Another “Pre-Yamnaya” sample from the Northern Caucasus?

wang-caucasus-maykop

I have updated the Ancient DNA Dataset, including a lot of new information from – among other sources – the latest version of Reich Lab curated Dataset, now renamed Allen Ancient DNA Resource (AADR). This includes new columns:

  1. Object-ID: I am now using whenever possible the Master-ID; Version-ID for a quick identification of the ‘best’ sample to include in SmartPCA or ADMIXTURE runs; and Index as a key with a unique reference number for each sample. That should make for enough stable references for any external tool to use the data.
  2. mtDNA: Added mtDNA coverage

Proto-Indo-Europeans: A family business

khvalynsk-yamnaya-y-dna-bottleneck

I have been updating the Ancient DNA Dataset with date estimates published in the recent preprint by Sedig, Olalde, Patterson & Reich bioRxiv (2020), and it had a reference to some interesting new samples from Khvalynsk, showing tight family connections.

Information below is taken from the preprint and from the latest version of the Reich Lab’s Allen Ancient DNA Resource (AADR). Information about the three published Khvalynsk samples is taken from Mathieson et al. Nature (2015) supplementary materials, and each ID features a different font color in the text below for clarity’s sake.

Proto-Uralic Homeland (VIII): Earliest External Contacts

bandtoepfer-donau
< PreviousNext >

This post is part of a draft on palaeolinguistics and the Proto-Uralic homeland. See below for the color code of protoforms.

14. Earliest PU ~ PIE contacts

14.1. Indo-Uralic?

The most reliable correspondences to propose an Indo-Uralic phylum come from basic morphological comparisons. Some of the most frequently mentioned ones include (e.g. Čop 1975, Kortlandt 2002, Bjørn 2019, or Lubotsky 2019):

  • Nominal endings:
  • PU nom.sg. *-Ø ~ PIA nom.-acc.sg. *-Ø (in neuter athematic nouns).
  • PU acc.sg. *-m ~ PIA acc.sg. *-m.
  • PU dual *-ki(-) ~ PIA nom.-acc.du. *-h₁.
  • PU abl. *-tA ~

Proto-Anatolians: from the Southern Caucasus or the Balkans?

anatolian-lba-kingdoms-hatti

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?”

“Steppe ancestry” step by step (2019): Mesolithic to Early Bronze Age Eurasia

yamnaya-gac-maykop-corded-ware-bell-beaker

The recent update on the Indo-Anatolian homeland in the Middle Volga region and its evolution as the Indo-Tocharian homeland in the Don–Volga area as described in Anthony (2019) has, at last, a strong scientific foundation, as it relies on previous linguistic and archaeological theories, now coupled with ancient phylogeography and genomic ancestry.

There are still some inconsistencies in the interpretation of the so-called “Steppe ancestry”, though, despite the one and a half years that have passed since we first had access to the closest Pontic–Caspian steppe source populations. Even my post “Steppe ancestry” step by step from a year ago … Read the rest ““Steppe ancestry” step by step (2019): Mesolithic to Early Bronze Age Eurasia”

Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe

eba-yamnaya-ancestry-hungary

I have recently written about the spread of Pre-Yamnaya or Yamnaya ancestry and Corded Ware-related ancestry throughout Eurasia, using exclusively analyses published by professional geneticists, and filling in the gaps and contradictory data with the most reasonable interpretations. I did so consciously, to avoid any suspicion that I was interspersing my own data or cherry picking results.

Now I’m finished recapitulating the known public data, and the only way forward is the assessment of these populations using the available datasets and free tools.

Understanding the complexities of qpAdm is fairly difficult without a proper genetic and statistical background, which I … Read the rest “Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe”

On the Ukraine Eneolithic outlier I6561 from Alexandria

sredni-stog-eneolithic-late

Over the past week or so, since the publication of new Corded Ware samples in Narasimhan, Patterson et al. (2019) and after finding out that the R1a-M417 star-like phylogeny may have started ca. 3000 BC, I have been ruminating the relevance of contradictory data about the Ukraine_Eneolithic_o sample from Alexandria, its potential wrong radiocarbon date, and its implications for the Indo-European question.

How many other similar ‘controversial’ samples are there which we haven’t even considered? And what mechanisms are in place to control that the case of Hajji_Firuz_CA I2327 is not repeated?

Yamnaya ancestry: mapping the Proto-Indo-European expansions

steppe-ancestry-expansion-europe

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”

Volga Basin R1b-rich Proto-Indo-Europeans of (Pre-)Yamnaya ancestry

yamnaya-expansion

New paper (behind paywall) by David Anthony, Archaeology, Genetics, and Language in the Steppes: A Comment on Bomhard, complementing in a favourable way Bomhard’s Caucasian substrate hypothesis in the current issue of the JIES.

NOTE. I have tried to access this issue for some days, but it’s just not indexed in my university library online service (ProQuest) yet. This particular paper is on Academia.edu, though, as are Bomhard’s papers on this issue in his site.

Interesting excerpts (emphasis mine):

Along the banks of the lower Volga many excavated hunting-fishing camp sites are dated 6200-4500 BC. They
