Darwin himself said his theory of evolution was absurd ...That the human eye alone is so complex it could never evolve naturally ... Somehow Darwinist continue to find a way to ignore this fact ... If Darwin were alive today would consider believers in evolution morons...
Could we have a source? Because Darwin says otherwise in
The Origin of Species.
Eyes are a particularly fascinating point of evolution. They're hardly proof for the existence of an intelligent designer any more than your own left arm is. Now what Darwin did to rebut this argument about eyes is particularly interesting. He surveyed existing species with functional and useful eyes and tried to see if he could string them into a hypothetical sequence that would produce the complex eyes we have today. And he did it.
You can start with simple eyespots that detect light in flatworms. From there, you can see how it would fold in, making a cup that protects this eyespot, and better localize the light source. Limpets have these sort of eyes. In chambered nautilus, you see the cup's opening narrowing which produces an improved image. In ragworms, the cup is covered by a transparent cover, in abalones, fluid in the eye forms a lens to help focus light. In mammals, nearby muscles help with focus and with moving the lens. And so on and so forth until you reach the current eye we ourselves have.
If that wasn't proof, there's a pair of Swedish scientists by the names of Dan-Eric Nilsson and Susanne Pelger who made a mathematical model concerning the evolution of eyes, similar to the path I just described. Starting with the basic eyespot, they allow the tissues to deform themselves randomly, limiting the change to about 1% of size or thickness at every step. To imitate natural selection, the model only accepted the mutations that would benefit the organism, as any that didn't would allow that organism to die off.
Well, the model worked, much like the progression that Darwin described. It went through 1,829 tiny adaptive steps. And how long did it take? Nilsson and Pelger calculated it, and it would take, using conservative numbers, less than 400,000 years. That's more than enough time for an eye to evolve in organisms, especially considering the earliest eyes started to arise more than 550 million years ago.
So, how is this proof of an intelligent designer again?
