My K12 results and populations


West European Farmers (4000-5000 years)  25.2%  References include Neolithic genomes from Portugal, and Chalcolithic genomes from Spain. The similarity between these farmers and other Mediterranean farmers points to a rapid spread of agriculture in Europe around 7000 years ago.

East European Farmers (5000-8000 years)  22.9%  References consist of genomes from Turkey, Greece, and other parts of SE Europe from the Neolithic period. These represent descendants of the first farmers to colonize Europe from the Near East.

Neolithic-Chalcolithic Iran-CHG (5000-12000 years)  6.7%  Based on Neolithic and chalcolithic period samples recovered from Northwest Iran. The farmers from the Zagros mountain Iran region descended from one of multiple, genetically differentiated hunter-gatherer populations in southwestern Asia.  They are estimated to have separated from Early Neolithic farmers in Anatolia some 46,000 to 77,000 years ago, and show affinities to modern-day Kurd, Iranian, Pakistani and Afghan populations.  The Neolithic Iranian references used for this component, were recovered from the Kurdistan region of Iran, and appear to be around 9000 years old. The Chalcolithic Iranian references have been dated to around 5000 years old. The Caucasus Hunter Gatherers (CHG) appear to have genetically contributed to present day Europeans, W Asians, and S Asians.

Levant (4000-8000 years)  4.1%  Based on neolithic and bronze-age period samples recovered from the Levant area in the Middle-East. The references for the bronze age Levant farmer (BA) samples were recovered from the Ain Ghazal, Jordan area and were dated to about 4300 years ago.  The first farmers of the southern Levant (Israel and Jordan) and Zagros Mountains (Iran) were strongly genetically differentiated, and each descended from local hunter-gatherers. By the time of the Bronze Age, these two populations and Anatolian-related farmers had mixed with each other and with the hunter- gatherers of Europe to drastically reduce genetic differentiation. The impact of the Near Eastern farmers extended beyond the Near East: farmers related to those of Anatolia spread westward into Europe; farmers related to those of the Levant spread southward into East Africa; farmers related to those from Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of he Eurasian steppe spread eastward into South Asia.


Andronovo-Srubnaya (3000-4000 years)  14.3%  The Andronovo culture, which are believed to have aided in the spread of Indo_European languages, is a collection of similar local Bronze Age cultures that flourished around 3000-4000 years ago in western Siberia and the west Asiatic steppe. This culture overlapped with the Srubna culture in the Volga-Ural region of Russia.

Yamnaya-Afanasievo-Poltavka (4000-5000 years)  10.1%  Believed to be among the first Indo-European language speakers. The Yamnaya genetically appear to be a fusion between the Eastern European Hunter Gatherers that inhabited the western Siberian steppe, and a populations from the Caucasus region. Descendants of the Yamnaya would later change the genetic substructure of indigenous Neolithic Europeans via invasions of Europe from the Eurasian steppe.

Karasuk-E Scythian (2000-3000 years)  6.4%  This cluster is based on ancient genomes from the Karasuk culture, supplemented with two Iron-Age Eastern Scythian samples. The Karasuk percentage should be interpreted as a diffusion of DNA from the Eastern Eurasian Steppe populations post Bronze Age, via Turkic expansions, as well as more subtle diffusions via NE Caucasus populations.


These were the indiginous populations of Europe that substantially contributed to the genetics of modern Europeans. It is believed that these hunter gatherers arrived in Europe around 45000 years ago from the Near East.


Eastern Non Africans are one of the earliest splits from humans that migrated out of Africa to the Near East around 100,000 years ago. It is believed that ENAs split from the population in the Near East around 50,000 years ago. Populations such as Papuans and Aboriginal Australians are modern descendants of ENAs. The ENA component here is based on Papuan and Aboriginal Australian references.
