Present-day Slovenia has been inhabited since prehistoric times. There is evidence of human habitation from around 250,000 years ago. A pierced cave bear bone, dating from 43100 ± 700 BP, found in 1995 in Divje Babe cave near Cerkno, is considered a kind of flute, and possibly the oldest musical instrument discovered in the world. In the 1920s and 1930s, artifacts belonging to the Cro-Magnon, such as pierced bones, bone points, and a needle were found by archaeologist Srečko Brodar in Potok Cave.
