Why does our visual range stop outside the 400-700nm (approx) wavelength range of light? Are there people or animals who have a greater range than this? I have heard that some insects (bees to be precise) can see in the ultra violet and infa-red range.

Is it biologically impossible to see beyond this or is it just the result of evolution cutting out any wavelengths that would not be of any use to us? Can we see the full spectrum of light but our brains filter out anything that isn't in this range? Any web references would be very useful.

The objective of this question is to generate insights of how this problem could be solved using collective mankind´s knowledge.
The greatest cientist of our history didn´t solve this question yet, but now the Internet provide us a platform where colaborative knowledge share between schoolars and common people can give us a better chance to actieve this goal.

Do you believe in these Paranormal (PSI related)events?
I'm not talking about television.
Have you ever seen "PSI Factor" TV show? It is still on in Iran.well. I follow it every week and it's the best TV show I have seen ever.all about strange events.my favourite things.But do you think they have actually happened?Some of them are just hard to believe.I have heard of getting older but I haven't ever heard of getting younger untill you are only six! Are there any proofs on any of them?Were really 10 stors of a skyscraper in the U.S disappeared?If so why haven't we heard about them on news?Could such important events be hidden?Why 99% of U.F.Os are just seen in the U.S?Don't tell me because little green aliens have fallen in love with Americans!cos they haven't.because movie makers in Hollywood want it to be that way!(But to be honest I saw one of these strange objects over Iran's sky at dawn and I live in the northern part of Iran right in the cat's head so it couldn't have been a satellite but I could be wrong) I believe in the other world,miracles,strange powers of mind, and lots of other things.But that doesn't mean that I should believe aliens have abducted a man so he could talk to live cells and he could change his figure or a statue is looking for his lost head or the earth was going to be sawallowed by an unknown darkness!Tell me have any of you ever seen or heard of an area in a jungle which can turn you to a 70 year old man within seconds?If it was true then government should have warned people not to go there!It's too stupid.But as I said some of them are quite believable such as seeing ghosts,U.F.Os,U.S.Os,using your mind to do strange things,telepathy and so on. NOT ALL OF THEM.They claim ALL these stories are based on actual case files of O.S.I.R reaserchs and they have actually happened.(O.S.I.R stands for the Office of Sientific Investigation and Research and I don't know if it is in the U.S or in Canada) Could science explain them?Do you believe in them?
Read this part if you don't know what O.S.I.R is otherwise please answer the question.
The Office of Scientific Investigation and Research - the O.S.I.R.- is a private organization that, among its many activities, scientifically explores incidents which might be paranormal in nature. These include such areas as haunting and poltergeist phenomena, possessions, exorcisms, miracles, psi-related phenomena (including psychokinesis, precognition, altered states, near-death experiences and channeling), geophysical mysteries, astral projection, reincarnation and telepathy.
By the way you can find all stories of "PSI Factor" episodes in it's official websie.
