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”
New preprint by the Jena-Reich labs, The Genomic Formation of Human Populations in East Asia, by Wang et al. bioRxiv (2020).
Interesting excerpts (emphasis mine):
Mongolia Neolithic cluster
The three most ancient individuals of the Mongolia ‘East’ cluster are from the Kherlen River region of eastern Mongolia (Tamsag-Bulag culture) and date to 6000-4300 BCE (this places them in the Early Neolithic period, which in Northeast Asia is defined by the use of pottery and not by agriculture). These individuals are genetically similar to previously reported Neolithic individuals from the cis-Baikal region and have minimal evidence of West Eurasian-related admixture

The previous post showed the potential use of TreeToM to visualize ancient DNA samples in maps together with their Y-DNA phylogenetic trees. I have written Newick trees for Y-chromosome haplogroups R1b-L388 (encompassing R-V1636 and R-P297, which in turn split into R-M73 and R-M269), R1a, and N.
I have reviewed some of the BAM files from my previous bulk analyses with YLeaf v.2, to add information that I had not previously included in the All Ancient DNA Dataset, and which might be relevant to the proper depiction of phylogenetic trees; in particular, positive and negative SNPs potentially distinguishing archaic… Read the rest “Ancient phylogeography: spread of haplogroups R1b, R1a and N”
The latest papers from Ning et al. Cell (2019) and Anthony JIES (2019) have offered some interesting new data, supporting once more what could be inferred since 2015, and what was evident in population genomics since 2017: that Proto-Indo-Europeans expanded under R1b bottlenecks, and that the so-called “Steppe ancestry” referred to two different components, one – Yamnaya or Steppe_EMBA ancestry – expanding with Proto-Indo-Europeans, and the other one – Corded Ware or Steppe_MLBA ancestry – expanding with Uralic speakers.
The following maps are based on formal stats published in the papers and supplementary materials from 2015 until today, mainly on … Read the rest “Yamnaya ancestry: mapping the Proto-Indo-European expansions”
Open access Y-chromosomal connection between Hungarians and geographically distant populations of the Ural Mountain region and West Siberia, by Post et al. Scientific Reports (2019) 9:7786.
More interesting than the study of modern populations of the paper is the following excerpt from the introduction, referring to a paper that is likely in preparation, Európai És Ázsiai Apai Genetikai Vonalak A Honfoglaló Magyar Törzsekben, by Fóthi, E., Fehér, T., Fóthi, Á. & Keyser, C., Avicenna Institute of Middle Eastern Studies (2019):

Second in popularity for the expansion of haplogroup N1a-L392 (ca. 4400 BC) is, apparently, the association with Turkic, and by extension with Micro-Altaic, after the Uralic link preferred in Europe; at least among certain eastern researchers.
New paper in a recently created journal, by the same main author of the group proposing that Scythians of hg. N1c were Turkic speakers: On the origins of the Sakhas’ paternal lineages: Reconciliation of population genetic / ancient DNA data, archaeological findings and historical narratives, by Tikhonov, Gurkan, Demirdov, and Beyoglu, Siberian Research (2019).

Recently, a paper described Eastern Scythian groups as “Uralic-Altaic” just because of the appearance of haplogroup N in two Pazyryk samples.
This simplistic identification is contested by the varied haplogroups found in early Altaic groups, by the early link of Cimmerians with the expansion of hg. N and Q, by the link of N1c-L392 in north-eastern Europe with Palaeo-Laplandic, and now (paradoxically) by the clear link between early Mongolic expansion and N1c-L392 subclades.
A new paper (behind paywall) offers insight into the prevalent presence of R1a-Z93 among eastern Scytho-Siberian groups (most likely including Samoyedic speakers in … Read the rest “Scytho-Siberians of Aldy-Bel and Sagly, of haplogroup R1a-Z93, Q1b-L54, and N”

Avars of haplogroup N1c-Tat
Preprint Genetic insights into the social organisation of the Avar period elite in the 7th century AD Carpathian Basin, by Csáky et al. bioRxiv (2019).
Interesting excerpts (emphasis mine):
After 568 AD the Avars settled in the Carpathian Basin and founded the Avar Qaganate that was an important power in Central Europe until the 9th century. Part of the Avar society was probably of Asian origin, however the localisation of their homeland is hampered by the scarcity of historical and archaeological
