The Sogdians in China II

The comments on "Gene Expression" give some more information. My own:





















And the very informed comment by John J. Emerson, a specialist in Chinese history:

The Sogdians in China

National Geographic has a new article about the genetical studies concerning the Sogdian leader Yu Hong in a Tang-chinese grave. (Studium generale)

Yu Hong was a "Sogdian". Dienekes had some links to the New York Metropolitan Museum of Art, which had more information about this people and about this grave.

I have made some studies about the Sogdians in the last weeks. (Studium generale) The Sogdians came mostly from Samarkand and the rich and economically whealthy "Sogdiana". Roxana, the first wife of Alexander the Great was a sogdian princess. The Sogdians were mostly rich traders (caravaniers) between Korea and Byzanz. And they made a lot of politics in this area. They had communities in the Tarim-area and far beyond.

In the chinese art of the Tang area often you can find pieces that shows "Foreigners", "Westerners". Mostly they were Sogdians. Often they are shown as comedians, dancers, musicians. They made several religions spread in East Asia (Buddhism, Manichaeism and others).

In China they have now found several graves of Sogdian leaders. Often they were mandarin's and had high positions in the chinese administration.

Over on my german blog I have more information (and some pictures and english links) about them. (Studium generale) And "Gene Expression" has something.

Beginning of agriculture in China by migrations from Europe?

Last year in the journal "Archäologie in Deutschland" there were given hints by Detlef Gronenborn (pdf., german language), that archaeological connections exist between the first european farmers (the Linearbandkeramiker) and new detected archaeological cultures in Russia (Elshan-Culture) and Northern China. (More from Detlef Gronenborn here - also in English.)

Now it seems that we have ancient genetic data for this connections as well. And that would mean, that these connections were'nt only cultural but also genetic. This would be a very great surprise.
The Phylogeography of Haplogroup N1a

Gokcumen O et al.

Recent studies have revealed a complex geographic distribution of haplogroup N1a. This rare and distinctive lineage is widely distributed across Eurasia and Africa, but always found at very low frequencies. However, despite its rarity, the genetic diversity within N1a has remained relatively high (h=0.9605). The reduced median network of N1a haplotypes not only reflects this level of diversity, but also exhibits several relatively well-defined branches. The distribution of N1a is intriguing because of revealing previously unrecognized connections between populations. What makes N1a even more interesting is the prevalence of this lineage in ancient European populations. Haak et al. (2005) found that 25% of their European Neolithic samples belonged to N1a and dated to ~5000 BCE, whereas the frequency of this lineage in contemporary Europeans is only ~0.2%. In addition, an Iron Age skeleton from Kazakhstan had an N1a haplotype, suggesting the existence of this lineage in the Altai Republic in ~500BCE (Ricaut et al. 2004). Indeed, we found several haplogroup N1a mtDNAs in indigenous Altaians and Altaian Kazakhs. To further elucidate the phylogeography of this lineage in Central Asia, we sequenced the whole mtDNA genomes of our N1a haplotypes, and analyzed the resulting data with several quantitative methods and simulation programs to estimate their expansion times and spatial distribution in Eurasia. Our findings suggest that there are two well-defined sublineages within N1a, and that the dispersal of this haplogroup could be associated with the Neolithic expansion and with prehistoric interactions between Central Asian and European populations.

Barley domesticated in China 7000 BC

Barley seems to be domesticated in Northern China also. And that's different to wheat, that is domesticated only in the Fertile Crescent:

Over the past decades, archaeologists have unearthed the earliest remains of domesticated barley at sites in the Fertile Crescent that date back 10,500 years. But there is also evidence for barley cultivation about 9000 years ago at sites further east in Central Asia. (...)
Evolutionary biologists Peter Morrell and Michael Clegg (...) sequenced genes of wild and domesticated barley from the two regions. (..) Morrell and Clegg conclude that barley was domesticated at least twice, first in the Fertile Crescent and then between 1500 to 3000 kilometers further east in Central Asia. (...)

Europeans in China (220 BC)

From time to time we receive new facts about european genetical influences in China, most probably mediated by the Tocharians living from 2000 BC to 400 AD in the Talimakan desert at the north-western border of China. Evidenced by hundreds of mummies in Urumchi museum. But a lot of other european-derived populations also existed in the eurasian steppe around the boarders of China.

In summer last year "Archaeology" magazine had an interview with Victor Mair, one of the specialists concerning european influences in bronze age China, where new facts were mentioned (not very precise - but you have to take what you can get).

Are new DNA findings a surprise or just one more piece of evidence for China's early connections?

According to a news report from China, DNA analysis indicates that at least one of the workers who constructed the tomb of Qinshihuang, the first emperor of China, was in fact of west Eurasian ancestry. ARCHAEOLOGY talked to the University of Pennsylvania's Victor Mair about this announcement and its implications for understanding ancient connections between China and the West. (...)

DNA analysis from archaeological remains can be very tricky. What can you tell us about the researchers involved with this case?

For the present time, I will say this about the genetics research that forms the basis of the recent announcement. First of all, it was done in the very best population genetics lab in China, that of Prof. Jin Li at Fudan. This is a state of the art facility. I have visited it several times, and I can attest that the equipment and skills of the researchers there are at a world standard. I know Xu Zhi and Tan Jingze, both of whom were quoted in the reports. These are careful, serious scientists. Incidentally, early DNA specialists from Jilin University in northeast China are also working on the Tarim Basin mummies at the moment. I have visited that lab too, and I am certain that it will be the source of equally remarkable news before long.

Was just this one set of remains tested?

Of the 121 shattered skeletons, 15 were tested, but so far only one of them appears to have a west Eurasian genetic profile. It is said that his genetic features mark him as belonging to T-genodeme, which unmistakably belongs to a western haplotype. Specifically, Chinese geneticists say that this links him with people living to the west of the Pamirs: the Parsi (Persians) in India and Pakistan, the Kurds in Turkmenistan, and the Persians in Iran.
