First, the harm of inbreeding is not as great as imagined, but it has certain benefits. For a long time, human beings have forbidden consanguineous marriage. Most ethnic groups in the world generally believe that the offspring of inbreeding have very serious genetic diseases, and some scientific evidence also points to this point. However, according to the latest research results of American biological laboratory, the harm of consanguineous marriage is not great. From a large number of historical materials, I also found that many political figures and scientific figures who had great influence at that time and even later generations were actually the products of consanguineous marriage. For example, during the Spring and Autumn Period in China, Ling Yin of the State of Chu and He, the former prospered the State of Chu for 200 years; The latter dominated in the Spring and Autumn Period, and then the fifth generation flourished. After the three tribes were divided into Jin, they remained a powerful country. Zhong Er has his own unique charm. When he was exiled, he was admired by the world. According to historical records, there are three characteristics: first, there is an old saying that Zhong Er is unique because he marries with the same surname and his son is not foreign; Second, Zhong Er didn't go to the countryside, and the state of Jin began to be chaotic, as if waiting for its return; Third, although he was exiled, his talents were abundant and loyal. Imagine that he must have his unique charm, which is incomprehensible. Another example is Bai Juyi, a poet in the middle Tang Dynasty. His parents were nephews and uncles, and Bai Juyi had few titles in poetry, which was highly respected at that time and later generations. From the perspective of world history, there are also many examples. For example, Hitler, the culprit of World War II, is said to be a descendant of consanguineous marriage, and his family itself has a tradition of consanguineous marriage. He was legendary when he stepped onto the political stage. Because of my limited knowledge, there may be many famous examples, so please list them. From the examples around us, it is recognized that many children who are married by close relatives are smart, superior to ordinary people, or unique in some ways. The above shows that even if close relatives get married, it will not affect their health and IQ. This is the first argument.
Second, consanguineous marriage has a great influence on genes. According to the Internet, there is one in America. All men have tails because of genetic problems. Under pressure, the family moved into the mountains and lived an isolated life. In order to survive, they adopted the method of consanguineous marriage to reproduce, but soon, one of their descendants was born without a tail, he set foot on the society, married and had children, but his descendants had a tail again. Another example is the Indian Twin Village reported in the latest issue of National Geographic. The previous generation had the custom of consanguineous marriage. All these facts show that inbreeding can change people's genes quickly, but it is uncertain, which shows how much influence inbreeding has on genes, and it is inbreeding that makes their genes mutate. I also urge relevant experts to pay attention to this point.
Third, mankind has always hoped to discover the mystery from the fairy tales of all ethnic groups. The reason is also very simple. It can be said that different people have different opinions, but I found that in many fairy tales, the ancestors of human beings are hermaphroditic, and their brothers and sisters are ancestors. For example, in the myths and legends of China, the ancestors of mankind, Nu Wa and Fuxi, were brothers and sisters, while the others were Greek mythology and Zeus, the god of gods. In addition, from the perspective of some customs and history, for example, most ethnic groups have experienced the stage that only Anemarrhena asphodeloides does not know their father, which cannot be fully explained by the concept of matriarchal society. Perhaps in the early days of the development of human society, some customs of consanguineous marriage still existed, but they just didn't want to make it clear. As the saying goes, women are like aunts and men are like uncles, which has theoretical basis.
To sum up, with regard to the origin of human beings, we can assume that about 200-/kloc-0.5 million years ago, a small group of apes were trapped on an island somewhere on the earth, and that on the African continent, due to floods or earthquakes, they had to marry their brothers and sisters in order to survive and reproduce, so as to avoid extinction. It is conceivable that under the extremely harsh natural conditions at that time, most of their descendants did not survive and died soon, but some improved strong people survived the fittest and constantly changed themselves. From the inside out, from the mind to the body, they have undergone great changes. After a long period of time, only when the flood receded, they already had the embryonic form of modern people. Although they have nothing, they are born strong, and in the long years to come. These wise men or leaders constantly improve themselves and adapt to the environment. About 50 thousand years ago, they finally became human.
We study this point, first, to solve the old problem where we come from, and it can also help in the following aspects:
First, in the prevention and treatment of some genetic diseases, new therapies can be adopted, especially some stubborn familial diseases, such as mental illness of unknown causes. On the basis of not violating ethics, tube therapy may achieve good results. At the same time, studying the descendants of some close relatives can study some variables of human genes and improve our genes through scientific methods.
Secondly, through experiments on animals and plants, we can change our living environment, improve our control over nature, change our material life and maintain our dominant position on this earth.
Third, study the past and focus on the future. If we don't change, we can't survive. I believe this theoretical achievement can also help us tide over the difficulties. I will explain the future assumptions in detail in my next paper, Infinite-Infinite.
