Mitochondrial DNA diversity in the gene pool of the Neolithic and Early Bronze Age Cisbaikalian human population

Abstract

This paper presents the results of a study of a mitochondrial DNA sample (N = 15) from the remains of representatives of the Neolithic and Early Bronze Age (VI–III millennia BC) Cisbaikalian human population. It was found that the mitochondrial gene pool of the ancient population under study contains lineages of East Eurasian haplogroups D, G2a C, Z, and F1b. The results of the comparative analysis of the group under study with ancient and modern Eurasian populations suggest that the development of autochtonous East Eurasian genetic components was the main mechanism of the formation of the population of the Baikal region. Genetic contacts with populations of neighboring regions of Central Asia also contributed to the formation of the gene pool of the Cisbaikalian population.
