论文摘要
最近，Mikheyev等。 （2019年）进行了一项预印本研究，描述了从7世纪至9世纪在现代俄罗斯的罗斯托夫县发现的九个考古学的基因组。头骨形态表明“高加索”和“蒙古人”形状的混合物。作者将样本与古代和当代样本进行了比较，以研究Khazars及其遗传遗产的遗传构成，并解决了Khazar和Ashkenazic犹太人之间关系的问题。仔细检查表明，从“卡萨尔”样品的识别，古代DNA测序环境的选择以及分析中，对研究的所有方面都感到严重关切。作者没有透露其研究中使用的数据，他们的方法论是不连贯的。我们证明他们的分析产生了荒谬的结果，并认为本研究中提出的任何主张均无明确地支持。如果骨骼样本的破坏和分析的不可培养性，即使是根据该领域的宽恕标准，这项研究都是无法复制，浪费和误导的。
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.
