Chinese research on Xinjiang mummies seen as promoting revisionist history
A new Chinese study on the ancient populations of Xinjiang purports to show modern-day residents descend from a mix of ethnicities, but scientists and experts on the region cautioned the findings are being used to support China’s forced assimilation policy toward the predominately Muslim Uyghurs. The study from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences is based on 201 ancient human genomes from 39 different archeological sites in the Xinjiang Uyghur Autonomous Region (XUAR). Scientists analyzed the genetic composition, migration and formation of the ancient inhabitants of Xinjiang during the Bronze Age, which lasted from 5,000 to 3,000 years ago, the Iron Age, which lasted between 3,000 and 2,000 years ago, and into the Historical Era, which started about 2,000 years ago. They published their findings in the April edition of the journal Science in an article titled “Bronze and Iron Age population movements underlie Xinjiang population history.” The report states that the region’s ancestral population during the Bronze Age was linked to four different major ancestries — those of the Tarim Basin, which includes present-day Xinjian; Central Asia; and the Central and Eastern Eurasian Steppes. “Archaeological and mitochondrial studies have suggested that the BA [Bronze Age] inhabitants and cultures of Xinjiang were not derived from any indigenous Neolithic substrate but rather from a mix of West and East Eurasian people, whereas BA burial traditions suggest links with both North Eurasian Steppe cultures and the Central Asian BMAC civilization,” the report says, referring to the Central Asian Bactria-Margiana Archaeological Complex (BMAC) in the south. Further mixtures between Middle and Late Bronze Age Steppe cultures continued during the late Bronze and Iron Ages, along with an inflow of East and Central Asian ancestry, the report says. “Historical era populations show similar admixed and diverse ancestries as those of present-day Xinjiang populations,” the report says. “These results document the influence that East and West Eurasian populations have had over time in the different regions of Xinjiang.” The study by the Chinese Academy of Sciences comes at a time when the Chinese government has stepped up its assimilation of the predominantly Muslim Uyghurs to inculcate a common identity among Uyghurs with other ethnicities in the country. The government rejects claims that the ethnic minority group has its own history, culture, language and way of life.

The XUAR’s Communist Party Committee set a political goal for archaeological research aimed at combating “separatism” and emphasized that cultural relics should serve the concept that Xinjiang has always been an inseparable part of China. On March 22, 2017, then-Party Secretary Chen Quanguo said at an archaeological work conference that “archaeological work is necessary in establishing and advancing socialist values in Xinjiang, in deepening patriotic education, and in the fight against separatist ideas.” But an expert in the genetics of ancient Central Asian populations based in the United States says the report’s findings do not significantly differ from findings on the Bronze Age published recently by a group of international researchers. Vagheesh Narasimhan, an assistant professor in the Department of Integrative Biology and the Department of Statistics and Data Sciences at the University of Texas at Austin, told RFA that the findings in the Science article are similar to those published late last year by international researchers. “A few months ago there was a report of the sequencing of certain mummies from the Tarim Basin from the Bronze Age,” he said. “In this paper [from April 1], they also added 200 genomes from various time periods from all over Xinjiang. They co-analyzed the data from the previous analysis with the analysis in this paper, and they tried to draw conclusions combining the data from the previous paper by the international team with data from this group.” Narasimhan said that the two studies found a similar genetic ancestry in Xinjiang from the Bronze Age. But he said the findings do not refute the idea that Uyghurs are a distinct ethnicity. “You can’t think two groups are the same just because they have a common ancestry; in that case, every person in the world would have a common ancestry from Africa,” he said. “We have to think carefully about which population they’re actually using as a reference.” In its analysis of the Iron Age population of Xinjiang, the Science article stresses that iron materials found during this era were related to the Saks, or the Scythians, an important nomadic culture at the time. It also notes that many archaeological finds connected to the group have been found in Xinjiang’s Ili River Valley and Tarim Basin, and that a diverse conglomeration of many nomadic tribes, including the Saks, Huns, Paziriks and Taghars, appeared around the region. The Science article also states that from among these groups, the Saks were the descendants of the Andronova, Srubnaya, and Sintashta peoples from the latter periods of the Bronze Age and that the other ancestors of the Saks are connected to the populations of the Bayqal Shamanka and Bactria-Margiana and are related to the language of Hotan, which was part of the Indo-European family. But about 2,200 years prior, the region had become a point of conflict between the Yuezhi (Yawchi or Yurchi), Huns, Hans and Turks. “Thus, Xinjiang represents a key area for studying the past confluence and coexistence of populations with dynamic cultural, linguistic and genetic backgrounds,” the report says.
