mtDNA suggest original East Germanic population linked to Jutland Iron Age and Bell Beaker

Open Access article A mosaic genetic structure of the human population living in the South Baltic region during the Iron Age, by Stolarek et al., at Scientific Reports 8:2455 (2018).

About the site:

Kowalewko is a village in Wielkopolskie vojevodship, close to Poznan, in the middle reaches of the Samica Kierska river. Biritual Roman Age cemetery (site 12), dated from the mid-1st to the beginning of 3rd century AD, is located in the featureless arable fields at the South and West of the village

About the Wielbark culture:

Chronology spans almost all the Roman Iron Age, since ca. 20

Genomic history of South-East Asia: eastern Polynesians, Peninsular Malaysia and North Borneo

Two recent interesting genetic papers:

1. Open Access Investigating the origins of eastern Polynesians using genome-wide data from the Leeward Society Isles, by Hudjashov et al., at Scientific Reports (2018)

Abstract:

The debate concerning the origin of the Polynesian speaking peoples has been recently reinvigorated by genetic evidence for secondary migrations to western Polynesia from the New Guinea region during the 2nd millennium BP. Using genome-wide autosomal data from the Leeward Society Islands, the ancient cultural hub of eastern Polynesia, we find that the inhabitants’ genomes also demonstrate evidence of this episode of admixture, dating to 1,700–1,200 BP.

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

“How Asian nomadic herders built new Bronze Age cultures”

I recently wrote about a good informal summary of genomic research in 2017 for geneticists.

I found a more professional review article, How Asian nomadic herders built new Bronze Age cultures, by Bruce Bower, appeared in Science News (25th Nov. 2017).

NOTE: I know, I know, the Pontic-Caspian steppe is in East Europe, not Asia, but what can you do about people’s misconceptions regarding European geography? After all, the division is a conventional one, there are not many landmarks to divide Eurasia…

It refers to Kristiansen’s model, which we already know supports the expansion of IE … Read the rest ““How Asian nomadic herders built new Bronze Age cultures””

The myth of mixed language, the concepts of culture core and package, and the invention of ‘Steppe folk’

I recently read some papers which, albeit apparently unrelated, should be of interest for many today.

Mixed language

The myth of the mixed languages, by Kees Versteeg, in Advances in Maltese linguistics, ed. by Benjamin Saade and Mauro Tosco, 217-238. Berlin and New York: Mouton de Gruyter, 2017 [uncorrected proofs]

This paper focuses on the usefulness of the label ‘mixed languages’ as an analytical tool. Section 1 sketches the emergence of the biological paradigm in linguistics and its effect on the contemporary debate about mixed languages. Sections 2 and 3 discuss two processes that have been held responsible

Genetic prehistory of the Baltic Sea region and Y-DNA: Corded Ware and R1a-Z645, Bronze Age and N1c

Open Access The genetic prehistory of the Baltic Sea region, by Mittnik et al., Nature Communications 9: 442 (2018), based on preprint The Genetic History of Northern Europe, at BioRxirv.

As you can see, it follows my predictions in terms of haplogroups, and sadly the same trend to substitute ‘Yamna’ for ‘steppe’ while keeping linguistic interpretations unchanged…

Important excerpts for the Indo-European question (emphasis mine):

Mesolithic to Neolithic

In the archaeological understanding, the transition from Mesolithic to Neolithic in the Eastern Baltic region does not coincide with a large-scale population turnover and a stark shift in economy

Reconstructing the demographic history of the Himalayan and adjoining populations

Reconstructing the demographic history of the Himalayan and adjoining populations, by Tamang, R., Chaubey, G., Nandan, A. et al. Hum Genet (2018).

Abstract (emphasis mine):

The rugged topography of the Himalayan region has hindered large-scale human migrations, population admixture and assimilation. Such complexity in geographical structure might have facilitated the existence of several small isolated communities in this region. We have genotyped about 850,000 autosomal markers among 35 individuals belonging to the four major populations inhabiting the Himalaya and adjoining regions. In addition, we have genotyped 794 individuals belonging to 16 ethnic groups from the same region, for uniparental

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”

Earliest modern humans outside Africa and ancient genomic history

Interesting new paper at Science, The earliest modern humans outside Africa, by Hershkovitz et al., Science (2018) Vol. 359, Issue 6374, pp. 456-459

Introduction:

Recent paleoanthropological studies have suggested that modern humans migrated from Africa as early as the beginning of the Late Pleistocene, 120,000 years ago. Hershkovitz et al. now suggest that early modern humans were already present outside of Africa more than 55,000 years earlier (see the Perspective by Stringer and Galway-Witham). During excavations of sediments at Mount Carmel, Israel, they found a fossil of a mouth part, a left hemimaxilla, with almost complete dentition.

The sediments
