The great Ice Age, or Glacial Period, was a time when 6 great mass of ice down gradually from the north and covered parts of the world. It came down over North America, and a similar mass of ice came down over northern Europe and western Siberia.
When did this happen? It is thought that it began nearly 1,000,000 years ago. When did it end? In the United Kingdom, it may have ended only a few thousand years ago, and in some parts of the world, it still has not really ended. The glacial period still remains in Antarctica and Greenland.
Millions of square miles of Central Europe were buried under. a great creeping ice sheet reached as far south as London, Romania, and the southern tip of Russia.
When the Ice Age came, animals from the Arctic migrated southward in front of the glaciers. Animals that could not stand the new, colder conditions were forced to migrate to warmer regions or die out. Native wild animals now only found in America are merely a remnant of the many varieties of beasts known to have lived there before the Ice Age.
Man, of course, was able to adapt his life to the colder climate. This probably helped him gain intelligence because more difficult living conditions made him use his mind and ingenuity in order to survive.
Plantlife also moved south in front of the glaciers and moved back again as the glaciers melted. But many kinds of plants simply died out.
How Did The Animals From The Ice Age Die?
As moisture in the air increased, grasslands turned to bog and ecosystems collapsed, eventually causing species like the woolly mammoth, giant sloth, and saber-toothed cat to die out. Between 15,000 and 11,000 years ago
