A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar (Sus scrofa), along with other species; related creatures outside the genus include the peccary, the babirusa, and the warthog. Pigs, like all suids, are native to the Eurasian and African continents. Juvenile pigs are known as piglets. Pigs are highly social and intelligent animals.
With around 1 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet. Pigs are omnivores and can consume a wide range of food, similar to humans. Pigs can harbour a range of parasites and diseases that can be transmitted to humans. Because of the similarities between pigs and humans, pigs are used for human medical research.
