The Earth we live on formed about 4.5 billion years ago in some dust floating in the solar nebula, through the collision and bonding of materials at different times, and finally like a "snowball" to form an early primitive planet.
However, in the early days of the solar system, due to the "initial opening of chaos", the cosmic environment in which the earth is located is still very unstable, including the risk of collision between the orbits of the original planets, and there are asteroids or comets at any time.
For example, NASA scientists have found that the formation of the moon may be caused by the impact of a primordial planet the size of Mars. According to the "Great Impact Theory", at the place where the Earth formed, after a primitive planet named Theia hit the Earth, the magma, gas, chemical elements and other materials that were separated under the action of the huge impact force were recombined to form the Earth's satellite "Moon".
Moreover, the temperature in the early days of the Formation of the Earth was also very high, and under the action of gravitational contraction, radioactive decay and frequent impacts of asteroids, the Earth was in a "molten state" until a stable core, mantle, crustal structure, and hydrosphere and atmosphere were formed.
After the earth's cosmic environment or its own environment tends to be stable, this provides a possibility for the birth of life on earth, such as the early primitive life of the earth was born in the ocean, and then experienced hundreds of millions of years of evolutionary development, gradually evolving from "low-level" to "high-level", and some organisms also migrated from the ocean to the land, about 3 million years ago, highly intelligent human beings began to appear.
Today's earth, living millions of creatures, many of which belong to the "living fossil" of endangered species, and some also because of the strange appearance of human "ugly but cute" praise, like Zhejiang Shaoxing, Hunan Changsha and other zoos a monkey because of the "national character face" and bump face of humans has caused netizens to discuss.
According to the report, when a female tourist was playing at the Shengzhou Zoo in Shaoxing, she accidentally found a monkey with a "Chinese character face", resembling a human face (that is, a "human face monkey"), which immediately attracted the attention of many netizens after the news was issued, and commented that "bumping face cow grandpa".
Once the monkey version of the "national character face" was exposed, many questions also followed, why did the monkey have a "human face"? Is the zoo "acting to attract tourists"? Monkeys and humans "collide", is there a "second civilization" on the earth?
Of course, there are other problems, you can make up for the officials on their own, let's see the specific situation.
According to the head of the zoo, this kind of monkey with a full beard and a "national character face" is indeed a real animal in the zoo, and the number is 5-6, which is an "alien species" introduced from abroad in 2018, and its Chinese name is actually called "black hat hanging monkey", which belongs to an endangered species abroad.
The person in charge also carried out some science popularization on the origin and body characteristics of the black hat hanging monkey. He said that this kind of monkey is raised well in this (Chinese character face) look, and it is becoming more and more obvious, very powerful, very beautiful.
In fact, the black-hated hanging monkey is a gregarious genus of the genus Capuchin in the primate capuchin family, distributed in the humid tropical rainforest of 2700 meters east of the Andes Mountains in South America, mainly feeding on fruits, seeds, insects, etc., that is, it is an omnivore.
The black hat hanging monkey is medium to small, the adult individual weighs about 2.3 to 4.8 kg, the head body length is 35-49 cm, the tail length is 38-49 cm, see no, its tail and the head body length is equal or slightly longer, is the most capable of curling the tail of the hanging monkey family.
However, the biggest "highlight" of the black hat hanging monkey is not the long tail, but the thick black hair on the top of its head that resembles a "hat", which is also the origin of its name "black hat hanging monkey".
Moreover, the fur color of the black hat hanging monkey is also many, from brown, dark yellow to black, that is, the color is very diverse, but its shoulders and lower abdomen are lighter than other parts of the body, so this "shade matching" hair pattern, coupled with the "boxy national character face" is more powerful, so some tourists call it "national character face monkey".
The black hat hanging monkey "collides" with humans, and the Panama monkey exhibits "human behavior", which is a sign that a second civilization may appear on Earth?
Judging from the popular knowledge of the above-mentioned black hat hanging monkey, this "face-shaped" monkey is indeed grown under natural conditions, but not every individual will have such a "national character face".
A deputy squad leader of the Primate Hall of Changsha Ecological Zoo said that large black hat hanging monkeys are often more likely to appear "National Character Face" and have a lot to do with "eating". For example, in the "monkey kingdom" hierarchy is also relatively strict, the monkey king is more likely to eat more well and "fat" to grow a "national character face", which may also be a symbol of "identity".
In the same way, black-hat monkeys with stronger physiques and faster foraging speeds are also prone to this facial shape. Therefore, the black hat hanging monkey "bumping face" humans is purely a "coincidence" in nature, so it is not a sign of the rise of the "second civilization".
The Panamanian monkey shows "human behavior", in fact, mainly about a Panamanian capuchin living in Panama (also called the white-faced capuchin monkey or white-headed capuchin monkey), these monkeys will choose stones, and then choose stone tools differently according to different foods.
For example, they will use larger stones to smash nuts, some will even take the stones to stand up and quickly crouch down to smash nuts, while smaller stones will smash snails, hermit crabs and other small animals, and they will also use branches to drive away dangerous animals such as bees and snakes.
What we need to know is that about 3 million years ago, human beings were only highly intelligent, and the tools commonly used by ancient humans at that time were only some polished stone tools, wood and other things. So the Panama capuchin shows "human behavior", is it time to arouse human vigilance?
In fact, unlike other primates, human beings are also changing their body structure during evolution. For example, humans and chimpanzees have only about 1% difference in genes, which means that about 99% of the genes are the same, and there is also a tendency to "walk upright", which was once considered a "transitional human race", and even some biologists have conducted "ape hybridization" experiments, but due to reproductive isolation or other reasons without results.
But because the brain capacity of humans is 3 times that of chimpanzees, even if the genetic similarity is only 1%, there are two very different directions in the evolutionary process, humans evolve to a higher level, and chimpanzees have been imitating the road.
We return to the question of "using stone tools", in fact, whether to judge "entering the Stone Age" or not is not only reflected in the word "use", but also reflected in the word "manufacturing", that is, whether stone tools can be obtained through polishing.
The Panamanian capuchin is simply the use of tools such as stones, not through polishing and making, so it cannot be judged as "entering the Stone Age".
Moreover, fire is also a tool and natural force, and the use of fire is also a necessary condition for judging that human beings have entered the Stone Age. The use of fire, not only can well resist the attack of the beast, but also can expand the type, source and activity area of food, while changing from eating raw food to eating cooked food, which can greatly reduce bacterial or viral infections, which is conducive to enhancing physical fitness, promoting brain development and so on.
Scientists have conducted extensive follow-up surveys and studies on the Panamanian capuchin, but there is no record that such monkeys have the ability to "drill wood for fire."
Finally, a simple summary:
The history of human civilization is only about 10,000 years, but it can develop in such a short period of time, "nine days to catch the moon, five oceans to catch turtles", build a space station, etc., which is actually closely related to the "evolutionary history" of early human beings for millions of years, according to the "rhetoric" of scientists, human beings have unique "smart genes", and in the process of differentiation, "choose the right path", so as to have the opportunity to create the "first civilization" on the earth.
The black hat hanging monkey "bumping face" humans, Panama capuchin showing "human behavior" is just some "coincidence" phenomenon, and there are not a few such phenomena, such as the story of "crow drinking water", sea otters smashing shellfish with stones as chopping boards, "flat-headed brother" honey badgers will escape with the help of brooms, and so on.
But when we judge whether a creature has entered the Stone Age, one is whether it has the ability to polish and make tools, not just simply use some "natural tools", and the other is that fire is a special tool, and the use of fire is also the key to helping human beings transition to an advanced civilization.
Therefore, human beings do not have to worry about the "human performance" of animals, if there are such signs, in order to reach the current level of human civilization may also have to go through millions of years of evolution, by which time humans may have already achieved interstellar crossing, colonization of Mars or to develop more distant planets.
