Indo-European demic diffusion model, 3rd Ed. – Revised October 2017

pca-yamna-corded-ware

I have just uploaded a new working draft of the third version of the Indo-European demic diffusion model.

In this new version I have added more information published recently, I have updated the maps – especially the one on Palaeolithic migrations -, I have added information on Sredni Stog and its potential role in developing the Corded Ware culture and most likely language, and I have corrected certain parts that have become obsolete, especially after the latest version (19 Sept. 2017) of Mathieson et al. (2017).

The Tollense Valley battlefield: the North European ‘Trojan war’ that hints to western Balto-Slavic origins

bronze-age-tollense-battle

It was reported long ago that genetic studies were being made on remains of a surprisingly big battle that happened in the Tollense valley in north-eastern Germany, at the confluence between Nordic, Tumulus/Urnfield, and Proto-Lusatian/Lusatian territories, ca. 1200 BC.

At least 130 bodies and 5 horses have been identified from the bones found. Taking into account that this is a small percentage of the potential battlefield, around 750 bodies are expected to be buried in the riverbank, so an estimated 4,000-strong army fought there, accounting for one in five participants killed and left on the battlefield.

Body armour, … Read the rest “The Tollense Valley battlefield: the North European ‘Trojan war’ that hints to western Balto-Slavic origins”

Forces driving grammatical change are different to those driving lexical change

Grammar change

A new paper at PNAS, Evolutionary dynamics of language systems, by Greenhill et al. (2017).

Significance

Do different aspects of language evolve in different ways? Here, we infer the rates of change in lexical and grammatical data from 81 languages of the Pacific. We show that, in general, grammatical features tend to change faster and have higher amounts of conflicting signal than basic vocabulary. We suggest that subsystems of language show differing patterns of dynamics and propose that modeling this rate variation may allow us to extract more signal, and thus trace language history deeper than has been previously

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

eneolithic-europe

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”

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”

Indo-European demic diffusion model, 3rd edition

pca-yamna-corded-ware

I have just uploaded the working draft of the third version of the Indo-European demic diffusion model. Unlike the previous two versions, which were published as essays (fully developed papers), this new version adds more information on human admixture, and probably needs important corrections before a definitive edition can be published.

The third version is available right now on ResearchGate and Academia.edu. I will post the PDF at Academia Prisca, as soon as possible:

Marija Gimbutas and the expansion of the “Kurgan people” based on tumulus-building cultures

kurgan-expansion

An interesting article that I keep stumbling upon, The tumulus in European prehistory: covering the body, housing the soul, by Anthony Harding (2011):

Finally, in Kurgan IV she saw “continuous waves of expansion or raids[that] touched all of northern Europe, the Aegean area, and the east Mediterranean areas possibly as far south as Egypt”. This was the period of the Catacomb Graves, but also the Early Bronze Age rock-cut tombs of the Mediterranean, Vučedol, Bell Beakers in Hungary, the Single Grave culture of the Nordic region. The Kurgan Culture reached Ireland, she remarked in a paper of 1978 “as

Something is very wrong with models based on the so-called ‘steppe admixture’ – and archaeologists are catching up

steppe-admixture

Russian archaeologist Leo Klejn has published an article Discussion: Are the Origins of Indo-European Languages Explained by the Migration of the Yamnaya Culture to the West?, which includes the criticism received from Wolfgang Haak, Iosif Lazaridis, Nick Patterson, and David Reich (mainly on the genetic aspect), and from Kristian Kristiansen, Karl-Göran Sjögren, Morten Allentoft, Martin Sikora, and Eske Willerslev (mainly on the archaeological aspect).

I will not post details of Klejn’s model of North-South Proto-Indo-European expansion – which is explained in the article, and relies on the north-south cline of ‘steppe admixture’ in the modern European population -, since … Read the rest “Something is very wrong with models based on the so-called ‘steppe admixture’ – and archaeologists are catching up”

How to do modern phylogeography: Relationships between clans and genetic kin explain cultural similarities over vast distances

yakut-phylogeography

A preprint paper has been published in BioRxiv, Relationships between clans and genetic kin explain cultural similarities over vast distances: the case of Yakutia, by Zvenigorosky et al (2017).

Abstract:

Archaeological studies sample ancient human populations one site at a time, often limited to a fraction of the regions and periods occupied by a given group. While this bias is known and discussed in the literature, few model populations span areas as large and unforgiving as the Yakuts of Eastern Siberia. We systematically surveyed 31,000 square kilometres in the Sakha Republic (Yakutia) and completed the archaeological study of 174
