Early Iranian steppe nomadic pastoralists also show Y-DNA bottlenecks and R1b-L23

New paper (behind paywall) Ancient genomes suggest the eastern Pontic-Caspian steppe as the source of western Iron Age nomads, by Krzewińska et al. Science (2018) 4(10):eaat4457.

Interesting excerpts (emphasis mine, some links to images and tables deleted for clarity):

Late Bronze Age (LBA) Srubnaya-Alakulskaya individuals carried mtDNA haplogroups associated with Europeans or West Eurasians (17) including H, J1, K1, T2, U2, U4, and U5 (table S3). In contrast, the Iron Age nomads (Cimmerians, Scythians, and Sarmatians) additionally carried mtDNA haplogroups associated with Central Asia and the Far East (A, C, D, and M). The absence of East Asian mitochondrial

Origins of equine dentistry in Mongolia in the early first millennium BC

New paper (behind paywall) Origins of equine dentistry, by Taylor et al. PNAS (2018).

Interesting excerpts (emphasis mine):

The practice of horse dentistry by contemporary nomadic peoples in Mongolia, coupled with the centrality of horse transport to Mongolian life, both now and in antiquity, raises the possibility that dental care played an important role in the development of nomadic life and domestic horse use in the past. To investigate, we conducted a detailed archaeozoological study of horse remains from tombs and ritual horse inhumations across the Mongolian Steppe, assessing evidence for anthropogenic dental modifications and comparing our findings

Open access The End of the Kura-Araxes Culture as Seen from Nadir Tepesi in Iranian Azerbaijan, by Alizadeh, Maziar & Mohammadi, American Journal of Archaeology (2018) 122(3):463-477.

Interesting excerpts (emphasis mine):

The test trenches at Nadir Tepesi suggest that the Kura-Araxes occupation ended abruptly in the mid third millennium B.C.E. and that the site was then occupied or visited by a new group of people with new cultural traditions. Evidence for a significant destruction followed by the sharp discontinuity in the material culture could represent a violent termination of the Kura-Araxes occupation at Nadir Tepesi. This possibility provides one
