The Most Beautiful Rare Birds In The World
Birds, unlike other living worlds have some features. They are the first constant temperature organisms. Notably, all of its members are covered with feathers that are not seen in any other animal group. The anterior members are turned into wings and the bones in the posterior members are lined up to form the intertarsal joint. There are highly developed sound boxes where the trachea and bronchi are located.
There is much evidence to suggest that birds evolved with the evolution of dinosaurs; these are the air gaps in the bones, the similarities in the chest, wing-anterior extremity structures, the wishbone that is found only in birds today, and in the dinosaur skeletal structures. Furthermore, with the development of genetic science, scientists working on bird embryos have opened some closed genes and have obtained similar images (tooth, scales, neck and tail structure) in bird embryos similar to those of dinosaur embryos, the evolutionary ancestor of birds.
