specific arrangement of letters (or bases) in the DNA code that makes the code meaningful to the body, which understands the DNA (genetic) language. This meaningful arrangement of letters in the DNA code is what makes up the information that tells the body how to produce a particular physical feature or characteristic, such as an eyeball or hair color.[22]"

quote:
Explain why "no new information" can arise naturalistically.
To answer this, start by providing a biologically relevant definiton of "information."
Support the above responses with verifiable scientific sources.
"Another scientist, Dr. Ian Macreadie, winner of several scientific awards for outstanding contributions to molecular biological research, affirms that all you see in the lab is either gene duplications, reshuffling of existing genes, or defective genes (with a loss of information)But you never see any new information arising in a cellwe just don’t observe it happening. It’s hard to see how any serious scientist could believe that real information can arise just by itself, from nothing.[33]

That is the biggest COPOUT in evolutionism....your whole ToE idea is based on life being in existence, one would think HOW life got there in the first place should also be explained by ToE. Why has the Miller-Urey (failed) experiment been propagated for so many years in biology textbooks under evolution, if it has NOTHING to do with it.
Is it perhaps because it is too embarassing for you guys to talk about?

But, more importantly, are you going to retract the Dawkins "quote" or do you intend to perpetuate that fraud? And answer the specific questions asked of you by SLPx in message #69?
I think you should re-think accusatory remarks. Following is a response to "The Skeptic":
Gillian Brown’s letter to The Skeptic
You have written an article in The Skeptic, which claims to ‘demonstrate the depths to which the creationist movement will stoop in order to try to discredit its critics’, in which you denigrate my character and work, and that without having spoken to me at all.
Your article recounts Prof. Dawkins’ recollection of an interview, which is included in the video From a Frog to a Prince, which I produced, in which Dawkins is seen to pause for 11 seconds, and evade a simple question. As you yourself say: ‘It beggars belief that someone of Richard Dawkins’ stature in the field would have been stumped by such a simple question or would have evaded it.’ So, you conclude that Dawkins was ‘set up’, with ‘malicious intent’, in ‘a piece of crude propaganda’, ‘deliberately manipulated’ with ‘deceitful intent’.
First, if you are going to publish a libellous attack against someone, it is responsible journalism to inquire into both sides of the story. And in this case, before making accusations about the circumstances of an interview, it would have also been wise to have viewed the unedited tape. That way you could have presented a serious investigation of the matter, and avoided making ill-informed and false assertions.
You state: ‘perhaps it could be argued that Prof. Dawkins’ memories of the events might have deteriorated with the passage of time since the interview ’ In fact, whether from memory lapse or for other reasons, the recollection of Dr Dawkins is riddled with inaccuracies and some downright untruths. Following is an accurate account of the interview, which may be confirmed by viewing the unedited video tapes.
Dr Dawkins makes a number of incorrect statements [marked with RD Editor] as cited by Mr Williams to which my replies are interspersed and marked with GB.
RD: ‘On September 16, 1997, Keziah Video Productions, in the persons of Gillian Brown and Geoffrey Smith, came to my house ’
GB: I was accompanied by a former geologist, Philip Hohnen, not Geoffrey Smith.
RD: ‘ I was challenged to produce an example of an evolutionary process which increases the information content of the genome. It is a question that nobody except a creationist would ask ’
GB: That question actually came at the end of the interview. At the beginning, Philip Hohnen asked several general questions on the origin of new information. These questions are recorded on tape and may be viewed, either on tape or transcripted, by anyone interested in the exact nature of the questions. Dawkins objected to the questions and stopped the recording. He claimed that questions on the origin of new information were invalid, and that nobody ever asked him such questions. I responded that the question of information was perfectly valid, and very important to the evolution-creation debate.
RD: ‘The tape having stopped, I explained to them my suspicions, and asked them to leave my house.’
GB: At no time did Dr Dawkins ask us to leave his house. A second camera (newly purchased, which we were testing) was inadvertently not switched off until later, so it recorded most of the ensuing conversation. This remains on record to clarify supposed ‘lapses of memory’.
RD: ‘As it happens, my forthcoming book, Unweaving the Rainbow, has an entire chapter (The Genetic Book of the Dead) devoted to a much more interesting version of the idea that natural selection gathers up information from the environment, and builds it into the genome. At the time of the interview, the book was almost finished (it is to be published in November, 1998). That chapter would have been in the forefront of my mind, and it is therefore especially ludicrous to suggest that I would have evaded the question by talking about fish and amphibians.’
GB: After he asked for the camera to be switched off, Dawkins asked that his answers to the first few questions would not be used (and they have not been used). He then agreed to make a statement, but refused to take more questions from Philip.
We resumed recording, then after he finished his statement I asked for a concrete example in which an evolutionary process can be seen to have increased information on the genome. The long pause seen on the video immediately followed my question, he then asked me to switch off the camera so he could think, which I did.
After some thought he permitted the camera to be switched on again and his final answer was recorded, the answer which appears in the video, which, as can be seen, does not answer the question. Because my question was off-camera and off-mike (though clearly audible on the tape), it could not be used in the finished production. That is why the presenter was recorded later, repeating my question as I had asked it.
Your concern is that the pause was fabricated. No, the pause followed by an irrelevant answer was in response to that exact question, a question which Dr Dawkins could not answer and would have preferred not to even discuss. ‘Ludicrous’ perhaps, but the question was indeed evaded. If you would care to view the unedited tape you will be able to confirm my account.
RD: ‘If I’d wanted to turn the question into more congenial channels, all I had to do was talk about ‘The Genetic Book of the Dead’. It is a chapter I am particularly pleased with. I’d have welcomed the opportunity to expound it. Why on earth, when faced with such an opportunity, would I have kept totally silent? Unless, once again, I was actually thinking about something quite different while struggling to keep my temper?’
GB: Whatever he may have been thinking about I don’t know, but it is clear that he did not answer the question.
[From here, Gillian responds to Barry Williams’ article in The Skeptic<3907.asp> (his comments are marked by BW) Ed.]
BW: ‘If it had been left at that, it might merely have been evidence of professional incompetence on the part of the producer and editor of the tape ’
GB: Before making charges of ‘incompetence’, the original tape should be viewed The question, asked by myself (not Geoffrey Smith) was off camera, and that’s why the question was re-recorded by the narrator, the pause and the answer which follows is exactly the response from Prof. Dawkins.
The actual pause was in fact shortened from 19 seconds to 11 seconds, and Dawkins’ request to switch off the camera so that he could think was also cut out. So, there was no malicious intent whatsoever, what is seen is Dawkins’ exact response, with a shortened pause, and the (merciful not malicious) removal of his request for time to think.
BW: ‘Certainly this is by no means the first occasion on which the creation ‘science’ movement has sought to misrepresent the words of eminent scientists to bolster their own inept grasp of scientific matters, and to mislead their own unfortunate followers.’
GB: This accusation is beneath contempt now that your willingness to make accusations without doing your homework has surfaced. Another skeptic of creation, Glenn Morton, made similar charges on the Internet. He asked Richard Dawkins about it and Dawkins denied recollection of the interview. Finally, after listening to an audio tape of the interview, Dr Morton posted the following apology:
‘ I had originally questioned whether there was some doctoring going on in the tape because of certain technical details that were amiss. The shadows on the narrator were not the shadows from the room in which Dawkins sat. And the room appeared to be different. I wrote Dawkins and asked him about this. He denied having any recollection of this event. I suspected a video hatchet job. After Gillian established contact with me in June, I found that my suspicions were correct that the narrator was not in the same room as Dawkins. Gillian admitted that she had the narrator re-dub the question but contended that she had asked exactly that question and that Dawkins was shown exactly as he performed at the filming [a practice that Williams stated was acceptable Ed.]. Gillian sent a copy of the original audio tape of the interview with Dawkins to a friend of mine. He sent the tape to me.
I will state categorically that the audio tape of the interview 100% supports Gillian Brown’s contention that Dawkins couldn’t answer the question.’

I have found that, by and large, most creationists do not fully understand the very arguments that they confidently make on these fora and in letters to he editor and the like. I have found that by asking them to 'explain' what they mean,rather than just attempting to argue points with them, is very instructive.
If one cannot "explain" what they mean when they write something like "all the information was already present", then there is a good chance that they are just parrotting an argument that they had seen or read about somewhere, it sounded good to them, so they are running with it.
I don't know the stats but I would be quite certain that most people on these types of discussion boards are not experts in some scientific area. What you state above is true to a point, but it doesn't mean that the assertion is necessarily wrong.
If I tried to "explain" my statement, it would be reliant upon research and documentation carried out by experts in the field, and not out of my own mouth, since it is not my area of expertise.
Does that invalidate the point? I should think not.
If you, dr. Page, have a car problem, you take it to the mechanic. When he/she tells you what the problem is, you either get a 2nd opinion (or 3rd or 4th, etc) or you "run with it" because you know that even though this isn't your area (I'm assuming here of course) of expertise, you know that it is the mechanic's.
So, we are faced with two situations, one that says information in the DNA sequence of an organism can easily increase naturally by random mutations, and one that says "‘There is no known natural law through which matter can give rise to information, neither is any physical process or material phenomenon known that can do this.’(Dr Werner Gitt, leading information scientist) His challenge to scientifically falsify this statement has remained unanswered since first published. Even those mutations which give a survival benefit are seen to be losses of information, not creating the sorely needed new material upon which natural selection can then go to work."
Missing Link | Answers in Genesis
When faced with two diametrically opposed answers, what does one do?
A choice must be made based on the information presented. When the observed evidence is that most mutations are either neutral or losses of information, coupled with the documentation from one of the world's leading information scientists stating that new information does not naturally arise, the choice becomes increasingly clear.
Therefore when I say that the information must have been present, it is not based on my expertise (if I have any) but on the assertations of the people whose expertise this area is.

And therein lies the rub. This is an example of arguing via pseudoauthority. Gitt is in fact not a "leading information scientist." He is a creationist information technologist. A glorified computer programmer, basically. Gitt simply ignores/refuses to accept that anything but a "conscious mind" can generate new information. He is mistaken. Motoo Kimura, an actual scientist, demonstrated mathematically in 1961 that, in fact, mutation and natural selection can add new information to the gene pool ("Natural Selection as the process of accumulation of genetic information in adaptive evolution." Genetical Research 2, 127-140. 1961. Kimura, M.)
. Naturally. In addition, many creationists accept that there are natural means by which new information can be added (they just argue that it doesn't happen much..).
I'm short on time (ie. at work) but that was clearly a good demonstration of a smokescreen ad hominem.

That is, for example, how is it that a lawyer can know that what he and his pals claim regarding evolutionary biology is correct when this lawyer admits that he has litle knowledge of the topic?
The answer is, of course, he cannot.
The claims might be correct, but he has no way of knowing, but insists that they ARE correct nonetheless.
Here is a nice axample of a non-sequitur. Of course a brilliant lawyer can know whether what he is saying is correct, he just has to do some research (which I am sure Dr. Johnson does lots of...you were talking about him right?)

SLPx, you are avoiding the issue by focusing on the man, ergo ad hominem.
The problem is not that Dr. Gitt is not a world leading information scientist, but rather that the scientific community (pro-evo) does not like what he has to say.
Lets look at this another way.
Perhaps you will answer these questions:
1. how often do mutations occur?
2. what is the most common result due to mutations?
3. how many beneficial mutations can you describe?
Thanks,
S.

So if mutations are rare and have no effect, what is the legitimate reasoning behind using them as the backbone for creating new raw material for species advancement?
Also, most diseases, are they not caused by mutations?
Finally, why do you (along w/ everybody else) throw the "beneficial mutation" question back at me?

This is why those "impossibility of abiogenesis" claims are irrelevant - they are (at least ALL of the ones I have seen) based on 1-trial events. They neglect the fact that there would likely have been millions of such 'trials' every second.
Look at a lottery - buy one ticket, you have a pretty slim chance of winning. Buy 100 million and you will most likely possess a winning ticket.
Same idea with abiogenesis.
Evidently (at least so I've been told many times) abiogenesis has nothing to do with evolution.
quote:
Of couse, it is relatively easy to find a genetic cause for a disease. But do diseases take away limbs? That is, anti-evolution?
Since the claimed 'requirement' for evolution, as described by creationists, is 'beneficial mutations' that do things like produce 'new body parts', why then do not detrimental mutations - genetic diseases - cause a substraction of body parts?
Take away the ability to appreciate music, etc.?
How about loss of hearing, sight, loss of limbs due to deadly viruses. Would that count?
quote:
So, please define for us YOUR use of "beneficial mutation.
Something that isnt neutral, doesn't cause genetic disease or other harm, something that would add an entirely new function superior to any other equivalent function.
I suppose that is what the creators of Spiderman, The Hulk, etc envisioned. And in comic book land, it works beautifully, but unfortunately not in this world.
Does that suffice?

quote:
Mutation has the ability to add new information. Some common mutational mechanisms that produce new information are base substitutions, gene duplication, gene insertion, transposons, chromosome duplication, and a host of other copying errors. Even mutations that simply replace one nucleotide with another are examples of new information, because the new nucleotide sequence represents a new allele not previously present in the population (an allele is a type of a specific gene, such as the gene for eye color, one allele for blue, another for brown, etc)
Here's a simple example of the process of creating new information by substituting a single nucleotide. Let's consider a single gene, call it the X gene, in a population. This gene has only two alleles, call them A and B, and let's say these are the nucleotide sequences for the two alleles:
A: AAGCTTGTAACAA
B: CCGTCATTCGATC
During reproduction let's say a mutation occurs in one nucleotide of allele B, thereby producing new allele C, so now the population's gene pool has increased in size by one allele (note that C differs from B in only a single nucleotide):
A: AAGCTTGTAACAA
B: CCGTCATTCGATC
C: CCGTCACTCGATC
Does the new allele produce a difference in the organism's phenotype (phenotype means all characteristics of an organism, including morphological, chemical, psychological, etc)? Perhaps. And if it does, will it increase or decrease the organisms likelihood to survive to reproduce? That's what natural selection will decide.
Mutation is the source of new information, and natural selection is the pruning mechanism that decides which mutations pass on to the next generation.

I want to back up to this point again. I believe it was SLPx who asked me to define "information", and I think it is appropriate to do so now. A simple illustration will do:
Suppose I write a one page letter, I then ask the secretary to type the letter for me. She does (except she makes a few typographical errors). Now we have my original letter, and a near perfect copy of my letter. The copy is not new information, it is merely a duplicate of an original (and a worse one at that).
Now, suppose I write a one page letter and ask a friend to write a one page letter (on any topic). We would then have two entirely different letters, representing new information.
In the first scenario we ended up with two letters of the same information (except lets say one point in my letter was to "purchase 10 litres of milk" and the secretary typed "purchase 1000 litres of milk"...that would have serious consequences if I only had money for 10).
In the second scenario I write a letter about dogs, and my friend writes about the space shuttle. Two entirely different unrelated things.
Percy, your example would be more accurate to say that you now had three alleles, A, B, and B(2) ie. a less than perfect copy of the original B. So it's NOT new information, but rather a copy of the pre-existing information.
Just as there are over 300 alleles of the hemoglobin gene, but all those alleles only produce hemoglobin.
Mutations produce only alleles, which means that they can only produce variation within pre-existing created kinds, and not change from one kind to another.
SLPx, what if one of your students handed in a 26 page paper, but upon reading it you discovered that each page was exactly the same. The student merely copied the first page 25 times (probably made some typo's if he/she re-typed each page).
Would you call that NEW information?
Regards,
S

The first thing I do is explain it using the 'language analogy' - letters, words, sentences...
Then I explain that this analogy breaks down and is useless above this very simplistic level..
Unfortunately, gene action is in fact not at all like typos in a letter.
Nor is gene duplication just like typing a sentence twice.
Would you mind explaining the what's and how's of gene action/duplication?
Thanks

Sure. Keep in mind that this will be brief and will not be a universal explanation. That is, there are lots of exceptions, etc.
Would you mind elaborating on these "exceptions"?
There are several ways that organisms control the amount of each gene product being expressed. For instance, we do not need or want huge amounts of growth hormone being produced all the time. There are feedback mechanisms, where, for example, the gene product itself or some metabolic byproduct either enhances or slows down further production.
There are ways to turn genes off permanently, such as those used during embryonic development. There are ways to turn genes off temporarily, and so on.
How does evolutionary thinking explain such control mechanisms?, ie. how they evolved.
Increasing the amount of gene product is not just like reading a sentence twice, at least not in most cases. There are interactions between proteins and other molecules, many of which are concentration dependant. Small amounts of protein X are fine, but double it and all sorts of new interactions occur.
In what cases is it like reading a sentence twice?
Can you post a link again to this mice experiment. In a search I found that the limbs got shorter but not longer.
Thanks,
S

Typical...
Did you understand what I did write?
Or were you just looking for 'questions that the evo can't answer' to hang your hat on?
I'm not looking to hang my hat on anything. Your answer brought up some interesting new questions, and I simply was looking for answers, to try to understand the whole scheme. Curiosity begets information and knowledge.
Are you telling me that no one has the answers to my questions?
If you know the answers, I would still like to know them.
Thanks,
S
