Mitochondrial deoxyribonucleic acid (mtDNA) polymorphisms were examined in bone samples of individuals buried in an early Neolithic (c. 5800–4900 BCE) hunter-gatherer cemetery, Shamanka II, located at the southwestern tip of Lake Baikal, Siberia. The main objective was to compare the mtDNA polymorphisms observed at Shamanka II to those previously reported from the Lokomotiv (early Neolithic) and Ust’-Ida (Bronze Age) cemeteries in the same general region also known as the Cis-Baikal. All three cemetery populations comprised remains containing mtDNA haplogroups characterized as being of Asian origin (haplogroups A, C, D, F, G2a, and U5a). The results confirmed that haplogroup frequency distributions among Neolithic populations in southern Siberia were similar, and differed significantly from haplogroup frequency distributions among the Bronze Age populations.
