Ancient North Eurasian

In archaeogenetics, the term Ancient North Eurasian (ANE) is the name given to an ancestral component that represents the lineage of the people of the Mal'ta–Buret' culture (c. 24,000 BP) and populations closely related to them, such as the Upper Paleolithic individuals from Afontova Gora in Siberia. Genetic studies also revealed that the ANE are closely related to the remains of the preceding Yana Culture (c. 32,000 BP), which were dubbed as 'Ancient North Siberians' (ANS), and which either are directly ancestral to the ANE, or both being closely related sister lineages, sharing a common origin from the merger of an 'Early West Eurasian' hunter-gatherer lineage (represented by Kostenki-14, c. 38,000 BP) and an 'Early East Eurasian' population (represented by the Tianyuan man, c. 40,000 BP). The Ancient North Eurasians derive around 2/3 from an Early West Eurasian lineage and around 1/3 of their ancestry from an Early East Eurasian lineage.

Around 20,000 to 25,000 years ago, a branch of Ancient North Eurasian people mixed with Ancient East Asians, which led to the emergence of Ancestral Native American, Ancient Beringian and Ancient Paleo-Siberian populations. It is unknown exactly where this population admixture took place, and two opposing theories have put forth different migratory scenarios that united the Ancient North Eurasians with ancient East Asian populations.

ANE ancestry has spread throughout Eurasia and the Americas in various migrations since the Upper Paleolithic, and more than half of the world's population today derives between 5 and 42% of their genomes from the Ancient North Eurasians. Significant ANE ancestry can be found in Native Americans, as well as in regions of northern Europe, South Asia, Central Asia, and Siberia. It has been suggested that their mythology may have featured narratives shared by both Indo-European and some Native American cultures, such as the existence of a metaphysical world tree and a fable in which a dog guards the path to the afterlife.
