Italo-Venetic peoples related patrilineally to Terramare elites

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.

SNP inference for I18130(9309_Oss) / I18131(9309_Co)

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:

Earliest R1a-Z93…from Late Trypillia in the Podolian-Volhynian Upland!

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:

Ancient phylogeography: spread of haplogroups R1b, R1a and N

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”

Visualizing phylogenetic trees of ancient DNA in a map

Yesterday the Eaton Lab at Columbia University announced on Twitter a nifty little tool by Carlos Alonso Maya-Lastra called TreeToM, which accepts Newick trees and CSV latitude/longitude data to explore phylogeny and geography interactively, with no coding required.

I thought it could complement nicely my All Ancient DNA Dataset, particularly for those newly described SNPs (FTDNA private variants, etc.) that have not been incorporated yet into SNP Tracker.

Here are two examples with snippets to copy&paste to the appropriate boxes in TreeToM. Feel free to add others in the comments:… Read the rest “Visualizing phylogenetic trees of ancient DNA in a map”

Early Uralic – Indo-European contacts within Europe

One of the most interesting aspects for future linguistic research, boosted by the current knowledge in population genomics, is the influence of Uralic – most likely spread initially with Corded Ware peoples across northern Europe – on early Indo-European dialects.

Whereas studies on the potential Afroasiatic (or Semitic), Vasconic, Etruscan, or non-Indo-European in general abound for ancient and southern IE branches (see e.g. more on the NWIE substrate words), almost exclusively Uralicists have dealt with the long-term mutual influences between Indo-European and Uralic dialects, and often mostly from the Uralic side.… Read the rest “Early Uralic – Indo-European contacts within Europe”

Spread of Indo-European and Uralic speakers in ADMIXTURE

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.

Intense but irregular NWIE and Indo-Iranian contacts show Uralic disintegrated in the West

Open access PhD thesis Indo-Iranian borrowings in Uralic: Critical overview of sound substitutions and distribution criterion, by Sampsa Holopainen, University of Helsinki (2019), under the supervision of Forsberg, Saarikivi, and Kallio.

The gap between Russian and Western scholarship

Many scholars in the Soviet Union and later the Russian Federation also have researched this topic over the last five decades. Notably the eminent Eugene Helimski dealt with this topic in several articles: his 1992 article (republished in Helimski 2000) on the emergence of Uralic consonantal stems used Indo-Iranian and other Indo-European loans as key evidence, and

Samoyedic shows Yeniseic substrate; both influenced Tocharian

Open access paper The deviant typological profile of the Tocharian branch of Indo-European may be due to Uralic substrate influence by Peyrot, Indo-European Linguistics (2019).

NOTE. This seems to be part of the master’s thesis by Abel Warries, but the paper is authored only by Peyrot.

Interesting excerpts (emphasis mine):

1. The stop system

The loss in Tocharian of the Proto-Indo-European obstruent distinctions conventionally noted as voice and aspiration is a very strong indication of foreign influence. Since Proto-Indo-European roots mostly have at least one stop, and often two, the merger of all three stop series into one must have

The expansion of Indo-Europeans in Y-chromosome haplogroups

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.

Y-DNA timeline

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”
