Question

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?

Answer 1

Pharyngeal nerves in vertebrates are longer than the direct distance from the central nervous system to the target due to neural evolution.

Step-by-step explanation:

Pharyngeal nerves in vertebrates are longer than the direct distance from the central nervous system to the target because they evolved from preexisting structures. This phenomenon can be best explained by the concept of neural evolution. Neural evolution refers to the process of gradual changes in the structure and function of the nervous system over time. In the case of pharyngeal nerves, they have become longer due to the evolution of complex structures and functions that required extended connections between the central nervous system and the target organs.

Answer 2

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.
