archaeologist have uncovered the earliest evidence of bread - making at a site in northeast Jordan . Dating back some 14,400 twelvemonth , the discovery depict that ancient huntsman - gatherer were making and eating shekels 4,000 years before the Neolithic era and the introduction of agriculture . So much for the “ Paleo Diet ” in reality being a matter .
Bread - making predates husbandry , accordingto a unexampled subject field published today in Proceedings of the National Academy of Sciences . That ’s quite the revealing , hand the conventional thinking that bread only appear after the advent of agriculture . The breakthrough means that ancient hunter - collector were using the crazy ancestors of reclaim cereal , such as wild einkorn and club - rush tubers , to make flatbread - like solid food products . What ’s more , the new composition exhibit that bread had already become an launch food staple prior to the Neolithic time period and the Agricultural Revolution .
A inquiry squad led by Amaia Arranz - Otaegu from the University of Copenhagen analyzed fragment of charred food remains found at a Natufian hunter - gatherer situation in northeastern Jordan hollo Shubayqa 1 . The clay of the burn bread , find in two ancient basalt - stone fireplace , were carbon 14 see to 14,400 years ago , give or take a couple of hundred years . This corresponds to the early Natufian period and the Upper Paleolithic era . The Natufian culture lived in the Levant , a region in the Eastern Mediterranean , from around 14,600 to 11,600 years ago .
Prior to this breakthrough , the oldest known bread issue forth from the 9,500 - twelvemonth - old settlement of Çatalhöyük , located in Anatolia , Turkey . Çatalhöyük date stamp back to the Neolithic earned run average , a time when ancient humans had already adjudicate in lasting small town and developed farming . The bread found at Shubayqa 1 pre - date the Çatalhöyük boodle by around 5,000 geezerhood , and it ’s now the oldest example of bread - making in the archaeological record .
For the study , the researchers analyze 24 charred fragments of bread from the Shubayqa 1 digging web site using a Scanning Electron Microscope ( SEM ) . Using SEM , the investigator were able to obtain the high resolution images required for studying the o.k. structures embedded within the char materials . These images were compare to experimentally bring forth bread , allowing the researchers to identify the archaeological specimens . SEM analysis is quite time consuming , and the researchers only get by to analyze 24 fragment out of a totality of 600 pieces that come out to be bread or bread - like remains .
Tobias Richter , an associate professor at the University of Copenhagen and a carbon monoxide gas - author of the new study , say the discovery was surprising on a number of stratum .
“ First , that bread predates the Second Advent of agriculture and land — it was always consider that it was the other way orotund , ” Richter distinguish Gizmodo . “ secondly , that the bread was of high quality , since it was made using quite fine flour . We did n’t ask to discover such high - quality flour this ahead of time on in human story . Third , the hunter - collector bread we have does not only contain flour from barbarian barleycorn , wheat and oats , but also from tubers , namely tubers from piddle plant life ( sedges ) . The bread was therefore more of a multi - grain - tuber bread , rather than a white loaf of bread . ”
Richter said the method acting used for identify the bread fragments is new , and that other investigator should expend the technique to re - analyze older archaeological collections to search for even early good example of breadstuff output .
“ I mean it ’s quite significant to realise that bread is such a hugely crucial staple in the world today , ” say Richter . “ That it can now be show to have started a mountain earlier than previously reckon is quite intriguing , I think , and may help to excuse the huge variety of unlike types of breads that have develop in dissimilar culture around the domain over the millennia .
Dorian Fuller , an archaeobotanist at the University College London and a co - author of the new work , said it ’s extremely plausible that hunter - accumulator were able to make bread without the welfare of farming .
“ Bread at it its most basic is flour , weewee , and dry heat energy . The flour should also ideally include some protein , such as gluten , that occurs in wheat to contain the batter together and provide elasticity , ” Fuller told Gizmodo . “ So this requires a suitable flour , and wild straw and barleys contain gluten . ”
In improver , the necessary equipment to produce flour , like Harlan Fisk Stone tools to pulverize grains , were already in existence by the metre this ancient bread was made , as some of the oldest examples date back 25,000 years or more . “ So the fact that people would have ground clobber to process it is not surprising , ” say Richter . in conclusion , the third component to give sugar — dry , baking heat — would likely survive in a culture without ceramics , which key out this particular culture at the time .
Ehud Weiss , an archaeobotanist at Bar - Ilan University who was n’t involved with the new subject , says the new paper describes a significant uncovering .
“ One of the interesting aspect of reconstructing our ancestors ’ diet is the engineering they used , ” Weiss evidence Gizmodo . “ Here , it is clear these citizenry crunch and mixed several types of foodstuff , cereal grass , and root food to create a baked product . ”
Weiss says it ’s important to remember that caloric return was a major issuance with hunter - gatherers ’ diet , especially in intriguing environments . basis and adust foodstuffs have a higher glycemic power ( GI ) than raw food , where GI is a relative ranking of sugar in foods according to how they regard blood glucose levels .
“ Today , we apply GI as a putz to avoid food for thought that will add too much sugars to our stock stream , ” say Weiss . For Orion - gatherers who struggle in uncongenial environments to gain more energy from their food , the situation is , of course , the opponent . The power to increase the caloric return from their food is , therefore , an important step in the growth of human nutrition . ”
Francesca Balossi Restelli from the Sapienza University of Rome , also not involved with the fresh study , was n’t storm by the finding , saying a breakthrough of this nature was expected .
“ sure , find out coal corpse of flour product is the much - needed demonstration of what the large quantity of mortar , pestles , and moulders were already showing us , ” Restelli state Gizmodo . “ If masses were cultivating plant , if they had mortars , then they must have been bake ‘ cabbage - similar ’ food for thought . The discovery described in the PNAS article is thus certainly passing meaningful , but not totally unexpected . It is very nice word , as it support today ’s trend of thought and inquiry . ”
University of Cambridge archaeobotanist Martin Jones is excited about the new paper , both for what it tell about about the dietetic habits of palaeolithic humans , and in the function of a new technique to study the bits and piece of plant material get out behind by ancient humans .
“ If we listen to many of the familiar narration about how humans deplete before the advent of agriculture , we hear a great deal about animals , and a bite about seafood , ” Jones distinguish Gizmodo . “ We have got nowhere near as far with understanding how they work with plants , and it is beginning to come decipherable that plant - found cuisine is very old indeed , and very substantial . ”
“ Looking at pulverized plant material is still quite fresh , ” Jones say . “ We archaeobotanists clearly palpate more confident about identifying industrial plant before they have been mashed to a pulp magazine . But the SEMs here show how much cellular formula is still discernible , and how fruitful it can be to persevere and give it a closer look . ”
As a final note , this study remind us , yet again , that the so - called Paleo Diet is n’t an actual thing , or at the very least , not a logical , unified dieting that existed across multiple universe of paleolithic peoples . What ’s more , this field of study does n’t tell us which particular ancestral diet was the “ healthiest , ” and it ’s doubtful that archaeology can assure us anything meaningful in this wish . When it fall to a balanced , healthy dieting , you should hear to the experts : Eat lots of vegetables and yield , choose whole grains , get your protein , and forefend extremely processed foods , particularly those with added sugar .
