To the evolutionists... I need answers.?

Question

The human eye consists of around 20 sub-organs (eg. lens, retina, etc). If one of them is not in place, we would not be able to see properly. If one is not fully evolved, we cannot see properly either. So how come for millions of years until we developed eyes, we could survive without seeing?! Shouldn't we have been extinct due to "survival of the fittest"?

Also the cilia in the lungs consists of 10 proteins that allow it's motion. If one protein is not filling the "ring" making the cilia, our lungs would be full of dust and disease due to our cilia's infunctioning, then die out! So how did we pass these barriers to evolve?

Wow, no answer...

ok, finally an answer... yet it doesn't explain how we could have possibly evolved. And why are Atheists tryna AVOID creationism... what if it's right? I'm a Muslim (not a terrorist you idiot) and I believe i can be wrong with my beliefs about evolution, but it's just not logical.

Somebody please show me that evolution is logical, or stop teaching it at schools as if it's real.

OK, nice responses guys...

Evolution seems logical now, but the "chance" factor is just too high. So i believe that there MUST have been sumthing controlling these processes along the way. And the thing is that Islam is NOT against evolution... in fact, read this:

"Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe? (The Noble Quran, chapter 21 : verse 30)"

Answer 1

This is the quintessential example of the argument from incredulity. The source making the claim usually quotes Darwin saying that the evolution of the eye seems "absurd in the highest degree". However, Darwin follows that statement with a three-and-a-half-page proposal of intermediate stages through which eyes might have evolved via gradual steps (Darwin 1872).

photosensitive cell
aggregates of pigment cells without a nerve
an optic nerve surrounded by pigment cells and covered by translucent skin
pigment cells forming a small depression
pigment cells forming a deeper depression
the skin over the depression taking a lens shape
muscles allowing the lens to adjust

All of these steps are known to be viable because all exist in animals living today. The increments between these steps are slight and may be broken down into even smaller increments. Natural selection should, under many circumstances, favor the increments. Since eyes do not fossilize well, we do not know that the development of the eye followed exactly that path, but we certainly cannot claim that no path exists.

Evidence for one step in the evolution of the vertebrate eye comes from comparative anatomy and genetics. The vertebrate βγ-crystallin genes, which code for several proteins crucial for the lens, are very similar to the Ciona βγ-crystallin gene. Ciona is an urochordate, a distant relative of vertebrates. Ciona's single βγ-crystallin gene is expressed in its otolith, a pigmented sister cell of the light-sensing ocellus. The origin of the lens appears to be based on co-optation of previously existing elements in a lensless system.

Nilsson and Pelger (1994) calculated that if each step were a 1 percent change, the evolution of the eye would take 1,829 steps, which could happen in 364,000 generations.

Answer 2

"chance factor"

What do you mean by chance factor?

Chance has nothing to do with it. Life exists, therefor the odds of it occurring are irrelevant. Duh.

The environment forces change, and adaptability, and can reward sophistication. How can evolution not occur? If an ice age began tomorrow would life around the globe adapt and evolve? Of course. The answer is so obvious that to argue against evolution seems ridiculous.

Answer 3

Simple, these organs and sub-organs gradually evolved and became more complex as life itself evolved and became more complex. Eyes evolved to see based on the visible spectrum of light from the sun that reaches Earth. Some deep sea species have never evolved eyes, they didn't need them. Environment dictates necessity and necessity dictates evolution. These "barriers" you refer to ARE the reasons life evolved that way, they dictated necessity, so your question is rhetorical.

Answer 4

Why did one of the gods make such a complex system for humans on the flip side? Why such a frail system that if one thing goes wrong, so much can happen in your body? Seems rather haphazard for a "god"? For that matter, why would a god make a system that needs money sent to him?

Answer 5

Heh, heh ... well I guess when your grasp of reality is so loose, that creationism is just the nice neat little answer you need.
