Q: Did birds evolve from dinosaurs?

A: The notion that theropod dinosaurs evolved into birds has almost certainly become one of the most widely accepted “facts” of evolution. The question for many evolutionary researchers had transitioned from “if” to “how.” Even artists’ depictions of some dinosaurs (such as velociraptors) began to include feathers. Except for a few notable critics, such as University of North Carolina paleobiologist Alan Feduccia, evolutionists seem to have all but agreed on birds’ dinosaurian origins.

Now, a new paper in the Journal of Morphology presents the research of two Oregon State University scientists who don’t agree with the evolutionary dogma on bird origins. Doctoral student Devon Quick conducted the investigation into bird breathing and its connection with dinosaur-to-bird evolution as part her dissertation.

The research hinges—almost literally—on the femur (upper leg bone) of birds. Unlike other walking creatures, a bird’s femur does not move significantly, and birds instead articulate the lower portion of their leg to walk or run. Quick’s surprising discovery is that this “knee running” anatomy, with nearly fixed femur bones and musculature, is crucial in preventing a bird’s air-sac lung from collapsing whenever the bird takes a breath.

Quick explained, “This is fundamental to bird physiology. 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.”

Dinosaurs lack this fixed femur, however, and that includes the theropod dinosaurs from which birds supposedly evolved. Oregon State zoologist John Ruben, a coauthor on the paper, commented, “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.”

News to Note Quick Look

Birds are not dinosaurs!: The allegation that birds evolved from dinosaurs is frequently treated as factual by evolutionists. Now, researchers have refuted that notion—and it starts with an unexpected discovery about bird anatomy. Read more.


Birds are dinosaurs?: Creationists don’t claim that dinosaurs are still alive today. But because we believe at least two of each dinosaur kind survived Noah’s Flood (i.e., were on the Ark), we view the possibility as distinctly more likely than evolutionists. Read more.
