Some roughly 8,000-year-old pig teeth now offer evidence that the mammals were first domesticated from wild boar in South China. For years, archaeologists and anthropologists have considered present-day China as the likely location for pig domestication. Compared to domestic pigs, wild boars have larger heads and mouths, and bigger teeth. The brownish yellow, football-shaped parasite eggs were found in 16 of the pig teeth. “Our study shows that some wild boars took the first step towards domestication by scavenging human waste,” said Wang.
