中世纪草原游牧征服者的多样遗传起源-对Mikheyev等人的回应。
Diverse genetic origins of medieval steppe nomad conquerors -- a response to Mikheyev et al. (2019)
摘要：
最近，Mikheyev等人（2019年）制作了一份预印本研究，描述了在现代俄罗斯罗斯托夫县发现的9个可萨人的基因组，这些可萨人的考古学日期为7世纪至9世纪。头骨形态显示“高加索人”和“蒙古人”的混合形状。作者将这些样本与古代和当代样本进行了比较，以研究可萨人的基因组成及其遗传遗产，并解决了可萨人和德系犹太人之间的关系问题。仔细的检查揭示了对研究的所有方面的严重关注，从“哈扎尔”样本的鉴定，古代DNA测序的环境选择和分析。作者没有透露他们研究中使用的数据，他们的方法也不连贯。我们证明了他们的分析产生了无意义的结果，并认为这项研究中提出的任何主张都没有得到数据的明确支持。如果骨头样本被破坏，分析结果无法重现，即使按照该领域的可原谅标准，这项研究也是不可复制的，浪费的，误导的。
英文摘要：
Recently, Mikheyev et al. (2019) have produced a preprint study describing the genomes of nine Khazars archeologically dated from the 7th to the 9th centuries found in the Rostov county in modern-day Russia. Skull morphology indicated a mix of "Caucasoid" and "Mongoloid" shapes. The authors compared the samples to ancient and contemporary samples to study the genetic makeup of the Khazars and their genetic legacy and addressed the question of the relationships between the Khazar and Ashkenazic Jews. A careful examination reveals grave concerns regarding all the aspects of the study from the identification of the "Khazar" samples, the choice of environment for ancient DNA sequencing, and the analyses. The authors did not disclose the data used in their study, and their methodology is incoherent. We demonstrate that their analyses yield nonsensical results and argue that none of the claims made in this study are supported by the data unequivocally. Provided the destruction of the bone samples and the irreproducibility of the analyses, even by the forgivable standards of the field, this study is irreplicable, wasteful, and misleading.
