2. Classification With around 2 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet. The ancestor of the domesticated pig is the wild boar, which is one of the most numerous and widespread large mammals. Its many subspecies are native to all but the harshest climes of continental Eurasia and its islands, from Ireland and India to Japan and north to Siberia. Although it has been exterminated in some areas, its numbers are stable or even increasing rapidly, in most of its native range. Long isolated from other pigs on the many islands of Indonesia, Malaysia, and the Philippines, pigs have evolved into many different species, including wild boar, bearded pigs, and warty pigs. Humans have introduced pigs into Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which have gone feral, or as wild boar. These have typically adapted well, and are increasing in number and broadening their range outside human control Pigs are omnivores, which means that they consume both plants and animals. In the wild, they are foraging animals, primarily eating leaves, grasses, roots, fruits and flowers. In confinement pigs are fed mostly corn and soybean meal with a mixture of vitamins and minerals added to the diet A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, ancestor to the wild boar, and several other wild relatives. Pigs are omnivores and are highly social intelligent animals http://en.wikipedia.org/wiki/Pig
