  • In view of the divergent anatomy of babirusas, most artiodactyl specialists agree that they represent an ancient lineage, Babyrousinae, which branched off from the rest of Suidae early in its evolution (Thenius 1970).

  • A few artiodactyl specialists make a point of using the latter name, but the former is more widely used and would easily win in a fight.

  • In more recent publications however (Groves 2001, Meijaard & Groves 2002a, b), it has been argued that most of the supposed subspecies are distinct enough to be recognised as distinct species, being as different from one another as are universally recognised species among other artiodactyl groups.

  • About 10 million years after the meteor struck, the first hoofed mammals, or ungulates, appeared. One order of ungulates, called Perissodactyla, includes just a handful of living species, such as horses,hinoceroses, and tapirs. The other order, Artiodactyla, is much larer and includes pigs, cows, goats, sheep, camels, llamas, giraffes, deer, antelopes, camels, hippopotamuses, bison, and water buffalos. Both orders of ungulates might be called tiptoers. Their hooves are actually outsized toenails, and they walk like ballerinas en pointe. . . ."Perissodactyl" means "odd-toed": the foot's axis cuts through the center of the middle digit, and the animals walk either on three toes, like rhinos and tapirs, or just one, like horses, zebras, and donkeys. "Artiodactyl" means "even-toed": the first digit (the thumb or big toe) is absent, and the feet are symmetrical, with the axis running between the third and fourth digits . . . . they appear to have a single hoof split down the center, what the King James Bible describes as the "cloven foot."
