Re: A four-winged Archaeopteryx?

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
inside/outside Aves.

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.
