Actually watched it for the first time straight through. Anthony, Willerslev and Krause all make an appearance.
Someone forgot to tell Anthony there were very few horses in Corded Ware and the carts were pulled by cattle.
Willerslev straight out says the plague started among the steppe people and they spread it to LN Europe, whose inhabitants had less immunity to it. Shades of the poor people of the Americas.
I don't remember it being as dogmatic as that in the papers. Among the "native" survivors he thinks the men were killed and the women absorbed. Well, we know where "he" stands.
Oh, he also says he used to have a "romantic" dream of being a horse riding Indo-European. Good grief, not another Eurogenes like "romantic" about blonde cowboys of the steppes. What a jerk. And this from a middle aged academic.
To his credit, perhaps, he says that given the disease and violence he'd rather live in the present. Or maybe the idea of killing other people was "romantic", but dying oneself of plague was a step too far.
