Language evolution and language change related to ancient DNA

language-change-east-west

An interesting special issue of the journal Language Evolution has appeared, dedicated to Ancient DNA and language evolution.

Also, check out the preprint at BioRxiv, Geospatial distributions reflect rates of evolution of features of language, by Kauhanen et al. (2018).

Abstract:

Different structural features of human language change at different rates and thus exhibit different temporal stabilities. Existing methods of linguistic stability estimation depend upon the prior genealogical classification of the world’s languages into language families; these methods result in unreliable stability estimates for features which are sensitive to horizontal transfer between families and whenever data are aggregated

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

corded-ware-regions-main

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””

From Proto-Slavic into Germanic or from Germanic into Proto-Slavic? A review of controversial loanwords

antiquity_classical_Europe

Interesting new article From Proto-Slavic into Germanic or from Germanic into Proto-Slavic? A review of controversial loanwords, by Noińska Marta and Rychło Mikołaj in Studia Rossica Gedanensia (2017) 4:39-52.

Abstract:

Germanic loanwords in Proto-Slavic have been comprehensively analysed by both Western and Eastern scholars, however the problem of borrowings in the opposite direction received far less attention, especially among Western academics. It is worth noticing that Viktor Martynov (1963) proposed as many as 40 borrowings and penetrations from Proto-Slavic into Proto-Germanic. Among these, there are nine (*bljudo, 40 Marta Noińska, Mikołaj Rychło *kupiti, *lěkъ, *lugъ, *lukъ, *plugъ, *pъlkъ, *skotъ,

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

neolithic-steppe

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

baltic-region-mittnik

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
