New research has found that from 20,000 to 7,000 years ago Great Britain was surrounded by a vast area of dry land that reached as far as Denmark.

New research has found that from 20,000 to 7,000 years ago Great Britain was surrounded by a vast area of dry land that reached as far as Denmark.

The research suggests that the populations of these drowned lands could have been tens of thousands, living in an area that stretched from Northern Scotland across to Denmark and down the English Channel as far as the Channel Islands.

As the ice age ended and sea levels rose, this land was slowly swamped and engulfed by the North Sea.
