The appearance of black Americans is obviously different from that of black Africans. What is the reason?

It is said to be black, but black people in the United States and black people in Africa have obviously formed different "racial" differences. The economic level of the United States is more than one level higher than that of Africa, so the living standard of blacks living in the United States is much higher than that of Africans. So you can see a lot of fat black people in America, but what you can see most in Africa are thin children and women.

Their differences in mental outlook are obvious because they face different social pressures. What black Americans face is that they have no human rights, are not accepted by white Americans, and can't get a good social welfare guarantee, but these are all for better interests after they have no worries about survival. Africans, not to mention human rights, may be willing to be servants as long as they can survive, and their minerals have long been plundered by capitalists.

Moreover, the slave trade has been going on for nearly 300 years. Even if American society looks down on blacks, there will always be a few people who will integrate with blacks. Today, the skin color difference between black Americans and white Americans cannot be changed, but their body shape may be beyond doubt. Americans' favorite tall nose has also been "inherited" by African Americans. Although most of them have become big noses, they are also very different from black people on the equator.

Because African blacks need a good cooling system, it is not uncommon to have large pores, and the oxygen content at the equator is different from that in North America, and the structure of the nose is also different. Finally, the hairstyle. The hairstyle of black Americans is to show their individuality, while the hairstyle of black Africans is not to interfere with their lives, but also because they are too lazy to wash it, which is enough to form different black "nations".
