The haunting music you hear above comes from a 43,000 year old Neanderthal bone flute. That’s right, I said ‘bone’ flute. It is believed that this instrument was made from the bone of a bear. Is that metal or what? The flute itself was found in a cave in Western Slovenia in 1995. There was a great debate over whether the holes in the bone were intentionally made or not. In 2009 this was finally resolved. A clay replica of the artifact was made, and it was verified that it indeed was made for a singular purpose – for Neanderthals to rock out with cave bears as if they were in some kind of early Led Zeppelin tribute band.
