The feathers of other bird species have sharp edges, while owls' feathers do not. This enables the animal to fly and hunt at night, completely silently.
According to a statement by scientists at NASA's Langley Research Center, the soft edges of an owl's feathers prevent air turbulence, that in turn prevents noise. When looking for ways of making ghost planes fly through the sky without being detected, military designers copied the owl feather's structure.At the world's busiest airports, planes land and take off roughly every two to three minutes during the day. Airway traffic of this density is controlled by leaving between planes a distance of 4 to 5 km (2 to 3 miles). This minimum security distance needed is determined by such considerations as the size of the plane and its maneuverability.
Yet birds fly in huge flocks, with a far greater density than that of airplanes in formation. How do hundreds of creatures fly with such control and safety at the same time?
Consider the plover, which lives in coastal areas. The "safety gap" for this species is only a few lengths, yet the birds fly at more than 30-40 km (18-25 miles) per hour. Despite that speed, however, they are able to take off and land with ease.
This superior flying ability requires a special engineering calculation, which aircrafts have not yet been able to achieve. Long years of research have produced some high-maneuverability planes, such as helicopters that can hang suspended in the air and land and take off vertically. Yet these machines' flying abilities and maneuverability come nowhere near to those exhibited by living things.
The structures in the bodies of living things are far superior to those we humans have designed. This perfection can be clearly seen when we consider just the example of wings.
How did these incomparable designs come about? Why is it that the owl has silent wings that lets it hunt at night, and not the noisy wings of a pigeon or a swan? How does the pit viper locate its prey at night by using its infrared sensor? Who placed all these complex systems— which our human engineers now strive to duplicate—in the bodies of living things?
Evolutionists answer such questions by supposing that living things acquired their present characteristics through accidental genetic changes in their bodies over time, in other words, by "gradual change." Yet this claim is meaningless when considered in the light of logic and reason, as well as the scientific facts. It is impossible for cells to have come about by chance and then, of their own accord, to have combined to form such flawless structures. This is just as irrational and illogical as claiming that giant skyscrapers or bridges came into being by accident.
It's impossible for even one of the billions of cells that comprise the bodies of living things to have arisen by chance. The cell's structure is so complex that it cannot be reproduced even with today's technology. All attempts to create an artificial cell have ended in failure. Countless similar examples of design in nature reveal the evident truth that God, the Lord of infinite might and knowledge, designed all living things right down to their tiniest details, in an incomparably perfect manner. Evolutionists find themselves in a position that needs to be weighed more carefully.
The presence of perfect technologies in the bodies of a tiny insect, fish, or bird, far superior to those planned by man, reveals proof that they were created. These unique designs in nature are the work of Almighty God, Who in one verse reveals:
Say: "Who is the Lord of the heavens and the Earth?" Say: "God." Say: "So why have you taken protectors apart from Him who possess no power to help or harm themselves?" Say: "Are the blind and seeing equal? Or are darkness and light the same? Or have they assigned partners to God who create as He creates, so that all creating seems the same to them?" Say: "God is the Creator of everything. He is the One, the All-Conquering." (Surat ar-Ra'd: 16)
