If there is a crisis in the world, can humanity evolve again?

You can first understand the noun concept of "evolution" (encyclopedia): that is, "in the process of reproduction, the genetic material is recombined and mutated, so that the parents and offspring and between different individuals of the offspring are mutated is called evolution, according to Darwin's concept, evolution is "the passage of ornamental changes". ”

It is easy for us to understand that evolution is an evolutionary process in which species adapt to environmental changes and survive, for example, why are people in the north taller, the cold in the north, the harsh living environment, and the need for physical struggle, etc., which gradually lead to the selective inheritance of gene groups, because the relative survival probability of the weak is low, so it is slowly eliminated, but with the progress of society and science and technology, people can change many natural factors the day after tomorrow, which is why the average height of people is generally up now.

In fact, evolution is a long (relative to a person's life time is only ten years) and redundant process, if there is a momentary crisis in the world, then it may be a one-time irreversible cause of great damage, human beings can not talk about adapting to evolution has been extinct, of course, it is not excluded that some people who have adapted to the high-risk environment may survive and reproduce, and it also depends on whether the innate genes of human beings can survive, such as "oxygen" is gone, At present, even a master of breathlessness can hold his breath for about 30 minutes, and he should not be able to live.

To sum up, if there is a crisis in the world, we need to see what kind of crisis it is, as long as human beings can barely survive, even if the conditions are bad, there will be a certain amount of survival, and continue to evolve to adapt, because if you don't evolve, you will perish, and this is not something that human beings can choose by themselves.

Do you also want to fight hordes of zombies? You're also struggling to find lonely humans scattered and hiding everywhere, **me, before they are taken over by zombies.

Of course, human beings can still evolve, human beings have never stopped evolving, and the evolutionary history of human beings for millions of years has only taken on its current appearance, and now human beings have not completely separated from the natural environment, and they are still selected by the environment.

The improvement of human medical care and other fields, to a certain extent, makes people go in the direction of detachment from nature, but it is still far away, environmental factors still continue to affect the human body, biological, chemical, physical factors can also make the human body gene mutation, it can be said that as long as breathing air, as long as eating, as long as basking in the sun, it will be harmed by some undesirable factors, genes may change, and it may be transmitted to offspring through reproduction, so that the gene frequency in the offspring population changes. The process of survival and reproduction is also accompanied by genetic mutations, which is why the offspring are always a little bit less like the parents, the genes inherited from the parents make the parents and the offspring have some commonality, and the mutation makes the offspring have some personality.

Over the past few decades, human living habits have undergone a lot of changes, various factors have led to the continuous change of human gene frequency, some scientists have extracted the genes of 200,000 people and their offspring, and after monitoring the gene sequence, it was found that the gene frequency of the offspring in terms of alcohol tolerance has changed significantly. Changes in gene frequencies are evolutionary for populations. There is also an increase in the obesity rate of modern people, and obesity is also related to heredity, and it is also a change in the frequency of related genes.

Although the changes that have taken place in modern humans are not obvious to the naked eye, human genetic technology has been able to understand human evolution at a more essential level.

Human beings will continue to evolve and adapt to the environment, until human beings need to actively change their genes to adapt to a more complex cosmic environment, and then there will be more "new new humans" who adapt to different starry skies. Everything is always in constant motion and change, and so is human beings, constantly developing and progressing, that is, evolving to a higher level. It is not difficult to see that the human brain has evolved to the Internet age and the flying age, which is where the process of human evolution lies.

The human brain has unlimited imagination and creativity.

Yes. Because the evolution of living things is controlled by the environment, and the environment is always changing, human beings can continue to evolve.

I think that of course human beings can continue to evolve, because the times are evolving, and human beings definitely need to continue to evolve in order to adapt to the global environment.

Personally, I think that human beings can continue to evolve, because we humans are constantly changing, but the evolution is relatively slow, and it is difficult to see.

Don't worry, you'll soon evolve into a high-level monkey again, or a rabbit or a haunt.

Humans evolve naturally. Humans must still evolve, otherwise they will slowly become extinct. In fact, the reason is very simple, that is, the human body alone cannot resist the changes in the external environment. In the Paleocene Eocene.

At that time, the earth's temperature became very high, and even the polar regions were covered with lush forests, and with our current bodies, it was difficult to live in a hot environment.

under life. It can be seen that the earth's environment is not prepared for human beings, but will undergo various changes, but human beings just adapted to the environment when they evolved, so they appeared on the earth. But we are only adapting to the current living environment, and if the earth's environment changes dramatically again, human beings may not be able to continue to live on the earth.

According to scientific theory, life on earth is in the process of evolution all the time, and man, as a higher animal, is no exception.

You can't see it, but you can see it. For example, the cecum of a person is constantly degrading because it is not used. So, maybe in many years there will be no cecum.

For example, the vitality of the Y chromosome is gradually declining, so some people say that in the future--- of course you will not see it--- there will be no men, depressing!

Constant evolution is the only way to satisfy the choices of nature, that is, the universe. In the face of the universe, man can only evolve.

But it's been a slow evolution, and you can't see it

Yes. You think.

In ancient times, humans were a branch of primates.

It took millions of years of evolution to become what it is today.

It is said that the sixth mass extinction that will shock the world will be .........Humanity itself.
