Is the Ostrich REALLY like the PAST?Ostrich are birds, you say, Well, maybe not! Recent evidence indicates that ostrich, and other members of the ratite family, have a lot more in common with dinosaurs that was previously thought. This evidence blended with the fact that the ratite family has very little in common with other bird species, has caused the scientific community to question whether ostrich are really birds after all!
Perhaps the Chinese know this, long before our modern scientists, for their belief in the mystical, long necked, partially-feathered "dragon" is linked to the ancient medicinal use of fossilized dinosaur bones. It could be that the similarities between the mythical dragon and ostrich are no coincidental because evidence suggests that ostrich lived naturally in China, into time recent enough for their having been hunted and eaten by ancient peoples.
What evidence suggests that ostrich might be misclassified as birds? Ostrich have no keel (the bony plate that protrudes from the sternum of all other birds). It is to this bone that the powerful muscles of flight are attached (creating the breast meat we know in chicken, turkeys, ducks and geese).
It was previously thought that the ostrich "lost" their keel as they evolved, but now there is doubt they ever had one. the ratite sternum is a structure non adaptable for flight, and is of the same sort found in dinosaurs.
Ratite DNA, or genetic material, reveals distant relatedness, at best to other birds.
Ratite sperm differs fundamentally from that of all other birds.
Ostrich skulls are not fused. The skulls of birds are fused into a solid, single structure, that can help protect the brain from mechanical stresses like those during flight, whereas ostrich skulls are dinosaur like, made up of several jointed bony plates.
The upper jaw bones of the ratite are not the same as those in a typical bird. The structural organization of the ratite jaw resembles a condition well-developed in dinosaurs, one that helped move the upper jaw to enlarge gape or mouth opening.
