Review
From its birth to the present, the earth has produced a variety of creatures, and we have to lament the mysteries of nature's creation, but also often have doubts about our human life. Compared with other creatures, the most significant feature of human beings is that they have higher intelligence.
However, many people will ask: the earth has been billions of years old, and the natural world has given birth to countless kinds of creatures, why only we humans have such a high IQ? There is a view that the emergence of human beings may not be accidental, and there should be some factor that leads to the emergence of us humans.
Humans may have been created
There are some views that humans living in three-dimensional space may have been created by some kind of higher civilization, which may be in a high-dimensional space or in a state that human beings cannot understand, and this view is reflected in many movies.
If these and those higher civilizations lived in the same dimension, there would be such a possibility: they used advanced civilization technology to dominate the earth earlier, and at that time we humans were still in the lower biological stage, these civilizations may want to figure out what stage those lower organisms can evolve to, their ability can already genetically modify organisms, so the emergence of human beings is the result of their genetic modification of the lower organisms at that time.
If we lived in different dimensions from higher civilizations, and thought about it, the world we live in now might not be entirely real. In the words of Albert Einstein, high-latitude civilizations can create low-latitude civilizations, that is, the real world we think of as a game world or a fictional world for high-dimensional civilizations.
Even if, in some ways, the conjectures of these views are not unreasonable, but whether human evolution to the present day is related to a higher civilization, the scientific community does not have a definite evidence, and the existence of an advanced civilization itself is an unsolved mystery. But as scientists learned more about different creatures, they began to see shadows of human evolution in some animals.
The IQ of mice
Not only human beings, the evolution of any kind of organism to this day is not accidental, it takes a long time and certain external conditions to evolve, but human beings are affecting the evolution of some organisms.
Not long ago, a German scientist did an interesting experiment to figure out how rats living in different environments would react with their own intelligence, and finally he set the difference between the environment in the city and the countryside.
The scientists used 31 mice as test subjects, of which 14 were placed in the city and 17 in the countryside, where rats often interacted with humans, while the mice in the countryside lived in sparsely populated areas.
Then the scientists put together a house out of building blocks, put food in the center of the house, and they put rats that lived in the city and the countryside for a period of time outside this building block house, and the other conditions were the same, only the environment in which they lived was different.
It turned out that rats living in cities were more likely to find food than rats living in rural areas. The experiment showed that rats living in cities had to learn to deal with humans in order to survive, so they had to make themselves more intelligent to survive.
In order to ensure that the results were accurate, they chose different environments to do the experiment, and the results were the same, and the mice living in the complex environment had higher IQs. This experiment shows that the influence of the external environment on biological evolution is still very large.
Will there be a "rat man"
Scientists have studied that the genetic similarity between mice and humans has reached a terrible 85% to 90%, which is why many scientists choose mice when doing experiments. Some people say that if you give rats a creature a long enough time to evolve, they may become as intelligent as humans, and even evolve into "rat people".
Some scientists have made such a hypothesis, if future technology can put mice on a planet in outer space to live, just wait for more than ten years or even hundreds of thousands of years.
Given that the rat lived in such a suitable environment, and without the interference of natural enemies, could it evolve to resemble a higher organism like humans?
Obviously, this hypothesis is impossible to achieve, rats are mammals like humans, if you put rats in outer space, then the planet must have the same environmental conditions as the earth, which is very difficult to do, and if you find such a planet, then why don't humans open up a new home.
Secondly, there is a certain scientific basis for the similarity of rat genes to humans, and the fact is very simple, because rats are mammals like humans, and all mammals have the same ancestors hundreds of millions of years ago, so it is not so strange that the genomes of mice and humans are similar.
In fact, rats have become more intelligent than before, more caused by human influence, and humans will not allow any creature to become as intelligent as humans, because it will threaten the survival of human beings.
brief summary
At present, there are many people who are worried that in the future, rats will evolve to replace human supremacy on the earth, and science says that this worry is very worrying, but it does not rule out the possibility that, like in the movie, there are some crazy scientists who use genetic technology to modify the genes of mice, promote the evolution of mice, or fuse the genes of humans and mice, so that "rat people" become a possibility, so that rats become highly intelligent creatures like humans, which is also possible.
