There are thousands of bird species on the earth. Every one of them possesses distinct features. For example, falcons have acute vision, wide wings and sharp talons, while hummingbirds, with their long beaks, suck the nectar of flowers.
Others migrate over long distances to very specific places in the world. But the most important feature distinguishing birds from other animals is flight. Most birds have the ability to fly.
How did birds come into existence? The theory of evolution tries to provide an answer with a long scenario. According to this story, reptiles are the ancestors of birds. Approximately 150-200 million years ago, birds evolved from their reptile ancestors. The first birds had very poor flying skills. Yet, during the evolution process, feathers replaced the thick skins of these ancient birds, which were originally covered with scales. Their front legs were also completely covered by feathers, and changed into wings. As a result of gradual evolution, some reptiles adapted themselves to flight, and thus became the birds of today.
This scenario is presented in evolutionary sources as an established fact. However, an in-depth study of the details and the scientific data indicates that the scenario is based more on imagination than reality.
