Answer: mucilaginous sheath
Explanation:
Proteins that are functionally less important for the survival of an organism generally evolve faster than more important proteins.
Proteins serve as the building blocks for all of life's essential processes. The proteins evolve along with the genes that create them, adding new functionality or features that may potentially result in the development of new species.
The mutation of amino acid-coding nucleotides and the stabilization of novel variations in the population are the two phases required for protein evolution.
The stability of a protein's folded structure, how well it prevents aggregation, and how well it is chaperoned all affect how quickly it evolves. According to the studies, the degree of a protein's expression has a greater influence on its evolutionary rate than does the protein's functional significance.
