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 genotypes from Human auditory ossicles as an alternative optimal source of ancient DNA, by Sirak et al. Genome Res. (2020), have been finally published by the Reich Lab, so we can get a sneak peek into what’s coming in future papers about the origins of R1a-rich Proto-Corded Ware and R1b-rich Italo-Venetic peoples.
NOTE. To avoid adding potential errors, I have merged the Reich Lab’s Curated Dataset (v. 42.4, March 1 2020) with these new samples before performing the qpAdm analyses. If you find something different with your files, you should probably check out this simple setting first. … Read the rest “Fully Steppe-like Proto-Corded Ware Late Trypillians”
There has been some renewed interest lately in the origin of Proto-Anatolians, because of the recent lecture by Petra Goedegebuure, associate professor of Hittitology at the University of Chicago: Anatolians on the Move: From Kurgans to Kanesh, given at the Oriental Institute (Feb 5 2020).
I will try to comment on her lecture with a critical view of some of her ideas, keeping in mind reasons for one or the other potential routes, which we can for the moment simplify as Gimbutas’ (1965, 1993) eastern route through the Caucasus vs. Anthony’s (2007, 2015) … Read the rest “Proto-Anatolians: from the Southern Caucasus or the Balkans?”
Another interesting finding from Human auditory ossicles as an alternative optimal source of ancient DNA, by Sirak et al. (2020):
A sample classified as Italy Middle Bronze Age from Olmo di Nogara (ca. 1400-1200 BC), who is R1b-L51 (xP311, xL52, xL151), CTS6889+ (T->C, 1 read). See YFull’s corresponding R-S1161.
This sample probably belongs to individual 309 (35-45 yo), and the female sampled to 323 (30-40 yo), both referenced as from the following study:

Recently, the preprint by Sirak et al. biorXiv (2019), Human auditory ossicles as an alternative optimal source of ancient DNA, was published in Genome Res. (2020), and the corresponding samples were finally uploaded to ENA.
I have been trying to get my hands on sample GLAV_14, a male from the Late Eneolithic site Glăvăneştii Vechi, classified as Romania Bronze Age (ca. 3500-3000 BC), mtDNA T1a1, referenced as investigated first in the study:

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 following are updated files for unsupervised ADMIXTURE of most available ancient Eurasian samples with K=7. For reference, see PCA of ancient and modern Eurasian samples.
NOTE. For a precise interpretation of ancestry evolution, be sure to first check the posts on the expansion of “Steppe ancestry”, on the spread of Yamnaya ancestry with Indo-Europeans, and on the evolution of Corded Ware ancestry typical of modern Uralic populations.
This is a YouTube video similar to the one on Indo-Europeans and Y-DNA evolution:
- I have tried running supervised ADMIXTURE models by selecting

I have compiled for two years now the reported Y-DNA and mtDNA haplogroups of ancient DNA samples published, including also SNPs from analysis of the BAM files by hobbyists.
Here is a video with a timeline of the evolution of Indo-European speakers, according to what is known today about reconstructed languages, prehistoric cultures and ancient DNA:
NOTE. The video is best viewed in HD 1080p (1920×1080) with a display that allows for this or greater video quality, and a screen big enough to see haplogroup symbols, i.e. tablet or greater. The YouTube link is here. The … Read the rest “The expansion of Indo-Europeans in Y-chromosome haplogroups”
New paper (behind paywall) Ancient Rome: A genetic crossroads of Europe and the Mediterranean, by Antonio et al. Science (2019).
The paper offers a lot of interesting data concerning the Roman Empire and more recent periods, but I will focus on Italic and Etruscan origins.
NOTE. I have updated prehistoric maps with Y-DNA and mtDNA data, and also the PCA of ancient Eurasian samples by period including the recently published samples, now with added sample names to find them easily by searching the PDFs.
