Archaeologists have announced the discovery of a 50,000-year-old sewing needle, made from bone, that was excavated from a cave in Siberia's Altai Mountains. This well-preserved sewing implement sports a hole for guiding the thread, and is still appears to be sharp enough to be used today. This artifact, however, has an unusual distinction, in that it is suspected that it was not crafted by a human hand.
