Scientist says ostrich study confirms bird 'hands' unlike those of dinosaurs

lantation and replacement.

Findings from careful examinations of alligator and turtle embryos were consistent with those of birds, the scientist added.

Far more likely is that birds and dinosaurs had a much older common ancestor, he said. Many superficial similarities between birds and dinosaurs arose because both groups developed body designs for walking upright on two hind legs and began to resemble each other over millions of years. "It is now clear that the origin of birds is a much more complicated question than has been previously thought," Feduccia said.
