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

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

Recent archaeological finds near Indo-European and Uralic homelands

The latest publication of Documenta Praehistorica, vol. 44 (2017) is a delight for anyone interested in Indo-European and Uralic studies, whether from a linguistic, archaeological, anthropological, or genetic point of view. Articles are freely downloadable from the website.

The following is a selection of articles I deem more interesting, but almost all are.

On the Corded Ware culture

Do 14C dates always turn into an absolute chronology? The case of the Middle Neolithic in western Lesser Poland, by Marek Novak:

In the late 5th, 4th, and early 3rd millennia BC, different archaeological units are visible in western Lesser

Eneolithic Ukraine cultures of the North Pontic steppe and southern steppe-forest, on the Left Bank of the Dnieper

As I said before, Yuri Rassamakin is one archaeologist to follow closely for those interested in Neolithic and Chalcolithic Ukraine (ca. 5000-3300 BC), including Sredni Stog, and their potential connection with the Corded Ware culture, as well as the later expansion of Yamna into the region (and Yamna settlers into south-eastern Europe).

His recent studies include important sites (for Archaeology and recently also for Genomics) such us Dereivka and Alexandria, part of the North Pontic steppe and southern steppe-forest zone, on the Left Bank of the Dnieper river. According to him, many of these … Read the rest “Eneolithic Ukraine cultures of the North Pontic steppe and southern steppe-forest, on the Left Bank of the Dnieper”

Differences in ADMIXTURE between Khvalynsk/Yamna and Sredni Stog/Corded Ware

Looking for differences among steppe cultures in Genomics is like looking for a needle in a haystack.

It means, after all, looking for differences among closely related cultures, such as between South-Western and North-Western Anatolian Neolithic cultures, or among Old European cultures (such as Vinča or Cucuteni–Trypillia), or between Iberian cultures after the arrival of steppe-related populations.

These differences between closely related regions, in all these cases and especially among steppe cultures, even when they are supported by Archaeology and anthropological models of migration (and compatible with linguistic models), are expected to be minimal.

Fortunately, we have … Read the rest “Differences in ADMIXTURE between Khvalynsk/Yamna and Sredni Stog/Corded Ware”

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

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…”

New Ukraine Eneolithic sample from late Sredni Stog, near homeland of the Corded Ware culture

Just one day after publishing the draft of the Indo-European demic diffusion model, 3rd version, Mathieson et al. (2017) have updated some information in a new version of their article, including a new interesting sample from late Sredni Stog. It gives support to what I predicted, regarding the potential origin of the third Corded Ware horizon.

After my first version, findings in Olalde et al. (2017) and Mathieson et al. (2017) supported some of my predictions. Now after my third, their new data also supports another prediction. Because the model is based on solid linguistic … Read the rest “New Ukraine Eneolithic sample from late Sredni Stog, near homeland of the Corded Ware culture”
