A recent “Creation Moments” article is worth reading.
“Anyone who has seen the film Jurassic Park knows that evolutionists have been telling us that modern-day birds are descended from dinosaurs. Well, it looks like the scientists have recently changed their mind.
According to an article on the ScienceDaily website dated June 9, researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight – and the finding means it’s unlikely that birds descended from any known theropod dinosaurs.
The article goes on to report that the conclusions add to other evolving evidence that may finally force many paleontologists to reconsider their long-held belief that modern birds are the direct descendants of ancient, meat-eating dinosaurs, OSU researchers say.
‘For one thing, birds are found earlier in the fossil record than the dinosaurs they are supposed to have descended from,” said OSU professor of zoology John Ruben. “That’s a pretty serious problem, and there are other inconsistencies with the bird-from-dinosaur theories.’…”
Here are some more quotes from the “Discovery Raises New Doubts About Dinosaur-bird Links:
“It’s been known for decades that the femur, or thigh bone in birds is largely fixed and makes birds into “knee runners,” unlike virtually all other land animals, the OSU experts say. What was just discovered, however, is that it’s this fixed position of bird bones and musculature that keeps their air-sac lung from collapsing when the bird inhales.”
“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.”
