A couple of years ago we published genetic data from middle Neolithic megaliths located in Falbygden, we called the samples gok002 and gok004 (Skoglund et al. 2012 and Skoglund et al. 2014). The scope of these papers were to demographically explore the Neolithisation, and they finally proved that the Neolithization of Europe was driven by migration. Now this data has found new use in an interesting study by our Danish and French colleagues.
Rascovan et al. has re-examined the data, and found a strain of Yersinia pestis in it. This is the oldest indication of that bacteria in Europe so far, and it seems to be basal to all other strains known from the continent. The authors use the results to speculate on wether a middle Neolithic decline was caused to some degree by diseases. It is good to see our old data finding new exciting use.
