Genomic Study Rewrites Shark Evolutionary Tree

No such thing as a shark? Genomes shake up ocean predator’s family tree

Sharks might not be a natural biological group, with most species potentially closer kin to rays than to an oddball group of sharks. Sharks might not be a natural biological group, with most species potentially closer kin to rays than to an oddball group of sharks.

The concept of sharks as a natural biological group has been challenged by recent findings in genomic studies. The study, published last month on the bioRxiv preprint server, suggests that sharks might not be a single evolutionary lineage after all. Instead, some species of sharks may be more closely related to rays and skates than to other sharks.
