Why do we have a symmetrical body shape like animals?

(A description of evolution as imagined scientifically, based on logic)

Do we not feel that, like animals, we too have a symmetrical body shape? Are we not curious enough to question why the functions of our body and those of the beasts have a lot in common? Thenů, what's the cause behind this?

As has always been the case in man's effort to expand his knowledge, which normally begins with his effort to imagine things on the basis of the limited knowledge he has acquired (from the early people), similarly this paper seeks to explain, by way of imagination, the evolutionary processes that took place within living objects.

That the evolutionists should say that man's body had been undergoing a series of evolutionary changes leads us to believe that when life first began to develop humans-to-be must have still been in an extremely simple form. In their further evolution-particularly after they managed to develop the ability to move around-whenever the body moved forward, the contents of the body would also move (shake). This would have been the time when the body started to be symmetrical.

Now, let's look at something that is very common in our life. Let's fill a hollow glass ball with peanuts, soybeans and corns kernels, then tap it on a flat surface and move it forward, as if it is a living being in motion.


(A) Tapped on the spot. (B) Tapped, and simultaneously moved


After a while, we will find that the contents are casually divided. Now, if we count the peanuts, soybeans and corn kernels on the right part and the ones on the left part, we will find that the numbers are nearly the same.

It is common knowledge that whatever substances there are in human bodies, all these are derived from what exists in nature. Molecules as substances in our bodies are no exception and have, therefore, to abide by all the laws (customs) in effect in nature. Is it possible for things such as exemplified above to occur in human bodies? Although in this example we moved the hollow glass quickly, and in short jumps (so as to speed up the process of what is supposed to be the process of evolution), this movement is, however, not so different from that of a living being. The body matters might indeed shift just a few Angstroms every time the body moves, and this new position (status) is bequeathed to the offspring, which will then shift a few Angstroms further, etc., etc. After billions of years the body might be able to transform itself into a symmetrical living being as it is now.

If this is still not convincing enough, let's apply some figures for the purpose of verification. Since one Angstrom is equal to one ten-billionth of a meter, a living creature, human being in particular, requires a change span of 10,000,000,000 Angstroms to make a one-meter change in its form. Scientists say that man has existed for approximately three and a half billion years, an implication that to achieve a one-meter change from the time he first came into existence until the present time, he needs to change 10,000,000,000 divided by 3,500,000,000, or approximately 3 Angstroms every year. Evidently, however, every time a living creature moves, all parts of its body tend to shift. For example, once it moves its left or right leg forward every part of its body will shift to the left or right. For these parts to get back to their original positions, they have to have total flexibility, which they cannot have. Added to this is the gravitational pull of the earth. It !is estimated that with just each movement, not to mention a year's movement, the parts will shift a few Angstroms from its original position.

In the process of evolution, almost all living beings that can move eventually form a relatively symmetrical body. The left side is symmetrical with the right side. This happens to both humans and animals. It should, however, be noted here that this happens only if the body condition enables such a transformation; otherwise, the separation will not be symmetrical, as is the case with some internal organs of both humans and animals. For example, a human heart is located on the left; the pancreas and colons are also not symmetrical, etc.

Let's take a look at another natural event.

A mixture of sand, sawdust, and fine particles of iron is put into a glass box. At a certain distance and direction, we place a magnet. If we hold the box in a certain position and then rock or jiggle it for some time, the iron particles will clarify what we mean. They will separate themselves from the sand and sawdust, and move towards the magnet. Because the side of the box blocks them, the iron particles will gather on the side that faces the magnet. This gives us reason to say that the iron particles are a matter most sensitive to the influence of the magnet compared to other matters around it.

As there are certain compounds of their bodies that are photosensitive and affected by lights, they too react in a manner as exemplified above. Before these living beings develop the ability to move, it is their upper parts that represent areas most sensitive to lights. This occurs the way it occurs in plants, whose leaves contain chlorophyll and tend to face the sun. In mobile living beings, however, the senses-to-be change their positions as soon as they are able to move around in search for food. The movement by which the mouth is formed is the forward movement. Since the front parts are the ones that experience the most touches, all those that are sensitive are moved to the front part, and these include the eyes-to-be and other senses-to-be.

Because the development of the body functions and the formation of the symmetrical parts occur simultaneously, it is natural if similar body parts with similar functions take a symmetrical form. The eyes, ears, arms, legs, etc. are evidence of the hypothesis regarding this evolution. Since all living creatures are made up of the same basic materials, it is obvious then that not only human beings but also animals have such symmetrical body shapes and body organs as they are today.

Note from the writer

Those who object to these ideas are most welcome to propose the more logical reasons they may have in their minds so that we humans may have a better notion of who we really are.
