A Dynamic 6,000-Year Genetic History of Eurasia's Eastern Steppe

The Eastern Eurasian Steppe was home to historic empires of nomadic pastoralists, including the Xiongnu and the Mongols. However, little is known about the region's population history. Here, we reveal its dynamic genetic history by analyzing new genome-wide data for 214 ancient individuals spanning 6,000 years. We identify a pastoralist expansion into Mongolia ca. 3000 BCE, and by the Late Bronze Age, Mongolian populations were biogeographically structured into three distinct groups, all practicing dairy pastoralism regardless of ancestry. The Xiongnu emerged from the mixing of these populations and those from surrounding regions. By comparison, the Mongols exhibit much higher eastern Eurasian ancestry, resembling present-day Mongolic-speaking populations. Our results illuminate the complex interplay between genetic, sociopolitical, and cultural changes on the Eastern Steppe

Available on open access from Nature Research via the DOI in this recordData availability: All collapsed and paired-end sequence data for samples sequenced in this study are available in compressed fastq format through the European Nucleotide Archive under accession number PRJEB44430, together with rescaled and trimmed bam sequence alignments against both the nuclear and mitochondrial horse reference genomes. Previously published ancient data used in this study are available under accession numbers PRJEB7537, PRJEB10098, PRJEB10854, PRJEB22390 and PRJEB31613, and detailed in Supplementary Table 1.

However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling at Botai, Central Asia around 3500 BC. Other longstanding candidate regions for horse domestication, such as Iberia and Anatolia, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 BC, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 BC driving the spread of Indo-European languages. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium BC Sintashta culture

The origins and spread of domestic horses from the Western Eurasian steppes

Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region.Domestication of horses fundamentally transformed long-range mobility and warfare(1).

The results of selection and breeding activities for white goats of Zalaajinst-Edren breed

The population of white goats created by continues research and sound selection under the Gobi ecological and climatic conditions was recognized as a distinct cashmere breed of Zalaajinst-Edren white goats in 2015 by a decree # A/59, of the Minister of Food and Agriculture of Mongolia [7]. Studies carried out in Shinejinst and Bayan-Undur soums of Bayankhongor aimag in 2011-2016 were to review the results of the work undertaken for crossing of native goats and crossbreds from the Gobi Gurvan Saikhan breed and native goats with bucks of Zalaajinst white strain. The objective of this work was to evaluate the outputs of previously conducted studies on inheritance of body color and achievements of introduced selective breeding schemes and to investigate options for further consolidation of key productive and phenotypic performances such as body color, cashmere yield and fiber quality. The size of herds of Zalaajinst-Edren breed raised in Shinejinst and Bayan-Undur soums, home to the nucleus herds has reached 217.5 thousand heads including 47.8 thousand heads of desirable type - representing the breed. Thus, the number of goats satisfies the limits allowing entering into straight breeding and kick-off line breeding exercises using existing genealogical lines: “Zalaa” – fine cashmere fiber, “Suvdan” - large body size, “Myandsan” with long cashmere fiber and “Edren” producing the most fine cashmere [6].The distinctive features of goats of Zalaajinst-Edren white breed is that they give pure white cashmere with unique quality yielding at 406.3 grams of fine down of 15.1 microns in fiber diameter and 68.6 mm in length. The pure cashmere yield is measured at 47.0-57.05 percent. No major differences in liveweight and milk and meat productivity have been recorded between Zalaajinst-Edren white breed and other cashmere flocks in Mongolia [7]
