Scythians are known from written sources as horse-riding nomadic peoples who dominated the Eurasian steppe throughout the Iron Age. However, their origins and the exact nature of their social organization remain debated. Three hypotheses prevail regarding their origins that can be summarized as a “western origin”, an “eastern origin” and a “multi-regional origin”. In this work, we first aimed to address the question of the familial and social organization of some Scythian groups (Scytho… 
New genetic evidence of affinities and discontinuities between bronze age Siberian populations.
TLDR
The hypothesis of a genetic link between Afanasievo and Yamnaya (in western Eurasia), as suggested by previous studies of other markers, is supported and the presence of Y-haplogroup Q in Okunevo individuals links them to Native American populations, as was suggested by whole-genome sequencing.
Genetic evidence suggests a sense of family, parity and conquest in the Xiongnu Iron Age nomads of Mongolia
TLDR
Using a fine-scale approach (haplotype instead of haplogroup-level information), Scytho-Siberians are proposed as ancestors of the Xiongnu and Huns as their descendants and a woman was of especially high status within this family.
The limitations of kinship determinations using STR data in ill-defined populations
TLDR
It is shown that the application of LR to both test populations highlights specific issues that prevent the confirmation of second-degree kinship or even full siblingship in small populations, and recommends a conservative approach to kinship determined by LR.
Paleodemographic analysis of age at death for a population of Black Sea Scythians: An exploration by using Bayesian methods.
TLDR
A way to overcome some limitations of broad age categorization is shown by using the Bayesian approach with alternative model specifications, allowing to assess the impact of reference populations.
Mitochondrial Haplogroup Classification of Ancient DNA Samples Using Haplotracker
TLDR
Using Haplotracker, a straightforward and efficient high-resolution haplogroup classification tool optimized specifically for ancient DNA samples, mitochondrial haplogroups are classified to the final subhaplogroup level in nine ancientDNA samples extracted from human skeletal remains found in 2,000-year-old elite Xiongnu cemetery in Northeast Mongolia.

Diverse origin of mitochondrial lineages in Iron Age Black Sea Scythians
TLDR
An overall similarity in mtDNA lineages of the NPR Scythians was found with the late Bronze Age Srubnaya population of the Northern Black Sea region which supports the archaeological hypothesis suggesting SrubNaya people as ancestors of theNPR Scythian.
Ancestry and demography and descendants of Iron Age nomads of the Eurasian Steppe
TLDR
Genomic inference reveals that Scythians in the east and the west of the steppe zone can best be described as a mixture of Yamnaya-related ancestry and an East Asian component, and finds evidence that significant gene-flow from east to west Eurasia must have occurred early during the Iron Age.
Ancient DNA provides new insights into the history of south Siberian Kurgan people
TLDR
The data indicate that at the Bronze and Iron Age timeframe, south Siberians were blue (or green)-eyed, fair-skinned and light-haired people and that they might have played a role in the early development of the Tarim Basin civilization.
Genetic analysis and ethnic affinities from two Scytho-Siberian skeletons.
TLDR
Comparison with the haplogroup of 3,523 Asian and American individuals linked one skeleton with a putative ancestral paleo-Asiatic population and the other with Chinese populations.
Ancient genomes suggest the eastern Pontic-Caspian steppe as the source of western Iron Age nomads
TLDR
The authors found evidence of a stable shared genetic signature, making the eastern Pontic-Caspian steppe a likely source of western nomadic groups, and suggest that, despite genetic links among these peoples, no group can be considered a direct ancestor of the subsequent group.
Genetic Analysis of a Scytho-Siberian Skeleton and Its Implications for Ancient Central Asian Migrations
TLDR
DNA extracted from a bone sample revealed a skeleton belonging to the Scytho-Siberian population and the resulting STR profile, mitochondrial haplotype, and haplogroup were compared with data from modern Eurasian and northern native American populations and were found only in European populations historically influenced by ancient nomadic tribes of Central Asia.
Parallel paleogenomic transects reveal complex genetic history of early European farmers
TLDR
Investigating the population dynamics of Neolithization across Europe using a high-resolution genome-wide ancient DNA dataset with a total of 180 samples finds that genetic diversity was shaped predominantly by local processes, with varied sources and proportions of hunter-gatherer ancestry among the three regions and through time.
A genetic perspective on Longobard-Era migrations
TLDR
87 new complete mitochondrial sequences coming from nine early-medieval cemeteries located along the area interested by the Longobard migration (Czech Republic, Hungary and Italy) are reported, indicating a complex dynamics of admixture in medieval Europe.
