Which illnesses were prevalent 5500 years ago, and what were their causes? This is the question that the anthropologists from the Georg August University in Göttingen hope to answer. The subject of their studies are archaeological skeletal remains, because from the bones it is also possible to find evidence of chronic illnesses such as kidney, lung or heart disease. If they find similar bone structures in several skeletons from a single location it is possible to draw conclusions about the living conditions that prevailed there at the time the megalithic graves were built. What will the trail of the bones reveal?
