From this, we could plot the distribution of the average ancestry components across Eurasia and within Britain. From top left clockwise: Neolithic farmer, Steppe/Yamnaya, Western H-G, Eastern H-G, Caucasus H-G.
EHG-related ancestry is highest in Mongolia, Finland, Estonia and Central Asia.
CHG-related ancestry is maximised in countries east of the Caucasus, in Pakistan, India, Afghanistan and Iran, likely reflecting both Caucasus hunter-gatherer and Iranian Neolithic signals, explaining the relatively high levels in south Asia.
Neolithic farmer ancestry is concentrated around the Mediterranean basin, with high levels in southern Europe, the Near East, and North Africa, including the Horn of Africa.
