Chapter 428 428. Interstellar Fertility Rate

The fertility rate of any species in the interstellar world is very low, except for the tenacious Zerg that "cannot be burned away by wildfire, but reborn again when the spring breeze blows", like a weakling that cannot be killed.

They reproduce very quickly, and under suitable environmental conditions, the population can even grow in a "blowout" style.

Not only do interstellar people have a low fertility rate, but the survival rate of their cubs is also low. Even if interstellar medical technology is advanced, diseases closely related to "genes" are still a subject that still has a long way to go.

I don’t know if it is related to various known and unknown radiations that exist in the universe, or maybe it is due to changes in eating habits and other living habits. Over the long years, the appearance characteristics of interstellar people in some galaxies have mutated. Mars is During the interstellar "campaign", I saw all kinds of interstellar people in different forms.

Most still retain the basic "human" shape, with a head, torso and limbs. The appearance has undergone major changes, mainly facial features, skin and height.

At this time, Mars was pointing to a picture of an alien that looked like a "dwarf" in his optical brain folder, and introduced it to the aerospace trainers who gathered around him enthusiastically to "listen" to the lecture.

"...This is the Golden Star of the M89 galaxy. The Golden Star is rich in gold, hence the name. Each of these little dwarfs is a natural gold digger, and they are also one of the 'loved pets' of the interstellar nobles."

In the picture, a group of "dwarfs" about thirty to forty centimeters in height are looking blankly at the camera. Compared with their "immature" bodies, their overly large heads make them top-heavy, and they look like malnourished big heads. baby.

Everyone who saw the picture felt sad.

"This picture is of the official conservation center on Blue Earth Planet. Here, the germ cells provided by both men and women are fused and fertilized through an 'incubator', and are further cultivated and developed into embryos until they mature..."

"Why do you do this? Is it because in interstellar life, women's bodies have been damaged and cannot bear the function of pregnancy?"

Someone from the United Nations raised his hand to ask a question.

"Well, it's not just that. The interstellar environment is complex, and there are many unknown substances that we don't understand yet that are quietly changing our physical fitness. Regardless of men and women, if you want to naturally give birth to a healthy offspring, you need to put in a lot of energy. And hard work... And after finally giving birth to a new life, it may die due to various diseases. Over time, the interstellar people want to collectively destroy it. Later, the official realized that something was wrong, intervened in time, and established a 'nursing center'. Restored a little bit of interstellar fertility that was already in jeopardy."

Precisely because he had seen the difficulty of giving birth to offspring in the interstellar world, Mars was full of curiosity about the bustling and huge human population on the earth, as well as the animals and plants that can be seen everywhere.

I am especially interested in those lively “big families” on earth where several generations live together as a family unit.

He had never experienced the feeling of "home" before, and it felt very fresh just thinking about it.

In the interstellar world, people rarely have "brothers and sisters", they are rare and special existences.

And he has a mother, but he is like an "orphan".

But on earth, Mars realized that he had many brothers, as well as many sisters.

He has regarded himself as a member of the earth. Blue Earth Star, to him now, is just an emotionally indifferent and alienated "manufacturer".
