Who are the Europeans? Where did they come from? In recent years scientific advances have yielded a mass of new data, turning cherished ideas upside down. The idea of migration in prehistory, so long out of favour, is back on the agenda. Visions of continuity now have to give way to a more dynamic view of Europe's past, with one wave of migration followed by another, from the first human arrivals to the Vikings. This pioneering book brings together for the first time the latest genetic evidence and combines it with archaeology and linguistics to produce a new history of Europe.
