The United Kingdom is a group of islands off the coast of Europe—but it hasn't always been that way.Many thousands of years ago，the UK was attached to Europe by a stretch of land known as Doggerland.And the evidence of the people who lived there is regularly found.Roughly 12，000 years ago，as the last major ice age was ending，the area that is now the North Sea was very different.Instead of water，the area had hills，wetlands and valleys full of trees.Stone Age people lived in Doggerland.They were hunter﹣gatherers who moved with the seasons and lived by fishing，hunting，and gathering food such as nuts and berries.Over time，they were slowly flooded out of their hunting grounds.Water which had been locked away in ice began to melt，drowning Doggerland.Around 6000 years ago，people were forced onto higher ground in what are today's England and the Netherlands.The evidence of the ancient people's presence can be found on the sea floor，where modern fishermen often find bones and tools that date back to about 9000 years ago.Those studying Doggerland say the climate change faced by ancient people is similar to that we have now.They say that a similar situation could affect the billions of people who live within 60 kilometers of a sea shore today if polar ice caps continue to melt at a rapid pace.
