 The overall impact of slavery on the Italian genetics was insignificant though, because the slaves imported in Italy were native Europeans, and very few if any of them had extra European origin.This has been further confirmed by recent biochemical analysis of 166 skeletons from three non-elite imperial-era cemeteries in the vicinity of Rome (where the bulk of the slaves lived), which shows that only 1 individual definitely came from outside of Europe (North Africa), and another 2 possibly did, but results are inconclusive.In the rest of the Italian peninsula, the amount of non European slaves was definitively much lower than that.
