Wild pigs or their domestic and feral derivatives have been widely distributed by man as a source of food, and naturalized populations have become established, often in large numbers, on all continents except Antarctica and on a great many oceanic islands. The overwhelming majority of naturalized populations are regional variants or derivatives of the Eurasian wild pig, Sus scrofa, although the Sulawesi warty pig, S. celebensis, has also been domesticated and introduced in some areas. The resulting diversity of native, naturalized, domestic and hybrid forms has produced patterns of distribution and interrelationships of great taxonomic confusion, particularly in the Indonesian and Papuan Archipelagos. The origins of some of these populations are obscure, though many are associated with the earliest phases of human expansion, exploration and colonization. Some are certainly thousands of years old, but the majority are much more recent and are of little immediate scientific and anthropogenic interest.
