    Testimony from the Bones of Hungarian King Béla III – Origins of the Árpád Dynasty.
    The role of applications based on machine learning is continuously growing in the industry, health sector/bioinformatics and scientific research. American researchers published a bit more than 10 years ago the first machine learning algorithms, which were able to safely predict Y-SNP based haplogroups from Y-STR data.

    The goal of the present study was to predict with machine learning algorithms the SNP-based subgroup of three ancient DNA samples (King Béla III and two Khazar samples) belonging to Y-DNA Haplogroup R1a, in order to predict their geographic origin and mutual genetic relatedness more accurately. This is the first study applying machine learning algorithms for researching Hungarian prehistory.
    Based on the Y-STR haplotype of King Béla III, we estimated with the machine learning algorithm in the first step that he belonged to the R1a-Z93 subgroup that is most common among Indo-Iranic and Turkic speaking peoples. The second step predicted that King Béla III belonged to the Z2123 subgroup of R1a-Z93. The Phylogenetic analysis showed King Béla III most likely belonged to the relatively rare YP451+ YP449- subgroup of Z2123, which practically only appears in the North Caucasus, especially among Karachays and Balkars.
    Based on our results, we could hypothetically conclude that the Árpád Dynasty has common origin with one ethnic component of the Karachay people.
    In our study we proved that it is possible to increase the accuracy of Y-DNA haplogroup prediction of historical aDNA samples with mathematical methods using contemporary Y-STR haplotypes. With the help of this method, larger historical aDNA studies could save a lot of research funds and DNA carrying out tailored deep SNP-testing of samples instead of using general SNaPshots.
    Keywords: Physical anthropology; Archaeogenetics; Machine learning; Y-SNP prediction; Y-STR; Gradient boosting; Árpád Dynasty; King Béla III; Hungarian ethnogenesis.

    Genetic history of Bashkirian Mari and Southern Mansi ethnic groups in the Ural region

    https://link.springer.com/article/10...38-019-01555-x

    According to genetic studies, the Hungarian Y-chromosomal gene pool significantly differs from other Uralic-speaking populations. Hungarians possess a significant frequency of haplogroup R1a-Z280 and a low frequency of haplogroup N-Tat, which is common among other Uralic-speaking populations. Based on this evidence, we further worked to define the links between the linguistically related Hungarian, Mansi and Bashkirian Mari populations. Samples were collected from 45 Bashkirian Mari and 36 Southern Mansi males in the Ural region. We analyzed male-specific markers including 23 STRs and 36 SNPs, which reflect past and recent paternal genetic history. We found that the haplogroup distribution of the two population samples showed high genetic similarity to each other except for the N-Tat* and R1a-Z93 haplogroups in the Bashkirian Mari males. On the MDS plots constructed from Fst- and Rst-genetic distances, the Bashkirian Mari and Southern Mansi population groups showed close genetic affinities with the Khanty, Northern Mansi, Mari, and Estonian populations. For phylogenetic studies, networks were constructed for the most frequent haplogroups in both populations together with other Eurasian populations. Both populations shared common haplotypes within haplogroups R1a-Z280 or N-L1034 with Hungarian speakers, suggesting a common paternal genetic footprint that arose in prehistoric or historic times. Overall, the Hungarian, Mansi, and Bashkirian Mari populations have a much more complex genetic history than the traditional linguistic model or history would suggest. Further studies are needed to clarify the common genetic profiles may have been acquired directly or indirectly during the more or less known their history.

    Very new results. I think it's very interesting:

    https://www.yfull.com/tree/Q-YP1695/

    It seems, here is an 1100 years old pure hungarian bloodline from Inner Asia.

    id:YF02841 is from East-Kazahstan. Yessembayev from the nayman tribe.
    id:ERS2374408 is an ancient DNA sample from a tomb of a 2500 years old scythian warrior. The location: near the Tien-shan, East-Kazahstan.

    Abstract

    Hungarians who live in Central Europe today are one of the westernmost Uralic speakers. Despite of the proposed Volga-Ural/West Siberian roots of the Hungarian language, the present-day Hungarian gene pool is highly similar to that of the surrounding Indo-European speaking populations. However, a limited portion of specific Y-chromosomal lineages from haplogroup N, sometimes associated with the spread of Uralic languages, link modern Hungarians with populations living close to the Ural Mountain range on the border of Europe and Asia. Here we investigate the paternal genetic connection between these spatially separated populations. We reconstruct the phylogeny of N3a4-Z1936 clade by using 33 high-coverage Y-chromosomal sequences and estimate the coalescent times of its sub-clades. We genotype close to 5000 samples from 46 Eurasian populations to show the presence of N3a4-B539 lineages among Hungarians and in the populations from Ural Mountain region, including Ob-Ugric-speakers from West Siberia who are geographically distant but linguistically closest to Hungarians. This sub-clade splits from its sister-branch N3a4-B535, frequent today among Northeast European Uralic speakers, 4000–5000 ya, which is in the time-frame of the proposed divergence of Ugric languages.

    How can you see to whom the ancient DNA belongs on YFull?
