Preliminary Impression of Current Dental Anthropology Research in China
... Межгрупповой статистический анализ проведен на основе тригонометрически преобразованных частот 7 важных для дифференциации восточноевразийских групп признаков: лопатообразность I 1 , бугорок карабелли M 1 , шестибугорковый М 1 , четырехбугорковый М 2 , tami М 1 , дистальный гребень тригонида М 1 и коленчатая складка метаконида М 1 . анализ выполнен методом главных компонент (гк) в программе Statistica 10. в качестве сравнительных данных привлечены серии эпох неолита и бронзы с территории сибири, дальнего востока, китая и японии [зубов 1980;Wu, Xianglong 1995;Kaburagi et al. 2010 результАты и обсужДение серия глазковской культуры из могильника туаханэ IX характеризуется абсолютным распространением лопатообразной формы верхних резцов и клыков (табл. 2). ...
The new updated cultural and chronological periodization of the Cis-Baikal region, suggesting the absence of continuity between the Kitoy and Serovo–Glazkovo culture, actualizes the problem of the origin of the late Neolithic and Early Bronze Age populations of the region. The purpose of this study is to reveal the biological affinities of the Cis-Olkhon Glazkovo population from the Tuakhane IX burial ground based on the analysis of non-metric dental morphology data. The original data set includes dental characteristics of 12 individuals from the Tuakhane IX burial place, including 2 males, 3 females, 4 children and 3 individuals whose sex and age could not be determined. In the study both the extended battery of dental traits generally accepted by Russian researchers and ASUDAS scale were used. The results of the analysis reveal that while the Tuakhane IX Glazkovo group morphologically undoubtedly belongs to the Eastern mongoloid population and its morphological specificity is similar to the Late Neolithic Serovo and Early Bronze Ages Glazkovo populations of the Cis-Baikal area. Significant differences between the Serovo–Glazkovo groups from the Kitoi groups were demonstrated. This confirms the results of the archaeological and genetics studies which argued for a lack of continuity between Early Neolithic and Late Neolithic–Early Bronze Age populations in the Cis-Baikal region. The dental data indicate the migration of Far Eastern groups from Primoye to the Cis-Baikal area and their significant influence on the dental morphology of the Late Neolithic Serovo people. Remarkably, the Glazkovo sample from Tuakhane IX is characterized by the similar morphologic specificity. Also the specific trait combination that differentiates Glazkovo people from the Neolithic Baikal and Far East groups was identified and which, apparently, can be the result of a gene flow from the Ymyyakhtakh Early Bronze Age populations of Yakutia to the Glazkovo people. In addition, dental data support the hypothesis about possible migration of the Cis-Baikal tribes to the Western Siberian forest-steppe, which has been repeatedly put forward on the basis of results of archaeological and anthropological studies.
... Серия была обследована на основании двух исследовательских программотечественной [Зубов, 2006], и системы Аризонского Университета [Turner, Nichol, Scott, 1991]. Полученные данные были сопоставлены при помощи многомерной статистики с одонтологической серией бойсманской неолитической культуры (неопубликованные данные Зубовой), с характеристиками носителей культурных традиций эпохи дземон и сацумон [Kaburagi et al., 2009], китойской, серовской и глазковской культур эпохи неолита -бронзы байкальского региона, ымыяхтахской поздненеолитической культуры Якутии (неопубликованные данные Зубовой), и неолитическими сериями с территории Китая [Fu, 1994;Wu, Xianglong, 1995]. Также к анализу была привлечена серия янковской культуры первой полвины I тыс. ...

В результате оказалось, что бойсманская группа отличается от всех привлеченных к анализу неолитических выборок. ...
The recently described Denisovan hemimandible from Xiahe, China [F. Chen et al., (2019) Nature 569, 409–412], possesses an unusual dental feature: a 3-rooted lower second molar. A survey of the clinical and bioarchaeological literature demonstrates that the 3-rooted lower molar is rare (less than 3.5% occurrence) in non-Asian Homo sapiens . In contrast, its presence in Asian-derived populations can exceed 40% in China and the New World. It has long been thought that the prevalence of 3-rooted lower molars in Asia is a relatively late acquisition occurring well after the origin and dispersal of H. sapiens . However, the presence of a 3-rooted lower second molar in this 160,000-y-old fossil hominin suggests greater antiquity for the trait. Importantly, it also provides morphological evidence of a strong link between archaic and recent Asian H. sapiens populations. This link provides compelling evidence that modern Asian lineages acquired the 3-rooted lower molar via introgression from Denisovans.
