Have you ever thought about “intelligent design” in regards to the human body? We have several spare organs. We have two eyes, two ears, two hands, two arms, two feet, two legs, two kidneys, two lungs, two nostrils and two tonsils. I have omitted a few sets but you get the idea.
We can function with one eye although we would lose the 3-D effect and our depth perception would diminish. We can manage with one ear but less efficiently.
We can function with one hand but with much less efficiency. However, I once knew a man with one hand who could very quickly rope a calf and bind its legs, something I would never attempt with my two hands. It is fantastic how humans can adapt to adversity.
We can live very well with one kidney as evidenced by the many kidney donors.
This does indeed sound like intelligent design, until I start wondering why a lot of these organs which are not necessary to sustain life, come in pairs. They are largely designed for our convenience. Two hands work much better than one, although I am sure most of us have had times when we have thought it would have been more intelligent to have three hands.
On the other hand, most of the organs which are essential to sustaining life only come in a single edition: The stomach, the liver, the pancreas, the digestive tract, the brain and last but not least, the heart. I really do wonder why we have spares for the least important parts and only one of several of the more vital ones?
Think of the benefits of two hearts. It would be much easier and safer for doctors to perform a heart operation. They could stop one heart and repair it without the use of a heart-lung machine. Then they could restart the first heart and repair the second. If one heart was beyond repair they could just remove it, if it was causing problems. We have two kidneys, why not two hearts?
The overall design of the human body is marvelous. We will never fully understand all its inter-workings and life sustaining processes. Yet, there is a glaring flaw which would have been very easy to correct. There have probably been millions of otherwise healthy people who have choked to death. The remedy is simple, have a separate airway to the lungs so food or other foreign material in the throat would not obstruct the air passageway. I am sure there are those who would consider that esthetically displeasing, but if we all had the same design we would never notice it.
Then there are the organs which we seem to be able to do without very well, such as the tonsils, adenoids, wisdom teeth, male breasts and the appendix. They cause problems, sometimes very serious, and we don’t really need them. I admit they may have had uses in the distant past, when our lifestyle was much different.
I also wonder why we don’t have some organs which are available in other species and function with the utmost efficiency. They would provide both pleasure and safety. Some amphibians have both lungs and gills. If humans had gills also, it would make swimming more pleasurable and eliminate most drownings. You would not need a scuba apparatus to go exploring underwater. A variation would be having a permeable skin which absorbs oxygen from the water like some amphibian animals. Information on amphibians was obtained from “Three Types of Amphibians,” on buzzle.com.
I admit the human body operates amazingly well most of the time and I am really glad I have one, but I can’t help wondering about these questions.
