Roughly 7,000-year-old cords found in a stunning Spanish cave are Europe's oldest bowstrings made of sinew, new research finds.
The bowstrings — along with fragments of wood-and-reed arrows, one with two features still affixed — date to the early Neolithic, when ancient Europeans first began farming. They're at least 2,000 years older than the next-oldest known bowstrings made from animal products in Europe, which were found near the famous ice mummy Ötzi in the Italian Alps.
