За аланите и техните кавказки наследници

От около 1:30:00 се разказва за генетичните изследвания (нови и стари), но на мен ми беше интересна цялата лекция и затова я споделям. Smile
И като цяло, в каналът "Центр Архэ" има доста интересна информация.
Благодаря, много интересно Smile
Аланите бяха доизследвани и са повечето G2a, както R1a-Z94, Q1а и J1. Намерен е май само един J2a.

In 2015 the Institute of Archaeology in Moscow conducted research on various Sarmato-Alan and Saltovo-Mayaki culture Kurgan burials. In this analysis, the two Alan samples from the 4th to 6th century CE had yDNAs G2a-P15 and R1a-z94, while from the three Sarmatian samples from 2nd to 3rd century CE two had yDNA J1-M267 and one possessed R1a.[75] Also, the three Saltovo-Mayaki samples from 8th to 9th century CE turned out to have yDNAs G, J2a-M410 and R1a-z94 respectively.[76]

A genetic study published in Nature in May 2018 examined the remains of six Alans buried in the Caucasus from ca. 100 CE to 1400 CE. The sample of Y-DNA extracted belonged to haplogroup R1 and haplogroup Q-M242. One of the Q-M242 samples found in Beslan, North Ossetia from 200 CE found 4 relatives among Chechens from the Shoanoy Teip.[77] The samples of mtDNA extracted belonged to HV2a1, U4d3, X2f, H13a2c, H5, and W1.

Изглежда предстои да излезе ново руско изследване за аланите, този път и по аутозомни данни от 70 индивида 3-13 в. от Северен Кавказ.

Ancient DNA analysis of Early Medieval Alan populations of the North Caucasus
Content:The earliest existing written evidence about Alans – people of Ponto-Caspian steppes and Caucasus region of I-XIII century AD – is found in the works of Chinese authors who mention the politonym "Yancai" in the "Records of the Grand Historian" and in the "History of the Former Han", and of European antique authors in the middle of the 1st century AD.
Genetic data of the early Middle Ages Alans and their affinities to the Scythian-Sarmatian tribes, traditionally considered as their ancestors, as well as to the modern population of Europe and the Caucasus have not yet studied thoroughly, the whole genome data exists for only 6 individuals [1].

In this study we have analyzed ancient DNA of 70 individuals from 12 burial complexes belonging to the Alan culture from the III-XIII century AD, from the territory of the North Caucasus (Russian Federation). DNA was extracted from the archaeological material (teeth, temporal bone) of 70 individuals. We produced low-coverage Illumina whole-genome shotgun sequencing data for 63 individuals and will analyze these in a context of ancient and modern genetic variation of the region. The coverage of the genomes was 0.0004-0.3X (median coverage 0.045X and content of endogenous DNA 21,45%).
To analyze changes in the gene pool we divided our sample into early (III-VIII AD) and late Alans (VIII-XIII AD). The Y-chromosomal palette of Alans consisting of 6 different haplogroups (R, Q, J, I,G, E) started to be similar to that of present day autochthonous North Caucasus populations only in the later phase of Alan culture.
The preliminary analysis allows us to assume close contacts of the Alans with the populations of the North Caucasus.
The distribution of mitochondrial haplogroups in early and late Alans has insignificant differences, while in both groups the East Eurasian component is approximately the same.
PCA analysis is consistent with the results of the obtained haplogroups of both mtDNA and Y-chromosomes. Studied Alan groups can be characterized as genetically heterogeneous, most of the samples are close to the modern populations of the North Caucasus, and some of the samples show an admixture of the East Asian component or a connection with the populations of the Volga-Ural region.
It can be assumed that the late Alans were partially assimilated by the populations of the North Caucasus, while both the early and late Alans had long and close contacts with the East Eurasian populations, which may also be associated with the route of the Great Silk Road through the Caucasus.
