Prehistoric loan relations: Foreign elements in the Proto-Indo-European vocabulary

An interesting ongoing web project, Prehistoric loan relations, on potential loans of Proto-Indo-European words, from Uralic-Yukaghir, Caucasian, and Middle Eastern influence.

Based on a Ph.D. thesis by Bjørn (2017) Foreign elements in the Proto-Indo-European vocabulary (PDF).

From the website (emphasis mine):

This page allows historical linguists to compare and scrutinize proposed prehistoric lexical borrowings from the perspective of Proto-Indo-European. The first entries are all (135 in total) extracted from my master’s thesis “Foreign elements in the Proto-Indo-European vocabulary” (Bjørn 2017). Comments are encouraged at the bottom of each entry. New entries will be added, also on request.

Storytelling was a source for cooperation in hunter-gatherer societies before religion

A new article, Cooperation and the evolution of hunter-gatherer storytelling, by Smith et al., Nature Communications (2017).

Storytelling is a human universal. From gathering around the camp-fire telling tales of ancestors to watching the latest television box-set, humans are inveterate producers and consumers of stories. Despite its ubiquity, little attention has been given to understanding the function and evolution of storytelling. Here we explore the impact of storytelling on hunter-gatherer cooperative behaviour and the individual-level fitness benefits to being a skilled storyteller. Stories told by the Agta, a Filipino hunter-gatherer population, convey messages relevant to coordinating behaviour in a

Migration, acculturation, and the maintenance of between-group cultural variation

Preprint at BioRxiv, Migration, acculturation, and the maintenance of between-group cultural variation, by Alex Mesoudi (2017)

Abstract:

How do migration and acculturation affect within- and between-group cultural variation? Classic models from population genetics show that migration rapidly breaks down between-group genetic structure. However, in the case of cultural evolution, migrants (or their children) can acculturate to local cultural behaviors via social learning processes such as conformity, potentially preventing migration from eliminating between-group cultural variation. To explore this verbal claim formally, here I present models that quantify the effect of migration and acculturation on between-group cultural variation, first for a

On the origin of language and human evolution

A rather risky preprint at BioRxiv, Language evolution to revolution: the jump from finite communication system with many words to infinite recursive language was associated with acquisition of mental synthesis, by Andrey Vyshedskiy (2017).

Abstract:

There is overwhelming archeological and genetic evidence that modern speech apparatus was acquired by hominins by 600,000 years ago. There is also widespread agreement that behavioral modernity arose around 100,000 years ago. We attempted to answer three crucial questions: (1) what triggered the acquisition of behavioral modernity 100,000 years ago, (2) why there was a long gap between acquisition of modern speech apparatus and

Expansion of peoples associated with spread of haplogroups: Mongols and C3*-F3918, Arabs and E-M183 (M81)

The expansion of peoples is known to be associated with the spread of a certain admixture component, joint with the expansion and reduction in variability of a haplogroup. In other words, few male lineages are usually more successful during the expansion.

Known examples include:

Neolithic farmers from the Middle East expanding with haplogroup G2a;
Natufian component (Levant hunter-gatherers or later, Neolithic farmers) and haplogroup E southward into Africa;
CHG component expansion with haplogroup J;
WHG expansion into east Europe in the Palaeolithic and Mesolithic with haplogroup R1b;
The expansion of “steppe component” with the Corded Ware culture and

Globular Amphora not linked to Pontic steppe migrants – more data against Kristiansen’s Kurgan model of Indo-European expansion

New open access article, Genome diversity in the Neolithic Globular Amphorae culture and the spread of Indo-European languages, by Tassi et al. (2017).

Abstract:

It is unclear whether Indo-European languages in Europe spread from the Pontic steppes in the late Neolithic, or from Anatolia in the Early Neolithic. Under the former hypothesis, people of the Globular Amphorae culture (GAC) would be descended from Eastern ancestors, likely representing the Yamnaya culture. However, nuclear (six individuals typed for 597 573 SNPs) and mitochondrial (11 complete sequences) DNA from the GAC appear closer to those of earlier Neolithic groups than to

The renewed ‘Kurgan model’ of Kristian Kristiansen and the Danish school: “The Indo-European Corded Ware Theory”

A popular science article on Indo-European migrations has appeared at Science News, entitled How Asian nomadic herders built new Bronze Age cultures, signed by Bruce Bower. While the article is well-balanced and introduces new readers to the current status quo of the controversy on Indo-European migrations – including the opposing theories led by Kristiansen/Anthony vs. Heyd – , it reverberates yet again the conclusions of the 2015 Nature articles on the subject, especially with its featured image.

I have argued many times why the recent ‘Yamnaya -Corded Ware -Bell Beaker’ migration model is wrong, mainly within my … Read the rest “The renewed ‘Kurgan model’ of Kristian Kristiansen and the Danish school: “The Indo-European Corded Ware Theory””

mtDNA haplogroup frequency analysis from Verteba Cave supports a strong cultural frontier between farmers and hunter-gatherers in the North Pontic steppe

New preprint paper at BioRxiv, led by a Japanese researcher, with analysis of mtDNA of Trypillians from Verteba Cave, Analysis of ancient human mitochondrial DNA from Verteba Cave, Ukraine: insights into the origins and expansions of the Late Neolithic-Chalcolithic Cututeni-Tripolye Culture, by Wakabayashi et al. (2017).

Abstract:

Background: The Eneolithic (~5,500 yrBP) site of Verteba Cave in Western Ukraine contains the largest collection of human skeletal remains associated with the archaeological Cucuteni-Tripolye Culture. Their subsistence economy is based largely on agro-pastoralism and had some of the largest and most dense settlement sites during the Middle Neolithic in

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

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
