New paper (behind paywall) Genetic variation in populations from central Argentina based on mitochondrial and Y chromosome DNA evidence, by García, Pauro, Bailliet, Bravi & Demarchi, J. Hum. Genet (2018) 63: 493–507.
Abstract (emphasis mine):
We present new data and analysis on the genetic variation of contemporary inhabitants of central Argentina, including a total of 812 unrelated individuals from 20 populations. Our goal was to bring new elements for understanding micro-evolutionary and historical processes that generated the genetic diversity of the region, using molecular markers of uniparental inheritance (mitochondrial DNA and Y chromosome). Almost 76% of the individuals show

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?”
New paper (behind paywall) Agricultural origins on the Anatolian plateau, by Baird et al. PNAS (2018), published ahead of print (March 19).
Abstract (emphasis mine):
This paper explores the explanations for, and consequences of, the early appearance of food production outside the Fertile Crescent of Southwest Asia, where it originated in the 10th/9th millennia cal BC. We present evidence that cultivation appeared in Central Anatolia through adoption by indigenous foragers in the mid ninth millennium cal BC, but also demonstrate that uptake was not uniform, and that some communities chose to actively disregard cultivation. Adoption of cultivation

Open access paper Genetic Ancestry of Hadza and Sandawe Peoples Reveals Ancient Population Structure in Africa, by Shriner, Tekola-Ayele, Adeyemo, & Rotimi, GBE (2018).
Abstract (emphasis mine):
The Hadza and Sandawe populations in present-day Tanzania speak languages containing click sounds and therefore thought to be distantly related to southern African Khoisan languages. We analyzed genome-wide genotype data for individuals sampled from the Hadza and Sandawe populations in the context of a global data set of 3,528 individuals from 163 ethno-linguistic groups. We found that Hadza and Sandawe individuals share ancestry distinct from and most closely related to Omotic ancestry

New open access paper Population genomic analysis of elongated skulls reveals extensive female-biased immigration in Early Medieval Bavaria, by Veeramah, Rott, Groß, et al. PNAS (2018), published ahead of print.
First, a bit of context on the Bavarii:
Europe experienced a profound cultural transformation between Late Antiquity and the Middle Ages that laid the foundations of the modern political, social, and religious landscape. During this period, colloquially known as the “Migration Period,” the Roman Empire gradually dissolved, with 5th and 6th century historiographers and contemporary witnesses describing the formation and migration of numerous Germanic peoples, such as the Goths,

Open Access article Population Turnover in Remote Oceania Shortly after Initial Settlement, by Lipson, Skoglund, Spriggs, et al. (2018), based on the recent preprint at bioRxiv.
Ancient DNA from Vanuatu and Tonga dating to about 2,900–2,600 years ago (before present, BP) has revealed that the “First Remote Oceanians” associated with the Lapita archaeological culture were directly descended from the population that, beginning around 5000 BP, spread Austronesian languages from Taiwan to the Philippines, western Melanesia, and eventually Remote Oceania. Thus, ancestors of the First Remote Oceanians must have passed by the Papuan-ancestry populations they encountered in New

Pontus Skoglund writes (and shares publicly) his perspective on early postglacial migrations of hunter-gatherers into Scandinavia, in Northwest Passage to Scandinavia (Nat. Ecol. Evol.): an initial migration from the south and a second coastal migration north of the Scandinavian ice sheet.
He sums up the recently published Open Access paper Population genomics of Mesolithic Scandinavia: Investigating early postglacial migration routes and high-latitude adaptation, by Günther, Malmström , Svensson, Omrak, et al. PLoS Biol (2018) 16(1): e2003703, based on preprint at BioRxiv Genomics of Mesolithic Scandinavia reveal colonization routes and high-latitude adaptation (2017).
Scandinavia was one of

Abstract (in German):
Die älteste bisher bekannte Gefäßkeramik der Welt wurde in Südostchina von spätglazialen Jäger-Sammlern wahrscheinlich schon um 18.000 cal BC hergestellt. In den folgenden Jahrtausenden verbreitete sich die neue Technik bei Wildbeutergemeinschaften in der russischen Amur-Region, in Japan, Korea und Transbaikalien bekannt, bevor sie im frühen und mittleren
