Chechens
Chechens (; '; Old Chechen: Нахчой "Naxçoy") are a Northeast Caucasian ethnic group of the Nakh peoples originating in the North Caucasus region of Eastern Europe. They refer to themselves as Vainakhs (which means "our people" in Chechen) or Nokhchiy (pronounced ; singular Nokhchi, Nakhchuo or Nakhtche). Chechen and Ingush peoples are collectively known as the Vainakh. The majority of Chechens today live in the Chechen Republic, a subdivision of the Russian Federation.
Chechens
A 2004 study of the mtDNA showed Chechens to be extremely diverse in the mitochondrial genome, with 18 different haplogroups out of only 23 samples. Chechens clustered closest to Azeris, Georgians and Kabardins. They clustered closer to European populations than Middle Eastern populations this time, but were closer to Western European populations (Basques and Britons) than to Eastern European populations (Russians and other Slavs, as well as Estonians), despite living in the East. They actually clustered about as close to Basques as they did to Ingush (Chechens also cluster closer to many other populations than Ingush, such as Abazins), but the Chechens were the closer to the Ingush than any other population, the imbalance probably largely being due to the uniqueness of the Ingush on the mitochondrial DNA among those tested.
