Among the many places people have lived that ended up underwater, there was once a big stretch of land between Britain and continental Europe, from northern France to Denmark. This area is now called Doggerland. We had no clue about it until the early 20th century, but now we regularly find more artifacts from Doggerland. Neanderthals lived there, and modern humans later on, as well as plenty of animals and forests. But what happened to Doggerland? There are plenty of hypotheses, which might have all been true over time, as the land was cut up into pieces before it was completely consumed by the North Sea. Somehow Britain and Ireland survived, but who knows what may happen in the next few thousand years? This video is only eight minutes long; the rest is promotional.
