Isn't Africa all black?

Africa is the region with the most complex ethnic composition in the world. Most ethnic groups in Africa belong to black people, and the rest belong to white people and yellow people.

By 20 16, the population of Africa will be about1200 million, and the world population will be 7.35 billion (20 16), ranking second in the world after Asia. The average annual population growth rate in Africa is 2.3%, much higher than that in Asia (1%), and the population growth rate in sub-Saharan Africa is higher than that in North Africa. There are many poor people, which are expected to reach 2 billion by 2050.

Extended data:

According to the differences in physical characteristics, the races in the world in the past were roughly divided into three major races, namely, Mongolian race (yellow race), Caucasian race (white race) and black race (black race).

Others argue that Australians (brown people) should be separated again. There are also some transitional races between these major races, such as Ethiopians and South Indians between Negro and Caucasians, Southern Siberia and Urals between Caucasians and Mongolians, Polynesians and Thousand Islands people between Mongolians and Negros.

With the development of human history, the ability of human production activities is improved, the ability to control nature is enhanced, social factors are gradually strengthened and natural selection factors are gradually weakened, human communication is increasingly frequent, and the phenomenon of mutual blending among human groups is more and more extensive, almost everywhere in the world. Therefore, there are almost no absolute purebred in the world.
