Western Steppe Herders (original) (raw)

dbo:abstract

In archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Eneolithic steppe around the turn of the 5th millennium BCE, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary European and South Asian populations. This ancestry is often referred to as Yamnaya Ancestry, Yamnaya-Related Ancestry, Steppe Ancestry or Steppe-Related Ancestry. Western Steppe Herders are considered descended from Eastern Hunter-Gatherers (EHGs) who reproduced with Caucasus Hunter-Gatherers (CHGs), and the WSH component is analysed as an admixture of EHG and CHG ancestral components in roughly equal proportions, with the majority of the Y-DNA haplogroup contribution from EHG males. The Y-DNA haplogroups of Western Steppe Herder males are not uniform, with the Yamnaya culture individuals mainly belonging to R1b-Z2103 with a minority of I2a2, the earlier Khvalynsk culture also with mainly R1b but also some R1a, Q1a, J, and I2a2, and the later, high WSH ancestry Corded Ware culture individuals mainly belonging to haplogroup R1b in the earliest samples, with R1a-M417 becoming predominant over time. Around 3,000 BC, people of the Yamnaya culture or a closely related group, who had high levels of WSH ancestry with some 10-18% Early European Farmer (EEF) admixture, embarked on a massive expansion throughout Eurasia, which is considered to be associated with the dispersal of at least some of the Indo-European languages by most contemporary linguists, archaeologists, and geneticists. WSH ancestry from this period is often referred to as Steppe Early and Middle Bronze Age (Steppe EMBA) ancestry. This migration is linked to the origin of both the Corded Ware culture, whose members were of about 75% WSH ancestry, and the Bell Beaker ("Eastern group"), who were around 50% WSH ancestry, though the exact relationships between these groups remains uncertain. The expansion of WSHs resulted in the virtual disappearance of the Y-DNA of Early European Farmers (EEFs) from the European gene pool, significantly altering the cultural and genetic landscape of Europe. During the Bronze Age, Corded Ware people with admixture from Central Europe remigrated onto the steppe, forming the Sintashta culture and a type of WSH ancestry often referred to as Steppe Middle and Late Bronze Age (Steppe MLBA) or Sintashta-Related ancestry. Through the Andronovo culture and Srubnaya culture, Steppe MLBA was carried into Central Asia and South Asia along with Indo-Iranian languages, leaving a long-lasting cultural and genetic legacy. The modern population of Europe can largely be modeled as a mixture of WHG (Western Hunter-Gatherer), EEF and WSH. In Europe, WSH ancestry peaks among Norwegians (ca. 50%) according to , while in South Asia it peaks among the Kalash people (ca. 50%) according to . , however found it at a lower level (ca. 30%) among the Kalash.

In archeogenetica, i pastori delle steppe occidentali (in inglese Western Steppe Herders, abbreviato WSH, o Western Steppe Pastoralists) sono una distinta componente ancestrale che rappresenta la discendenza strettamente correlata alla cultura di Jamna delle steppe pontico-caspiche. I WSH sono considerati discendenti dai cacciatori-raccoglitori orientali (EHG) che ricevettero qualche mescolanza dai cacciatori-raccoglitori caucasici (CHG) durante il Neolitico. Intorno al 3.000 a.C., le genti della cultura di Jamna, appartenenti al cluster genico WSH, intrapresero una massiccia espansione in tutta l'Eurasia che avrebbe portato alla dispersione delle lingue indoeuropee. L'ascendenza WSH di questo periodo è spesso indicata come ascendenza steppica della prima e media Età del bronzo (steppa EMBA). Questa espansione ha portato alla nascita della Cultura della ceramica cordata, i cui membri erano circa al 75% di discendenza WSH, e alla scomparsa virtuale dell'Y-DNA dei primi agricoltori europei (EEF) dal pool genico europeo, alterando in modo significativo il patrimonio genetico dell'Europa. Durante l'età del bronzo, le genti della ceramica cordata mescolatesi con le popolazioni native dell'Europa centrale migrarono nella steppa, formando un tipo di ascendenza WSH spesso denominata ascendenza steppica della media e tarda età del bronzo (Steppa MLBA). La Cultura di Andronovo fu portata in Asia centrale e Asia meridionale insieme alle lingue indoiraniane, lasciando un'eredità culturale e genetica di lunga durata. La popolazione moderna dell'Europa può essere ampiamente modellata come una miscela di WHG (Western Hunter-Gatherer o cacciatori-raccoglitori occidentali), EEF e WSH. In Europa, l'ascendenza WSH raggiunge il picco tra i Norvegesi (circa il 50%), mentre nell'Asia meridionale, raggiunge il picco tra i Kalash (circa il 50%) e i Bramini. (it)
