What are the benefits of racial diversity?

China's hybrid rice is world famous. In corn and other crops, the hybrid method is used to cultivate new excellent varieties, which greatly improves the yield of crops. This principle is biologically called "heterosis".

Heterosis principle is widely used not only in botany, but also in zoology, thus cultivating many excellent new varieties. For example, horses and donkeys mate to produce mules, carp and crucian carp mate to produce goldfish, and tigers and lions mate to produce liger.

There is a similar pattern in demography. Inkin marriage is a disproof, and positive examples abound. According to legend, Confucius was born in the wilderness by a 70-year-old wise man (his father) and a young girl (his mother). Humans were originally married in groups, and they did not shy away from intimacy when mating. Later, the facts tell people that consanguineous marriage is extremely harmful, and it cannot be compared with and compete with the advantages of marriages of different lineages. In the process of biological evolution of survival of the fittest, people gradually abandoned consanguineous marriage. In reality, descendants of distant relatives are often more likely to have excellent physical fitness, and "hybrids" and hybrids are one of them. The famous singer ChristianRandPhillips is one of them, and his boss is related to the inheritance of his American father.

Therefore, from the perspective of population eugenics and even national development, in modern society, we should have a higher and deeper understanding of population mobility. Normal, reasonable and moderate population flow is not only the need of economy or politics, but also the need of improving national quality. In the extensive flow of population, people from different regions, different lineages, different characteristics and advantages, different cultural backgrounds and even different races have more contact opportunities, and the probability of intermarriage between them has also increased, which is conducive to the healthy birth of the population and the improvement of the individual quality and overall quality of the population. An all-round open area, with large population mobility, free deployment of labor force and rapid economic development, is also conducive to the improvement of population quality.

However, at present, there are still many policies and regulations that restrict the free flow of population, hinder the free deployment of labor force and affect the prenatal and postnatal care of the population, which need to be reformed urgently. The feudal Garbo-style strict household registration system is a big problem, which has become a big shackle that hinders the rational flow of population and delays the process of urbanization. In many places (especially some rural areas in the mainland), due to the influence of traditional habits or unreasonable human feelings, people's marriage scope is extremely narrow, which is extremely unfavorable to the improvement of population quality. In Xinjiang, there is a place called Dabancheng. Historically, people there are very healthy and beautiful, and they are famous for their beautiful women. Because it is a relatively isolated oasis in geography, people's marriage scope is narrow, consanguineous marriage is serious, and the rate of birth defects is increasing. Hundreds of years have passed. According to a survey, 30% to 40% of the population here are born with disabilities, among which intellectual disabilities are the most, which has become a miserable world. Therefore, reducing man-made obstacles and promoting the rational flow of population should arouse the great attention of Chinese people, especially those in power!

In human culture, there is also a kind of "heterosis". There are two major cultural systems in the world: western culture and eastern culture. Some people emphasize that western culture is advanced, while others insist that eastern culture is superior. In fact, absolute judgments are often biased. All cultures should learn from each other, learn from each other's strong points, achieve qualitative improvement and breakthrough in collision and blending, and make continuous progress and transcendence. One of the most typical examples in this regard is the United States and the other is Japan.

The history of the United States is very short, and it is a country established by the development of immigrants. 1492 After Columbus discovered the new American continent, people of all kinds from European countries drifted to this wild land for various reasons and with various ideals and beliefs. They rarely have a complete tradition, and those things are left on distant European continents and islands. The British, French, Spanish, Portuguese, Dutch, Irish, Jews, African blacks and Asians who came here later, together with the local indigenous yellow-skinned Indians, have different origins and cultures. They collided, exchanged and merged with each other in their work and life, forming an excellent American nation and a cultural America suitable for their historical soil. From a cultural point of view, this result is not accidental.

Japanese traditional culture is deeply influenced by China culture and belongs to the oriental culture with strong agricultural color. Oriental culture has a long history and is profound, but in modern times, traditional oriental culture has become complacent, such as mature and rotten peaches, waiting for a new life. At the same time, western industrial culture is like a newborn calf, and the sun is shining. It challenges and impacts the oriental culture with an aggressive posture, and both China and Japan are facing national crisis and cultural crisis. The Meiji Restoration in Japan was a success. It introduces and learns western culture through the transformation of superstructure such as social system. At first, it was mainly "equipment (technology)". After World War II, the United States grafted the "system (democratic system)" of western culture. The reason why Japan can have today's glory is amazing and envied by the world. Cultural reasons are nothing more than that. Japanese people's study of western culture is all-round and three-dimensional, but it is not completely westernized. Today, there are still many traditional traces of Confucian culture in Japan's political life, economic life and cultural life. As a typical example, Japan shows the great role of eastern and western cultures in integration, tolerance and complementarity. Isn't this a "hybrid" of cultures?

Reminiscent of the current "center", that is, economic construction, the advantages of "hybridization" are also reflected everywhere. In the economic system reform, there are many opinions and arguments, for example, in the modern economic operation, is it better to adopt the planned mode or the market adjustment mode? In fact, only the combination and coordination of the two can maintain and promote the rapid and stable development of the economy. From the philosophical point of view, too absolute existence lacks stability, and there can be no complete planned economy or absolute market regulation in reality. For example, in the property right system, history and practice have proved that simple public ownership and complete private ownership are difficult to implement, and it is also difficult to achieve the effect of high-speed, high-quality and efficient economic development. Good and effective cooperation of various ownership systems and modes of operation can better maintain and promote economic development, which can also be regarded as "mixed advantages".

China's traditional political culture pays more attention to the golden mean, and the Taoist cloud says, "Yin and Yang are born when they are combined, and they are dead when they are separated." Aren't these all related to the principle of "mixed advantage"?

From this point of view, in real life, the word "hybridization" is quite weighty. It plays a great role in economic construction, population eugenics, cultural construction and political life ... in many human activities.
