prairie dog?!??! excuse me? but kindly, who the fuck do you think you are? prairie dogs are RODENTS. the animals depicted in this video are hyraxes (the closest relatvie to the elephant mind you). Elephants are NOT rodents. neither are these beautiful hyraxes aka dassies (the closest relative to the elephant).
Elephants used to have closer relatives, but the only extant members of paenungulata are elephants, sea cows, and hyraxes. They're not close relatives, they split off some 60 million years ago, but they're still each other's closest relatives that are still around.
