Evolution would've given us infrared eyesight

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)

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).

No, kuresu. That burning orange and red stuff that we pick up in this photo is -- surprise -- orange and red (visible) light.

I'm curious. You gave us a link that states something entirely different then what you quoted. Did you even read your own link? Edited by Adminnemooseus, : Off-topic banner.

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?

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?

What? if the IR light is invisible for the receptors, how do the receptors see it?

Yes, we can see thermal radiation, but that's not what you had said. You said 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

#7 covers obstruction of light by intervening blood vessels and nerves. That's barely noticeable. I'm talking about the blind spot which is a bigger issue.

The retina does not cover 100% of the surface of the eyeball. The nervs could find their way around it. they don't. Sure. But it can be noticed. I doubt it. But may be you are right.

You are quite right. I'll fix that typo
