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


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.


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.

A history of male migration in and out of the Green Sahara

Open access research highlight A history of male migration in and out of the Green Sahara, by Yali Xue, Genome Biology (2018) 19:30, on the recent paper by D’Atanasio et al.

Insights from the Green Saharan Y-chromosomal findings (emphasis mine):

It is widely accepted that sub-Saharan Y chromosomes are dominated by E-M2 lineages carried by Bantu-speaking farmers as they expanded from West Africa starting <  5 kya, reaching South Africa within recent centuries [4]. The E-M2-Bantu lineages lie phylogenetically within the E-M2-Green Sahara lineage and show at least three explosive lineage expansions beginning 4.9–5.3 kya [5] (Fig. 1a). These events of

David Reich on the influence of ancient DNA on Archaeology and Linguistics

An interesting interview has appeared on The Atlantic, Ancient DNA Is Rewriting Human (and Neanderthal) History, on the occasion of the publication of David Reich’s book Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past.

Some interesting excerpts (I have emphasized some of Reich’s words):

On the efficiency of the Reich Lab

Zhang: How much does it cost to process an ancient DNA sample right now?

Reich: In our hands, a successful sample costs less than $200. That’s only two or three times more than processing them

Pleistocene North African genomes link Near Eastern and sub-Saharan African human populations


Pleistocene North African genomes link Near Eastern and sub-Saharan African human populations, by van de Loosdrecht et al. Science (2018).


North Africa is a key region for understanding human history, but the genetic history of its people is largely unknown. We present genomic data from seven 15,000-year-old modern humans from Morocco, attributed to the Iberomaurusian culture. We find a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East. We do not find evidence for gene flow from Paleolithic Europeans into Late Pleistocene North Africans

Model for the spread of Transeurasian (Macro-Altaic) communities with farming


Austronesian influence and Transeurasian ancestry in Japanese: A case of farming/language dispersal, by Martine Robbeets, Max Planck Institute for the Science of Human History.


In this paper, I propose a hypothesis reconciling Austronesian influence and Transeurasian ancestry in the Japanese language, explaining the spread of the Japanic languages through farming dispersal. To this end, I identify the original speech community of the Transeurasian language family as the Neolithic Xinglongwa culture situated in the West Liao River Basin in the sixth millennium bc. I argue that the separation of the Japanic branch from the other Transeurasian languages and

Two sources of archaic Denisovan ancestry in East Asia, one possibly after the isolation of Native Americans


Open access paper Analysis of Human Sequence Data Reveals Two Pulses of Archaic Denisovan Admixture, by Sharon L. Browning, Brian L. Browning, Zhou, Tucci, & Akey, Cell (2018).


Anatomically modern humans interbred with Neanderthals and with a related archaic population known as Denisovans. Genomes of several Neanderthals and one Denisovan have been sequenced, and these reference genomes have been used to detect introgressed genetic material in present-day human genomes. Segments of introgression also can be detected without use of reference genomes, and doing so can be advantageous for finding introgressed segments that are less closely related to the

Uralic as a Corded Ware substrate of Indo-Iranian, and loanwords in Finno-Ugric

Asko Parpola has recently published a new paper, Finnish vatsa ~ Sanskrit vatsá and the formation of Indo-Iranian and Uralic languages.


Finnish vatsa ‘stomach’ < PFU *vaćća < Proto-Indo-Aryan *vatsá- ‘calf’ < PIE *vet-(e)s-ó- ‘yearling’ contrasts with Finnish vasa- ‘calf’ < Proto-Iranian *vasa- ‘calf’. Indo-Aryan -ts- versus Iranian -s- refl ects the divergent development of PIE *-tst- in the Iranian branch (> *-st-, with Greek and Balto-Slavic) and in the Indo-Aryan branch ( > *-tt-, probably due to Uralic substratum). The split of Indo-Iranian can be traced in the archaeological record to the differentiation of the Yamnaya culture

Genetic ancestry of Hadza and Sandawe peoples reveals ancient population structure in Africa

Open access paper Genetic Ancestry of Hadza and Sandawe Peoples Reveals Ancient Population Structure in Africa, by Shriner, Tekola-Ayele, Adeyemo, & Rotimi, GBE (2018).

Abstract (emphasis mine):

The Hadza and Sandawe populations in present-day Tanzania speak languages containing click sounds and therefore thought to be distantly related to southern African Khoisan languages. We analyzed genome-wide genotype data for individuals sampled from the Hadza and Sandawe populations in the context of a global data set of 3,528 individuals from 163 ethno-linguistic groups. We found that Hadza and Sandawe individuals share ancestry distinct from and most closely related to Omotic ancestry

First Iberian R1b-DF27 sample, probably from incoming East Bell Beakers


I had some more time to read the paper by Valdiosera et al. (2018) and its supplementary material.

One of the main issues since the publication of Olalde et al. (2018) (and its hundreds of Bell Beaker samples) was the lack of a clear Y-DNA R1b-DF27 subclades among East Bell Beaker migrants, which left us wondering when the subclade entered the Iberian Peninsula, since it could have (theoretically) happened from the Chalcolithic to the Iron Age.

My prediction was that this lineage found today widespread among the Iberian population crossed the Pyrenees quite early, during the Chalcolithic, with … Read the rest

Iberian prehistoric migrations in Genomics from Neolithic, Chalcolithic, and Bronze Age


New open access paper Four millennia of Iberian biomolecular prehistory illustrate the impact of prehistoric migrations at the far end of Eurasia, by Valdiosera, Günther, Vera-Rodríguez, et al. PNAS (2018) published ahead of print.

Abstract (emphasis mine)

Population genomic studies of ancient human remains have shown how modern-day European population structure has been shaped by a number of prehistoric migrations. The Neolithization of Europe has been associated with large-scale migrations from Anatolia, which was followed by migrations of herders from the Pontic steppe at the onset of the Bronze Age. Southwestern Europe was one of the last parts of
