ABSTRACT
Archaeogenetic research over the last decade has demonstrated that European Neolithic farmers (ENFs) were descended primarily from Anatolian Neolithic farmers (ANFs). ENFs, including early Neolithic central European Linearbandkeramik (LBK) farming communities, also harbored ancestry from European Mesolithic hunter gatherers (WHGs) to varying extents, reflecting admixture between ENFs and WHGs. However, the timing and other details of this process are still imperfectly understood. In this report, we provide a bioarchaeological analysis of three individuals interred at the Brunn 2 site of the Brunn am Gebirge-Wolfholz archeological complex, one of the oldest LBK sites in central Europe. Two of the individuals had a mixture of WHG-related and ANF-related ancestry, one of them with approximately 50% of each, while the third individual had approximately all ANF-related ancestry. Stable carbon and nitrogen isotope ratios for all three individuals were within the range of variation reflecting diets of other Neolithic agrarian populations. Strontium isotope analysis revealed that the ~50% WHG-ANF individual was non-local to the Brunn 2 area. Overall, our data indicate interbreeding between incoming farmers, whose ancestors ultimately came from western Anatolia, and local HGs, starting within the first few generations of the arrival of the former in central Europe, as well as highlighting the integrative nature and composition of the early LBK communities.

     Reich与占士邦的老同事再次联手出击,估计会有一些看头的,呵呵

        光顾着咱们东亚人祖先,现在关心一下远方的欧洲远亲们。
        在维度不多的情况下,PCA还是值得一看的~

   虽说是挂名大牛Lipson, Reich的论文,当时比咱们天朝现在的硕士研究生的学位答辩论文差远了,呵呵

   大致上,估计东亚情况与欧洲早期农业人群的形成大致相似,北上的长江中下游农夫来到黄河之南,与当地旧石器土著混合,形成黄河农夫,EAS1人群开始逐渐成型~~

欧洲不是农业的发源地,所以拿来和中国相比本来就是不适合的。真要和中国相比的话,需要中东加欧洲才能和中国相提并论。

     我的意思是,欧洲(主要是中低维度地区,前期以LBK文化区域为代表)相当于黄淮地区,而小亚相当于长江中下游~
