The first Americans migrated to the Americas across a land bridge, Beringia, through the ice-free corridor around 13,500 years ago.

Most scientists believe that the first people to migrate to America came from Asia. Why did early people’s migrate to North America? Migration by Land Bridge: Scientists believe a land bridge connected Asia and North America during the most recent Ice Age.

They later gradually dispersed further South towards warmer valleys free of ice which as a result, populated both Americas.

How did human beings come to the Americas? They followed the migrations of animals over the land bridge of Beringia.

At the end of the Great Ice Age, the glaciers melted, and the water’s movement wore the ground down into shallower parts that ran into lake beds. THis is how the Great Lakes were formed as well. During the Ice Age, a land bridge was formed, which allowed for migrating and settlement on North America.

Maize [corn] and potatoes had the greatest impact, but other crops from the Americas also had success.

Corn had the biggest impact, altering agriculture in Asia, Europe, and Africa. It underpinned population growth and famine resistance in parts of China and Europe, mainly after 1700, because it grew in places unsuitable for tubers and grains and sometimes gave two or even three harvests a year.

Colonialism’s impacts include environmental degradation, the spread of disease, economic instability, ethnic rivalries, and human rights violations—issues that can long outlast one group’s colonial rule.

The EU has delivered more than half a century of peace, stability and prosperity, helped raise living standards and launched a single European currency: the euro. More than 340 million EU citizens in 19 countries now use it as their currency and enjoy its benefits.
