nding little supporteven in cranial studies) is disproved by genetic analysis.“Both the nuclear PCA and ADMIXTURE analysesindicated a very homogenous gene pool in the OkunevoCulture, in correspondence with the previous genetic studyof the Okunevo by Allentoft et al. (2015)” (Zacho, 2016: 38). However, the presence of several genetic componentsin the Okunev gene pool, indicating past admixture, asin the vast majority of known human groups, is apparent (see (Ibid.: App. 6)): apart from the “Native American”autosomal component proper, whose share is estimated at4.8 %, there is a Western Eurasian component, as Zachocalls it (61.8 %), and a Siberian component (32.6 %).The proportion of both the latter components is high in Native Americans, in the Malta boy (in his genome, the former component predominates), and in the Ust-Ishimmale, dating to ~45 ka BP (in whose genetic makeup bothcomponents are nearly equally represented) (Fu et al.,2014). The smallest component of the Okunev gene pool(0.8 %) is typical of Southeast Asians, making one recall the Far Eastern complex that L.A. Sokolova identi
“核PCA和混合分析均表明奥库尼沃文化中存在非常同质的基因库,这与Allentoft等人(2015年)之前对奥库尼沃进行的基因研究一致”(Zacho,2016:38)。然而,Okunev基因库中存在若干遗传成分,这表明在绝大多数已知的人类群体中,过去存在混合(见同上:App。6) ):除了“美洲原住民”常染色体组分(其比例估计为4.8%)之外,还有一个西欧亚组分(61.8%)和一个西伯利亚组分(32.6%)。后两个组分在美洲原住民中的比例很高,在马耳他男孩中(在他的基因组中,前一组分占优势),在Ust-Ishimmale,可追溯到约45千年BP(在其基因构成中,两种成分的代表性几乎相同)(Fu等人,2014年)。Okunev基因库中最小的部分(0.8%)是典型的东南亚人,让人想起L.A.Sokolova识别的远东复合体
