Origin of Vision Discovered
LiveScience ^ | 10/18/07 | Andrea Thompson

Posted on 10/22/2007 9:07:09 PM PDT by LibWhacker

You are reading these words right now because 600 million years ago, an aquatic animal called a Hydra developed light-receptive genes—the origin of animal vision.

It wasn't exactly 20-20 vision back then though.

Hydras, a genus of freshwater animals that are kin to corals and jellyfish, measure only a few millimeters in diameter and have been around for hundreds of millions of years.

Scientists at the University of California, Santa Barbara studied the genes associated with vision (called opsins) in these tiny creatures and found opsin proteins all over their bodies.

These findings, detailed in a recent issue of the online journal PLoS ONE, counter arguments by anti-evolutionists that evolution can only eliminate traits and cannot produce new features, the authors say.

“Our paper shows that such claims are simply wrong,”

I couldn’t get past the first statement—as if anyone was around 600 million years ago to see this......

As if you need an eye witness to prove everything that's ever happened.

Of course they weren’t there 600 million years ago to see this, because if they were, they wouldn’t have had eyes to see it with, since the creature with the light-sensitive gene was just coming into being.

I’ve always thought a security camera would be a good featuer for my house, but I didn’t want to spend the money. Now I am holding out hope that my outdoor lamp’s photo-cell will evolve into at least a black-and-white security camera. Then I just have to run some wires.

Any suggestions on how I can speed up the process? I suppose I could just use the original process, and design and build a camera myself, but this evolution thing sounds so much easier.

Yep, God said, let there be light, Jesus said, give them eyes to see, and the Holy Spirit said, may that “sight” lead them back to God.

No, you just need an eyewitness to know HOW it happened.

On CSI, no matter how much they get the physical evidence, they always seem to end by getting the perp to CONFESS to the crime, thus providing the eyewitness testimony.

BTW, anybody catch the CSI where at the end, the woman who killed the scientist is given a pass because she THOUGHT the guy, and obvious environmentalist whacko, had killed her son?

When they figured out who really did it, and didn’t think they’d get him, I wondered why they didn’t just tell the woman who the real killer was, and let her go off and kill the guy, since apparently the CSI folks don’t think it’s their job to put killers in jail if they did it for the “right” reason.

Yes, have your security camera reproduce sexually, and apply selective pressures to the offspring.

That isn't possible? Then maybe you need to find yourself a more suitable strawman.

No problem. Give it a few million years, be sure to weed out ones with worse image detection (i.e. those with uniform sensitivity), and select ones with better imaging detection.

OK, that went random on me, sorry.

If you find a pencil on the floor, you can assert that there is a pencil on the floor. If you find 11 other pencils on the table above the pencil on the floor, and an empty package that says “12 #2 pencils”, you could assert factually that there are 11 pencils on the table. If they have the same serial number, you could assert as fact they came from the package.

But you can’t assert as fact that the one pencil rolled off the table and onto the floor. Sure, it looks like it, but what if I placed the pencil on the floor? It would look JUST like some natural process caused the pencil to be on the floor, but in fact it was a creative act.

Which is why CSI is a television drama, not real life.

In real life, people are convicted every day of the week for crimes for which there was no eye witness and no confession. The idea that we can't know anything if there wasn't a witness is really kind of strange, certainly 100 years after the discovery of modern fingerprinting. Fingerprinting works to solve crime scenes; likewise genetic "fingerprinting" can help us unravel the past.

Yet the case you mentioned, the dead boy, was solved without the help of any eyewitness.

Not really. But given the level of understanding on this board(with a few notable exceptions) you couldn't be expected to understand.

Except hydra are animals and paramecia are protists, suggesting you don't know what the heck you're talking about.

Take even an intro bio course and you might be a little more able to avoid making yourself look like an under-informed dingbat.

But...but... they couldn’t have been around 6000 million years ago. The earth was a red hot ball of fire back then, waiting for that inter-stellar rain cloud to come rain on it for a few million years and create life, or rather, premadoral soup from which life magically formed...

Of course all these evolutionary “steps” require incredible odds, well beyond 600,trillions of billions to one. Not just once either, but many millions of times. But they happened, because evolutionists say so.

No, but you do need someone who was around at the time to document that it actually occured.

Have you tried putting it in a spot where it gets lots of rain? alternatively, you can hook up a garden hose and have it drip constantly on it. Seems to do the trick for life on earth.

Yes, have your security camera reproduce sexually, and apply selective pressures to the offspring.

In the endless world of unguided happenstance that allowed matter to spring forth form the complete absence of matter - extreme complexity to spring forth from the complete absence of complexity - and life to spring forth from the complete absence of life....this is possible. To deny this is to deny the base foundation on which scientific evolution of something-from-nothing is based. Take this security camera and an endless amount of years....you know, monkey's with typewriters creating Shakespeare.

BTW: nothing applies "selective pressures" to the offspring - that would be a force guiding evolution which is absolutely contrary to Darwinian Orthodoxy. If something is "applied" - it implies an applier....so to speak.

Not true. If lightning strikes a tree we can tell lightning struck the tree even if nobody was around to document it. And if we dig up the fossilized stump millions of years later, we can still tell lightning struck it.

Amazing isn't it? Yet those slimey paramecium's never developed any. They just remained slimy paramecium for 600 million more years, never changing into anything. I still say the eyeball was the first living thing on earth, and just developed the opropriate body and apendages suitible for it's location and needs. a pair of eyeballs crawled out of the ocean and turned into mankind. The key to it all is rain. Lots and lots of rain.

:rolleyes: This has been done to death. Complexity doesn't arise at once. If you had actually read a biology textbook you'd have a much better perspective. As it stands you're just another brainwashed creationist drone.

You don't understand selective pressures either.

Not true. If lightning strikes a tree we can tell lightning struck the tree even if nobody was around to document it.

Or perhaps it was a forest fire of some kind? In any case it is a huge difference to tell how lightning struck a tree versus how eyes somehow eveolved.

Now now now lets not bring religion into this. I am only referring to scientific orthodoxy. Religion is based greatly in the idea that God inspired the Bible. There were eywitness accounts of things wich occured in the Bible but the Bible (for example and for the most part) deals with the supernatural.

Nice try but don't change the subject.
