Please use concise words to summarize from a scientific point of view how human beings originated

Walking upright, freeing your hands, using tools and fire, conquered the animal kingdom.

Modern science believes that life is the movement form of matter, and the cell is the basic unit of life, which is a material system composed of biological macromolecules such as proteins, nucleic acids, and lipids.

According to archaeologists' analysis of fossils, the earliest cells on Earth appeared 3.2 billion years ago. In the hundreds of millions of years that followed, with the changes in nature and the progress of organisms, cells changed from simple to complex, from low to high, and a variety of organisms were formed.

There are more than 1 million species of animals and more than 300,000 species of plants, including large behemoths and whales, and small viruses and bacteria that are invisible to the naked eye.

And in a long period of time, creatures during the transition from apes to humans learned to make tools in the process of long-term use of natural tools, and the manufacture of tools means conscious activity after thinking, and this conscious agency is the most important difference between man and animal, and it is a leap from the transition process from ape to man, which marks the end of the transition period from ape to man, and the development of man has entered the stage of fully formed man.

Modern science has come up with a summary of the origin of human beings with the help of high technology, and believes that human beings have been around for more than 300 years and a half.

Learn about what modern science understands about the origins of human beings and write a short introduction. This is written by professionals who discovered the Peking Man skullization period from our country, and we began to study this at that time.

Science now believes that the origin of human life is the ocean.

Because now science can study a lot of human origins and human beings, and scientific and technological means are very important to develop the evolution of human beings.

Modern science's understanding of the origin of human beings, write a short introduction, then modern science plays an important role in people's um, material life and um, and so on.

For the understanding of the origin of mankind, you can write about some things that you know. Speaking from this origin.

In the distant primitive times of antiquity, human ancestors, like other animals, did not have language, and communication with each other was only expressed by body movements. The earliest language of human ancestors (apes) was monophonic interjections, such as "hey", "ah", "wow", "ha", etc., and then developed into two-tone words, and then after millions of years of evolution and development, it was not until the late Yuchao era (about 100,000 years ago) that there was a primary human language.

By the time of the Suiren clan, human language was already quite abundant. But at this time, there was no writing, and if there was something important to remember, it could only be remembered by placing stones, which we called "rock-stacking notes".

The method of "piling stones" is to represent different things based on the size, number, method and location of the stones. This method is cumbersome, unmanageable, and easily broken. Later, the Weaver Girl of the Suiren Clan's Weaver Girl invented the rope rubbing technique, and then invented the "Knotted Rope Chronicle".

"Knotted rope note" is a thin rope made of soft and flexible bark, and then dozens of strings are neatly hung in one place, and knotted on top of the note. Big things are tied in big knots, small things are tied in small knots, what happens first is tied on the inside, and what happens later is tied on the outside. In order to be able to record more things, the Weaver Girl used the natural colors of plants to dye the strings into various colors, each color representing a different type of thing, so as to make the things remembered more clear.

Since the "knotted rope note" is more convenient and easier to keep, it replaces the "rockfill note".

In the late Suiren period (10,000 years ago), the Suiren invented the earliest "deed inscription symbol writing".

Writing is the record of language, human language originated about 105,000 years ago, and the earliest written history can only be traced back about 7,000 years. With writing, human knowledge can be recorded and passed down without distortion. Therefore, the production of writing has promoted human social civilization and the development of natural science, and has played a major role that cannot be replaced by any medium.

Tired words, human words, human words, human words.

Now there is only one kind of universal recognition: according to Dahl.

According to the theory of evolution, all life is formed by inorganic matter in nature in a suitable environment through extremely long and complex reactions. Organic matter forms unicellular animals, and single-celled animals give rise to multicellular animals, just like trees, which start with only trunks and branch more ...... the higher they goHumans are the last ones. To put it simply, this is probably the case, if you want to know more details, then Darwin's theory of evolution, you read it, it should be the most authoritative.

Regarding the theory of human origins, the following have been proposed:

Creationism: Asian Origins.

Theory of the Origin of the Sea.

African multi-source.

African Monogenic Theory.

Theory of extraterrestrial origins.

Creationism: It means that God created man, the most famous of which is legend"God made man"In medieval Europe, whoever dared to question the authenticity of this legend was to be killed.

Asian Origin Theory: Since Asia is the origin of higher apes, some people believe that humans also originated in Asia, and with a series of discoveries such as Javanese ape man and Peking man, this theory flourished. However, with the comprehensive archaeology of ancient humans in Africa, and the fossils of ancient apes in China (such as Lufeng Australopithecus, great apes) are not thought to be the ancestors of humans"Asian Origins"It's in decline, and I don't know how many are left here"Patriots"Support for this doctrine ......

The Theory of the Origin of the Sea: For a long time, we have not found human fossils dating back to 8 million to 4 million years ago, and some of the physiological characteristics of humans are close to those of marine mammals, so some people believe that our ancestors lived in the sea during this time. However, with a series of discoveries in recent years, the so-called"Fossil blank period"has been filled in, who else will support this doctrine?

African polygology: With the comprehensive archaeology of ancient humans in Africa, many fossils of ancient humans and hominids have been found in Africa"Africa is the origin of humanity"There is no opposition to this doctrine in the mainstream scientific community. The theory of African origins has"Multi-source theory"with"Single-source theory"The multi-origin theory holds that after human beings evolved to the stage of Homo erectus, they spread to the whole world, and then evolved separately, and with the frequent interaction of human beings, different ancient humans began to mix and hybridize, and became the current variety of modern humans.

Photo"Multi-source theory"Chinese Homo erectus such as Peking Man is still the ancestor of modern Chinese. "African multi-source. "It is the current mainstream theory of the origin of human beings in Chinese.

The "multi-region origin theory" holds that modern humans appeared and evolved in four regions, and that there was genetic exchange between each region. The writing of prehistoric evolutionary history is completely chaotic. Until now, we have not been able to draw a definitive conclusion about the origin of ancestors in the history of biological evolution.

The where, when, genealogical relationships between human populations, and even migrations of modern humans are not open in detail. After all, sporadic fossil discoveries have not yet been conclusive.

One god created nearly 20,000 stars, and third, Nuwa sacrificed. Monkey first.

Nuwa made it, God made it, a monkey turned into a monkey, and it came from an alien planet.

Human writing is the initial stage of the development of human writing, which is vividly communicated and recorded. But the writings of many peoples in ancient times were buried before they went beyond this stage. Writing, to be precise, is a kind of reference to paintings and sculptures that began to be cast in the marking time"Text", the oldest ancient scientists confirm that pictorial writing appeared in the plains of Mesopotamia in 3500 BC, one of the cradles of human civilization, and that subtitles appeared when the Sumerians established a slave regime; Later, this script was also used in ancient Egypt, which was known as hieroglyphs.

Hieroglyphs are mainly written in:"things"The image of the writing. When human social activities are gradually expanding, and various economic and military activities are frequent, this kind of pictorial writing cannot fully express what human beings want to express. At this time, a new type of pictorial writing that can express complex concepts and meanings came into being—cuneiform.

When the pictorial symbol is simplified enough to form a late-fitting correspondence with the language, the original script is formed. In "Introduction to Paleography", Tang Lan divides ancient Chinese characters into four systems. Yin Shang, Western Zhou, Six Kingdoms and Qin.

From oracle bone inscriptions to small seals, Chinese characters have undergone a transformation from a detailed description of images to a simplified and depicted direction, and the form has gradually detached itself from the concrete image of things. The Chinese characters of this period are also known as paleographies. Words are actually a medium through which people communicate through visible symbols that are routinely chanted.

It is a system of written symbols in which people record language. The history of human writing runs through the entire history of visual connections from the early pictorial writing to the alphabetic writing.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

At the beginning of human writing, stones were used as marks, which slowly evolved into lines, and then used turbulent objects to mark and write-off, and finally invented digital sliding and Chinese characters.

People want to record some things in the process of development, want to communicate better, at this time they will use some pictures to record some blind things, and slowly develop into a literary and family character.

Human writing began with oracle bone inscriptions, because the earliest written characters were oracle bone inscriptions, and it was also from oracle bones that began to evolve writing.
