Maternal Genetic Ancestry and Legacy of 10(th) Century AD Hungarians.

The ancient Hungarians originated from the Ural region in today's central Russia and migrated across the Eastern European steppe, according to historical sources. The Hungarians conquered the Carpathian Basin 895-907 AD, and admixed with the indigenous communities. Here we present mitochondrial DNA results from three datasets: one from the Avar period (7(th)-9(th) centuries) of the Carpathian Basin (n = 31); one from the Hungarian conquest-period (n = 76); and a completion of the published 10(th)-12(th) century Hungarian-Slavic contact zone dataset by four samples. We compare these mitochondrial DNA hypervariable segment sequences and haplogroup results with published ancient and modern Eurasian data. Whereas the analyzed Avars represents a certain group of the Avar society that shows East and South European genetic characteristics, the Hungarian conquerors' maternal gene pool is a mixture of West Eurasian and Central and North Eurasian elements. Comprehensively analyzing the results, both the linguistically recorded Finno-Ugric roots and historically documented Turkic and Central Asian influxes had possible genetic imprints in the conquerors' genetic composition. Our data allows a complex series of historic and population genetic events before the formation of the medieval population of the Carpathian Basin, and the maternal genetic continuity between 10(th)-12(th) century and modern Hungarians

Mitochondrial DNA control region analysis of a late neolithic aurochs ( Bos primigenius Boj. 1827) from the Carpathian Basin

Bos primigenius , the wild aurochs is believed to be the ancestor of European domestic cattle, Bos taurus . The geography and climate of the Great Hungarian Plain were well suited for these large grazing animals in the Late Neolithic. Till now, there are just a few aurochs mtDNA fragments available from two geographically restricted area, the British Isles and Italy. To increase our knowledge about the genetics of the European aurochsen livestock, and to investigate the phylogenetic position of a late Neolithic aurochs, excavated from the Carpathian Basin, mitochondrial DNA was extracted from a fragment of corpus mandibulae using ancient-DNA techniques and a portion of mitochondrial hypervariable region was amplified by PCR. The resulting sequence was aligned with GenBank sequences of 11 aurochsen. Our new sequence is identical with the sequence of two British aurochs. The 6000-year-old Hungarian aurochs shows a mtDNA sequence pattern, that occurs only among 6–12,000-year-old North European aurochsen, and it does not occur among modern, domesticated cattle

Mitochondrial DNA of ancient Cumanians: culturally Asian steppe nomadic immigrants with substantially more western Eurasian mitochondrial DNA lineages

The Cumanians were originally Asian pastoral nomads who in the 13th century migrated to Hungary. We have examined mitochondrial DNA from members of the earliest Cumanian population in Hungary from two archeologically well-documented excavations and from 74 modern Hungarians from different rural locations in Hungary. Haplogroups were defined based on HVS I sequences and examinations of haplogroup-associated polymorphic sites of the protein coding region and of HVS II. To exclude contamination, some ancient DNA samples were cloned. A database was created from previously published mtDNA HVS I sequences (representing 2,615 individuals from different Asian and European populations) and 74 modem Hungarian sequences from the present study. This database was used to determine the relationships between the ancient Cumanians, modern Hungarians, and Eurasian populations and to estimate the genetic distances between these populations. We attempted to deduce the genetic trace of the migration of Cumanians. This study is the first ancient DNA characterization of an eastern pastoral nomad population that migrated into Europe. The results indicate that, while still possessing a Central Asian steppe culture, the Cumanians received a large admixture of maternal genes from more westerly populations before arriving in Hungary. A similar dilution of genetic, but not cultural, factors may have accompanied the settlement of other Asian nomads in Europe
