Quote:
NorthEastEuropean - a fancy moniker for a dominant type of ancestry in North-Eastern Europe based on older type of ancestry (WHG, west European Hunter-Gatherer), today this type of ancestry peaks in the Baltic region and Scandinavia
Neolithic - a component, modeled on genomes of first neolithic farmers of Anatolia (West Asia), these farmers from West Asia migrated to Europe during the Neolithic and carried this component with them.
Caucasian - a major component of ancestry of modern inhabitants of Caucasus, Iran and northern Indian : it was derived from genomes of mesolithic Caucasian Hunter-gatherers: a major ancestral component linked to CHG was carried west and east by migrating herders from the Eurasian Steppe.
Steppe - a component which was sourced from ancient genome of European Bronze Age pastoralists: it roughly approximates levels of ancient North Eurasian hunter-gatherers' heritage, which was subsequently shown to have an influence in later eastern hunter-gatherers and to have spread into Europe via an incursion of Steppe herders beginning around 4,500 years ago.
NearEast - a component harboured and later carried by ancient populations of Near East, in our time it reaches the maximum among Bedoins and Saudi Arabians; the component seems to carry an excess of Eurasian Basal component relative to Neolithic component.
Amerindian - a component, which is modal (i.e has a peak) in various native American groups of North and South America, as well as in ancient DNA of Native Americans (Clovis, Kennewick man, etc).
EastAfrican - a very dilluted component being inherited specififically from ancient inhabitants of Ethiopia and African Horn
