The bones of our bodies and those of a number of other animals can be moved at the joints. Certain muscles contract whilst others simultaneously expand in harmony, and the hand, leg, finger or other part of the body moves in the way in which the person or animal wants it to move. The joints are formed in such a way that they are able to slide, so the creature does not feel any friction.

The vertebrae of the spinal column are joined in a way that is designed to take pressure and avoid friction. The vertebrae are connected to one another, and it is an amazing design. The spinal column encloses the spinal cord to protect it just as the skull protects the brain inside it, and nerves extend from the spinal cord through holes in the vertebrae. All these design features have to have happened at the same time, because if even one aspect of this design was lacking, the animal would not be able to move. Does it make sense to suggest that all of these features could have happened at the same time as the result of an accident?

It is well-known that if we are wounded, the blood which comes out of the veins at the site of the wound quickly clots. There is a reason behind this. The congealed blood seals the wounded blood vessels, thus stemming the flow of blood. If this clotting did not happen, the individual would bleed to death.

What it indicates is that a deliberate plan on the part of the Creator to protect living beings is the fact that we find it happening in different ways in different creatures. The result in all cases is the same. In most insects, if the insect such as a cockroach, for example, is wounded, a number of cells gather and form a seal over the wound so that no blood can come out. In some insects we find that the blood clots just as our blood does.

The fact that the same goal is reached by different means, as we have stated above, offers definitive proof of the existence of a Creator Who controls and designs things in different ways in order to reach a specific goal for which He keeps the living being alive.

It cannot be accidental that the sensory antennae of the male mosquito have longer hairs than those on the antennae of the female. In the past, it was believed that these longer hairs served as an adornment, to make the male attractive to the female. But it then became apparent that these hairs of the antennae of the male mosquito are able to pick up special sounds made by the female from a great distance. These sounds made by the female travel by waves which, to a large extent, resemble the waves of a broadcast.

The male waves his antennae in different directions just as we move the antenna of a television in order to get a clearer picture. In certain positions the antennae pick up the female's sound clearly, and from the angle of his antennae, he knows instinctively where the female is who is making the sound. So he flies towards her, taking the shortest route, in order to mate with her.

Thus we note that the Creator has given the mosquito this amazing ability to detect the female's sound from dozens of meters away, despite the fact that there are many other sounds crowding the airwaves. If this did not happen, the male mosquito would not be able to find the female easily, and mosquitoes would not be able to survive generation after generation.

This is like a broadcast receptor in the mosquito's antennae which it used millions of years before man was able to discover the secrets of wireless communication. Is it possible that such a thing could have happened as the result of blind chance?

The females of some species of insects flash in the darkness, with a frequency which is distinguishable to the males of the same species and which they do not confuse with the flashes of other species which are emitted on a different frequency. When the male sees these flashes, which are barely discernible to our eyes, he flies to the female and mating takes place, thus ensuring the continued survival of the species.

Mathematics proves that a system of this kind could never be formed by the blind and unreasonable forces of "nature." It is a system devised by a Creator Who knows what He is doing and Who orders things in the most amazing fashion in order to achieve a certain goal.

We know that it is essential to cut food into small pieces to make it easy to digest. The teeth have different structures and are arranged differently in different animals in order to perform the same function, which is cutting up food.

In man, the teeth are arranged in an amazing fashion. We see that man has incisors, canines and molars, arranged in such a fashion that each kind of tooth performs a specific function. Animals do not have any kind of teeth that they do not need. Animals which feed on liquids are equipped with special means of sucking up their liquid food and conveying it to the digestive tract. When animals, which have teeth, chew, the secretions of their salivary glands mix with the food to initiate the digestive process.

In the stomach and intestines — as we have mentioned above ---- the animal produces enzymes, each of which work on a certain kind of food and have no effect on others.

The development of the embryo in any kind of animal is something amazing. Science is only able to describe the stages in this process; it is incapable of explaining its nature and the forces which push it towards a specific goal, namely the formation of the embryo of a given animal.

This process begins with the joining of the male cell (sperm) to the female cell (egg), to form the fertilized cell. The fertilized cell then begins to divide by means of an amazing force which resides in it, so the cell becomes two cells, then four cells, then eight cells, and so on... until the number of cells reaches a specific limit, and it becomes like a hollow ball, the wall of which consists of a single layer of cells. Then half of the ball goes inside the other half, making two layers of cells in the wall.

In most animals including man — a third layer of cells forms between these two layers. The cells continue to divide, and each of these three layers develops into specific organs.

The outer layer develops into the skin and nervous system, and some other parts. The middle layer develops into muscles and bones. The inner layer develops into part of the digestive tract. The cells continue to divide until the foetus is fully formed inside its mother's womb, in mammals, or inside the egg, if it is an egg-laying animal. When the foetus is fully formed, the uterus of the mother expels it, in the case of mammals, or it breaks the egg and emerges, in the case of animals which lay eggs.
