First of all, I made it a point to state that I do not oppose macroevolution/abiogenesis because I'm a Christian, I oppose it because it's bad science, (in fact I think it is actually a religion mascarading as science) and yet, you can't seem to help yourself in trying to make it a creation vs evolution issue by attacking the Bible.

Well it's probably a good ideal to FANTASTICALLY simplify something FANTASTICALLY difficult to demonstrate a basic concept. Why can you not understand that this post is not a complete simulation of how an eye first formed? It's not supposed to be absolutely accurate, it's not supposed to take all things into consideration. I could do it 1 to 1 million and greatly offset the chance of the eye improving at birth, and you'd still EVENTUALLY end up at 1 million. I could add in other survival factors like negative and positive mutations elsewhere on the body. But this is a quick explanation for those who don't understand the concept at all, so I'm not going to.
First of all it's "idea" not "ideal." I understand this is a simulation, however, the oversimplification of your simulation gives an incorrect impression, therefore it is a bad simulation. The process is not that simple and you tried to gloss that over and you are still trying to do so. You also failed to state that this is a simulation of how some scientists (not all) think a process MAY work, your whole post makes it seem you're explaining how a process works and there is no proof that it does work that way. You are also underestimating the ratio of negative mutations to positive mutations aren't you?

That's because it's extremely difficult to find large amounts of transitional fossils because fossils are very rare things. However, there are some transitional fossils.
These are fossils of different life forms, there is NO proof that one led to the next... the fossil record somehow loses the millions of life forms that would have to exist from one to the next, how interesting.

There is no macro or micro evolution in the form that theists use it. There's no magic line between mutations and change of species. Fundamentally we are the same as apes. We are just different enough that we put ourselves in another group. If you accept that it's possible for species to mutate and keep those mutations over time, and deny that it's possible for one species to change into a new one, you're simply being ignorant.
Millions of generations of fruit flies have been born and died in the labs, with all kinds of allele changes taking place and yet we have not had ONE birth that was not still a fruit fly, and we've had MILLIONS of mutations occur and they were ALL bad for the organism.
QUOTE
We don't have any real largely differing qualities from an ape. There's no "eye" in this situation. You could make a rudimentary ape from a human being if you had a slider with different traits like: "Hair, skull shape, size", etc. The way their body works is the same, with a few differences here and there.
Wow, you really do believe things are that simple don't you? If we're so close to an ape why is it that humans can't successfully breed with apes? After all, lions can breed with tigers.
QUOTE
I know. I said it's not "one random chance and pow you have a complex organism", as many theists sadly think it is.
Still trying to make it a creation vs. evolution issue. IT'S NOT THAT AT ALL, GET IT THOUGH YOUR HEAD, WE'RE TALKING ABOUT THE SCIENCE OF THIS THEORY BEING BAD.
QUOTE
IAMS, I don't know how many times I will have to explain that this is not a scientific essay on evolution. This is demonstration of a concept, and only that.
I never said it was an essay, I did not criticize it as an essay on evolution,I criticized it as a weak example.
QUOTE
I can't explain to you exactly how the formation of an eye would start. I'm not a scientist. I would guess that the organism ends up with a phew photon receptors, then over time more and more and can sense the direction light is coming from, then something to focus the light so it can see sharper images, etc.
Have you any idea how complex just a system of photon receptors is?
QUOTE
As for would they be able to use the new mutation once they had it? Well, that's a good question. Although I know that when people have a large-scale mutation like an eleventh finger they can use it.
Yes, they can use it, but is there an advantage in it? Does it get passed on to offspring? If it gets passed on, is it any more useful to the offspring?
QUOTE
*Sigh*, this is not an example of the development of an eye. This is a demonstration of the CONCEPT of how an eye might develop. Anyone can call something a bad example when they're looking for something more than they were told to expect. But that's alright, I knew nobody would be able to take this thread for what it is.. and I'd receive the utmost scrutiny from the suddenly skeptical theists. Isn't it funny how an old illogical book, very little if any proof, and really good PR has the theists sold on creationism yet they are unwilling to accept a simple demonstration of the concept of evolution because it does not fully and completely explain the process and address every potential pitfall?
I'm not teaching science here. I'm giving a basic primer on the theory of evolution for people who accuse it and know nothing about it. I also find this post from you funny, because how many different and polarizing teachings and interpretations are there of the Bible, the cornerstone of all Christian faith? These day's it's hard to find two Christians who completely agree on what the Bible is trying to say and means! (I'm not pointing this out to shift the topic, I simply don't like hypocrisy, and I see very much hypocrisy in your criticism).
Yes, I was assuming there was already some structure there for an eye, and how it may evolve to be a complex eye from that point. But again, this is to show a concept, it's not to prove how the eye evolved. I don't want to over-complicate something with a simple objective.
Still trying to make it a creation vs. evolution issue? IT'S BAD SCIENCE!!!!

No, I understood that you're not religious. The bold part was referring to Iams. And how would they be given the wrong impression (If anything it would be much more accurate than "apes magically became humans after a little while of changing")? That's the fundamental concept of evolution, nothing more, and I didn't try to make it anything more. It seems like people want to nitpick at my post as if it's an article in a popular science magazine or something, when it is, was, and was presented to be a very simple representation of the basic principle of natural selection.
And all I said was that it's a weak example. When did I bring in religion?

And I was originally going to do the experiment on a 1 to 100 basis, only I forgot that that would have taken up a couple pages of numbers and x's. If I'm demonstrating concept there's no reason to do that. I can show you how to jump rope by doing 5 repetitions of rope-jumping or 1,000. Either way, you'll know that I'm swinging the rope under my feet and back around again. I never inferred how much closer towards a perfect eye they were getting in each cycle, and if you scale it up it would be very little gain per generation, I think anyone who could follow the post should understand that.
Sure and the simpler you make the example the more viable it appears, that is why it's a bad example, it's so simple it's become fiction.

1. I showed you transitional fossils. Those would be evident of a change of the animals leaving those fossils. Since we do not see creatures with the same skeletal composition anymore, we can imply that whatever it was no longer exists and has changed into something else based on the slow progression of the appearance of the fossils.
You showed fossils theorized to be transitional, there is NO proof they are transitional, they could just as well be animals which had been around all along, and which had been previously left out of the fossil record since, as you have pointed out, fossils are very rare. What proof do we have that just because these fossils only appear in one part of the fossil record that was the only period of time these animals existed? How can we be sure they hadn't just not left fossils previously? See, there's a whole bunch of assumptions there.
QUOTE
2. Pig organs (or sheep organs, etc) are used, that's true. Why? Well, just because one species is closer to a human does not mean every aspect of that species is closer to a human. I would also guess there's the factor of size, and supply (I don't know if pig organs are actually more similar to human organs than ape organs or not). We kill pigs for food, we don't with apes, and there are more pigs on this earth than apes.
Doesn't this apply to apes too?
QUOTE
3. And I'm dreaming if I think evolution can create a new class/family/species? How so? If mutations can form and be passed on what exactly would you propose eventually stops large-scale mutations from happening? Small things eventually add up, that's a fact. If in a thousand years things like height, bone mass, etc could slightly change, what's to say that in a million years you couldn't have thousands of changes like that? And in a billion years millions of changes? It's a fact that once something changes enough it becomes unrecognizable with respect to its original form.
If I lose some weight and breathe in enough helium, and if the gravitational field of the Earth suddenly weakened at just the right time, I could float 100 feet into the air.

4. And no, I don't care to open a thread about the difficult points of darwinism, because I'm not a scientist and I wouldn't know what I'm talking about. I wouldn't go to a television repair place and start telling them which transistors on my TV need replacing (or what have you) because I wouldn't know! I do know that well-trained scientists spend a lot of time researching and testing theories. That's what gave me this laptop I'm typing on, that's how people knew to cause the chemical reactions that power it. If I have to know in-depth everything a scientist is saying to actually believe he's not lying, I'm going to be studying different sciences every last second of my life. Where's your mention of all the potential complexities of gravity? Or do you not doubt gravity? I bet you couldn't tell me the complete inner-workings of gravity and vacuums in space, but you know that the textbooks aren't lying when they say you're being sucked onto this rock of an earth.
Do you have even the vaguest understanding of gravity? "sucked onto this rock.." Do you know that we have absolutely NO real idea how gravity works? We know how to calculate it's effects, and how to predict many things with these calculations, but we don't KNOW how it works.
