Vision

Natural History of the Senses- VISION

Like the book explained, often times when we look into the sky and see

emptiness, there are actually billions upon billions of things that are happening right

in front of our very eyes.  Due to restrictions in our brain  and vision function, we

are only able to consciously visualize a certain frequency of visual information.

Imagine a boy who is standing at the edge of a pond observing all of the animals and

organisms that live in the ecosystem.  To the boy, each organism and animal

observes the external world the exact same way he does.  However, this is not the

case.  The fish at the bottom of the pond, the tadpoles resting on top, and the birds

flying over the water all have different levels of visual processing in their brains.

Therefore, each one of these organisms views the world in a unique way that we are

unable to ever fully understand.  Our vision may be precise and accurate, but there

are many other animals that exist in the world that have exceptional vision

compared to humans.  For example, some birds are able to fly hundreds and

hundreds of feet above sea level while still being able to locate prey beneath the

water.  Clearly, some animals have increased their visual perception and awareness

due to biological adaptions.  Attached is an article explaining how different species

view the world.
