The cardiac neural crest cells (CNCCs) have played an important role in the evolution and development of the vertebrate cardiovascular system: from reinforcement of the developing aortic arch arteries early in vertebrate evolution, to later orchestration of aortic arch artery remodeling into the great arteries of the heart, and finally outflow

First, the retention of “aortic arch arteries” (or “branchial arch arteries”) in non-aquatic vertebrates serves no respiratory function. They are merely connecting pipes. Their sole purpose is to be used as building blocks to construct modified circulatory elements which function in the species which possess them. But remember, in principle, such “building blocks” might have been

Other arches have been lost and modified through evolution to result in the joining of the ventral and dorsal aorta by the fourth aortic arch, which is now known as the arch of aorta (Holmes, 1975). The lungs of amphibians cannot be relied on for all of their air supply, and other pathways are therefore necessary (Holmes, 1975 ).
