Consequences of O&M 2018 (II): The unsolved nature of Suvorovo-Novodanilovka chiefs, and the route of Proto-Anatolian expansion

This is part 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).

I already expressed my predictions for 2018. One of the most interesting questions among them is the identification of the early Anatolian offshoot, and this is – I believe – where Genomics has the most to say in Indo-European migrations.

Linguistics and Archaeology had already a mainstream account from Late PIE/Yamna onwards, and it has been proven right in Genomic investigation. There is, however, no consensus on Indo-Hittite.

The Indo-European demic diffusion model, and the “R1b – Indo-European” association

Beginning with the new year, I wanted to commit myself to some predictions, as I did last year, even though they constantly change with new data.

I recently read Proto-Indo-European homelands – ancient genetic clues at last?, by Edward Pegler, which is a good summary of the current state of the art in the Indo-European question for many geneticists – and thus a great example of how well Genetics can influence Indo-European studies, and how badly it can be used to interpret actual cultural events – although more time is necessary for some to realize it. Notice for … Read the rest “The Indo-European demic diffusion model, and the “R1b – Indo-European” association”

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”

Archaeological origins of Early Proto-Indo-European in the Baltic during the Mesolithic

New article by Leonid Zaliznyak, Mesolithic origins of the first Indo-European cultures in Europe according to the archaeological data (also available in Russian).

The article refers to the common Meso-Neolithic basis of Ukrainian ancient Indo-European cultures (Mariupol, Serednii Stih) and Central Europe (Funnel Beaker and Globular Amphorae cultures) of the fourth millennium BC. Archaeological materials show that the common cultural and genetic substrate of the earliest Indo-Europeans in Europe was forming from the sixth to the fourth millennia BC due to migration of the Western Baltic Mesolithic population to the east through Poland and Polissia to the Dnipro … Read the rest “Archaeological origins of Early Proto-Indo-European in the Baltic during the Mesolithic”

The new “Indo-European Corded Ware Theory” of David Anthony

I recently wrote about the Indo-European Corded Ware Theory of Kristian Kristiansen and his workgroup, a sort of “Danish school”, whose aim is to prove a direct, long-lasting interaction between the North Pontic steppe and east European cultures during the Late Neolithic, which supposedly gave rise to a Late Indo-European-speaking Corded Ware culture. That is, a sort of renewed Kurgan model; or, more exactly, Kurgan models, since there is no single one preferred right now.

David Anthony had remained more or less in the background after the controversial assessment of the so-called Yamnaya ancestral component by recent … Read the rest “The new “Indo-European Corded Ware Theory” of David Anthony”

Genetic landscapes showing human genetic diversity aligning with geography

New preprint at BioRxiv, Genetic landscapes reveal how human genetic diversity aligns with geography, by Peter, Petkova, and Novembre (2017).

Abstract:

Summarizing spatial patterns in human genetic diversity to understand population history has been a persistent goal for human geneticists. Here, we use a recently developed spatially explicit method to estimate “effective migration” surfaces to visualize how human genetic diversity is geographically structured (the EEMS method). The resulting surfaces are “rugged”, which indicates the relationship between genetic and geographic distance is heterogenous and distorted as a rule. Most prominently, topographic and marine features regularly align with increased genetic
