New preprint The Arrival of Steppe and Iranian Related Ancestry in the Islands of the Western Mediterranean by Fernandes, Mittnik, Olalde et al. bioRxiv (2019)
Interesting excerpts (emphasis in bold; modified for clarity):
Balearic Islands: The expansion of Iberian speakers
Mallorca_EBA dates to the earliest period of permanent occupation of the islands at around 2400 BCE. We parsimoniously modeled Mallorca_EBA as deriving 36.9 ± 4.2% of her ancestry from a source related to Yamnaya_Samara; (…). We next used qpAdm to identify “proximal” sources for Mallorca_EBA’s ancestry that are more closely related to this individual in space and time, and found

Scythian samples from the North Pontic area are far more complex than what could be seen at first glance. From the new Y-SNP calls we have now thanks to the publications at Molgen (see the spreadsheet) and in Anthrogenica threads, I think this is the basis to work with:
NOTE. I understand that writing a paper requires a lot of work, and probably statistical methods are the main interest of authors, editors, and reviewers. But it is difficult to comprehend how any user of open source tools can instantly offer a more complex assessment of the samples’ Y-SNP … Read the rest “R1a-Z280 lineages in Srubna; and first Palaeo-Balkan R1b-Z2103?”

New paper (behind paywall), Genomic history of the Sardinian population, by Chiang et al. Nature Genetics (2018), previously published as a preprint at bioRxiv (2016).
#EDIT (18 Sep 2018): Link to read paper for free shared by the main author.
Interesting excerpts (emphasis mine):
Our analysis of divergence times suggests the population lineage ancestral to modern-day Sardinia was effectively isolated from the mainland European populations ~140–250 generations ago, corresponding to ~4,300–7,000 years ago assuming a generation time of 30 years and a mutation rate of 1.25 × 10−8 per basepair per generation. (…) in terms of relative values,

Open access Ancient DNA from Chalcolithic Israel reveals the role of population mixture in cultural transformation, by Harney et al. Nature Communications (2018).
Interesting excerpts (emphasis mine, reference numbers deleted for clarity):
The material culture of the Late Chalcolithic period in the southern Levant contrasts qualitatively with that of earlier and later periods in the same region. The Late Chalcolithic in the Levant is characterized by increases in the density of settlements, introduction of sanctuaries, utilization of ossuaries in secondary burials, and expansion of public ritual practices as well as an efflorescence of symbolic motifs sculpted and

New paper (behind paywall), A tale of two rice varieties: Modelling the prehistoric dispersals of japonica and proto-indica rices, by Silva et al., The Holocene (2018).
Interesting excerpts (emphasis mine):
Our empirical evidence comes from the Rice Archaeological Database (RAD). The first version of this database was used for a synthesis of rice dispersal by Fuller et al. (2010), a slightly expanded dataset (version 1.1) was used to model the dispersal of rice, land area under wet rice cultivation and associated methane emissions from 5000–1000 BP (Fuller et al., 2011). The present dataset (version 2) was used in

Open access structured abstract for The first horse herders and the impact of early Bronze Age steppe expansions into Asia from Damgaard et al. Science (2018) 360(6396):eaar7711.
Abstract (emphasis mine):
The Eurasian steppes reach from the Ukraine in Europe to Mongolia and China. Over the past 5000 years, these flat grasslands were thought to be the route for the ebb and flow of migrant humans, their horses, and their languages. de Barros Damgaard et al. probed whole-genome sequences from the remains of 74 individuals found across this region. Although there is evidence for migration into Europe from the steppes, the

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

Interesting press release from the Institute of Archaeology at Adam Mickiewicz University in Poznań:
In an open access report last year, Anthropological Description of Skeletal Material from the Dniester Barrow-cemetery Complex, Yampil Region, Vinnitsa Oblast (Ukraine), the team lead by Liudmyla Litvinova – of the Ukrainian Academy of Science – published their findings from the skeletons in different burial mounds along the border with Moldavia, ranging from Eneolithic to Iron Age burials.
In one Yamnaya burial rested a young woman aged 25-30. It was so described in the original paper:
Barrow 3A, feature 10. A very poorly-preserved skeleton
