>>85364322Sharks & fishes are genetically more different than mammals & fish. SHARKS ARE OLDER THAN TREE, you fucking retard.
Fish & sharks don't even share similar bone structures. Sharks' bones aren't dense like fish. >B-but gills.
Even that, we suck our own oxygen similar to fish & their gill flaps, while sharks use ram ventilation.
And fish's gills & sharks' gills are very different too.
