Ancient DNA studies have shown that early farming spread through most of Europe by the range expansion of farmers of Anatolian origin rather than by the conversion to farming of the local hunter-gatherers, and have confirmed that these hunter-gatherers continued to coexist with the incoming farmers. In this short report, I extend a previous three-population wave-of-advance model to accommodate these new findings, and derive the conditions supportive of such a scenario in terms of the relative magnitudes of the parameters. The revised model predicts that the conversion rate must, not surprisingly, be low, but also that the hunter-gatherers must compete more strongly with the converted farmers than with the alien farmers. Moreover, competition with the hunter-gatherers diminishes the speed of the wave-of advance of the farmers. In addition, I briefly consider how the wave-of-advance approach may contribute to interpreting the results of archaeological studies using the summed probability distribution of radiocarbon dates.
古 DNA 研究表明，早期的农业通过安纳托利亚起源的农民的范围扩张而不是通过当地狩猎采集者向农业的转变在欧洲大部分地区传播，并且已经证实这些狩猎采集者继续与新来的农民共存。在这个简短的报告中，我扩展了之前的三人群体推进波模型，以适应这些新发现，并根据参数的相对大小推导出支持这种情况的条件。修正后的模型预测，转换率必须很低，这并不奇怪，但狩猎采集者必须比与外来农民竞争更激烈的转化农民竞争。此外，与狩猎采集者的竞争会降低农民推进波的速度。此外，我还简要地考虑了推进波方法如何有助于解释使用放射性碳日期总和概率分布的考古研究结果。
