"Suidae is a family of artiodactyl mammals which are commonly called pigs, hogs or boars. In addition to numerous fossil species, 18 extant species are currently recognized (or 19 counting domestic pigs and wild boars separately), classified into between four and eight genera. Within this family, the genus Sus includes the domestic pig, Sus scrofa domesticus or Sus domesticus, and many species of wild pig from Europe to the Pacific. Other genera include babirusas and warthogs. All suids, or swine, are native to the Old World, ranging from Asia to Europe and Africa.
The earliest fossil suids date from the Oligocene epoch in Asia, and their descendants reached Europe during the Miocene. Several fossil species are known and show adaptations to a wide range of different diets, from strict herbivory to possible carrion-eating (in Tetraconodontinae)." - (en.wikipedia.org 10.06.2020)
