Transform into a fairy girl

Years pass by, time flies.

The happier the time, the faster it disappears.

In the blink of an eye, ten years have passed.

Emma Linke has become a thoroughly middle-aged man and has begun to enter the stage of old age.

The three children have all grown up. Although they are all sensible, there is a big problem in front of Ji Ran, which troubles her very much.

It's time for male seniors to get married and female seniors to get married. However, apart from their family, there are no outsiders here.

Franks and Cao Kesi are brothers and have always had a good relationship, but recently they have become jealous of each other because of Elena.

Obviously, both brothers like Elena very much, and Elena is indeed a good girl, she looks like Ji Ran, and is even much prettier than Elena.

She is ingenious and has learned all Ji Ran's skills. She is a beautiful girl that everyone loves.

Franks and Cao Kesi both like Elena and feel that they are more suitable for her.

However, they don't know that none of them is actually the most suitable ideal partner for Elena, because they are biological brothers and sisters.

Biological brothers and sisters in a family are not allowed to be together.

Although in this deserted hot spring valley, the laws in the normal human world do not apply, and no one can really punish them, Ji Ran still does not want to break such human rules.

After all, they are family.

Emma Linke is completely opposite to Ji Ran's opinion. He believes that the conditions here are limited and their children should not be restricted by the laws and regulations in the normal human world.

If Franks and Cao Kesi don't marry with Salina, then their family's bloodline will be interrupted. In a few decades, this place will become a desert with no one. This is something Emma Linke absolutely cannot accept. of.

Emma Linke not only agrees with Franks and Cao Kesi’s ideas, but even thinks that Elena, as her daughter, should contribute to her family. She must not only communicate well with Franks and Cao Kesi, but also try her best to To create more blood and life for the family, so that the family can be more prosperous and this beautiful valley can become a true paradise and paradise.

In order to persuade Ji Ran, Emma Linke also deliberately brought out some special dynasties in history. Some dynasties were intermarriages between royal families. Most of them were brothers marrying sisters, or sisters marrying their own brothers. In this way , the blood of future generations will be considered more pure.

Those dynasties actually existed for a short period of time, and some even lasted for hundreds of years.

In other words, although incest marriage has various genetic defects, it is not absolutely sensational. As long as the number of offspring is sufficient, cross-breeding on a larger scale can actually be eliminated through natural selection. To get rid of some members of the tribe who have genetic defects, and finally leave a group of offspring that are as healthy as normal people.

In fact, in the distant ancient times, human beings were the offspring of a group of homo sapiens living together with a small population after intermarriage with each other.

This is not difficult to understand, because humans are all offspring of parents, and parents

They come from grandparents and maternal grandparents, and further back, grandparents and maternal grandparents come from great-grandparents and maternal-great-grandparents and maternal-great-grandparents. In other words, our existence is in the generation of our parents. A person needs two people, a father and a mother. When it comes to the grandparents' generation, four people are needed, the grandparents and the maternal grandparents. If you push forward, you need eight people, sixteen people, and thirty-two people.

By analogy, if we push forward 33 generations, we will have more than 80 billion ancestors, which is almost the same as the population of the world today.

However, 33 generations ago, it is estimated that it was only about 1000 years ago, that is, around the Northern Song Dynasty. At that time, let alone the Northern Song Dynasty, there were probably not hundreds of millions of people in the world.

At that time, when the great integration of nationalities had not yet fully begun, assuming that our ancestors were all pure Chinese, then, based on the population of 2000 million at the peak of the Northern Song Dynasty, during the Northern Song Dynasty, on average, each person appeared The number of times in our family tree is at least seventy times.

Of course, this does not include the situation where some of them have no descendants, or their descendants later have no descendants. If these situations are also removed, then in 1018 AD, on average, each person from the Song Dynasty appeared in our family tree. The number of times has reached more than a hundred times.

What does it mean

That is to say, it is very likely that the son of your No.30 third-generation ancestor is your 32nd-generation great-grandfather, and may be your No.30 second-generation great-grandfather, and may also be your No.30-[-]st generation great-grandfather, because he Among the descendants, there may be a branch that reproduces quickly, and a generation may be lost within a few generations.

In other words, no matter how distant your blood relationship is, your generation marries a wife who seems to have no blood relationship, but the blood in your body has actually been changed countless times in history. Repeated.

If you could go back 3000 years ago, all the people in the world at that time were your ancestors and your relatives. If you compared the blood relatives with them, they were all your relatives. You said it was magical. Not magical

If we push back even further, we can even find a common ancestor, and his name will appear in the genealogy of all humans. In other words, we are actually descended from the same ancestor.

Everyone knows that the earlier the time, the smaller the number of ethnic groups, because it is caused by extremely harsh natural conditions. Therefore, even a very small family can reproduce if it reproduces in large numbers. developed into a large population.

Humanity has developed step by step through this process of constant repetition of blood lines.

The reason why there are big differences among many races now is probably because they have differences in adaptability in different environments.

Emma Linke wanted to explain this truth to Ji Ran, but due to his limited expression ability, Ji Ran was confused and confused. However, after calming down, it was not difficult for Ji Ran to understand. The truth that Emma Linco wanted to express.

Although in terms of racial reproduction, inbreeding is an inevitable choice when necessary, there is still a big hurdle in Ji Ran's heart that is difficult to overcome.

For the sake of race, they trample on the rules of civilization accumulated by mankind for thousands of years.

Or should you allow your own race to become extinct in order to abide by the rules of human civilization?
