A vulture-bone flute discovered in a European cave is likely the world's oldest recognizable musical instrument and pushes back humanity's musical roots, a new study says.

Found with fragments of mammoth-ivory flutes, the 40,000-year-old artifact also adds to evidence that music may have given the first European modern humans a strategic advantage over Neanderthals, researchers say.

The bone-flute pieces were found in 2008 at Hohle Fels, a Stone Age cave in southern Germany, according to the study, led by archaeologist Nicholas Conard of the University of Tübingen in Germany.

With five finger holes and a V-shaped mouthpiece, the almost complete bird-bone flute—made from the naturally hollow wing bone of a griffon vulture—is just 0.3 inch (8 millimeters) wide and was originally about 13 inches (34 centimeters) long.

Flute fragments found earlier at the nearby site of Geissenklösterle have been dated to around 35,000 years ago.

The newfound flutes, though, "date to the very period of settlement in the region by modern humans ... about 40,000 years ago," Conard said.

The mammoth-ivory flutes would have been especially challenging to make, the team said.

Using only stone tools, the flute maker would have had to split a section of curved ivory along its natural grain. The two halves would then have been hollowed out, carved, and fitted together with an airtight seal.

Music as a Weapon?

Music may have been one of the cultural accomplishments that gave the first European modern-human (Homo sapiens) settlers an advantage over their now extinct Neanderthal-human (Homo neanderthalis) cousins, according to the team.
