The video below is actually a remake of a 2008 animation made by NASA's Horace Mitchell. In 2008 he
The video was recently remade by James O'Donoghue,a planetary scientist at the Japan Aerospace Exploration Agency; he previously worked at NASA. He played the video in higher resolution, slowed down the animation and added a tracker that shows how much water has disappeared from the Earth.
Video reveals important informationabout the vast unexplored seabed of the ocean, and also about human evolution. During the Last Glacial Maximum, from 26,000 to 19,000 years ago, sea levels were about 125 meters below present levels. This is due to the fact that a huge amount of ocean water was “locked” in glaciers from Antarctica to Greenland, as well as in northern North America and Europe.
This led to the appearance of shallow land bridges between continents and islands. In early human history, they were used to migrate around the world.
It turned out when the Bering Bridge actually appeared. He connected Asia with America
So, our ancestors migrated from the continentEurope to the UK via land bridges, as well as from Alaska to the Far Eastern region of Russia. Additionally, the land connecting North and South America was wider, making it easier to travel between the two continents.
