Almost everything you ever wanted to know about the Xiaohe-Gumugou cemeteries

I’m reading an interesting and very comprehensive new archeological thesis about the Tarim Basin mummies. It’s freely available via Uppsala University’s DiVA portal here:

Shifting Memories: Burial Practices and Cultural Interaction in Bronze Age China: A study of the Xiaohe-Gumugou cemeteries in the Tarim Basin

The author, Yunyun Yang, has some suggestions for the future direction of research on the topic:

1. Analysis of Y chromosomal DNA on the males from 4th-1st layers of the Xiaohe cemetery: it is not clear if they were genetically distinct from the Afanasievo (and Yamnaya) males, and consistent to the Andronovo males.
2. More research on ancient DNA of the six males buried in type I the sun-radiating-spokes graves: the six males were so different in the Gumugou cemetery, and we don’t know who they were. In this study, it has been suggested that they came from the parallel Andronovo horizon, and preserved some of their original social identities.
3. Analysis of the white sticky materials painted on the dead’s hair, faces, and bodies: it is not clear what this material is. It might be application of dairy/milk products with some holy functions. And the interesting point is why the dead was painted on such materials, for holy reasons, and/or was embalmed that way for preventing decay of the dead bodies?
4. Research on the use of Ephedra plants: Ephedra twigs were common and important in both cemeteries. Were they related to the “Soma” in ancient India (Vedas) and/or “Haoma” in ancient Iran (Avesta)? Were the Ephedra twigs related to the body painting (whitish sticky materials painting on skins of the dead)? Was there a common use of Ephedra plant in more nomadic groups in the Eurasian Steppe?
5. Research on the comparisons between the Andronovo burials and the stone circular-kerbs with stone-pits in Xinjiang: a major obstacle to such research is the language barriers, with the material published in English, Chinese and Russian. Such research is, however, essential to understand the conjunction of the geographical areas, the expansion of nomadic groups, the spreading of horses and wagons (linked to the noble groups of the Shang Dynasty (1600-1046 BCE) in central China), the formation of the Silk Road in this area (till the expansion of Han Dynasty (206 BCE-220 CE)), the moving of Indo-Iranians, the expansion of Scythians (900 BCE-400 CE), etc.

I agree, but I’d also add that we need a good number of ancient Y-chromosome and genome-wide samples from across space and time in the Tarim Basin, including and especially from attested Tocharian-speaking communities. That’s really the only way to figure out whether the Tarim Basin mummies belonged to the speakers of Indo-Iranian or Tocharian languages, and whether the latter were introduced into the region by migrants from the Afanasievo culture.
