	The '''] ]''' (''Sus scrofa domestica'') is usually given the scientific name ''Sus scrofa'', though some authors call it ''S. domestica'', reserving ''S. scrofa'' for the ]. It was ] approximately 5,000 to 7,000 years ago. Pigs are found across ], the ] and extend into ] as far as ] and ]. The distinction between wild and domestic animals is slight, and domestic pigs have become ] in many parts of the world (for example, ]) and caused substantial environmental damage.

	''Sus scrofa'' has four subspecies, each occupying distinct geographical areas:
	*''Sus scrofa scrofa'' (western ], Europe)
	*''Sus scrofa ussuricus'' (northern Asia and ])
	*''Sus scrofa cristatus'' (], ])
	*''Sus scrofa vittatus'' (Indonesia)

	Pigs are one of the oldest forms of ], having been domesticated as early as ] . It is believed to have been domesticated either in the ] or in ] from the ]. The adaptable nature and ] diet of the Wild Boar allowed early humans to domesticate it much earlier than many other forms of livestock, such as ]. ] were mostly used for food, but people also used their hide for shields, their bones for tools and weapons, and their bristles for brushes. Pigs were brought to southeastern ] from ] by ] and other early ] ]s. Escaped pigs became ] and were freely used by ] as food.

	The domestic pig is farmed for its meat called ]. Products made of pork include ], ] and ]. The head of a pig can be used to make ]. ], ], and other ] from pigs are also widely used for food.

	In some ]s, such as ] and ], there are ].

	In ] nations, domestic pigs farming has shifted away from the ] to large-scale ] where meat can be mass-produced. This has resulted in lower production costs, but more significant ] concerns.

	In ]s, and some parts of ]s, the domestic pig is frequently raised outdoors in yards. In some cases pigs are even raised in open fields where they are allowed to ]; they are watched by ]s, essentially ]s for pigs.

	==As pets==
	Pigs are known to be ] animals and have been found to be more trainable than ]s or ]s. Asian ]s, a smaller ] of the domestic pig, have made popular house ]s in the ] beginning in the latter half of the ]. Regular domestic farmyard pigs have also been known to be kept indoors, but due to their large size and destructive tendencies, they typically need to be moved into an outdoor pen as they grow older. Most pigs also have an extreme fear of being picked up, but will usually calm down once placed back on the floor.
