It is scientifically proven that dogs can hear sounds at frequencies inaudible to the human ear. It is also known that their noses can perform up to 150 times superior to the human nose. So? Dogs can smell better and hear better than us. But, would we give up the ability to taste our favorite food, chocolate, wine or sweet? That is an inability all dogs are born with; their tongues serve for nothing more than a cleaning tool. Dogs taste only a variety of tastes, but with their nose. Have you realized when you have a cold and your nose is blocked, your taste buds show to perform far worse than when you are healthy. All of our senses relate to one another and affect one another. Vision is a sense I would never wish to loose, many say it is impossible to live an extreme life without the ability of vision. This may be so, but what about the English skier that recently broke the world record for traveling at 176 miles/hour on skis, with two blind eyes? Our senses do have advantages and disadvantages when one or more are damaged. Loosing one sense does in fact damage our abilities to use that particular sense, but, equally important, it seems to enhance our others. With dogs, it is possible that their inability to use their tongue for tasting could result in their excellent hearing and smelling. Just with the English skier or a bat, the English skier cannot see at all and the vision bats are able to use is at a level said to be useless to the bat. He cannot use his eyes to see where he is moving, nor can bats, yet a bat is known to be an expert flier using sound perception, possibly, the man’s senses may also have enhanced his sound and touch abilities enough to enable him to balance himself at such a velocity.
Clearly, as seen already from dogs, humans and bats, our senses are all perfected to perform better in certain areas. Also, when one area of our senses are damaged, others seem to perform more efficiently. In essence, the biological constitution of a living organism limits, but also enhances certain methods of gaining knowledge.
