At the bottom of the North Sea, between the United Kingdom and Scandinavia, lies Doggerland—the once thriving home of thousands of Mesolithic humans that sank beneath the waves as glaciers melted some 8000 years ago. This week, scientists set off across the North Sea to create a 3D map of this Colorado-size plot of land and search the seabed for artifacts and ancient DNA, The Guardian reports. The 3D map will reveal Doggerland’s hills, rivers, and coasts, which could help pinpoint settlements of the hunter-gatherers who flourished there for 6000 years. A specialized ship will also take core samples from the sea floor in hopes of finding human relics and sources of plant and animal DNA to envision a lost ecosystem.
