Evolution Differs
Evolution Differs
Evolution hasn’t ordered living creatures in a straight line from crude sight — as we humans would judge it — to more evolved sight, meaning our own. Many birds, insects, and fish are tetrachromatic, so that some spiders and birds can see ultraviolet, which humans cannot. This would make insect prey glow green in the dark. The reason that we cannot see UV is that our lens blocks it from striking the retina, but people whose lenses have been removed in a cataract procedure or who were born without a lens (aphakia), have been reported to detect UV light.
No Normal Way
As evolution has developed different sensory systems, reality shifted.There is no ‘normal’way to decode photos of invisible light. Pigeons and some butterflies are actually pentachromats; in theory, such creatures could distinguish up to 10 billion colours even though we have no way to prove this. The mantis has 16 different receptor types, including four types of receptors just for seeing UV light, and four others for polarised light. A human would need many distinct kinds of sunglasses to duplicate the sensation. Many snakes can also ‘see’infrared, or heat radiation, using special detectors that send thermal information through their visual system...
What The Eye Cannot See
It’s hard to escape our assumption that eyesight connects us to the real world, but every living thing is connected to a created world.The question of matching our creation to a possible ‘real reality’ will come next. The conclusions of quantum mechanics will certainly have to be brought in. For the moment, we need to realise that the world created by other species is inconceivable to us….
