Scientists say 6,200-year-old shoes found in cave challenge "simplistic assumptions" about early humans

Scientists say grass sandals discovered in a cave in Spain are 6,200 years old, making them the oldest woven grass footwear ever discovered in Europe and forcing them to rethink "simplistic assumptions" about our human ancestors in the region.

The announcement came from a team that has been studying 76 objects found many years ago in a cave in southern Spain. Researchers from the Universidad de Alcalá and the Universitat Autònoma de Barcelona said the objects were the first direct evidence of basketry among hunter-gatherer societies and early agrarian communities in southern Europe.

Among the discoveries were baskets, sandals and organic tools made of reed and esparto grass. By studying the raw materials the objects were made of, the researchers were able to date them to the early and middle Holocene period, between 9,500 and 6,200 years ago.
