This set of thought-provoking papers is the result of a 2018 workshop on the impact of the 'genetic revolution' on archaeological theory building, one of a series of publications, meetings and conference sessions aimed at fostering interdisciplinary dialogue, and dealing with the almost impossibly large influx of data from archaeogenetic research and the issues it raises (see, amongst others, Scharl & Gehlen ed. 2017; Manolakakis et al. eds 2017; Meller et al. eds 2017; Samida & Feuchter 2016). We are only now beginning to get a handle on what the results imply for our views of past societies and ways of life (for the Neolithic, see e.g. Vander Linden 2016; Furholt 2019; Hofmann 2015, 2016). But while they have caused considerable uproar, it is fair to say that archaeogenetic data have not created new problems, but rather brought into sharper focus fault lines which have existed in our discipline for a long time, albeit in varying intensities in different countries. As outlined in the papers collected here, these fault lines concern the sorts of pasts we think are important to write about, the nature of interdisciplinarity and what this means for the craft of doing archaeology, and our relationship to a wider public and the implications of the images of humanity we create. All these issues are as yet unresolved. Beginning with the pasts we write about, many authors have highlighted that archaeogenetics tend to reproduce tropes that are dangerously close to
