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.
All too often archaeological objects are found as stray finds. As such, they have little or no contextual information, which often makes them difficult to handle analytically and in terms of their exhibition appeal. As a consequence, they often languish un-researched in museum storerooms and there is the critical risk that such objects fall victim to the ongoing curation crisis and are deaccessioned due to a perceived lack of value. Therefore, in this paper we aim to illustrate the applicability of an extended biographical approach to such legacy material by studying the changing character of the Ulbi dagger, an Early Mesolithic flint-edged bone dagger, in its both archaeological and modern contexts. By using both a combination of traditional archaeological methods, coupled with a critical analysis of past illustrations, the dagger went from an isolated, undated, and unique object to a tool with a complex life history extending more than 9000 years. Our analysis reveals multiple stages of manufacturing and ornamentation including the presence of possible anthropomorphic figures. Use-wear analysis also allows us to address the object's likely primary function. Finally, we speculate about its deposition and discuss previously overlooked post-recovery episodes of damage and repair.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
