Interesting answer, but please:

b. why did you assume, only 4 aces?
c. why did you assume, each card is unique?
d. why did you assume, order is unimportant? (perhaps your being to generous here)
e. why did you assume, being dealt 4 aces first up? If you were playing stud poker, the answer would be considerable less!

chance sits down at the table with deadlock there is a sum of money 9philispophic position) in the pot. Each player has $1000 (world view) in starting chips.

Yes, I Know because abiogenesis does not have the rules of your hypothetical game, the rules of abiogenesis are the laws of chemistry and probability, and unless you show me a new law that I don´t know your argument is flawed.


Sorry deadlock, but your evading the question, please explain why you made the assumptions, listed ‘a’ through to ‘e’.

The rules are simple the “laws of chemistry” are me handing out the cards to you, no cheating, no slight of hand. But chemistry is a very big subject, which chemicals shall I choose, how many decks are available, are the cards unique, are there more in one place than another, do I deal them today, in an hours time, or in a decades time? Non of this has been decided, there are no rules I have to follow, other than deal!

Re.a This sentence makes no sense to me. What has entropy got to do with anything regarding environments?

Deadlock>
Of Course it has.If an environment is completelly isolated it will end in a cold death by entropy.Abiogenesis cannot happen in an isolated system, it needs source of energy and chemicals.


This is just meaningless, how is a volcanic vent affected by this? If such a vent lasted for a million years and it was only required for 100 years to perform ‘it’s bit’ re abiogenesis, entropy can go and “jump in the lake”.

Environments can be ‘isolated’ without being ‘vacuum sealed away from the rest of the word, you know. A cave is an isolated environment with respect to it receiving no light from the sun, yet air, and water can circulate through them.

I found in the internet a good text that clarifies how the experiences of abiogenesis are very artificial.

Origin of Life Experiments and Investigator Interference

Investigator interference will now be summarized. Investigators do not have 5 billion years to conduct origin of life experiments, so some interference is necessary.

Interference Strategy #1: Eliminate the Undesirable Chemicals

If chemical A and chemical B react to form chemical P, then this chemical reaction can be written as A+B—> P. Suppose that Miller’s water trap contains 3 chemicals, A, B and C. The possible reactions involving the chemicals are as follows: A + B–>P and A +C->D.

Unfortunately, the second reaction is favored. So after a few days all of the chemicals in the flask are D, but the researcher desires chemical P. So instead of using the contents of the flask to create P, he orders A and B from his chemical supplier. He mixes these two chemicals while applying heat, and the product is P. This process is how organic chemists make chemicals. They control the chemicals that they start with, and this influences the products that they get. Applying this technique to origin of life scenarios is questionable because it is not clear how nature can exclude the undesirable chemicals.

One of the functions that enzymes perform is to eliminate undesired reactions. They accomplish this by speeding up the desired reactions. When investigators manipulate the chemicals in their system to create a desired product, they are mimicking this particular mode of enzyme action. They are using their knowledge of chemistry because the required molecular knowledge is not present in the system.

Examples of cross reaction elimination:

• Fox’s thermal proteins. He did not include carboxylic acids or other organic components (like aldehydes) that might terminate a growing protein chain.

• The most extreme examples of cross reaction elimination involve RNA. The reason is that ribose is included freely, but no amino acids are included. This is not a plausible condition. Amino acids react very quickly with sugars like ribose to create very long chain polymers. Anyone who has baked cookies or toasted a piece of bread is familiar with this reaction. Browning is caused when amino acids (especially lysine) react with sugar. This reaction would make any sugar present in the primordial soup unavailable for RNA formation.

Interference Strategy #2: Concentrating Volatile Chemicals

Concentrated formaldehyde is critical for the synthesis of ribose. Concentrated hydrogen cyanide and ammonia are critical for the synthesis of adenine. It is not clear how these chemicals could ever be present in high concentrations on the early earth.How does one concentrate a chemical that boils at sub-freezing temperatures in a small puddle? This is a difficult problem.

Interference Strategy #3: The Use of Condensation Agents or Activated Monomers

Condensation agents help form all of the bonds that are necessary in biological precursors, whether RNA or protein. Condensation agents remove water and by doing so promote the formation of large biological molecules. Condensation agents were discussed for proteins, but they have also been used to successfully join RNA nucleotides into short chains. RNA synthesis usually just skips this step, and instead researchers usually just add an activated monomer like impA, impG, impC, or impU.

There are no plausible synthesis mechanisms for the condensation agents or the activated monomers. If they are created in Miller’s spark experiment or if they exist in meteorites, then the amount present is minuscule. How some investigators can add these chemicals in abundance to reactions, and still think that they are modeling plausible prebiotic conditions is certainly not clear.

Nevertheless, the motivation for using these techniques is clear. Without these techniques, the biological precursors are limited to a size that is too small to be biologically active.Given that condensation agents and activated monomers are often coupled with carefully timed washes designed to grow the protein or RNA molecule.

Interference Strategy #4: Controlling the Energy Sources

In most experiments, destructive energy sources are eliminated by the investigator. For example, if the trap in Miller’s spark chamber is illuminated with UV light, many of the products will be destroyed.

Interference Strategy #5: Substituting Human Knowledge

This is the most subtle form of interference, and the most common. In systems that lack the required molecular knowledge, it is very easy for researchers to unintentionally add knowledge to the system through the design of their experiment.

The carefully controlled sequential washes that accompany many RNA and protein chain elongation experiments are a perfect example. Often a growing RNA or protein molecule is attached to a stationary substrate, activated nucleotides or amino acids are added, and a rinse is applied after the desired chemical bond forms. This form of interference is present in most prebiotic experiments, and sometimes it goes unnoticed.

Conclusion:

The goal was to show that the precursors to life whether RNA or proteins are extremely difficult to create. Maybe one or two such molecules are expected given optimal conditions and 5 billion years. The design inference based on this conclusion alone is very strong. If the entire ocean is packed tight with either proteins or RNA, then the odds that one of the molecules can self replicate is still zero. Several thousand bits of knowledge are required, and zero tries (or almost zero) will never allow chance to create this much knowledge.

Many investigators researching the origin of life are disappointed with their progress, and this shows in the scientific literature. Today, it is acceptable to publish an article that is critical of the origin of life paradigm as such articles do get published.

Any publication suggesting the possibility of design is either rejected or starts a witch hunt in which the editor who approves the article is the target. The first step in any scientific revolution is to realize that there is a problem with the current theory, and for many scientists this realization has already taken place. Joyce and Orgel summarize the situation as follows:
“In our initial discussion of the RNA World we will accept The Molecular Biologist’s Dream: “Once upon a time there was a prebiotic pool of Beta-D-nucelotides . . . We will now consider what would have to happen to make the dream come true. This discussion triggers the Prebiotic Chemist’s Nightmare: how to make any kind of self replication system form the intractable mixtures that are formed in the experiments designed to simulate the chemistry of the primitive earth.”

Because it has been done many lab tests trying to build functional pepitides.One of the more important experiments concerning the origin of life was performed by Keefe and Szostak.The authors of this paper in Nature searched six trillion random peptides each composed of 80 amino acids. They were looking for a sequence that could bind the chemical, ATP. They found only four sequences!!! in this large pool with ATP binding activity.
deadlock
The Lie of Self-Replicating Pepitide

In 1996, an article was published in Nature in which David Lee reports to have found a self replicating peptide.The title of the article is appropriately “A Self Replicating Peptide.” Unfortunately, the investigator interference required for self replication is perhaps the most extreme in the history of origins research. This experiment is not even relevant to the origin of life.

The peptide of interest contains 32 amino acids. The sequence is as follows:

arg-met-lys-gln-lys-glu-glu-lys-val-tyr-glu-lys-lys-ser-lys-val-ala-
cys-leu-glu-tyr-glu-val-ala-arg-leu-lys-lys-leu-val-gly-glu.


The peptide does not self replicate using amino acids. Instead it uses a pool of two peptides, one is 17 amino acids long and the other is 15 amino acids long. The amino acid sequences of these two peptides are shown below. Notice that if a peptide bond forms between ala (last amino acid on right in the peptide with 17 amino acids) and cys (first amino acid on left in the peptide with 15 amino acids) then a replica of the self replicating peptide results.

arg-met-lys-gln-lys-glu-glu-lys-val-tyr-glu-lys-lys-ser-lys-val-ala

cys-leu-glu-tyr-glu-val-ala-arg-leu-lys-lys-leu-val-gly-glu


Because the peptide with 32 amino acids facilitates the formation of this single peptide bond, Lee claims that this peptide can self replicate. But is this really true? To self replicate, this peptide requires a pool of two peptides. One of these peptides has the same amino acid sequence as the first 15 amino acids in the self replicating peptide, and the other has the same amino acid sequence as the next 17 amino acids. Where do these peptides come from? In this case, they are supplied by the investigator.

Due to the difficulties, peptides with more than six amino acids are expected to be very rare chemicals. Peptides composed of 15 to 17 amino acids will be much more scarce. Yet to self replicate, this peptide requires an abundant supply of both, and not just any peptide will do. One of these peptides must be identical to the first half of the self replicator, and the other peptide must be identical the second half of the self replicator.

This last requirement is particularly troublesome. Suppose the self replicator comes into contact with two random peptide chains. One is 15 amino acids long and the other is 17. How often will the two smaller peptides be an exact replica of the self replicator? Answer 1 time in every 4x10^41 tries (assuming that every amino acid has a 1 in 20 chance of occurring at each position). Given the low concentration of peptides in the primordial soup, the probability for such an encounter is zero.

The interference does not stop here. It is critical that the first amino acid in the peptide with 15 amino acids be a cysteine. Cysteine has chemical properties that facilitate peptide bond formation, and to make sure that the interference sets the record for the most ever, the alanine (last amino acid on right in the peptide with 17 amino acids) must be chemically altered to make it much more susceptible to attack by cysteine.

Finally, the self replicating peptide contains eight lysines. Lysine is instrumental in its self replication as its charge plays a role in aligning the two small peptides. Lysine is one of the amino acids that has yet to be synthesized under plausible prebiotic conditions. So even if lysine was present in the soup, its concentration would have been negligible.

Every possible strategy of interference is employed by this investigator to promote replication. This mixture of peptides has almost no chance of existing on the primitive earth. Even if it did, as soon as the supply of 15 and 17 amino acid peptides runs out, the replication stops. Despite all of this interference, the claim of self replication is not valid. Self replication involves a system that can duplicate all of its components. In this system, the self replicating peptide is supplied with one peptide containing 15 amino acids and one with 17 amino acids. A true self replicating molecule could generate these two smaller peptides from the amino acids in the primordial soup.

The authors of this paper tried to use dynamite to blow up the door , but the door withstood the blast and did not open. So the authors just said that it was open.

Proteins do not self replicate, and this explains why most scientists rejected the self replicating protein hypothesis in favor of the self replicating RNA hypothesis.

It´s not self-replicator because the only thing that it does is to catalyse the bond of two pre-existing half of itself.To be a true self-replicator it must make a copy of itself using free monomers and activate the link.

Origin of Life Experiments and Investigator Interference



from the artical:

QUOTE
Investigator interference will now be summarized. Investigators do not have 5 billion years to conduct origin of life experiments, so some interference is necessary.


Obviously!

QUOTE
Interference Strategy #1: Eliminate the Undesirable Chemicals

If chemical A and chemical B react to form chemical P, then this chemical reaction can be written as A+B—> P. Suppose that Miller’s water trap contains 3 chemicals, A, B and C. The possible reactions involving the chemicals are as follows: A + B–>P and A +C->D.

Unfortunately, the second reaction is favored. So after a few days all of the chemicals in the flask are D, but the researcher desires chemical P#1. So instead of using the contents of the flask to create P, he orders A and B from his chemical supplier. He mixes these two chemicals while applying heat, and the product is P. This process is how organic chemists make chemicals. They control the chemicals that they start with, and this influences the products that they get. Applying this technique to origin of life scenarios is questionable#2 because it is not clear how nature can exclude the undesirable#2 chemicals.

One of the functions that enzymes#4 perform is to eliminate undesired reactions#2. They accomplish this by speeding up the desired reactions. When investigators manipulate the chemicals in their system to create a desired product, they are mimicking this particular mode of enzyme action. They are using their knowledge of chemistry because the required molecular knowledge is not present in the system.

Examples of cross reaction elimination#4:

• Fox’s thermal proteins. He did not include carboxylic acids or other organic components (like aldehydes) that might terminate a growing protein chain#4.

• The most extreme examples of cross reaction elimination involve RNA. The reason is that ribose is included freely, but no amino acids are included. This is not a plausible condition#4. Amino acids react very quickly with sugars like ribose to create very long chain polymers#4. Anyone who has baked cookies or toasted a piece of bread is familiar with this reaction. Browning is caused when amino acids (especially lysine) react with sugar. This reaction would make any sugar present in the primordial soup unavailable for RNA formation#4.
(my inclusion of # numbers)

#1 – Assumption, researcher desires P
#2 – Assumption, undesirability re an unknown environment, and unknown process.
#3 – Misconception showing a principle is not proof of abiogenesis.
#4 – Misdirection, assuming current life process are applicable to the abiogenesis event.

From this point on I gave up, the entire post is saying “this wont work, because conditions NOW, for existing life systems or chemicals required for life, wont allow it” . Well obviously!!

The entire document is a straw man argument, completely obscuring what abiogenesis is proposing. The post tries to shoehorn abiogenesis into a jigsaw puzzle where every piece represents a currently required chemical for life, and life is created when the last piece is inserted (like building a watch). Assumption upon multiple assumption.

It’s a complete misrepresentation of abiogenesis.

How can you be arguing against a position if you don’t know what it is! Nevertheless, I propose this Wiki explanation as good as any (this also answeres your post #222):

Abiogenesis (Greek a-bio-genesis, "non biological origins") is, in its most general sense, the generation of life from non-living matter. Today the term is primarily used to refer to hypotheses about the chemical origin of life, such as from a primordial sea or in the vicinity of hydrothermal vents, and most probably through a number of intermediate steps, such as non-living but self-replicating molecules (biopoiesis). Abiogenesis remains a hypothesis, meaning it is the working assumption for scientists researching how life began. If it were proven false, then another line of thought would be used to modify or replace abiogenesis as a hypothesis. If test results provide sufficient support for acceptance, then that is the point at which it would become a theory.

Have you thought about what are you saying ? It´s difficult to believe that you are not seeing the silly argument you are using.

First of all I have nothing against the lab results itself.The only problem is that they must simulate true natural conditions if the goal of the experiment is to show that a specific phenomenon can occur in nature.Abiogenesis experiments didn´t fulfill That task.Second, an intelligent designer does not need to follow those requirements because an intelligent designer is not a naturalistic phenomenon.Intelligent Designer is a person using his intelligence to build something.So, if a human being can build life in lab then he will have proved that life can be created by an intelligent designer.

If you disagree, then please point out how a cell could be reduced to self-replicating autonomous units, or demonstrate how a cell could have evolved without resorting to vague undefined precursors that you cannot produce or demonstrate how they function.

If you agree that an amoeba could not be produced by a "single event', then you cannot rely on multiple smaller events unless you can show that each of these events produced some sort of autonomous self-replicating unit.

That's a convenient excuse that amounts to nothing less than a cop-out. You say we don't know what conditions of the ancient earth were. Fine. You are free to speculate whatever conditions you might suppose could have existed. Even though you cannot prove that there ever was a "primordial soup" or that whatever conditions you chose existed, you're theory would be taken seriously if it had any validity. The fact is, regardless of the scenario you choose, you still cannot come up with any continuum, either conceptual or empirical, between non-life and single cell life. You can't do this even if you're granted total liberty to imagine whatever conditions you want. All you can suggest are whimsical abstract proposals that are completely unsupported by science. You cannot propose anything that could be subjected to, as you say, the "rigors of science", because any such proposal would be immediately proven false.

The mindset of the evolutionist is, "If I can imagine it, it happened". In the case of abiogenesis, you can't even imagine it. Yet you still insist it happened.

Comment on the Wiki definition of Abiogenesis:

Abiogenesis (Greek a-bio-genesis, "non biological origins") is, in its most general sense, the generation of life from non-living matter. Today the term is primarily used to refer to hypotheses about the chemical origin of life, such as from a primordial sea or in the vicinity of hydrothermal vents, and most probably through a number of intermediate steps, such as non-living but self-replicating molecules (biopoiesis). Abiogenesis remains a hypothesis, meaning it is the working assumption for scientists researching how life began. If it were proven false, then another line of thought would be used to modify or replace abiogenesis as a hypothesis. If test results provide sufficient support for acceptance, then that is the point at which it would become a theory.


Abiogenesis does not qualify as a hypothesis any more than "A man can survive on Pluto" is a hypothesis.
THere is no proposed mechanism, no hypothetical pathway. All "intermediate forms" between non-life and life are abstract and not supported by any experimental evidence that such forms would be viable and could reproduce. The only reason for believing in abiogenesis is a prior commitment to the general theory of evolution coupled with a preconceived disbelief in intelligent design.
I could insist that a man can survive on Pluto, and defend my "hypothesis" with statements like "someday science will figure it out", or "research is actively underway". I could extrapolate studies on natives of Tibet that survive in frigid temperatures and high altitudes with low oxygen, and I could extrapolate that to Pluto. So far, the arguments I've heard in favor of abiogensis are no less absurd.
You point out self-replicating molecules produced in a lab and extrapolate that to DNA... and you call it "science". It is the antithesis of science. Science is about observation and experimentation, not putting on blinders and engaging in wild speculation based on ideology.
It's obvious that the only people who believe in abiogenesis are those who want to believe it. Real science is convincing to a skeptic.

One last comment on this thread: we DON'T extrapolate that to DNA! No wonder you're confused. What we do is view this as a fruitful avenue of investigation.

That a man could live on Pluto IS a hypothesis - it's just one backed up by very little evidence but that is (in theory) subject to experimentation and falsifiability.

You are using the property of self replication of proteins as evidence that abiogenesis, which includes the self organization of DNA, is possible. That is extrapolation. If you deny this, then please provide any evidence you have that DNA can form from randomly interacting molecules without referring to protein self-replication.

The problem is one of your own making, you will not be able to accept your own findings! Do you want to change your mind about accepting laboratory results?


Have you thought about what are you saying ? It´s difficult to believe that you are not seeing the silly argument you are using.

a. First of all I have nothing against the lab results itself.
b. The only problem is that they must simulate true natural conditions if the goal of the experiment is to show that a specific phenomenon can occur in nature.Abiogenesis experiments didn´t fulfill That task.
c. Second, an intelligent designer does not need to follow those requirements because an intelligent designer is not a naturalistic phenomenon.
d. Intelligent Designer is a person using his intelligence to build something.So, if a human being can build life in lab then he will have proved that life can be created by an intelligent designer.
(my paragraphing)

Re.a good.

Re.b debateable, because there is differing opinion on what the conditions would have been like.

Re.c interesting – if the intelligent designer does not use materialistic processes, how would you propose science test for a design then? If the intelligent designer just ‘snapped his fingers’ and DNA appeared, there would be no clues in the material world science could follow, to discover that design could it! Therefore, the search for an intelligent design can never be a scientific endeavour (this does not preclude the intelligent designer from being real however) can it?

Re.d And by your own logic be able to detect the design also (I mean if you know how to build it you know what to look fore), do you agree? So, can you say the same for the current situation regarding “is ID science” do you have an ID test?

IMO it is imposable for abiogenesis to form a single celled life form such as an amoeba in one go. Such life is far to complex to arise in a single event.

Springer>
Then we agree that single cell life is "irreducibly complex"? If you disagree, then please point out how a cell could be reduced to self-replicating autonomous units, or demonstrate how a cell could have evolved without resorting to vague undefined precursors that you cannot produce or demonstrate how they function.

If you agree that an amoeba could not be produced by a "single event', then you cannot rely on multiple smaller events unless you can show that each of these events produced some sort of autonomous self-replicating unit.


Yes single cell life is "irreducibly complex", I have never denied this. You seem to be under the impression that this fact disproves evolution, on the contrary it is support it, by showing how features are coopted and adapted, modified (sometimes poorly) from existing features.

Behe’s famous flagellum has been dissected aat the molecular level and an evolutionary pathway been built up showing the ancestory, see this link.

The links you seem to think not there are embedded in the DNA.

It’s not imaginary at all, there is supporting evidence.  I have posted my evidence many times now, so if you feel there is something ‘unscientific’ about it, then please enlighten me.

You have posted imaginary hypothetical precursors. Extrapolation of laboratory-produced self-replicating molecules to proto-cells does not constitute science.
It is nothing more than wishful thinking.


The self replicating molecules are real, why do you deny that such a thing is not valid evidence? I really don’t understand you reluctance on this aspect.

Re.a what is it that you find invalid about such conclusion?

Re.b there are lines of evidence to follow.

What I find most perplexing is your dismissal of the original premise of abiogenesis, based sole on the idea that it cant be replicated this very instance. So my next question is do you find the hypothetical position of abiogenesis inconsistent, if so what bit of it is? Perhaps if we get this question out of the way we can make some headway.
