homology_notes
Experients in amphibia have shown that an intrinsic feature of the pharyngeal endoderm is its ability to generate taste buds and this capacity must have been acquired by the endoderm at the origin of the vertebrates.[well established][VHOG]

In humans, saste buds may be found on the tongue, soft palatte, epiglottis and upper pharynx. In other species they may be found in more unusual places, such as the trunk, or on the barbels or fins of fish.
