I responded to this argument in post #531 (HERE), and your response? Silence.
This clearly demonstrates that your claim that all that atheists have presented in this thread is name calling and straw man arguments is false.
It shows that you are a liar. The argument I replied to is very much your position on the matter and is not a straw man.
From Lies, Damned Lies, Statistics, and Probability of Abiogenesis Calculations:
Quote:A primordial protoplasmic globule
So the calculation goes that the probability of forming a given 300 amino acid long protein (say an enzyme like carboxypeptidase) randomly is (1/20)300 or 1 chance in 2.04 x 10390, which is astoundingly, mind-beggaringly improbable. This is then cranked up by adding on the probabilities of generating 400 or so similar enzymes until a figure is reached that is so huge that merely contemplating it causes your brain to dribble out your ears. This gives the impression that the formation of even the smallest organism seems totally impossible. However, this is completely incorrect.
Firstly, the formation of biological polymers from monomers is a function of the laws of chemistry and biochemistry, and these are decidedly not random.
Secondly, the entire premise is incorrect to start off with, because in modern abiogenesis theories the first "living things" would be much simpler, not even a protobacteria, or a preprotobacteria (what Oparin called a protobiont [8] and Woese calls a progenote [4]), but one or more simple molecules probably not more than 30-40 subunits long. These simple molecules then slowly evolved into more cooperative self-replicating systems, then finally into simple organisms [2, 5, 10, 15, 28]. An illustration comparing a hypothetical protobiont and a modern bacteria is given below.
The first "living things" could have been a single self replicating molecule, similar to the "self-replicating" peptide from the Ghadiri group [7, 17], or the self replicating hexanucleotide [10], or possibly an RNA polymerase that acts on itself [12].
Another view is the first self-replicators were groups of catalysts, either protein enzymes or RNA ribozymes, that regenerated themselves as a catalytic cycle [3, 5, 15, 26, 28]. An example is the SunY three subunit self-replicator [24]. These catalytic cycles could be limited in a small pond or lagoon, or be a catalytic complex adsorbed to either clay or lipid material on clay. Given that there are many catalytic sequences in a group of random peptides or polynucleotides (see below) it's not unlikely that a small catalytic complex could be formed.
These two models are not mutually exclusive. The Ghadiri peptide can mutate and form catalytic cycles [9].
No matter whether the first self-replicators were single molecules, or complexes of small molecules, this model is nothing like Hoyle's "tornado in a junkyard making a 747". Just to hammer this home, here is a simple comparison of the theory criticised by creationists, and the actual theory of abiogenesis.
Note that the real theory has a number of small steps, and in fact I've left out some steps (especially between the hypercycle-protobiont stage) for simplicity. Each step is associated with a small increase in organisation and complexity, and the chemicals slowly climb towards organism-hood, rather than making one big leap [4, 10, 15, 28].
Where the creationist idea that modern organisms form spontaneously comes from is not certain. The first modern abiogenesis formulation, the Oparin/Haldane hypothesis from the 20's, starts with simple proteins/proteinoids developing slowly into cells. Even the ideas circulating in the 1850's were not "spontaneous" theories. The nearest I can come to is Lamarck's original ideas from 1803! [8]
Given that the creationists are criticising a theory over 150 years out of date, and held by no modern evolutionary biologist, why go further?
There is no evidence of going from one step to the next. That would be a leap. No, ID does not always just talk about going from simple chemicals to bacteria.
