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] UBERON:0001710 VHOG:0000453 lower part of mouth mandibular part of mouth mandibular series ncithesaurus:Lower_Jaw uberon skeleton of lower jaw endoderm-derived structure mandibular prominence structure with developmental contribution from neural crest
