The importance of archaeology before population genomics

early-mesolithic-scandinavia

Recent paper First encounters in the north: cultural diversity and gene flow in Early Mesolithic Scandinavia, by Manninen et al. Antiquity (2021).

The authors criticize the model laid out in Günther et al. (2018), whereby the origin of the previously defined Mesolithic Scandinavian hunter-gatherer genetic group (SHG) was defined as an admixture between genetically defined WHG and EHG populations that migrated into Scandinavia from two separate Ice Age refugia: the south (WHG) and north (EHG). This dualistic model was further associated with two specific lithic blade technologies present in Early Mesolithic Scandinavia (Sørensen et al. 2013), as summarized … Read the rest “The importance of archaeology before population genomics”

Earliest (and basal) haplogroup N-L1026, from East Siberia

baikal-siberia-basal-n-l1026

This is an update to the data from Human population dynamics and Yersinia pestis in ancient northeast Asia, by Kılınç et al. Science Advances (2021).

Files have been released, and some of them are huge, so it might take me some time to analyze them all and include specific subclades in the Ancient DNA Dataset.

For the moment, the sample I highlighted in the previous post, kra001 (2336-2135 calBCE), mtDNA C4b1, from burial Nº1 of Nefteprovod-2, is of very good quality, and it would not be surprising if it made its way to YFull’s tree. It can be … Read the rest “Earliest (and basal) haplogroup N-L1026, from East Siberia”

Vikings, Vikings, Vikings! Hordes of high quality ancient DNA

vikings-admixture-modern

Recent paper (behind paywall) Population genomics of the Viking world, by Margaryan et al. Nature (2020), containing almost exactly the same information as its bioRxiv preprint.

I have used Y-SNP inferences recently reported by FTDNA (see below) to update my Ancient DNA Dataset and the ArcGIS Online Map, and also to examine the chronological and geographical evolution of Y-DNA (alone and in combination with ancestry).

Sections of this post:

  1. Iron Age to Medieval Y-DNA
  2. Iron Age to Medieval Ancestry
  3. Iron Age to Medieval Y-DNA + Ancestry
  4. FTDNA’s big public debut

I. Iron Age to Medieval

Xiongnu Y-DNA connects Huns & Avars to Scytho-Siberians

xiongnu-iron-age-late

Recent paper (behind paywall) Genetic evidence suggests a sense of family, parity and conquest in the Xiongnu Iron Age nomads of Mongolia, by Keyser, Zvénigorosky, Gonzalez, et al. Human Genetics (2020).

Interesting excerpts (emphasis mine):

Site and bodies

The Tamir Ulaan Khoshuu (TUK) cemetery is located near the confluence of the Tamir River and the Orkhon River in the Arkhangai Aimag (Central Mongolia), about four hundred kilometers west of the capital of Mongolia, Ulaanbaatar. It encompasses an area of 22 hectares located on a prominent granitic outcrop and comprises a total of 397 graves, delimited by stone circles. (…)

N-Z1936 thrived around the Urals in the Middle Ages

magna-hungaria-magyar-expansion

New preprint Early Medieval Genetic Data from Ural Region Evaluated in the Light of Archaeological Evidence of Ancient Hungarians, by Csaky et al. bioRxiv (2020).

Interesting excerpts (emphasis mine):

Based on linguistic evidences, the Hungarian language, belonging to the Ugric branch of the Uralic language family, was developed at the eastern side of Ural Mountains between 1000-500 BC. According to the written and linguistic sources and archaeological arguments, after the 6th century AD, part of the predecessors of Hungarians moved to the Western Urals (Cis-Ural region) from their ancient homeland. Around the first third of 9th century

Demic vs. cultural diffusion and patrilineal Megalithic societies

neolithic-expansion-map

Recent paper A dynastic elite in monumental Neolithic society, by Cassidy et al. Nature (2020) 582:384–388.

Interesting excerpts (emphasis mine):

Neolithic Admixture

We sampled remains from all of the major Irish Neolithic funerary traditions: court tombs, portal tombs, passage tombs, Linkardstown-type burials and natural sites. Within this dataset, the earliest Neolithic human remains from the island—interred at Poulnabrone portal tomb14—are of majority ‘Early_Farmer’ ancestry (as defined by ADMIXTURE modelling), and show no evidence of inbreeding, which implies that, from the very onset, agriculture was accompanied by large-scale maritime colonization. Our ADMIXTURE and ChromoPainter analyses do not distinguish between

Online GIS maps of ancient Y-DNA, mtDNA and ADMIXTURE

arcgis-online-y-dna

The last few weeks have been very exciting in terms the amount, diversity and quality of newly reported ancient samples, which included new genotypes and also Y-DNA and mtDNA haplogroups.

As some of you already know, I had been preparing a tailored GIS map of ancient DNA using QGIS-server on Ubuntu and trying some of the available plugins for the task, and was ready to use my old broken PC as a web server. For that, I needed to prepare different files corresponding to the different conventional divisions of the Prehistory Atlas. The crazy number of recently reported papers … Read the rest “Online GIS maps of ancient Y-DNA, mtDNA and ADMIXTURE”

Afanasievo ancestry reached Lake Baikal; Nganasan ancestry origins still at large

baikal-neolithic-eba-ane-nea

New paper (behind paywall) Paleolithic to Bronze Age Siberians Reveal Connections with First Americans and across Eurasia, by Yu et al. Cell (2020)

Interesting excerpts (emphasis mine, paragraphs subdivided for clarity):

Population Structure (PCA)

Most of the Lake Baikal individuals occupied the space on a “ANE-NEA” cline running between “Northeast Asian” (NEA) ancestry represented by Neolithic hunter-gathers from the Devil’s Gate in the Russian Far East (Sikora et al., 2019, Siska et al., 2017), and the ANE ancestry represented by Upper Paleolithic Siberian individuals MA1, AfontovaGora 2 (AG2), and AfontovaGora 3 (AG3) (Fu et al., 2016, Raghavan et al.,

R1b-rich Proto-Indo-Europeans show genetic continuity in Asia

middle-bronze-age-andronovo-horizon

Another preprint came out at the same time as Wang et al. (2020), from the Jena Lab of the Max Planck Society: A dynamic 6,000-year genetic history of Eurasia’s Eastern Steppe, by Jeong, Warinner, et al. bioRxiv (2020).

NOTE. I have now updated the Ancient DNA Dataset, the Prehistory Atlas – with PDF and GIS files including Y-DNA and mtDNA of all newly reported samples (starting with the Neolithic) – as well as the PCA files with those from Wang et al. (2020).

The conclusions are similar, but with some interesting twists. Relevant excerpts (emphasis mine), … Read the rest “R1b-rich Proto-Indo-Europeans show genetic continuity in Asia”
