Decline of genetic diversity in ancient domestic stallions in Europe

Open access research article Decline of genetic diversity in ancient domestic stallions in Europe, by Wutke et al., Science (2018), 4(4):eaap9691.

Abstract (emphasis mine):

Present-day domestic horses are immensely diverse in their maternally inherited mitochondrial DNA, yet they show very little variation on their paternally inherited Y chromosome. Although it has recently been shown that Y chromosomal diversity in domestic horses was higher at least until the Iron Age, when and why this diversity disappeared remain controversial questions. We genotyped 16 recently discovered Y chromosomal single-nucleotide polymorphisms in 96 ancient Eurasian stallions spanning the early domestication stages (Copper and

Integrative studies of cultural evolution: crossing disciplinary boundaries to produce new insights

Interesting open access article Integrative studies of cultural evolution: crossing disciplinary boundaries to produce new insights, Oren Kolodny, Marcus W. Feldman, Nicole Creanza, Philos. Trans. Royal Soc. B (2018).

Abstract:

Culture evolves according to dynamics on multiple temporal scales, from individuals’ minute-by-minute behaviour to millennia of cultural accumulation that give rise to population-level differences. These dynamics act on a range of entities—including behavioural sequences, ideas and artefacts as well as individuals, populations and whole species—and involve mechanisms at multiple levels, from neurons in brains to inter-population interactions. Studying such complex phenomena requires an integration of perspectives from a diverse

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

Evolutionary forces in language change depend on selective pressure, but also on random chance

english-language-evolution

A new interesting paper from Nature: Detecting evolutionary forces in language change, by Newberry, Ahern, Clark, and Plotkin (2017). Discovered via Science Daily.

The following are excerpts of materials related to the publication (written by Katherine Unger Baillie), from The University of Pennsylvania:

Examining substantial collections of annotated texts dating from the 12th to the 21st centuries, the researchers found that certain linguistic changes were guided by pressures analogous to natural selection — social, cognitive and other factors — while others seem to have occurred purely by happenstance.

“Linguists usually assume that when a change occurs in

From Adamic or the language of the Garden of Eden until the Tower of Babel: the confusion of tongues and the earliest dialects attested

No, I didn’t have a revelation today. I am just offering a little support exactly to what Dawkins and his Brights dislike, to show them extreme action causes extreme (re)actions. I’d like to play their radical game, too, offering some help in linguistics to those who have only naïve theories on the language of Eden.

These are the statements about the Adamic language and the Tower of Babel as Abrahamic texts, beliefs and traditions show:

  • Adamic was the language spoken by Adam and Eve in the Garden of Eden. Adamic is typically identified with either the

Rhetoric of debates, discussions and arguments: Useful destructive criticism for scientific & academic research, reasons and personal opinions; the example of Proto-Indo-European language revival

Rhetoric (Wikipedia) is the art of harnessing reason, emotions and authority, through language, with a view to persuade an audience and, by persuading, to convince this audience to act, to pass judgement or to identify with given values. The word derives from PIE root wer-, ‘speak’, as in MIE zero-grade wrdhom, ‘word’, or full-grade werdhom, ‘verb’; from wrētōr ρήτωρ (rhētōr), “orator” [built like e.g. wistōr (<*widtor), Gk. ἵστωρ (histōr), “a wise man, one who knows right, a judge” (from which ‘history’), from PIE root weid-, ‘see, know’]; from … Read the rest “Rhetoric of debates, discussions and arguments: Useful destructive criticism for scientific & academic research, reasons and personal opinions; the example of Proto-Indo-European language revival”
