What makes things strange sometimes is when we see something for a long time, and it suddenly disappears. Eventually, the same thing happened with a land bridge that used to connect Britain and Europe. Thousands of years ago, Britain and Europe were connected by a bridge, Doggerland. This large area contained a variety of different natural environments; many animals and plants could be found in abundance. Humans had been present in this region for thousands of years; they had hunted animals and created shelters in places that would prove to be among the most successful in the British Isles.
According to reports, this ‘lost world’ began to disappear about 8,200 years ago, at the conclusion of the last ice age, with melting ice shifting ocean levels upward, which in turn created vast areas of marshland through the submergence of forest. About 8,200 years ago, an extraordinarily large submarine landslide happened near the northern shore of Europe, resulting in a huge tsunami that struck many parts of this area, flooding everything but a few regions that were still above water.
