Ancient Northeast Asian

In archaeogenetics, the term Ancient Northeast Asian (ANA),[2][3] also known as Amur ancestry,[4] is the name given to an ancestral component that represents the lineage of the hunter-gatherer people of the 7th-4th millennia before present, in far-eastern Siberia, Mongolia and the Baikal regions. They are inferred to have diverged from Ancient East Asians about 24kya ago,[5] and are represented by several ancient human specimens found in archaeological excavations east of the Altai Mountains. They are a sub-group of the Ancient Northern East Asians (ANEA).[6]

Not to be confused with Ancient Northern East Asian (ANEA).
The Ancient Northeast Asians (ANA,   yellow area) are defined as a cluster of Neolithic populations from the Altai Mountains to the Pacific coast. They were bordered by Western Eurasian populations to the west, which combined BMAC, Afanasievo and Ancient North Eurasian (ANE) ancestry.[1]

Neolithic populations

The Prehistoric populations of Eastern Siberia are poorly understood, mainly due to the lack of archaeological specimens. So far, the oldest populations for which genomic data have been obtained are the Upper Paleolithic Ancient North Eurasians (c. 24,000 BP) from Central Siberia, and Upper-Paleolithic populations related to the "Basal-East Asian" Tianyuan man (c. 40,000 BP), specifically the Salkhit (c. 34,000 BP) and AR33K (c. 33,000 BP) samples from Mongolia and the Amur region, or Manchuria. There is then a large gap until the Neolithic period, where the specific ANA gene pool has been identified. Ancestry basal to the ANA gene pool, but significantly closer to them than to the Upper-Paleolithic Tianyuan-related gene pool or other East Asian lineages (such as Southern East Asians), has been found among a sample in the Amur region (AR19K; c. 19 000 BP), suggesting that Ancient Northeast Asians diverged from other East Asian populations sometimes between 19kya to 26kya.[8][9][10]

The first individual to be identified with the specific ANA gene pool came from the Russian Far East, near the Pacific coast, at the Devil’s Gate Cave ("DevilsCave_N", c. 5700 BCE).[11] More Neolithic individuals with the ANA gene pool have been identified in eastern Mongolia (SOU001, "EastMongolia_preBA" 4686–4495 cal. BCE), in central Mongolia (ERM003, "CentralMongolia_preBA" 3781–3639 cal. BCE), and four individuals from the eastern Baikal region ("Fofonovo_EN").[12] The closely related hunter-gatherers from the western Baikal region ("Baikal_EN", 5200–4200 BCE),[13][14] as well as the Early Bronze Age Baikal populations ("Baikal_EBA", circa 2500 BCE)[15] are generally included within the Ancient Northeast Asian cluster, although they are slightly differentiated from ANA samples through a minor ancestral component derived from Ancient North Eurasian (ANE) at c. 5-20%.[16][17][18]

The Devils_Cave_N sample was found to display genetic continuity with a c. 14kya sample (AR14K) from the Amur region, suggesting that the specific ANA gene pool formed as early as 14,000 BP.[9] Neolithic ANA remains have been found as far as the Altai Mountains, 1,500 km further to the west than previously understood.[19]

Later populations

Ulaanzuukh and Slab Grave cultures

The people of the Ulaanzuukh (1450–1150 BCE) and Slab Grave (1100–300 BCE) cultures were closely associated with the Ancient Northeast Asians and can be modeled as direct descendants.[20]

Tarim Mummies

A genomic study published in 2021 found that the Tarim mummies (c. 2000 BCE) had high levels of Ancient North Eurasian ancestry (c. 72%), with a smaller admixture from an Ancient Northeast Asian-like population (particularly the Baikal_EBA, at c. 28%), but no detectable Western Steppe Herder-related ancestry.[21][22]

Altai MLBA and Khövsgöl LBA
Khövsgöl LBA in the Middle-Late Bronze Age (1400 to 1100 BC) in Mongolia. Khövsgöl LBA is essentially composed of Baikal EBA ancestry   (itself essentially Ancient Northeast Asian, ANA  , with a small admixture from Ancient North Eurasian), and a relatively small admixture from a Sintashta-like source  .

Several successor groups with varying degrees of Sintashta admixture start to appear in the Altai region after this period. These groups formed from the westwards expansion of ANA-rich population from the Eastern Steppe and subsequent admixture from Western Steppe Herder migrant groups. This includes the Khövsgöl LBA[23] herders from northern Mongolia and the Altai MLBA hunter-gatherers from the Altai region.[24][12] The Khövsgöl LBA herders are descended from Early Bronze Age Baikal hunter-gatherers (Baikal EBA, c. 93%) with small amounts of admixture from Western Steppe Herders (Sintashta, c. 7%). Genetic analyses revealed that while dairy pastoralism seems to have been adopted by them from the Western Steppe Herders, they were primarily of local Northeast Asian origin, implying cultural transmission. Modern day Tuvinians are among the people sharing the highest genetic affinity with the Late Bronze Age herders of Khövsgöl.[25][26][27] The Altai MLBA gene pool further West can be associated with Eastern Scythians (Saka), who can be modeled as deriving significant amounts of ancestry (c. 40-55%) from the Baikal EBA groups, with additional Sintashta-like admixture (c. 45-60%).[28][29]

Sakas, Xiongnus, Huns, Avars
The Slab Grave culture was essentially Ancient Northeast Asian (ANA,  ), while the neighbouring Sakas combined in almost equal parts Western Eurasian (Sintashta,  ) with Ancient Northeast Asian (Baikal EBA,  ) ancestry, with a smaller Iranian contribution (BMAC,  ).[30]
Genomic evidence from human remains shows that the Avars were essentially derived from Ancient Northeast Asians (ANA).[31]
Nivkh people are closely related to Ancient Northeast Asians.

The Ancient Northeast Asians, particularly the Baikal EBA, contributed to a large extent to the formation of the hybrid Eurasian Tasmola (Central Saka) cultures of Central Asia from around 1,000 BCE, contributing to about half of their genetic profile, highlighting the increase in genetic diversity during the late Bronze Age and the following Iron Age.[30]

The Saka cultures in turn played an important role in the formation of the Xiongnu Empire (3rd century BCE-1st century CE), which combined specific Saka ancestries (particularly Chandman/Uyuk-related ones), with Ancient Northeast Asian-derived Ulaanzuukh and Slab Grave ancestries, to which Sarmatian and Han ancestry was further added at a later stage.[30] High status Xiongnu individuals tended to have less genetic diversity, and their ancestry was essentially derived from the Eastern Eurasian Ulaanzuukh/Slab Grave culture, or alternatively from the Xianbei, suggesting multiple sources for their Eastern ancestry. High Eastern ancestry was more common among high status female samples, while low status male samples tended to be more diverse and having higher Western ancestry.[32] A likely chanyu, a male ruler of the Empire identified by his prestigious tomb, was shown to have had similar ancestry as a high status female in the "western frontiers", deriving about 39.3% Slab Grave genetic ancestry, 51.9% Han ancestry, with the rest (8.8%) being Saka (Chandman) ancestry.[32]

A Hun individual from an elite burial of the mid-4th century CE in Budapest, Hungary, was reconstructed as 60% Ancient Northeast Asian (ANA) and 40% Saka.[33]

The 7-8th century Avars in Europe, particularly as regards the Avar elite, were also confirmed to have essentially Ancient Northeast Asian ancestry (c. 90%), with some additions from other sources.[34]

Göktürks

The Turkic princess Ashina (551–582 CE), whose remains were sequenced, was found to be genetically closely associated with Ancient Northeast Asians (with 97.7% Northeast Asian ancestry, 2.3% West Eurasian ancestry dating back to around 3000 years ago, and no Chinese ("Yellow River") admixture), which according to Yang et al supports a Northeast Asian origin of the Ashina tribe and the Göktürk Khanate.[35] These findings refute "the western Eurasian origin and multiple origin hypotheses" in favor of an East Asian origin for the Göktürks.[36] However, the authors also observed that the population of the "Türkic Empire" as a whole, particularly Central Steppe and Medieval Türks, had a high but variable degree of West Eurasian admixture, suggesting genetic sub-structure within the empire:[37][38] for example, the ancestry of early medieval Turks was derived from Ancient Northeast Asians for about 62,2% of their genome, while the remaining 37,8% was derived from West Eurasians (BMAC and Afanasievo), with the admixture occurring around the year 500 CE.[39][40]

ANA ancestry today

Genetically, ANA ancestry peaks among modern Tungusic, Mongolic and Nivkh-speaking populations of Northeast Asia.[12] ANA ancestry (represented by the Tungusic-speaking Ulchi people) overall forms the main ancestry of the early and contemporary speakers of Turkic, Mongolic and Tungusic languages, which supports their spread from Northeast Asia westwards. An earlier wave into Siberia can be associated with "Neo-Siberians" (represented by Uralic-speaking Nganasans), which may be associated with the spread of Yukaghir and Uralic languages, and the partial displacement of Paleo-Siberians.[41]

"In this genome-wide archaeogenetic study, we find high genetic heterogeneity among late Xiongnu-era individuals at two cemeteries located along the far western frontier of the Xiongnu empire and describe patterns of genetic diversity related to social status. Overall, we find that genetic heterogeneity is highest among lower-status individuals. In particular, the satellite graves surrounding the elite square tombs at TAK show extreme levels of genetic heterogeneity, suggesting that these individuals, who were likely low-ranking retainers, were drawn from diverse parts of the empire. In contrast, the highest-status individuals at the two sites tended to have lower genetic diversity and a high proportion of ancestry deriving from EIA Slab Grave groups, suggesting that these groups may have disproportionately contributed to the ruling elite during the formation of the Xiongnu empire." (...) "a chanyu, or ruler of the empire. Like the elite women at the western frontier, he also had very high eastern Eurasian ancestry (deriving 39.3 and 51.9% from SlabGrave1 and Han_2000BP, respectively, and the rest from Chandman_IA; data file S2C)" (...) "Chandman_IA was representative of people in far western Mongolia associated with Sagly/Uyuk (ca. 500 to 200 BCE), Saka (ca. 900 to 200 BCE), and Pazyryk (ca. 500 to 200 BCE) groups in Siberia and Kazakhstan." (...) "This further suggests the existence of an aristocracy in the Xiongnu empire, that elite status and power was concentrated within specific subsets of the broader population."... Although not conclusive, this suggests that the ANA ancestry source of the Xiongnu-period individuals may not be exclusively traced back to the Slab Grave culture but may also include nearby groups with a similar ANA genetic profile, such as the Xianbei. ... Last, our findings also confirm that the highest-status individuals in this study were females, supporting previous observations that Xiongnu women played an especially prominent role in the expansion and integration of new territories along the empire's frontier.

In the principal component analysis (PCA) (Figs. 1B, S3), the Ashina individual clustered with modern Tungusic and Mongolic speakers, ancient populations from Northeast Asia and eastern Mongolia Plateau, and especially with the Northeast Asian hunter-gatherers previously referred to as "Ancient Northeast Asian" (ANA), that is, DevilsCave_N, Mongolia_N_North, Boisman_MN, AR_EN (Jeong et al., 2020; Ning et al., 2020; Wang et al., 2021), as well as post-Iron Age Eastern Steppe nomadic people including Xianbei, Rouran, Khitan, and part of the Mongol population. (...) In summary, we have unveiled the first genomic profile of theancient Türkic royal family. Our genomic analyses of EmpressAshina revealed Göktürk's Northeast Asian origin (97.7% Northeast Asian ancestry and 2.3% West Eurasian ancestry), refuting the western Eurasian origin and multiple originhypotheses. We found Ashina shared most genetic affinity with post-Iron Age Tungusic and Mongolic Steppe pastoralists,such as Rouran, Xianbei, Khitan, and Heshui_Mohe, and showedgenetic heterogeneity with other ancient Türkic people,suggesting the multiple sources of the Türkic Khanatepopulations. Furthermore, the limited contribution from ancientGöktürk found in modern Turkic-speaking populations onceagain validates a cultural diffusion model over a demic diffusion model for the spread of Turkic languages. (...) Table S2F: "The Ashina showed west Eurasian admixture dating to about 2000 years ago (~1330–1550 years, assuming 29 years/ generation. Mongolia_N_North + Sarmatian/Mongolia_N_North + Afanasievo), while earlyMed_Turk and CentralSteppe_Turk showed more recently mixing date."

  37. Yang 2023, pp. 3–4: "In contrast to Ashina, Central Steppe and early Medieval Türk exhibited a high but variable degree of West Eurasian ancestry, indicating there was a genetic substructure of the Türkic empire."

  39. Jeong et al. 2020, p. 897: See figure 4, B for admixture proportions in earlyMed_Turk. "...it is clear that these individuals have genetic profiles that differ from the preceding Xiongnu period, suggesting new sources of gene flow into Mongolia at this time that displace them along PC3 (Figure 2)...The admixture dates estimated for the ancient Türkic and Uyghur individuals in this study correspond to ca. 500 CE: 8 ± 2 generations before the Türkic individuals and 12 ± 2 generations before the Uyghur individuals (represented by ZAA001 and Olon Dov individuals)."
  40. Yang 2023, p. 4: "The early Medieval Türk (earlyMed_Turk) derived the major ancestry from ANA at a proportion of 62.2%, the remainder from BMAC (10.7%) and Western Steppe Afanasievo nomad (27.1%) (Figs. 1C, 1D; Table S2E)."

S2CID 174809069. Most modern Siberian speakers of Neosiberian languages genetically fall on an East- West cline between Europeans and Early East Asians. Taking Even speakers as representatives, the Neosiberian turnover from the south, which largely replaced Ancient Paleosiberian ancestry, can be associated with the northward spread of Tungusic and probably also Turkic and Mongolic. However, the expansions of Tungusic as well as Turkic and Mongolic are too recent to be associable with the earliest waves of Neosiberian ancestry, dated later than ~11 kya, but discernible in the Baikal region from at least 6 kya onwards. Therefore, this phase of the Neosiberian population turnover must initially have transmitted other languages or language families into Siberia, including possibly Uralic and Yukaghir.
