欧洲农业大约在9000年前起源于近东。新石器时代在距今5000年前（在现在之前）几乎到达了所有适合农业的地区2,4。农业在欧洲传播的路线和时间已经相对确定了，但传播的方式还没有确定。这可能是由于文化传播，几乎没有遗传后果。相比之下，Ammerman和Cavalli-Sforza2提出，农业的传播增加了当地的人口密度，导致人口向新的领土扩张，并在新石器时代的农民和中石器时代的群体之间扩散基因流动。我们现在已经测试了观察到的遗传模式，而不是从疫情扩张假设中得出的预期。当地理距离保持不变时，我们发现遗传距离与专门设计用于表示该大陆农业传播的距离矩阵之间存在显著的部分相关性。这些发现支持了Ammerman和Cavalli-Sforza的假设，并对Renfrew关于印欧语言起源的假设进行了进一步的调查。
EUROPEAN agriculture originated in the Near East about 9,000 years ago1–3. The Neolithic reached almost all areas suitable for agriculture by 5,000 yr BP (before present)2,4. The routes and times of the spread of agriculture through Europe are relatively well established2,3,5, but not its manner of spreading6–8. This could have been by cultural diffusion with few genetic consequences. By contrast, Ammerman and Cavalli-Sforza2 proposed that the spread of farming increased local population densities, causing demic expansion into new territory and diffusive gene flow between the neolithic farmers and mesolithic groups. We have now tested observed genetic patterns against expectations derived from the demic expansion hypothesis. We found significant partial correlations of genetic distances with a distance matrix especially designed to represent the spread of agriculture on that continent, when geographic distances are held constant. These findings support the hypothesis of Ammerman and Cavalli-Sforza and invite further investigation into Renfrew's hypothesis on the origin of the Indo-European languages.
