I know someone else famously declared that god must have an inordinate fondness for beetles but, with the creationists going on about rapid devolution via micro-evolution post-fall and post-flood (ie the only kind of mutations and changes they will accept being negative because they are out of their tiny little minds with the rapture), it would be more "logical" to them that god really hates beetles and cursed them more or did little to prevent their "decline" into speciation.

That was all one sentence.

Our eyes serve us quite well enough, I'd guess, and that's really all evolution does; make do with a minium of fuss. If, someday down the road we'd need better vision to get our supper, it would evolve it from what we have.

The fat, little opossum that shares my digs has excellent hearing and a sense of smell that can only be described as superb. But his vision is barely good enough to keep him from bumping into trees as he makes his nightly rounds. That's all he needs, and his species is highly successful; indeed, one of the few, small mammals in the US that is actually expanding it's population and range.

Might the 'possum's eyesight improve? Unlikely, I'd think, unless the species took on a whole, different lifestyle. Might ours evolve? Probably not because, like the opossum, we compensate; they with nose and ears and ourselves with optic devices.

Giving the posting history of Danpech (two posts yesterday after a long, long time and all the former posts in the more philosphical forums), I hope he actually comes back to answer some of the posts here.

I heard, in a lecture on optics, that this was because the photosensitive cells have to be near a blood vessel because they are extremely fragile and need to be repaired almost constantly.

You seem to be missing the point that the cells could be the right way up while still being next to the blood vessels (and nerves). It is like saying that someone has to walk on their hands in order to be in contact with the ground rather than flying, when they would actually do better on their feet.

And secondly and more dramatically, the retinal cells are not anchored into their blood supplying tissue by the ‘wiring’, which means that the retina can detach rather easily. I also used to say that a blow to the head would cause this (which it can), but it seems in fact that it more often just detaches spontaneously. This is a Bad Thing™, because the retinal cells then die, making their owner blind.
A coworker of mine is going through this as we speak. He's been through multiple laser surgeries over the past few months to try and repair the holes that are forming in his retina of the right eye. All that's been accomplished so far is blurred vision, and a larger blind spot.

His optomotrist told him that these holes aren't really caused by anything in particular. The only reason he found out early was because he was scheduled to have LASIK done to improve his supposedly "perfected design" of vision, and was then told they couldn't perform the surgery due to this complication.

I was personally thinking, "God is a cockroach, as those suckers can survive anything: nuclear holocaust, plague, unintelligent people...."

I have this problem with my right eye, my doctor assured me I don't have too worry about going blind ( anytime soon ). At first there was a subtle but anoying effect which would make straight lines in the affected part of my field of vision to look bent. Another effect was thas I had problem reconizing people because the features of the face were subtly distorted. Now I just have a vague spot in my field ov vision, but my brain helps me ignore it.
Ok enough whining. Can I sue God for malpractice?

Get thee behind me in the queue. This whole body is not fit for the purpose of living on this planet and I've been waiting for a replacement one (body or planet) for ages.
