Both the theory of evolution, and the theory of abiogenesis concern themselves (in part, though not wholly) with the probability of information gain, though in different capacities.
Evolution presupposes a simple code sequence, capable of self replication and possible mutation. From this basic starting point, there are theories describing different replication "errors," an error being anything other than a perfect copy. Errors may take many forms:
1) There may be a single substitution, where one bit of code information is exchanged for another.
2) There may be deletions of one or more bits of information.
3) There may be duplications of any portion of the code, from a single bit to the entire sequence, spliced into, or attached to the end of, the previous sequence.
4) There may be inclusions of code from an outside source, from a single bit to an entire sequence, spliced into, or attached to the end of, the previous sequence. This presupposes compatible sequences of differing codes.
A) The results of one part of the code may effect the expression of other parts.
Examples of mechanisms by which errors occur on modern codes are known. Highly probable examples may be found as evidence of these mechanisms functioning in the past. (if I were to find a chapter of shakespeare in the middle of an orwell novel, even with a few misspellings here and there, I could assign a probability to the fact that this is an inclusion, and possibly even where it came from, and I could also assign a probability having found the doubling of a chapter within a book) Note that it is possible for information to be gained, lost, or changed by these errors happening in sequence. Note that both examples of high statistical probability, and observed examples are both accepted as evidence. Note also that, as the required sequence of events increases, the less likely it is to be directly observed, but that this does not detract from that sequence's probability. (as an example, if I suggest an exact random sequence for a shuffled deck of cards, the larger the number of cards that I specify, the less likely that I may observe it within a set amount of experimental observation, but this in no way limits the possibility of that sequence arising given more time than a human observer can or will spare)
Abiogenesis is a less robust theory, but it has advanced in leaps and bounds in recent years. Abiogenesis is the theory that a simple replicator has a statistical chance of randomly occurring given a set of materials and circumstances theorized to be available on the early Earth, within an amount of time bounded by the habitability of the environment of the newly formed Earth, and the earliest fossil evidence of simple life. (which is a surprisingly short span) Further, the theory of abiogenesis requires that this replicator must be capable of mutation, at which point the result is handed to the theory of evolution. This is truly the statistical leap that opponents often level at evolution, though such criticism should instead be leveled at the theory of abiogenesis.
One misunderstanding of abiogenesis is to suppose that a simple replicator must posses the complexity of a modern cell. This is simply not so. Laboratory research has demonstrated that replicators may be very simple bits of coded chemical chains such as RNA. Still improbable, but far less than the astronomical improbability of a full cell spontaneously generating.
In conclusion, the theory of abiogenesis addresses the formation of a replicating sequence, an encoded chain of chemicals capable of replication error, and the theory of evolution addresses the results of competition among differing code sequences.
An explanation of molecules to man requires both of these theories in sequence.

Re: Probability and information gain
Mon, July 6, 2009 - 8:58 AMI think one of the problems that most people have with probability theory is that in the public mind it is equivalent to the "law of averages". The idea that every thing will average out in the end.
Las Vegas was built on this misconception.
First there is no "Law of Averages".
Probability very simply says that if something is possible that it will happen if given sufficient opportunity. Think about the infinite monkey theorem - en.wikipedia.org/wiki/Infi...ey_theorem
>An explanation of molecules to man requires both of these theories in sequence. <
This is also a misconception - or perhaps misstatement on the part of creationists.
To use the automobile as an example one can draw a straight line from the Conestoga Wagon to the Ford Mustang but this would be a very narrow view of available facts.
Just as there were many different lines of transportation - most of them unknown to us today - that branched off early horse drawn wagons there many branches from many points in the history of evolution.
It is the totality of the evidence that must be weighed.
Each new piece of evidence must be given equal scrutiny with all the evidence that came before it.
We must also be ready to keep or discard old and new evidence and even whole theories as new and better evidence presents itself.
This is the great fault of creationism - they have decided what the truth is and must then fit the facts to it. -

I don't feel you said anything here. You seem to have been trying to work up to a *point* that evolution can be modified or discarded, while creation cannot, thereby proving that evolution is, walla, a scientic theory! Unfortunately, your argument doesn't follow. Evolution cannot be discarded because no other naturalistic explanation of origins is or will ever be available. We have come to the point where it doesn't matter whether it is true or not, only that it is an explanation which doesn't require "God". Both evolution and creation can be modified up to a point. Creationists have mostly tossed the vapor canopy theory for example because this model would superheat the earth. Creationists must accept that God did it, that he did it in 6 24hour time periods and that Noah's flood is world wide. Much discussion and disagreement revolve around many other issues such as plate tecktonics etc.
Evolution can accept many different ideas. Some hold to "punctuated equilibria" which was advance by the late Dr. Gould. In his work he denied transitional fossils exist! (later he tried to recant while still acknowleging it??). Others are gradualists. But you cannot toss evolution for a anything else, this is not allowed! So in this manner, evolution is 100% EXACTLY THE SAME AS CREATION. A model of origins which ultimately must be believed by its adherents, but never proven! Sorry Joe, I know this hurts.

Interestingly, you start with "evolution presupposes". Yet no independent "simple code" exists as far as we know anywhere in the universe! Why do you suppose that evolutionists wish to stack the deck in their favor right from the start? I can think of some reasons, can you?
You go on to list some types of mutations which can occur, some which may (or may not) add information and some which actually lose information. Then you state that known examples of these mutations exist, but fail to cite any information gaining mutation series in the germ cells of any organism which has been observed anywhere in any laboratory in the world. Major omission don't you think?
"Highly probable examples may be found as evidence of these mechanisms functioning in the past."
What does it mean to say that "higly probable examples may be found"? Isn't the issue whether or not they have been found? Of course, if a complete transformation of one cell into the entire biosphere did occur, it is highly probable that we would find millions of examples, but this is begging the question. The issue is, we have not found any..... (Of course, one must qualify this as evolution believers are adept at advancing so-called evidences for their theory, give them an international spotlight, then ignore them once real science demonstrates they are not really valid at all!)
Finding a copy of shakespeare in another book may demonstrate that it has gotten their from another source (binding error at the factory perhaps), but NO NEW INFORMATION HAS BEEN ADDED TO THE WORLD, BECAUSE SHAKESPEARE ALREADY EXISTS! Are you starting to get the point??? Duplications do not add information. And the contention that they provide the raw material for future information is not evidence, it is conjecture!
An evolutionist pressupposes that similarities in organisms is due to homology, but this is not necessarily so. Similarities can also be due to common design. I can find many similarities in the numerous bridges I have driven over, but they did not evolve from one another. In like manner, the creationist would expect similarities between organisms which God has created, this is no surprise. So this "evidence" is not useful in this debate, because it can be fit into either model of origins.
Evolutionists who don't understand information science often claim that "time" is the savior. "Given enough time, helium turns into people" or so we are told! But saying so doesn't make this true. Sir Fred Hoyle for example, after looking at the incredible challenge of life evolving on the primordial earth, give up atheism and declared with his colleage, "There must be a God!"
There is no evidence that life started as a "particle". All known "particles" exist as obligate parisites. None live independently, none! So it is reasonable for creationists to insist that evolution believers must prove that it is possible for a living cell to "spontaneously generate". Of course, there is not science which proves that such a thing is possible and the more we learn about living things the more complex we find that they are. There is no such thing as a "simple cell". But probability is not the only issue here. As Grim mentions we have habitability issues as well. It appears that not all places in the universe are equally hospitable to life. We live here on earth in a "goldilocks zone", an ideal place for life. Yet even if the universe were filled with "earths", there is no reason to believe that life could have evolved even once!
Let's keep things simple. Let's look at an example of the probability problem evolution believers face.
"The theory of evolution
Further tests exist to measure how efficient chance is at producing design. The following is fascinating. The question is: What is the expected probability for chance to spell the phrase—‘the theory of evolution’? This phrase by chance would involve the random selection and sequencing of letters and spaces in the correct order. Each letter from the alphabet plus one space (totaling 27 possible selections) has one chance in 27 of being selected. There are 20 letters plus 3 spaces in the phrase—‘the theory of evolution’. Therefore ‘chance’ will, on the average, spell the given phrase correctly only once in (27)23 outcomes!!
This computes to only one success in a mind boggling 8.3 hundred quadrillion, quadrillion attempts (8.3x1032) (gasp!). Suppose ‘chance’ uses a machine which removes, records and replaces all the letters randomly at the fantastic speed of one billion per microsecond (one quadrillion per second)! On average the phrase would happen once in 25 billion years by this random method. If, as evolutionists would have us believe, the earth has been in existence for approximately 5 billion years, then ‘chance’ could take five times this time to spell out its own success, even at this phenomenal rate of experimentation. And this phrase is infinitely simpler than the smallest life form, and children of average intelligence could perform this same spelling task within a minute or so."
Now if you were to apply probability equations to the probability of life spontaneously generating on the primitive earth, you would quickly see that the unlikelihood is insurmountable. It would not happen in 4.5 billion years or 20 billion years. It would not happen at all. Hoyle was right, here must be a God!
"An explanation of molecules to man requires both of these theories in sequence. "
correct, no abiogenesis, no evolution. So evolution is not possible, on any level. It could not have started, no evidence suggests that life progressed in this manner so I rest my case, the only other option is Biblical Creation. -

I am sure that if you put your mind to it, Dan, you could think of thousands of other options, or is your mind really so limited?
Invoking an unknown force (your God) as an explanation does not seem warranted as there is no evidence, or even any slight indications that such a force exists. Surely you could imagine thousands of different kinds of unknown forces that might accomplish the feat, why home in on one that can be shown to be false by the very book you use as a point of reference for the unknown force?
>>"Further tests exist to measure how efficient chance is at producing design."<<
These mathematical models creationists cite are not well informed and don't even partially represent the processes known to be active to produce evolution. Good mathematical models have been formulated and used in a number of computer programs, that show that the processes underlying evolutionary theory are indeed viable and produce the expected results, so really all this noise about evolutionary theory lacking a good mathematical basis is moot. You need to work up some different arguments. -

Re: Probability and information gain
Sat, July 18, 2009 - 6:12 AM"I am sure that if you put your mind to it, Dan, you could think of thousands of other options, or is your mind really so limited? "
Sure, I can imagine all sorts of things. But I am not a fan of science fiction Rene. That is the problem. The creation evolution debate is not about our "imaginations", it is about reality. It is realty that I am pointing to when I say that evolution has no chance at all.
"Invoking an unknown force (your God) as an explanation does not seem warranted as there is no evidence, or even any slight indications that such a force exists."
I am always amazed at how you word things to make them appear to be of substance when there is none at all. The case for a Creator is overwhelming and god deniers are without a smidgen of excuse Rene. Nor is this force unknown, as He has revealled himself in the Bible. If you applied your skepticism of God to evolution, I would say that you would abandon this ridiculous theory "with prejudice".
"Surely you could imagine thousands of different kinds of unknown forces that might accomplish the feat, why home in on one that can be shown to be false by the very book you use as a point of reference for the unknown force?"
are we back to our imaginations again? My mind is reality based Rene, I have never had a good imagination. Nor can I think of any "force" other than an infinite, all powerful, personal one that could be responsible for all that we observe around us. The one described in scripture fits perfectly, and nothing in scripture has been refuted by you or anyone else. Information, or a code, has never been found anywhere to have created itself. It is always the product of intelligence. Life is always observed to come from pre-existing life, no exceptions. You often state that there are mountains of overwhelming evidence for evolution, but upon close examination of the evidence you present, we find that it evaporates. Yet there IS mountains and mountains of corroborative evidence for the biblical God, you just dismiss it on the grounds that He cannot be observed with your eyes. Apply this absurd standard to evolution and you will join me in dismissing it as a scientific theory!
>>"Further tests exist to measure how efficient chance is at producing design."<<
"These mathematical models creationists cite are not well informed and don't even partially represent the processes known to be active to produce evolution."
true, if they were more rigorous the unlikelihood becomes even greater. Sir Fred Hoyle understood this, which is why he abandoned faith in atheism. Antony Flew saw this, and the worlds foremost atheist author also abandoned atheism. Creationists aren't the only ones who have found that the probabilities are too small to be considered possible, many evolutionists have arrived at the same conclusion. Dean Kenyon, former evolutionist who wrote the book "biological predistination" (advancing your notion of determinism), abandoned the theory altogether and is now a leading proponent of Intelligent Design. Dr. Werner Gert is an accomplished scientist with numerous scientific papers published is an information scientist. Perhaps you would like to read one of his articles on the subject:

"Good mathematical models have been formulated and used in a number of computer programs, that show that the processes underlying evolutionary theory are indeed viable and produce the expected results, so really all this noise about evolutionary theory lacking a good mathematical basis is moot.

The arguments are sound, and everyone knows this Rene. If you don't, it is because you are uninformed. Cooked computer programs do not help your theory at all.

What exactly is real here, Dan. All you have is a book of old myths, similar to many ancient myths and legends; what it describes has no more reality for us than "Middle Earth", which in many ways is a more believable story than those in your bible. An "infinite, all powerful, personal" force... what exactly could that be; what have you observed with your "reality based" mind at all indicative of such a force?
>>"...mountains of corroborative evidence for the biblical God"<<
Most Christians readily admit no such evidence exists; this is why they put great emphasis on "faith". This is why is is referred to as the "Christian Faith". Also, as I have already clearly demonstrated on the "Resolved" tribe; the bible itself proves that the "biblical god", as defined by the bible, cannot exist:
