According to this diagram, is the pig more closely related to the dog or kangaroo?

Answer explanation

Dogs are closer to pigs on this diagram because they share a more recent common ancestor with pigs. Fun fact: pigs and dogs are mammals. Kangaroos are marsupials; they carry their young in a pouch.
