Where did the first Americans come from?

More than 200 years ago, the United States was a British colony. America was founded by a group of lawyers, so the first American should be British.

China or foreigners came first on the earth?

If we want to explore the origin of China people, the origin and evolution of human beings is an unavoidable topic. After archaeological excavations, the scientific community now believes that the earliest ancestor of mankind is Australopithecus, which was born about 6 million years ago and lived in the southern part of the African continent.

A branch of this ape developed into a more advanced homo habilis about 6.5438+0.8 million years ago. By 6.5438+0.5 million years ago, Homo erectus appeared. They can use fire and make complex tools, and one of them is from Beijing. Early Homo sapiens was born 250,000 years ago, with Martin and Ding Cun as the representatives. By 40 thousand years ago, the evolutionary history of mankind had entered the stage of late Homo sapiens, one of which was Neanderthals.

One of the criteria for dividing human evolutionary history is based on various fossils that have been discovered.

1987, American scientists made an experiment. By testing the DNA of women from different parts of the world, they found that African women have the most genetic variation. So what does this mean?

According to the principle, the more variation, the longer the history. Scientists speculate that the history of modern people in Africa can be traced back to 200,000 years ago, while the history of modern people living in Eurasia is about 1.3 million years.

Then, experts come to the conclusion that modern people in the world may have an ancestor. This ancestor may be an African woman named Eve 200,000 years ago.

Scientists believe that about 6.5438+0.3 million years ago, Eve's descendants went out of Africa one after another and began to spread all over the world. These descendants of Eve did not integrate with the "aborigines" when they came into contact with humans in other regions, but completely replaced them.

This is terrible, which means that the primitive ancestors of China people today are not "Beijingers" or "cavemen", but African humans who came to China in the early days.

The origin and history of America

The origin and history of the United States is:

1. Origin: The original inhabitants of North America were Indians.

2. History: The United States was originally inhabited by Indians. /kloc-At the end of 0/5, Spain, the Netherlands, France, Britain and others immigrated here one after another. 13 Before the 8th century, Britain established13 British North American colony on the Atlantic coast of the United States. 1775, the American people broke out the war of independence against the colonial rule of the British Empire.

1776 On July 4th, the Second Continental Congress was held in Philadelphia. George Washington was the commander-in-chief of the Continental Army and issued the Declaration of Independence, announcing the formal establishment of the United States of America. 1783 At the end of the War of Independence, Britain recognized the independence of 13 colonies. 1787, the constitution of the United States was passed, and a federal state was established.

topography

The terrain of the United States is changeable, with high terrain in the west and low terrain in the east. There are coastal plains on the east coast, which are wide in the south and narrow in the north, extending to New Jersey and Long Island, and there are also some glacial sedimentary plains. Behind the coastal plain is a hilly area with undulating terrain, extending all the way to the Appalachian Mountains in North Carolina and New Hampshire, with an altitude of 1, 830 meters.

To the west of the Appalachian Mountains is the central plain of the United States, with relatively flat terrain. The Great Lakes and the Mississippi River Basin, the fourth largest river in the world, are also located here. To the west of the Mississippi River, the topography of the internal plain began to rise, and finally it entered the great plain with a vast area and few topographical features in the central United States.

Were the ancestors of Americans British?

The ancestors of America were not entirely British.

Americans were immigrants from Europe during the colonial period. But the American continent was not only colonized by Britain. For example, Spain was one of the countries that colonized the American continent in the early days.

Only by various means did the United States annex the land originally occupied by other European countries. For example, due to the decline of Spain, the United States won the war with Spain at a small cost, and many Spanish colonies, including Guam, have since belonged to the United States.

About early English colonists;

1606 The first batch of British colonists who arrived in America was actually only 105, of which the proportion of free people was very small, and most of them were indentured slaves. They traded their freedom for air tickets to America for several years. All hail the king, the first British colony in America, was named Jamestown.

Even if those lucky colonists didn't die on the road, the death rate after landing on the American continent was still high. Ironically, some colonists accepted the help of native American tribes in order to survive.

Where did Americans immigrate from?

The earliest inhabitants of America were Indians. More than 40 thousand years ago, the ancestors of Indians arrived in North America through Asia, and Indians were regarded as the primitive people of the United States. Today, about 654.38+50 million Indians live in the United States and Canada. Ten thousand years ago, another group of Asians moved to northern North America and became Eskimos. The first white people to come to America were vikings.

African-Americans were16th century when the United States became a European colony. From 16 to 19, European colonists transported a large number of black slaves from Africa to America, and more than half of them were transported to the present United States.

Extended data:

Americans are people who have British and American citizenship, or whose parents are of American descent. The United States is a multi-racial country, with four major races, namely, white, black, colored and Asian, accounting for 75%, 13%, 7% and 5% of the total population respectively. Asians are about120,000, mainly Indians and China. ? The human development index is 0.902.

The United States was the first place where Indians lived. At the end of 15, Spain, the Netherlands, France and Britain immigrated here one after another. 13 Before the 8th century, Britain established13 British North American colony on the Atlantic coast of the United States. 1775, the American people broke out the war of independence against the colonial rule of the British Empire. 1776 On July 4th, the Second Continental Congress was held in Philadelphia.
