The World before the Opening of the Atlantic
At the start, of the Ice Age, earth's climate became intensely cold.
Large amounts of water froze into huge, moving sheets of ice called
glaciers. Abruptly, in c. 38,000-10,000 BC, the Paleo- Indians moved
as nomadic bands across to the Americas in response to the rhythm of
the seasons and the availability of the resources. Thereafter, no one
knows exactly when or how people crossed into North America. Soon
afterward, in c. 5000 BC, communities in Mexico cultivate (prepare)
corn. Corn is storable for long periods of time, it can be grounded into
flour, and it easily turns into surplus for future use. Then, in c. 3000
BC, the Algonquian group begins to spread across Long Island. Also,
they survived by hunting and gathering plants. Promptly, in c. 2600
BC, The Great Pyramid is built at Giza, Egypt, as the tomb for the
pharaoh Khufu. Khufu's pyramid is the largest pyramid in the world.
Just then, in c. 1200 BC, Olmec begin their civilization in
Mesoamerica. The ancient Olmec civilization is now considered to be
one of the earliest great civilizations in Mesoamerica. Suddenly, in c.
1350, new ideas begin to spread through Europe during the
Renaissance. Additionally, the period of European history referred to
as the Renaissance was a time of great social and cultural change in
Europe. Lastly, in 1492, Christopher Columbus and his crew reach the
Americas on October 12. Eventually, he made four voyages to the
Americas, the first voyage begins in 1492, which led to the discovery
of America. In conclusion, many Native American societies developed
across Mesoamerica and South America.
