The Bilaterally Symmetrical Forms of Living Creatures


The bilaterally symmetrical forms of all forward-moving living creatures with a symmetrical axis parallel to their forward movement.


Why then are human-beings bilaterally symmetrical?

Surprisingly this particular feature is seen not only in human beings, but also in almost all forward-moving living creatures having axes parallel to their forward movement. Why do they have to be so?

Understandably, the creation of man—a result of the integrated development of the various materials existing in the universe—is one that is inseparable from any of the natural laws imposed upon the whole universe by God. Is it not to be admitted that the basic materials, or the atom’s parts, from which the universe develops, which form atoms when they unite, have been known to posses immense energy, and be capable of moving at a tremendous speed and interminably?

It is as if these basic materials served to provide all living creatures with a source of life (relate this with the discussion on “The Omnipotence and the Omnipresence of God.”). Therefore, there is nothing wrong if we were to try to answer whatever questions concerning the symmetrical form we human beings have by referring to the laws or customs that prevail in this universe. It is as if we were confronted with a problem in our attempt to put, by way of trial and error, the pieces of jigsaw puzzle together. All these naturally requires imagination.

Most forward-moving creatures, either man or animals, have a bilaterally symmetrical form, the axis of which is parallel to their forward movement. This is by no means accidental! One can attribute such orderliness of things to the various laws that God has imposed upon the whole content of the universe as His eternal will.


Let’s say that we are in a position to accept the view of the evolutionists that man’s body were originally very simple in form. Now, with man’s body in such a form as it currently is, there must be some explanations as to how our bodies have managed to maintain its symmetrical form until today. Could it be that the process of change it undergoes is very much in common with the natural occurrences to be described below?


Let’s now take a look at simulation of a condition in nature that have caused a forward-moving living creature to have its symmetrical form. An empty glass ball is filled with 100 grains of peanuts, 100 grains of corn, and 100 grains of rice. The glass ball is then tapped on a flat surface and moved forward, the way a forward-moving living creature would when in motion. After some time, if we were to split the glass ball from back to front into halves, we would instantly see that the number of grains of peanuts, corn, and rice in each half of the glass tends to be the same. (See illustration).


In the illustration above it can be seen that the grains are split up into almost equal numbers: 50 grains of peanuts, 49 grains of corn, and 52 grains of rice in one half of the glass box, and 50 grains of peanuts, 51 grains of corn, and 48 grains of rice in the other half. Is it possible that the transformation of the originally asymmetrical form of the human body into one that is currently symmetrical is a result of such phenomenon? One might perhaps say, “How could someone be so incredible as to identify human beings with such simple things?” Although in the example above the glass ball is moved quickly and in short hops (to speed up the results of what is purported to be a process of evolution), the movement however does not differ much from that of a human being.


The bodily substances may indeed shift by only a miniscule measure of Angstrom each time the body moves, yet such a movement may, billions of years later, cause the human body to become symmetrical, as it is today. It needs to be emphasized here that all this can happen only if the condition of the body makes it possible for such a change; otherwise, the separation will not be symmetrical, as can be seen in a number of internal organs of both man and animals. The heart of a human being, for example, lies more towards the left, while the pancreas and the large intestines are not symmetrical.

          The effects of such bilaterally symmetrical forms as caused by the earth’s gravity is evident in the fact that as one grows older, the shorter one becomes—a result not only of Osteoporosis but, more than that, also of the pressure exerted on one’s body while one is in motion.

In the evolution of a forward-moving living creature there occurs some movements that may result in the combination of similar functions whereby the body tissues are formed, and those that tend to work towards the formation of the symmetrical parts of the body. As both take place simultaneously, it is therefore natural for those body parts with similar functions to have a symmetrical form.

The eyes, ears, arms, legs, etc. can all serve as proofs supportive of this hypothesis on evolution. Should the explanation above still fail to convince the readers, further discussion using figures could perhaps further clarify the point. Now that one Armstrong is equal to one-tenth of a billion meter, a living creature, particularly a human being, would obviously have to undergo a span of change of 10,000,000,000 Angstrom for every meter of change-of-form he achieves.

According to scientists, life first emerged 3.8 billion years ago. Let’s just assume that those man-forming cells-to-be first became multicellulars 1 billion years ago, and since then they have been able to move and have begun to develop symmetrical parts. What this implies is that for the one-meter change he manages to achieve within a period of time extending from the time he first existed to the present time, he would have to undergo a change of (10,000,000,000 divided by 1,000,000,000) or approximately 10 Angstrom every year. Ten Armstrong would, however, seem to be too small a figure if we were to contemplate the illustration given in this page. Yet, it can clearly be seen that every time a living creature moves, all his body parts shift. For example, when he moves his right feet and then his left feet forward, the rest of his body parts move to the right and then to the left. To be able to get back to their original position, these body parts have to be very flexible—something which they just couldn’t afford to be.


It is estimated that with only one—not to mention a year’s—movement the body parts shift to a few Angstrom away from their original position. Please note that the discussions here are confined to only matters concerning conditions that trigger the formation of the symmetrical bodies of forward-moving living creatures. The ability or the habit to move sideways and backwards found in some animals is in fact one that they acquire only after the bilaterally symmetrical form has developed. Unlike forward-moving living creatures, some immobile living creatures such as plants, however, look radially symmetrical.
