You are implying that no information is added and that everything comes about by altering already existing information. That is like saying there is no difference when it comes to the amount of information in something as simple as a bug compared to a human.
Lets pretend the sentence I am about to type is information:
Every Bird Has Wings- if the information is altered then it might come out like this: Evrey Dirb Ahs Ignws. Although there was some change nothing was added because it is still micro-evolution. If somehow a new word was added to the sentence then it would show macro-evolution.

If it's not the same as it was before then indeed, it is different. What else would "different" mean?
Do you want me to say new? then yes its new. As new as someone buying a car that had most of its parts replaced with old parts. The car will be new to you because it is not the same as before.....but it hasn't really given you anything different then what you already had. That is accept your probobly going to get a loss of quality when compared to a new, new car or some other wierd problems.

What do you think fish would need to use legs that they don'thave, besides legs?
It's not that they don't have muscles, bones, a nervous system to control them. Its that there are no genes to specify how the limb is to be attached to the nervous system, what muscles need to go where, what type of bones need to be present, and where they need to be placed in order for the limb to work properly are present. You are only left with a fin and the information to set it up. You could alter that fin all you want but your not going to get the new information needed for the leg. You might get a different variety of fins, but they will always be fins because thats what its information is the blueprint for.
"Postdoctoral fellow Malcolm Logan and Clifford Tabin, professor of genetics at Harvard Medical School, took a gene that is normally only active in legs and transferred it to the forming wings of chick embryos. The resulting structures lost many of their wing characteristics and gained those of a leg: feathers were gone, claws appeared at the end on the digits, and leg-specific muscles were clearly identifiable."(http://www.hms.harvard.edu/news/releases/399limbgene.html)

Um, no, I'm not. I'm merely making the rather obvious observation that when you alter existing information, you're adding new information.
That is like saying there is no difference when it comes to the amount of information in something as simple as a bug compared to a human.
In many species, there isn't. Humans have only 46 chromosomes, you know. Somewhere around 14,000 different genes. Do you think that's a record, of some kind? That there aren't other species with more genes, more chromosomes?
The car will be new to you because it is not the same as before.....but it hasn't really given you anything different then what you already had.
Except, obviously, a car.

Those genes are indeed present. They're present as the genes that connect fins to the nervous system, etc.
Brilliant quote, by the way. It pretty much proves my case - it takes very, very little information - possibly even one single gene - to give rise to drastic phenotypical change.
I mean, what did you think it said? Did you really think that one single gene could have encapsulated all the information to grow a leg?

Is all the information encapsulated in the single gene? No not all of it but the loss of feathers, the claws, and the muscle placement was. Without that gene the muscles would not appear in the correct places and the leg could not function. Mutations have never been know to add information that I know of. So how is it that new muscles would appear in a fin, that were positioned in new places which allowed them and the bones to change? without genes that alow the bones to grow differently and the nervous system to attach in a different order, that fin is not going to change. You can alter the fin genes all you want, its not going to make the fin as complex as a leg because it will only alter the atributes of the fin.
The quote that I posted shows that a gene for a leg is not like a gene for a fin. It shows how important it is that a gene is added with more information rather then altered information.

Who said anything about it being a record? I didn't, so why did you say that? I was simply saying that if you believe in evolution you must believe in macro-evolution because there are differences in information amounts. I gave an example of how information is different so you would see that information needed to be added at some point. I wasn't having an information race or anything.

Mutations have never been know to add information that I know of.
But you know this can't be true, right? We know that mutations change genetic information, right? Change what's already there?
And we've alrready agreed that when you change what's there you've added something new. So we know mutations are adding new information.
without genes that alow the bones to grow differently and the nervous system to attach in a different order, that fin is not going to change.
But it is. Your quote shows that a single gene can cause these kinds of changes.
There's only 14,000 genes in the human genome, remember when I told you that? Since that's true, the way that you understand the genetic basis for phenotype must obviously be wrong. There's simply not enough genes for there to be one gene for the bones for a finger, one gene for the muscles in a finger, one gene for the skin on a finger, one gene for the nerve connection, one gene for the part of the brain to move the finger, one gene for the part of the brain to percieve the finger - you get the idea. There's no way there's enough genes for all that genetic detail, if all those things have to be their own genes.
Genes don't work the way you think they work. A single gene can "turn on" a leg or turn a fin into something else, even if it doesn't contain the information to do so. It simply tells other genes to use the information they contain in a different way.
The quote that I posted shows that a gene for a leg is not like a gene for a fin.
The quote you posted doesn't say anything about fins.

The Mutations are not adding new information. It is altering already existent information. You are not adding anything new, you are only altering the information that is already present. I didn't say that when you change what is there you add something new. I said that if you change what is there it is different then it was before. Because it is different it SEEMS new, but nothing new was actually added to the information therefore it is not new.

If you would go back up to where I was talking about the gene and the chicken. You will see that I understand that a gene does more then one thing.
Genes don't talk to each other. When the embryo is in the womb the genes don't have detailed conversations about how they want to build the thing in the embryo. All the gene's for muscles don't get together and say "we should puts some of us over here that way the bone will move better.....wait bro we should tell the bone about our plan...I don't think he would like us pulling on him for no reason." It just doesn't happen. The information doesn't change unless a mutation accures that alters the way the current setup is. It will do things like make the fin longer, have a muscle growth, have a smaller fin, and so on. Unless a new gene with the information shows up for a new organ, system, muscle placement, bone placement, and so on; the mutations are going to be pointless. Without added information, NOT altering the already existing information. It is IMPOSSIBLE to get new working appendages. You can argue that all you want but many evolutionist already understand it. Why else would they be trying to make a theory to explain how Macro-evolution is possible? If Micro-evolution was able to explain Macro-evolution then they would not need a theory. But it doesn't. Earlier, I think in my first post I put to words in (). Google those words seperately. They are theories that are in progress and will make it easier for you to accept the nessesity of Macro-evolution in the evolution of new organs, genes, information, and so on.
In our 14,000 gene's we do not have any, fin, or gill gene's in my opinion. When we are in the womb at each stage we are human, there are no gills and embryologists will tell you that. Haekels chart is really decieving. It annoys me that they teach such false proofs even today in school.

Perhaps you could tell us what you think would constitute new information?
What about gene duplication? Would you have new information if your sentence became 'Every Bird Has Wings Wings-', what about 'Every Bird Has Wings Wongs-', do any of these contain 'new' information?

In our 14,000 gene's we do not have any, fin, or gill gene's in my opinion.
How much weight should we give to your opinion? There are any number of genes which are expressed in the fin which are also expressed in the limbs of animals without fins. The very genes in the research you yourself referenced determining hind limb speciificty, Tbx4 and Pitx1, are also found in the pelvic fins of fish. Similarly Tbx5, which is thought to specify forelimb identity, is expressed in the pectoral fins (Ahn, et al., 2002).
In one of the many other Haeckel based threads there was a discussion of some recent work on the expression of genes whcih are expressed in gills which are also expressed in organs involved in osmoregulation in vertebrates without gills (Okabe and Graham, 2002).
So do you have any evidence to back up your opinion?
TTFN,
WK

I read an article once where the author explained that "cookbook" is a better analogy for DNA than the often used "blueprint". I guess that is applicable here?

The Mutations are not adding new information. It is altering already existent information.
But you already agreed that changing what is there is new information.
I'm sorry but I don't understand the problem. Do you believe that you can agree that changing is adding, but continue to act like you did not agree?
I said that if you change what is there it is different then it was before.
And you agreed that "different" was "new." I'm sorry but I don't understand the problem here.
Genes don't talk to each other.
Yes, they do. Genes are controlled by signals from other genes. Many genes exist whose sole function is to control the expression of other genes.
Unless a new gene with the information shows up for a new organ, system, muscle placement, bone placement, and so on; the mutations are going to be pointless.
But I've just proved to you that that's not the way genes control phenotype. There's simply not enough genes for that kind of genetic information to be encoded in the genome. Your genome is not a "blueprint", there's not a little map of your body encoded into your cells somehow.
Why else would they be trying to make a theory to explain how Macro-evolution is possible?
I'm sorry? What theory is that, exactly? Who do you believe is working on it?
In our 14,000 gene's we do not have any, fin, or gill gene's in my opinion.
No. Neither do we have bone placement genes, nervous system layout genes, or any of the other fake genes you've been making up in your posts.
It's going to be very difficult for you to understand the genetic basis for evolution if you don't know anything about genetics, and aren't willing to learn.
Haekels chart is really decieving.
No, it's really not. Haekels' chart doesn't show gills, it shows that human embryos share structures called "pharyngeal arches" with fish and bird embryos that, in fish, develop into gills; in birds they develop into parts of the ear, and in humans they become parts of the jaw as well as the ear.
It's a brilliant proof of the fundamental principle of evolution - evolution proceeds via modifications to what is already there (gill structures in fish embryos), not by inventing brand new structures from whole cloth.

Im not familiar with gene duplication, but it seems almost like adding new information. Only thing about it is that it doesn't seem to bring anything new to the table. Like I said im not expert at gene duplication. So all I can do is quote what others have to say on the subject.
" If this process had been an important factor in the ‘evolution’ of life, then we should find that the number of chromosomes and/or the mass of DNA per cell would increase as you move up the Tree of Life. The organisms with the most DNA should have had the greatest exposure to mutation and thus the greatest opportunity for evolutionary advancement. Bacteria and other single-celled organisms should have the least amount of DNA, and complex organisms like man should have the most.
Is that what we find? Not at all. Some microbes have more chromosomes and more DNA than man. Man has only a modest 46 chromosomes, falling somewhere in the middle of the range that goes from 1 chromosome in an ant (quite an advanced organism compared to a microbe) to over six hundred in some plants. "
An example of information: A one-celled organism does not have the instructions for how to manufacture eyes, ears, blood, skin, hooves, brains, etc. which ponies need. So for protozoa to have given rise to ponies, there would have to be some mechanism that gives rise to new information.
Without some way for the information to be added then Macro-evolution can't happen. I am not dismissing the whole theory of Macro-evolution, although I don't believe it, I am only pointing out that without a logical way to gain massive amount of information it won't happen. the problem is that if mutations were capable of adding the information required, we should see hundreds of examples all around us, considering that there are many thousands of mutations happening continually. But whenever we study mutations, they invariably turn out to have lost or degraded the information.

Im not going to say the mutation added something that wasn't already there. It just altered it....I mean you can say it is new because it is not the same as before....but its not really different.
crash, please stop pretending that I gave altered information the merit for being brand new. I gave you an example of a car that had its parts altered. It was the same car but could be classified as new because it was not the same as before. Because it is different does not mean that it has added anything new to it like a body kit, or a leg.
In simpler terms New can mean- different or new can mean brand new. If you kept altering something with very little complexity, without giving it a wider canvas to work on, you are not going to get something complex. You need to first find a way for the canvas to be extended. Or add information.
Another example of Macro-evolution:Remember, evolutionary belief teaches that once upon a time, there were living things, but no lungslungs had not evolved yet, so there was no DNA information coding for lung manufacture. Somehow this program had to be written. New information had to arise that did not previously exist, anywhere.
