Dinosaur
Although we never designed them other than flying above our heads, birds have a very different origin. They are dinosaurs. More precisely theropods, a clade comprising almost all of the large carnivorous dinosaurs.
It was in 1973 (as much to say yesterday) that John Ostrom published for the first time some details of his hypothesis, according to which the problem of the origin of birds was a solvable question and that they had evolved from small carnivorous dinosaurs. .
Ostrom had based his hypothesis on anatomical comparisons of all parts of the skeleton.
Today most scientists agree with this hypothesis.
