Lots of ancient Y-DNA from China

Jilin University recently published an ancient DNA study on Chinese Y-chromosomes. It features 119 samples from 13 archaeological sites in northern China. That's quite impressive considering that aDNA is extremely difficult to extract from Y-chromosomes. A paper from 2010 on the Tarim Basin or Xiaohe mummies listed seven R1a1a results, while here we have 11, plus a K*. So it looks like at least some of these are from newly tested Tarim Basin samples.

Niuheliang, Hongshan Culture, 5000 YBP, 4 N, 1 C*, 1 O
Halahaigou, Hongshan-Xiaoheyan Culture, 4500 YBP, all N
Dadianzi, Lower Xiajiadian Culture, 3600 YBP, 3 N, 2 O3
Dashanqian, Upper Xiajiadian Culture, 3000 YBP, 1 C, 3 N1c, 1 N, 2 O3-M117, 2 O3-M324
Jinggouzi, 2500 YBP, all C

Xiaohe, Xinjiang, 3500-4000 YBP, 11 R1a1a, 1 K*
Tianshan Beilu, Hami, Xinjiang, 3300-4000 YBP, 5 N, 1 C
Heigouliang, Xinjiang, 2000 YBP, 6 Q1a*, 4 Q1b, 2 Q
Pengyang, Ningxia, 2500 YBP, all Q1a1-M120
Taojiazhai, Qinghai, 1500 YBP, all O3-M324

Miaozigou, Central-South Inner Mongolia, Yangshao Culture, 5500 YBP, all N
Sanguan site, Yu County, Hebei, Lower Xiajiadian Culture, 3400-3800 YBP, all O3
Hengbei site, Jiang County, Shanxi, 2800-3000 YBP, 9 Q1a1, 2 O2a-M95, 1 N, 4 O3a2-P201, 2 O3, 4 O*

It appears that the chinese scientists are following their politicians footsteps by showing the right side of kashmir and the Arunachal Pradesh as their area! it is a shameful act.

Rui said...

Nirjhar007, I totally agree. What a deplorable thing to do.

Within the 12 Xiaohe graves, there are 11 R1a results, and one K* result. I find this K* result interesting.
I have read the paper of this study. The following is a list of the Y-SNP markers that have been tested in this study:

-C-M216, C-M8, C-M38, C-PK2
-N-M231, N1a-M128, N1b-P43, N1c-Tat
-O-M175, -O1, O2-M95, O3-M122, O3a-M324, O3a3-P201, O3a2c1a-M117 , O3a3c1-M117, O3a-M324, O3a3-P201
-Q-M242, Q-MEH2

As a conclusion from this list of tested markers, the remaining subgroups of the Y-SNP marker K-M9(xN, O, P) have not been tested. I am thinking that this K* result could belong to the Y-SNP haplogroups L or T? Do you guys agree with this? Also, since the combination of subgroups of haplogroups R and T have been found in several unexpected cases in other studies, i think this K* could belong to haplogroup T. Ofcourse in order to prove this, the K* needs to be subtyped.

Yes, the K* could well be T1a2, which has been found in Europe and Xinjiang.

I am going to try to contact professor Hui Zhou from the Jilin University(author of the study paper), and ask if they could subtype this K* result in order to find out if it belongs to T. Do any of you guys know scientists of the Jilin University? Which correct/official e-mail or fax address belongs to the "Research Center for Chinese Frontier Archaeology of Jilin University"? I cannot reach the website of Jilin University.

Just noticed this entry.

Isn't it curious that most sites are dominated by non-O3 lineages such as N and Q and that only a few (Lower Xiajiadian culture, the Qinghai site) are dominated by the most common Chinese lineage today (I mean O3, of course)? There seems to be quite a demographic transition with the change from Honshang to Lower Xiajiadian, which cover more or less the same area of NE China.

Davidski said...

Have you seen this?

What do you make of their estimates for R1a and R1b?

Maju said...

24 Ka?! Not for me, thanks. IMO R1 has been in West Eurasia since at the very least the Gravettian era and may be as old as the Aurignacian.

As I said elsewhere, Q must have diverged from P long before the proto-Amerindian migration began, i.e. most likely Q1 arrived to Altai c. 47 Ka ago already formed. R seems older, so it has a good likelihood of being an Aurignacoid thing, directly related with the first colonization (barring the Arabian OoA journey) of West Eurasia (Neanderlands) by H. sapiens with origins in India (and possibly to some extent also SE Asia).

I'd say that both Q and R1 (with some R* possibly) expanded to West Eurasia at that early age.

I largely used the info provided in this entry, so thanks again for spreading. Feel free to use my maps.

As someone said in the Chinese website. The Jilin university DNA test results are not real, They tried to hide O2b and they didn't find N for political reasons.
