Why did Asia and America separate? How did humans enter the North American continent?

When watching adventure programs, you can often see naked aborigines who may be painted with colorful paintings. These programs are usually filmed in the United States or Australia.

Many people may be curious, why are some people willing to live a life close to primitive people when modern society is highly developed?

In fact, 500 years ago, this group of people was indigenous, and their history can even be traced back to the human stone age tens of thousands of years ago.

Until the later era of great navigation, the arrival of modern people completely broke their lives. Most of them died of unknown bacteria, a few accepted the fact that modern civilization was assimilated, and a few survived, still retaining their original way of life. Fortunately, it gives modern people the opportunity to intuitively understand and study indigenous people.

Half pirates and half businessmen are speculators. Since the fall of the Western Roman Empire in 476, Italy has been in a state of disintegration, with large and small city-states, such as Venice, Florence and Genoa.

With its unique geographical location and the temperate inland sea of the Mediterranean Sea, the Italian Peninsula has become the main geographical center of trade and commerce, and the coastal city-states of Italy have prospered and created a lot of wealth.

145 1 In the autumn of, Columbus was born in Genoa, a country adjacent to the sea. Genoa was one of the few maritime hegemonic countries in the Mediterranean.

As a people who live by the sea, the most common business they do on weekdays is to organize a group of people, take a pirate ship and engage in looting. Merchant ships traveling between the east and the west have a headache for this, but after robbing others, they become comprador businessmen in the streets.

Columbus grew up in such an environment. It can be said that his character has both the adventurous side of pirates and the treacherous side of businessmen. Such complicated personality characteristics prompted him to become the "first person" to discover the new continent.

▲ Genoa is a coastal city in Italy. In the Middle Ages, it was a maritime hegemonic country as famous as Venice.

Driven by capitalism, great sailing is the inevitable result. 15th century is a corner in the course of human history: the dark Middle Ages ended, and the subsequent Renaissance swept across Europe, and the scientific revolution and religious reform loomed. Great navigation was also born in this great era.

Genoa is a powerful maritime city-state, and so is Venice. For centuries, these two can be said to be sworn enemies, so-called peer rivals.

Due to geographical reasons, Venice is located in the east of the Italian peninsula, which makes Venice in a trade monopoly position all the year round. Silk, tea, spices and other articles from India and China are taxed in Ottoman Turkish ports, in Venice and finally in Western Europe.

Tea, which was not very valuable in China, rose several times in Europe, and the silver in Europe flowed to the east, resulting in a shortage of silver in Europe.

Columbus was an adventurous man since he was a child, and he liked reading The Travels of Marco Polo. He believed in the famous theory of the earth circle at that time.

Although this theory was not perfect at that time, it opened Columbus' brain hole. Since our planet is a sphere, we can certainly cross the Atlantic Ocean to the East.

If it succeeds, Gea won't have to look at Venice's face again.
