the “Ancient North Eurasians” (ANE), represented by the Malta-Buriet samples, are basically a proxy formed from West-Eurasian and East-Eurasian components.
The Ancient North Eurasian (ANE), samplified by the Malta-Buriet samples (MA-1), is a genetic population proxy which formed from ancient West-Eurasian (Paleolithic European) and East-Eurasian (Ancient Eastern Siberian) components. ANE was once widespread in parts of northern Eurasia, mostly in Western Siberia and Eastern Europe, until it got nearly completelly replaced by East Asian-related Paleo-Siberians which themselves again got largely replaced by East Asian Neo-Siberians.
