The Silkworm, which operates according to a Multi-Stage Plan
It is certain that the beaver is not the only creature in nature that shows the ability to study and plan. There are innumerable living examples in nature of creatures that are much smalle Read more ... r than the beaver and are not expected to show any sign of rational behavior or intelligence in their makeup, yet they perform amazing feats. One such creature is the silkworm. The larva of this insect excretes silken threads. Like all other larvae, this larva spends some part of its life inside the cocoon. When it emerges from the cocoon it hides itself inside a leaf, and this action of concealment is perfectly done, in accordance with a previously worked out plan and in stages which require amazing skill, because when the leaf is green, it cannot easily be folded, and so it cannot easily hide the body of this creature. Hence, a solution to this problem must be found.
This creature has found a simple solution: It bites the edge of the leaf that is attached to the plant, and cuts it, but to prevent it from falling, it ties it firmly with silken threads. The leaf begins to dry up and curl up, and within a few hours the leaf takes on its final shape, and it looks like a tube which forms a safe haven for this creature, which quickly enters it and makes it its home.
Initially, one may think that this creature has taken this logical step to provide itself with a safe place, and this is correct, but when the insect enters this dried leaf, it may become an easy target for others, because the different color of this leaf may attract the attention of birds, which would spell doom for the creature hiding inside it. So, the worm invents something new by means of which it saves itself from the claws of birds. The worm makes precise calculations on the basis of probability principles, similar to the calculations of the most skilled mathematicians. The worm does the same thing with other leaves, and ties these leaves around the one in which it is hiding, as a kind of camouflage against predators. Thus on one branch there will be six or seven leaves, only one of which has the worm hiding inside it, and the rest are empty.
All of these behavioral phenomena are undoubtedly based on specific logic, but is it possible for this worm, which possesses a microscopic brain and a very simple nervous system to perform these premeditated, rational and logical actions all by itself?
If we were to put this question to an evolutionist, he would not be able to give a convincing answer. In most cases he would resort to a single concept, namely instinct, as they explain all animal behavior in terms of instinct. In this case the first question which springs to mind is what exactly is instinct? We can define it as a specific mechanism that makes this worm, for example, conceal itself inside a leaf or makes a beaver build its lodge and dam in this manner. Where is the apparatus that controls this mechanism or motivating force exist within the physical body? No one knows.
