Almost Every Man in Europe Was Replaced. The DNA Says Who Did It.

Five thousand years ago, on the grass north of the Black Sea, a wagon is moving. Ask a man alive today in London, Dublin or Madrid where his father's father's line comes from, all the way back, and for most of them the answer is that wagon. This is the story of the Yamnaya, the herders of the steppe, told the way the ancient DNA has told it since 2015: who they were, what their bones say, the plague that was already in Europe, the Corded Ware and Beaker migrations, the grave at Koszyce, the Amesbury Archer, the strange collapse of male lines worldwide, why it was not a cavalry invasion, what milk has to do with famine, and the language most of us still speak. The Journey, Episode 3. Last time: farming and the first cities. Next time: the cities go to war.
