This popular-science book tells the story of one of the most important, but least known major archaeological sites in Europe: Doggerland. Few people know that the beaches along the North Sea lie on the edge of a vast lost world. A prehistoric landscape that documents almost a million years of human habitation and lay dry for most of that time. Doggerland is where early hominids left the first footprints in northern Europe, more than 900,000 years ago. Later, for hundreds of thousands of years, it was the scene of ice ages. A world of woolly mammoths and rhinoceroses, horses and reindeer and the successful Neanderthals who hunted them, including Krijn: the first Neanderthal from Doggerland. At the end of the last Ice Age, the first modern humans also left their traces here, including the famous Leman-and-Ower-Banks spearhead - the first documented Doggerland find - and some of the oldest art in the region. With the onset of the Holocene, our current era, Doggerland's inhabitants were increasingly confronted with climate change and rising sea levels, just as we are today. The Mesolithic hunter-gatherers lived in a rich, but constantly changing world - to which they successfully adapted. Ongoing submergence and a huge tsunami around 6150 BC marked the beginning of the end. A few centuries later, the last islands disappeared under the waves and with them the story of Doggerland was lost in time. This book brings this vanished world back to the surface.
