A new study refers to the presence of yersinia pestis in Europe during the late neolithic/early bronze age:

If these hypothesis of a y.p. as a major trigger of the cultural and demographic changes at the end of the neolithic can be verified, comparisons with the 14th c. crisis will be of some interest. Prehistoric archaeology should check for indications e.g. of wheather extremes, the reorganisation of land use practices and increasing soil erosion in the time before the outbreak of the plague. Furthermore it should be tested, whether the health of the population was probably weak at that time. However, by now neither the chronological nor the spatial framework of this postulated outbreak is clear.
