Feathers, which have an extremely complex design and aerodynamic characteristics, are unique to birds. The claim that bird feathers evolved from reptile scales is completely groundless.
The bodies of reptiles are covered with scales, whereas the bodies of birds are covered with feathers. Since evolutionists consider reptiles the ancestors of birds, they are obliged to claim that bird feathers have evolved from reptile scales. However, there is no similarity between scales and feathers.
A professor of physiology and neurobiology from the University of Connecticut, A.H. Brush, accepts this reality, although he is an evolutionist: "Every feature from gene structure and organization, to development, morphogenesis and tissue organization is different (in feathers and scales)."36 Moreover, Prof. Brush examines the protein structure of bird feathers and argues that it is "unique among vertebrates."37
There is no fossil evidence to prove that bird feathers evolved from reptile scales. On the contrary, "feathers appear suddenly in the fossil record, as an 'undeniably unique' character distinguishing birds" as Prof. Brush states.38 Besides, in reptiles, no epidermal structure has yet been detected that provides an origin for bird feathers.39
The "Feathered dinosaur fossils discovered in China" story, which came to light in 1996 amidst great media propaganda was totally unfounded, and it was realised in 1997 that the Sinosauropteryx fossil in question possessed no structures resembling feathers.40
On the other hand, when we examine bird feathers closely, we come across a very complex design that cannot be explained by any evolutionary process. The famous ornithologist Alan Feduccia states that "every feature of them has aerodynamic functions. They are extremely light, have the ability to lift up which increases in lower speeds, and may return to their previous position very easily". Then he continues, "I cannot really understand how an organ perfectly designed for flight may have emerged for another need at the beginning".41
The design of feathers also compelled Charles Darwin to ponder over them. Moreover, the perfect aesthetics of the peafowl's feathers had made him "sick" (his own words). In a letter he wrote to Asa Gray on April 3, 1860, he said "I remember well the time when the thought of the eye made me cold all over, but I have got over this stage of complaint..." And then continued: "... and now trifling particulars of structure often make me very uncomfortable. The sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick!"42
