It is not unusual for archaeologists to find traces of crushed grains on grinding stones over 30, 000 years old, but they do not attribute this to baking technology. Rather, ancient people split hard grains like nuts before eating. And the time of the appearance of real bread, which will be the first step on the path to agriculture and a sedentary lifestyle, is constantly shifting. Recently, a new record was set - 12, 000 BC.
In the Black Desert of Jordan, in a place called Shubayka-1, in the period 2012-2015. During the excavations, the huts of the Natuf hunter-gatherers were discovered, which were distinguished from others by the presence of a stone hearth. And inside - charred bone fragments and plant remains. Recently, an international team of scientists completed a detailed analysis of 24 surviving fragments and concluded that these are the oldest bread crumbs in the world.
DNA analysis showed that the oats, einkorn wheat and barley in the samples are wild versions of modern cereals that have not yet been bred. The grains were crushed, sieved, mixed and kneaded into dough before heat treatment. The result is very similar to the unleavened cakes from the Neolithic sites in southern Europe and Turkey. And this is another proof - people first learned how to bake bread, then they appreciated the benefits of such food, and this prompted them to start cultivating the land and sowing cereals.
Another indirect discovery is that the process of making bread from small and hard grains of wild plants was many times more complicated than modern baking from flour. However, laborious work produced such a product that had no analogues in nature, and therefore such food quickly became a privileged one. And the tribes who know how to make it got a chance to make a revolution, a breakthrough in their development. But this hypothesis requires more evidence than scientists have now.
