Origin of birds flight, in which developing wing structures served as a sort of parachute. Second, they achieved active flight by flapping the wings. He used "Archaeopteryx" as an example of this second stage. Finally, birds gained the ability to soar. Current thought is that feathers did not evolve from scales, as feathers are made of different proteins. More seriously, Nopcsa's theory assumes that feathers evolved as part of the evolution of flight, and recent discoveries prove that assumption is false. Feathers are very common in coelurosaurian dinosaurs (including the early tyrannosauroid "Dilong"). Modern birds are classified as coelurosaurs by nearly all palaeontologists,
