Davidski at Eurogenes is more than a little appalled, and rightly so, that the seemingly reputable Max-Planck-Institut für Menschheitsgeschichte linguistics research center in Germany, is still circulating in a flashy animated presentation, the claim that the Indo-European languages made their way to South Asia, Western Europe and Eastern Europe as separate spokes from a common Armenian hub, around 8000 years ago.
This claim, as Davidski correctly points out with solid, published research support, is contrary to overwhelming evidence from modern and ancient DNA and historical accounts to place that this DNA evidence in a linguistic context.
At this point, it should be really hard for any legitimate peer reviewed publication to take a paper proposing that hypothesis since it really doesn't hold water. There are certainly some respects in which the orthodox paradigm in the field of Indo-European linguistic origins could be wrong. I even support some of those hypotheses myself. But, this is not one of them.
Honestly, it is a little hard to figure out why an institution like that could support a position that rings of a Trump-like belief in "alternative facts". But, inertia is a powerful thing and old scholars can be very slow to acknowledge that their old hypotheses have been obviously disproven.
