/kloc-what will human beings look like in 0/10,000 years? Scientists have drawn a sketch, and humans may no longer be afraid of death.

In the 4.6 billion years of life evolution of the earth, human beings should be regarded as a kind of life with relatively fast evolution process and more evolution dimensions. Just like the dinosaur overlord who once dominated the earth for 65.438+69 billion years, after so many years of evolution, there is almost no big difference between extinction and when it first appeared. However, human beings were born from primates. According to the theory of Australopithecus in mainstream academic circles, it only takes 2-3 million years to evolve from Australopithecus to humans.

In these millions of years, human habitat has shifted from trees to land, and the way of walking has changed from landing on all fours to walking upright on both feet. It also quickly entered the primitive society, experienced agricultural and industrial civilization and entered the modern society. Moreover, human beings are the only creatures on earth that have evolved civilization.

In just a few million years of evolution, human beings have stepped onto the top of the earth's food chain. Therefore, human beings can't help wondering, in the next 1 100 million years, will human beings evolve as rapidly as they do now, and what will human beings become at that time?

Human science and technology complex

Will our descendants become electronic people with high-tech machine implants, renewable limbs and cameras, as in science fiction? Will humans become a hybrid of creatures and humans? Or will we become smaller or taller, thinner or fatter, or even have different facial features and skin colors?

Let's demonstrate one by one. At present, the population of the earth has reached nearly 8 billion, and the modern lifestyle has caused mankind to consume a lot of earth resources. So according to the current situation, scientists estimate that the earth can only support the lives of 20 billion people at most. Natural selection, survival of the fittest, under this evolutionary law, is it possible for human beings to evolve to a smaller size? Because of this, our bodies need to consume less energy and give the earth more breathing space.

At present, if an organ is damaged, we can treat it through organ transplantation, such as liver transplantation. This kind of treatment is still a substitute function of human body function. With the development of AI technology, we can use more other materials to solve these functional problems, and even enhance this functionality to some extent, so as to realize the integration of human body and mechanical body. For example, we can transform the appearance of the body, implant powerful artificial eyeballs for some blind patients, let them see everything in the world like normal people, and also realize infrared or dynamic snapshot.

Moreover, we can also upgrade the prosthetic limbs of the disabled, adding functions like mechanical arms or leg supports in movies, so that they may be more flexible than normal people.

Conscious society

Previously, Facebook officially changed its name to Metauniverse, which ignited the heat of this topic. Metauniverse is just a social lifestyle composed of everyone's ideology. Through the brain-computer interface, we preserved the human brain consciousness and transmitted it to the meta-universe. In this universe, human beings can complete various social activities by manipulating consciousness. If it can be realized, human beings can realize the classification of body and consciousness, which will also realize the goal that human beings want to achieve eternal life.

Such a society can also solve the problem that the earth's resources are about to be exhausted once and for all. Because consciousness is immortal and consumes less energy than the body. However, there is an obvious problem in this universe, that is, human consciousness has always existed, and it will always be the consciousness of this generation, and it is difficult for innovation and new species to appear.

Moreover, where there are people, there are rivers and lakes. Conscious bodies will also be influenced by the law of the jungle in this universe, and some conscious bodies will be destroyed in some way.

Genome editing

Although at present, we often use hybridization or backcross in animal and plant breeding to cultivate more suitable varieties. However, due to the constraints of eugenics and legal ethics, the population in most areas still prohibits close relatives from getting married and having children.

However, some genetic diseases can be avoided by screening genetic materials through scientific means. A few years ago, I also heard that editing human genes artificially manipulated the characteristics of future generations. There is a metaphor called designing babies. However, this is prohibited by law and has caused widespread controversy around the world. Just as cloning is completely resisted, it will bring complicated moral and legal problems.

However, because human genes are constantly adapting to the changing environment, they have evolved accordingly. If the earth's environment changes greatly after 654.38 million years, if the greenhouse effect leads to global warming or melting glaciers, people's bodies will become more slender in order to better dissipate heat. Or like the large-scale cold wave caused by the double La Nina phenomenon in winter, it is possible that the hair of the body will become thicker and resist the cold.

Our life is closely related to the environment, and our descendants will adjust our genes through natural or artificial selection in the process of adapting to the environment.

Spatial migration

Out of concern for the earth's environment, human beings began to look to the vast universe, hoping to find a second home similar to the earth. With the development of space science and technology in various countries, human beings also have the ability to travel in space. At present, China astronauts are testing their living conditions on the space station for six months. Because the environment between space and the earth is very different, short-term space life has made us see some changes in the physical appearance of astronauts, such as obvious swelling of the face. And every time I return to the earth, my leg muscles can't stand fast because of the lack of traction of gravity for a long time. I can only gradually recover to adapt to the gravity of the earth through a period of rehabilitation training.

However, if a large number of human beings immigrate to space in the future and live in zero or low gravity environment for a long time, the human body may also change. In the low gravity environment, the muscle structure of our body will also change. And without the bondage of gravity, our limbs will become longer.

If we can manipulate our genes artificially within certain rules in the future, can we get rid of the influence of natural selection and evolution? For example, now we can kill some diseases in the cradle by screening genetic diseases. In the future, with the development of social civilization, genetic technology will be better used legally, making the human species better.
