Despite being one of the most important foodstuffs consumed in the modern world, the origins of bread are still largely unknown. But archaeologists report the earliest empirical evidence for the preparation of bread-like products by Natufian hunter-gatherers, 4,000 years before the emergence of the Neolithic agricultural way of life. The findings come from Shubayqa 1,  a hunter-gatherer site  located in northeast Jordan, in an area known as the Black Desert.

The results suggest the use of the wild ancestors of domesticated cereals (e.g. wild einkorn) and club-rush tubers to produce flat bread-like products. Cereal-based meals such as bread probably become staples when Neolithic farmers started to rely on the cultivation of domesticated cereal species for their subsistence.
