Towards the end of the fourth millennium BCE the construction of megalithic tombs across northwestern Europe came to an end. At the same time there was a huge decrease in population sizes. This pivotal time is known as the 'Neolithic decline.' Experts have long argued for what may have caused this change with competing ideas including the plague and overfarming. A new DNA study at a megalithic tomb in the Paris Basin might just be able to solve this ancient mystery.
