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”
Now that it has become evident that Late Repin (i.e. Yamnaya/Afanasevo) ancestry was associated with the migration of R1b-L23-rich Late Proto-Indo-Europeans from the steppe in the second half of the the 4th millennium BC, there’s still the question of how R1a-rich Uralic speakers of Corded Ware ancestry expanded , and how they spread their languages throughout North Eurasia.
Modern North Eurasians
I have been collecting information from the supplementary data of the latest papers on modern and ancient North Eurasian peoples, including Jeong et al. (2019), Saag et al. (2019), Sikora et al. (2018), or … Read the rest “Corded Ware ancestry in North Eurasia and the Uralic expansion”
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 (behind paywall) Origins of equine dentistry, by Taylor et al. PNAS (2018).
Interesting excerpts (emphasis mine):
The practice of horse dentistry by contemporary nomadic peoples in Mongolia, coupled with the centrality of horse transport to Mongolian life, both now and in antiquity, raises the possibility that dental care played an important role in the development of nomadic life and domestic horse use in the past. To investigate, we conducted a detailed archaeozoological study of horse remains from tombs and ritual horse inhumations across the Mongolian Steppe, assessing evidence for anthropogenic dental modifications and comparing our findings

New open access paper from the Max Planck Institute: Analysis of 3800-year-old Yersinia pestis genomes suggests Bronze Age origin for bubonic plague, by Spyrou et al., Nature Communications (2018) 9:2234.
Interesting excerpts from the paper and supplementary materials (emphasis mine):
Here, we analyse material from the Mikhailovsky II burial site, which was excavated in 2015 and is one of numerous kurgan cemeteries identified in the Samara Oblast. It consists of seven kurgan burials, and is chronologically associated to the ‘Pokrovka’ phase (3,900-3,750 BP) of the ‘Srubnaya’ culture (3,850-3,150 BP) (radiocarbon dates produced in this study provided in Supplementary Table

Henny Piezonka recently uploaded an old chapter, Die frühe Keramik Eurasiens: Aktuelle Forschungsfragen und methodische Ansätze, in Multidisciplinary approach to archaeology: Recent achievements and prospects. Proceedings of the International Symposium “Multidisciplinary approach to archaeology: Recent achievements and prospects”, June 22-26, 2015, Novosibirsk, Eds. V. I. Molodin, S. Hansen.
Abstract (in German):
Die älteste bisher bekannte Gefäßkeramik der Welt wurde in Südostchina von spätglazialen Jäger-Sammlern wahrscheinlich schon um 18.000 cal BC hergestellt. In den folgenden Jahrtausenden verbreitete sich die neue Technik bei Wildbeutergemeinschaften in der russischen Amur-Region, in Japan, Korea und Transbaikalien bekannt, bevor sie im frühen und mittleren

Reconstructing the demographic history of the Himalayan and adjoining populations, by Tamang, R., Chaubey, G., Nandan, A. et al. Hum Genet (2018).
Abstract (emphasis mine):
The rugged topography of the Himalayan region has hindered large-scale human migrations, population admixture and assimilation. Such complexity in geographical structure might have facilitated the existence of several small isolated communities in this region. We have genotyped about 850,000 autosomal markers among 35 individuals belonging to the four major populations inhabiting the Himalaya and adjoining regions. In addition, we have genotyped 794 individuals belonging to 16 ethnic groups from the same region, for uniparental
