Proto-Indo-European homeland south of the Caucasus?

User Camulogène Rix at Anthrogenica posted an interesting excerpt of Reich’s new book in a thread on ancient DNA studies in the news (emphasis mine):

Ancient DNA available from this time in Anatolia shows no evidence of steppe ancestry similar to that in the Yamnaya (although the evidence here is circumstantial as no ancient DNA from the Hittites themselves has yet been published). This suggests to me that the most likely location of the population that first spoke an Indo-European language was south of the Caucasus Mountains, perhaps in present-day Iran or Armenia, because ancient DNA from people who

Distribution of Southern Iberian haplogroup H indicates exchanges in the western Mediterranean

Recent open access paper The distribution of mitochondrial DNA haplogroup H in southern Iberia indicates ancient human genetic exchanges along the western edge of the Mediterranean, by Hernández, Dugoujon, Novelletto, Rodríguez, Cuesta and Calderón, BMC Genetics (2017).

Abstract (emphasis mine):

Background
The structure of haplogroup H reveals significant differences between the western and eastern edges of the Mediterranean, as well as between the northern and southern regions. Human populations along the westernmost Mediterranean coasts, which were settled by individuals from two continents separated by a relatively narrow body of water, show the highest frequencies of mitochondrial haplogroup H. These

Y-DNA haplogroup R1b-Z2103 in Proto-Indo-Iranians?

chalcolithic_early-asia

We already know that the Sintashta -Andronovo migrants will probably be dominated by Y-DNA R1a-Z93 lineages. However, I doubt it will be the only Y-DNA haplogroup found.

I said in my predictions for this year that there could not be much new genetic data to ascertain how Pre-Indo-Iranian survived the invasion, gradual replacement and founder effects that happened in terms of male haplogroups after the arrival of late Corded Ware migrants, and that we should probably have to rely on anthropological explanations for language continuity despite genetic replacement, as in the Basque case.

Nevertheless, since … Read the rest “Y-DNA haplogroup R1b-Z2103 in Proto-Indo-Iranians?”

Mixed haplogroups R1a, R1b, I, in collective burials of early Medieval Bavarians

antiquity-europe

New paper (behind paywall) Family graves? The genetics of collective burials in early medieval southern Germany on trial, by Rott. Päffgen, Haas-Gebhard, Peters, & Harbecka, J Arch Sci (2018) 92: 103–115.

Abstract:

Simultaneous collective burials appear quite regularly in early medieval linear cemeteries. Despite their relatively regular occurrence, they are seen as extraordinary as the interred individuals’ right to be buried in a single grave was ignored for certain reasons. Here, we present a study examining the possible familial relationship of early medieval individuals buried in this way by using aDNA analysis of mitochondrial HVR-I, Y-STRs, and autosomal miniSTRs.

North Pontic steppe Eneolithic cultures, and an alternative Indo-Slavonic model

I am not a fan of continuity theories – that much should be clear for anyone reading this blog. However, most of such proposals’ supremacist (or rather fear-of-inferiority) overtones don’t mean they have to be wrong. It just means that most of them, most of the time, most likely are.

While reading Tommenable’s comments, I thought about a potential alternative model, where one could a priori accept an identification of North Pontic cultures as ‘Indo-Slavonic’, which seems to be the Eastern European R1a continuist trend right now.

NOTE. To accept this model, one should first (… Read the rest “North Pontic steppe Eneolithic cultures, and an alternative Indo-Slavonic model”

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””

Olalde et al. and Mathieson et al. (Nature 2018): R1b-L23 dominates Bell Beaker and Yamna, R1a-M417 resurges in East-Central Europe during the Bronze Age

The official papers Olalde et al. (Nature 2018) and Mathieson et al. (Nature 2018) have appeared. They are based on the 2017 preprints at BioRxiv The Beaker Phenomenon And The Genomic Transformation Of Northwest Europe and The Genomic History Of Southeastern Europe respectively, but with a sizeable number of new samples.

Papers are behind a paywall, but here are the authors’ shareable links to read the papers and supplementary materials: Olalde et al. (2018), Mathieson et al. (2018).

NOTE: The corresponding datasets have been added to the Reich Lab website. Remember you can use my drafts on … Read the rest “Olalde et al. and Mathieson et al. (Nature 2018): R1b-L23 dominates Bell Beaker and Yamna, R1a-M417 resurges in East-Central Europe during the Bronze Age”

First Hungarian ruling dynasty, the Árpáds, of Y-DNA haplogroup R1a

middle-ages-europe

Open access article DNA profiling of Hungarian King Béla III and other skeletal remains originating from the Royal Basilica of Székesfehérvár, Olasz, J., Seidenberg, V., Hummel, S. et al. Archaeol Anthropol Sci (2018).

Abstract

A few decades after the collapse of the Avar Khaganate (c. 822 AD), Hungarian invaders conquered the Carpathian Basin (c. 862–895 AD). The first Hungarian ruling dynasty, the Árpáds played an important role in European history during the Middle Ages. King Béla III (1172–1196) was one of the most significant rulers of the dynasty. He also consolidated Hungarian dominance over the Northern Balkans. The

R1b-V88 migration through Southern Italy into Green Sahara corridor, and the Afroasiatic connection

palaeolithic

Open access article The peopling of the last Green Sahara revealed by high-coverage resequencing of trans-Saharan patrilineages, by D’Atanasio, Trombetta, Bonito, et al., Genome Biology (2018) 19:20.

Abstract:

Background
Little is known about the peopling of the Sahara during the Holocene climatic optimum, when the desert was replaced by a fertile environment.

Results
In order to investigate the role of the last Green Sahara in the peopling of Africa, we deep-sequence the whole non-repetitive portion of the Y chromosome in 104 males selected as representative of haplogroups which are currently found to the north and to the south of
