Beneficial mutations
I have proposed a thread for you to attempt to back that rather silly and unfounded statement up.
When it is promoted you can give your reasons behind:
..too bad mutations are never beneficial to any species whatsoever.
It's title is "beneficial mutations".
please this is not the thread to rebut this statment. Thanks.

Different kinds of calculations
By taking "calculations" to cover all different froms could we not consider:
1) Evolutionary algorithms which show that the process can produce design-like outcomes (designoid).
2) Models which show how mutations can spread or not and be fixed or not
3) The calculations that correlate mutations rates and the dates obtained by fossils for the separation of lineiages.
I'm not sure what other kind of calculations that someone could be talking about. Has that been clarified yet?

Zero Selective Pressure?
If organisms never change, the selective pressure must be zero. You are talking about a calculational model of evolution.
I think the contrary. With genetic drift and constant mutations occuring I think there must be a selective pressure there to mantain and organisms form. The pressue is, however, to stay where it is. This would be true if it at an adaptive peak in a reasonably constant environment.

A model
Creationists would like to see an evolutionary model concerning the probability of evoltuion since then there would be something critiqueable.
It is not very clear what you mean by an "evolutionary model". Perhaps you described what it would look like it might be possible to point something out to you.
I think there are a number of possibilities for this but if you described a bit of what you are looking for it might help.
I might also suggest that before you get into the ToE (the model of how evolution happened you might want to move back to basics first.
Remember it was bible literalists who started down the path that has gotten us to where we are. It might be an easy intellectual journey if you traced their steps. If you jump into information theory and mathematical models (which some of your post hint that you are not ready to deal with) you will only get confused.
How about this order:
1) How old is the earth?
2) How do we determine that?
3) Has life on it remained fixed in form for that time?
4) What was the nature of the changes in the forms of life and at what times?
5) Finally, how might these changes have come about?
It was Bible accepting Christians who worked through all of these things starting about 300 years ago.
Darwin only answered the last question 150 years ago. While question 4 will be ongoing indefinitely.
If you are a YECer and think that the earth is only 6,000 years old then there is not good discussing evolution in any form with you. If I thought the earth was only 6,000 years old I would be rather mystified as to how evolutionary theory could be a reasonable answer.
If you insist on jumping in without the foundations you will be forced to reject what you don't understand or accept things because someone says so without understanding it either. I don't think either approach is a good idea.
(some side notes: I have had enough courses on statistics to recognize the flaws in the Dembski arguments. If you haven't you will have to start there by getting an education in probability calculations. If you keep the excellent tone that you started with then there are many here who can help you along. Everything you are asking about (other than the topic of this thread ) has been discussed a lot in the Intelligenet Design and Origin of Life fora. )

Information Theory
To help you with some of the discussions on "information":
CSI and Design
A fatal logical flaw in creationism?
Complex Specified Information (CSI)

The avatar is a picture of one of the characters in the series. Her name is Seven of Nine, maybe you can do a bit of googling yourself.
You spelled oogling wrong.

Information?
Suppose a DNA sequence which specified some trait were laid out as follows. IWILLCREATEAHAIRFOLLICLE. Then it mutates or replicates and mutates. ILLEICRSKDLFIELCKSHEIATEID Have you created any infromation?
Yes, if I use the only rigorous definition of information I know of. Do you have a definition of informtition where there isn't additional information? There have been numerous times where creationists or IDers (if there is a difference) have been asked for a definition of information that is useful to determine the answer to your above question. However, none is forthcoming.
BTW Message 55 was a request for the nature of the answer that you seek. You haven't gotten to it yet.
However, naturalism and evolution have made it "far more comfortable to be an intellectually fufilled athiest" according to Richard Dawkins
Yes, this is when the argument from design was nullified since a process that can produce design-like results has been shown.
Evolution will fall not because of creationism's triumph, but simply because the mechanism is seriously flawed and cannot produce the complexity and vast amounts of information on our planet.
Since it has been shown that the mechanism can produce "informtion" and "complexity" (with some uncertainty about what you mean by those terms) what is it that limits the mechanism to producing ever larger amounts? You have made a blanket assertion here. I suspect it is one that you have been feed and have no clue how one might support it since you never thought to ask for support for it. This is know as an argument from incredulity and is a very weak argument indeed.
Actual evolution tends to go toward greater complexity, species becoming more elaborate in their structure and behavior, though the process can also go in reverse, toward simplicity. But DNA on its own can go nowhere but toward greater simplicity.
Your discussion here was copied from elsewhere. It is appropriate to give your source when you do that.
This experiment does not show what your source suggests it does. In the experiment outlined the more successful DNA (and I thought it was RNA so I think that might be wrong) was the faster copying. Therefore it was selected. That will, as in nature, move it to "simpler".
In the same way parasites will evolve to be "simpler".
Separately from this DNA can (gene duplication for example) increase in "complexity".
NOTE: all the " " 'd terms must be rigoruously defined before the discussion can continue. The ID'ers make use of these terms but do no t know what they mean to themselves or anyone else.
{qsEvolution is directional. Look at where you start and look at what we have. Less Complex to more complex. While you may want to apply this to a smaller subset of events, or get philosophical, evolution is nothing without the ability to produce increasingly complexity. Otherrwise, you and I don't exist my friend, and that would get very philosophical.[/qs]
while you are suggesting books I would suggest Gould's "Full House" for a discussion of the apparent direction in evolution.
As noted the process can produce more of whatever it is you are talking about.
Do you seriously believe that life sprang from non life? Is it probable in your mind? Was it clay templates and billions of years, hot vents on the bottom of the sea floor, panspermia. I don't expect an answer, just an honest assessment
Off topic in a thread about evolution I would say. Why not take it to one of the "Origin Of Life" threads.
Our point is that information does not spring from non information any more than energy can be produced from a perpetual motion machine. Creatures change as the information they pass from generation to the next is recombined, selected, deleted and then conveyed in a new offspring. DNA is a lot more complex than throwing dice. You don't just reconstitute new DNA structures by random processes and create meaningful information.
Please define "information" as you are using it here. By any definition that I have seen the above is wrong.
