You’re looking at the oldest sewing needle in the world, found last summer in a Siberian cave. It’s estimated to be 50,000 years old and made by our Denisovan ancestors, a recently-discovered hominin species or subspecies named after the cave in which evidence of their existence was found. The needle is made from the bone of a to-be-identified large bird and appears to still be perfectly usable after all this time.
