14,400-year-old Bread Causes Major Re-think on the Birth of Agriculture
At an archaeological site in northeastern Jordan, researchers have discovered the charred remains of a flatbread baked by hunter-gatherers 14,400 years ago. It is the oldest direct evidence of bread found to date, predating the advent of agriculture by at least 4,000 years. The findings suggest that bread production based on wild cereals may have encouraged hunter-gatherers to cultivate cereals, and thus contributed to the agricultural revolution in the Neolithic period.
A team of researchers from the University of Copenhagen, University College London and University of Cambridge have analyzed charred food remains from a 14,400-year-old Natufian hunter-gatherer site - a site known as Shubayqa 1 - located in the Black Desert in northeastern Jordan. The results, which are now published in the journal Proceedings of the National Academy of Sciences , provide the earliest empirical evidence for the production of bread.
University of Copenhagen archaeobotanist Amaia Arranz Otaegui, who is the first author of the study, said:
"The presence of hundreds of charred food remains in the fireplaces from Shubayqa 1 is an exceptional find, and it has given us the chance to characterize 14,000-year-old food practices. The 24 remains analyzed in this study show that wild ancestors of domesticated cereals such as barley, einkorn, and oat had been ground, sieved and kneaded prior to cooking. The remains are very similar to unleavened flatbreads identified at several Neolithic and Roman sites in Europe and Turkey. So we now know that bread-like products were produced long before the development of farming. The next step is to evaluate if the production and consumption of bread influenced the emergence of plant cultivation and domestication at all."

University of Copenhagen archaeologist Tobias Richter, who led the excavations at Shubayqa 1 in Jordan further explained:
"Natufian hunter-gatherers are of particular interest to us because they lived through a transitional period when people became more sedentary and their diet began to change. Flint sickle blades as well as ground stone tools found at Natufian sites in the Levant have long led archaeologists to suspect that people had begun to exploit plants in a different and perhaps more effective way. But the flat bread found at Shubayqa 1 is the earliest evidence of bread making recovered so far, and it shows that baking was invented before we had plant cultivation. So this evidence confirms some of our ideas. Indeed, it may be that the early and extremely time-consuming production of bread based on wild cereals may have been one of the key driving forces behind the later agricultural revolution where wild cereals were cultivated to provide more convenient sources of food."
Charred remains under the microscope
The charred food remains were analyzed with electronic microscopy at a University College London lab by PhD candidate Lara Gonzalez Carratero (UCL Institute of Archaeology), who is an expert on prehistoric bread:
"The identification of 'bread' or other cereal-based products in archaeology is not straightforward. There has been a tendency to simplify classification without really testing it against an identification criteria. We have established a new set of criteria to identify flat bread, dough and porridge like products in the archaeological record. Using Scanning Electron Microscopy we identified the microstructures and particles of each charred food remain."
"Bread involves labor intensive processing which includes dehusking, grinding of cereals and kneading and baking. That it was produced before farming methods suggests it was seen as special, and the desire to make more of this special food probably contributed to the decision to begin to cultivate cereals. All of this relies on new methodological developments that allow us to identify the remains of bread from very small charred fragments using high magnification," said Professor Dorian Fuller (UCL Institute of Archaeology).

Research into prehistoric food practices continues
A grant recently awarded to the University of Copenhagen team will ensure that research into food making during the transition to the Neolithic will continue:
"The Danish Council for Independent Research has recently approved further funding for our work, which will allow us to investigate how people consumed different plants and animals in greater detail. Building on our research into early bread, this will in the future give us a better idea why certain ingredients were favored over others and were eventually selected for cultivation," said Tobias Richter.
The Shubayqa project research was funded by the Independent Research Fund Denmark. Permission to excavate was granted by the Department of Antiquities of Jordan.
