Yersinia Pestis - the most feared disease in human history - has long been thought to be the Plague of Justinian in 541 AD. But new studies of ancient DNA have revealed traces of Yersinia pestis dating back more than 5000 years.

In this episode of The Ancients, Tristan Hughes is joined by Laura Spinney to explore the origins of prehistoric plague. How did this disease emerge in the Neolithic world? Where did it come from? And could it have triggered a Stone Age collapse which signalled the dawn of the Bronze Age in Europe? Discover how this deadly pathogen reshaped entire Stone Age societies, long before the advent of written history.
