In 2018, a team of researchers from the University of Copenhagen, the
University College London, and the University of Cambridge released a
paper in the "Proceedings of the National Academy of Sciences" detailing
their discovery of 14,400-year-old crumbs from a flatbread. The
archaeological site, known as Shubayqa 1, is located in the Black Desert
of northeastern Jordan and was home to Natufian hunter-gatherers. The
flatbread remains are not only the oldest instance of bread found to
date, but also preeminent examples of how bread-making existed even
before agriculture developed some 4,000 years later.
