Expansions of steppe pastoralists associated with the Yamnaya and Corded Ware cultures into Late Neolithic and Bronze Age Europe transformed the ancestry of human populations (43, 45, 46). To test whether dog ancestry was similarly affected, we analyzed a 3.8-ka-old dog from the eastern European steppe associated with the Bronze Age Srubnaya culture. Although its ancestry resembles that of western European dogs (Fig. 1C and fig. S10), it is an outlier in the center of PC1–PC2 space (Fig. 1B). A Corded Ware–associated dog (4.7 ka ago) from Germany, hypothesized to have steppe ancestry (14), can be modeled as deriving 51% of its ancestry from a source related to the Srubnaya steppe dog and the rest from a Neolithic European source (data file S1) (30). We obtain similar results for a Bronze Age Swedish dog (45%; 3.1 ka ago), but not a Bronze Age Italian dog (4 ka ago).
Despite this potential link between the steppe and the Corded Ware dog, most later European dogs display no particular affinity to the Srubnaya dog. Modern European dogs instead cluster with Neolithic European dogs (Fig. 1B) and do not mirror the lasting ancestry shift seen in humans after the pastoralist expansion (Fig. 3A). Earlier and additional steppe dog genomes are needed to better understand this process, but the relative continuity between Neolithic and present-day individuals suggests that the arrival of steppe pastoralists did not result in persistent large-scale shifts in the ancestry of European dogs.
