Umm--does this amount to a recanting of BCF?
Many avian dinosaurs of comparable size to the non-avians also lack
wings, you know.
Yes, flight may amount to a functional difference between many avian
dinosaurs and non-avians, but anatomically, the structure of
_Deinonychus_'s hand, for instance, is far more similar to that of a
bird's wing than to the forefoot of _Apatosaurus_.
What's wrong with seeing birds as just another twig on the bush, as just
another example of the broad variety of dinosaurian form and function?
