Their languages are divided into four categories: Khoisan, Niger-Congo, Bantu and Nile-Sahara. Because people in sub-Saharan Africa are mostly black, Africans often refer to black people. Sometimes Africans include Arabs in North Africa and Caucasians in South Africa.
Among them, the Sahara desert is the largest desert in the world. East Africa also has the largest rift zone in the world. Other deserts are mostly distributed in southern Africa and the Horn of East Africa. Within the latitude of north and south 15, most of them are vast tropical grasslands, and the Congo basin and the Gulf of Guinea are tropical rainforests.

The birthplace of mankind
Africa is the continent with the longest history of human civilization. Since Darwin put forward the idea that human beings originated in Africa in 187 1, the world archaeological community has provided a lot of physical evidence, indicating that Africa, especially East Africa and South Africa, may be the earliest birthplace of human beings.
There are five stages in the evolution from Australopithecus to modern humans: Lamarckian, Australopithecus, Homo erectus (Homo erectus), early Homo sapiens and late Homo sapiens. These fossils have all been found in Africa, and their evolution process is more continuous than other continents, and the time of each stage is earlier, which indicates that Africa is probably the birthplace of human beings. [2]? After the rise of modern molecular biology, it is further proved that all modern homo sapiens originated in Africa.
Modern molecular biology uses genetic tools to analyze maternal mitochondria and paternal Y chromosomes of African, European and Asian races. It is found that ancestors of different races walked out of Africa 50,000-70,000 years ago14.3-144,000 years ago.
