Uberon Homology note : Subsequent vertebrate evolution has also involved major alterations to the pharynx;
perhaps the most notable occurred with the evolution of the gnathostomes. This involved
substantial modifications to the most anterior pharyngeal segments, with the jaw forming
from the first, anterior, pharyngeal segment, while the second formed its supporting
apparatus, the hyoid.[well established][VHOG];
