Archaeological research, dating from 2013, suggests that pigs were originally domesticated in Central Asia. Domestic pigs are descended from a Euro-Asian species of wild boar and have hybridized with wild subtypes of this species throughout its range.
This hybridizing has resulted in European domestic pigs having similar genes as European wild pigs, muddying the issue of their origins. However, DNA studies of the earliest domesticated pig remains in Europe show that these pigs actually have genes more similar to Near Eastern wild pigs than to their European wild neighbors. This means that the genes of the European subspecies had to have been introduced later, rather than being part of the original gene pool that ancient farmers drew upon.
