目前的证据表明，猪首先在公元前9千纪在安纳托利亚东部驯化，然后从7千纪开始随着新石器时代早期的农民分散到欧洲。最近的古DNA（aDNA）研究也表明，欧洲野猪在新石器化过程中融入了国内种群。为了确定家猪进入欧洲的时间，并测试关于欧洲野猪在驯化过程中所起作用的假设，我们结合了449个罗马尼亚古代牙齿的几何形态测量分析（使我们能够联合收割机结合牙齿的大小和形状）与aDNA分析。我们的研究结果首次证实了罗马尼亚第一批家猪具有与安纳托利亚西部和中部新石器时代猪相同的mtDNA特征的说法。其次，我们发现了一个显着比例的个人与大臼齿的牙齿形状相匹配的考古（可能）家猪。这些大型的“家养形状”标本从罗马尼亚新石器时代（公元前6100-5500卡尔）开始一直到后来的史前时期都存在，这表明引进的家猪和当地野猪之间有着悠久的混合历史。最后，我们证实了在家猪中发现的线粒体谱系的更替，这可能与史前晚期人类迁移到安纳托利亚和黎凡特的时间一致。
Current evidence suggests that pigs were first domesticated in Eastern Anatolia during the ninth millennium cal BC before dispersing into Europe with Early Neolithic farmers from the beginning of the seventh millennium. Recent ancient DNA (aDNA) research also indicates the incorporation of European wild boar into domestic stock during the Neolithization process. In order to establish the timing of the arrival of domestic pigs into Europe, and to test hypotheses regarding the role European wild boar played in the domestication process, we combined a geometric morphometric analysis (allowing us to combine tooth size and shape) of 449 Romanian ancient teeth with aDNA analysis. Our results firstly substantiate claims that the first domestic pigs in Romania possessed the same mtDNA signatures found in Neolithic pigs in west and central Anatolia. Second, we identified a significant proportion of individuals with large molars whose tooth shape matched that of archaeological (likely) domestic pigs. These large ‘domestic shape’ specimens were present from the outset of the Romanian Neolithic (6100–5500 cal BC) through to later prehistory, suggesting a long history of admixture between introduced domestic pigs and local wild boar. Finally, we confirmed a turnover in mitochondrial lineages found in domestic pigs, possibly coincident with human migration into Anatolia and the Levant that occurred in later prehistory.
