sag这个是有争议的,有人认为是卡拉苏克II期文化,有人认为是一种平行文化(时间比卡拉苏克I期晚)。

sag的核心区在阿尔泰东北坡,而卡拉苏克核心区在南西伯利亚地区(环萨彦-阿尔泰)的西北部,可能在sag期的时候,卡拉苏克I期已经被其他文化覆盖了。

发现最近论坛流行挖坟,很多老帖子都被挖出来了。

在2016年9月的ISBA7会议(7th International Symposium on Biomolecular Archeology)上,王传超做过一个报告。在乌苏里江附近某地区现代人常染色体几千年来相对连续变化这一点上,与一楼的文章的结论相同。

王的报告涉及关于整个东亚人群DNA演化的研究,众多合作者也包括坛主。但愿正式文章很快会出来。报告摘要里的东西和最近这些天论坛上的不少讨论帖的内容都相关。我把它抄在下面。

Reconstructing population history in East Asia

Abstract:
The deep population history of East Asia remains poorly understood compared to that of West Eurasia, due to the lack of ancient DNA data as well as limited sampling of present-day populations especially on the Tibetan Plateau and in southern China. We report a fine scale survey of East Asian history based on genome-wide data from ancient samples in the Amur River Basin, as well as 435 newly reported individuals from 53 populations. Present-day groups can be broadly classified into highly differentiated clusters, corresponding to Amur River Basin, Tibetan Plateau, southern natives and Han Chinese. Populations of the Amur River Basin show a high degree of genetic continuity from seven thousand years ago until today, and are closely related to the strain of East Asian related ancestry present in Native Americans. Tibetan Plateau populations are all admixed, deriving about 5%-10% of their ancestry from an anciently divergent population that plausibly corresponds to the Paleolithic population on the Plateau, and the remaining part from an ancient population that no longer exists in unmixed form but that likely corresponds to expanding farmers from the Middle and Upper Yellow River Basin who also contributed 40-90% of the ancestry of Han Chinese. A total of 10-60% of Han Chinese ancestry derives from southern Native populations, and we show that the type of southern Native ancestry that contributed to Taiwan Island Austronesian speakers is most closely related to present-day speakers of Tai-Kadai languages in southern mainland China.
只有一个古人标尺,结论都不必当真,看看欧洲就知道,你光看克鲁马农和LBK古dna,是永远找不到欧洲的三波核心祖先颜那亚人的。

从内容上看,分得很粗,对论坛上的讨论没有帮助。

之前在Eupedia上有一个johen的高级会员,对欧洲学界为何长期忽视奥库涅夫文化感到大惑不解,这篇帖子很有意思,里面好几个会员贴出来许多很有启迪性的文献资料:
http://www.eupedia.com/forum/threads/33484-why-Okunevo-culture-was-ingored-in-Indo-European-history-they-are-just-paleo-people
里面有很多关于奥库涅夫文化平时看不到的图片资料。令人惊奇的是,奥库涅夫文化在许多方面与美洲土著文化有明显的相似之处,可能与y-Q人群有关~

这个分析结果,正好与本坛主流观点是一致的,不过可能小云老师会有不同的看法~
