Pharyngeal nerves in vertebrates are much longer than the direct distance from the central nervous system to the target, because they evolved from preexisting structures. as a result, these nerves are not as efficient as they otherwise could be. which term best explains this phenomenon?

This phenomenon is called developmental constraints where phenotype production is restraints and they tolerate change to happen in certain directions more easily than in others. Thus, provide limits on what structure animals can form. The physical parameters include cell division, growth, shape change, migration, death, and matrix secretion that are used in morphogenesis.
