Gegenbaur's classical hypothesis of jaw-gill arch serial homology is widely cited, but remains unsupported by either palaeontological evidence (for example, a series of fossils reflecting the stepwise transformation of a gill arch into a jaw) or developmental genetic data (for example, shared molecular mechanisms underlying segment identity in the mandibular, hyoid and gill arch endoskeletons). Here we show that nested expression of Dlx genes--the 'Dlx code' that specifies upper and lower jaw… CONTINUE READING

Here we show that nested expression of Dlx genes -- the ' Dlx code ' that specifies upper and lower jaw identity in mammals and teleosts -- is a primitive feature of the mandibular , hyoid and gill arches of jawed vertebrates .
