Author | Topic: Evolution would've given us infrared eyesight | |||||||||||||||||||||||

However, how did we "evolve" cells which detected light in the visible spectrum? Visible light energies are of significantly lower energies than infrared.
As a physicist I would like to point out that in fact the visible light energy range is higher then the infrared energy range.Of course that is secondary to the point that is being made here that the lack of human infrared sight does not detrac from evolution theory either way. Evolution theory does not require that all posiible things will evolve (no matter how advantageous they are)

So if a designer were going to design an optimum human eye:
I can't believe you did not mention the blind spot of the human eye cause by the neuron being bundled towards the inside of the eye(instead of the outside like any intelligent designer would have done) and then puncturing their way out of the eye (gots to get to the brain).

And hey, guess what. You know that stuff that is burning orange and red in this photo:
No, kuresu. That burning orange and red stuff that we pick up in this photo is -- surprise -- orange and red (visible) light.
File:Hot metalwork.jpg - Wikipedia That's the "visible" part of the infrared spectrum that we can pick up.

Science today shows us that it is impossible for Earth to be millions of years old, let alone billions (in anything resembling its present form). Atomic clocks were first activated and used in an official system in 1958. They were set upon two time methods (TAI and UT1) which were roughly in sync with each other at that time. Today some 50 years later, they are 32 seconds apart due to a slowing of the Earth's rotation. A rate of 32 seconds per 50 years yields a slowing of one hour every 5,625 years. Multiply that by 24 (hours per day) and you're sitting at 135,000 years before the Earth would've completely slowed down. Add in a margin of error of 500% and you're now sitting on a maximum of 675,000 years
TGDaily – More than the news I'm curious. You gave us a link that states something entirely different then what you quoted. Did you even read your own link?

Subbie, my position is this: *IF* ToE was true, it would've produced evolution. And we are telling you this: Just because you think evolution ought to have given you IR vision doesn't mean evolution is wrong. There is another logical possibility you have ovelooked. Namely, You don't fully understand the theory. Have you considered this?

RAZD, I have no desire to communicate with you. Please stop responding to my posts.
That's not how things work around here. RAZD is probably you best chance to learn something new while you are here. he is knowledgeable, patient (Much more patient then me), and quite willing to take the time to write high qulity posts. Why would you want to exclude him from the this forum?

They simply use materials which are invisible to infrared light for their receptors.
What? if the IR light is invisible for the receptors, how do the receptors see it?

We can see thermal radiation, it's just that the object has to be hot enough to emit within the range we can see.
Yes, we can see thermal radiation, but that's not what you had said. You said
That's the "visible" part of the infrared spectrum that we can pick up. Infrared radiation and thermal radiation are not synonyms. Infrared is a specific range of electomagnetic radiation (between 750nm and 1000m as you pointed out) defined that way mainly because of the human brain's need to organise its knowlege into neat little boxes. Thermal radiation is not restricted to any specific range, including radio waves, microwaves, infrared, visible,... etc. All the way to gamma rays (yes indeed). Red is the radiation with the smallest frequency (longest wavelength) that we can see. Infrared is just below red -- hence the name -- and is invisible by definition. If we could see it, it would be a new color. lets call it derum (just made that up). whatever invisible radiation whose frequency were to be just below derum's frequency range would be called infraderum. And RickCHodgin would be complained about the fact that (in his views) our inability to see infraderum should be taken as evidence against evolution. That shows how completely irelevant his point realy is. One could always find something else that we don't have or can't do. That is not evidence against evolution. Edited by fallacycop, : typo

According to the list you quote he did, it's covered by #7. I can't believe you did not mention the blind spot

The blind spot is the logical consequence of the nerves lying on the wrong side of the retina.
The retina does not cover 100% of the surface of the eyeball. The nervs could find their way around it. they don't.
Normally we don't notice the blind spot at all.
Sure. But it can be noticed.
On the other hand, I think we would notice the difference if the nerves were suddenly on the backside of the retina, because more photons would reach the retina and that would probably enhance night vision.
I doubt it. But may be you are right.

I think you mean 750nm and 1000m.
