context_page_description: The wild boar, also known as the "wild swine", "common wild pig", or simply "wild pig", is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World.
  As of 1990, up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young. Fully grown males are usually solitary outside the breeding season. The grey wolf is the wild boar's main predator in most of its natural range except in the Far East and the Lesser Sunda Islands, where it is replaced by the tiger and Komodo dragon respectively.
context_section_description: As of 2005, 16 subspecies are recognised, which are divided into four regional groupings:
  Western: Includes S. s. scrofa, S. s. meridionalis, S. s. algira, S. s. attila, S. s. lybicus and S. s. nigripes. These subspecies are typically high-skulled (though lybicus and some scrofa are low-skulled), with thick underwool and (excepting scrofa and attila) poorly developed manes.
  Indian: Includes S. s. davidi and S. s. cristatus. These subspecies have sparse or absent underwool, with long manes and prominent bands on the snout and mouth. While S. s. cristatus is high-skulled, S. s. davidi is low-skulled.
  Eastern: Includes S. s. sibiricus, S. s. ussuricus, S. s. leucomystax, S. s. riukiuanus, S. s. taivanus and S. s. moupinensis. These subspecies are characterised by a whitish streak extending from the corners of the mouth to the lower jaw. With the exception of S. s. ussuricus, most are high-skulled. The underwool is thick, except in S. s. moupinensis, and the mane is largely absent.
  Indonesian: Represented solely by S. s. vittatus, it is characterised by its sparse body hair, lack of underwool, fairly long mane, a broad reddish band extending from the muzzle to the sides of the neck. It is the most basal of the four groups, having the smallest relative brain size, more primitive dentition and unspecialised cranial structure.
