Why are black people in the United States not as black as black people in Africa?

Anyone who has been to the United States will find that compared with black people in Africa, black people in the United States are slightly whiter. This is because most black people in the United States are of paternal Europa ancestry. is a product of slavery. According to data from the U.S. gene bank, about two-thirds of black people in the United States are of mixed race, and the average is about 16% of Europa genes. Therefore, black people in the United States have lighter skin and more body hair. In addition, most mixed-race Americans have a higher probability of becoming white. What is particularly mentioned is that, unlike Obama, black Americans who marry white people are more likely to have children who become white, because black people have white genes. of.

Secondly, it is caused by the intermarriage between blacks and whites. Because according to the latest interpretation of evolutionary theory, changes in the genome of organisms are caused by mutations, not the gradual changes we usually think of. However, the time required for genetic mutation is definitely longer than the hundreds of years it took black people to arrive in the Americas. Therefore, we usually think that latitude and light are not the decisive factors for the physical characteristics of black people.

Furthermore, black people in the United States immigrated from Africa in the past, and the method of immigration was mainly obtained through the historical slave trade. Therefore, black Americans are genetically related to black Africans. Same race. Due to the barren land in Africa, most black Africans are thin, malnourished, and have large heads and stomachs. However, the living conditions of black Americans are relatively better.

Due to the increasing frequency of intermarriage between yellow, white and black Americans in recent years, black Americans have also been genetically modified by other ethnic groups to a certain extent. They have also made great contributions to the economic and cultural development of the United States. In fact, the earth is a big family. Black or white skin color does not mean anything. Mutual equality and freedom are what we ultimately pursue.
