BritainImported Wheat 2,000 Years before Growing It

英国小麦进口比本土种植早2000年

Early farming began in the Near East about 10,500 years ago. Farming first reached the Balkans in Europe some 8[,000] to 9,000 years ago, and then crept westward. Locals in Britain, separated from the mainland by the relatively newly formed English Channel, did not start farming until about 6,000 years ago.

近东地区的早期农业种植大约始于10500年前。约在8到9千年前,农业最先到达欧洲的巴尔干半岛地区,然后渐渐向西延伸。由于被相对来说新形成的英吉利海峡从欧洲大陆分隔了出来,英国本土人民直到约6000年前才开始耕种。

\But an analysis of sediment from a submerged British archaeological site called Bouldner Cliff found something unexpected.

但一份对于一个沉积物的分析使研究人员有了意外发现。该沉积物出自英国一个名为伯德那悬崖的水下考古遗址中。

Amongst our Bouldner Cliff samples we found ancient DNA evidence of wheat at the site, which was not seen in mainland Britain for another 2,000 years. Robin Allaby of the University of Warwick.

在;伯德那悬崖;遗址找到的样品中,我们发现了古代小麦基因。而这种小麦2000年后才在英国大陆上种植。华威大学的罗宾阿勒比说。

However, wheat was already being grown in southern Europe. This is incredibly exciting because it means Bouldner;s inhabitants were not as isolated as previously thought. In fact, they were in touch, one way or another, with more advanced Neolithic farming communities in southern Europe. The work by Allaby and colleagues is in the journal Science.

然而,此时小麦已经在欧洲南部种植。这非常令人兴奋,因为它意味着伯德那的居民并不像先前人们认为的那么孤立。事实上,他们以某种方式跟欧洲南部更先进的处于新石器时代的农业社区有着联系。阿勒比和同事们的研究发表于《科学》杂志。

The researchers showed that the wheat remains are genetically more similar to Near Eastern domesticated wheat than to local distant cousins. And they found no evidence of pollenmeaning that the wheat was almost certainly imported.

研究人员表示:从基因上看,比起本地的小麦品种被发现的小麦更类似于近东地区种植的小麦。他们并没有发现花粉存在的迹象这就意味着几乎可以确定这种小麦是进口的。

In an accompanying Perspectives piece in the journal, archaeologist Greger Larsen of Durham University writes that the findings show that DNA analysis can help scientists tease out details about the historical movement of plant and animal species.

在该杂志随后发表的观点中,杜伦大学的考古学家格雷格拉森写道:该研究结果表明,基因分析可以帮助科学家梳理出有关动植物物种历史运动的细节。
