Although we humans have existed in this world for millions of years, it has not been long to truly ascend to the "top" of the earth's biosphere, only a few thousand years. However, these thousands of years are very important for human beings themselves, because the knowledge we have accumulated so far and the history we have exist on this basis.
Compared with other creatures on Earth, human beings have evolved rapidly both physiologically and socially, largely because human brains are large enough to use their intelligence to solve various problems. As a simple example, many mammals are born quickly and independently, but it takes at least a few years for humans to do so, in part because our brains need to develop a second time after birth.
However, let us not underestimate the survival wisdom of other animals on the planet. After discovering the "strength" of humans, many animals choose to "hold their thighs" and form a symbiotic relationship with us. For example, from ancient times to the present, various domestic animals that have played a key role in human life, especially dogs, cats, etc., can be described as mutual benefit and win-win results with humans.
Even in today's rapid development of human technology, we still need these animals to accompany us and help us, and they are already one of the closest partners of human beings. However, there are many animals in the world that depend on human survival, such as cockroaches, rats, etc., which are animals that we are not "welcome" but have always existed.
<h1 class= "pgc-h-arrow-right" > the relationship between mice and humans</h1>
Rodents and humans have lived together for more than a million years, and there are numerous accounts of rats in human history. For us, the habit of rats stealing food will undoubtedly bring great harm to human society.
Although humans use methods such as rat poison and cat breeding to eliminate rat infestations, this small mammal with strong reproductive ability, flexible body and tenacious vitality has always existed in our society. After the development of human science and technology, we have gradually begun to discover the role of this small animal for humans.
The study found that the genes of mice, also as mammals, have similarities with humans, and ninety-nine percent of the genes present in humans are found in mice. In addition, the mouse body shape and reproductive ability are easy to control, so it has become a special animal test object for the laboratory.
Many of the drugs we eat today, the modern medical means that can be carried out, are first subjected to animal experiments such as mice before they can continue to develop. From this point of view, the mouse also has an indelible contribution to the development of mankind, we can not just look at it as a harmful animal, its existence has great significance for humans.
< h1 class="pgc-h-arrow-right" > rats are also evolving? </h1>
When we observe the process of human development, we tend to start only from the aspect of science and technology, because it develops very rapidly and has a great impact on our way of life. But according to the research of biologists and medical scientists, in fact, the human body is also evolving, becoming more adaptable to our contemporary life.
For example, researchers have found through dissection that more and more people have begun to have new blood vessels in their hands, and compared with humans a hundred years ago, the proportion of modern people with this blood vessel is much higher. Since humans are constantly evolving, have the animals we live with continued to evolve?
The answer is yes. In addition to those animals that have been genetically selected artificially, such as various domestic animals, pets, etc., rats are an excellent reference for comparison, because we have hardly ever carried out any selection of wild mice, and their changes are completely the result of adapting to the environment.
As a result, some researchers randomly captured some house mice living in cities and house mice living in the rural wild, and made a comprehensive comparison between the two groups. In terms of physical fitness, there is basically no difference between these two types of house rats, so in terms of the key factor affecting our human development, that is, intelligence, is there any difference between urban rats and rural rats?
The researchers made a simple device that contains some food in a house made of plastic blocks, and if you want to enter the house, you need to "crack" some simple mechanisms. To prevent rats from using rodent instincts to crack it, the researchers deliberately chose materials that are less likely to be bitten.
After the experiment began, almost all urban house mice were able to successfully open the "mechanism", but the success rate of rural house mice was only half. After repeated experiments and the change of specific subjects, this result remained unchanged, which means that rats in cities do have more intelligence than mice in villages.
< h1 class= "pgc-h-arrow-right" >why are mice getting higher and higher in IQ? </h1>
So what is it that makes two populations of organisms that are almost identical except for different living environments so different? After research, scientists believe that this change is likely to be brought about by humans. With the development of human society, we live in a city composed almost entirely of man-made objects, and if an animal has only the experience of living in a purely natural environment, then it is obviously unable to adapt to urban life.
So in order to continue to get food from humans, rats in the city also began to "learn" everything in the city, including overcoming some simple obstacles and mechanisms. Compared with urban mice, rural rats are in a more "natural" environment, so their "IQ" will be lower.
That is to say, when humans themselves develop, they actually affect the animals around them, and the IQ of mice has evolved in the years of living with humans. After learning this news, some people could not help but worry: if the intelligence of mice continues to develop in this way, will it eventually evolve intelligent creatures like humans, and even build their own civilization?
Indeed, there are many science fiction literary and artistic works that describe similar plots, such as an earth creature that evolved after various coincidences, and eventually challenged human civilization, and even eventually destroyed human civilization.
< h1 class="pgc-h-arrow-right" will rats evolve into "super rat people", >? </h1>
We know that before mammals "occupied" the earth, dinosaurs were the absolute hegemons of the world, they existed for more than 100 million years, and there were many varieties such as herbivorous and carnivorous, and some also had the ability to fly. It's just that tens of millions of years ago, the fall of an asteroid completely wiped out this creature.
So some people speculate, if it were not for the accident of an asteroid hitting the earth at that time, would dinosaurs have evolved strong intelligence and become "dinosaur people", and there would be no human beings? The same conjecture has also appeared in today's rats, will rats that have become more and more intelligent become "super rat people"?
Although rats are genetically similar to humans, this does not mean that rats can really become a new intelligent species. Humans did evolve step by step, but humans also have some innate advantages, such as upright walking and the characteristics of large brain capacity. Walking upright frees our hands and allows us to use our hands to make and use tools; the larger brain capacity raises the upper limit of our intellectual development, allowing us to continue to evolve over millions of years.
Obviously, as an animal that can neither walk upright nor have a large brain capacity, rats cannot undergo such an evolution, and naturally will not become "super rat people".
<h1 class="pgc-h-arrow-right" > humans and nature</h1>
At least for humans now, the urban house mouse becoming more and more "smart" will only bring us more trouble. For example, the rat traps we set up in our homes will be cracked, and the passages and crevices that would not normally be found by rats will also be discovered. In fact, it is easy to understand, this is also the "countermeasure" formed by rats in order to continue to obtain food from humans.
At least for a short time, it seems that rats will continue to live with us and become a ubiquitous "little ghost". Although rats do contribute to us on a macro level, urban rats not only steal food but also spread the virus, so we should also pay attention to prevention.
It is difficult for humans to completely eliminate a companion creature from our lives, whether it is a mouse, or a fly, a cockroach, or a mosquito.
However, now human beings have gradually understood one thing, that is, we humans are also part of this nature, and we cannot completely eliminate a creature for our own benefit alone, which is likely to cause an irreparable "chain reaction". Because for nature, every living thing has its own meaning and unique role, and some of these functions may not be discovered until it does not exist, and then it is too late to regret it.
< h1 class="pgc-h-arrow-right" > concluding remarks</h1>
Living in harmony with nature is what everyone should do, we are just a species on the earth that has created civilization, not the rulers and masters of the earth, and human beings have an equal status with other living things in essence. Therefore, in the face of changes in the earth's natural environment, human beings cannot completely resist it.
For example, if an asteroid the size of the dinosaurs hits the earth again, humans with science and technology will also be destroyed. We can't resist even the natural disasters that often occur on Earth, let alone the upheavals that can change the history of life on Earth.
For future human beings, how to maintain the common development of nature is the most important thing, we have a powerful science and technology, this technology should not only benefit mankind in the present, but should only contribute to the future of mankind, so that our race can continue forever, rather than self-destruction.
Now, the "double-edged sword" of science and technology has been held in the hands of human beings, and if we do not pay attention in the future, we will really destroy ourselves, and it is not impossible for other animals to "evolve" into the next batch of intelligent creatures. Therefore, each of us must remain fully vigilant about this, starting from ourselves to defend our only home.
