Re: A four-winged Archaeopteryx?

Longrich's study does bring the 'origin of flight'

I think that this concentration on Archaeopteryx
regarding the origin of flight is arbitrary.
Evolution is bushy, just think about these
Chinese 'dino-birds' with their different kinds
of feathers (vaned, non-vaned, four-winged etc.).
Feathers evolved definitely somewhere outside Aves.
So flight may have originated several times independently
Even Archaeopteryx may be on an sideline regarding
the origin and evolution of modern flight.
So concentration on Archaeopteryx regarding flight
may be something akin to taking a look at one tree
inside a forest without knowing of it's real importance there.
But to make this clear: Archaeopteryx is of course a very important fossil.
