"If it is irreversible and the modified parts cannot be restored to the normal tissue structure of the human body, then are they still considered human beings?"

"In addition, will this kind of modification be deeply embedded in the genes and passed on to the next generation?"

Hearing this question, Xu Chuan also fell into deep thought.

The biological definition of human is mainly based on the research results of multiple disciplines such as biology, genetics and evolution.

From the perspective of philosophy, sociology, psychology and other fields, as long as the four astronauts still think that they are human beings, then they belong to human beings.

But what about basic sciences such as biology and genetics?

Humans are creatures that belong to the kingdom Animalia, phylum Chordata, class Mammalia, order Primates, family Hominidae, and genus Homo.

If we are a little more strict, it is a species of the genus Homo, a primate order with 23 pairs of chromosomes.

Although there are yellow, white, black and other races in the world today, from a genetic point of view, there is not much difference between people with different skin colors.

But can organisms that have been infected by Martian microorganisms and transformed by symbiosis still be classified into this concept?

I have to say that this is indeed a headache.

After thinking for a while, Xu Chuan came back to his senses and said: "Let the higher-ups consider this issue. What we want to solve is not this, but to do our best to cure them."

After a slight pause, he flipped through the physical examination data of the four astronauts transmitted back by the Hanhai space shuttle, and then said: "Those foreign medical experts are not necessarily reliable, and in the end we will most likely have to rely on ourselves for this matter.

"

"Judging from the physical examination data of the four astronauts, Zhai Zhigang and Tang Hongbo's bodies have not yet shown any mutations after being infected by Mars."

"Perhaps we can study their physical condition first to see if they have corresponding biological antibodies or immune behaviors?"
