Summary
In the evolutionary journey of a living creature, a condition or a movement that occurs continuously from generation to generation, e.g. as when it “moves forward”, will have an impact on the shape of its body.

As we all know, living creatures appear in a variety of forms: some are irregularly shaped, some radially symmetrical, and others bilaterally symmetrical.
Many flowers and plants are radially symmetrical, whereas animals in general, including human beings, are bilaterally symmetrical, meaning that those front parts (see front-view illustration) of theirs will really match up exactly when folded in half.

As it is commonly believed nothing could have possibly occurred in nature for no reason, it must therefore make sense enough for us to say that there must have been a reason behind all these bilaterally symmetrical shapes of animals and human beings. While it is indeed true that such bilaterally symmetrical forms are to be found also in the leaves of a variety of plants, yet animals and human beings—all being forward moving creatures—have their own reasons for adopting such bilaterally symmetrical forms. Let’s go through the explanation that follows:
It is thus not without reason that all forward-moving living creatures with a symmetrical axis parallel to their forward movement have such bilaterally symmetrical forms.

For the common people, who in general tend to take these matters concerning their bodily shape simply for granted, such changes would naturally not seem to be something unusual and worth questioning. Scientists, on the other hand, being the kind of people who always hold that everything exists in nature for a reason, should certainly be in a position to readily maintain that there must be a reason underlying the symmetrical shape of their bodies.

The fact that most forward-moving living creatures (either man or animals) have a bilaterally symmetrical form with the axes parallel to their forward movement 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 was 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 (illustration 3a). 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 3b).

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.
The green broken line indicates the forward movement of a living creature. It is also this very line that represents the axis of its bilaterally symmetrical shape—the only line that divides the creature into two bilaterally symmetrical parts. No other lines could be drawn that would divide the creature bilaterally symmetrical. What this implies is that there is a connection between the forward movement of a living creature, which is here represented by the green broken line, and its bilaterally symmetrical shape. (Illustration 3b).

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?
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. (Illustration 4).
In illustration 4, though man does not move the way a frog does—as represented here by the glass ball—yet, as far as it concerns the division of their bodily molecules (in the course of acquiring their bilaterally symmetrical shape), little difference could be seen between them. The explanation to this is that each time the man /the frog stamps his/its left foot on the ground, all of his bodily molecules move to the left. Similarly, each time he/it stamps his/its right foot on the ground, all of his/its bodily molecules move to the right.

Other explanations related with the bilaterally symmetrical shapes of forward moving living creatures.

Let’s now do a little bit of experiment:

In Illustration 5a, a handful of sand is piled in the form of a cone on a piece of thick paper. Now, if the paper together with the pile of sand is dropped vertically from a low height of, say, 5cm, the sand is seen to scatter in all directions, away from the red dot x.(see lower part of Illustration 5a).
As the red dot x is the spot that receives the strongest pressure when the sand is dropped straight from above, the particles of sand spread in the direction of the red arrows. (See illustrations below, as seen from the top). The spread of the sand resembles the radii of a circle with x as its centre.
In illustration 5b, the pile of sand together with its paper pad is dropped also at a low height, though not exactly vertically down but rather in a slanting position (as shown by the blue arrow). Here, the particles of sand that spread are seen to form an ellipse with the red dot y as the centre receiving the strongest pressure from the top of the pile. The spread is, however, seen to shift somewhat forward. The ellipse formed is not quite one that is perfectly elliptical; rather it looks more like the cross-section of an egg. The back part looks somewhat blunt, while the front part looks somewhat pointed. Explanation for illustration 5b: as a result of the forward movement made simultaneously with the dropping of the pile of sand, the backward spread of the sand is reduced, consequently causing the sand scattering at the back to form a rather blunt shape—very much unlike the back part of the sand in 5a, which is seen to scatter within equal radius, apparently forming a circle. The front part of 5b (see illustration 5b-the lower one), however, becomes somewhat pointed due to the forward force of the whole pile of sand and the pad, consequently causing the frontal-most part of the sand to be thrown further forward.

Now, what can we learn from this experiment? Needless to say, as evident in the way the sand got scattered, it is obviously the forward movement of living creatures as portrayed in Illustration 5b that has resulted in their being bilaterally symmetrical. The left and the right sides of the forward movement—represented by the green arrows--are bilaterally symmetrical.

Thus, even to the molecules of our body, such laws of nature make no exceptions. Each time a living creature moves forward, all of the molecules of its body must move too. And though it is quite possible that the molecules may move in a scale of only a few Armstrong, yet after hundreds of millions of years, the effect can be very significant.

This again confirms that the bilaterally symmetrical shapes that animals and human-beings have are by no means a coincidence. There are reasons which are extremely complex and interlocking underlying such phenomena. Yet, their complexity, there is just no reason for us not to have at least a general idea of where and how such bilaterally symmetrical shapes have come into being.

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 help clarify the point. Now that one Armstrong is equal to one-tenth of a billion meter, a living creature, particularly a human being, will 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 that they have since then been able to move and have begun to develop symmetrical parts. Calculated as of the time when multicellulars began to emerge, because human-beings are made-up of multicellulars.

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. (Illustration 4A and 4B). 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.

As already explained in the previous pages concerning molecular inertia and the jerking of the combined molecules as a result of the movements of the right and the left legs, our bodies will, despite their flexibility, never be able to return to their original position up to a degree of precision of Angstrom. It is here where molecular inertia works to shape the bodies of mobile living creatures such that they become bilaterally symmetrical.

If it is estimated that with only one movement a day the body parts may shift to a few Armstrong away from its original position, one can imagine how large the shift could be in a year’s movement.
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.

In the world of animals, there are also animals that are radially-symmetrical. This type of symmetry is especially suitable for sessile animals such as the sea anemone, floating animals such as jellyfish, and slow moving organisms such as sea stars. The jellyfish could serve as an interesting example: The fact that it moves upwards most of the time explains why its body is radially symmetrical.
What is different about these animals is that they are almost immobile, which consequently could possibly serve to support the claim that animals and human beings have bilaterally symmetrical shapes only because they are forward-moving creatures and that it is this forward movement of theirs that have caused them to become bilaterally symmetrical.

Thus, as exemplified by the glass ball containing a variety of seeds, and also by the pile of sand on the pad being dropped in a forward movement, it can therefore be concluded that the symmetrical shape of a living creature is a result of its forward movement.

Obviously, the molecular inertia has an extremely large share to contribute to the formation of the shapes of all living creatures in general, and of mobile animals in particular.

Because this is something that concerns more about the internal factors of living creatures, its further development could have something to do with Homeobox in Gene, the one related with Hox gene.
This is a possibility that scientists are expected to re-examine.

Certainly all these changes must have been passed on to the descendants. Otherwise every explanation concerning molecular movements that have enabled the body to take a bilaterally symmetrical shape would simply be a waste and irrelevant to the development of evolution.

Conclusion
Those who believe that evolution does occur must certainly believe that before living creatures have such forms as they do today, they must, at the beginning, have been very simple in form. Certainly living creatures must have been in a very simple form before they have their bilaterally symmetrical forms as they do today. In the process of leading to such a change, it has been the laws of nature that have been playing an extremely dominant role.
For this reason, it can be definitely stated here that the bilaterally symmetrical shapes that human beings and all other living creatures have are all ones that they have acquired from the prevailing laws of nature, which, among others, include their forward movement, the earth’s gravity, mass inertia, and limitations in elasticity.
If one should reject the idea that the bilaterally symmetrical shape has been caused by the laws of nature as illustrated above, does one have any other ideas that can serve to explain the causes of man’s and animal’s having such shapes as they do today?
