Chapter 843 Quantitative Change Leads to Qualitative Change
When the simulation entered this stage, Xu You finally came to an important conclusion.
On the road to the birth of life, many individuals of life just appeared and said goodbye to the planet without even leaving any offspring, bringing this kind of life to a quick end.
It was not until the birth of truly reproductive individuals that the first species appeared on the planet.
"Quantitative change leads to qualitative change. When there are enough chemical substances needed for life on the planet, as long as the environment is right and there is enough time, life forms will definitely be born. It's just that the same experiment cannot be reproduced in the laboratory." Xu You thought.
Because it is definitely impossible to conduct experiments continuously for hundreds of millions of years in the laboratory, such work can only occur in simulations.
Next, Xu You continued to focus his attention on the simulated world of the brain and observed the subsequent evolution of life.
After several generations of evolution, this species continued to grow and expand its territory.
Although their vitality is not very strong and each individual may only survive for a few days or even just a few hours, their overall number continues to expand due to their strong cell division ability.
As they continued to reproduce, their species characteristics also underwent some changes, and they continued to evolve in a direction that was more suitable for survival.
After all, whether an individual life can survive for a long time is entirely a choice made by the environment. Therefore, after a long period of evolution, the species has become more and more adapted to the environment of the planet, and the individual survival time, reproduction rate, etc. have all improved to varying degrees.
Just when Xu You thought that this species was about to develop in a more advanced direction, some new situations emerged.
For some reason, the environment of this planet has changed drastically.
Under this drastic change, the species that had adapted to the planet's environment suddenly became unable to adapt to the new environment and all died.
This kind of death is a real mass extinction, just like putting a bunch of cells in boiling water and boiling them forever, and no cell can survive.
In this way, the planet once again entered an era without life.
After watching the whole process, Xu You couldn't help but sigh.
"Life is so fragile that a species can easily become extinct just by a sharp rise in temperature."
At this moment, Xu You couldn't help but wonder whether a similar situation occurred in the early days of life on Blue Planet.
After hundreds of millions of years of evolution, a life or a species was finally born, but they still became extinct due to force majeure, and the planet once again entered a lifeless period.
Only after a similar development process was repeated many times could species gain a foothold on the blue planet, continue to reproduce and evolve, survive one mass extinction event after another, until the final birth of humans.
After sighing, Xu You readjusted his state and continued the previous simulation.
After the first species became extinct, although the planet no longer had life, it did not completely lose its "vitality."
This so-called "vitality" is because the planet contains various chemical substances .
This is the basis for the formation of life. With these substances, it becomes possible for life to appear on the planet again.
After hundreds of millions of years, the planet successfully gave birth to life again, life with the ability to reproduce!
"It's not the same as the previous generation, but there are some similarities. It seems that the appearance of many things is not accidental."
This time, the species is larger in scale than the last time, and it has existed for a longer time.
However, after a similar harsh environment appeared, the species was once again destroyed by the environment and no individuals survived.
In this way, Xu You kept carrying out the simulation, and dozens of similar species were born on the planet. However, because the environment of the planet was not so ideal, these species eventually failed to evolve into advanced forms and became completely extinct.
"Four billion years have passed... It seems that it is difficult for this planet to give birth to advanced life."
After a series of simulations, Xu You was basically certain that there was a high probability that life had existed on Mars, but these lives were all very simple in form and did not last very long.
Even so, this is a very great discovery and will have a very significant impact on the study of biology.
Coming out of the brain simulation state, Xu You felt mixed emotions.
This discovery is certainly of great significance, but from a certain perspective, it also proves how fragile life is.
Even a planet like Mars, which is more suitable for the emergence of life, ultimately failed to successfully give birth to species that can live on the planet for a long time.
"Teacher, have you finished your simulation?"
Seeing that Xu You's condition had changed, Lin Shi hurriedly asked Xu You.
"Yes, it is basically certain that there was life on Mars. However, this life was very simple, similar to the earliest single-celled organisms on the blue planet."
Xu You was relatively calm when he spoke of this, but Lin Shi seemed very excited when she heard this.
"Is this true? That's a major discovery in the history of human biology!" Lin Shi said excitedly.
"Yes, this is certainly a milestone discovery, and it may even change human civilization. No, I have to plan my next research work carefully."
Xu You knew how significant this discovery was, so he immediately began to think about this problem.
In fact, Xu You has never had a specific plan for how to arrange his time, because things are changing all the time, and Xu You must adjust his time arrangement at any time according to the situation.
Once there is a major breakthrough in biology, humans will likely undergo fundamental changes.
After some thought, Xu You decided that after returning to Blue Star, he would immediately set up a new project team in the biology laboratory of Jijing University to carry out this part of the research work.
Thinking of this, Xu You immediately contacted the relevant personnel to discuss the project establishment.
"Through my simulations, the fact that life existed on Mars has been basically confirmed. Now we need to conduct some research work to further verify some conclusions and complete some exploration work," said Xu You.
