Hello,
first of all: I'm a creationist, but I'm also interested in evolution. This is not intended as criticism on evolution, I just made this thread out of pure curiosity. I hope I've put it in the right forum though.
As far as I know, evolution is based on the variation of DNA. Since the DNA describes the life-form, a variation on DNA will also variate the life-form. So the life-form will improve through this very variation on the DNA via mutation, selection and, if there is sex, crossing.
There are some well known arguments against evolution, like predecessors of some complex system a life-form possesses, like e.g. the eye, which would not show any advantage to the life-form and so could not have developed. We all know that specific argument and the solution to it, which makes this argument 'proven' wrong.
One thing is buggin' me though: The development of the DNA itself. I would like to describe my problem on an unicellular organism to keep everything simple. The DNA describes the cell, the cell is able to copy itself, so: the DNA also describes 'How To Copy'. The DNA has to be read, to be copied. This ability to copy seems to be a very complex system, and, it makes evolution, like the one I learned of in school, all possible. Without it, you would have only cells unable to improve themselves via mutation and selection. So the Question of mine is: how could such a complex system like the DNA come to existence?
It may be, that I miss something here ... unfortunately I'm not good enough to find a satisfying answer with Google... so I'm trying it here.
Please excuse my very bad English... hopefully you'll understand it anyway.
regards,
qpwoeiru.

if you ask a creationist, the answer you will get is "inteligent design"
if you ask an evolutionist, the answer you get is "by chance"
I personally believe in creation. but am not so nieve to over look the fact we live in an infinite universe. there fore infinate possibilities for things to happen 'by chance'.
but good luck ever trying to replicate those conditions. its like floating in space, and throwing a bucket of sand at earth. hoping that by the time it reaches land the sand has turned into a computer chip. in an infinite universe is is possible, but far from likely

When your basic premise is wrong, you can be almost xertain that your conclusion will be. A light-sensitive cell - just one cell - on the skin of one animal (remember, we're talking aquatic life here, so 3 dimensions) would warn it when a predator was approaching from above. (Light would be blocked, even if only a little.)
And, as Darwin pointed out, evolution proceeds by survival of the more fit (I don't know who misquoted that at "the fittest"). Being just a tiny bit more fit means that you'll out-reproduce those just slightly less fit - to the point that after a few thousand generations (and the eye probably evolved from a light-sensitive cell to something you'd call an eye over hundreds of millions of generations) your variation would be the only one in the species.
Irreproducible complexity is a joke, at best. We've seen that we can have something serve one purpose, then evolve into another one. (The limbs of lungfish, for example, can't support the weight of the body, but they function quite well in an aquatic environment. Then when they strengthen - for whatever reason that happened - they work on land too.)

why would a fish that ,by some chance ,gotten a one cell of light, be more fit,when it never needed it before? Who gave it the intellgence to use it,and how to interpet that a darkness of light is a predator,that may be attacking it? How did it know that it needed that light cell in the first place ? Where did it find that light cell ? If the light cell was a good fit , how did it know to pass it along to the others, being that it may of not had the reproduction cell to pass. Does not dna only pass along info that it already has, because it can't pass new info, that it does not have from it's rna code? where did the first cell get it's energy,to produce ATP (adenosine triphosphate), if it gets it from raw material , if animals and plants did not make it constantly,they could not live, how long could living cells of live b4 there learned how to make ATP ? just questions, didn't know the answers to?

I assume you are talking about the evolution of the eye. This started long before the fish. One celled animals today have eyespots. Since an organism that can detect

Doesn't need intelligence, if an organism moves the right direction it's more likely to live.

How does oxygen 'know' to combine with hydrogen to make water?

Copying errors can be passed along, this is new information.

Why do you think the first cell needed ATP?
just questions, didn't know the answers to?

The first step to getting the right answer is to ask the right question.
If you have any information from Kent Hovind, throw it away.

Pogge:” This is the volume of a sphere with a 62 kilometer (about 39 miles) radius, which is considerably smaller than the 2,000 mile radius of the Earth.”
Wikipedia:” For Earth, the mean radius is 6,371.009 km(≈3,958.761 mi; ≈3,440.069 nmi).”
Wisp to Lester (on Pogge): Do you admit he was wrong about the basics?
Lester: No
