Yamnaya replaced Europeans, but admixed heavily as they spread to Asia

Recent papers The formation of human populations in South and Central Asia, by Narasimhan, Patterson et al. Science (2019) and An Ancient Harappan Genome Lacks Ancestry from Steppe Pastoralists or Iranian Farmers, by Shinde et al. Cell (2019).

I am currently not on holidays anymore, and the information in the paper is huge, with many complex issues raised by the new samples and analyses rather than solved, so I will stick to the Indo-European question, … Read the rest “Yamnaya replaced Europeans, but admixed heavily as they spread to Asia”

Eurasian steppe chariots and social complexity during the Bronze Age

New paper (behind paywall), Eurasian Steppe Chariots and Social Complexity During the Bronze Age, by Chechushkov and Epimakhov, Journal of World Prehistory (2018).

Interesting excerpts (emphasis mine):

Nowadays, archaeologists distinguish at least three Bronze Age pictorial traditions on the basis of style, and demonstrate some parallels in the material culture. The earliest is the Yamna–Afanasievo tradition, which is characterized by the symbolic depiction of sun-headed men and animals. Another tradition is a record of the Andronovo people (Kuzmina 1994; Novozhenov 2012), who depicted in it their everyday life and the importance of wheeled transport (Novozhenov 2014a, b). Although petroglyphs

The origin of social complexity in the development of the Sintashta culture

Very interesting PhD thesis by Igor Chechushkov, Bronze Age human communities in the Southern Urals steppe: Sintashta-Petrovka social and subsistence organization (2018).

Abstract:

Why and how exactly social complexity develops through time from small-scale groups to the level of large and complex institutions is an essential social science question. Through studying the Late Bronze Age Sintashta-Petrovka chiefdoms of the southern Urals (cal. 2050–1750 BC), this research aims to contribute to an understanding of variation in the organization of local communities in chiefdoms. It set out to document a segment of the Sintashta-Petrovka population not previously recognized in the archaeological record

BMAC: long term interaction between agricultural communities and steppe pastoralists in Central Asia

Interesting new paper Mixing metaphors: sedentary-mobile interactions and local-global connections in prehistoric Turkmenistan, by Rouse & Cerasetti, Antiquity (2018) 92:674-689.

Relevant excerpts (emphasis mine):

The Murghab alluvial fan in southern Turkmenistan witnessed some of the earliest encounters between sedentary farmers and mobile pastoralists from different cultural spheres. During the late third and early second millennia BC, the Murghab was home to the Oxus civilisation and formed a central node in regional exchange networks (Possehl 2005; Kohl 2007). The Oxus civilisation (or the Bactria-Margiana Archaeological Complex) relied on intensive agriculture to support a hierarchical society and specialised craft production of

Pasture usage by ancient pastoralists in Middle and Late Bronze Age Kazakhstan

Open access Pasture usage by ancient pastoralists in the northern Kazakh steppe informed by carbon and nitrogen isoscapes of contemporary floral biomes, by Miller et al. Archaeol Anthropol Sci (2018).

Interesting excerpts (emphasis mine):

Bronze age settlement, society, and subsistence in the northern Kazakh steppe

The Middle to Late Bronze Age (2200 to 1400 cal BCE) in the northern Kazakh steppe encompassed a major shift in settlement patterns from semi-sedentary pastoralism to more dispersed, mobile lifeways engaged in pastoral nomadism (Tkacheva 1999; Grigory’ev 2002; Koryakova and Epimakhov 2007; Kuz’mina 2007; Tkacheva and Tkachev 2008). Middle Bronze Age (2200 to

Y-DNA haplogroup R1b-Z2103 in Proto-Indo-Iranians?

We already know that the Sintashta -Andronovo migrants will probably be dominated by Y-DNA R1a-Z93 lineages. However, I doubt it will be the only Y-DNA haplogroup found.

I said in my predictions for this year that there could not be much new genetic data to ascertain how Pre-Indo-Iranian survived the invasion, gradual replacement and founder effects that happened in terms of male haplogroups after the arrival of late Corded Ware migrants, and that we should probably have to rely on anthropological explanations for language continuity despite genetic replacement, as in the Basque case.

Nevertheless, since … Read the rest “Y-DNA haplogroup R1b-Z2103 in Proto-Indo-Iranians?”
