The Miracle in the Spider
There are hundreds of species of spiders in the world. These small animals can appear to us sometimes as a construction engineer capable of performing calculations for building its nest, sometimes as an interior designer making complicated plans, sometimes a chemist making incredibly strong and flexible threads, deadly venoms, and dissolving acids, and sometimes as a hunter using the most cunning tactics.
Despite their numerous superior characteristics, nobody in his daily life even bothers to think what special creations spiders are. According to this underestimation there is nothing surprising in the existence of spiders, nor in that of anything else. But this is a completely mistaken way of thinking. Because, as we begin to learn more about spiders, as about the behaviour of all creatures, examining for example their methods of hunting, reproducing, and defending themselves, we find ourselves face-to-face with characteristics that fill us with awe.
In nature all living things adopt behaviour patterns that require intelligence in order to live their lives. These behaviour patterns, that underlie skills, proficiencies and superior planning capabilities, have one thing in common. Each and every one necessarily requires ability. Skills that a human being can master only by learning, and gaining proficiency and experience, already exist in these living creatures from the moment they are born. The later parts of this book consist of questions which need to be answered: how these abilities, which will be described in some detail, came about, and how living creatures learned them. These living things, acting in accordance with such highly intelligent blueprints, hunting with such calculation, and when necessary, behaving like chemical engineers, knowing what material to produce in a particular situation, really baffle scientists who study them. So much so that even evolutionist scientists admit that the cleverest living creatures have characteristics necessitating intelligence. Scientist Richard Dawkins, despite the fact that he is an evolutionist, describes spiders' behaviour in this way in his book, Climbing Mount Improbable:
On our route we shall have occasion to look at spider webs - at the bewildering, though unconscious, ingenuity with which they are made and how they work.
Actually, saying these, Dawkins comes up against such questions as "how the animals' conscious and intelligent behaviour emerged, and what its source was," which cannot be explained in any way by the theory of evolution. Really, questions such as "How do living creatures come to possess this intelligence, and how do they learn where to apply it?" are ones to which the defenders of the theory of evolution are unable to supply open and definitive answers.
At this point an examination of the arguments the evolutionists use to try to answer the question of conscious and intelligent behaviour in animals will be appropriate. Let us do this by explaining the real meaning of a term which evolutionists use in their claims.
Evolutionists searching for an answer to the question of "how living creatures came to have purposeful behaviour" use "instinct" to try to shed light on the matter. But they are in no way successful. This can be clearly seen by a more thorough appreciation of the concept of "instinct." Evolutionists say that animals engage in such things as devotion, planning, tactics or behaviour requiring special abilities, which require consciousness and intelligence, thanks to "instinct." But, of course, evolutionists' just saying this is not sufficient. In addition to making this claim, they also have to provide answers to such questions as how this behaviour first came about, how it was passed down the generations, and how the concept of "instinct" managed to give living creatures consciousness and intelligence. However, evolutionists have absolutely no answers to these questions. Gordon Rattray Taylor is an evolutionist expert in genetics. He has this to say about instincts:
When we ask ourselves how an instinctive pattern of behaviour arose in the first place and became hereditarily fixed we are given no answer.
Other evolutionists say that all living creatures' behaviour is founded not on instinct but on their genetic programming. But in that case they have to explain who wrote the programme and installed it in living creatures. But evolutionists are unable to do this. Despite being the originator of the theory, Charles Darwin admits their dilemma in the following words:
So wonderful an instinct as that of the hive-bee making its cells will probably have occurred to many readers, as a difficulty sufficient to overthrow my whole theory.
As the above makes quite clear, a concept such as "instinct" is absolutely insufficient to shed light on living creatures' conscious behaviour. Of course there is a power that programmes living creatures and teaches them what to do. But this is not a result of "Mother Nature" as it is called, nor of the living creature itself, which will defend its young at the cost of its own life, or which will go back to deceive the enemy with various tactics in order to save the life of another member of its own group.
The power which gives them all these characteristics, which creates their intelligent behaviour and purposeful movements, belongs to God. God is the only lord of that intelligence which we witness in living creatures in countless examples in nature. It is God Who inspires living creatures to do what they do.
It is impossible to explain the behaviour of any living creature by coincidence, or by any other mechanism or interesting concept. No such claim can be any more than a deception. All this is revealed in one of His verses:
Say: 'Have you ever seen your associates whom you appeal to instead of to God? Show me what they have created of the earth; or do they have a partnership in the heavens?' Have We given them a Book whose Clear Signs they follow? No indeed! The wrongdoers promise each other nothing but delusion. (Surah Fatir: 40)
The living creature which is the subject of this book, the spider, its behaviour patterns and the flawless mechanisms it possesses, is one of those that give the lie to the theory of evolution, or, to put it more robustly, "destroy the theory of evolution." The pages that follow will demonstrate one of the countless miracles of God's creation, the spider. At the same time they will once again set forth how the theory of evolution, which relies totally on coincidences, has fallen into impotence and ridicule.
Miracle of Silk
Spiders' thread is five times stronger than steel of the same thickness, and can stretch to four times its own length.
Everybody knows that spiders use silky threads produced from their own bodies in order to spin webs. But the stages of production of the thread and its general features are not so well known. The thread produced by spiders, of a diameter less than one thousandth of a millimetre, is five times stronger than a steel thread of the same dimensions. It can, moreover, stretch to four times its own length. Another striking feature of the silk is that it is very light. We can demonstrate this with an example. A silk thread stretching around the whole world would only weigh 320 grams.
It will be worth having another look at the above technical details. We cannot just gloss over the fact that the silk is five times stronger than steel. Because steel, known for being one of the strongest materials in the world, is an alloy produced in large factories in a series of processes. Spiders' silk, however, five times stronger than steel, is not produced in large factories: it is made by an arachnid. Just about any spider we can see anywhere can produce it. Steel is a heavy material, for which reason it is difficult to use. It is produced in large furnaces at high temperatures and is prepared for use by cooling in moulds. In contrast, spiders' thread is very light. It is produced in the spiders' own small bodies, not in giant furnaces and moulds.
Another miraculous aspect of spider thread is that it is very elastic. It is very difficult to find a material both strong and elastic. For example, steel cables are one of the strongest materials around. But because they are not elastic like rubber, they slowly lose their shape. And although rubber cables do not lose their shape, they are not strong enough to lift heavy weights. On the other hand, as has been described above, spider silk is five times stronger than steel wire of the same thickness, and 30 percent more elastic than rubber of the same thickness.21 To put it in technical terms, spider thread, from the point of view of its resistance to breaking and the extent it can stretch before breaking, is a material the like of which does not exist.
The research into spiders carried out over the last few decades, and the information resulting from it, has brought with it several questions. For example, if mankind makes steel and rubber cables as a result of the knowledge gathered over hundreds of years, then with what knowledge is spider thread, which is so superior, made? How is it that mankind cannot fully grasp the formula and put it into operation? What is it that makes spider silk so superior? The answer is hidden in the construction of the silk. Research by international chemical manufacturing companies has only partially determined the make-up of spider thread.
The Make Up of Silk
The silk spiders make is much stronger than any known fibres, natural or synthetic. When scientists realised this they began experimenting to understand in what way spiders make it. The first ones thought this would be as simple as getting silk from silkworms, but later it dawned on them they were wrong.
Evolutionary zoologist Fritz Vollrath, of Aarhus University in Denmark, realised, as a result of his research, that it would not be possible to make it by taking it directly from spiders. This being the case, scientists then came up with the idea of "the production of artificial spider silk" as an alternative. But, before that, it was necessary for the researchers to find out how the spider produces the silk. This took quite a few years. The zoologist Vollrath discovered an important part of the method in his later work. The spiders' method is remarkably similar to the process used to manufacture industrial fibers such as nylon: spiders harden their silk by acidifying it. Vollrath concentrated his work on the garden cross spider known as Araneus diadematus and examined a duct through which the silk flows before exiting. Before entering the duct, the silk consists of liquid proteins. In the duct, specialized cells draw water away from the silk proteins. Hydrogen atoms taken from the water are pumped into another part of the duct, creating an acid bath. When the silk proteins make contact with the acid, they fold and form bridges with one another, hardening the silk.22 But of course the formation of the silk is not as simple as described here. For silk to emerge, other materials and sacs of various properties are needed.
The raw material of spider silk is "keratin," a protein that appears as braided, helical strands of amino acid chains. This material is also found in hair, horn and feathers. The spider obtains all the raw materials for its silk from a synthesis of the amino acids it secures by digesting its prey. Spiders also eat and digest their own webs, thus producing inside their own bodies the material for further web production.
There is an area at the base of the spider's abdomen where the silk glands are found. Each gland produces different elements. Different types of silk threads are produced from different combinations of the elements from these glands. There is a great conformity between the glands. During the silk production process, specially well-developed pumps and pressure systems within the spider's body are used. The raw silk produced is thrown out in the form of fibres by spinnerets (nozzles) which function like taps. The spider can alter the spray pressure within these spinnerets as it wishes. This is an especially important feature. Because in this way the make-up of the molecules which form the raw keratin is changed. By the use of the control mechanism in the valves the diameter, resistance and elasticity of the thread can be altered while it is being produced. Thus the thread can take on the desired physical characteristics without the need for a change in its chemical composition. If any greater change to the thread is desired, another gland has to come into operation. The resulting tiny silk threads with their many features are then set in the desired way by expert use of the rear legs.
The ratios in which the products of six different glands are mixed are of the utmost importance. For example, when the sticky thread is being produced, if that material which gives the sticky quality is not used in sufficient quantities, it will lose the ability to catch insects. If it is used in too great quantities, the usability of the web will be reduced. For the thread to serve its purpose, the products of the other glands must necessarily be applied at the right level.
The result of these processes being successfully completed is spider silk, with its properties, all different from each other, and able to serve different functions. Spider silk is so strong that Vollrath, the zoologist, describes it in these words: "Spider silk is stronger and more elastic than Kevlar, and Kevlar is the strongest man-made fiber."
And these are not the only special qualities of spider silks. Unlike Kevlar, a kind of plastic used in the production of bullet-proof jackets because of its strength, spider silk can be recycled and used again and again.
The most important point here is that this most perfect product in the world, stronger than steel and more elastic than rubber, is made in the body of the spider. Even the largest textile factories, the most developed weaving establishments, and chemical laboratories fully equipped with the latest technology and researching into atoms have been unable to manufacture anything quite like spider silk. So how did a spider plan such an incomparable chemical make-up? After having planned it, how did it identify the source of the raw materials necessary for production and how did it settle on the six basic ingredients? What measuring equipment did it use to establish the proportions between them?
There is no doubt that all of this could not have come about by chance, as the evolutionists maintain. The spider cannot create a new system within its own body. It is not possible for it first to identify what it will need and then locate them inside its own body. Such an idea is far removed from the realms of science and logic.
It is definitely not possible for a system which produces silks with all their different features to have come about by itself. Such a claim is simply nonsense.
Of course God, Creator of the heavens and the earth, also created the spider and this superb system. God it is Who creates everything flawlessly and Who is aware of all creation.
...He has no partner in the Kingdom. He created everything and determined it most exactly. (Surat al-Furqan: 2)
The Elasticity of Silk Threads
The thread shows different features, depending on what the spider will use it for. For example, the sticky threads are produced in different glands from the dragline and are thinner and more elastic. In some situations they can stretch 500-600 percent.
Spiders have a pump-and-valve system that enables them to make threads. Glandular ducts thicken the substance they exude into a highly vicious state:a liquid crystal, in which the molecules are organized in parallel lines. Strong shearing forces applied to the emergent thread by an extrusion nozzle cause many of the alpha chains to form a stable, tertiary structure, called a beta-pleated sheet.
These protein crystals are in turn embedded in a rubberlike matrix composed of amino acid chains that are not linked into beta-pleated sheets. Instead these helical strands are tangled up in a state of high entropy. It is precisely this randomness that lends silk, like rubber, exceptional elasticity. Stretching the thread pulls the protein strands out of disarray - which they resist - whereas releasing the thread allows them to contract back into blissful disorder.25
The elasticity of the sticky threads makes it possible for flying insects to be gradually brought to a stop. In this way the danger of the web breaking is reduced. The sticky substance used is produced in another group of glands with different functions. This material is so adhesive that it is impossible for insects which get caught in the web to escape.
Threads are Stronger than Steel
The spider's silk is a scleroprotein which is emitted from the spinnerets as a liquid. Scleroprotein is a type of protein that hardens into a tough elastic structure in contact with the air. Thanks to this protein the silk is extremely strong. So strong and resilient has spider silk proved that, on the human scale, a web resembling a fishing net could catch a passanger plane.
Silk's elasticity is balanced by its strength. Because it is a composite material, like glass fibers embedded in a resin, silk is strong. Its crystals and matrix resist breaking. A stretched thread usually snaps because a crack on the surface cuts into it like a wedge. Forces acting along the fiber concentrate at the crack and cause it to rip with increasing speed ever deeper into the material. Such cracks, however, can travel only if they do not encounter resistance. The crystals in the rubber matrix of the spider silk provide obstacles that divert and weaken the rending force.
For something under tension even minor damage to the surface can be dangerous. But this risk is avoided by a precautionary measure in spider thread. While the garden spider spins its silk, it coats it with a liquid material at the same time, in such a way that any cracks that might appear on the surface of the silk are avoided. This method, which spiders have been employing for millions of years, is used in today's industrial cables, which bear heavy loads and need to be very strong.
The descriptions given so far have been technical ones of an existent miracle of construction. But now we must stop and think. What is the truth underlying these technical explanations? It is obvious that the spider is unaware of proteins and the crystal states of the atom. It also knows nothing about chemistry, physics, or engineering. It is a creature bereft of the capacity of thought. But as for the features it possesses, it is impossible for these to be explained by means of chance. But in that case, who is it who makes all these plans and calculations? As we study the spider's web and silk, and its ways of hunting and living, it is immediately clear that it could not have brought about this flawless technical operation all by itself.
Any spider we can see at any moment in a hidden corner or among the plants in a garden is, with its concentration of chemical, physical and architectural capability, yet another clear proof of God's art of creation. In this living creature God is revealing to us His limitless wisdom, His infinite power of creation. It is God Who inspires everything the spider does. God announces this truth in the Qur'an:
Everything in the heavens and the earth glorifies God. He is the Almighty, the All-Wise. The kingdom of the heavens and the earth belongs to Him. He gives life and causes death. He has power over all things. (Surat al-Hadid: 1-2)
The Characteristics of the Jumping Spider
In contrast to many species of spider which spin webs and wait, the jumping spider prefers to attack its prey itself byas the name suggestsjumping on its prey. The spider is so expert at doing this that it can catch a flying insect from more than half a metre away.
The spider can use this amazing technique thanks to the power of hydraulic pressure in its eight legs. At the end of the attack, it suddenly descends on its prey and digs its strong fangs into it. The leap usually takes place between plants in overgrown areas. To do this successfully the spider has to calculate the appropriate angle, together with the victim's speed and direction.
Even more interesting is how the spider manages to avoid being killed after it catches its prey. The spider risks death, because in order to catch its prey, it naturally has to hurl itself into the air. So it could crash back to the ground from this distance (generally from the top of a tree). But the spider avoids this hazard by tethering itself by the thread it spins to the branch it is perched on just before jumping. This stops it from falling and enables it to hang in the air. The thread is strong enough to bear both its own weight, and that of the prey it has caught.
Mission: Locate and Lock on Target
The other physical characteristics of this expert jumping spider species are also impeccable. Two of the eyes in the middle of its head are extended forward like binoculars. These two large eyes can move left and right and up and down in their sockets. Thanks to their retinas of four tiers, which are sensitive to green and ultraviolet wavelengths, the spider's eyes give it excellent distance vision. The other four eyes on the side of its head do not see with the same clarity, but they can sense any movement around them. In this way the animal can easily perceive prey or an enemy behind it.
Let us think about what we have learned about the jumping spider so far. Its bodily construction is such as to enable it to make swift moves, and catch its prey with one jump. In the same way its eyes allow it to see its prey from any direction.
Naturally, the spider did not think that these extra eyes might be useful to it and then make them. And these eyes did not come about by chance. The animal was created, together with its characteristics, by God. The theory of evolution, which cannot explain how even one eye came into existence, is unable to make any comment concerning the jumping spider's eight eyes and the perfect coordination between them.
A Perfect Camouflage Technique in Every Way
If you are asked what you can see in the top right-hand picture, you will naturally say "A few ants on and under a leaf." But the thing waiting beneath the leaf in the picture is not an ant. It is a type of jumping spider known as Myrmarachne. The only way of telling the spider from the ants is by the number of its legs. Because spiders have eight legs and ants six. How is the jumping spider able to deceive the ants? Its does so not just by resembling them in appearance, but also by mimicking their behaviour. For example, in order to disguise the number of its legs, the jumping spider holds up its front pair of legs to simulate the ant's waving antennae.14 In this way they resemble the ants' antennae. At this point we have to stop and think: this means the spider is able to count. The spider has first counted the number of its own legs and those of the ants, and then compared the two. Seeing the difference, it understood that it would have to get rid of them, and in a most conscious manner it made its own extra legs resemble antennae.
There are several points to be borne in mind here. First of all, the spider is physically a completely different creature from the ant. For the spider to look like an ant, it is not enough for it to stick its legs up in the air. It also has to copy the ants' walk and body position. To do this it has to be an expert observer and also be expert at portraying what it sees, like an actor playing a role.
As we have seen, the spider uses methods of imitation, which require thinking, putting its thoughts into action, and realising the necessary physical transformations as it does so. No thinking, intelligent person will find it hard to see that the spider cannot do all this. For one thing, the spider's brain is not capable of that kind of thinking. So, what is the source of the spider's abilities? But before coming to any conclusion, it will be useful to examine some other qualities necessary for the disguise to be complete.
The spider's disguise consists of more than just the above. In order to look like an ant it needs to hide its eyes, which are not single large points, like the ants' are. But a characteristic of the spider has resolved this problem. Two dark spots on the spider's sides mimic the weaver ant's large compound eyes.
Let us stop and think. The spider cannot know about the two spots on either side of its head. It is hardly intelligent to talk about a situation where a spider knows about something and consciously develops a strategy from it. In that case, how did the spider, which lives on ants and mimics them, come by the counterfeit eyes on the side of its head? How did the spider manage to "learn," "count," and "mimic?"
What would have happened if it had not had those false eyes? In that case, no matter how good a mimic the spider was, the ants would identify it. If the ants realised the danger and reacted before the spider did, then that would be the end of the spider. The ants would kill the spider with their powerful jaws. As is obvious, it is not enough for the spider to mimic ants, it also has to have those false eyes from birth for the disguise to be successful.
These are a few of the characteristics which the spider needs to survive. Should one of them be lacking, the jumping spider would soon die. In this case it is impossible to say that the spider came by its characteristics by coincidence. The spider came into possession of all of them at the same time. God has created every living thing in a perfect form, together with every characteristic it will need.
The Devotion of the Jumping Spider
The jumping spider carries its newly born young on its back for a time. In this way it can both meet their needs and protect them better. The spider, which is a pitiless death machine to its enemies, behaves at the same time most affectionately to its offspring. This is a situation which poses many questions for the evolutionists, who claim that there is a struggle for life between living creatures in nature and that only the fittest can survive. But when we examine living creatures in nature, we come across examples in direct opposition to the evolutionists' claims. There are obvious examples of devotion between creatures of both the same and different species. This fact of animals sacrificing themselves for other living creatures, or of risking death for their young, puts evolutionists into an impasse when they look at nature. One scientific magazine describes the position as follows:
The question is why living things help each other. According to Darwin's theory, every living thing is in a constant state of war to preserve its own life and to reproduce itself. Since helping others will decrease the chances of its own survival, this behaviour pattern should have died out in the long term. Whereas it is seen that living things can be self-sacrificing.
It is obvious that it is impossible to explain mother animals' love for their offspring by any evolutionary mechanism. This is such a definite fact that many evolutionists, such as Cemal Yildirim, have had to admit it:
Is there any possibility of explaining love for offspring by any "blind" system that does not include emotional factors (natural selection)? It is certainly difficult to say that biologists, and Darwinists, have been able to give any satisfying response to this question.
Of course it is not possible to explain the concepts of love, compassion and the desire to protect in terms of any "blind" system. Because it is God who inspires all behaviour in animals, which lack consciousness and intelligence. It is not possible for any animal, of its own accord, to demonstrate sacrifice, to prepare plans, or indeed to do anything else. It is God who controls everything.
The Miracle of Creation
We know that spiders are "engineers," making webs, those wonders of architecture and engineering. They are also killing machines, preparing mechanical traps, capable of building nests under water, hunting their prey with lassoos from their webs, capable of giving off chemical poisons, holding on to a thread and jumping from hundreds of times their own height, creating threads stronger than steel within their own bodies, and camouflaging themselves for hunting. We come across further miracles when we examine the structure of their bodies, alongside the properties they possess.
There are many features in all spiders' bodies bearing witness to their having been created, such as combs working like a weaving factory, laboratories making chemical products, organs producing very strong digestive properties, senses capable of perceiving the slightest vibration, strong fangs capable of injecting venom, and so on. Considering all of these properties, the spider gives the lie to the theory of evolution and once again destroys such a derisory hypothesis as coincidence.
Let us examine the organs in the spider and their features.
The spider's body is composed basically of two parts, the combined head and thorax (cephalothorax), and the abdomen. The head and thorax have eight eyes, eight legs, two venom fangs and two feelers. At the tip, the soft and elastic abdomen are spinnerets and holes for breathing systems. The cephalothorax and the abdomen are joined by a small stalk called the "pedicel." No other living creature's waist is as thin as the spider's. Through this narrower than 1mm stalk pass the digestive tract, veins, windpipe, and nervous system. To put it more generally, there is a special linear system joining the two halves of the spider's body. These lines form a link between the splendid mechanisms within the structure of the spider's body (venom glands,silk-producing glands, the whole body's nervous system, breathing and circulation systems) and the brain.
The spider has four pairs of legs enabling it to walk and climb even under the most difficult conditions. Each leg consists of seven parts. At the end of each leg are hairs called "scopula." Thanks to these the spider is able to walk on walls or even upside down.
The special construction of spiders' legs does not stop with allowing it to walk on non-flat surfaces. Despite the fact that their eyes do not see well, the spiders' ability to move about comfortably at night is due to the construction of their legs. Some species of spider can only sense light, or in other words possess only 10 percent of the sight of a human being. But despite this, spiders spin their webs at night and move about easily on them at the same time.
Spiders move about without treading on the sticky parts of the web, only the dry parts. They owe the fact that they are able to escape without getting caught, on the rare occasions that they tread on the sticky parts, to the fact that their feet are coated with a special liquid from their glands. The ends of the combs are known as spinnerets, each of which is covered with hundreds of spigots. The liquid silk produced by the glands in its abdomen is pushed out of the body by these nozzles and then spun in the form of silk.
Superior Sensory Capabilities
With the exception of jumping spiders, most spiders have rather poor sight, and can only see for short distances. This disability, which might be a great disadvantage for a hunter, is compensated for by the spider's particularly sensitive early warning system.
This warning system is based upon the sense of touch. The body is covered with hairs which are very sensitive to vibration. Each one of these hairs is attached to a nerve ending. Vibrations resulting from touch, or even sound and smell, stimulate these hairs. The trembling of the hairs activates the nerve endings. The nerves then rapidly transmit the message to the brain. In this way spiders become aware of even the smallest vibration.
Spiders cannot perceive motionless prey, but by deciphering the vibrations given off by living things, they can work out where the insects are on the web. If the spider is not entirely certain where on the web the insect is, it establishes where the insect has landed by putting its legs on the web, tapping it and making it sway. From the resulting vibrations it can then locate its prey.
The spider's legs are the organs best endowed with these sensory hairs. The hairs are hollow, and of rigid construction. The animal can sense the origin of the vibrations emanating from a source of noise up to a metre away. Furthermore, there is another sensory system sensitive to temperature in the hairs on its legs. Then there are bald spots on the surface of its body with enormously sensitive nerve endings inside. On account of all these properties, spiders can sense any movement going on around them or the approach of any body, even on their own skin.
If a spider loses a leg, it grows a replacement a while later. The new leg will be shorter than the original one. The spider will not use this leg, which does not even touch the ground, for walking. In fact, the spider can walk quite comfortably with only half its original complement of legs, namely four. The only reason for another leg to grow, albeit a short one,is that the spider has need of the sensory hairs on it.
Spiders' sensitivity to vibrations on their webs is so well developed that they can tell whether the source is prey caught on the web or a male spider coming to mate.
Until a few years ago, it was thought that webs, because of their elastic construction, could not transmit vibrations. But research, using the newly developed machines called the "Doppler Laser Vibrometry," shows that the situation is quite the opposite. It is now known that webs conduct vibrations, despite their elastic construction, and that they increase the level of the vibration. However, no scientific reason for this has yet been discovered.
The spider can very clearly perceive any kind of warning, from a tiny sound wave to vibrations on its web. This extremely useful early warning system which passes over the web, is a mechanism having the most useful characteristics from the point of view of the spider. If we consider the fact that each one of the thousands of hairs on the spider's body is attached to a nerve ending and thence to the brain and that the spider can rapidly evaluate the warning signals it receives, the complexity of the system will become more apparent.
Venom Pumping Pangs
The spider has two powerful fangs in front of its eyes. These fangs are weapons the spider uses for hunting and for protection. Behind each fang is a venom gland which pours its lethal poison into a poison hook. When the spider wishes to immobilise its prey, it sinks its fangs into it. Then it pumps venom into its victim's body through holes in its fangs.
Spiders also use these fearsome, deadly tools for building their nests and carrying small objects. To the side of the fangs are two extensions, instead of antennae, called pedipalps (feelers). The spider uses these to examine the victim it has caught in its web.
As we have seen, spiders' sensory systems are of a very special design. It is clear that this system invalidates the claim of the theory evolution of development over time. Alongside this, it is impossible to explain the existence of systems whereby the spider produces lethal poison within its own body by coincidence.
The venom's chemical make-up allows it to kill insects. In order that it should not harm the spider, the venom is stored in a specially insulated area. In the same way the spider's fangs are extremely functional. The venom-pumping mechanisms being located inside the tissue-cutting fangs allows the transfer of the venom into the victim. In this way the fangs work like a chemical, as well as a physical weapon. This demonstrates once again that every part of the spider's body has special planning, which cannot be explained by coincidences, mutations, or any other imaginary evolutionary mechanism.
The spider, together with all its properties, was created by God. All these properties are evidence for us of God's art.
Paralysing the Pray and Digestion
The spider completely wraps the animals which get caught in the web in another thread, which it produces after they become well stuck to the web. Then it takes the prey in its fangs and fills it full of venom, killing it.
The spider can only digest liquids. Tiny particles larger than one-thousandth of a millimetre are filtered out by hairs around its mouth. So, it is necessary for the spider to liquefy this creatures' tissues before it can digest them. For this reason the spider pulls apart the insect's tissues with digestive enzymes. Once the tissues have become fluid enough, it takes in the liquid thanks to its very strong sucking system. For example, after killing a bee, the Misumenoides Formosiges spider opens two holes, one in its head or neck, the other in its abdomen. Then it sucks the juices in the bee's body up through these holes.
The spider mixes the tissues it has sucked up with the digestive juices in its body. When the force of vacuum in the victim's body grows greater than the spider's sucking power, the spider relaxes the sucking muscles around its stomach. This allows some of the digestive juices within the spider's body to enter different parts of the bee's body, where they dissolve the tissues there too. Then the spider sucks through the other hole in its abdomen. The rotation continues until the bee is completely emptied. Beyond simply being a source of food for the spider, the bee's body becomes part of the spider's digestive system, a temporary extension of it. Finally the bee comes to resemble an empty egg shell; nothing remains of it but a shell.
Insects are not spiders' only prey. Frogs, mice, fish, snakes, or small birds can all fall victim to spiders. Spiders known as "bird spiders" are even powerful enough to catch and digest rabbits and chickens.
