Evolution of the eyes

Post by Crimson11 » Tue Jul 19, 2005 8:45 am

Is it possible for the naked human eye to see (through some sort of genetic mutation maybe?) beyond the normal visual Em spectrum, even if in the slightest?

Yes... the "normal" (whatever normal is) human eye can only see a VERY small part of the electromagnetic spectrum

I was just wondering if it is at all possible for the naked human eye to see beyond the regular visual range

Do you know how the human eye works? The complex biochemical reactions are all trigered by a chemical substance called retinal(or retinen in older books) which goes from CIS to TRANS state. Thus, for the eye to see more, you would have to replace retinal with a "better" substance

No I didn't know that but now I do, thank you.

Almost all of my knowloge lies in physics, so I'm here to learn.

We are all here to learn and understand so never be afraid to ask anything :wink:
