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)

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

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).

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,

Another short communication by Juliette Blevins has just been posted, A single sibilant in Proto-Basque: *s, *Rs, *sT and the phonetic basis of the sibilant split:
Blevins (to appear) presents a new reconstruction of Proto-Basque, the mother of Basque and Aquitanian, based on standard methods in historical linguistics: the comparative method and the method of internal reconstruction. Where all previous reconstructions of Proto-Basque assume a contrast between two sibilants, *s, a voiceless apical sibilant, and *z a voiceless laminal sibilant (Martinet 1955; Michelena 1977; Lakarra 1995; Trask 1997), this proposal is unique in positing only a single sibilant *s.
