The genetic and cultural barrier of the Pontic-Caspian steppe – forest-steppe ecotone

steppe-forest-steppe-biomes

We know that the Caucasus Mountains formed a persistent prehistoric barrier to cultural and population movements. Nevertheless, an even more persistent frontier to population movements in Europe, especially since the Neolithic, is the Pontic-Caspian steppe – forest-steppe ecotone.

Like the Caucasus, this barrier could certainly be crossed, and peoples and cultures could permeate in both directions, but there have been no massive migrations through it. The main connection between both regions (steppe vs. forest-steppe/forest zone) was probably through its eastern part, through the Samara region in the Middle Volga.

The chances of population expansions crossing this natural … Read the rest “The genetic and cultural barrier of the Pontic-Caspian steppe – forest-steppe ecotone”

Spread of Y. pestis, earlier than previously thought, may have caused Neolithic decline

spread-yersinia-pestis

Open access Emergence and Spread of Basal Lineages of Yersinia pestis during the Neolithic Decline, by Rascovan et al. Cell (2018)

Abstract (emphasis mine):

Between 5,000 and 6,000 years ago, many Neolithic societies declined throughout western Eurasia due to a combination of factors that are still largely debated. Here, we report the discovery and genome reconstruction of Yersinia pestis, the etiological agent of plague, in Neolithic farmers in Sweden, pre-dating and basal to all modern and ancient known strains of this pathogen. We investigated the history of this strain by combining phylogenetic and molecular clock analyses of the bacterial

A very “Yamnaya-like” East Bell Beaker from France, probably R1b-L151

Interesting report by Bernard Sécher on Anthrogenica, about the Ph.D. thesis of Samantha Brunel from Institut Jacques Monod, Paris, Paléogénomique des dynamiques des populations humaines sur le territoire Français entre 7000 et 2000 (2018).

NOTE. You can visit Bernard Sécher’s blog on genetic genealogy.

A summary from user Jool, who was there, translated into English by Sécher (slight changes to translation, and emphasis mine):

They have a good hundred samples from the North, Alsace and the Mediterranean coast, from the Mesolithic to the Iron Age.

There is no major surprise compared to the rest of Europe. On the PCA

The Yampil Barrow complex and the Yamna connection with forest-steppe cultures

Researchers involved in the investigation of the Yampil Barrow Complex are taking the opportunity of their latest genetic paper to publish and upload more papers in Academia.edu.

Corded Ware culture origins: The Final Frontier

corded-ware-yamna-bell-beaker

As you can imagine from my latest posts (on kurgan origins and on Sredni Stog), I am right now in the middle of a revision of the Corded Ware culture for my Indo-European demic diffusion model, to see if I can add something new to the draft. And, as you can see, even with ancient DNA on the table, the precise origin of the Corded Ware migrants – in spite of the imaginative efforts of the Copenhagen group to control the narrative – are still unknown.

Sredni Stog, Proto-Corded Ware, and their “steppe admixture”

steppe-eneolithic-migrations

Once the haplogroups of the announced West Yamna and Yamna settlers in Hungary and Khvalynsk from Ekaterinovka appear, it is to be expected that there won’t be much discussion on the Y-DNA bottlenecks that affected Khvalynsk – Yamna migrations.

So let’s cut to the chase and see where Corded Ware peoples (mainly of R1a-Z645 subclades) got their so-called “steppe admixture” different from that of Yamna. Because, as you might have realized by now, Sredni Stog – and consequently Corded Ware – remains nowadays an undefined (archaeological) mess.

Rassamakin explains it quite well, in the chapter Eneolithic of the Black Read the rest “Sredni Stog, Proto-Corded Ware, and their “steppe admixture””

Kurgan origins and expansion with Khvalynsk-Novodanilovka chieftains

burials-ochre-steppe

The concept of ‘Kurgan peoples’ is a general idea whereby ‘kurgan builders’ are identified with Indo-European speakers. It is a consequence of the oversimplification of Gimbutas’ theory, and is still widespread among linguists, archaeologists, geneticists, and amateurs alike.

NOTE. On the already simplistic assumptions of Gimbutas regarding the so-called ‘kurgan’ burials, see e.g. Häusler’s early criticism.

However, as more ancient DNA studies appear, many ancient cultures once held as ‘kurganized’ are becoming more and more clearly disconnected from Proto-Indo-Europeans: So for example Varna, Cucuteni-Trypillia, Maykop, or Northern Iranian kurgan builders.

The first marked burials

Cereal cultivation and processing in Trypillian mega-sites

New paper (behind paywall) Where are the cereals? Contribution of phytolith analysis to the study of subsistence economy at the Trypillia site Maidanetske (ca. 3900-3650 BCE), central Ukraine, by Dal Corso et al. Journal of Arid Environments (2018).

Interesting excerpts (only introduction and conclusions, emphasis mine):

Archaeological setting at the site of Maidanetske, Ukraine

From ca. 4800 to 3350 BCE, Trypillia settlements were widespread over parts of eastern Romania, Moldova and Ukraine (Menotti and Korvin-Piotrovskiy, 2012; Müller et al., 2016; Videiko, 2004). Maidanetske (Fig. 1B) is one of the so-called “mega-sites” which developed during ca. 3900–3400 BCE in central

R1b-V88 migration through Southern Italy into Green Sahara corridor, and the Afroasiatic connection

Open access article The peopling of the last Green Sahara revealed by high-coverage resequencing of trans-Saharan patrilineages, by D’Atanasio, Trombetta, Bonito, et al., Genome Biology (2018) 19:20.

Abstract:

Background
Little is known about the peopling of the Sahara during the Holocene climatic optimum, when the desert was replaced by a fertile environment.

Results
In order to investigate the role of the last Green Sahara in the peopling of Africa, we deep-sequence the whole non-repetitive portion of the Y chromosome in 104 males selected as representative of haplogroups which are currently found to the north and to the south of
