We study the skeletal and nervous development of fish in order to identify their modules (network of elements that act like relatively independent units) and patterning (order of formation of this elements) in order to solve the phylogeny of gnathostomes. We will a test our theoretical model of modularity in lampreys, chondrichthyes as well as bony fishes.
