First off, I am an atheist.I will not for a second pretend that I am scientifically education in evolution...I think it's a pretty easy theory to grasp; humans, as we know them, evolved from some type of primitive life.Personally, I am not big into trying to answer life's questions. While I generally tend to side with evolution (only when it's considered the black to creation's white), I really don't care that much.My question is this:I once heard that in all the evidence of evolution, there is no indication as to how the eye evolved. Supposedly there was no organ that performed functions similar to the eye before the eye itself shows up in animals.Is this true? If not, what was this organ that developed into the eye?Since the majority of people who believe strongly in evolution or creationism hang out in the "Religion and Spirituality" section, it is very appropriate for me to post this answer here, as I will likely find someone who knows the answer.If you don't think it should be posted in this section, too bad. Don't "answer." Otherwise, you are going to be reported for cheating for points.Thank you to everyone who explained this and provided websites and such. I guess I am also wondering if any type of primitive life with a partially developed eye that evolved into the human has been discovered?Or would the eye have developed to how we know it long before this primitive life differentiated into something like a primate?InteriorCastle--you are the exact reason why I will never believe in God. Your ignorance obviously extends much further than your fairy tale beliefs.

Not to be rude, but this question has absolutely nothing to do with religion and spirituality. You should ask this in the biology section or something.
 
The eye is not irreducibly complex. Go to talkorigins and search. It will explain everything.
 
I wasn't there, but I would think it started as photosensitive cell. Or at least Dawkins does in "The God Delusion"Read it.Looking at eagles hawks or giant squid you could argue that we do not have "fully evolved" eyes.
 
Not true. They stated off as light sensors and became more developed over a long period of time.
 
im not an expert in evolution, but i know some about it. im almost positive it came from the nervous system and the brain. Feeling was the only sense some plants have, if any at all. The other senses came with the animal needing to know more around its surroundings to survive.
 
The eye's evolution is actually well-known. We can see the different stages in various organisms.Here's a video that explains it on an elementary level.
 
I am not a super Wikipedia fan, but this is a good article that pulls it together in a short format:http://en.wikipedia.org/wiki/Evolution_of_the_eye
 
This is an untruth that creationists spread.Here you go: http://www.talkorigins.org/indexcc/CA/CA113_1.htmlGoogling "eye evolution" will give you the real story, plus links to hundreds of christian sites repeating the false claim.
 
First, I accept evolution. The eye thing is weak. They sunburned nerve end doesn't do it for me. BUT here is what is conjectured. The simple light-sensitive spot on the skin of some ancestral creature gave it some tiny survival advantage, perhaps allowing it to evade a predator. Random changes then created a depression in the light-sensitive patch, a deepening pit that made "vision" a little sharper. At the same time, the pit's opening gradually narrowed, so light entered through a small aperture, like a pinhole camera.
 
Incorrect. Even in modern animals we see simple patches of light-sensitive cells, 'pinhole camera' eyes, and a myriad of other forms that can be put into a rough line of simple to complex lightsensing/visual apparatus. So it's incredibly easy to see how the eye evolved.
 
Actually, this is a complete falsehood perpetrated by fundamentalists.There's a pretty straightforward progression when it comes to eyes. In fact, the eye could be the most easy to explain of all the body's organs. In most animals, skin cells have a certain sensitivity to light. All that would have to happen is for some of those cells to increase their sensitivity....and it just goes from there.Plenty of books explain it.
 
Seeing as evolution takes faith i suppose you're in the right place.Micro evolution is true, but we call it adaptation, if you get sick, you will build an immunity to the sickness, however with the immunity, after long you will no longer need it because your body hasn't had to fight it, so it fades away.Macro evolution has not been proven, it has no hard evidence, no recorded instances that SHOW that something has altered permanently due to an outside stimulus. People feel natural selection is an answer to this however, it has been shown countless times, that mutations are usually horrifically destructive and never result in anything beneficial to the organism that carries it.Certainly there may be physical similarities between different creatures, however, one thing that is missing is the creature that falls between the two (or realistically it would be many) a good example is that someone could say A horse and a dog are similar in build so it could be suggested that a dog came from a horse or vice versa, however I don't see any dog/horse hybrids anywhere, not even in the fossil records. So logically you can't deduce that they came from one another.Another explanation is that they may have come from a common ancestor. The problem I find with this is that it has been proven that altering the physical attributes of the parents of a species does nothing to alter their children. so even if the external world changes, though they may have to adapt, they will not change permanently.Evolution takes as much faith as a religion.
 
There are literally thousands of transitional forms of optic organs represented in the living life forms on the planet today.Part of the confusion is that most of these get labeled as "eyes" even when structurally and functionally they are very different.Some organisms have "eyes" that are no more than a collection of cells (or even a single cell) that can detect changes in light intensity - i.e. tell the difference between whether it's dark or light. Others have a cluster of cells - so that shifts between which cells detect dark and which detect light can allow the organism to detect movement.Although these are called "eyes", they are definitely a far cry from the more complex organs with sheets of multi-colour sensitive cells on a retina, a lens and iris system to focus and adjust for light levels, and muscles to adjust the field of view - but each of the stages functions very well at the task it is supposed to do.
 
Use your head, why would there be anything like an eye -- which is no good except for seeing -- why would it keep evolving to that blind point just before one can see. You are pig-headed. You believe what you darn well want to. And excusing it as 'I don't really care that much' OR 'I am not big into trying to answer life's questions' -- That just marks you as a trivial person.
 
We don't have any fossil eyes to look at, but clues to the various stages of the eye's evolution can still be seen today in modern animals. You have simple unicellular creatures with a light sensitive spot, then you have worms with a cluster of light-sensitive cells at one end, then you have the horseshoe crab that has the light-sensitive cells in a pit so it has a little directionality, then you have the murex snail which has a pit with a simple lens.So there is good reason to believe that the eye has continued to evolve through all the stages of our evolution from worm-like creature or even earlier.
 
i know your gonna get a answer for this question and it doesn't matter what it is. if it's right or if it's wrong......... it's a miracle......... evolution happening is a miracle taking place no one can reproduce it. no one can make evolution happen. there is only one that can
