history of pigs

For decades, scholars researched and debated whether Mesolithic hunters in Europe had developed domestic pigs prior to the LBK migration. [17] Domestic pigs are raised commercially as livestock; materials that are garnered include their meat (known as pork), leather, and their bristly hairs which are used to make brushes. Its many subspecies are native to all but the harshest climates of continental Eurasia and its islands and Africa as well, from Ireland and India to Japan and north to Siberia. In southwest Asia, pigs were part of a suite of plants and animals that were developed in the upper reaches of the Euphrates river about 10,000 years ago. Pigs are particularly valued in China and on certain oceanic islands, where their self-sufficiency allows them to be turned loose, although the practice is not without its drawbacks (see environmental impact). Moreover, it may be possible to investigate the early history of the domestic pig by analyzing mtDNA from the rich collections of pig bones from Neolithic to medieval times. [14] Older pigs will consume three to five gallons of water per day. Those advancements have made the U.S. the world’s leader in pork production. The suids are a sister clade to peccaries. [42], Some strains of influenza are endemic in pigs. ... Another Old English word for "pig" was fearh, related to furh "furrow," from PIE *perk- "dig, furrow" (source also of Latin porc-us "pig," see pork). Beginning about 7,000 years ago, central Asian people moved into Europe, bringing their suite of domestic animals and plants with them, following at least two main paths. After that initial domestication, pigs accompanied early farmers as they spread out of Anatolia to Europe, and out of central China to the hinterlands. In the male, the canine teeth form tusks, which grow continuously and are sharpened by constantly being ground against each other. [3][4] Pigs are omnivores and can consume a wide range of food. The pygmy hog, formerly Sus salvanius is now placed in the monotypic genus Porcula. Since then, diversified family farms have been the home of the vast majority of the pigs raised in the U.S. The Domestication of Pigs: Sus Scrofa's Two Distinct Histories. Early Neolithic pig domestication at Jiahu, Henan Province, China: clues from molar shape analyses using geometric morphometric approaches. Others may cause the death of the piglets and sometimes, the mother may eat the piglets. To stop this, farmers erected a wall along the island, and the avenue along that wall later became known as Wall Street! Overall body size (in particular, measures of knucklebones [astralagi], front leg bones [humeri] and shoulder bones [scapulae]) has been commonly used to differentiate between domestic and wild pigs since the mid-twentieth century. [23], Pigs have been domesticated since ancient times in the Old World. Pigs are enormously important to U.S. agriculture, the general economy, the livelihoods of thousands of family farmers, and the diet of millions of Americans. [32], Pigs have been important in culture across the world since neolithic times. Some countries have recognized the issue and are beginning to support the continued maintenance of the non-commercial breeds as a genetic resource for the future. The ancestor of the domestic pig is the wild boar, which is one of the most numerous and widespread large mammals. The early enclosures used by Chinese farmers made the process of pig domestication much faster in China compared to the process used on western Asian pigs, which were allowed to roam freely in European forests up through the late Middle Ages. The late adoption of cattle and pig husbandry in Neolithic Central Turkey. A pig is any of the animals in the genus Sus, within the even-toed ungulate family Suidae. They uproot large areas of land, eliminating native vegetation and spreading weeds. Pigs also can acquire human influenza. [6], The Online Etymology Dictionary provides anecdotal evidence as well as linguistic, saying that the term derives, probably from Old English *picg, found in compounds, ultimate origin unknown. The study concluded that human selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars and created domestication islands in the genome. [38][39][40][37], Domestic pigs that have escaped from urban areas or were allowed to forage in the wild, and in some cases wild boars which were introduced as prey for hunting, have given rise to large populations of feral pigs in North and South America, Australia, New Zealand, Hawaii, and other areas where pigs are not native. Both wild and feral pigs are commonly hunted. [35][36] [10] Some attacks on newborn piglets are non-fatal. The pig has been celebrated throughout Europe since ancient times in its carnivals, the name coming from the Italian carne levare, the lifting of meat. Pigs were brought to southeastern North America from Europe by Hernando de Soto and other early Spanish explorers. The rear teeth are adapted for crushing. The domestic pig (Sus scrofa domesticus) is usually given the scientific name Sus scrofa, although some taxonomists call it S. domesticus, reserving S. scrofa for the wild boar. [15] When kept as pets, the optimal healthy diet consists mainly of a balanced diet of raw vegetables, although some may give their pigs conventional mini pig pellet feed.[16]. It is said Christopher Columbus had eight pigs in tow when traveling to Cuba in 1493 after his initial voyage to the “New World.” But his successor in exploring the Americas, Hernando de Soto, is said to have brought 13 pigs with him when first landing in what’s today Tampa Bay, Florida, making that “baker’s dozen” the first domesticated pigs to set foot in what would become the United States of America. [9], The dental formula of adult pigs is, giving a total of 44 teeth.

Apparently related to Low German bigge, Dutch big ("but the phonology is difficult" -- OED). Cucchi and colleagues (2016) suggest this may have been the result of a social-political change during the Longshan, although they recommended additional studies. Accidental or deliberate releases of pigs into countries or environments where they are an alien species have caused extensive environmental change. This may also shed light on the early migration of agricultural tribes in Eurasia. Are Female Astronauts the Future of Space. If there is increased foraging of wild boars in certain areas, they can cause a nutritional shortage which can cause the pig population to decrease. The domestication history of pigs (Sus scrofa) is a bit of an archaeological puzzle, in part because of the nature of the wild boar that our modern pigs are descended from. Their head and body length ranges from 0.9 to 1.8 m (35 to 71 in) and they can weigh between 50 and 350 kg (110 and 770 lb). A number of extinct species (†) are known from fossils.
