"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 ST-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."

Y-chromosome haplogroups.
"We performed Y-haplogroup (Y-hg) typing of the ROT malesusing the YMCA method19 388 (Table 1). We identified two individuals that carried the R1a Y-hg389 (ROT003 (R1a-M417) and ROT016 (R1a-Z645)), one of the most widely distributed Y-hgs inEurasia40 390 . However, both individuals could be R1a-Z645, since ROT003 does not have either391 ancestral or derived ISOGG list SNPs after R1a-M417.
ROT002, the individual with the highest proportion of north Siberian ancestry, was assigned to399 the N1a1a1a1a (N-L392) haplogroup.
Another individual407 (ROT017) was determined to belong to the Q1b1 (Q-L53) haplogroup, which is common408 among present-day Turkic speakers across Eurasia. The branch Q-YP4004 includes Central409 Asian Q-L53(xL54) lineages and one ancient Native American individual from Lovelock Cavein Nevada dated 1.8 ky47 410 , and the oldest individual with this haplogroup is irk040 (Cis-BaikalNeolithic, 4846 BP)28 411 . The lineage C2a-L1373, carried by ROT011, is found at high frequency412 in Central Asian populations, North Asia and the Americas. C2a-L1373 expanded to North Asiaand the Americas post-LGM, around 17,700–14,300 years ago48 413 .
Lastly, haplogroup R1b1a1a414 (R1b-M73), a sister-clade of R1b-M269, is carried by ROT006."
