Corded Ware culture
The proposed Indo-European migration has variously been dated to the end of the Neolithic (Marija Gimbutas: Corded Ware culture, Yamna culture, Kurgan culture), the early Neolithic (Colin Renfrew: Starčevo-Körös, Linearbandkeramic) and the late Palaeolithic (Marcel Otte, Paleolithic Continuity Theory).
