项目摘要

The adoption of a cereal-based diet set in train some of the most fundamental shifts in the global history of modern humans, yet the process by which this was introduced into many parts of the world is not understood. More specifically, at locations where conditions were not favourable for cereal agriculture, a number of models have been put forward, proposing a staggered, drawn-out or even failed introduction of a cereal-based economy as alternatives to a swift and full-blown appearance of the entire farming 'package' of crops and livestock. This is important for determining i) the social mechanism by which farming spread across Europe and hence its societal impact and ii) the extent to which environmental and climatic constraints had to be overcome to establish agriculture in the long-term. However, testing this on a large scale is challenged by uncertainties in the archaeological record, which hampers our understanding of the adoption and adaptation of farming.Here we propose tackling this through developing a methodology that enables us to trace the importance of cereal products in prehistory through biological markers (biomarkers) left in archaeological pottery used to process them. Reconstructing dietary change through patterns in fat (lipid) molecules extracted from the pores of unglazed pottery vessels is now a well-established approach that has developed over the course of over four decades. These preserved fingerprints in pots have enabled major patterns in human subsistence to be reconstructed, including earliest direct evidence for dairying in Europe and an abrupt and sustained shift away from marine economies in the British Isles lasting nearly 5000 years. Much previous research has focused upon fats of animal origin; however, plant foods such as cereals, which ultimately became a key staple in many societies across the world at some point in time, are currently invisible using this approach. This is because cereals are low in fat content compared with animal fats, and because no identifying signature has yet been established that would attribute lipid residues of cereal origin unambiguously to this source.We propose to address this through developing a novel 'paleolipidomics' approach: that involves looking at the whole profile of the components of modern grain lipids and in particular characterizing minor classes that together may act as identifiers for cereal-processing. Through degradation experiments, we will confirm the most robust suite of markers that will survive over archaeological timescales and then test their persistence through analysis of archaeological pottery sherds from Iron Age Britain and Neolithic Germany where there is strong archaeological evidence for a cereal-based economy. We will then employ a cutting-edge and highly sensitive analytical approach using accurate-mass gas chromatography-mass spectrometry to detect these signatures in archaeological pottery extracts from two key localities (Britain and the Eastern Baltic), testing the prevalence of cereal processing against models proposed for the introduction of farming to these regions ca. 6000 years ago.
以谷物为基础的饮食的采用引发了现代人类全球历史上一些最根本的转变,但这种饮食被引入世界许多地区的过程尚不清楚。更具体地说,在条件不利于谷物农业的地方,已经提出了一些模式,建议以交错、拖延甚至失败的方式引入以谷物为基础的经济,作为迅速全面出现作物和牲畜的整个农业“一揽子计划”的替代方案。这对于确定i)农业在整个欧洲传播的社会机制及其社会影响以及ii)必须克服环境和气候限制以建立长期农业的程度非常重要。然而,考古记录中的不确定性阻碍了我们对农业的采用和适应的理解,这对大规模测试提出了挑战。在这里,我们提出通过开发一种方法来解决这个问题,该方法使我们能够通过用于处理谷物产品的考古陶器中留下的生物标记(生物标志物)来追踪史前谷物产品的重要性。通过从未上釉的陶器容器的孔隙中提取的脂肪(脂质)分子的模式来重建饮食变化现在是一种经过四十多年发展的成熟方法。这些保存在罐子里的指纹使人类生存的主要模式得以重建,包括欧洲最早的直接证据,以及不列颠群岛持续近5000年的海洋经济的突然和持续转变。以前的许多研究都集中在动物来源的脂肪上;然而,谷物等植物性食物最终在某个时候成为世界上许多社会的主要主食,目前使用这种方法是不可见的。这是因为与动物脂肪相比,谷物的脂肪含量较低,而且还没有建立识别标志来将谷物来源的脂质残留明确地归因于该来源。我们建议通过开发一种新的“古脂质组学”方法来解决这个问题:这涉及到研究现代谷物脂质成分的整体概况,特别是表征可能共同起作用的次要类别,谷物加工的标识符。通过降解实验,我们将确认最强大的一套标志物,将生存在考古的时间尺度,然后通过分析考古陶器碎片从铁器时代的英国和新石器时代的德国,那里有一个以谷物为基础的经济强有力的考古证据来测试他们的持久性。然后,我们将采用一种尖端和高度灵敏的分析方法,使用准确的质量气相色谱-质谱法检测这些签名的考古陶器提取物从两个关键的地方(英国和波罗的海东部),测试谷物加工的流行对模型提出的农业引进这些地区约。六千年前。
