Iberia in the Copper and Early Bronze Age: Cultural, demographic, and environmental analysis

bell-beaker-ritual

New paper (behind paywall), Cultural, Demographic and Environmental Dynamics of the Copper and Early Bronze Age in Iberia (3300–1500 BC): Towards an Interregional Multiproxy Comparison at the Time of the 4.2 ky BP Event, Blanco-González, Lillios, López-Sáez, et al. J World Prehist (2018).

Abstract (emphasis mine):

This paper presents the first comprehensive pan-Iberian overview of one of the major episodes of cultural change in later prehistoric Iberia, the Copper to Bronze Age transition (c. 2400–1900 BC), and assesses its relationship to the 4.2 ky BP climatic event. It synthesizes available cultural, demographic and palaeoenvironmental evidence by region between

Iberian prehistoric migrations in Genomics from Neolithic, Chalcolithic, and Bronze Age

iberia-neolithic-bronze-age

New open access paper Four millennia of Iberian biomolecular prehistory illustrate the impact of prehistoric migrations at the far end of Eurasia, by Valdiosera, Günther, Vera-Rodríguez, et al. PNAS (2018) published ahead of print.

Abstract (emphasis mine)

Population genomic studies of ancient human remains have shown how modern-day European population structure has been shaped by a number of prehistoric migrations. The Neolithization of Europe has been associated with large-scale migrations from Anatolia, which was followed by migrations of herders from the Pontic steppe at the onset of the Bronze Age. Southwestern Europe was one of the last parts of

Population replacement in Early Neolithic Britain, and new Bell Beaker SNPs

copper-age-late-bell-beaker

New (copyrighted) preprint at BioRxiv, Population Replacement in Early Neolithic Britain, by Brace et al. (2018).

Abstract (emphasis mine):

The roles of migration, admixture and acculturation in the European transition to farming have been debated for over 100 years. Genome-wide ancient DNA studies indicate predominantly Anatolian ancestry for continental Neolithic farmers, but also variable admixture with local Mesolithic hunter-gatherers. Neolithic cultures first appear in Britain c. 6000 years ago (kBP), a millennium after they appear in adjacent areas of northwestern continental Europe. However, the pattern and process of the British Neolithic transition remains unclear. We assembled genome-wide

Demographic research of Neolithic, Chalcolithic, and Bronze Age Europe

europe-demographic

I mentioned in the Indo-European demic diffusion model the need to assess absolute and relative population growth – as well as other demographic changes – to interpret genomic data from the different European regions studied.

One article I referred to was Demographic traces of technological innovation, social change and mobility: from 1 to 8 million Europeans (6000–2000 BCE), by Johannes Müller.

Excerpts (emphasis mine):

  • The neolithization of Northern and Northwestern Europe (probably with new forms of slash-and-burn agriculture; Feeser et al. 2012; Schier 2009) was also one of the causes for the population increase observed.

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

Something is very wrong with models based on the so-called ‘Yamnaya admixture’ – and archaeologists are catching up (II)

A new article by Leo S. Klejn tries to improve the Northern Mesolithic Proto-Indo-European homeland model of the Russian school of thought: The Steppe hypothesis of Indo-European origins remains to be proven, Acta Archaeologica, 88:1, 193–204.

Abstract:

Recent genetic studies have claimed to reveal a massive migration of the bearers of the Yamnaya culture (Pit-grave culture) to the Central and Northern Europe. This migration has supposedly lead to the formation of the Corded Ware cultures and thereby to the dispersal of Indo-European languages in Europe. The article is a summary presentation of available archaeological, linguistic, genetic and cultural data

Eneolithic Ukraine cultures of the North Pontic steppe and southern steppe-forest, on the Left Bank of the Dnieper

eneolithic-forest-zone

As I said before, Yuri Rassamakin is one archaeologist to follow closely for those interested in Neolithic and Chalcolithic Ukraine (ca. 5000-3300 BC), including Sredni Stog, and their potential connection with the Corded Ware culture, as well as the later expansion of Yamna into the region (and Yamna settlers into south-eastern Europe).

His recent studies include important sites (for Archaeology and recently also for Genomics) such us Dereivka and Alexandria, part of the North Pontic steppe and southern steppe-forest zone, on the Left Bank of the Dnieper river. According to him, many of these … Read the rest “Eneolithic Ukraine cultures of the North Pontic steppe and southern steppe-forest, on the Left Bank of the Dnieper”

The concept of “Outlier” in Human Ancestry (II): Early Khvalynsk, Sredni Stog, West Yamna, Iron Age Bulgaria, Potapovka, Andronovo…

yamna-corded-ware-bell-beaker

I already wrote about the concept of outlier in Human Ancestry, so I am not going to repeat myself. This is just an update of “outliers” in recent studies, and their potential origins (here I will repeat some of the examples):

Early Khvalynsk: the three samples from the Samara region have quite different positions in PCA, from nearest to EHG (of Y-DNA haplogroup R1a) to nearest to ANE ancestry (of Y-DNA haplogroup Q). This could represent the initial consequences of the second wave of ANE ancestry – as found later in Yamna samples from a neighbouring region -, … Read the rest “The concept of “Outlier” in Human Ancestry (II): Early Khvalynsk, Sredni Stog, West Yamna, Iron Age Bulgaria, Potapovka, Andronovo…”

Review article about Ancient Genomics, by Pontus Skoglund and Iain Mathieson
