Abstract

The Eurasian Bronze Age (BA) has been described as a period of substantial human migrations, the emergence of pastoralism, horse domestication, and development of metallurgy. This study focuses on individuals associated with BA metallurgical production, specifically the Seima-Turbino (ST) phenomenon (~2,200-1,900 BCE) associated with elaborate metal objects found across Northern Eurasia. The genetic profiles of nine ST51 associated individuals vary widely ranging between ancestries maximized in individuals from the Eastern Siberian Late Neolithic/BA, and those of the Western Steppe Middle Late BA. The genetic heterogeneity observed is consistent with the current understanding of the ST metallurgical network as a transcultural phenomenon. The new data also shed light on the temporal and spatial range of an ancient Siberian genetic ancestry component, which is shared across many Uralic-speaking populations, and which we explore further via demographic modeling using additional genome-wide (2 individuals) and whole genome data (5 individuals, including a ~30x genome) from northwestern Russia.

Elite samples were R1a. Coverage seems to be rather low so likely R1a-Z93+. RO003 was seemingly full Steppe MLBA-like and ROT016 mixed Steppe-MLBA/WSHG-type.

Grave 8, in which RO003 was buried, is particularly rich. It contains two lanceheads of the types KD-10 and KD-14, a socket ax of type K-20, a dagger blade of the type NK-6, several small flint arrowheads, two rectangular flint blades, and a bone handle. 

The inventory of grave 33, in which ROT016 was buried, contains a lancehead of type KD-24, two gold rings, several small flint arrowheads, two stone objects, which are usually described as arrow-smoothers, and a big number of perforated bone battens. These battens are interpreted as the remains of a piece of body-armor.

Archaelogical context for the N-L392  sample. Only this sample seems to have a Kra001 autosomal profile + Uralic-related Y-DNA. Rest of the samples are on a WSHG-cline + some Steppe_MLBA

The individual ROT002 was buried together with a dagger blade of the type NK-4, several nonspecific flint-tools, a grindstone, two ceramic vessels and a bone-arrowhead, similar to arrowheads, which were found among the ST-materials of the Kaminskaya Cave on the western site of the Urals.

G25 coordinates for this study?

Are there coordinates out yet ?

This publication is with Johannes Krause and Wolfgang Haak. Why they don't publish the data in advance ? We can't do anything without DNA shared data, will wait for the official publication.

[TanTin]

I don't know there is lot of music shared in this topic, so I will share some:

... and still waiting for the official publication and DNA data for this preprint.

This Yakutia ancestry is also associated with Yukaghiric, Turkic, Mongolic, and Tungusic speakers.

Data Availability. Genomic data (BAM and fastq formats) are available on the European
646 Nucleotide Archive (ENA) under accession number PRJEBXXX, genotypes in eigenstrat
647 format can be found at https://edmond.mpdl.mpg.de.

The data for this study should be also available in eigenstrat format , but I don't find option to download it.
There is some Jupyter Notebook - 581.9 KB  file only.

The data from this study should be very interesting, because we have far East Asians ,  Europeans and Scandinavians as part of the same culture (archeology).

nitpicking: Seima-Turbino, at least in Russian literature, is usually not considered as a coherent culture, but rather as trans-cultural phenomenon. That is Seima Turbino type of weapons are found in areas occupied by different cultures.

I really and really want to know the different culture.

Seima turbino culture ( or phenomenon ) is extremely important, which has a clue to solve PIE:

Most of the samples in this paper have low coverage, fortunately some of them were also sequenced to higher coverage by Harvard (upcoming Zeng et al. paper), so we'll have to wait for those BAMs to get more detailed subclades. ROS002 is just N-L1026, and it should be at least N-Z1936 according to Zeng preprint, while I couldn't find anything derived below R1a-M417 in ROS003.
