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. The pig-like creatures are made up of two families:
Six bovid species (clockwise from top left): addax, cattle, mountain gazelle, impala, blue wildebeest, and mouflon Bovidae is a family of hoofed ruminant mammals in the order Artiodactyla . A member of this family is called a bovid.
Nevertheless, many perissodactyl species survived and prospered until the late Pleistocene (about 10,000 years ago) when they faced the pressure of human hunting and habitat change. Artiodactyl evolution
The collared peccary (Dicotyles tajacu) is a peccary, a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America.It is the only member of the genus Dicotyles.
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.
Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.

Hippopotamidae is a family of stout, naked-skinned, and semiaquatic artiodactyl mammals, possessing three-chambered stomachs and walking on four toes on each foot. While they resemble pigs physiologically, their closest living relatives are the cetaceans.
