Mixing between Neolithic Farmers and Mesolithic Hunter-Gatherers

Paleogenomic Evidence for Multi-generational Mixing between Neolithic Farmers and Mesolithic Hunter-Gatherers in the Lower Danube Basin

The transition from hunting and gathering to farming involved profound cultural and technological changes. In Western and Central Europe, these changes occurred rapidly and synchronously after the arrival of early farmers of Anatolian origin [1, 2, 3], who largely replaced the local Mesolithic hunter-gatherers [1, 4, 5, 6]. Further east, in the Baltic region, the transition was gradual, with little or no genetic input from incoming farmers [7]. Here we use ancient DNA to investigate the relationship between hunter-gatherers and farmers in the Lower Danube basin, a geographically intermediate area that is characterized by a rapid Neolithic transition but also by the presence of archaeological evidence that points to cultural exchange, and thus possible admixture, between hunter-gatherers and farmers. We recovered four human paleogenomes (1.1× to 4.1× coverage) from Romania spanning a time transect between 8.8 thousand years ago (kya) and 5.4 kya and supplemented them with two Mesolithic genomes (1.7× and 5.3×) from Spain to provide further context on the genetic background of Mesolithic Europe. Our results show major Western hunter-gatherer (WHG) ancestry in a Romanian Eneolithic sample with a minor, but sizeable, contribution from Anatolian farmers, suggesting multiple admixture events between hunter-gatherers and farmers. Dietary stable-isotope analysis of this sample suggests a mixed terrestrial/aquatic diet. Our results provide support for complex interactions among hunter-gatherers and farmers in the Danube basin, demonstrating that in some regions, demic and cultural diffusion were not mutually exclusive, but merely the ends of a continuum for the process of Neolithization.

很好啊。人类文明不是互相独立而是彼此相作用,它打断的是某个文明的停滞,促进了人类整体的进步。这就进一步反驳了人种替代论。西方人总算长点良心说实话了。

好就好在本文选 在文化剧烈变化而与此对应的人种却未发生同样剧烈变化的多脑河,很好地表达了人类文明进步是交流而非敌视。

作者团队似乎是一个女子组合,其中第二作者赫然是可爱的琼斯博士,蛮有意思的Gloria González-Fortes, Eppie R. Jones14,, Emma Lightfoot, Clive Bonsall, Catalin Lazar, Aurora Grandal-d’Anglade, María Dolores Garralda,, Veronika Siska, Angela Simalcsik, Adina Boroneanţ。指导老师Michael Hofreiter不太熟,不记得他之前有什么拿得出手的作品...

Highlights
...
•A large WHG genome component was present in Eneolithic communities in this region
•The further east in Europe, the weaker the genetic component of Anatolian farmers

正好印证之前lazaridis的检测结果,颜那亚古人的CHG不是来自欧洲方向,而是来自里海南部的伊朗铜石人群~

看完欧洲人的论文,感觉东亚这边在古人类基因研究上几乎是停滞的

看来还是导师不得力,女子兵团这一次的作业依然是差强人意,比如以CHG来替代之前的ANE作为欧洲青铜早期的三大成分之一,合适吗?除非这个‘欧洲’仅限于巴尔干以及南欧地区。
看来指望分子人类学女子兵团中出现一个付大美也是挺不容易的,呵呵
