The Flea: the Ideal Design for High Jumps

A flea can jump more than 100 times its own body height, which is equivalent to a human jumping 660 feet (200 metres) high. Furthermore, it can continue jumping like this without rest for 78 hours. In general, the flea does not fall onto its legs after the fifth jump, it lands either on its back or head. However, it neither becomes dizzy nor gets injured, which is due to the design of its body.
The skeleton of the insect is not inside its body. It is composed of a hard layer of a compound called sclerotin, which wraps the entire body and is attached to the chitin. Numerous armoured plates with limited movement form this outer skeleton, which absorbs and eliminates the shock of jumping.

On the other hand, fleas do not have any blood vessels. The inside of the entire body floats in a clear and fluid blood, which acts as a cushioning around all the internal organs and makes them immune to sudden pressure jumps. The blood is cleaned by means of air vents scattered throughout the body. This eliminates the need for a giant pump to continually pump oxygen. Its heart is shaped like a tube and beats at such a low rate that the jumps do not affect it at all.
Scientists discovered through research that the leg muscles of fleas are not as strong as the jumps would really require. The extraordinary performance enjoyed by fleas is made possible by a kind of spring system that is added to its legs, which works because of a rubberlike protein called "resilin", where the flea stores mechanical energy. The outstanding property of this substance is its ability to release in stretching up to 97% percent of the energy that is stored in it. The most flexible material in the market today has a ratio of 85%. This elastic material is located at the base of the large hind legs of the animal in tiny pads. The flea takes a few tenths of seconds to compress this material as it folds it s legs in preparation for a jump. A ratchetlike structure holds the leg folded until a muscle is relaxed and the spring-like structure powers the jump through stored energy in the resilin which translates into tremendous leaps.

The Acorn Weevil and its Drilling Mechanism

The acorn weevil which is created with a special "drilling pipe", has an extraordinary reproduction system.	An oak tree and acorns.

The acorn weevil lives on the acorns of an oak tree. There is a moderately long snout on the head of this insect, which is actually longer than its own body. At the end of this snout, it has small but extremely sharp saw like teeth.
At other times, the insect holds this snout horizontal, in line with its body, so that it does not interfere when it walks. However, when it is on an acorn, it tilts this snout towards it. Then the insect looks very much like a drilling machine. It leans the saw-like teeth at the tip of its snout against the acorn. The insect turns its head from one side to the other, moving the snout, which starts to drill the acorn. The head of the insect is of a perfect design for the job and displays an extraordinary level of flexibility.
While drilling with its snout, it also feeds on the fruit inside the acorn. However, it saves the largest portion for its offspring. After drilling, the insect leaves a single egg in the acorn, dropping it there through the hole. Inside the acorn, the egg becomes a larva and starts eating it. The more the larva eats, the more it grows; the more it grows, the more it eats.
This feeding continues until the acorn falls from the branch, which is the signal for the larva that it is time to leave. By means of its strong teeth, it enlarges the hole that its mother made. The extremely fat larva gets out of the acorn with a great deal of struggle. Now the goal for the larva is to tunnel down about 10-12 inches (25-30 centimetres) under the ground. There it goes through pupation and waits for one to five years. When it becomes a full grown adult, it climbs up and starts drilling acorns in turn. The time differential in the pupation period depends on the new growth of the acorns on the tree.50 The interesting life cycle of the acorn weevil is another evidence of the flawless creation of Allah, and it nullifies the arguments of the theory of evolution. Each mechanism of the insect has been designed within a certain plan. The drilling snout, the cutting teeth on the tip, the flexible structure of the head which helps drilling, cannot all be explained solely by coincidences and "natural selection". The long snout would have been nothing more than a great burden and a disadvantage if it weren't successfully used for drilling, which is why it cannot be argued to have evolved "phase by phase".
On the other hand, the organs and instincts of the larva illustrate the "irreducible complexity" of the process. The larva has to have teeth powerful enough to cut its way out of the acorn, has to "know" to dive deep into the ground and has to "wait" there patiently.
Otherwise, the creature could not survive but would become extinct. All of these cannot be explained by coincidence, but show that the creation of these beings displays a superior wisdom.

Allah has created this creature with flawless organs and instincts. He is "the Maker" of everything. (Surat al-Hashr: 24)

The acorn becomes a nest for many other creatures after being used by the acorn weevil. Numerous other insects use acorns during their caterpillar phases and pupation. The acorn weevil uses its head during drilling, just as is shown in the figure.
