Interesting paper Excavation at the Razdolnoe site on the Kalmius river in 2010, by N. Kotova, D. Anthony, D. Brown, S. Degermendzhy, P. Crabtree, In: Archaeology and Palaeoecology of the Ukrainian Steppe / IA NAS of Ukraine, Kyiv 2017.
Nothing new probably to those who have read Anthony (2007), but this new publication of his research on the North Pontic region seems to contradict recent papers which cast doubts on the presence of early forms of domestication in the North Pontic steppe, and would reject thus also the arrival of domestication to Khvalynsk from a southern route.… Read the rest “Domestication spread probably via the North Pontic steppe to Khvalynsk… but not horse riding”
New paper, behind paywall, Ancient genomes revisit the ancestry of domestic and Przewalski’s horses, by Gaunitz et al., Science (2018)
The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5,500 ya, but the exact nature of early horse domestication remains controversial. We generated 42 ancient horse genomes, including 20 from Botai. Compared to 46 published ancient and modern horse genomes, our data indicate that Przewalski’s horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4,000 ya to present only

I have written before about how the Late Neolithic sample from Zvejnieki seemed to be an outlier among Corded Ware samples (read also the Admixture analysis section on the IEDDM), due to its position in PCA, even more than its admixture components or statistical comparison might show.
In the recent update to Northern European samples in Mittnik et al. (2018), an evaluation of events similar to the previous preprint (2017) is given:
Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the
