Re: metaphysical...
Kuresu:
An organism is biotic by definition.
So de novo is the only way to go huh?
Because natural selection would require replication and autonomy.
And if autonomy and replication are not prerequisites for 'organism' then what is?

Re: metaphysical...
jar:
Did you read what I posted? Abiogenesis is a conclusion. We see life. We see a period before that when there is no sign of life.
The conclusion is "Life happened."
Haven't we been here before? Sounds like incredulity to me!
Why don't you let the evidence speak for how it got here? How can you presuppose that there is no intelligent design?

Re: metaphysical...
It doesn't matter if god did it (after all, God used dust, which isn't alive, to make man) or if it happened by natural causes. It doesn't matter if life was seeded my aliens. All abiogenesis means is life from non-life.
I like it!
But I'm afraid not...
Main Entry: abio·gen·e·sis
Pronunciation: "A-"bI-O-'je-n&-s&s
Function: noun
Etymology: New Latin, from 2a- + bio- + Latin genesis
: the supposed spontaneous origination of living organisms directly from lifeless matter
It assumes a material cause before the evidence has spoken...

Re: metaphysical...
kuresu:
How would the intelligent designer make anything different?
If he was creating life, he'd have to make it out of things that aren't alive.
Or are you suggesting that life has existed from the very beginning?
He would create them whole. No evolution needed.

Actually, if life was created by God, then it came from God not non-life.

Re: metaphysical...
Kuresu:
How would you determine he created them "whole"? What is "whole"?
How do you determine that he stepped in? What are his marks? How are they identifiable from the chemical and physical laws we know?
You're offering very poor arguments. No substance, no logic, and all assertion.
And how did evolution enter the argument? This is supposed to be about creating life, right? Not about life evolving, right? Can't you stay on topic in your own thread?
Abiogenesis is also the evolution of life from mere chemicals in the material stance. That is why it is also known as chemical evolution.
His marks would be the digital code that is analogous to other systems that are emperically shown to arise from intelligence. The high information content that is specified, non repeating, and extremely complex. We don't see that in the physical laws. They only repeat simple patterns.

Re: metaphysical...
Kuresu:
Since you don't know, it's hopelessly metaphysical, right?
It's just what the evidence shows. Irreducibly complex organisms that self assemble based upon a quaternary digital code which contains all of the instructions to build an organism.
20 For since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that men are without excuse. 21 For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. 22 Although they claimed to be wise, they became fools...
Kuresu:
Why would life come from god? Why couldn't he make it with the materials around him (see: genesis, the creation of adam)?
If you don't know, isn't it all metaphysical bullshit?
You have to understand that he is energy (which is matter). And I have the Biblical passages to prove it, but it'd have to be in another thread.

Converting raw energy into biological energy
Summation
As I asked and stated upthread (though not so nicely):
Do we have one shred of evidence for a prebiotic organism or self replicating system?
Theory is not evidence...
Do we have any evidence in the real world; emperical, ie. the fossil record, or discovered anywhere, or for any form of autonomous cycle?
I ask, because there is an earthload of evidence for biological organisms and how they function. And they're not made the in the way these masses of theoretical research assume and predict that prebiotic organisms might have been made.
What good is a 'scientific' prediction (or theory) that cannot be tested against evidence?
As for biological life, we don't have to say, "if these biological organisms were able to synthsise ATP, adenine, or manufacture other biological structures or enzymes etc, then perhaps it was a result of a, b, and c." No, we don't have to say that, because they actually exist! And they do synthesize ATP, adenine, and manufacture other biological structures, and we have evidence of that. And it's proven science. It's not tentative or theoretical.
Science is a search for proof in the natural world. We start with theory and evidence or vice versa. We then seek to find a match between the two. All abiogenesis has is theory; there is no evidence and no match.
As Richard Lewontin says plainly, 'Evolution is hopelessly metaphysical'. And he is as staunch an evolutionist and materialist as there is.
Kuresu correctly pointed out that 'prebiotic organisms' are a contradiction in terms. Yet in terms of abiogenesis, that is precisely what prebiotic chemists are assuming existed and try to reconstruct as precusors to actual and emperical organisms. They either have to admit de novo formation of life which Orgel concedes would be a near miracle, or speculate on the contradictory notion of self organizational ribozymes that allowed for the natural selection of higher states of order and eventual organisms. But that is precisely what an organism is; a self replicating autonomous cycle.
Scientists interested in the origins of life seem to divide neatly into two classes. The first, usually but not always molecular biologists, believe that RNA must have been the first replicating molecule and that chemists are exaggerating the difficulties of nucleotide synthesis...The second group of scientists are much more pessimistic. They believe that the de novo appearance of oligonucleotides on the primitive earth would have been a near miracle. (The authors subscribe to this latter view). Time will tell which is correct.
This discussion... has, in a sense, focused on a straw man; the myth of a self-replicating RNA molecule that arose de novo from a soup of random polynucleotides. Not only is such a notion unrealistic in light of our current understanding of prebiotic chemistry, but it should strain the credulity of even an optimist's view of RNA's catalytic potential...Without evolution it appears unlikely that a self replicating ribozyme could arise, but without some form of self-replication there is no way to conduct an evolutionary search for the first, primitive self-replicating ribozyme.
(source / Darwin's Black Box Chapter 8 footnote 5 / Joyce, G.F., and Orgel, L.E. (1993) "Prospects for Understanding the origin of the RNA World" in The RNA world, ed. R.F. Gesteland and J.F. Atkins, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, p. 19, 13.)
Molbiogirl, in an attempt to show evidence of these modern pre-organisms, referred organisms that use sulfer as a means of respiriation to produce ATP. But whether in the presence of oxygen or not, organisms designed for using sulfer as an electron receptor instead of oxygen, would do so regardless of whether oxygen is present, just as organisms designed to use oxygen as an electron receptor would do so even in the presence of sulfer. Different organisms have different ways to synthesize ATP.
The point is... that all of them use ATP as the energy currency, and this poses an vexing problem for prebiotic chemists. The necessity of adenine and the inability to account for it in any biologically plausible or relevant environment, means we must defer to the actual evidence; that these organisms catalyze adenine and other biologically necessary molecules themselves with the help of enzymes that are in turn manufactured from the coding for their sequence in the DNA, which is in turn an energy dependant process needing ATP for it's functioning.
The other attempts to solve this problem (that were not addressed in this debate) such as symbiosis and complexity theory have their own immediate problems.
Symbiosis for example, actually requires two autonomous self replicating organisms that combine into one modern higher form. But it does not solve the immediate problem of the arrival of the two systems to begin with. It's bad enough a problem with one. Symbiosis also assumes that the systems, as seen in a symbiotic relationship today, have actually lost many of the functions that once made them autonomous. So, as for mitocondria, they would have to have been more complex than the relatively simple form we see today to remain autonomous.
Complexity theory is a mathematical construct created by intelligence and is tested exclusively using computer technology that is also created by intelligence.
The vaguness of complexity, though has started to turn off early boosters of the theory. Scientific American ran favoralbe articles over a number of years (one authored by Kuaffman himself). On the cover, however, the June 1995 issue asked, "Is Complexity a Sham?" Inside was an article entitled "From complexity to Perplexity" that noted the following:
Artificial life, a major subfield of complexity studies, is "fact-free science," according to one critic. But it accels at generating computer graphics.
( Behe / 'Darwins Black Box', pg. 191)
It's a chicken and egg paradox folks; we can't have one without the other. To get the molecules necessary for biological life, we need the processes of biological life that catalyze them. And to get biological life, we need the molecules necessary for biological life.
The only self replicating processes we see are called organisms. As Joyce and Orgel conceded long ago, the paradox of evolution without self replication leaves the models, postulates, and research for a self replicating robozyme a product of myth. It's de novo or nothing. It's irreducibly complex. Makes me wonder why they keep looking in the same direction since they are so frank about the problems.
It is just as Dean Kenyon and Stephen Myer have shown in their most excellent contributions to the video clip you can all watch here: Abiogenesis
Just scroll down to the man writing on the chaulkboard and click the play button on the YouTube link. It is clip 5. For the full context you should watch clip 6 which can be acessed in the menu that will pop up when the clip is finished.
And for complete context... watch all 7 clips.
Publish or Perish?
As for the questions of others above as to the explanatory power of Intelligent design and the proofs they offer, we'll have to have another thread. This thread is the search for answers to the theory of abiogenesis with material evidence.
And the verdict... there are none.
Perish!

Embarrassing!
With all due respect to Percy and his worldview...
What I have focused on is the known facts and evidence. It is the positive aspects of the natural world evidence that debunk prebiotic organisms. Not on the grounds that there is missing evidence; but on the grounds that what evidence there is, points to design.
If Percy's arguments were true, he could just as easily say that 'I am trying to prove a negative by saying we have not found the evidence that the pink unicorn created the universe' and that therefore such evidence does not exist.
I never said (nor has any intelligent creationist) that there is evidence that some things could never have come about naturally. Clearly the evidence shows that some things do come about naturally. But other evidence also points to design in the field of biology. That evidence belongs in another thread. For those interested in learning more in terms of the evidence for design, you might start here: Abiogenesis The YouTube link of Dean Kenyon near the center of the page is compelling.
I never said there is no evidence... I only asked to be given some.

Re: Embarrassing!
Rob:

Archer: So much for the supernatural designer--!
How does evidence debunking the myth of chemical evolution exclude God?
All it means is that life appeared fully formed. Or as Orgel said, 'the de novo appearance of oligonucleotides on the primitive earth would have been a near miracle'.
Slow down Archer... it's difficult to maintain perspective when we get this deep.
Here's the full quote:

Re: My summary.
No no no Chiroptera... Ringo summarized it far less words than you:
He has failed to demonstrate any fundamental obstacle.
Listen to Behe's analogy and the punchline left out by most critics of it:
Suppose you were a groundhog sitting by the side of a road several hundred times wider than the Schuylkill Expressway. There are a thousand lanes going east and a thousand lanes going west, each filled with trucks, sports cars, and minivans doing the speed limit. Your groundhog sweetheart is on the other side, inviting you to come over. You notice that the remains of your rivals in love are mostly in lane one, with some in lane two, and a few dotted out to lanes three and four; there are none beyond that. Furthermore, the romantic rule is that you must keep your eyes closed during the journey...
... Like a groundhog trying to cross a thousand-lane, there is no absolute barrier to putting together some biochemical systems gradually. But the opportunities to go wrong are overwhelming.
And... this thread is about the search for evidence of prebiotic organisms (a contradiction in terms) and key in that search is an organism that can directly utilize energy without converting it to ATP.
Got any?

In fact, the evidence that has been presented in this thread shows quite well that it is entirely possible that the energy conversion processes in the modern cell could have developed naturalistically.
And Santa Claus might be real too... after all you can't prve a negative.

Re: My summary.
Chiroptera:
Even if the thread's attempted point was accurate, that we have absolutely no knowledge of how the natural development of the cell is possible, that still leaves us with no way to conclude the existence of an intelligent designer of any sort. Any hypothesis requires external evidence to support it before it becomes a contender. Without any evidence that such an intelligent designer exists, then it is not an option for serious consideration (at least not beyond an attempt to see if positive evidence can be found).
Thank you for agreeing that the point was established. That was the goal of this thread. It will be the purpose of another thread to establish the evidence that is available for design.
It was never this thread's purpose to do that. And it is not an argument against this threads goal.
One thing at a time Chiroptera... we have established the one... now we can move on to the other.
