Description
Haplogroup G is strongly associated with Caucasian populations — particularly Georgians, Armenians, and Ossetes — and with Neolithic farmers who carried agriculture from Anatolia into Europe. The subclade G2a was the dominant haplogroup of early European Neolithic farmers, and ancient DNA studies have confirmed its presence across Neolithic sites in Central Europe, France, and Iberia. G2a was subsequently diluted by incoming Yamnaya steppe pastoralists and later Bronze Age migrations, but survives today at highest frequencies in the South Caucasus and isolated refugia such as Sardinia. Famous ancient carriers include the Tyrolean Iceman Ötzi (~3300 BCE) and numerous Neolithic farmers from France, Hungary, and Germany.
Interesting Fact
Ötzi the Iceman — a 5,300-year-old mummy discovered in the Alps — belongs to haplogroup G2a2b, and his closest modern relatives are found among Sardinians and Corsicans, populations that preserved Neolithic farmer ancestry relatively undiluted by later Bronze Age steppe migrations.
