If evolution were true, there would've been significant advantages to having infrared vision, since infrared is "always on," constantly emitting heat information about the temperature of objects.
Hooray, it's the Argument from Undesign:
* Evolution should have made us absolutely perfect ... because ... uh ... well, it just should, that's all.
* We aren't absolutely perfect.
* Therefore we were designed by a perfect, infallible, and all-powerful God (who, evidently, reallly screwed up).
For my money, this is amongst the funniest creationist arguments. Especially as the premise comes from a bunch of people who spend much of the rest of their time pretending that evolution is a completely random process.

Re: What about the other guys?
* off-topic nonsense snipped *
If you wish to be wrong about the age of the Earth, you should really start another thread.
Evolution did not bring us here. We are wonderfully and fearfully created beings, by a loving God.
Though apparently he didn't love us enough to give us infra-red vision.
Next time you're praying, could you register a complaint, and explain to him how evolution would have done so much better than he did?
The only reason many of us won't see that is because we are wrapped up in ourselves. It's pride and arrogance which separates us from God.
And there was I thinking it was pride and arrogance that separated creationists from science.
Oh, and ignorance, of course.

Re: What about the other guys?
Subbie, my position is this: *IF* ToE was true, it would've produced evolution.
And it has.
It hasn't provided you with infra-red vision, but then apparently we can survive and reproduce perfectly well without it.
Have you noticed that humans are diurnal?
Since I believe it is not true, and since I believe we were created by God, then God gave us what we *NEEDED* to get by here on Earth.
But evolution will also only give us what we "need to get by", it won't supply us with gadgets and toys that would merely be fun to have. Have you heard of "natural selection"? Does the phrase "cost/benefit" mean anything to you?
I don't think we should have IR vision. I am only saying that if ToE is true, we should have.
But you have failed to make your case.
Tell me this --- if you think IR vision would be so darn useful --- have you bought yourself a pair of night-vision goggles?
I haven't.

Re: What about the other guys?
(1) - Were evolution true, we should have IR because of its enormous advantages affording 50% more opportunity for breeding, feeding, foraging, etc.
When would we sleep?
We already have enough time to breed, sleep, and forage. Doing more of the same would be a bit of a waste of energy. Doing it in the absence of visible light would be a foolish waste of energy.
(2) - Because we don't have it, it doesn't mean we're missing something and God was a bad god because he didn't do it right. It only means that He did everything necessary to give us everything we need so that when we die and see Him, we will be without excuse.
I still don't see why you think that the ramshackle, makeshift, make-do, trial-and-error processes of evolution should have produced a better result than a perfect creator.

How would this be a benefit to warm blooded humans? The radiant heat from our heads would spoof the receptors. Imagine trying to see when your eyes are glowing like light bulbs.
I was just going to post this, and then I noticed you had.
---
Rick --- Larni is right. We're endotherms. Our eyes are kept constantly at body temperature. If we had IR vision, we still wouldn't be able to see warm-blooded animals at night, because we'd be blinded by the IR from our own eyeballs.
This is why, in endotherms, all adaptations to nocturnalism involve making better use of visible light (and other cues, such as smell).

Re: What about the other guys?
Your question pre-supposes there is a need for sleep. I see no reason why an evolved creature would have a need for sleep.
You don't?
Basically, for the same reason that my monitor powers down if I go long enough without using my computer.
Sleep is a huge liability because the bulk of beneficial attributes (thought processes derived from observation and stimuli) are completely disabled.
As are the bulk of costly activities. At a time when we couldn't use 'em well anyway. 'Cos of the absence of visible light, and the impossibility of IR vision in endotherms.

Re: What about the other guys?
This is a very false statement within the system of evolution. Evolution will supply what is needed to survive, but that does not mean it will only provide us with things that are needed.
Yes it does (broadly speaking, and ignoring minor changes due to genetic drift). Every structure comes with a cost. An unnecessary structure is disfavored by natural selection.
It will, necessarily, provide us with things that are no longer needed and are, therefore, now useless.
But it won't supply us with things that were useless when they were supplied.
It may supply features which lose their function (and which will then be degraded into vestigial features) but it will not supply us with features which start off being useless.
For example, suppose there was a particular type of airborne creature that was killing another creature. That creature might evolve some ability which allows it to not become extinct. Over time, that creature might perfect that mechanism of defense so that the flying creature is no longer a threat to it.
Some other creature may then develop some advantage which allows it to kill all of the flying creatures. Or maybe there was a volcanic eruption which released chemicals poisonous to it. Now, the first lifeform which developed all of these whizz-bang defenses against the now dead creatures is carrying around useless abilities.
And the genes for those features would deteriorate through genetic drift, since they would no longer be conserved by natural selection. Resulting in the sort of vestigial features so commonly observed in nature.
Evolution gave us what we needed to "get by" when the threat was there, but because evolution is a full-on system with many facets, another part of evolution removed the threat we previously had.
There should also be evidence of this were evolution true.
There is.
It's funny, most creationists take the route of denying that vestigial features are evidence for evolution. You admit that they are, but deny that they exist.
Have a look here and here for starters. Or see if you can find out why humans have a broken gene for producing vitamin C.

Re: What about the other guys?
Science today is creating artificial structures that do not require sleep. Nanoscopic electro-chemical-mechanical systems. They can operate continuously without sleep.
Yes. You, on the other hand, can't and don't need to. You can survive and reproduce just fine while also "powering down" eight hours out of twenty-four..
It has been shown that even today there are people who can get by with 1hr of sleep per day. It would've been an evolutionary advantage to not sleep, and therefore it is something that should've evolved.
No. It has an exorbitant metabolic cost with no concommitant benefit.
IR is not impossible in endotherms. It's only impossible if you use materials which are not invisible to infrared light.
Read through those two sentences again.
Costly activities are only "costly" because there are not adequate systems which keep everything in operation. Evolution should've sorted that out.
Your expectations that evolution should be omnipotent seem now to extend to demanding that evolution should have produced creatures that can defy the Laws of Thermodynamics.
Doing anything has an energetic cost. Except maybe falling off things.
Evolution should've sorted that out. If cells were not getting enough oxygen, then a better circulatory or respiratory system. If cells were not getting enough energy, then a better endocrine system or digestive system.
Well of course evolution has improved all these things. But not to the extent that we can violate the laws of physics.
If cells need to take a break, then have cells which switch off and work 50% of the time on some kind of duty cycle.
Thus we would operate all the time but at only half the power. I'm not sure that this would be an improvement. I wouldn't be able to stand up, but at least I could lie awake all night ... no, I really don't think I'd be better off.

Re: What about the other guys?
There may not be a cost to the ability gained by fending off the flying creature. Maybe it was skin pigmentation, or an ability to lay flat. Those traits may not otherwise impede anything.
Skin pigmentation requires proteins to make the pigments out of which could otherwise be used for other purposes.
If an animal originall can't lie flat, presumably this means that its morphology is better adapted to doing something else. There are, to use an analogy, no tank/sports car combinations.
By definition it will. It will supply us with a wide array of things which are useless. However, in a few generations those creatures with the useless (potentially costly or harmful) traits would've died off. That doesn't mean they won't come. And in a true evolutionary system, they should be coming constantly.
You're talking about mutation, I'm talking about evolution.
As you say, there is a cost. If the cost is zero, then useless features will abound. They will be introduced into the creature and, if they don't hurt anything, will continue to exist. And, they don't have to be external. Internal genetic modifications which have no outward effect. In DNA there are portions which we believe today are useless. Evolution would introduce random static and trash into those unused portions if they had no cost in the outcome.
That's genetic drift, which I exempted.
I don't understand where people get the idea of features disappearing through genetic drift. This does not happen. There are no creatures today which are not already programmed with a wide array of abilities which, over time, will be weeded out of the genetic code (or active genetic code) by selective breeding or the "micro evolutionary process" which does actually exist (changes made from information already there).
I'm stating that evolution does not exist in the form that we came from pre-animate goo to where we are today. Micro-evolution does exist, and does allow dogs, over time, to be bred into taller dogs, fatter dogs, longer dogs, etc. But that does not mean a dog can produce a non-dog.
Features will not simply disappear if they are not needed. The natural variations within that organ's features, or within that gene's features, will allow whatever changes are possible for that thing over time to come out. But that does not mean it will go away. If the ability is already there encoded within it for it to go away, then it will go away. If it is not possible to take it away then it will not go away, it will simply move about into whatever ultimate form it happens on over time - per the evolutionist's theory.
That is not "the evolutionist's theory", that's something you've pulled out of your ass.
There are no vestigial features. If something is there, it has a purpose. Rather than me following those links, sum up in a paragraph or less what you believe are vestigial features.
Unfortunately, a paragraph is insufficient. That's why I supplied you with links.
And I don't see how what I wrote could be less than a paragraph unless I wrote nothing at all.

Re: What about the other guys?
Yes, and were an agressor species to come along I would be wiped out - which is what should've happened many millions of years ago according to evolutionary theories.
No. There are agressor species, and yet you live.
Okay, meaning if you assume the lens and materials between the lens and the receptor are visible to infrared, then it won't work. But if you use materials that are invisible to infrared light, then no matter what temperature they are infrared will pass right through it.
I still don't think you've got the point.
You emit infra-red. A receptor which detected infra-red would detect you, as being the nearest source of infra-red.
Your inability to grasp the concept I'm explaining here relating to IR invisibilty components does not allow you to claim things about my level of understanding on anything.
The boot would seem to be on the other foot.
I do not buy the cost factor of metabolism, and therefore the necessity of sleep, because in an evolutionary system all of those "costs" are just variables that could be overcome.
Good grief.
And you say you studied physics.
No, evolution cannot perform actual miracles. Activity has an energetic cost.

Re: What about the other guys?
Or it means its morphology hadn't yet evolved the ability to lie flat which, from that point forward it could now do and is of benefit.
It would help if you could discuss some concrete example rather than something you're making up as you go along.
Mutation is the only component of evolution that allows something over time to change.
Yes. And any mutation which is useless and costly, or which costs more than it's worth, will be flushed from the gene pool by natural selection.
Mutation is the agent of change between individuals of different generations; it is mutation plus natural selection which allows the evolution of anything that's really interesting.

Re: What are the Limits?
We see in red. Infrared is not that much further away in the spectrum, meaning only slight mutations would be required. Other, more advanced species which were already much more specialized (fish and snakes)
Both of which are cold-blooded.
Now there's a big non-surprise.
Presumably since all mutations I've ever heard about are unviable, sterility or death ...
Good grief, the things you don't know.
In order for that to have happened, that means that many countless other thousands per year would've failed.
For example, it is estimated that as many as 50% of embryos fail in the first week or two due to genetic defects. Is that the sort of thing you're thinking of?
Random mutations cannot account for the correct answer without also producing a significantly greater number of failed organisms, and I'm talking like ten million to one. For every viable mutation, there would have be ten million or more unviable ones.
Show your working?
It's not possible that we evolved based on the math alone. And evolutionists always fall back on the concept of "millions and millions of years."
According to evolutionary branches I've seen, less than 10 million years ago some common ancestor between us and apes/monkeys existed. And we are supposed to believe that in only 10 million years (say a 2 year average reproduction cycle (from mother to child), that's 5 million generations max, that this proto creature evolved specifically and directly from what it was to what we see today without not only countless intermediate steps and forms, but rather also the other tens of millions of versions that were unviable and died off.
It's not evidenced by nature as we see today, fossil records, anything. We are what we are, and we reproduce what we are with only the very smallest number of changes.
To think that man in the past 50,000 years has changed any, or even 350,000 years ... is ridiculous - even from the evolutionist's point of view.
You have, evidently, not done the math.
It can be found in the second and third sections of this article.
If you wish to see that in "one paragraph or less", feel free to copy it, paste it, and then remove all the paragraph breaks. Though I think you will find it rather harder to read.
---
I notice that you've gone without so much as a segue from claiming that evolution should produce utter perfection to claiming that it should barely be able to do anything at all.
Might I suggest that the truth lies somewhere between these two utterly incompatible falsehoods?

Re: What about the other guys?
I understand this is the belief, and I say "hogwash."
In order for there to be a beneficial mutation, it would have to be extremely specific. And in order for something specific to happen in an environment of "random mutations," there would have to be an enormous ratio of failed mutations (unviable mutations) to the one beneficial one. I estimated previously 10 million to 1.
Pulling numbers out of your ass is not an "estimate".
I don't see that happening today. I haven't seen one example of mutation on any level which would allow for, in another few hundred thousand years, to move from man or monkey to something nuvo-man or nuvo-monkey, with an additional split in the genetic tree to allow numo-monkey2 or nuvo-man2.
It's an absolute absurdity to think it could happen in so few years, as our evolutionary charts show us today it happened from some proto-hominid about 4-10 million years ago. It's beyond ridiculous actually. The math doesn't add up.
You haven't done the math.
I have.

Re: What are the Limits?
I have never heard of any mutation which shown to benefit the offspring.
Then maybe you should have spent five minutes researching the subject on which you wish to lecture us.
No.
Er, yes it is. You specifically identified "failed" mutations as "unviable" ones. I quote:
In order for that to have happened, that means that many countless other thousands per year would've failed. Random mutations cannot account for the correct answer without also producing a significantly greater number of failed organisms, and I'm talking like ten million to one. For every viable mutation, there would have be ten million or more unviable ones.
And if we go back to the original creatures evolution say existed at some point, the original mammal from which all others developed, then it should've had all kinds of abilities to generate all kinds of what we see today.
No, what you're talking about now is the sort of saltation which the theory of evolution (the one in biology textbooks, not the one you've made up) deems impossible.
Every possible trait should've been produced so that the offspring could go off and find their niche - were evolution true.
Ah, I see we're back to your idea that evolution should be perfect. Only now it should be instantly perfect.
Couldn't you just get your two conflicting strawmen to fight it out while we sit back and eat popcorn?

Re: Implication Of Intelligent Design
I totally agree with your message here. There would have had to be millions if not billions of positive random steps for life to have progressed to the extent of design which we observe today. There's just no random model to support this.
It's called "genetics". You may want to look that word up.
You appear to have some knowledge in the science arena.
No, he's just making stuff up as he goes along.
One of the big disadvantages of knowing damn-all about what you're taking about is that you're unable to tell the difference.
