    You mean all previously known "facts" of evolution might not be so factual???

    Ill be..:wink2:

    As has been said before nature often comes up with similar solutions or adaptations to the same environmental necessities .

    For instance eyes were independently developed by crustaceans,animals ,birds etc.Not all creatures have eyes.Some have not needed them.

    So it could be that birds developed features that were similar to the features of the flying dinosaurs such as lightweight hollow bones but that they evolved independently.

    How did you come to that conclusion? That is quite a leap, my friend. :wink2:

    just remember. evolution is not a theory its a fact, an ever evolving fact that never gets bogged down in messy things like proof. Not evolved from dinosaurs, no problem, my bad. couldve been worse. we couldve said God created them lol.

    Funny.

    I don't think you should be calling something out about facts, when you say God created everything. Its fine if you do. All power to you. But obviously with the conclusion you've come to, facts weren't all that important to you.:up:

    just having some fun. Creationists have mocked the link of dinosaurs to birds for awhile now only to be laughed at by the scientific crowd. Seems the bible thumpers got this one right :yes:

    Love this part of the article

    "This is fundamental to bird physiology," said Devon Quick, an OSU instructor of zoology who completed this work as part of her doctoral studies. "It's really strange that no one realized this before. The position of the thigh bone and muscles in birds is critical to their lung function, which in turn is what gives them enough lung capacity for flight."

    However, every other animal that has walked on land, the scientists said, has a moveable thigh bone that is involved in their motion – including humans, elephants, dogs, lizards and – in the ancient past – dinosaurs.

    The implication, the researchers said, is that birds almost certainly did not descend from theropod dinosaurs, such as tyrannosaurus or allosaurus. The findings add to a growing body of evidence in the past two decades that challenge some of the most widely-held beliefs about animal evolution.


    "For one thing, birds are found earlier in the fossil record than the dinosaurs they are supposed to have descended from," Ruben said. "That's a pretty serious problem, and there are other inconsistencies with the bird-from-dinosaur theories.

    "But one of the primary reasons many scientists kept pointing to birds as having descended from dinosaurs was similarities in their lungs," Ruben said. "However, theropod dinosaurs had a moving femur and therefore could not have had a lung that worked like that in birds. Their abdominal air sac, if they had one, would have collapsed. That undercuts a critical piece of supporting evidence for the dinosaur-bird link.

    "A velociraptor did not just sprout feathers at some point and fly off into the sunset," Ruben said.

    Not unlike cancer. ;) We know it is real because the evidence of it is all around us but our understanding of it continues to grow.

    As for "proof", it has been offered many times in this and other forums but what constitutes "proof" seems to be a moving target for many.

    Just as "facts" are for the other group. The dinosaur to bird evolution was cited as fact and proof of evolution in other threads. The sceptic side said there was no proof. Seems the cynics won this round
