The farther apart a man and woman are from each other, the smarter their children will be.

I have heard a saying before, that is: the farther apart a man and a woman are, the smarter their children will be. Is this statement reliable? If it is true, what is the reason? As far back as the 15th and 16th centuries, the Qing Dynasty immigrated a group of people from Gansu and other places to the Daban City area in Xinjiang, and they intermarried with the local residents. This kind of long-distance marriage created a beautiful "Dasaka City Girl".

This not only inspired Wang Luobin, the music master of that year, to compose the beautiful folk song "The Girl of Daban City", but also with the spread of this song, the Uyghur girl of Daban City became famous. Chinese and foreign. Many Chinese and foreign tourists want to catch a glimpse of the girls from Daban City when they come to the northwest. However, nowadays, girls in Tasaka Castle are generally not beautiful anymore. Why is this? After investigation, sociologists and medical scientists found that it turns out that due to traffic congestion in Daban City, locals intermarry in a narrow circle, which has caused the girls in Daban City to generally lose their former charming style!

Because this kind of geographical intermarriage circle is too small, it is often easily ignored by people. In impoverished mountainous areas, farmers can only thrive on a small piece of land for generations, so in the closed mountain valleys, life events such as weddings and funerals are repeated generation after generation. According to a sample survey of 1,441 farmer households in 6 provinces and cities across the country by relevant departments, the intermarriage range of most farmers in China does not exceed 25 kilometers. 84.7% of farmers intermarry and do not leave the county, 51% of the farmers intermarry and do not leave the countryside, and 30% of the farmers intermarry. Intermarrying does not leave the village. There are even many idiot villages where the quality of the population is generally low.

According to reports, among the 431 village committees in Benxi City, Liaoning Province, there are as many as 2,014 people aged 18-45 years old with dementia. Sadly, 697 of them are married.* ** gave birth to 988 children, which adds up to 1,685 fools and idiots. This is the cruel number shown to mankind by the small scope of the intermarriage circle. Men and women whose intermarriage circles are too small may not be relatives within three generations, but they may be relatives within four, five or six generations. They still carry a certain proportion of the same genes. Although some are not related by blood, they will intermarry with each other from generation to generation, and their offspring will carry more and more of the same genes. This is scientifically called "homozygosity of genetic factors."
