very interesting, I would like to see the take that PZ Myers and Richard Dawkins have on this.

I don't think this really changes the evolution/creation thing. It only questions one of the branches of evolution.

I don't see why the unique lungs and hips couldn't have evolved in birds - obviously at some point birds diverged from other animals and consequently developed unique features, so why is the split necessarily earlier with this discovery?

"For one thing, birds are found earlier in the fossil record than the dinosaurs they are supposed to have descended from," Ruben said.

That sounds an awful lot like the "if we evolved from monkeys, why are there still monkeys" argument.

If you Google John Ruben, you find a lot of stuff on his quest to prove that birds didn't evolve from dinosaurs since at least 2000... I wouldn't take this story at face value.

Wasn't there a flying dinosaur? That one with a long face. Why couldn't they have evolved from that?

Pterosaurs competed with early bird species and were out competed by them to extinction. Birds had already evolved.
