Welcome to the fray.
Nice point on the probability. I ran it for all five with a probability of 1 in 1000, where the "all at once" argument calculates the probability at 0.0015 or 1 in 1,000,000,000,000,000 (your typical astronomically impossible number) And the one by one events work out to:2nd one in 4 = 0.00399 (1 in 250.4) 3rd one in 3 = 0.00300 (1 in 333.7) 4th one in 2 = 0.00200 (1 in 500.3) 5th one in 1 = 0.00100 (1 in 1000) SUM = 1 in 2284.7 to finish the job Not only that, but as you add more "complexity" to the issue you are adding in smaller and smaller increments.a sixth bond would add a 1 in six = 0.00598 or 1 in 167.1, and a total of 1 in 2451.6, a 7th would add a 1 in 7 = 0.00698 or 1 in 143.3 and a total of 1 in 2595.1 diminishing increments the further you go (an expotential decay I believe) and certainly well within the realms of possibility by anyones stretched imagination. then add to this the probability that any of a number of complex amino acids can result as stable molecules (your "retrodiction" comment applied to the molecule in question) and you start getting multiples of possible ends instead of 1, and those multiples reduce the {1 in 2284.7} or {1 in 2451.6} or {1 in 2595.1} by the same amount if I needed to make any of {1 of 100} 5-bonded molecules I now have a 1 in 22.847 probability. and even that does not complete the possibilities, as any duplex bond could combine with a triplex bond set instead of adding single bonds, and the longer the molecule you need the more possibilities there are for joining smaller multi-bond molecules. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

try this again and see if I can get through it without crashing ... (don't you hate losing posts just before you post them?)
Jacinto writes: You extrapolated my calculations out even beyond what I thought necessary ... the more bonds take place, the more potential bonding sites to the molecule are created yes. you piqued my interest in seeing what the final result was for strict comparison to develop a preselected formation. if you do open it up to the probabilities of creating a soup with varieties of amino acid building blocks then each addition can be thought to have the same probability of bonding to any previous location, thus the fifth and last of a 5 bond molecule would have a 1 in 1000 probability with each of the previous 4, or a total 1 in 250 chance.
As if the amino acids discovered in the Murchison meteorite weren't sufficient and the lake tagish meteorhttp://web99.arc.nasa.gov/PDF/tagish.pdf and the organics found in deep interstellar space (and hence as old as the light path ... ), unfortunately my link to Identifying polycyclic aromatic hydrocarbons in space is broken now (such is life in cyberspace), but I have these quotes from it (saved at another site):
August 13, 2001 Polycyclic aromatic hydrocarbon (PAH) molecules are the most abundant family of molecules in the interstellar medium after molecular hydrogen and carbon monoxide, and contain about 10% of all the interstellar carbon. Recently, a spectral database has become available from the Infrared Space Observatory that contains objects in which we have found the C-H PAH stretch feature (near 3.26 m) in absorption. Using the database of isolated neutral PAHs generated by the Ames Astrochemistry Laboratory, we can match the interstellar feature fairly well with a mixture of PAH molecules. However, the mixture is not unique and does not tell us which particular PAHs are present in space. This is demonstrated in the Figure which shows two fits to the absorption observed towards the protostellar source S140. The laboratory database contains only a few PAHs as large as those expected to survive the rigors of the interstellar medium, so it is perhaps not surprising that a precise match is still not possible. Techniques for obtaining lab spectra of larger PAHs exist, but making large PAHs for lab studies is very difficult. Once such lab data exist, being able to directly compare lab and interstellar spectra without using uncertain models could provide the first identification of individual PAHs in space. this is also mentioned in:http://pokey.arc.nasa.gov/%7Emax/abstracts.html there is also Scientists Toast the Discovery of Vinyl Alcohol in Interstellar Spacehttp://www.spacedaily.com/news/life-01zi.html also see NASA - Origins of Lifehttp://www.resa.net/nasa/origins_life.htm and Nature - Mineral brew grows 'cells' (need sign-up\sign-in)Mineral brew grows 'cells' | Nature Maselko and Strizhak mixed calcium chloride, sodium carbonate, copper chloride, sodium iodide, hydrogen peroxide and starch. They found a fungus-like, soft membrane grows out of the mixture, enclosing a hollow cavity up to 1 cm across. Chemicals diffuse through this membrane, react inside the cavity, and then diffuse out, creating swirling clouds of violet liquid in the green base solution. Rather than reaching equilibrium, this process persists. The reactions, say the researchers, are reminiscent of the way living cells sustain themselves, driven from equilibrium by the flow of chemicals and energy across their membranes. if you access the webpage there are some cool pictures. enjoy. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I am going to assume that as any part of the bicycle plans ("DNA") are available to chose from and mix parts into new arrangements, I also have access to the "DNA" of other mechanisms as possible things to evolve on a bicycle.
Thus adding a battery powered light to the bicycle to use in the dark is an evolutionary advantage over the plain bicycle. Adding a generator to the system is a further improvement that is selected for as it extends the operation of the light. (I used to have a bike with a generator built into the front hub for a most efficient system). Increasing the size of the battery now enables me to use the generator as a motor to assist in peddling in the tough hills, but generate electricity to store in the battery when the goings are easier, an improvement that allows more or bigger hills to be covered. Increasing the size of the {generator\motor} and the capacity of the storage battery to give stronger and longer power assist on the hills is also selected as having an advantage over the smaller systems until a compromise in size and weight is reached, at which point stasis sets in for a while. Then I add a small motor to the generator to assist the generation of electricity, allowing the battery to be smaller and still get the same overall result, plus now I need to pedal less to generate the requisite electricity to use in the hilly areas. Finally I link the motor directly to the drive mechanism to get around energy lost in the various intermediate stages, and allow the {generator\battery} system to atrophy and fall off. The motor continues to grow and take on more and more of the actual task of propulsion. No biggy eh?

heh. thanks (both of you). Note, it's complete with an IC twist at the end, just for kicks.
actually I have been toying with a hydraulic powertrain for a recumbent bicycle (a friend is into restoring classic bikes and has a workshop) and that would probably be better able to turn braking force (kinetic) back into stored energy (potential) with a pressure tank. that would be fun.

LOL
and that is the difference between evolved mechanisms and designed mechanisms the other thing I forgot to mention is that due to the original generator evolved design, the motor is mounted on and connected to the front wheel, a design that limits the size the motor can grow due to the imbalance problem: thus you see small motor assisted bikes in europe (where the motor sits on top of the wheel and drives it very much like the generator image here), but all the big motorcycles have rear mounted motors that drive the rear wheel -- much more efficient from a design and function standpoint. problem is that there is no way to "evolve" from a front mount to a back mount system, a situation that shows up in evolved features all over the place. enjoy. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

well that was part of my caveat at the beginning: that other "DNA" could be incorporated. basically saying that if it can evolve once it can evolve again given similar materials and selection pressure for its existence. we know that several forms of eyes evolved because of the basic incompatable differences (nautilus eye retina faces light, human retina doesn't ... and there is no way to "flip" the retina), therefor to posit a species evolving an eye is not a stretch and making a step that incorporates that understanding is basically shorthand. of course I could have broken it down into little steps, but I would still be writing ... the selection pressure was based on better survival (seeing in the dark, plus protective coloration to discourage attack by larger vehicles) or by accomplishing the same tasks with less peak output of energy. but aside from that this has served as an exellent platform to discuss just these differences (breaks arm patting self on back) we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

Jacinto's calculation was purely in answer to the creatortiontista calculation of the improbability of a (already occuring) molecule being formed purely by chance.
The point is that their calculation is so grossly in error because of errors of omission, most notably here, the ommision that the order of the formation is irrelevant to the final product. The point is to compare the 1 in 1,000,000,000,000,000 (your typical astronomically impossible number) with 1 in 2284.7 calculated using Jacinto's method, a 437,700,000,000th reduction factor. your points are valid with these caveats: add {energy\catalysts\non-aerobic environment} to the system and those reactions can be enabled One recent paper at NASA looked at the molecules on the murchison meteor then added the energy of impact of a typical meteor and looked at the result: some molecules combined. see {SURVIVABILITY OF SIMPLE BIOMOLECULES DURING EXTRA-TERRESTRIAL DELIVERY: THERMAL EFFECTS} abstract athttp://pokey.arc.nasa.gov/%7Emax/abstracts.html about 3/4ths down the page we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

there's also
"Macro" vs "Micro" genetic "kind" mechanism? (click) looks like SonClad is still finding his way around and may need a little help. welcome to the fray SonClad! look into all the different forums as there is quite a diversity. There is also a search function, so if you want to talk about a topic you can search for a thread that has already been opened on it. enjoy. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

you keep putting selection back into the picture while auser_maat keeps trying to ignore it to make his (thereby corrupted) point. problem is that auser_maat is not discussing evolution but a strawman. by our ability to understand RebelAAmerican.Zen[Deist

things get borrowed from other designs, too, sort of like convergent evolution. sometimes things are outright stolen -- hybridization and inter-species breeding (like mules/hinnies and tigons/ligers). More like horizontal transfer of a whole feature so that you cannot reconcile a common ancestory pattern - because there are two or more different ancestors to the design in process. This is the biggest failing of ID - good design would predict this occurring, fossil & genetic evidence says it doesn't. by our ability to understand RebelAAmerican.Zen[Deist

I used to live in Mississippi, down on the coast, and one night I went into the dark kitchen hearing a noise, turned on the light and a 3" roach leap off the counter landed on my stomach and ran down my leg to get away.
The next day I got roach traps. Lots of roach traps. And spread some borax around the edges.Cockroach Organic Control Information Of course if one were looking for a good survival design ... I don't think humans would make the cut: too much politics and bickering to really get anything done on a useful time-scale that would anticipate problems (global warming as a case in point). {nods towards topic} Enjoy.
