What ethnic group are black people?

Black race, that is, black race, also known as black race, black Australian race and equatorial race, is a theory of human classification, which is divided according to the genetic characteristics of constitution. Black people generally have dark skin, wavy or curly hair, dark eyes, wide and flat nose, low or medium nasal root, small nasal process, large nostril diameter, lip process, wide mouth, thick lips, and little beard and body hair. The racial classification of blacks mainly includes Sudanese blacks, Bantu blacks (both of which account for the vast majority of African blacks), Koisan blacks, Cuscito blacks (mixed-race) and Australian aborigines. Before and during the Middle Ages, they were mainly distributed in sub-Saharan Africa. Later, because of imperialism and mercantilism in European countries, a large number of blacks were forced to be sent to South America and North America as slaves.

Negro was once used as a name for a black man in English, but it was originally a "black man" in Spanish, but it had a strong contempt. Some black groups with a long history still use this word, such as the African American University Foundation. The common name of American media is: African American. Black is acceptable, and nigger is completely derogatory. However, some black people also use this word to address each other.
