Nick Patterson, Iosif Lazaridis, and I developed new statistical methods that allowed us to estimate that in Germany, people buried with Corded Ware pots derive about three-quarters of their ancestry from groups related to the Yamnaya and the rest from people related to the farmers who had been the previous inhabitants of that region. Steppe ancestry has endured, as we also found it in all subsequent archaeological cultures of northern Europe as well as in all present-day northern Europeans.
