Hogs - or pigs - are the often underestimated and humble livestock that have likely been domesticated for thousands of years. A global source of meat believed to be descended from the wild boars of Eurasia; pigs are unique in that they are likely livestock for settled farming communities rather than nomadic peoples since they are not easily herded for long distances. Pig, swine, shoat, piglet, boar, hog, stag, gilt, sow, or barrow; no matter how you describe them, these animals are an integral part of food and economics for many countries across the globe.
