Another take on the irreducibly complex eye: Sea urchins are one big eye
| September 12, 2011 | Posted by News under Irreducible Complexity, News |
Their whole body surface is are their eyes, as we hear in “Sea Urchins See With Their Whole Body” (ScienceDaily, September 12, 2011):
he research group behind the study showed that the photoreceptors seem to be located on the tip and base of the tube feet that are found all over the sea urchin’s body and are used to move.
“We argue that the entire adult sea urchin can act as a huge compound eye, and that the shadow that is cast by the animal’s opaque skeleton over the light-sensitive cells can give it directional vision,” says Dupont.

It seems this “take on the irreducibly complex eye” shows photoreceptors are useful to multicellular animals without a formal eye, and therefore eyes are not irreducibly complex.
DrREC, seems you certainly lost no time in skipping right over the wonder that this well research finding, of ‘one big eye’, presents to us. Does even the hint of design ever even enter your mind when you are presented with such a startling surprise as this? ,,,,But to counter your claim that such a wonder found of ‘one big eye’ in the sea urchin is supposedly ‘easy’ for neo-Darwinian processes to accomplish, and that the human eye is therefore ‘no big deal’ for neo-Darwinian processes since, by golly, the sea urchin can see, do you suppose you can calm these irrational doubts in this almighty power of neo-Darwinism that I have, powers that that you seem to be so sure of, and please demonstrate the evolution of even a single opsin gene/protein in any animal that does not have one already? Just one opsin gene/protein???
etc.. etc.. etc..
I have speculated that if there is a creator and a single blueprint for everything then it follow eyesight is just a single equation.
It should impress that most of biology has just eyes like us and then insects etc have JUST another type of eye.
This seems unlikely if a creator was creating diferent eyes for different needs or evolution since surely endless oprtions of randonness would make almost as mant results in important ways.
Why is eye design so sticky?
It seems like there is just one concept to eyesight.
So perhaps all seeing ability is simply a single equation and these urchins hint at it.
why should they be so different from everyone else?
They are not I suggest.
They hint at a better idea in understanding how sight works.
so creationism is shown more likely and possibly a new equation of seeing can lead to healing/fixing sight issues.
This would be a gain for me.
