NOTE: There will be several images of mummies and dead faces posted here, so if that isn't your cup of tea be aware.
Sorry but not sorry for the snarky 'well ackshually' title gents, but this is a common mistake I see people make. I'll elaborate further below. If by now you haven't heard of the exciting news of the Tarim Mummies, please check out the article right now!
The genomic origins of the Bronze Age Tarim Basin mummies (Click here to read)
Abstract:The identity of the earliest inhabitants of Xinjiang, in the heart of Inner Asia, and the languages that they spoke have long been debated and remain contentious1. Here we present genomic data from 5 individuals dating to around 3000–2800 BC from the Dzungarian Basin and 13 individuals dating to around 2100–1700 BC from the Tarim Basin, representing the earliest yet discovered human remains from North and South Xinjiang, respectively. We find that the Early Bronze Age Dzungarian individuals exhibit a predominantly Afanasievo ancestry with an additional local contribution, and the Early–Middle Bronze Age Tarim individuals contain only a local ancestry. The Tarim individuals from the site of Xiaohe further exhibit strong evidence of milk proteins in their dental calculus, indicating a reliance on dairy pastoralism at the site since its founding. Our results do not support previous hypotheses for the origin of the Tarim mummies, who were argued to be Proto-Tocharian-speaking pastoralists descended from the Afanasievo1,2 or to have originated among the Bactria–Margiana Archaeological Complex3 or Inner Asian Mountain Corridor cultures4. Instead, although Tocharian may have been plausibly introduced to the Dzungarian Basin by Afanasievo migrants during the Early Bronze Age, we find that the earliest Tarim Basin cultures appear to have arisen from a genetically isolated local population that adopted neighbouring pastoralist and agriculturalist practices, which allowed them to settle and thrive along the shifting riverine oases of the Taklamakan Desert.
If you are a bit more in the know however, you might've heard of this as early as August of this year, like I did. And if so this news isn't all that surprising right now, but when you first heard it it was probably incredibly surprising. It sure was for me!
I did expect that prior to Indo-European migration to Xinjiang, there would have been populations similar to those in South Siberia and Central Asia (Botai, Kelteminar, Bolshemys etc) inhabiting this region based on the archaeological records as well as genomic ancestry of the Shirenzigou samples and the maternal haplogroup C4 which has been uncovered in the Tarim and was also found in those populations.
Crazy right? Especially if you have been keeping up with this for a minute, as an article from 2010 claimed that all the paternal haplogroups were R1a-M198, making them good candidates to be lineages dispersed by early Indo-European peoples. But there might be some issues with that.
Before the article was published I was kind of able to figure out that the samples labeled as XH and GMG were from Xiaohe and Gumugou respectively, and that some of the Xiaohe samples overlapped with samples from an earlier study from 2021. Thus I was able to figure out the layers which they were attributed to. I also figured that the Dzungaria_EBA samples were probably just Afanasievo given their location and timeframe, and I was correct regarding that.
The supposed R1a samples came from the oldest layers at Xiaohe, yet these newly published samples from Xiaohe also came from the same layers and one younger, neither showing any signs of Western Steppe Herder ancestry. Their only y-dna haplogroup was R1b-PH155. I think that these R1a calls might be incorrect, or alternatively that the samples were attributed to the incorrect layer but I find that a little less likely.
After the shocking dust settled, it actually dawned onto me how this made things a whole lot clearer. From an archaeological perspective, an Afanasievo > Chemurchek or Abashevo>Sintashta>Andronovo derived origin for these peoples were somewhat strange anyways as there was a very different material culture. But shifts in material cultures are quite common-place so this in itself can be explained away.
One big mystery is why these sites did not contain ceramic pottery, but had these intricate weaved baskets instead. Meanwhile both the Afanasievo and Andronovo had ceramic pottery, as did the Central Asian and Siberian native populations, for thousands of years at that point.These populations were the EHG, EHG/CHG and/or East Asian admixed distant relatives of these Tarim_EMBA populations. Yet there was no pottery at Xiaohe and Gumugou?
The genetic isolated profile might be a clue in this regard. Poterry spread through Siberia during the 6th and 5th millenium b.c, and if these populations separated from their relatives prior to this, they might have missed the mark in regards to this new pottery techniques rapidly spreading through northern Eurasia. Archaeological evidence seems to suggest habitation of the Tarim Basin during that period by foragers, and these may have been the ancestors of the Tarim_EMBA populations as the TMRCA of R1b-PH155 matches up very well with these dates.
Another clue is that there are no real weapons or warrior-esque burials in these sites. Meanwhile these are regularly featured in Afanasievo, Chemurchek and Andronovo sites (and are a big element of Indo-European cultures as a whole), as well across the south Siberian populations with the Seima-Turbino phenomenon. Yet it isn't present amongst the early Tarim cultures.
These two archaeological discrepancies are very easily explained by the genetic ancestry of the populations, which were not genetically derived from Indo-European speaking peoples.
I have to say that I wasn't impressed with their conclusions for the Siberian and Central Asian populations derived from Neolithic West-Siberian related peoples. It seems the authors are unaware of the existence of EHG/CHG related populations such as those uncovered at Progress and Vonyuchka. Or that these populations migrated to the North Caspian region. And that populations such as Steppe Maykop and Kumsay_EBA more or less seem halfway inbetween WSHG and Progress/Vonyuchka (50/50). Thus whenever there is a steppe-like signal required, it gets attributed to either Yamnaya or Dzungaria_EBA.
The Dzungaria_EBA samples, basically just Xinjiang Afanasievo, are quite interesting in my opinion. In the archaeological supplementary it is noted that at one of these sites they uncovered more than a 117 skeletons. They tested a total of 6 samples from 3 sites however.
All in all a very interesting article, with fascinating data. I just wished they also included later samples in their genome-wide analysis, because we know they exist!
So why the title?
I've seen tons of people make statements about "The Tarim Mummies", as they were a set population. They are not. These mummies are a natural phenomenon due to the unique climatic conditions of the Taklamakan desert, which allows for the exceptional preservation of organic materials that we all know of. If I were to die in the desert I could eventually end up as one. Even worse are the inferences made regarding Tocharian speakers, as if we have any evidence that these early mummies were of Tocharian speakers. Or any of the mummies for that matter.
Some of these Tarim mummies date to as early as 1800 b.c, others date to the 4th century A.D, a timespan of two millennia. Several of the famous ones such as Cherchen man and his two wives, or the Subeshi witches are not from the bronze age, but the iron age.
In this study, they have looked at the 1800-1500 b.c mummies of the Xiaohe, Gumugou and Beifang Mudi / Ayala Mazar, the latter name meaning cemetery of women referring to it's high share of female burials, which are grouped in together as part of the same material culture based on the similar traditions, items, clothing, and physical characteristics of the populations.
Speaking of physical characteristics, I'm mostly writing about this ancient DNA article as an excuse to post mummies anyways so here you go:
