Y-chromosome haplogroups from Hun, Avar and conquering Hungarian period nomadic people of the Carpathian Basin

Y chromosome sequencing data suggest dual paths of haplogroup N1a1 into Finland

The paternally inherited Y chromosome is highly informative of genetic ancestry, therefore making it useful in studies of population history. In Finland, two Y-chromosomal haplogroups reveal the major substructure of the population: N1a1 enriched in the northeast and I1a in the southwest, suggested to reflect eastern and western ancestry contributions to the population. Yet, beyond these major Y-chromosomal lineages, the distribution of finer-scale Y-chromosomal variation has not been assessed in Finland. Here, we provide the most comprehensive Y-chromosomal study among the Finns to date, exploiting sequences for 1802 geographically mapped Finnish Y chromosomes from the FINRISK project. We assessed the distribution of common Y-chromosomal haplogroups (frequency ≥1%) throughout 19 Finnish regions and compared the autosomal genetic backgrounds of the Y-chromosomal haplogroups. With such high-resolution data, we were able to find previously unreported sublineages and resolve phylogenetic relationships within haplogroups N1a1 (64%), I1a (25%), R1a (4.3%), and R1b (4.8%). We further find novel geographical enrichment patterns among these Y-chromosomal haplogroups, most notably observed for haplogroup N1a1 dividing into two lineages with differing distributions. While sublineage N-Z1934 (42%) followed a northeastern enrichment pattern observed for all N1a1 carriers in general, sublineage N-VL29 (22%) displayed an enrichment in the southwest. Further, the carriers of N-VL29 showed a higher proportion of southwestern autosomal ancestry compared to carriers of N-Z1934. Collectively, these results point to distinct demographics within haplogroup N1a1, possibly induced by two distinct arrival routes into Finland. Overall, our study suggests a more complex genetic population history for Finns than previously proposed.

'But no living man am I': Bioarchaeological evaluation of the first-known female burial with weapon from the 10th-century-CE Carpathian Basin

Female burials equipped with weapons, a topic of interest among scholars and the general public, remain rare occurrences in archaeological records. The interpretation of such cases requires an interdisciplinary approach and a comprehensive evaluation of the available evidence, particularly regarding the sex and potential lifestyle of the deceased. Consequently, data on specific populations, regions, and time periods remain scarce. For instance, no such case has been reported before concerning the 10th century CE of the Carpathian Basin, known as the Hungarian Conquest period. Our study focuses on an interdisciplinary investigation of a previously known burial, grave No. 63 from the 10th-century-CE cemetery of Sárrétudvari-Hízóföld (eastern Hungary), which represents a unique case with grave goods including jewelry typically associated with females and archery equipment traditionally linked to males. Through archeological, anthropological, and archaeogenetic analyses, we aim to determine if this case represents the first-known female burial with weapon from the 10th-century-CE Carpathian Basin. Despite the poor bone preservation, a factor limiting data recording and evaluation, all analyses consistently indicate that the skeletal remains belonged to a female individual. The burial customs, including weapon equipment composition show analogies with male counterparts in the series. In addition, the pattern of pathological and supposed activity-related changes observed on the bones may have resulted from regular physical activity during her lifetime. In summary, our findings support the identification of this case as the first known female burial with weapon from the 10th-century-CE Carpathian Basin.

Testing the informativeness of Y-STR and mitochondrial DNA control region markers in an attempt to predict ancestry of World War II victims from Slovenian mass grave

Identification of human remains is a challenge in forensic genetics without relatives or personal items available. In Slovenia, a Konfin II mass grave from the Second World War (WWII) was found, containing skeletal remains of 65 victims. The archival documents detailing victims' information describe 45 persons of which 33 could be considered Germanic and 12 Slavic. This study aims to check for concordance between the victim list and actual victims found by using uniparental markers to differentiate between Slavic and non-Slavic origin by attempting to infer ancestry by analyzing the control region (CR) of mitochondrial DNA (mtDNA) and Y-chromosomal STRs. Diaphyses of femurs were used as a DNA source. Next Generation Sequencing (NGS) technology was used for mtDNA- namely HID Ion Chef™ Instrument, Precision ID mtDNA Control Region Panel, and Ion GeneStudio™ S5 System. For the Y-chromosome, PowerPlex® Y23 System (Promega) kit and SeqStudio™ for human identification (HID) were used. European DNA Profiling mtDNA Population Database (EMPOP) and Y-Chromosome STR Haplotype Reference Database (YHRD) were searched for haplotype matches. Closest haplogroups were predicted using EMPOP, Y-DNA Haplogroup Predictor- NevGen, and Whit Athey's Haplogroup Predictor. Despite mitotypes being more diverse than Y-haplotypes, the Y-haplotypes had more database matches and more unequivocal differentiation between populations. 16 victims could be considered Slavic, 15 non-Slavic, and the remaining 34 had a rather scarce informativeness- either unclear or not providing any match. To address ancestry inference more comprehensively, analysis of autosomal ancestry informative markers as well as expansion on haploid markers will be conducted in future research.

Phylogeography of Y-chromosome haplogroup I-P37.2 in Serbian population groups originating from distinct parts of the Balkan Peninsula

Genetic structure of the contemporary Serbian population was shaped by a long history of turbulent historical and demographical events. The most important migrations of Serbs towards present day Serbia, in the recent history, occurred between the 15th to the 18th century from the regions of Old Herzegovina and Kosovo and Metohija. Previous haplogroup analysis revealed wide spectrum of main haplogroups, among which haplogroup I-P37.2 was the most frequent one in Serbian population groups originating from the Balkan Peninsula. Within this study 464 Serbian males samples from three geographical regions in the Balkan Peninsula inhabited by Serbs: present-day Serbia, regions of Old Herzegovina and Kosovo and Metohija, previously classified as haplogroup I-P37.2, were genotyped using the 22 Y-single nucleotide polymorphisms (Y-SNPs) in order to determine deeper phylogenetic and phylogeographic analysis of haplogroup I-P37.2. Based on SNP typing all samples in the Old Herzegovina and present-day Serbia dataset and 122 out of 128 samples from Kosovo and Metohija were assigned to haplogroup I-L621. Further SNP typing revealed very similar haplogroup distribution in all datasets, with the predominant haplogroup being I-PH908, followed by haplogroup I-Z17855. Analysis within haplogroup I-PH908 distinguished haplogroup I-FT14506 as the most frequent in the Kosovo and Metohija dataset, while haplogroup I-FT16449 was the most frequent in the Old Herzegovina dataset. In the present-day Serbia dataset, occurrence of haplogroups I-FT14506 and I-FT16449 was almost equal, comprising 40.2 % and 34.4 %, respectively. Low level of differentiation, within haplogroup I-PH908, was detected between all datasets, with the lowest one detected between present-day Serbia and Old Herzegovina datasets and highest one between Kosovo and Metohija and Old Herzegovina datasets. Furthermore, median-joining network analysis and shared haplotypes statistics revealed closer genetic relationship between Old Herzegovina and present-day Serbia haplotypes. Results obtained within this study support the thesis that migrations from historical region of Old Herzegovina and geographical region of Kosovo and Metohija, had great contribution on the present-day Serbian population genetic structure. Furthermore, here presented results, gave insight into geographic distribution of detected haplogroups I-Z17855, I-Y4460, I-PH908, I-Y5596, I-Y4882, I-FT14506, I-FT16449 and I-A5913 and analyzed SNPs, enabling further improvement of the geographic resolution of paternal ancestry inference.

Phylogenetic insights into the genetic legacies of Hungarian-speaking communities in the Carpathian Basin

This study focuses on exploring the uniparental genetic lineages of Hungarian-speaking minorities residing in rural villages of Baranja (Croatia) and the Zobor region (Slovakia). We aimed to identify ancestral lineages by examining genetic markers distributed across the entire mitogenome and on the Y-chromosome. This allowed us to discern disparities in regional genetic structures within these communities. By integrating our newly acquired genetic data from a total of 168 participants with pre-existing Eurasian and ancient DNA datasets, our goal was to enrich the understanding of the genetic history trajectories of Carpathian Basin populations. Our findings suggest that while population-based analyses may not be sufficiently robust to detect fine-scale uniparental genetic patterns with the sample sizes at hand, phylogenetic analysis of well-characterized Y-chromosomal Short Tandem Repeat (STR) data and entire mitogenome sequences did uncover multiple lineage ties to far-flung regions and eras. While the predominant portions of both paternal and maternal DNA align with the East-Central European spectrum, rarer subhaplogroups and lineages have unveiled ancient ties to both prehistoric and historic populations spanning Europe and Eastern Eurasia. This research augments the expansive field of phylogenetics, offering critical perspectives on the genetic constitution and heritage of the communities in East-Central Europe.

Sexual activity in a large representative cohort of Polish men: Frequency, number of partners, correlates, and quality of life

INTRODUCTION

Sexual activity of men has been evaluated at the population-level in different regions of the world. However, reliable data are lacking for Eastern Europe. Therefore, the aim of this study was to analyze the frequency of sexual activity and the number of sexual partners in a large representative cohort of Polish men.

METHODS

We performed a cross-sectional investigation with computer-assisted web interviews. Participants were stratified by age (≥18 years) and place of residence. The most recent population census was used to produce a population-representative sample of respondents. Men's sexual activity was then correlated with multiple variables.

RESULTS

We enrolled 3001 men, representative for age and place of residence, including adequate proportions of respondents from urban and rural areas. Most Polish men were sexually active, predominantly having had sex at least weekly with one partner. Almost 18% of respondents declined sexual intercourse and/or sexual partner in the prior year. The highest sexual activity was observed for men 35-44-years-old (for sex frequency) and 18-24-years-old (for partner number), living in medium-sized cities, employed, and married (for sex frequency) or divorced (for partner number). Erectile dysfunction negatively affected the frequency of sexual activity and lowered the number of sexual partners, although premature ejaculation did not have any effect. Frequency of sexual activity and number of sexual partners correlated well with psychological distress, quality of sex life, and overall life quality. Whereas lifestyle habits including smoking and alcohol intake decreased the likelihood of sexual activity, all analyzed comorbidities did not affect sex life.

CONCLUSIONS

This study of men's sexual activity was the first population-representative and nationwide investigation performed in Poland. Most Polish men were sexually active and sexual activity correlated with multiple variables including sociodemographic factors, erectile functioning, mental distress, overall and sex-specific quality of life, and lifestyle habits.

Genetic identification of members of the prominent Báthory aristocratic family

The Báthory family was one of the most powerful noble families in the medieval Hungarian Kingdom. Their influence peaked during the Ottoman occupation of Hungary, when the only partially autonomous region of the country was Transylvania, under Turkish protectorate. Several members of the family became Princes of Transylvania, and one of them, István Báthory, was also the elected King of Poland. We hereby present the first genetic data about this extinct family. Archaeological excavations in Pericei, a settlement now part of Romania, revealed the former family chapel of the Báthory family. Through this work, two Báthory family members were successfully identified among the 13 skeletons found at the site. The presence of Y chromosome haplogroup R-S498 fits the historical account describing the family's German (Swabian) origins. Their genomic composition also indicates a family of Germanic origin that intermixed with medieval Hungarians.

Integrating Linguistic, Archaeological and Genetic Perspectives Unfold the Origin of Ugrians

In the last year two publications shed new light on the linguistic and genomic history of ancient Uralic speakers. Here I show that these novel genetic and linguistic data are compatible with each-other and with the archaeological inferences, allowing us to formulate a very plausible hypothesis about the prehistory of Ugric speakers. Both genetic and archaeological data indicate the admixture of the Mezhovskaya population with northern forest hunters in the late Bronze Age, which gave rise to a "proto-Ugric" community. This finding is consistent with the linguistic reconstruction of the proto-Ugric language. Genetic data indicate an admixture of proto-Hungarians with early Sarmatians and early Huns, and I show that the first admixture can be reconciled with the formation of the Gorokhovo culture and its integration into the early Sarmatian Prokhorovka culture, while the second admixture corresponds to the transformation of the Sargat and Sarmatian cultures due to Xiongnu invasions.

High Coverage Mitogenomes and Y-Chromosomal Typing Reveal Ancient Lineages in the Modern-Day Székely Population in Romania

Here we present 115 whole mitogenomes and 92 Y-chromosomal Short Tandem Repeat (STR) and Single Nucleotide Polymorphism (SNP) profiles from a Hungarian ethnic group, the Székelys (in Romanian: Secuii, in German: Sekler), living in southeast Transylvania (Romania). The Székelys can be traced back to the 12th century in the region, and numerous scientific theories exist as to their origin. We carefully selected sample providers that had local ancestors inhabiting small villages in the area of Odorheiu Secuiesc/Székelyudvarhely in Romania. The results of our research and the reported data signify a qualitative leap compared to previous studies since it presents the first complete mitochondrial DNA sequences and Y-chromosomal profiles of 23 STRs from the region. We evaluated the results with population genetic and phylogenetic methods in the context of the modern and ancient populations that are either geographically or historically related to the Székelys. Our results demonstrate a predominantly local uniparental make-up of the population that also indicates limited admixture with neighboring populations. Phylogenetic analyses confirmed the presumed eastern origin of certain maternal (A, C, D) and paternal (Q, R1a) lineages, and, in some cases, they could also be linked to ancient DNA data from the Migration Period (5th-9th centuries AD) and Hungarian Conquest Period (10th century AD) populations.

The paternal genetic legacy of Hungarian-speaking Rétköz (Hungary) and Váh valley (Slovakia) populations

One hundred and six Rétköz and 48 Váh valley samples were collected from the contact zones of Hungarian-Slovakian territories and were genotyped for Y-chromosomal haplotypes and haplogroups. The results were compared with contemporary and archaic data from published sources. The genetic composition of the Rétköz population from Hungary and the Váh valley population from Slovakia indicates different histories. In the Rétköz population, the paternal lineages that were also found in the Hungarian Conquerors, such as R1a-Z93, N-M46, Q-M242, and R1b-L23, were better preserved. These haplogroups occurred in 10% of the population. The population of the Váh valley, however, is characterized by the complete absence of these haplogroups. Our study did not detect a genetic link between the Váh valley population and the Hungarian Conquerors; the genetic composition of the Váh valley population is similar to that of the surrounding Indo-European populations. The Hungarian Rétköz males shared common haplotypes with ancient Xiongnu, ancient Avar, Caucasian Avar, Abkhazian, Balkarian, and Circassian males within haplogroups R1a-Z93, N1c-M46, and R1b-L23, indicating a common genetic footprint. Another difference between the two studied Hungarian populations can be concluded from the Fst-based MDS plot. The Váh valley, in the western part of the Hungarian-Slovakian contact zone, is genetically closer to the Western Europeans. In contrast, Rétköz is in the eastern part of that zone and therefore closer to the Eastern Europeans.

Tracing genetic connections of ancient Hungarians to the 6th-14th century populations of the Volga-Ural region

Most of the early Hungarian tribes originated from the Volga-Kama and South-Ural regions, where they were composed of a mixed population based on historical, philological and archaeological data. We present here the uniparental genetic makeup of the mediaeval era of these regions that served as a melting pot for ethnic groups with different linguistic and historical backgrounds. Representing diverse cultural contexts, the new genetic data originate from ancient proto-Ob-Ugric people from Western Siberia (6th-13th century), the pre-Conquest period and subsisting Hungarians from the Volga-Ural region (6th-14th century) and their neighbours. By examining the eastern archaeology traits of Hungarian prehistory, we also study their genetic composition and origin in an interdisciplinary framework. We analyzed 110 deep-sequenced mitogenomes and 42 Y-chromosome haplotypes from 18 archaeological sites in Russia. The results support the studied groups' genetic relationships regardless of geographical distances, suggesting large-scale mobility. We detected long-lasting genetic connections between the sites representing the Kushnarenkovo and Chiyalik cultures and the Carpathian Basin Hungarians and confirmed the Uralic transmission of several East Eurasian uniparental lineages in their gene pool. Based on phylogenetics, we demonstrate and model the connections and splits of the studied Volga-Ural and conqueror groups. Early Hungarians and their alliances conquered the Carpathian Basin around 890 AD. Re-analysis of the Hungarian conquerors' maternal gene pool reveals numerous surviving maternal relationships in both sexes; therefore, we conclude that men and women came to the Carpathian Basin together, and although they were subsequently genetically fused into the local population, certain eastern lineages survived for centuries.

Distribution of Y-chromosome haplogroups in Serbian population groups originating from historically and geographically significant distinct parts of the Balkan Peninsula

Our study enrolled 1200 Serbian males originating from three geographical regions in the Balkan Peninsula inhabited by Serbs: present-day Serbia, regions of Old Herzegovina and Kosovo and Metohija. These samples were genotyped using the combination of 23 Y-chromosomal short tandem repeats (Y-STRs) loci and 17 Ychromosomal single nucleotide polymorphisms (Y-SNPs) loci for the haplotype and haplogroup analysis in order to characterize in detail Y chromosome flow in the recent history. Serbia's borders have changed through history, forcing Serbs constantly to migrate to different regions of Balkan Peninsula. The most significant migration waves in the recent history towards present-day Serbia occurred from the regions of Old- Herzegovina and Kosovo and Metohija that lie in the south-west/south. High haplotype diversity and discrimination capacity were observed in all three datasets, with the highest number of unique haplotypes (381) and discrimination capacity (0.97) detected in the samples originating from the present-day Serbia. Haplogroup composition didn't differ significantly among datasets, with three dominant haplogroups (I-M170, E-P170 and R-M198), and haplogroup I-M170 being the most frequent in all three datasets. Haplogroup E-P170 was the second most dominant in the dataset originating from geographical region of Kosovo and Metohija, whereas haplogroup R-M198 was the second most prevalent in the dataset from historical region of Old Herzegovina. Based on the phylogenetic three for haplogroup I constructed within this study, haplogroup I2a1-P37.2 was the most dominant within all three datasets, especially in the dataset from historical region of Old Herzegovina, where 182 out of 400 samples were derived for SNP P37.2. Genetic distances between three groups of samples, evaluated by the Fst and Rst statistical values, and further visualized through multidimensional scaling plot, showed great genetic similarity between datasets from Old Herzegovina and present-day Serbia. Genetic difference in the haplogroup distribution and frequency between datasets from historical region of Old Herzegovina and from geographical region of Kosovo and Metohija was confirmed with highest Fst and Rst vaules. In this study we have distinguished genetic structure, diversity and haplogroup frequencies within 1200 Serbian males from three datasets, relationships among them as well as with other Balkan and European populations, which is useful for studying recent demographic history.

The genetic origin of Huns, Avars, and conquering Hungarians

Huns, Avars, and conquering Hungarians were migration-period nomadic tribal confederations that arrived in three successive waves in the Carpathian Basin between the 5^th and 9^th centuries. Based on the historical data, each of these groups are thought to have arrived from Asia, although their exact origin and relation to other ancient and modern populations have been debated. Recently, hundreds of ancient genomes were analyzed from Central Asia, Mongolia, and China, from which we aimed to identify putative source populations for the above-mentioned groups. In this study, we have sequenced 9 Hun, 143 Avar, and 113 Hungarian conquest period samples and identified three core populations, representing immigrants from each period with no recent European ancestry. Our results reveal that this "immigrant core" of both Huns and Avars likely originated in present day Mongolia, and their origin can be traced back to Xiongnus (Asian Huns), as suggested by several historians. On the other hand, the "immigrant core" of the conquering Hungarians derived from an earlier admixture of Mansis, early Sarmatians, and descendants of late Xiongnus. We have also shown that a common "proto-Ugric" gene pool appeared in the Bronze Age from the admixture of Mezhovskaya and Nganasan people, supporting genetic and linguistic data. In addition, we detected shared Hun-related ancestry in numerous Avar and Hungarian conquest period genetic outliers, indicating a genetic link between these successive nomadic groups. Aside from the immigrant core groups, we identified that the majority of the individuals from each period were local residents harboring "native European" ancestry.

Ancient genomes reveal origin and rapid trans-Eurasian migration of 7th century Avar elites

The Avars settled the Carpathian Basin in 567/68 CE, establishing an empire lasting over 200 years. Who they were and where they came from is highly debated. Contemporaries have disagreed about whether they were, as they claimed, the direct successors of the Mongolian Steppe Rouran empire that was destroyed by the Turks in ∼550 CE. Here, we analyze new genome-wide data from 66 pre-Avar and Avar-period Carpathian Basin individuals, including the 8 richest Avar-period burials and further elite sites from Avar's empire core region. Our results provide support for a rapid long-distance trans-Eurasian migration of Avar-period elites. These individuals carried Northeast Asian ancestry matching the profile of preceding Mongolian Steppe populations, particularly a genome available from the Rouran period. Some of the later elite individuals carried an additional non-local ancestry component broadly matching the steppe, which could point to a later migration or reflect greater genetic diversity within the initial migrant population.

Maternal Lineages of Gepids from Transylvania

According to the written historical sources, the Gepids were a Germanic tribe that settled in the Carpathian Basin during the Migration Period. They were allies of the Huns, and an independent Gepid Kingdom arose after the collapse of the Hun Empire. In this period, the Carpathian Basin was characterized by so-called row-grave cemeteries. Due to the scarcity of historical and archaeological data, we have a poor knowledge of the origin and composition of these barbarian populations, and this is still a subject of debate. To better understand the genetic legacy of migration period societies, we obtained 46 full mitogenome sequences from three Gepid cemeteries located in Transylvania, Romania. The studied samples represent the Classical Gepidic period and illustrate the genetic make-up of this group from the late 5th and early 6th centuries AD, which is characterized by cultural markers associated with the Gepid culture in Transylvania. The genetic structure of the Gepid people is explored for the first time, providing new insights into the genetic makeup of this archaic group. The retrieved genetic data showed mainly the presence of Northwestern European mitochondrial ancient lineages in the Gepid group and all population genetic analyses reiterated the same genetic structure, showing that early ancient mitogenomes from Europe were the major contributors to the Gepid maternal genetic pool.

Genome-wide autosomal, mtDNA, and Y chromosome analysis of King Bela III of the Hungarian Arpad dynasty

The ancient Hungarians, "Madzsars", established their control of the Carpathian Basin in the late ninth century and founded the Hungarian Kingdom around 1000AD. The origin of the Magyars as a tribal federation has been much debated in the past. From the time of the conquest to the early fourteenth century they were ruled by descendants of the Arpad family. In order to learn more about the genetic origin of this family, we here analyzed the genome of Bela III one of the most prominent members of the early Hungarian dynasty that ruled the Hungarian Kingdom from 1172 to 1196. The Y-Chromosome of Bela III belongs to haplogroup R1a-Z2123 that is today found in highest frequency in Central Asia, supporting a Central Asian origin for the ruling lineage of the Hungarian kingdom. The autosomal DNA profile of Bela III, however, falls within the genetic variation of present-day east European populations. This is further supported through his mtDNA genome that belongs to haplogroup H, the most common European maternal lineage, but also found in Central Asia. However, we didn't find an exact haplotype match for Bela III. The typical autosomal and maternal Central Eastern European ancestry among Bela III autosomes might be best explained by consecutive intermarriage with local European ruling families.

Biologia futura: confessions in genes

Y-DNA and mtDNA have been a widely used tool not only in forensic genetic applications but in human evolutionary and population genetic studies. Its paternal or maternal inheritance and lack of recombination have offered the opportunity to explore genealogical relationships among individuals and to study the frequency differences of paternal and maternal clades among human populations at continental and regional levels. It is unbelievable, but true, that the disadvantages of paternal and maternal lineages in forensic genetic studies, i.e., everyone within a family have the same paternal or maternal haplotype and haplogroup, become advantages in human evolutionary studies, i.e., reveal the genetic history of successful mothers and successful fathers. Thanks to these amazing properties of haploid markers, they provide tools for mapping the migration routes of human populations during prehistoric and historical periods, separately as maternal and paternal lineages, and together as the genetic history of a population.

Maternal Lineages from 10-11th Century Commoner Cemeteries of the Carpathian Basin

Nomadic groups of conquering Hungarians played a predominant role in Hungarian prehistory, but genetic data are available only from the immigrant elite strata. Most of the 10-11th century remains in the Carpathian Basin belong to common people, whose origin and relation to the immigrant elite have been widely debated. Mitogenome sequences were obtained from 202 individuals with next generation sequencing combined with hybridization capture. Median joining networks were used for phylogenetic analysis. The commoner population was compared to 87 ancient Eurasian populations with sequence-based (Fst) and haplogroup-based population genetic methods. The haplogroup composition of the commoner population markedly differs from that of the elite, and, in contrast to the elite, commoners cluster with European populations. Alongside this, detectable sub-haplogroup sharing indicates admixture between the elite and the commoners. The majority of the 10-11th century commoners most likely represent local populations of the Carpathian Basin, which admixed with the eastern immigrant groups (which included conquering Hungarians).

Determination of the phylogenetic origins of the Árpád Dynasty based on Y chromosome sequencing of Béla the Third

We set out to identify the origins of the Árpád Dynasty based on genome sequencing of DNA derived from the skeletal remains of Hungarian King Béla III (1172-1196) and eight additional individuals (six males, two females) originally interred at the Royal Basilica of Székesfehérvár. Y-chromosome analysis established that two individuals, Béla III and HU52 assign to haplogroups R-Z2125 whose distribution centres near South Central Asia with subsidiary expansions in the regions of modern Iran, the Volga Ural region and the Caucasus. Out of a cohort of 4340 individuals from these geographic areas, we acquired whole-genome data from 208 individuals derived for the R-Z2123 haplogroup. From these data we have established that the closest living kin of the Árpád Dynasty are R-SUR51 derived modern day Bashkirs predominantly from the Burzyansky and Abzelilovsky districts of Bashkortostan in the Russian Federation. Our analysis also reveals the existence of SNPs defining a novel Árpád Dynasty specific haplogroup R-ARP. Framed within the context of a high resolution R-Z2123 phylogeny, the ancestry of the first Hungarian royal dynasty traces to the region centering near Northern Afghanistan about 4500 years ago and identifies the Bashkirs as their closest kin, with a separation date between the two populations at the beginning of the first millennium CE.

Cost-effective straightforward method for captured whole mitogenome sequencing of ancient DNA

Working with mitochondrial DNA from highly degraded samples is challenging. We present a whole mitogenome Illumina-based sequencing method suitable for highly degraded samples. The method makes use of double-stranded library preparation with hybridization-based target enrichment. The aim of the study was to implement a new user-friendly method for analysing many ancient DNA samples at low cost. The method combines the Swift 2S™ Turbo library preparation kit and xGen® panel for mitogenome enrichment. Swift allows to use low input of aDNA and own adapters and primers, handles inhibitors well, and has only two purification steps. xGen is straightforward to use and is able to leverage already pooled libraries. Given the ancient DNA is more challenging to work with, the protocol was developed with several improvements, especially multiplying DNA input in case of low concentration DNA extractions followed by AMPure® beads size selection and real-time pre-capture PCR monitoring in order to avoid cycle-optimization step. Nine out of eleven analysed samples successfully retrieved mitogenomes. Hence, our method provides an effective analysis of whole mtDNA, and has proven to be fast, cost-effective, straightforward, with utilisation in population-wide research of burial sites.

Early medieval genetic data from Ural region evaluated in the light of archaeological evidence of ancient Hungarians

The ancient Hungarians originated from the Ural region of Russia, and migrated through the Middle-Volga region and the Eastern European steppe into the Carpathian Basin during the ninth century AD. Their Homeland was probably in the southern Trans-Ural region, where the Kushnarenkovo culture was disseminated. In the Cis-Ural region Lomovatovo and Nevolino cultures are archaeologically related to ancient Hungarians. In this study we describe maternal and paternal lineages of 36 individuals from these regions and nine Hungarian Conquest period individuals from today's Hungary, as well as shallow shotgun genome data from the Trans-Uralic Uyelgi cemetery. We point out the genetic continuity between the three chronological horizons of Uyelgi cemetery, which was a burial place of a rather endogamous population. Using phylogenetic and population genetic analyses we demonstrate the genetic connection between Trans-, Cis-Ural and the Carpathian Basin on various levels. The analyses of this new Uralic dataset fill a gap of population genetic research of Eurasia, and reshape the conclusions previously drawn from tenth to eleventh century ancient mitogenomes and Y-chromosomes from Hungary.

Genetic evidence suggests a sense of family, parity and conquest in the Xiongnu Iron Age nomads of Mongolia

In an effort to characterize the people who composed the groups known as the Xiongnu, nuclear and whole mitochondrial DNA data were generated from the skeletal remains of 52 individuals excavated from the Tamir Ulaan Khoshuu (TUK) cemetery in Central Mongolia. This burial site, attributed to the Xiongnu period, was used from the first century BC to the first century AD. Kinship analyses were conducted using autosomal and Y-chromosomal DNA markers along with complete sequences of the mitochondrial genome. These analyses suggested close kin relationships between many individuals. Nineteen such individuals composed a large family spanning five generations. Within this family, we determined that a woman was of especially high status; this is a novel insight into the structure and hierarchy of societies from the Xiongnu period. Moreover, our findings confirmed that the Xiongnu had a strongly admixed mitochondrial and Y-chromosome gene pools and revealed a significant western component in the Xiongnu group studied. Using a fine-scale approach (haplotype instead of haplogroup-level information), we propose Scytho-Siberians as ancestors of the Xiongnu and Huns as their descendants.

Early nomads of the Eastern Steppe and their tentative connections in the West

The origin of the Xiongnu and the Rourans, the nomadic groups that dominated the eastern Eurasian steppe in the late first millennium BC/early first millennium AD, is one of the most controversial topics in the early history of Inner Asia. As debatable is the evidence linking these two groups with the steppe nomads of early medieval Europe, i.e. the Huns and the Avars, respectively. In this paper, we address the problems of Xiongnu-Hun and Rouran-Avar connections from an interdisciplinary perspective, complementing current archaeological and historical research with a critical analysis of the available evidence from historical linguistics and population genetics. Both lines of research suggest a mixed origin of the Xiongnu population, consisting of eastern and western Eurasian substrata, and emphasize the lack of unambiguous evidence for a continuity between the Xiongnu and the European Huns. In parallel, both disciplines suggest that at least some of the European Avars were of Eastern Asian ancestry, but neither linguistic nor genetic evidence provides a sufficient support for a specific connection between the Avars and the Asian Rourans.
