Pigs were most likely brought to Israel about 3,000 years ago by non-kosher Philistines, according to research published this week in Scientific Reports. DNA testing of ancient and modern pigs indicates that emigrant pigs from Europe started showing up around 900 B.C., eventually overtaking the wild boar population in what is now Israel, researchers said. The presence of European pigs in the region is key to understanding how humans and animals migrated, said Tel Aviv University's Israel Finkelstein. "We archaeologists know that pigs and pork consumption are two very good markers of ethnicity and identity," Finkelstein said.
