Why do Koreans have big cakes and big faces?

This problem must be explained by science. To be sure, Korean pie face is mainly inherited. China people, Japanese people and Koreans all live in the East Asian environment. Although their living habits and eating habits are different, they will not affect their appearance too much. The reason why China people, Japanese people and Koreans look different under the same yellow skin and black hair is mainly due to heredity. . . Because China, Japanese and Koreans are not an ancestor at all, it is wrong for you to think that they are the same ancestor. Ancestors of Han and Tibetan nationalities (Han, Tibetan, Qiang, Miao, etc.) in China. ) belongs to the Central Plains of Asia, Koreans belong to Tungusic people in Northeast Asia, and Japanese belong to the mixed-race of Nantong Gus and Brown people. Molecular anthropology has proved that China, Japanese and Koreans have huge differences in Y chromosomes, and they are not human at all. Finally, to answer your question, Koreans have pie faces because of their Miao genes and Corea and Nefhe genes from Tunguska, which is the fundamental reason. Look at other ethnic groups in Northeast Asia, such as Mongols, Oroqen and Ewenki, who are basically pie faces.
