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
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.
