Over 2.5 million years ago the first humans arrived at the Americas from Asia in the beginning of the Great Ice Age. The Ice Age held tons of water and expanded across the continents causing animals to migrate to other parts of America. Dated as far back as the 1590’s the first Americans started to populate Beringia along with the animals. Beringia often referred to as Bering Land Bridge, is a region that is located between “Siberia on the Asian continent and Alaska in North America, that connects present-day northwestern Canada and northern and western Alaska, US.” During the Ice Age, Beringia was a large dry grassland that was perfect for the animals over ten thousand years ago. These animals include the giant bison and the woolly mammoths.
