In recent years, it has become increasingly clear that a combination of genetics, archaeology, and historical-comparative linguistics is the only sensible way to reach a deeper and more subtle understanding of the Indo-European question. By now, there is practically general agreement that at the very least, “Indo-Tocharian,”1 defined as the predecessor of all branches of the Indo-European family with the exception of Anatolian, originated in the Pontic–Caspian steppe. The speakers of this common language have been archaeologically connected with the Yamnaya horizon, later continued in northern Europe as the Corded Ware culture.2
