ABSTRACT
Human demography research in grounded on the information derived from ancient DNA and archaeology. For example, the study on the early postglacial dual-route colonisation of the Scandinavian Peninsula is largely based on associating genomic data with the early dispersal of lithic technology from the East European Plain. However, a clear connection between material culture and genetics has been lacking. Here, we demonstrate that direct connection by analysing human DNA from chewed birch bark pitch mastics. These samples were discovered at Huseby Klev in western Sweden, a Mesolithic site with eastern lithic technology. We generated genome-wide data for three individuals, and show their affinity to the Scandinavian hunter-gatherers. Our samples date to 9880-9540 calBP, expanding the temporal range and distribution of the early Scandinavian genetic group. We propose that DNA from ancient mastics can be used to study environment and ecology of prehistoric populations.

En los últimos años se publicaron numerosos trabajos acerca de los potenciales beneficios del consumo de gomas de mascar sobre la salud bucal, especialmente en lo refernete a caries dentales. Una revisión de la literatura mundial sobre el tema tiende a considerar que el chicle sin azúcar masticado después de la comida tendría un efecto beneficioso, si bien existe consenso de continuar las investigaciones acerca de su eficacia como potencial medida preventiva de caries (AU)
