homeland (), c. 4000 to 1000 BC, according to the widely held
Steppe hypothesis Western Europe Genetic studies have found that Yamnaya autosomal characteristics are very close to the
Corded Ware culture people, with up to 75% Yamnaya-like ancestry in the DNA of Corded Ware skeletons from Central and Eastern Europe. Yamnaya–related ancestry is found in the DNA of modern
Central, and
Northern Europeans (c. 38.8–50.4%), and is also found in lower levels in present-day Southern Europeans (c. 18.5–32.6%),
Sardinians (c. 2.4–7.1%), and
Sicilians (c. 5.9–11.6%). Autosomal tests also indicate that the Yamnaya are the vector for "Ancient North Eurasian" admixture into Europe. "
Ancient North Eurasian" is the name given in literature to a genetic component that represents descent from the people of the
Mal'ta–Buret' culture or a closely related culture. That genetic component is visible in tests of the Yamnaya people, as well as of modern-day Europeans.
Eastern Europe and Finland In the Baltic, Jones et al. (2017) found that the
Neolithic transition, the passage from a hunter-gatherer economy to a farming-based economy, coincided with the arrival en masse of individuals with Yamnaya-like ancestry. That is different from what happened in Western and Southern Europe, where the Neolithic transition was caused by a population that came from Anatolia, with Pontic steppe ancestry being detected from only the late Neolithic onward. Per Haak et al. (2015), the Yamnaya contribution in the modern populations of
Eastern Europe ranges from 46.8% among
Russians to 42.8% in
Ukrainians.
Finland has the highest Yamnaya contributions in all of Europe (50.4%).

Indo-Aryan migrations. There is a significant presence of Yamnaya descent in the nations of South Asia, especially in groups that are referred to as
Indo-Aryans. Lazaridis et al. (2016) estimated (6.5–50.2%) steppe-related admixture in South Asians, though the proportion of Steppe ancestry varies widely across ethnic groups. According to Pathak et al. (2018), the "North-Western Indian & Pakistani" populations (PNWI) showed significant Middle-Late Bronze Age Steppe (Steppe_MLBA) ancestry along with Yamnaya Early-Middle Bronze Age (Steppe_EMBA) ancestry, but the Indo-Europeans of
Gangetic Plains and
Dravidian people showed only significant Yamnaya (Steppe_EMBA) ancestry, no Steppe_MLBA. The study also noted that ancient south Asian samples had significantly higher Steppe_MLBA than Steppe_EMBA (or Yamnaya). According to Narasimhan et al. (2019), the Yamnaya-related ancestry, termed Western_Steppe_EMBA, which reached central and south Asia was not the initial expansion from the steppe to the east but a secondary expansion that involved a group with c. 67% Western_Steppe_EMBA ancestry and c. 33% ancestry from the European cline. The group included people similar to that of
Corded Ware,
Srubnaya,
Petrovka and
Sintashta. Moving further eastward in the central steppe, it acquired c. 9% ancestry from a group of people that possessed West Siberian Hunter Gatherer ancestry and thus formed the Central Steppe MLBA cluster. That is the primary source of steppe ancestry in South Asia and contributes up to 30% of the ancestry of the modern groups in the region. According to Unterländer et al. (2017), all Iron Age
Scythian Steppe nomads can best be described as a mixture of Yamnaya-related ancestry and an
East Asian–related component, which most closely corresponds to the modern North
Siberian
Nganasan people of the lower
Yenisey River, to varying degrees, but generally higher among Eastern Scythians. == See also ==
