A DNA analysis of wheat found in an ancient peat bog suggests other Britons were more commercially sophisticated than previously thought . The comportment of wheat on the British Isles a full 2,000 twelvemonth before farmers began cultivate cereal grains means these hunting watch - gatherers may have established important swap connections in Europe .
Archaeologist believe that farming did n’t get hold of the British Isles until about 6,000 eld ago . But the discovery of wheat submerged under 36 feet ( 11 measure ) of water just off the Isle of Wight indicates that it may have arrive in Britain by some other means 2,000 years prior .
ScienceNow ’s Michael Balterexplains :
The site was clearly occupied by hunter - gatherers , who may have built wooden boats . [ The ] squad assume four pith samples of sediments from a section of the situation litter with burnt hazel shells plain will by the hunter - collector and subjected the sample distribution to both radiocarbon date and ancient DNA analytic thinking . The samples ’ wood and plant were date to between 8020 and 7980 years ago , after which the internet site was inundated by the rising sea that make the English Channel and part Britain from France .
For the ancient DNA analytic thinking , the team used methods pioneered by paleogeneticist Eske Willerslev of the University of Copenhagen torecover and sequence genetic materialleft behind in sediments even after the plant that in the first place contained it have disintegrate . As might be expect , Allaby and his colleagues found DNA from a wide variety of tree and industrial plant eff to have populate southerly Britain 8000 days ago , include oak , poplar , and beech , along with various smoke and herbs . But the team also produce a big surprise : Among the deoxyribonucleic acid samples were two type of domesticated wheat that originated in the Middle East and that have no wild ancestors in northern Europe . That meant they must have been associated with the original ranch of agriculture from the Middle East , beginning about 10,500 class ago , rather than domesticated locally . Yet many archaeologists seize that by 8000 age ago farming was no further west than the Balkans region and modernistic Hungary . [ accent sum ]
That ’s a surprise , one that ’s resetting our notions of when Western Europeans and Britons transitioned from the Mesolithic to the Neolithic era , i.e. when hunter - gatherer made the jump to farming .
The researchers do n’t believe the wheat was cultivate by the hunting watch - gatherer themselves as no wheat pollen was found in the sample . Rather , they suspect that farming spread to westerly France earlier than assumed — about 7,600 years ago . Alternately , roving Orion - gatherers of southern Britain may have ventured deeper into Europe than we realized . To do so , they would have found trade connection and the requisite boating technologies to travel across the Channel . Or maybe Europeans come to them .
But not everyone is confident . Writing in Nature News , Quirin Schiermeierexplains :
“ Archaeology perpetually throws up surprises , but these findings look baffle to me , ” says Peter Rowley - Conwy , an archaeologist at Durham University , UK . He point out that farming had hardly scatter north of the Danube 8,000 age ago . “ This seems too far for hunter - accumulator web to unfold , ” he suppose . “ artefact such as Flint River blades and arrowheads that appeared around that time from Portugal to the Urals never made it to Britain — it ’s voiceless to believe that wheat should . ”
The findings ask to be confirmed in the greater context of existing archaeological research , he says . But Mesolithic settlements that could shake off spark on the effect are hard to find in mainland Britain . To understand how and when Neolithic culture arrived , tell Allaby , “ the result probably lie under the ocean ” .
Indeed , more grounds needs to be collected to make a more certain promulgation .
It ’s conceivable , for example , that it was just a one - off thing , or something limited to a very small population . Nonetheless , it ’s a fascinating discovery that ’s pass on British archeologists plenty to think about .
