With the exception of the canines in males, the teeth stop growing during the middle of the fourth year. Ruvinsky, A. et al. Additionally, the Wild boar has been known to hunt on livestock such as small calves or lambs. Because their short legs, these animals move through snow with great difficulty. 153–155. Subadult males may live in loosely knit groups, while adult and elderly males tend to be solitary outside the breeding season. While domestic pigs, both captive and feral (popularly termed "razorbacks"), have been in North America since the earliest days of European colonization, pure wild boars were not introduced into the New World until the 19th century. The diet of these mammals is generally composed of plants such as crops, fruits, nuts (mast), roots and green plants, supplemented with bird eggs, carrion, small rodents, insects and worms. In modern times, tiger numbers are too low to have a limiting effect on boar populations. These resting places are occupied by whole families (though males lie separately) and are often located in the vicinity of streams, in swamp forests and in tall grass or shrub thickets. The neonatal coat fades after three months, with adult colouration being attained at eight months. , Boar attacks on humans have been documented since the Stone Age, with one of the oldest depictions being a cave painting in Bhimbetaka, India.  By the late Villafranchian, S. scrofa largely displaced the related S. strozzii, a large, possibly swamp-adapted suid ancestral to the modern S. verrucosus throughout the Eurasian mainland, restricting it to insular Asia. , The wild boar inhabits a diverse array of habitats from boreal taigas to deserts. , Roman relief of a dog confronting a boar, Cologne, Southern Indian depiction of boar hunt, c. 1540, The Boar Hunt – Hans Wertinger, c. 1530, the Danube Valley, Boars can be damaging to agriculture in situations where their natural habitat is sparse. Independence is reached within 7 months. According to Tacitus, the Baltic Aesti featured boars on their helmets and may have also worn boar masks (see for example the Guilden Morden boar). Male Wild boars tend to lead solitary life during the most of the year. The hare, a favoured game animal, is ubiquitous.  Boars in captivity have lived for 20 years. Boars are regularly encountered in pistachio groves in winter in some areas of Tajikistan and Turkmenistan, while in spring they migrate to open deserts; boar have also colonized deserts in several areas they have been introduced to. Iolo Williams, the BBC Wales wildlife expert, attempted to film Welsh boar in late 2012. By 1950, wild boar had once again reached their original northern boundary in many parts of their Asiatic range. Wild boars were apparently already becoming rare by the 11th century since a 1087 forestry law enacted by William the Conqueror punishes through blinding the unlawful killing of a boar. As in natural conditions, sounders in peri-urban areas are matriarchal, though males tend to be much less represented and adults of both sexes can be up to 35% heavier than their forest-dwelling counterparts. But according to a zoo-archaeological evidence, namely, bones and teeth, domestication of these mammals began about 9,000 - 10,000 years ago, on the territory of modern Eastern Turkey. There are significant variations within this subspecies and it is possible there are actually several subspecies involved. , On the islands of Komodo and Rinca, the boar mostly inhabits savanna or open monsoon forests, avoiding heavily forested areas unless pursued by humans.  In the Amur region, wild boars are one of the two most important prey species for tigers alongside the Manchurian wapiti, with the two species collectively comprising roughly 80% of the felid's prey.  The piglets do not leave the lair for their first week of life. The lower canines are much sharper and longer, with the exposed parts measuring 10–12 cm (3.9–4.7 in) in length. As true wild boars became extinct in Great Britain before the development of Modern English, the same terms are often used for both true wild boar and pigs, especially large or semi-wild ones. Wild boar live in a wide range of habitats, all of which usually include a water source and thick brush for protection from predators. They generally occur during the boars' rutting season from November to January, in agricultural areas bordering forests or on paths leading through forests. Descendants of the Powder Horn Ranch boars were later released onto San José Island and the coast of Chalmette, Louisiana. "Systematics and evolution of the pig". , Sexual dimorphism is very pronounced in the species, with males being typically 5–10% larger and 20–30% heavier than females. At this point, the male fiercely fights potential rivals.  Virtually all heroes in Greek mythology fight or kill a boar at one point. Wild boar also carry parasites known to infect humans, including Gastrodiscoides, Trichinella spiralis, Taenia solium, Balantidium coli and Toxoplasma gondii. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. In: Ruvinsky A, Rothschild MF (eds), Groves, C. P. et al. , In recent centuries, the range of wild boar has changed dramatically, largely due to hunting by humans and more recently because of captive wild boar escaping into the wild.  Nevertheless, the importance of the boar as a culinary item among Celtic tribes may have been exaggerated in popular culture by the Asterix series, as wild boar bones are rare among Celtic archaeological sites and the few that do occur show no signs of butchery, having probably been used in sacrificial rituals. In the Białowieża Forest, the animal's primary habitat consists of well-developed broad-leaved and mixed forests, along with marshy mixed forests, with coniferous forests and undergrowths being of secondary importance. , Wild boars are an invasive species in the Americas and cause problems including out-competing native species for food, destroying the nests of ground-nesting species, killing fawns and young domestic livestock, destroying agricultural crops, eating tree seeds and seedlings, destroying native vegetation and wetlands through wallowing, damaging water quality, coming into violent conflict with humans and pets and carrying pig and human diseases including brucellosis, trichinosis and pseudorabies. For first-time breeders, it lasts 114–130 days, while it lasts 133–140 days in older sows. The species occasionally, but rarely contracts Pasteurellosis, hemorrhagic sepsis, tularemia, and anthrax. On Sakhalin, there are only fossil reports of wild boar.  This dependence on wild boar is largely due in part to the local leopard subspecies' large size. The animal's link to prosperity was illustrated by its inclusion on the ¥10 note during the Meiji period and it was once believed that a man could become wealthy by keeping a clump of boar hair in his wallet.  Archaeological evidence suggests that pigs were domesticated from wild boar as early as 13,000–12,700 BCE in the Near East in the Tigris Basin, being managed in the wild in a way similar to the way they are managed by some modern New Guineans.  Boars inhabiting the Volga Delta and near some lakes and rivers of Kazakhstan have been recorded to feed extensively on fish like carp and Caspian roach. From earliest times, because of its great strength, speed, and ferocity, the wild boar has been one of the favourite beasts of the chase. The animal typically attacks by charging and pointing its tusks towards the intended victim, with most injuries occurring on the thigh region. They are also threatened from large-scale hunting for consumption, sport and as pests (especially near human settlements). Wolves primarily target piglets and subadults and only rarely attack adult sows. The function of this sack is not fully understood.  The white boar served as the badge of King Richard III of England, who distributed it among his northern retainers during his tenure as Duke of Gloucester.  Apicius devotes a whole chapter to the cooking of boar meat, providing 10 recipes involving roasting, boiling and what sauces to use. Overall, Wild boars live in areas with a constant source of water and dense vegetative cover to serve them as refuge from predators.  In Denmark, the last boar was shot at the beginning of the 19th century, and by 1900 they were absent in Tunisia and Sudan and large areas of Germany, Austria and Italy. It was once found in North Africa along the Nile valley up to Khartum and north of the Sahara. Farrowing occurs between March and May, with litter sizes depending on the age and nutrition of the mother. The demigod Herakles' third labour involves the capture of the Erymanthian Boar, Theseus slays the wild sow Phaea, and a disguised Odysseus is recognised by his handmaiden Eurycleia by the scars inflicted on him by a boar during a hunt in his youth. The term wild boar, or wild pig, is sometimes used to refer to any wild member of the Sus genus. Although the bear and wolf are now extinct…, …warthog, five in the European wild pig, and two in peccaries.…. This association likely arose from aspects of the boar's actual nature.  Wild boar are known to be competent swimmers, capable of covering long distances. The wild boar inhabits a diverse array of habitats from boreal taigas to deserts. [a], The breeding period in most areas lasts from November to January, though most mating only lasts a month and a half. Several specimens escaped six years later, dispersing into the William C. Whitney Wilderness Area, with their descendants surviving for at least 20 years. A story present in the Brahmanas has the god Indra slaying an avaricious boar, who has stolen the treasure of the asuras, then giving its carcass to the god Vishnu, who offered it as a sacrifice to the gods.  The animal can run at a maximum speed of 40 km/h (25 mph) and jump at a height of 140–150 cm (55–59 in).  Domestic pigs tend to have much more developed hindquarters than their wild boar ancestors, to the point where 70% of their body weight is concentrated in the posterior, which is the opposite of wild boar, where most of the muscles are concentrated on the head and shoulders. , Wild boar of unknown origin were stocked in a ranch in the Edwards Plateau in the 1940s, only to escape during a storm and hybridize with local feral pig populations, later spreading into neighboring counties. Boar hunting continued after the fall of the Western Roman Empire, though the Germanic tribes considered the red deer to be a more noble and worthy quarry. (2011). Although the lactation period lasts 2.5–3.5 months, the piglets begin displaying adult feeding behaviours at the age of 2–3 weeks. From here, the boundary went slightly north of the Amur River eastward to its lower reaches at the Sea of Okhotsk. These back bristles form the aforementioned mane prominent in males and stand erect when the animal is agitated. As an article of food, the boar’s head was long considered a special delicacy. According to IUCN, the wild boar is abundant and widespread throughout its range but no overall population estimate is available. In many parts of their range, these mammals heavily suffer from destruction of their natural habitat. It has been introduced to New Zealand and to the United States (where it mixed with native feral species). However, various localized concerns negatively affect populations of this species. These escapees have ranged widely, with some specimens having been observed crossing into Vermont. These represent four separate, independent mutations. In the Belovezh forest for example, 34–47% of the local boar population will enter fields in years of moderate availability of natural foods.
