Spanish immigrant mother and daughter

This theory has been around for a long time. Now it is generally believed in the west that all continents originated in Africa. Tens of thousands of years ago, due to climate change and food shortage, there was a great migration, and humans traveled to all parts of the world in batches. The arrival of African immigrants led to the extinction of local original races, such as Neanderthals, such as some ethnic groups in Asia.

The historical evidence of migration is not only that the mitochondrial diversity of African women is much higher than that of women on all continents (mitochondrial inheritance is only passed from mother to daughter, but not from father to offspring, which is different from chromosomes), but also that native Americans, before the arrival of the Spanish in the15th century, 100% was O-type blood, indicating that type A and type B blood did not appear during migration.

In Gould's "Since Darwin-Meditation on Nature", at the beginning of last century, some European scientists hoped to prove that whites were superior to blacks through the great differences in external characteristics (body hair, bones, etc.). ) Between blacks in childhood and adulthood, while whites are relatively small, but they find that if they accept this argument, it means that Asians are better than whites and women are better than men.

As early as 1960s and 1970s, the difference of IQ was proved that the acquired environment was much more important than the innate one, which was proved by IQ tests of adopted children of different races. The differences between different races in intelligence and physique are only relative, but as far as human evolution and development are concerned, they are only minor differences.

And our country is more willing to support the multi-point origin of human beings, the reason is of course to prove that Asians are smarter.
