Uberon Homology note : (...) mouth development is very similar in protostomes and 'basal' deuterostomes,
whereas the chordate mouth seems to develop at a new position. Recent data for echinoderms
and hemichordates further suggest that this change in mouth position may result from
change in the influence of a conserved ectodermal patterning system on mouth development.
It has been suggested that the mouths of vertebrates and urochordates may constitute
a 'new' mouth.[well established][VHOG];
