The culture pursued by a nation will lead to a change in the genetic characteristics of a nation, that is, the nation is naturally affinity with the cultural tradition, even if the society has undergone a radical change. For example, a nation that has experienced a long period of centralization in a society is inherently fond of centralization, even in a democratic society.
Is this true?
Theoretically, this is most likely true. For example, China used to respect Confucianism, and filial piety in Confucianism is a very important value, so in society, filial piety people will be affirmed by more people, and they can also get more survival resources, and it is easier to get married and have children, and it is easier to pass on the genes of filial piety; On the contrary, people who are not filial will be rejected by the society, and it will be more difficult to pass on their genes, after thousands of years of reproduction, there are more and more people with filial piety genes in the population, and the cultural tradition of filial piety is engraved in the biological DNA of our nation.
In practice, we can also see that the countries that can become developed, or countries with similar cultural traditions to the West, such as Japan, or countries that have been deeply influenced by Western culture, such as South Korea and Singapore, and other countries are developing countries. Whether a country is developed and rich or not depends on many factors, but I think that the cultural tradition engraved in the biological genes of the main ethnic group of the country is also a very important part.
