R1b-L23-rich Bell Beaker-derived Italic peoples from the West vs. Etruscans from the East

New paper (behind paywall) Ancient Rome: A genetic crossroads of Europe and the Mediterranean, by Antonio et al. Science (2019).

The paper offers a lot of interesting data concerning the Roman Empire and more recent periods, but I will focus on Italic and Etruscan origins.

NOTE. I have updated prehistoric maps with Y-DNA and mtDNA data, and also the PCA of ancient Eurasian samples by period including the recently published samples, now with added sample names to find them easily by searching the PDFs.

Ancient DNA reveals temporal population structure of pre-Incan and Incan periods in South‐Central Andes area

Ancient DNA reveals temporal population structure within the South‐Central Andes area, by Russo et al. Am. J. Phys. Anthropol. (2018).

Abstract (emphasis mine):

Objectives
The main aim of this work was to contribute to the knowledge of pre‐Hispanic genetic variation and population structure among the South‐central Andes Area by studying individuals from Quebrada de Humahuaca, North‐western (NW) Argentina.

Materials and methods
We analyzed 15 autosomal STRs in 19 individuals from several archaeological sites in Quebrada de Humahuaca, belonging to the Regional Developments Period (900–1430 AD). Compiling autosomal, mitochondrial, and Y‐chromosome data, we evaluated population structure and differentiation among eight

Y chromosome C2*-star cluster traces back to ordinary Mongols, rather than Genghis Khan

Article behind paywall, Whole-sequence analysis indicates that the Y chromosome C2*-Star Cluster traces back to ordinary Mongols, rather than Genghis Khan, by Wei, Yan, Lu, et al. Eur J Hum Genet (2018); 26:230–237

Abstract:

The Y-chromosome haplogroup C3*-Star Cluster (revised to C2*-ST in this study) was proposed to be the Y-profile of Genghis Khan. Here, we re-examined the origin of C2*-ST and its associations with Genghis Khan and Mongol populations. We analyzed 34 Y-chromosome sequences of haplogroup C2*-ST and its most closely related lineage. We redefined this paternal lineage as C2b1a3a1-F3796 and generated a highly revised phylogenetic tree of
