In archaeogenetics, the term Ancient Northern East Asian (ANEA), also known as Northern East Asian (NEA), is used to summarize the related ancestral components that represent the Ancient Northern East Asian peoples, extending from the Baikal region to the Yellow River and the Qinling-Huaihe Line in present-day central China.[1][3] They are inferred to have diverged from Ancient Southern East Asians (ASEA) around 20,000 to 26,000 BCE.[1][4][5][6]
The ANEA can be differentiated into broadly three sub-groups, namely the “Ancient Northeast Asians“ (ANA), “Neo-Siberians", and "Yellow River farmers". The ANEA are to be distinguished from the namely similar "Ancient Northeast Asian" (ANA) lineage, which is alternatively also known as "Amur ancestry", and which forms a sub-group of the ANEA grouping, specifically ancestral to hunter-gatherer people of the 7th-4th millennia before present, in the Amur region and later expanding to far-eastern Siberia, Mongolia and the Baikal regions, but which are most closely related to other ancient northern East Asians, such as the earlier expanding "Neo-Siberians" evident in the Early Neolithic Baikal region.[2][7]
The "Neo-Siberians," or "inland Northeast Asians" (including Yumin hunter-gatherers and Transbaikal_EMN ancestry), are associated with an inland expansion route of Ancient Northern East Asians around 14,000 years ago. They can be distinguished from the "Amur hunter-gatherers" (7,000–14,000 years ago), who carry Ancient Northeast Asian (ANA) ancestry. The Neo-Siberians contributed mainly to Neolithic and Bronze Age populations in the Baikal region, such as the Neolithic Baikal hunter-gatherers of the Kitoi culture (5,200–4,200 BCE), Late Neolithic/Bronze Age Yakutia, and Krasnoyarsk groups of Eastern Siberia and the Altai-Sayan region. They may be linked to the early spread of Proto-Uralic speakers and, in conjunction with Ancient Paleo-Siberians, to Bronze Age Western Baikal hunter-gatherers of the Glazkovo culture (around 2,500 BCE), associated with early Yeniseian speakers.[9][10][11][12]
Ancient Northeast Asians (Amur ancestry), represented by Mesolithic Amur specimens (c. 7-14kya) and subsequent samples from Mongolia, expanded after the dispersal of "Neo-Siberian" like groups, and may be associated with the spread of Turkic, Mongolic, and Tungusic speakers.[9][11]

PMID31168093. S2CID174809069. 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.
