Kuresu:
What I'd like to see, I guess, is a compilation of current abiogenesis information--what we do know about DNA replication and creation.
My apologies Kuresus for the cynicism dripping from the words of my post you have so brought to this table. I will endeavor to discuss the matter without prejudice.
I would like to defer to a man who worked in the field of abiogenesis for many years before that 'term' was coined . He spent time at NASA Ames Research Center (among many other labs) in search of the evidence for his and his co-author's own textbook on the subject.
I understand what he is saying; part of which, is a refutation of the often promoted idea, that 'abiogenesis' is not the same thing as evolution, or more specifically, 'natural selection'. It is all based upon cause and effect within the natural laws. It is ultimately the very same thing, only on another level (or dimension) of scale.
He makes it clear, that 'abiogenesis' is equal to 'biochemical predestination' (or chemical evolution). And he explains very openly why he ultimately rejected the idea. At another point in the same source he says, "It just reached the intellectual breaking point sometime durring the end of the decade of the seventies".
Dean Kenyon - coauthor of textbook on theory of biochemical evolution, ”Biochemical Predestination’ 1969 / professor of biology (emeritus) San Fransisco State University
Kenyon on ”describing the complexity of a living cell’ [and the problems assopciated with the concept of abiogenesis].
“Back in the days of Charles Darwin, relatively little was known about the complexity (the enormous complexity) of the microscopic world -the microscopic aspects of living organisms. There was a view in the latter part of the nineteenth century that a living cell was essentially a featureless bag of enzymes; all, kind of in a true solution. Not much in the way of detailed three dimensional complexity.
But of course in the twentieth century, we’ve made enormous strides in understanding that that’s not the case at all. There is a very great degree of intricacy of architecture down in the cell units. So today, everybody understands about bits and bites, and so perhaps a useful illustration of the complexity of, say the DNA molecule, might be helpful.
You can calculate the number of bits contained in tightly packed DNA material that would fill one cubic millimeter of space as equaling 1.9 times 10 to the 18th power, bits ( or, 1,900,000,000,000,000,000). Now that number, is by many orders of magnitude, vastly greater than the storage capacity of the best supercomputing machines. Their storage capacity is far less, than the storage capacity in the DNA Molecule.
Now moreover, the DNA itself as it functions in a living cell has about one hundred different proteins involved with just its own functioning. And then you have these tens of thousands of other proteins in the living cell also involved. So we have now a picture of immense sub-microscopic complexity. And so no longer is it a reasonable proposition to think that simple chemical events could have any chance at all, to generate the kind of complexity we see in the very simplest living organisms.
So, we have not the slightest chance of a chemical evolutionary origin for even the simplest of cells, with the new knowledge that’s accumulated in this century.”

Kuresu:
tell me, is your only defense a nearly forty year old book that naturally ignores all modern research on the topic of abiogenesis? The argument is based off of data we had 40 years ago. Do you not think that new research has happened since then?
Take it easy there Pilgrim...
The book you are talking about is a textbook on the subject of Abiogenesis. In it, Kenyon and Gary Steinman posited the theory that life was biochemically predestined by nothing more than chemical laws.
It is Kenyon himself who gave up the idea because of the enormous complexities found since then. So it is Kenyon who, based on the current knowledge you are speaking of to this day, refutes the concept of Abiogeneisis.
I think the basic concept is this (but this is my understanding and not Kenyon's per se):
The more complex the system, the less attributable by chance it can be. With biology, we have the most complex system in the known universe without peer. Not to mention it is sitting in a system which it is dependant upon to exist. In fact we have layer upon layer of systems from the atomic to the galactic. Are any of them unnecessary for life?
Probabilities being what they are, all of that is based upon what we do know. Perhaps new evidence will come in, is that what you are looking for?
Do you wish to refute these ideas, or is this thread only looking for pro-evidence of abiogenesis?
All I did... was show that Kenyon (who was not a 'biased and devious prejudicial Christian like me' at the time of his rejection of abiogenesis. And may still not be... I don't know) rejected his own theory because of the new knowledge you are talking about.
And as biology shows itself to be more and more complex (not less) the problem for abiogenesis only gets worse Kuresu... not better.
In my opinion (as valueless as it may be to you and the other 'optimists') all the new evidence works against abiogenesis, not for it. Optimism abounds yes... but imagination is not equal to reality.
Reality has no equal...
As C.S. Lewis said somewhere, 'we could never have thought of it'.

Thor:
This is basically saying "It's too complex, therefore it couldn't have evolved". No reason is given other than it being 'too complex'. This is nothing more than the famous argument from incredulity. Until someone can determine a point where something becomes 'complex' and a substantial reason is put forth as to why 'chemical evolution' cannot produce something of such 'complexity', it is a pretty empty argument.
Kenyon put forth the notion that amino acids are attracted to each other by mere natural laws. What he actually found durring the testing of this theory, was that amino acids do not have the ability to order themselves into any biologically meaningful sequences. So neither He, nor I, am sugessting that it is not posible. All we can say is that the conditions and laws needed for abiogenesis have never been observed.
There is another rub that is often overlooked. The scientists who are manipulating matter and supposed conditions in the lab, are by definition 'intelligent agents'. If they are able to produce some burnt slime after zapping a chemical soup (while making massive and unverifiable assumptions about theoretical atmospheric conditions on the early earth), can they really say that 'such an experiment proves that it is possible without intelligent guidance'?
As for it being too simple. It is simple Thor. There is no evidence for abiogenesis. It is a totally faith based concept. Kenyon proposed a theory on how it might have occured. He was a very ambitious 'evolutionary biologist'. Turned out he was wrong. At least he has the gumption to admit it.
Complexitiy does not mean abiogenesis is not possible. I only ask for you to show me how it is?
Let me ask you this... Could an automobile have evolved without intelligent agents designing it? It is nowhere near as complex as biology. In fact it's parts can be reduced very easily. I've done a little wrenching on cars in my day. You don't need a degree in medicine. All man made things break down into simpler and simpler parts. God's creation only get's more complex as we look deeper into the layers of dependancy within the system.
So what is easier to believe? If we would not expect to find an old car buried in the mud and immediately conclude it is natural, then why do we so with life?
Forget theory and inuendo... where are the laws and evidence to explain these things with the observations we do have?
Do they exist?

Nonsense Rob. Of course there is evidence for abiogenesis. There was a time when there were no living things on earth. There are now living things on earth. Therefore abiogenesis happened.
Are you implying very cleverly that it would be incredulous to think otherwise?
So... let me get this straight...
You are also saying that Kenyons arguments are not credible because they are mere incredulity in the final assesment.
Thanks jar! I needed that today...

Dr.A:
If we would not expect to find an old car buried in the mud and immediately conclude it is SUPERnatural, then why do we so with life?
But we would conclude that the old car came into being supernaturally. And rightly so...
I think one trap we too often fall into is thinking of the supernatural as 'unnatural'. That is not what supernatural means. Just like something super-rational (like the scriptures) is not 'irrational'.
The only difference between the natural and unnatural for the context of this argument is 'mind' or 'intelligence'.
I suspect we will not even be able to agree upon that...
The equivilant comparison is mindlessness (randomness or chaos) vs. intelligence (order and harmony).
Those are the terms I am speaking in when I say supernatural vs natural. Random events do not give you order...
Kuresu, agreed or not, are you listening?

Re: statements of fact.
jar:
No, I am saying it would be false and a sign of ignorance and dishonesty to say otherwise.
That's called deferring to common sense... but who's common sense?
Bertrand Russel used the same argument when asked to explain the origin of the universe. "It's just there!", He said...
Well, why can't I say that about God? He's just there!"
Your double standards are mezmerizing...
jar:
The fact is that the evidence shows there was a time when there was no living things on earth. We can see that there are living things on earth now. Therefore, abiogenesis happened. Like Evolution, Abiogenesis is a Fact. We are still working to develop a Theory of Abiogenesis that explains how it happened as well as the Theory of Evolution explains the life we see about us, but that Abiogenesis happened is not an issue.
Ok fine!
It is obvious life is here... I'll agree with you there. How it came into being is another matter. Was it intelligently guided or not?
You said in one of your replies that you believe God created all of it. So is that not an intelligent design irrespective of any deficiencies you may perceive in the system?
Seems to me that the issue is one of how life came into being. You also indicated this same idea.
If we agree on that, then however God God created life, it is not unnatural but supernatural. And it is only supernatural relative to our current understanding. The real solution supercedes our current understanding.
What intrigues me, is that the more we know, the more incredible it becomes. The more awesome and miraculous it appears even if we do understand it more.

Dr. A:
Supernatural: supervening the laws of nature.
Artificial: created by intelligent processes.
That's what the words mean, you don't get to change the English language by fiat.
Intelligence is artificial?
I don't know about that, but it kinda confirms my point that human life is very unusual (almost alien) to the rest of the creation. There is something very unique about us.
We're supernatural! But here we are...
But this is encouraging. you're saying that words do have an objective meaning and that I cannot interpret by what they mean to me?
Websters:
Artificial 1: produced by art rather than nature; also : made by humans to immitate nature 2 : not genuine : FEIGNED
So 'man-made' is artificial. How bout God-made? God, who is the supernature (the canvass upon all else hangs.
Dr.A:
If you think that "mindlessness" is the same as "randomness or chaos" then you know nothing of physics, and if you think that "intelligence" is the same as "order and harmony" then you know little of the way our poor species conducts its daily affairs.
Who said that we were intelligent?
You are however paying a compliment to order and harmony with your statement.

Re: Remedial reading?
NosyNed:
How on earth could you get what you said from DrA's definition? I'd like to see a detailed explanation. As it is this little exchange explains why it is impossible to talk with you. You can't read.
I could just as easily say the same with some of you. The fact is all of us can read. It is frustrating though. At least we agree upon that. We are speaking different languages conceptually (or spiritually) IMO. That aside, let me explain...
Dr.A.:
Artificial: created by intelligent processes.
How else should I interpret this definition?
If that which is 'artificial' (forgery) is created by intelligence, then that which is real (not artificial) must arrive from unintelligent processes.
So, this definition is actually defining intelligence as phony.
Now in the biblical sense this is true of you and I. But man's intelligence is not God's. God's intelligence is not artificial.
You may not agree, and it is certainly now veering way off the topic. But that is where I am coming from. How we can communicate with such a different ontic referent for our assum

No. It is a personal belief and has NOTHING to do with the issue of a Theory of Abiogenesis or of the fact that Abiogenesis happened.So far all of the evidence is that only natural methods will be involved.
Is that the only evidence you are looking for?
Do you expect that unnatural methods would be involved?

Artificial
Websters Definition / Artificial 2 : not genuine : feigned
Dr.A.:
I'm saying that they have a conventional meaning
Now that is precisely what I intend to find out in another thread.
Ok Ok... seriously... I know this is geting very muddled and I apologize for the mess.
You missed my point thanks to my poor conversion of word to concept. Let me try again.
Dr.A.:
No. The manufactured products of intelligence are artificial.
Ok, so that which is unmanufactured is genuine?
If so, does the convention manufacture artificial or genuine language with their so-called intelligence?
Dr.A.:
if you "reinterpret" them arbitrarily then you will be unable to communicate with English-speaking people. A point amply proven by this thread.
I disagree in kind.
I may be unable to communicate with the convention, and crucified for standing up to its manufacturing of truth.
I stand for the genuine article Himself.

I assume there was aa Artificial 1 entry in the Websters dictionary. May be that`s the one everybody else in this thread is using. (A clear case of equivocation). Now, I find it really hard to believe you could be that desengenious, should I assume you are simply being facetious?
No... If you go back you will see my listing of this definition previously.
But I think Kuresus is right. This has gotten far away from the original topic. I don't even remember how we got to this point. I'll have to re-read.
My apologies for any misunderstandings.

Kuresu:
just what the heck does "artificial" really have to do with abiogenesis, the topic?
might I suggest you all staying on abiogenesis?
I agree...
Even so, jar has already culminated the entire subject into a neat little package. It is better known as an A Priori assumption that since life is now here, we know abiogenesis happened.
If you are looking for evidence, I am with you. I am waiting.
