In archaeogenetics, the term Eastern Hunter-Gatherer (EHG), sometimes East European Hunter-Gatherer, or Eastern European Hunter-Gatherer) is the name given to a distinct ancestral component that represents descent from Mesolithic hunter-gatherers of Eastern Europe.[1] During the Mesolithic, the EHGs inhabited an area stretching from the Baltic Sea to the Urals and downwards to the Pontic–Caspian steppe.[2]
