Skates, a type of cartilaginous fish, have pectoral fins that resemble wings, allowing them to thrive in benthic ecosystems. However, the molecular basis of this unique trait remains unknown. University College London researcher Ferdinand Marlétaz aimed to investigate the evolutionary origin of these wing-like fins. Vertebrates evolved alongside key developmental innovations, including different fin structures …
