The segmental patterning of the vertebrate hindbrain has been intensely investigated, yet the evolutionary origin of hindbrain segmentation remains unclear. In the vertebrate sister group, amphioxus (Cephalochordata), the embryonic neural tube lacks obvious morphological segmentation, but comparative Hox gene expression analysis has suggested the presence of a region homologous to the vertebrate hindbrain. Does this region contain ancient segmental features shared with the vertebrate hindbrain… CONTINUE READING
