Answer is probably yes. Recently, it has been suggested that Archaeopteryx may have had reptilian physiology, that would allow powered takeoff. This suggestion is based on the differing physiology between reptile and bird muscle and the differing morphology of the pectoral girdle and muscles used for takeoff in Archaeopteryx and modern birds. The upstroke is presumably then powered by the deltoids, and a prominent acromion process may serve as the attachment for these muscle to the humerus. This hypothesis argues that birds arose from Pseudosuchians directly at least 200 mya.
Similarities are just retained primitive characteristics.
However, proponents argue that they may have shared a common ancestor. Flight feathers thought to have evolved to maintain stability while leaping. Even a small amount of lift would greatly increase stability. Flapping flight evolves as a continuation of this trend. Wing morphology very different from gliding structures in other animals.
