Americans are descended from those peoples. What's the ratio?

"1606, the king of England officially approved the applications of some nobles, gentlemen and businessmen and decided to colonize North America. When the first English Puritans arrived in Jamestown, Virginia on 1607 and Plymouth, Massachusetts on 1620, autumn and winter came. Thanks to the friendly reception of the local hospitable Indians, they were given food such as turkeys and pumpkins, and they survived. Indians also patiently and meticulously taught them the techniques of planting corn, pumpkins, tomatoes and hunting.

In this way, these British immigrants survived in this' new world' and the corn planted in North America for the first time was harvested. These British immigrants celebrated this day with great joy and called it "Thanksgiving Day". But they thanked God for the gift, not the Indians. On the contrary, not long after, after a large number of British immigrants poured in, British colonists, the predecessors of Americans, turned to expel the owners of this land and plunder their land. They used various methods used by colonialists, including divide and rule, carrots and sticks, to divide and buy Indian tribes, create favorable situations, adopt the strategy of divide and rule against Indians and carry out massacres. Although the massacre of colonialists was bravely resisted by Indians, the Indians in the primitive tribal stage in the history of human development could not resist the British colonialists who had already entered the capitalist stage, so they had to fight and retreat. A series of battles of British colonists to slaughter Indians and Indian resistance lasted from 1622 to 1769.

After the founding of the United States, with the great strides of territorial expansion to the west, the conquest and slaughter of Indians by the bourgeois regime was further strengthened. After the U.S. government formally established the army, it ordered the army to March westward immediately. Since the establishment of the first regiment of the US Army, suppressing Indians has become its basic task. This brutal massacre and suppression by the regular army and militia of the United States lasted almost a whole century, from1803 (181year) to 1892. Especially in the 1960s and 1990s, with the cooperation of local militia, the US regular federal army launched more than 1000 military operations of different scales, basically completing the task of exterminating Indians. When describing this history in relevant works, william forster wrote: "When the United States violently pushed westward, southward and northward, it not only pushed out the countries that prevented it from advancing, but also cruelly crushed the resistance of the original owners of these lands-Indonesians." This cruel expulsion of Indians is one of the most shameful stains in American history, and many outstanding American democratic leaders also actively participated in this action at that time. "

One of the "many outstanding democratic leaders in the United States at that time" who actively participated in the brutal expulsion of Indians was Thomas Jefferson, the main drafter of the American Declaration of Independence and the third president of the United States. He put forward the theory that "all men are created equal". 1803 After the United States bought Louisiana from Napoleon (that is, the vast area from the west bank of the Mississippi River to the foothills of Loki), a series of large-scale expulsions and massacres of Indians began during Jefferson's presidency.

What is the result of such long-term suppression and slaughter?

According to some honest and rigorous American scholars' recalculation based on historical data, from the late 1980s to the early 1990s, that is, when Columbus' 1 492' was in discovery of america, the total population of Indians living in the United States and Canada now ranged from 30 million to1billion. Just for the sake of caution, let's take the minimum figure of 30 million calculated by them as the standard. Then, in the 1970s, what was the total population of Indians who were forced to live on "reservations" in remote areas of the United States? According to American official statistics, there are less than 800,000 people.
