What were the ancestors of Americans like?

All the above statements are wrong. The United States is a multi-ethnic country, and its ancestors are widely distributed.

Let's start with the largest proportion of whites: most of their ancestors came from Britain, and a few came from France and the Netherlands;

Black Americans: Their ancestors came from the African continent. Because the United States was ruled by Britain before independence, Britain once occupied Nigeria, Niger and Guinea in Africa, and the British sold a large number of blacks from these countries to the United States. Therefore, most of the ancestors of black Americans came from Nigeria, Niger and Guinea.

Most of the ancestors of the yellow race in the United States came from China (a few were Japanese and Koreans), and the per capita GDP of China people in the United States is now the highest in the United States;

There are also native Americans-Indians, who are native Americans and lived here more than 4,000 years ago. In some states in the central United States, there are still the most primitive Indian settlements, and other Indians are distributed in cities in the western United States, such as Los Angeles, San Francisco and Seattle.
