Origin of avian flight Origin of avian flight Around 350 BCE, Aristotle and other philosophers of the time attempted to explain the aerodynamics of avian flight. Even after the discovery of the ancestral bird "Archaeopteryx" over 150 years ago, debates still persist regarding the evolution of flight. There are three leading hypotheses pertaining to avian flight: Pouncing Proavis model, Cursorial model, and Arboreal model. "Archaeopteryx", the oldest known ancestor of modern birds, could provide clues to the origin of avian flight. In March 2018, scientists reported that "Archaeopteryx" was likely capable of flight, but in a manner substantially different from that of modern birds.
Specimens of Archaeopteryx under his control and full exposed, his subsequent study and monograph was the first comprehensive description of an "Archaeopteryx" specimen that had not been disarticulated. The Berlin specimen of "Archaeopteryx" is to date the most complete existing specimen of this genus, and is widely regarded as one of the most beautiful fossils in the world. Its well-preserved skeleton and the preserved feathers of its wings and tail have made it of considerable interest to a wide range of scientific study, beginning with Wilhelm Dames and Carl Vogt shortly following its discovery. This iconic fossil preserves the animal with an articulated
