Abstract
Living gnathostomes (jawed vertebrates) share numerous derived morphologies including stable fin patterns, cranial organisation, axial regionalisation, internal gill skeletons, jaws and teeth. Many aspects of these characteristics now appear to be governed by conserved developmental - regulatory systems. The gnathostome evolutionary radiation therefore probably coincided with a major phase of elaborative developmental reorganisation. Phylogenetic analysis of early gnathostomes, using new data from recently discovered, remarkably well preserved primitive chondrichthyans therefore provides an opportunity to test existing hypotheses and generate new hypotheses of vertebrate developmental evolutionary change.
