Domestic Pig

• Its gestation lasts, by the stockman's classic rule, three months, three weeks and three days: about 114 days.
• It has hardly any functional sweat glands, which is why it wallows in mud to cool down and to protect itself from the sun and from parasites.
• It was domesticated at least twice, separately, from the wild boar, Sus scrofa: once in Anatolia and once in China, some 9,000 years ago.
• Today's European pigs are a striking case of genetic replacement: the first ones arrived from the Near East with the Neolithic farmers, but they then interbred so much with European wild boar that their original genetic signature almost disappeared.
• Its gestation follows the stockman's classic rule: three months, three weeks and three days — about 114 days.
• It is a true omnivore, not an adapted herbivore, and that dietary flexibility is what made it compatible with human settlements from the very beginning.
• It has an exceptional sense of smell, which is put to use finding truffles.
