Abstract: | Bony fishes (Osteichthyes) comprise over 22,000 species, about half of all vertebrate species. In order to investigate the phylogenetic relationships within this vertebrate class, we have studied the only protein whose primary structure is known in a rather large (27) number of fish species belonging to seven orders—the growth hormone. The phylogeny obtained using the maximum parsimony method based on amino acid sequences represents the first molecular phylogeny of teleostean fishes based on an extensive set of data. This phylogeny agrees remarkably well with the generally accepted phylogeny based on morphological characters and paleontological data.
