A simplified family tree of placental mammals based on molecular evidence. In each group one typical animal is illustrated. Anteaters and pangolins form a group on their own, with all the other mammals grouped in the Epitheria. There are four branches: carnivores and insectivores, primates, squirrels and ungulates. The ungulates are sub-divided into 6 groups: camels, whales, rhinos, hyrax, manatees and elephants.
