The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
It is a species-poor artiodactyl suborder of North American origin [27] that is well adapted to extreme habitats—the dromedary and Bactrian camels in the Old World deserts and the guanacos, llamas, vicuñas, and alpacas in South American high mountain regions.
Perissodactyls were the dominant group of large terrestrial browsers right through the Oligocene. However, the rise of grasses in the Miocene (about 20 Mya) saw a major change: the artiodactyl species with their more complex stomachs were better able to adapt to a coarse, low-nutrition diet, and soon rose to prominence.

Entelodontidae is an extinct family of pig-like artiodactyls (even-toed ungulates) which inhabited the Northern Hemisphere (Asia, Europe, and North America) from the late Eocene [1] to the early Miocene epochs, about 38-19 million years ago.
The Asian species weigh between 1–4 kg (2–9 lb), while the African chevrotain is considerably larger, at 7–16 kg (15–35 lb). [ 8 ] [ 9 ] With an average length of 45 cm (18 in) and an average height of 30 cm (12 in), the Java mouse-deer is the smallest surviving ungulate (hoofed) mammal, as well as the smallest artiodactyl (even-toed ...
The two species were formerly considered conspecific under the scientific name Phacochoerus aethiopicus, but today this is limited to the desert warthog, while the best-known and most widespread species, the common warthog (or simply warthog), is Phacochoerus africanus.
