[B][QUOTE]I found the above, which, even discounting the organic carbon impurities, suggests that UV-B (at least) is rapidly disapated in water. So if the amino-acids were at deep-sea location, that wouldnot be such a bar to production I guess.

[QUOTE]Originally posted by Peter:
[B]A dust cloud resulting from a large enough asteroid collision could produce particles in the atmosphere which would dissipate UV radiation It is considered that in the early life of the solar system such impacts were not that rare.[/quote] [/b] I'm thinking that most of the high frequency impact period would be over by the time we could start to think about abiogenesis. So as an energy source and UV shield, I'm not betting on asteroids. As suppliers of organic molecules though, they seem likely candidates.
quote: I suspect mantle heat release to have been very important, but not as a result of impacts. Hydrogen sulfide spews out of hydrothermal vents to this day. Last I heard, hydrogen sulfide eaters are considered to be the first complex organism. Still, that doesn't mean they were the first. In fact, they are pretty far down the chain it seems to me. ------------------http://www.hells-handmaiden.com

quote: Sure. I don't see why not, but whether it happened that way or not I do not know; and don't have time to try to look it up right now.
quote: That's how I understand it as well. The first billion years or so would have been hellish for that reason. The next billion, when life got its slow start, I don't know about. I need to check. ------------------http://www.hells-handmaiden.com

quote: Lol... that would be interesting.
quote: God encoded in ASCII and UNICODE, eh? I don't think so. We made that stuff up. The only rational search would be for numbers, and then convert them to letters based on the ancient hebrew use of letters to represent numbers. God, obviously, spoke Hebrew.
quote: Knock yourself out. Remember, you are going to have to get significantly long, exact quotes without resorting to statistical scrambling of the sequences-- as per, Bible Code investigations-- or the results will be invalid.

quote: That isn't DNA's goal. DNA doesn't have a goal. DNA doesn't care if the species comes or goes, lives or dies, anymore than oxygen cares that metal oxydizes in its presence. DNA is just a molecule. It reacts with other molecules. That's it. We see the results and put a label on them-- life. But you can't argue backward from results to goals. We see the results of the combination of oxygen and hydrogen atoms. Do you really think it valid to claim that the result-- water-- is the goal of oxygen and hydrogen. We see a result of the molecular structure of water-- ice. Is that the goal of water?
quote: No it isn't. There is no goal. You can just as easily argue the reverse. More species have gone extinct than survive, thus the ultimate goal of life is extinction.
quote: What equation is DNA targetted to solve? Survival? A lot of molecules survive. Replication? Every replication is altered. It doesn't solve that equation very well. Survival of the species? Species are always changing and more lines go extinct than survive. It doesn't solve that equation very well either.
quote: hmmm.... I thought we had a program. Now we have the whole box.
quote: Agreed. We might be able to tell what it does, but not what it was designed to do.
quote: There is no intent. It is a consequence of the mechanical workings of the parts. The intent was on the part of the designers. The machine doesn't embody intent or purpose. You want to argue backwards from what you see it doing to what it was designed to do and even to the conclusion that it was designed. Here is the problem. We don't infer that machines had designers because we see them doing something. Everything does something. We infer design primarily because we recognize human technology. We know what we build, we know the materials we use, and we know what our constructions look like. It is pattern recognition. None of these considerations apply in the case of DNA.
quote: There is no goal.
quote: Wrong. We have chemical processes. DNA is just chemistry.
quote: An inference is not the same as absolute knowledge. The last phrase in the sentence underlines your whole argument. We know what the thing does right now, but not what it used to do or was designed to do. This means it may once have done something very different or nothing in particular. If either is the case, you can't infer that it was designed to do what it does.
quote: Isn't that assuming the premise?
quote: This is self-contradictory. ------------------

quote: Dawkins, respectfully, has a tendency to anthropomorphize chemistry.
quote: The 'information' in DNA isn't about how to survive. It isn't about anything, any more than any other molecule is 'about' the chemical reactions/combinations it undergoes or can undergo. DNA isn't trying to survive. It survives as a side effect of what it does-- react with other chemicals. Its survival is de facto, not intentional. It is wrong to ascribe volition to molecules. To more directly answer the question, the species doesn't give a crap about surviving. The species is not a thing cabable of caring. 'Species' is not a thing at all. It is an abstraction. We talk about species as if they were things in just the way that the law in the US treats corporation as if they were people.
quote: Again, not really. NS is a label we put on a process. Some animals reproduce more successfully than others, for various reasons, but it is not teleological. Animals don't struggle to survive, they just do what they do. Survival is a side effect. The appearance of struggle is an abstraction. Think of a river flowing through a rocky canyon. The water is whipped into rapids, eddies, etc. It appears to be struggling through the canyon, but it isn't. There is no real attempt to do anything. The water just obeys the forces pressing on it.
quote: No. Because there is no intent.
quote: This is exactly why the example is relevant. Show me a strand of DNA that does something other than follow its inhernet chemical properties.
quote: Of course not. Chemistry isn't teleological. Chemicals don't try to get from anywhere to anywhere. Chemicals just react.
quote: I'm not. DNA is a molecule. It behaves like any other molecule. Where does DNA not follow basic chemical laws?
quote: Only in the absence of an energy supply.
quote: If I were interested in chemical equilibrium I'd look for a real source.
quote: You are missing the point. If we look at results, and infer a motive based on the results, then we must consider the most common result-- extinction. That is the flaw in the approach. You can pick one result. I can pick another, and frankly, mine is the better choice. An organisms instinct are irrelevant when trying to infer from results. It is a different line of reasoning altogether.
quote: Yes, but you are still applying volition inappropriately. The argument sounds pretty good when animals like mammals. But it becomes less convincing when talking about insects. Much less convincing when discussing bacteria. And kinda silly when the subject is a virus. Do you claim a virus 'wants' to survive? It 'want to' even though it has no brain, or even any organs at all.
quote: Do viruses have instincts? Or do the molecules just do what they do? You should really consider cleaning up your terminology.
quote: This is begging the question. And circular. If you take a strand of DNA and parse it to find syntax, etc. you can't turn around and say these things caused to DNA. If you parse a line of code to find syntax, you can't infer that the syntax caused the code.
quote: It is irrelevant. My computer produces heat. I cannot infer that it is supposed to produce heat, noise, and electric bills. Likewise, DNA reacts with other chemicals and produces a myriad of effects, but you cannot infer that these effects are its raison d'etre.
quote: But you haven't told me the equation. Dealing strictly with DNA, what is the equation it is supposed to solve?
quote: What? What claim? An example of what, exactly?
quote: ... of what?
quote: No we can't, for reasons I've already stated.
quote: That is not a problem. Any access to information we have is material and we'd recognize the technology.
quote: I'd say there would be a pretty good chance that we wouldn't recognize it as having been built, unless or until people started noticing things like tool marks or materials that do not occur in nature. Thus, we would, if we recognized it at all, recognize it by analyzing patterns.
quote: Do I?
quote: Wrong. Suprisingly convincing arrowheads can be made by pouring water over hot flint. These are just as complex-- more so, probably-- than hand-made arrowheads. The first stone tools known are so simple that it hard to tell them from ordinary rocks. They are distinguished by repetitive patterns, not by any high level of complexity.
[quote]The DNA possesses all of these qualities.[quote]
What qualities? It is not periodic, and it is very complex? So is a pile of sand. The most complex things are entirely random.
quote: Because the inference is invalid.
quote: No it doesn't. SETI uses pattern recognition. SETI is a search for recognizable patterns in space noise. The most complicated thing is the noise itself.
quote: It is with DNA. The 'information' and the chemistry are one and the same. You can't alter the chemicals without altering the information. Nor can you change the medium and have the DNA function. It is not like copying from hard drive to cd.
quote: Not with DNA. You cannot seperate the 'information' from the medium.
quote: It doesn't work. Random is very complex.
quote: Wrong. I didn't use any of Gitt's definitions. Gitt is a git.
quote: I have dealt with this objection.
quote: Still don't know what you want with this one.
quote: Your first two sentences are an assumption. In fact, they are a statement of what you wish to prove, so they can't also be an objection. The next two sentences constitute a straw man. Words, books, letters, etc. do not react with their environments in the way that molecules do.
quote: We determined that did we? I'd say that information is an abstraction and not really a thing at all.
quote: Chemicals organize without the aid of any mechanism beyond their own chemical properties. Crystals, for example.
quote: This would be a straw man for the sames reasons that the book example was a straw man. ------------------

quote: This is a fallacy known as an appeal to authority. The problem is that it doesn't matter who said what. What matters is the argument.
quote: It is. You may not realize this but you are also jsut some guy on the internet. Perhaps I'll refuse to take your ideas seriously for that reason and that alone? Sound like a good plan?
quote: "The genetic book of the dead" is chapter ten in "Unweaving the Rainbow." Why do you talk about who you believe, rather than what and why you believe?
quote: Hang on, now. I knew something was wrong with this objection but I had to read through it a few times and crawl into bed for it to hit me. If you allow what you allowed just previously...
dillan writes: I will (against my better judgement) momentarily agree with you that it may be impossible to know whether DNA's survival was originally created for the purpose of life (creation), or that it is a random side effect of chemical reactions (evolution). ... then you can no longer claim that DNA fits Gitt's definitions. Allowing that we cannot know whether DNA was created for a purpose, means that we cannot know that it meets Gitt's fifth element-- apobetics. In fact, it seems to me that this consideration will make any argument fatally circular. If these five elements are necessary conditions for identifying information, then you need external support for each of the five elements. You can't infer from some to all. Checkmate.
quote: No. I don't see. The bonds between the atoms of DNA follow the same rules as any other molecule.
quote: DNA is not remotely like ink on paper.
quote: You are talking about one and the same thing with a DNA molecule. It is more like a clock than a computer. The springs and gears are material to the information it carries-- a measure of time. You cannot print it to paper or you destroy the information-- the clock won't work. Likewise, you can't copy DNA to any other molecule and have it do the same thing the original does. You cannot replace the atoms and have it work.
quote: You've not answered the question. What does DNA do that does not conform to normal everday rules of chemistry? You repeatedly claim that DNA is special, yet you cannot tell what it does that is special?
quote: Are you joking? DNA is a mess.
quote: The floppy disk analogy is so bad it makes me weep. I believe the problems have been pointed out to you.
quote: Why are you quoting something about violating the second law? I said nothing about violating the second law. With an energy supply, you can have local increases of complexity. Without an energy supply, the system winds down until it reaches equilibrium. Nothing here violates the second law. This John Ross wouldn't be the lawyer would he?
quote: That's just it. Do bacteria need? Do viruses need? Like I said, it is an improper application of the idea of voliton.
quote: React with other atoms and molecules according to some basic rules, all of which have to do with very physical and natural forces. What do you think they do?
quote: Begging the question.
quote: The two are very different. The analogy is terrible.
quote: That is exactly right. This, however, cuts the legs right out from under you. You can't infer design from here.
quote: Did I not just answer that? We recognize the results of our own behavior. We know what stone tools do the bone. We know what teeth do to bone. The marks on a bone look like stone tool marks so we conclude that they were made by a human and, by extension, by an intelligent being. SETI was similar, but with math. We know what patterns our mathematics produce, etc.
quote: You have got to be joking? Imagining an imaginary chemistry with imaginary laws is your response? The fact is that you would have to imagine the exact same chemistry that we have now in order to get the SAME information in the molecule. That is because the molecular bonds cannot be ignored. They are part and parcel of the molecule. You could get a DIFFERENT life, perhaps, but that is not the same information is it?
quote: The book analogy is ridiculous. Manipulating ink on paper is nothing like manipulating the structure of a DNA molecule.
quote: Sure, but that isn't the point is it? The correct question should be "Can one get the same reactions-- the same information-- with other amino acids?" Not likely. I really have no idea what the point was of the lengthy Contact discourse.
quote: But you miss the importance of it. You can put ink on paper in any configuration you choose, because all the ink sticks to all the bits of paper equally. All the bits of DNA do not stick to all other bits equally. That is a big difference.
quote: The researcher says the TREATMENT is identical. He is not trying to infer design. That is a very big difference. You, however, are trying to infer design. ------------------

Lol... give me a few months and I don't understand my own code, and I write simple stuff-- nothing professional.
