The Yamna culture (Ukrainian: Ямна культура, Russian: Ямная культура, "Pit [Grave] Culture", from Russian/Ukrainian яма, "pit") is a late copper age/early Bronze Age culture of the Southern Bug/Dniester/Ural region (the Pontic steppe), dating to the 36th–23rd centuries BC. The name also appears in English as Pit Grave Culture or Ochre Grave Culture.
Characteristic for the culture are the inhumations in kurgans (tumuli) in pit graves with the dead body placed in a supine position with bent knees. The bodies were covered in ochre. Multiple graves have been found in these kurgans, often as later insertions.
Spread and identity
The Yamna culture is identified with the late Proto-Indo-Europeans (PIE) in the Kurgan hypothesis of Marija Gimbutas. It is the strongest candidate for the Urheimat (homeland) of the Proto-Indo-European language, along with the preceding Sredny Stog culture, now that archaeological evidence of the culture and its migrations has been closely tied to the evidence from linguistics.
Pavel Dolukhanov argues that the emergence of the Pit-Grave culture represents a social development of various local Bronze Age cultures, representing "an expression of social stratification and the emergence of chiefdom-type nomadic social structures", which in turn intensified inter-group contacts between essentially heterogeneous social groups.
It is said to have originated in the middle Volga based Khvalynsk culture and the middle Dnieper based Sredny Stog culture. In its western range, it is succeeded by the Catacomb culture; in the east, by the Poltavka culture and the Srubna culture.
DNA from the remains of nine individuals associated with the Yamna culture from Samara Oblast and Orenburg Oblast has been analyzed. The remains have been dated to 2700-3339 BCE. Y-chromosome sequencing revealed that one of the individuals belonged to haplogroup R1b1-P25 (the subclade could not be determined), one individual belonged to haplogroup R1b1a2a-L23 (and to neither the Z2103 nor the L51 subclades), and five individuals belonged to R1b1a2a2-Z2103. The individuals belonged to mtDNA haplogroups U4a1, W6, H13a1a1a, T2c1a2, U5a1a1, H2b, W3a1a and H6a1b. A recent genome wide study revealed that autosomal DNA characteristics are very close to the Corded Ware culture and estimated a 73% ancestral contribution from the Yamna into the Corded Ware. The same study estimated a 45-50% ancestral contribution of the Yamna into modern Central & Northern Europeans, and a 20-30% contribution into modern Southern Europeans [excluding Sardinians]. The above information makes it quite clear that Haplogroup R1b (Y-DNA) is far from being aboriginal to western Europe as previously thought.
