Thousands of Lower Paleolithic artefacts have been recovered from Monte Poggiolo, dating as far back as 850,000 years. Excavations throughout Italy revealed a Neanderthal presence dating back to the Middle Palaeolithic period some 200,000 years ago, while modern humans appeared about 40,000 years ago at Riparo Mochi. Archaeological sites from this period include Addaura cave, Altamura, Ceprano, and Gravina in Puglia. The Ancient peoples of pre-Roman Italy – such as the Umbrians, the Latins (from which the Romans emerged), Volsci, Oscans, Samnites, Sabines, the Celts, the Ligures, the Veneti, the Iapygians, and many others – were Indo-European peoples, most of them specifically of the Italic group.
