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).
Ancestor - an archaic component, detected in modern African Pygmy populations (such as Mbuties and Biaka) and Khoisan hunter-gatherers.
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 ∼4,500 years ago.
Indian - a component of ancestry harboured by populations of Indian subcontinent
Arctic - a component displayed in genomes of Eskimo Inuits from Greenland and shared with Siberian Chukchis/Koryaks.
Australian - a component of aboriginal ancestry assigned to Australian aborigens.
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.
EastAfrican - a very dilluted component being inherited specififically from ancient inhabitants of Ethiopia and African Horn
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
