Anal fins hold key to evolutionary history” from Planet Earth Online

A new study shows that Euphanerops, a 400 million year old jawless fish had a pair of fins located behind its anus. This is a unique characteristic, as most fish have a single anal fin, two pectoral fins and two pelvic fins. As far as we know, this is the only fish with this characteristic. These findings will help scientists better reconstruct the evolutionary history of jawed vertebrates, our ancestors.
