Genetic characteristics and migration history of a bronze culture population in

[sahaliyan]

Hongjie Li et al.

In order to study the genetic characteristics of the Lower Xiajiadian culture (LXC) population, a main bronze culture branch in northern China dated 4500–3500 years ago, two uniparentally inherited markers, mitochondrial DNA and Y-chromosome single-nucleotide polymorphisms (Y-SNPs), were analyzed on 14 human remains excavated from the Dadianzi site. The 14 sequences, which contained 13 haplotypes, were assigned to 9 haplogroups, and Y-SNP typing of 5 male individuals assigned them to haplogroups N (M231) and O3 (M122). The results indicate that the LXC population mainly included people carrying haplogroups from northern Asia who had lived in this region since the Neolithic period, as well as genetic evidence of immigration from the Central Plain. Later in the Bronze Age, part of the population migrated to the south away from a cooler climate, which ultimately influenced the gene pool in the Central Plain. Thus, climate change is an important factor, which drove the population migration during the Bronze Age in northern China. Based on these results, the local genetic continuity did not seem to be affected by outward migration, although more data are needed especially from other ancient populations to determine the influence of return migration on genetic continuity.

From the paper:

The dominant haplogroup in the Dadianzi people was D4 shared by
five individuals who were associated with four different haplotypes.
The other haplotype belonging to haplogroup D in the Dadianzi population
was designated as D5 by the mutation at site 16 189 (T to C).
The haplogroup M7c included two haplotypes, which were shared by two
individuals in ancient Dadianzi people. The other haplogroups, including
A4, F1b, G1a, M9a, M10 and M8z, were each present in one individual.

Seven male samples were chosen for Y chromosome SNPs among
the 14 individuals. Three samples (S1, S2 and S13) exhibited the
mutations M89C-T, M9C-G, M214T-C and M231G-A, which
were attributed to haplogroup N ( N1C). Two samples (S8 and S12)
exhibited the mutations: M89C-T, M9C-G, M175-5 bp del and
M122T-C, belonging to haplogroup O3 (M122). We failed to obtain
any product from two samples (S5 and S14) (Table 3).

The mtdna of Hongshan culture,same region with Xiajiadian culture(but erlier,in Neolithic time),big differance,the largest haplogroup is N9a,what happened between Hongshan and lower Xiajiadian culture?

То бишь N1c были в Китае уже в бронзовом веке.

М231 - это все-таки только парагруппа N

The full paper,the N is N(XN1c),so dienekes blog is wrong

Thank you very much, sahaliyan, for the article!

Thank you, dear sahaliyan!

The team Jilin university done many anciet DNA reserches,but very few published in English,I think only one paper about Qinghai,and this paper published in English
For example,this is the mtdna from Tuoba Xianbei site

[Nimissin]

My mtDNA: 16223T 16298C 16311C 16327T  - haplogroup C4b.
Compare with ZQ04 and SD11.

I heared the Yakut materal line came from Evenkis,is this true?The most Tuoba Xianbei matches found in northern Tungusic peoples,it's make sense,since the Tuoba Xianbei origined in Hulunbuir
The A of Tuoba Xianbei most likely came from Xiongnu,since even today,the Daurs,Oroqens and Evenks lack A,also haplogroup A is very high in Egyin gol site
