Here are a couple of things on eye evolution I found interesting.

stop trying to enlighten people Frim. This should be a place of fun & ignorance. No learning allowed.
Thanks Frimmel that was interesting.

I understand the concept of evolution but I don’t understand where the ameba came from.
Evolution would say that over generations of organizims they change to adapt to their enviornment and to improve survivability rates. So where life come from in the first place?
Don’t get me wrong I don’t claim to be smart or educated so maybe I was just sick the day at school when they went from the big bang how the universe and planets were made and came back to day they started in on evolution.

:roll:
I always think learning is fun. :-)

Well I can’t claim to understand it all myself. I also don’t think any scientist can say for certain how it started and what exactly it started with. I just have frustration with the attitude that since the theory doesn’t answer ALL the questions that it is wrong or that it is somehow not an explanation for the known facts.
I strongly dislike when confronted with the idea that someone is dismissing the science because they don’t agree with the implications of that science.
I’m not saying it was / or is wrong I just ment I honestely don’t know how they made the leap from the universe to life.

This thread took an odd turn. I was mainly interested in if anyone had heard of a theory how a light-sensitive spot could evolve. The fossil record is very strong evidence that evolution occurs, but a good theory needs to answer all reasonable objections.
i am kind of an “intelligent design” type-guy. Don’t get me wrong - i am a scientist (M. Sc. Biochemistry and Molecular Biology, M.D.), but i also have some deeprooted and deeply contemplated religious (Christian) beliefs.
Having disposed of my credentials/biases . . .
In organic chemistry the use of “light” - i.e. different waveforms causes changes in the conformation of molecules to different energy-potential states (homo and luna states). This facilitates organic chemical reactions and is useful in a laboratory-type setting (note - i am going back 14 years in my education for this).
If we look at chlorophil - this is an excellent example of where light causes a conformational change in a molecule resulting in a move against entropy - i.e. the move from carbon dioxide/water/oxygen - to a more stable carbohydrate - cellulose etc.
If we look at the eye, there are molecules - rhodopsin and iodopsin being two more common - that when exposed to light (or a given wavelength - depending on the protein in question) will break down into smaller componant molecules. These will then go out into the wide world triggering a chain of events that leads to your perception of an image of various color and intensity.
So irrespective of the historical evidence of a figure named Jesus (why would Nero persecute the followers of a non-entity just 40 years after said non-entity was supposed to have died? - widely recorded),
i hope that this provides the missing piece/peace that you were enquiring about.

Eyeballs? intelligent design?
Try telling that to Harold Godwinson
More like mentally retarded design, even if you don’t understand evolution, why would God put eyeballs in such a vulnerable position
But what would I know, i wouldn’t have flooded the world either.
so where - outside of a skull that is pretty much built like a vault - would you have put them?
Not sure about the eyes, but I think moving the playground away from the sewers might have been a good idea :lol:

classic engineering joke!
functionally speaking, however, why not move all of your sewage out of the same pipes?
