[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.
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.
[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.
