متن کاملLessons from the first dorsal fin in atheriniforms—A new mode of dorsal fin development and its phylogenetic implications
The median fins in extant actinopterygians are the product of millions of years of evolution. During this time, different developmental patterns for the dorsal and anal fins emerged leading to a high variation in median fin morphology and ontogeny. In this study, the development of anal and dorsal fins in atheriniforms is described and its consequences for the current phylogenetic hypothesis ar...
