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?

Trypillia and Greece Neolithic outliers: the smoking gun of Proto-Anatolian migrations?

neolithic-migrations-khvalynsk-novodanilovka-anatolian

(Continued from the post Corded Ware culture origins: The Final Frontier).

Looking at the PCA of Wang et al. (2018), I realized that Sredni Stog / Corded Ware peoples seem to lie somewhere between:

  • the eastern steppe (i.e. Khvalynsk-Yamna); and
  • Lower Danube and Balkan cultures affected by Anatolian- and steppe-related (i.e. Khvalynsk-Novodanilovka) migrations.

This multiethnic interaction of the western steppe fits therefore the complex archaeological description of events in the North Pontic, Lower Danube, and Dnieper-Dniester regions. Here are some interesting samples related to those long-lasting contacts:

Consequences of O&M 2018 (I): The latest West Yamna “outlier”

This is the first of a series of posts analyzing the findings of the recent Nature papers Olalde et al.(2018) and Mathieson et al.(2018) (abbreviated O&M 2018).

As expected, the first Y-DNA haplogroup of a sample from the North Pontic region (apart from an indigenous European I2 subclade) during its domination by the Yamna culture is of haplogroup R1b-L23, and it is dated ca. 2890-2696 BC. More specifically, it is of Z2103 subclade, the main lineage found to date in Yamna samples. The site in question is Dereivka, “in the southern part of the middle … Read the rest “Consequences of O&M 2018 (I): The latest West Yamna “outlier””

The concept of “Outlier” in Human Ancestry (III): Late Neolithic samples from the Baltic region and origins of the Corded Ware culture

corded-ware-regions-main

I have written before about how the Late Neolithic sample from Zvejnieki seemed to be an outlier among Corded Ware samples (read also the Admixture analysis section on the IEDDM), due to its position in PCA, even more than its admixture components or statistical comparison might show.

In the recent update to Northern European samples in Mittnik et al. (2018), an evaluation of events similar to the previous preprint (2017) is given:

Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the

The concept of “Outlier” in Human Ancestry (II): Early Khvalynsk, Sredni Stog, West Yamna, Iron Age Bulgaria, Potapovka, Andronovo…

yamna-corded-ware-bell-beaker

I already wrote about the concept of outlier in Human Ancestry, so I am not going to repeat myself. This is just an update of “outliers” in recent studies, and their potential origins (here I will repeat some of the examples):

Early Khvalynsk: the three samples from the Samara region have quite different positions in PCA, from nearest to EHG (of Y-DNA haplogroup R1a) to nearest to ANE ancestry (of Y-DNA haplogroup Q). This could represent the initial consequences of the second wave of ANE ancestry – as found later in Yamna samples from a neighbouring region -, … Read the rest “The concept of “Outlier” in Human Ancestry (II): Early Khvalynsk, Sredni Stog, West Yamna, Iron Age Bulgaria, Potapovka, Andronovo…”

The concept of “outlier” in studies of Human Ancestry, and the Corded Ware outlier from Esperstedt

pca-yamna-corded-ware

While writing the third version of the Indo-European demic diffusion model, I noticed that one Corded Ware sample (labelled I0104) clusters quite closely with steppe samples (i.e. Yamna, Afanasevo, and Potapovka). The other Corded Ware samples cluster, as expected, closely with east-central European samples, which include related cultures such as the Swedish Battle Axe, and later Sintashta, or Potapovka (cultures that are from the steppe proper, but are derived from Corded Ware).

I also noticed after publishing the draft that I had used the wording “Corded Ware outlier” at least once. I certainly had that term … Read the rest “The concept of “outlier” in studies of Human Ancestry, and the Corded Ware outlier from Esperstedt”

Proto-Samoyed homeland

siberia-large-samoyed-yukaghir

This post is part of a draft on South Siberian language homelands and Sprachbünde.

The following text contains a description of Pre- and Proto-Samoyedic stages and its dialectal diversification. Contacts with Indo-Iranian, Yeniseian, Tocharian, Yukaghir, and Turkic, as well as onomastics and palaeolinguistics are taken into account to pinpoint the succeeding homelands and expansion territories. The archaeological-archaeogenetic discussion is focused on the Middle Bronze Age Cherkaskul materials of the Andronovo period, on the Late Bronze Age Karasuk culture, and on the evolution and expansion of the Iron Age Tagar culture within the framework of “Scytho-Siberian” … Read the rest “Proto-Samoyed homeland”

Ob-Ugric Homeland

siberia-large-cherkaskul

This post is part of a draft on South Siberian language homelands and Sprachbünde.

The following text contains a description of Ob-Ugric languages and their connection within an Ugric Sprachbund. Special emphasis is placed on their evolution among surrounding ethnolinguistic groups before they were first documented, and on their most likely connection with archaeological cultures succeeding the Seima-Turbino phenomenon in the Southern Urals and the Trans-Urals. The archaeological-archaeogenetic discussion is therefore focused on the Middle Bronze Age Cherkaskul and Late Bronze Age Andronovo-like cultures, as well as on the formation of the “Scythian” Sargat … Read the rest “Ob-Ugric Homeland”

Proto-Yeniseian Homeland

siberia-glazkovo-okunevo-yeniseian

This post is part of a draft on South Siberian language homelands and Sprachbünde.

The following text contains a description of Yeniseian languages, their dialectal groupings and likely evolution among surrounding ethnolinguistic groups before they were first documented. Special emphasis is placed on ancient Yeniseic formants for water bodies, widely distributed through Western, Southern, and Central Siberia. Finally, the archaeological-archaeogenetic discussion is focused on Early Bronze Age Glazkovo-related and Okunevo-like cultures, due to their patrilineal connection to sampled Yeniseian and ancient Na-Dene populations.
