Scientists say that human beings originated in Africa, so why aren't we black?

At present, there is no reproductive segregation on earth (blacks and whites can still get married and have children). In fact, all human beings are one species. Intuitively, it is natural to think that all human beings on earth come from the same ancestor and the same place. In fact, biologists and anthropologists think so.

In this case, the origin of mankind is a question that needs to be answered. It is generally believed that humans originated from ancient forest apes. Later, with the change of living environment, some Australopithecus had to walk upright and use tools to feed and survive, thus gradually evolving into humans. Finding the birthplace of human beings is as simple as finding the oldest fossils in the most possible place.

Since 1950, a large number of human fossils dating from 2 million to 4 million years ago have been found in East Africa. So since 1960s, Africa has been recognized as the birthplace of mankind in the world. Even now, when people no longer oppose the theory of evolution, some people disagree that it originated in Africa. Some people say that human beings can't have originated in Africa, because if their ancestors were black, even if some people have different skin colors, they will become black.

If you look at the powerful genes of black people today, they absorb all skin colors. Unless all ancestors from Africa become albino, yellow or brown at the same time, they must also produce all genetic mutations in their children to produce non-black offspring. Explanation of skin color How do you explain skin color? Well, it's very simple. This is the result of differentiation. This is consistent with Darwin's theory of evolution that primitive people are not black. The formation of black people is due to the hot weather in Africa. Under the irradiation of sunlight, genes of other skin colors are produced, leaving the genes of dark skin that are most suitable for the environment. The same is true of yellow and white.
