Whatever the common ancestor of the lamprey and gnathostomes may have looked like, it most likely possessed a neural-crest-derived premandibular ectomesenchyme closely associated with the NHP. Invention of the jaw subsequently required a space for the nasal septum and maxillary process to develop, which might have been provided by subdivision of the NHP into the nasal placode and the hypophysis (diplorhiny, the state of bilaterally separated nasal openings, would also have been a prerequisite for this).[well established][VHOG] |
