Ancient Northeast Asian
In archaeogenetics, the term Ancient Northeast Asian (ANA), also known as Amur ancestry, 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, 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).
ANA ancestry is represented by hunter-gatherer remains from the Amur region, as well as remains found in present-day Mongolia.
