Irreducible Complexity

One of the most important concepts that one must employ when questioning Darwinist theory in the light of scientific discoveries is without a doubt the criterion that Darwin himself employed. In The Origin of Species, Darwin put forward a number of concrete criteria suggesting how his theory might be tested and, if found wanting, disproved. Many passages in his book begin, "If my theory be true," and in these Darwin describes the discoveries his theory requires. One of the most important of these criteria concerns fossils and "transitional forms." In earlier chapters, we examined how these prophecies of Darwin's did not come true, and how, on the contrary, the fossil record completely contradicts Darwinism.

In addition to these, Darwin gave us another very important criterion by which to test his theory. This criterion is so important, Darwin wrote, that it could cause his theory to be absolutely broken down:

We must examine Darwin's intention here very carefully. As we know, Darwinism explains the origin of life with two unconscious natural mechanisms: natural selection and random changes (in other words, mutations). According to Darwinist theory, these two mechanisms led to the emergence of the complex structure of living cells, as well as the anatomical systems of complex living things, such as eyes, ears, wings, lungs, bat sonar and millions of other complex system designs.

However, how is it that these systems, which possess incredibly complicated structures, can be considered the products of two unconscious natural effects? At this point, the concept Darwinism applies is that of "reducibility." It is claimed that these systems can be reduced to very basic states, and that they may have then developed by stages. Each stage gives a living thing a little more advantage, and is therefore chosen by natural selection. Then, later, there will be another small, chance development, and that too will be preferred because it affords an advantage, and the process will go on in this way. Thanks to this, according to the Darwinist claim, a species which originally possessed no eyes will come to possess perfect ones, and another species which was formerly unable to fly, will grow wings and be able to do so.

This story is explained in a very convincing and reasonable manner in evolutionist sources. But when one goes into it in a bit more detail, a great error appears. The first aspect of this error is a subject we have already studied in earlier pages of this book: Mutations are destructive, not constructive. In other words, chance mutations that occur in living creatures do not provide them any "advantages," and, furthermore, the idea that they could do this thousands of times, one after the other, is a dream that contradicts all scientific observations.

But there is yet another very important aspect to the error. Darwinist theory requires all the stages from one point to another to be individually "advantageous." In an evolutionary process from A to Z (for instance, from a wingless creature to a winged one), all the "intermediate" stages B, C, D, …V, W, X, and Y along the way have to provide advantages for the living thing in question. Since it is not possible for natural selection and mutation to consciously pick out their targets in advance, the whole theory is based on the hypothesis that living systems can be reduced to discrete traits that can be added on to the organism in small steps, each of which carries some selective advantage. That is why Darwin said, "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down."

Given the primitive level of science in the nineteenth century, Darwin may have thought that living things possess a reducible structure. But twentieth century discoveries have shown that many systems and organs in living things cannot be reduced to simplicity. This fact, known as "irreducible complexity," definitively destroys Darwinism, just as Darwin himself feared.

The Bacterial Flagellum

The most important person to bring the concept of irreducible complexity to the forefront of the scientific agenda is the biochemist Michael J. Behe of Lehigh University in the United States. In his book Darwin's Black Box: The Biochemical Challenge to Evolution, published in 1996, Behe examines the irreducibly complex structure of the cell and a number of other biochemical structures, and reveals that it is impossible to account for these by evolution. According to Behe, the real explanation of life is intelligent design.

Behe's book was a serious blow to Darwinism. In fact, Peter van Inwagen, Professor of Philosophy at the University of Notre Dame, stresses the importance of the book in this manner:

One of the interesting examples of irreducible complexity that Behe gives in his book is the bacterial flagellum. This is a whip-like organ that is used by some bacteria to move about in a liquid environment. This organ is embedded in the cell membrane, and enables the bacterium to move in a chosen direction at a particular speed.

Scientists have known about the flagellum for some time. However, its structural details, which have only emerged over the last decade or so, have come as a great surprise to them. It has been discovered that the flagellum moves by means of a very complicated "organic motor," and not by a simple vibratory mechanism as was earlier believed. This propeller-like engine is constructed on the same mechanical principles as an electric motor. There are two main parts to it: a moving part (the "rotor") and a stationary one (the "stator").

An electric motor-but not one in a household appliance or vehicle. This one is in a bacterium. Thanks to this motor, bacteria have been able to move those organs known as "flagella" and thus swim in water.This was discovered in the 1970s, and astounded the world of science, because this "irreducibly complex" organ, made up of some 240 distinct proteins, cannot be explained by chance mechanisms as Darwin had proposed.

The bacterial flagellum is different from all other organic systems that produce mechanical motion. The cell does not utilize available energy stored as ATP molecules. Instead, it has a special energy source: Bacteria use energy from the flow of ions across their outer cell membranes. The inner structure of the motor is extremely complex. Approximately 240 distinct proteins go into constructing the flagellum. Each one of these is carefully positioned. Scientists have determined that these proteins carry the signals to turn the motor on or off, form joints to facilitate movements at the atomic scale, and activate other proteins that connect the flagellum to the cell membrane. The models constructed to summarize the working of the system are enough to depict the complicated nature of the system.

The complicated structure of the bacterial flagellum is sufficient all by itself to demolish the theory of evolution, since the flagellum has an irreducibly complex structure. If one single molecule in this fabulously complex structure were to disappear, or become defective, the flagellum would neither work nor be of any use to the bacterium. The flagellum must have been working perfectly from the first moment of its existence. This fact again reveals the nonsense in the theory of evolution's assertion of "step by step development." In fact, not one evolutionary biologist has so far succeeded in explaining the origin of the bacterial flagellum although a few tried to do so.

The bacterial flagellum is clear evidence that even in supposedly "primitive" creatures there is an extraordinary design. As humanity learns more about the details, it becomes increasingly obvious that the organisms considered to be the simplest by the scientists of nineteenth century, including Darwin, are in fact just as complex as any others.

The Design of the Human Eye

The human eye is a very complicated system consisting of the delicate conjunction of some 40 separate components. Let us consider just one of these components: for example, the lens. We do not usually realize it, but the thing that enables us to see things clearly is the constant automatic focusing of the lens. If you wish, you can carry out a small experiment on this subject: Hold your index finger up in the air. Then look at the tip of your finger, then at the wall behind it. Every time you look from your finger to the wall you will feel an adjustment.

This adjustment is made by small muscles around the lens. Every time we look at something, these muscles go into action and enable us to see what we are looking at clearly by changing the thickness of the lens and turning it at the right angle to the light. The lens carries out this adjustment every second of our lives, and makes no mistakes. Photographers make the same adjustments in their cameras by hand, and sometimes have to struggle for quite some time to get the right focus. Within the last 10 to 15 years, modern technology has produced cameras which focus automatically, but no camera can focus as quickly and as well as the eye.

For an eye to be able to see, the 40 or so basic components which make it up need to be present at the same time and work together perfectly. The lens is only one of these. If all the other components, such as the cornea, iris, pupil, retina, and eye muscles, are all present and functioning properly, but just the eyelid is missing, then the eye will shortly incur serious damage and cease to carry out its function. In the same way, if all the subsystems exist but tear production ceases, then the eye will dry up and go blind within a few hours.

The theory of evolution's claim of "reducibility" loses all meaning in the face of the complicated structure of the eye. The reason is that, in order for the eye to function, all its parts need to be present at the same time. It is impossible, of course, for the mechanisms of natural selection and mutation to give rise to the eye's dozens of different subsystems when they can confer no advantage right up until the last stage. Professor Ali Demirsoy accepts the truth of this in these words:

What Professor Demirsoy really means by "unimaginably small probabilities" is basically an "impossibility." It is clearly an impossibility for the eye to be the product of chance. Darwin also had a great difficulty in the face of this, and in a letter he even admitted, "I remember well the time when the thought of the eye made me cold all over."351

The human eye works by some 40 different parts functioning together. If just one of these is not present, the eye will serve no purpose. Each of these 40 parts has its own individual complex structure. For instance, the retina, at the back of the eye, is made up of 11 strata (above right), each of which has a different function. The theory of evolution is unable to account for the development of such a complex organ.

In The Origin of Species, Darwin experienced a serious difficulty in the face of the eye's complex design. The only solution he found was in pointing to the simpler eye structure found in some creatures as the origin of the more complex eyes found in others. He hypothesized that more complex eyes evolved from simpler ones. However, this claim does not reflect the truth. Paleontology shows that living things emerged in the world with their exceedingly complex structures already intact. The oldest known system of sight is the trilobite eye. This 530-million-year-old compound eye structure, which we touched on in an earlier chapter, is an "optical marvel" which worked with a double lens system. This fact totally invalidates Darwin's assumption that complex eyes evolved from "primitive" eyes.

The Irreducible Structure of the "Primitive" Eye

It remains to be said that the organs described by Darwin as "primitive" eyes actually possess a complex and irreducible structure that can never be explained by chance. Even in its simplest form, for seeing to happen, some of a creature's cells need to become light-sensitive-that is, they need to possess the ability to transduce this sensitivity to light into electrical signals; a nerve network from these cells to the brain needs to emerge; and a visual center in the brain to evaluate the information has to be formed. It is senseless to propose that all of these things came about by chance, at the same time, and in the same living thing. In his book Evrim Kurami ve Bagnazlik (The Theory of Evolution and Bigotry), which he wrote to defend the theory of evolution, the evolutionist writer Cemal Yildirim admits this fact in this way:

This problem is so great from the evolutionist point of view that the closer we look at the details, the worse the quandary the theory finds itself in. One important "detail" which needs to be looked at is the claim about "the cell which came to be sensitive to light." Darwinists gloss this over by saying, "Sight may have started by a single cell becoming sensitive to light." But what kind of design is such a structure supposed to have had?

The Chemistry of Sight

In his book Darwin's Black Box, Michael Behe stresses that the structure of the living cell and all other biochemical systems were unknown "black boxes" for Darwin and his contemporaries. Darwin assumed that these black boxes possessed very simple structures and could have come about by chance. Now, however, modern biochemistry has opened up these black boxes and revealed the irreducibly complex structure of life. Behe states that Darwin's comments on the emergence of the eye seemed convincing because of the primitive level of nineteenth-century science:

So, how does this system, which Darwin glossed over as a simple structure, actually work? How do the cells in the eye's retinal layer perceive the light rays that fall on them?

The answer to that question is rather complicated. When photons hit the cells of the retina they activate a chain action, rather like a domino effect. The first of these domino pieces is a molecule called "11-cis-retinal" that is sensitive to photons. When struck by a photon, this molecule changes shape, which in turn changes the shape of a protein called "rhodopsin" to which it is tightly bound. Rhodopsin then takes a form that enables it to stick to another resident protein in the cell called "transducin."

Prior to reacting with rhodopsin, transducin is bound to another molecule called GDP. When it connects with rhodopsin, transducin releases the GDP molecule and is linked to a new molecule called GTP. That is why the new complex consisting of the two proteins (rhodopsin and transducin) and a smaller molecule (GTP) is called "GTP-transducin-rhodopsin."

But the process has only just begun. The new GTP-transducin-rhodopsin complex can now very quickly bind to another protein resident in the cell called "phosphodiesterase." This enables the phosphodiesterase protein to cut yet another molecule resident in the cell, called cGMP. Since this process takes place in the millions of proteins in the cell, the cGMP concentration is suddenly decreased.

How does all this help with sight? The last element of this chain reaction supplies the answer. The fall in the cGMP amount affects the ion channels in the cell. The so-called ion channel is a structure composed of proteins that regulate the number of sodium ions within the cell. Under normal conditions, the ion channel allows sodium ions to flow into the cell while another molecule disposes of the excess ions to maintain a balance. When the number of cGMP molecules falls, so does the number of sodium ions. This leads to an imbalance of charge across the membrane, which stimulates the nerve cells connected to these cells, forming what we refer to as an "electrical impulse." Nerves carry the impulses to the brain and "seeing" happens there.354

In brief, a single photon hits a single cell, and through a series of chain reactions the cell produces an electrical impulse. This stimulus is modulated by the energy of the photon-that is, the brightness of the light. Another fascinating fact is that all of the processes described so far happen in no more than one thousandth of a second. As soon as this chain reaction is completed, other specialized proteins within the cells convert elements such as 11-cis-retinal, rhodopsin and transducin back to their original states. The eye is under a constant shower of photons, and the chain reactions within the eye's sensitive cells enable it to perceive each one of these.

The process of sight is actually a great deal more complicated than the outline presented here would indicate. However, even this brief overview is sufficient to demonstrate the extraordinary nature of the system. There is such a complicated, finely calculated design inside the eye that it is nonsensical to claim that this system could have come about by chance. The system possesses a totally irreducibly complex structure. If even one of the many molecular parts that enter into a chain reaction with each other were missing, or did not possess a suitable structure, then the system would not function at all.

It is clear that this system deals a heavy blow to Darwin's explanation of life by "chance." Michael Behe makes this comment on the chemistry of the eye and the theory of evolution:

The irreducibly complex structure of the eye not only definitively disproves the Darwinist theory, but also shows that life was created with a superior design.

The Lobster Eye

There are many different types of eye in the living world. We are accustomed to the camera-type eye found in vertebrates. This structure works on the principle of the refraction of light, which falls onto the lens and is focused on a point behind the lens inside the interior of the eye.

However, the eyes possessed by other creatures work by very different methods. One example is the lobster. A lobster's eye works on a principle of reflection, rather than that of refraction.

The most outstanding characteristic of the lobster eye is its surface, which is composed of numerous squares. As shown in the picture, these squares are positioned most precisely. As one astronomer commented in Science: "The lobster is the most unrectangular animal I've ever seen. But under the microscope a lobster's eye looks like perfect graph paper."356

These well-arranged squares are in fact the ends of tiny square tubes forming a structure resembling a honeycomb. At first glance, the honeycomb appears to be made up of hexagons, although these are actually the front faces of hexagonal prisms. In the lobster's eye, there are the squares in place of hexagons.

Even more intriguing is that the sides of each one of these square tubes are like mirrors that reflect the incoming light. This reflected light is focused onto the retina flawlessly. The sides of the tubes inside the eye are lodged at such perfect angles that they all focus onto a single point.

The lobster eye is composed of numerous squares. These well-arranged squares are in fact the ends of tiny square tubes. The sides of each one of these square tubes are like mirrors that reflect the incoming light. This reflected light is focused onto the retina flawlessly. The sides of the tubes inside the eye are lodged at such perfect angles that they all focus onto a single point.

The extraordinary nature of the design of this system is quite indisputable. All of these perfect square tubes have a layer that works just like a mirror. Furthermore, each one of these cells is sited by means of precise geometrical alignments, so that they all focus the light at a single point.

Michael Land, a scientist and researcher at the University of Sussex in England, was the first to examine the lobster eye structure in detail. Land stated that the eye structure had a most surprising design.357

It is obvious that the design in the lobster eye presents a great difficulty for the theory of evolution. Most importantly, it exemplifies the concept of "irreducible complexity." If even one of its features-such as the facets of the eye, which are perfect squares, the mirrored sides of each unit, or the retina layer at the back-were eliminated, the eye could never function. Therefore, it is impossible to maintain that the eye evolved step-by-step. It is scientifically unjustifiable to argue that such a perfect design as this could have come about haphazardly. It is quite clear that the lobster eye was created as a miraculous system.

One can find further traits in the lobster's eye that nullify the assertions of evolutionists. An interesting fact emerges when one looks at creatures with similar eye structures. The reflecting eye, of which the lobster's eye is one example, is found in only one group of crustaceans, the so-called long-bodied decapods. This family includes the lobsters, the prawns and shrimp.

The other members of the Crustacea class display "the refracting type eye structure," which works on completely different principles from those of the reflecting type. Here, the eye is made up of hundreds of cells like a honeycomb. Unlike the square cells in a lobster eye, these cells are either hexagonal or round. Furthermore, instead of reflecting light, small lenses in the cells refract the light onto the focus on the retina.

The majority of crustaceans have the refracting eye structure. According to evolutionist assumptions, all the creatures within the class Crustacea should have evolved from the same ancestor. Therefore, evolutionists claim that refracting eye evolved from a refracting eye, which is far more common among the crustacea and of a fundamentally simpler design.

However, such reasoning is impossible, because both eye structures function perfectly within their own systems and have no room for any "transitional" phase. A crustacean would be left sightless and would be eliminated by natural selection if the refracting lens in its eye were to diminish and be replaced by reflecting mirrored surfaces.

It is, therefore, certain that both of these eye structures were designed and created separately. There is such superb geometric precision in these eyes that entertaining the possibility of "chance" is simply ludicrious.

The Design in the Ear

Another interesting example of the irreducibly complex organs in living things is the human ear.

As is commonly known, the hearing process begins with vibrations in the air. These vibrations are enhanced in the external ear. Research has shown that that part of the external ear known as the concha works as a kind of megaphone, and sound waves are intensified in the external auditory canal. In this way, the volume of sound waves increases considerably.

Sound intensified in this way enters the external auditory canal. This is the area from the external ear to the ear drum. One interesting feature of the auditory canal, which is some three and a half centimeters long, is the wax it constantly secretes. This liquid contains an antiseptic property which keeps bacteria and insects out. Furthermore, the cells on the surface of the auditory canal are aligned in a spiral form directed towards the outside, so that the wax always flows towards the outside of the ear as it is secreted.

Sound vibrations which pass down the auditory canal in this way reach the ear drum. This membrane is so sensitive that it can even perceive vibrations on the molecular level. Thanks to the exquisite sensitivity of the ear drum, you can easily hear somebody whispering from yards away. Or you can hear the vibration set up as you slowly rub two fingers together. Another extraordinary feature of the ear drum is that after receiving a vibration it returns to its normal state. Calculations have revealed that, after perceiving the tiniest vibrations, the ear drum becomes motionless again within up to four thousandths of a second. If it did not become motionless again so quickly, every sound we hear would echo in our ears.

The ear drum amplifies the vibrations which come to it, and sends them on to the middle ear region. Here, there are three bones in an extremely sensitive equilibrium with each other. These three bones are known as the hammer, the anvil and the stirrup; their function is to amplify the vibrations that reach them from the ear drum.

But the middle ear also possesses a kind of "buffer," to reduce exceedingly high levels of sound. This feature is provided by two of the body's smallest muscles, which control the hammer, anvil and stirrup bones. These muscles enable exceptionally loud noises to be reduced before they reach the inner ear. Thanks to this mechanism, we hear sounds that are loud enough to shock the system at a reduced volume. These muscles are involuntary, and come into operation automatically, in such a way that even if we are asleep and there is a loud noise beside us, these muscles immediately contract and reduce the intensity of the vibration reaching the inner ear.

The middle ear, which possesses such a flawless design, needs to maintain an important equilibrium. The air pressure inside the middle ear has to be the same as that beyond the ear drum, in other words, the same as the atmospheric air pressure. But this balance has been thought of, and a canal between the middle ear and the outside world which allows an exchange of air has been built in. This canal is the Eustachean tube, a hollow tube running from the inner ear to the oral cavity.

The Inner Ear

It will be seen that all we have examined so far consists of the vibrations in the outer and middle ear. The vibrations are constantly passed forward, but so far there is still nothing apart from a mechanical motion. In other words, there is as yet no sound.

The process whereby these mechanical motions begin to be turned into sound begins in the area known as the inner ear. In the inner ear is a spiral-shaped organ filled with a liquid. This organ is called the cochlea.

The complex structure of the inner ear. Inside this complicated bone structure is found both the system that maintains our balance, and also a very sensitive hearing system that turns vibrations into sound.

The last part of the middle ear is the stirrup bone, which is linked to the cochlea by a membrane. The mechanical vibrations in the middle ear are sent on to the liquid in the inner ear by this connection.

The vibrations which reach the liquid in the inner ear set up wave effects in the liquid. The inner walls of the cochlea are lined with small hair-like structures, called stereocilia, which are affected by this wave effect. These tiny hairs move strictly in accordance with the motion of the liquid. If a loud noise is emitted, then more hairs bend in a more powerful way. Every different frequency in the outside world sets up different effects in the hairs.

But what is the meaning of this movement of the hairs? What can the movement of the tiny hairs in the cochlea in the inner ear have to do with listening to a concert of classical music, recognizing a friend's voice, hearing the sound of a car, or distinguishing the millions of other kinds of sounds?

The answer is most interesting, and once more reveals the complexity of the design in the ear. Each of the tiny hairs covering the inner walls of the cochlea is actually a mechanism which lies on top of 16,000 hair cells. When these hairs sense a vibration, they move and push each other, just like dominos. This motion opens channels in the membranes of the cells lying beneath the hairs. And this allows the inflow of ions into the cells. When the hairs move in the opposite direction, these channels close again. Thus, this constant motion of the hairs causes constant changes in the chemical balance within the underlying cells, which in turn enables them to produce electrical signals. These electrical signals are forwarded to the brain by nerves, and the brain then processes them, turning them into sound.

The inner walls of the cochlea in the inner ear are lined with tiny hairs. These move in line with the wave motion set up in the liquid in the inner ear by vibrations coming from outside. In this way, the electrical balance of the cells to which the hairs are attached changes, and forms the signals we perceive as "sound."

Science has not been able to explain all the technical details of this system. While producing these electrical signals, the cells in the inner ear also manage to transmit the frequencies, strengths, and rhythms coming from the outside. This is such a complicated process that science has so far been unable to determine whether the frequency-distinguishing system takes place in the inner ear or in the brain.

At this point, there is an interesting fact we have to consider concerning the motion of the tiny hairs on the cells of the inner ear. Earlier, we said that the hairs waved back and forth, pushing each other like dominos. But usually the motion of these tiny hairs is very small. Research has shown that a hair motion of just by the width of an atom can be enough to set off the reaction in the cell. Experts who have studied the matter give a very interesting example to describe this sensitivity of these hairs: If we imagine a hair as being as tall as the Eiffel Tower, the effect on the cell attached to it begins with a motion equivalent to just 3 centimeters of the top of the tower.358

Just as interesting is the question of how often these tiny hairs can move in a second. This changes according to the frequency of the sound. As the frequency gets higher, the number of times these tiny hairs can move reaches unbelievable levels: for instance, a sound of a frequency of 20,000 causes these tiny hairs to move 20,000 times a second.

Everything we have examined so far has shown us that the ear possesses an extraordinary design. On closer examination, it becomes evident that this design is irreducibly complex, since, in order for hearing to happen, it is necessary for all the component parts of the auditory system to be present and in complete working order. Take away any one of these-for instance, the hammer bone in the middle ear-or damage its structure, and you will no longer be able to hear anything. In order for you to hear, such different elements as the ear drum, the hammer, anvil and stirrup bones, the inner ear membrane, the cochlea, the liquid inside the cochlea, the tiny hairs that transmit the vibrations from the liquid to the underlying sensory cells, the latter cells themselves, the nerve network running from them to the brain, and the hearing center in the brain must all exist in complete working order. The system cannot develop "by stages," because the intermediate stages would serve no purpose.

The Origin of the Ear According to Evolutionists

The irreducibly complex system in the ear is something that evolutionists can never satisfactorily explain. When we look at the theories evolutionists occasionally propose, we are met by a facile and superficial logic. For example, the writer Veysel Atayman, who translated the book Im Anfang War der Wasserstoff (In the Beginning was Hydrogen), by the German biologist Hoimar von Ditfurth, into Turkish, and who has come to be regarded as an "evolution expert" by the Turkish media, sums up his "scientific" theory on the origin of the ear and the evidence for it in this way:

In other words, Atayman thinks that the ear evolved from the ordinary skin in other parts of our bodies, and sees our feeling low sounds in our skin as a proof of this.

Let us first take Atayman's "theory," and then the "proof" he offers. We have just seen that the ear is a complex structure made up of dozens of different parts. To propose that this structure emerged with "the evolution of layers of skin" is, in a word, to build castles in the air. What mutation or natural selection effect could enable such an evolution to happen? Which part of the ear formed first? How could that part, the product of coincidence, have been chosen by natural selection even though it had no function? How did chance bring about all the sensitive mechanical balances in the ear: the ear drum, the hammer, anvil and stirrup bones, the muscles that control them, the inner ear, the cochlea, the liquid in it, the tiny hairs, the movement-sensitive cells, their nerve connections, etc.?

There is no answer to these questions. In fact, to suggest that all this complex structure is just "chance" is actually an attack on human intelligence. However, in Michael Denton's words, to the Darwinist "the idea is accepted without a ripple of doubt - the paradigm takes precedence!"360

Beyond the mechanisms of natural selection and mutation, evolutionists really believe in a "magic wand" that brings about the most complex designs by chance.

The "proof" that Atayman supplies for this imaginary theory is even more interesting. He says, "Our feeling low sounds in our skin is proof." What we call sound actually consists of vibrations in the air. Since vibrations are a physical effect, of course they can be perceived by our sense of touch. For that reason it is quite normal that we should be able to feel high and low sounds physically. Furthermore, these sounds also affect bodies physically. The breaking of glass in a room under high intensities of sound is one example of this. The interesting thing is that the evolutionist writer Atayman should think that these effects are a proof of the evolution of the ear. The logic Atayman employs is the following: "The ear perceives sound waves, our skin is affected by these vibrations, therefore, the ear evolved from the skin." Following Atayman's logic, one could also say, "The ear perceives sound waves, glass is also affected by these, therefore the ear evolved from glass." Once one has left the bounds of reason, there is no "theory" that cannot be proposed.

Other scenarios that evolutionists put forward regarding the origin of the ear are surprisingly inconsistent. Evolutionists claim that all mammals, including human beings, evolved from reptiles. But, as we saw earlier, reptiles' ear structures are very different from those of mammals. All mammals possess the middle ear structure made up of the three bones that have just been described, whereas there is only one bone in the middle ear of all reptiles. In response to this, evolutionists claim that four separate bones in the jaws of reptiles changed place by chance and "migrated" to the middle ear, and that again by chance they took on just the right shape to turn into the anvil and stirrup bones. According to this imaginary scenario, the single bone in reptiles' middle ears changed shape and turned into the hammer bone, and the exceedingly sensitive equilibrium between the three bones in the middle ear was established by chance.361

This fantastical claim, based on no scientific discovery at all (it corresponds to nothing in the fossil record), is exceedingly self-contradictory. The most important point here is that such an imaginary change would leave a creature deaf. Naturally, a living thing cannot continue hearing if its jaw bones slowly start entering its inner ear. Such a species would be at a disadvantage compared to other living things and would be eliminated, according to what evolutionists themselves believe.

On the other hand, a living thing whose jaw bones were moving towards its ear would end up with a defective jaw. Such a creature's ability to chew would greatly decrease, and even disappear totally. This, too, would disadvantage the creature, and result in its elimination.

In short, the results which emerge when one examines the structure of ears and their origins clearly invalidate evolutionist assumptions. The Grolier Encyclopedia, an evolutionist source, makes the admission that "the origin of the ear is shrouded in uncertainty."362 Actually, anyone who studies the system in the ear with common sense can easily see that it is the product of a conscious creation.

The Reproduction of Rheobatrachus Silus

Irreducible complexity is not a feature that we only see at the biochemical level or in complicated organs. Many biological systems possessed by living things are irreducibly complex, and invalidate the theory of evolution for that reason. The extraordinary reproductive method of Rheobatrachus silus, a species of frog living in Australia, is an example of this.

The females of this species use a fascinating method to protect their eggs after fertilization. They swallow them. The tadpoles remain and grow in the stomach for the first six weeks after they hatch. How is it possible that they can remain in their mothers' stomach that long without being digested?

A flawless system has been created to enable them to do so. First, the female gives up eating and drinking for those six weeks, which means the stomach is reserved solely for the tadpoles. However, another danger is the regular release of hydrochloric acid and pepsin in the stomach. These chemicals would normally quickly kill the offspring. However, this is prevented by a very special measure. The fluids in the stomach of the mother are neutralized by the hormonelike substance prostaglandin E2, which is secreted first by the egg capsules and then by the tadpoles. Hence, the offspring grow healthily, even though they are swimming in a pool of acid.

The females of this species hide their young in their stomachs throughout the incubation period, and then give birth to them through their mouths. But in order for this to happen, a number of adjustments have to be made, all at the same time and with no mistakes allowed: The egg-structure has to be set up, the stomach acid must be neutralized, and the mothers have to be able to live for weeks without feeding.

How do the tadpoles feed inside the empty stomach? The solution to this has been thought of, too. The eggs of this species are significantly larger than those of others, as they contain a yolk very rich in proteins, sufficient to feed the tadpoles for six weeks. The time of birth is designed perfectly, as well. The oesophagus of the female frog dilates during birth, just like the vagina of mammals during delivery. Once the young have emerged, the oesophagus and the stomach both return to normal, and the female starts feeding again.363

The miraculous reproduction system of Rheobatrachus silus explicitly invalidates the theory of evolution, since the whole system is irreducibly complex. Every step has to take place fully in order for the frogs to survive. The mother has to swallow the eggs, and has to stop feeding completely for six weeks. The eggs have to release a hormonelike substance to neutralize stomach acids. The addition of the extra protein-rich yolk to the egg is another necessity. The widening of the female's oesophagus cannot be coincidental. If all these things failed to happen in the requisite sequence, the froglets would not survive, and the species would face extinction.

Therefore, this system cannot have developed step-by-step, as asserted by the theory of evolution. The species has existed with this entire system intact since its first member came into existence. Another way of putting it is, they were created.

Conclusion

In this section we have only examined a few examples of the concept of irreducible complexity. In fact, most organs and systems in living things possess the feature. On the biochemical level in particular, systems function by the working together of a number of independent parts, and cannot by any means be reduced to further simplicity. This fact invalidates Darwinism, which tries to account for the design in life by natural influences. Darwin said that "if it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." Today, modern biology has revealed countless examples of this. One can only conclude, then, that Darwinism has "absolutely" broken down.
