Chapter 837 Replacement

"Senior...can I ask a few questions?" The original source looked very curious about the story just now.

"Don't be so formal. If you have any questions, just ask." Xiang Shan said: "Our journey is quite long anyway, so it's good to chat."

This is really a sad fact. Although humans can already fly at a few percent of the speed of light in space, there is no significant breakthrough in speed under the water. At least it's difficult to move quietly.

If driven by a nuclear reactor, the submarine can indeed get up quickly, but then there is no point in diving underwater specifically.

In this era, if you make too much noise, it will be easily detected.

Because now, there are few animals in the entire sea.

Many years ago, Yawgmoth made a last-ditch effort to save some marine life. If those creatures are still there now, they should probably be limited to the vicinity of the equator.

There are still many microorganisms in seawater. When Xiangshan was on the shore, he also took samples from the shallow sea and observed them. Some of them look original and natural, while others have heavy artificial traces. Perhaps this is the result of the labor of the Scientific Research Knights.

Moreover, the Scientific Research Knights, who study planetary physics, will still put monitoring facilities into the sea. If the monitoring equipment's readings are too abnormal, it may attract unnecessary attention.

Although the satellite network is now down, and most monitoring facilities cannot be connected to the Internet, the government can still have an alarm system that relies on ground waves to complete communications.

In order to ensure privacy, Xiangshan could only choose to walk slowly.

Yuan Wenren nodded and said: "Senior, I just think it's strange. According to your story, there should be Homo sapiens existing at that time..."

"Yeah. A few." Xiang Shan nodded, "That's true."

"According to this logic, shouldn't they be relatively trustworthy people?" the original source asked: "There are no backdoors implanted in their genes, nor can prosthetics be implanted, and they will not be controlled... …”

"Well, this is a good starting point." Xiang Shan nodded: "But you have to consider one thing. The average age of the last batch of Homo sapiens is eighty years old. You know what eighty years old means for Homo sapiens What are you wearing?"

"dying?"

"It's aging." Xiang Shan shook his head: "You really haven't thought about this problem at all... But at your age, you don't need to think about such things. It's really strange. The aging of baseline people should actually be longer. right……"

Baseline Man is an artificially created species, and it is only a "springboard" for the next step of transformation in an industrial environment. In a purely natural state, this species has quite a few uncoordinated traits.

For example, aging.

Baseline humans do have a natural lifespan of about four hundred years, but relatively speaking, they have inherited the genes that control the life cycle of Homo sapiens.

A gene can determine or influence the formation of multiple traits. There is a theory that the same gene will show different traits at different ages - this is the secret of aging. In infancy, genes for bone calcification play an important role in growth, but after childbearing age, these genes increase the risk of coronary artery disease and myocardial infarction. Likewise, in early life in humans, the sex androgens - androgens - cause the development of glands. But the same hormone increases the risk of prostate cancer after childbearing years and increases mortality in human males.

From an evolutionary perspective, this may be to allow individuals who have completed their vocation to pass on genes to die quickly to free up resources for the next generation, and also to quickly eliminate individuals who fail to pass on genes.

Yawgmoth implanted foreign genes into human genes and reset the enzyme system. Cells will synthesize enzymes that they could not synthesize before, opening up more new reaction pathways. However, most of the genetic data of the baseline human is still inherited from Homo sapiens.

Genes that regulate aging are also included.

According to the papers related to the Scientific Research Knights that Xiangshan has downloaded in the past few years, baseline people will start to show an aging trend around the age of eighty. If no technical means are involved, this trend will continue for one or two hundred years. The basic human's damage resistance will greatly prolong this process.

In fact, Xiangshan didn't care much about this issue at first. In his view, the benchmark man exists as a springboard and platform for "prosthetic transformation". Whether it is "cardiovascular disease" or "cancer whose incidence increases with age," it is not a problem for the baseline person who has become a prosthetic.

The nerve cells of the brain are the slowest aging part of the human body. Even in a natural state, without the intervention of any drugs or gene therapy, baseline people will experience deterioration in thinking ability between the ages of 180 and 200. If similar drugs were available, this process could be extended indefinitely.

Nerve cells themselves are also cells that do not die easily.

The nervous system is very simple at the cellular level. Reversing its life cycle is a project that Yawgmoth completed in the 21st century.

In other words, so far, human civilization has not observed a benchmark human who truly died at the end of his life span.

For knowledgeable people, it is not difficult to obtain enzymes. In the discourse of Jianghu children, "old knight" represents "powerful" and "high moral prestige", and there is no such thing as "boxing is afraid of young people".

The concept of "aging" seems to have been thrown into a small corner that is not taken seriously by human civilization.

If Xiangshan had not witnessed an old man who lost his ability to act due to aging a few years ago, he would probably have forgotten this concept.

"Eighty-year-old Homo sapiens, no matter how healthy they are, their physical strength and energy are not as good as before. At that time, human thinking will still be affected by heartbeat, breathing and hormones. The aging body can hardly support the ambition." Xiangshan said: "They began to gradually withdraw from the center of power in the late 1950s."

Yuan Wenren didn't understand this point: "From the protectors I have seen... they should try to grasp the thing called 'power' until the last moment, and never let go until they die, right?"

"This matter is beyond their control." Xiangshan sighed, "When the tide of human cyborgization was unstoppable, the old people jointly issued a ban, prohibiting the standard people from becoming the leaders of the country before 2055. But in the late 1950s, the total number of standard people had exceeded that of Homo sapiens. The standard people felt that the standard people could better reflect the voice of this group. The young and vigorous people also seized power in the voice of the masses."

Of course, all these young and vigorous politicians have prosthetics, and many of them are sponsored by Superman Enterprise.

In addition, since they valued their lives, none of them chose to undergo the first few surgeries. They wanted to wait until others had their surgeries done before seeing the results.
