Lanhai Wei Expansion of Mongolic languages in genetic perspective

Abstract The spread of human languages often were brought along with major demographic expansion. With precise genetic scenario, we may be able to investigate the internal differentiation of a language group at language cluster level. However, little work had been done. In previous works, we had produced a refined phylogenetic tree of paternal lineage of Mongolic-speaking populations, by Y-chromosome sequencing technology. In this study, we conduct a comprehensive comparison between paternal phylogenetic tree and the internal structure of Mongolic language group. The main results are : 1, There are two major demographic admixture events before the foundation of common ancestor group of current Mongolic-speaking populations ; 2, We had identified a paternal lineage as the remains of proto-Mongolic populations, like ancient Xianbei tribes ; 3, The separation of the Dagur language from other languages corresponds to the splitting of downstream of the predominant paternal lineage in Mongolic-speaking populations ; 4, Within the predominant paternal lineage (C2b1b2a-F3796), all samples from Mongolic-speaking populations share a recent common ancestor ; 5, The special status of the Buryat and Moghol languages within Mongolic language group is due to both demographic admixture and language contact. Our research indicates that accurate genetic dating can help us to explore recent differentiations of language groups, as well as to recognize unknown demographic admixture and/or language replacement events in the history. This new powerful approach can be applied to other linguistic groups over the world.

Wen Shaoqing Genetic and linguistic insights into the population admixture and linguistic contact in Northwest China

Abstract : Gansu province located in northwest China, which lies between Mongolian Plateau, Loess Plateau and Tibetan Plateau, was a linguistic, cultural and genetic mixing region for various ethnic groups speaking Sinitic languages and non-Sinitic languages. Within the historical context of east-west intercommunications, present-day populations in this area show a high level of both linguistic and genetic diversity, indicating that their languages and genetic makeup may be associated with complex process of linguistic contact and population admixture. As a result, there are some mixed populations and languages scattering over this area, such as Hui and Dongxiang, Tangwang, Wutun and Gangou, respectively. Nevertheless, little has been known about the origin and formation of the people and their mixed language. In this study, we analyzed about 100 single nucleotide polymorphism and 17 short tandem repeat Y-chromosomal markers in a large sample of 1,525 indigenous individuals from 14 populations in Northwest China to reconstruct the paternal architecture. We also investigated 96 linguistic features from northwestern ethnic groups and other reference populations. Finally, we found different major haplogroup to be prevalent in each population that occupy distinct geographic regions and belong to different linguistic branches. Within haplogroups, a number of haplotype clusters were shown to be specific to various populations and languages. The data suggested that the modern northwestern populations should be an admixture of western and eastern Eurasians during various periods via Silk Road, followed by some extent of isolation, differentiation, and genetic drift in situ. Comparison of genetic and linguistic reconstructions covering the last few millennia showed striking correspondences between the topology and dates of the respective gene and language trees and with documented historical events.
