2. The 600-word composition on human evolution is boring. There are many myths about God creating man on the Internet.
I first looked up the myth that God created human beings. It is said that about 50 thousand years ago, a group of aliens came to the earth with high knowledge. When they found that the gravity of the earth was not suitable for them to live in, they chose the energetic and clever female ape on the earth and injected it into the hearts of astronauts for hybridization, thus giving birth to the earthlings. There is also the saying that Prometheus created man. Prometheus, the pioneer, landed on the earth. He is a descendant of God. He is clever and wise. Knowing that the seeds of the gods were hidden in the soil, he moistened them with river water and shaped them into human shapes. He absorbed good and evil from the hearts of all kinds of animals and sealed them in people's chest. His good friends commanded the soul of the goddess Athena to make a sacred call to creatures with only half life, and then he formed a man. The first grade composition "600 words of human evolution". God has deepened the creation of human beings, and some of them have created human beings from the soil.
Then, the teacher led us to see the process of human evolution. 70 million to 8 million years ago, humans were archaeopteryx, the same ancestor of humans and apes, and they began to evolve from different directions. From 4.2 million to 65.438+0 million years ago, Archaeopteryx evolved into Australopithecus, which was the most primitive hominid representative differentiated from apes, including apes and apes. They represent the early ape-man stage in human evolutionary history. Slowly, they evolved into Homo erectus. Yuanmou man was the earliest Homo erectus discovered by China 10,000 years ago, Lantian man discovered it later, and Neanderthals first discovered it among early Homo sapiens. The skull is flat-headed, with a capacity of 900-65,438+0,300ml. The process of human evolution is very complicated, although scientists have roughly guessed it, but
The charm of human origin and evolution leads us to explore, and in the future, there will be more mysteries waiting for us to solve.
The 3.300-word "human evolution" breeds thousands of lives on this beautiful earth. Man can be regarded as one of the excellent species. The wisdom of human beings is unmatched by other animals. In the process of evolution for thousands of years, they are constantly changing themselves and the whole world. However, nature is joking with people-where did humans come from? This question seems simple, but in fact it is puzzling and puzzling. It is a shackle that human beings have not solved so far ... For thousands of years, people have been pursuing their roots. However, due to ancient people's ignorance of science, their understanding of themselves can only stay in fantasy. In ancient China, Pangu created the world, and the story of Nu Wa creating man has been circulated. People think they are just boring immortals squeezed out of mud. People think that human beings originated here. This idea has been buried in the fertile soil of China for thousands of years ... In the ancient west, people believed in God, and God was the supreme true god. People think that human beings have been active in this land since God created Adam and Eve. To this day, people still hold great reverence for God and think that God is the creator of mankind. This idea has also taken root in the west and is still developing vigorously. These are the so-called creationism. It is the definition that human beings give themselves in their ignorant childhood. They add a mysterious veil to the problem of human origin, and make the dream of root-seeking more urgent. Time flies, gradually, with the mastery of scientific knowledge, the world suddenly becomes a world dominated by human beings. But the pursuit of mankind has not stopped and will not stop. It was not until 1860 that Darwin put forward his bold theory that people broke the previous ignorance.
4. Articles on human evolution 1, arboreal people
In the 1980s, Dixon, a famous British paleontologist, wrote a book "The Future of Mankind", in which he said, "... an animal with scales and red blood vessels, grabbed a mossy trunk with its powerful claws and waited quietly for dawn on a branch 30 meters above the ground. When the rising sun shone the first ray of sunlight on this lifeless and desolate land, he immediately unfolded his mushroom-shaped flippers to absorb the heat of the sun. When he got enough heat energy, he fell from the tree, revealing a large and thick blood vessel, which grew out of his abdomen and reached into the lake to absorb the blue algae and green algae in the lake. At this time, you can clearly see his face: a human face. This strange animal is the future human being who will live on the earth after 500,000 years. "
Why did mankind go into decline?
Dixon's explanation was quite unexpected. He said that the key reason is the development of medical science. It's a little incredible, but the reason is simple. For example, 100 years ago, people who were backward in medicine and suffered from common diseases such as asthma, kidney disease, tuberculosis and diabetes often died before they got married, not to mention other more serious diseases. This kind of death is very similar to screening good varieties. Sick or unhealthy people die early, don't get married and have no offspring, just like flat and stunted seeds are naturally eliminated, while healthy people are like full seeds.
This is a sad cycle. In this way, people's limbs will decline greatly, and the trunk and limbs will even become useless organs, leaving only the brain, sensory organs and reproductive organs.
2. dinosaur man
Dickson's theory of human evolution is pessimistic, and his language will inevitably decline, but many scientists are skeptical and opposed to it.
Canadian anthropologists Lu Se and Sekin are advocates of linear evolution. What is linear evolution? Simply put, human beings will become stronger and stronger, which is just the opposite of Dixon's pessimistic argument. According to this theory, 500,000 years later, human beings will become very, very powerful "Superman".
This statement also has some truth.
Since the first group of Homo erectus appeared in the grasslands of East Africa, human beings have begun a long evolutionary process. His brain is getting bigger and smarter. The brain of modern people is almost three times that of ancient apes. Also, people's feet begin to adapt to running and walking upright, so that their hands can be liberated and become very dexterous. In addition, human beings can create and use complex tools and develop languages so that they can learn and use other people's creative achievements. Over time, year after year, human beings rely more on brain power than physical strength. According to this way of evolution, it can be predicted that after 500,000 years, the human brain will be much bigger than ours, but the limbs will gradually degenerate and eventually become a big head and a small body.
The two scientists also created a strange-looking dinosaur man. They say that some kinds of dinosaurs evolved perfectly. For example, there is a carnivorous dinosaur that evolved very fast. If there were no catastrophic extinction of dinosaurs, this carnivorous dinosaur would have evolved into an intelligent creature-dinosaur man. Dinosaurs have big heads, big eyes and slender limbs, which are very similar to imaginary future people.
But most scientists are willing to accept the theory of stable human evolution.
They believe that human evolution, like the evolution of other animals, does not evolve in a straight line. Simple body shape changes or brain development cannot be used as the main symbol of human evolution. For example, in the last 500,000 years, human body shape changes and brain volume increase are limited, but human intelligence and social progress have been highly developed. Therefore, the proportion of human body structure in the future will not be much different from that of human beings today.
Then some people may ask, isn't it self-contradictory that human wisdom is developing with each passing day, while human physique is maintaining a long-term static balance and showing a relatively conservative stability? In fact, it is not contradictory, because many organisms have such a relatively stable development period in the long evolutionary years, which is very beneficial to the preservation of biological species. Similarly, the static form of human body is beneficial at least for the present, so what about the future? Let's take a look at the history after the birth of mankind. In those 6.5438+million years, several different animals competed in evolution and wanted to be the masters of the earth, but in the end, human beings gained the advantage, not only survived, but also became the most successful one in the evolution of life on the earth. This history shows that human beings have many advantages, and maintaining these advantages is of course beneficial to human survival.
What will human beings become in the future? The three viewpoints are completely different, but today, no one can prove which viewpoint is completely correct, because they are only scientific predictions.

7. Write an article according to the origin of human beings. Who will help me? Since human civilization, the views of the global scientific community on life and the origin of human beings have been debated endlessly. So far, no theory is absolutely convincing. The origin of human beings is a difficult problem in scientific research, because it involves a wide range of disciplines and is inextricably linked with astronomy, physics, geography, chemistry, microbiology, zoology, botany, marine biology, philosophy, logic, materialism, evolution, archaeology and geology. So far, Darwin's theory of evolution recognized by the scientific community has been basically confirmed in practice, but there are still many unsolved mysteries, such as the origin of single cells, the origin of animals and plants, the origin of human beings, and the life belt.
At present, there are many disciplines involved in the study of human origin in the world, all of which focus on the origin of life and conduct research and exploration from the perspective of their own disciplines; This paper comprehensively analyzes the mystery of the origin of life from the macroscopic view of the universe, material movement, evolution and human practice. Because life is not only the life of the earth, but also the life of the universe. Scientists who used to study the origin of life and human beings mostly studied the origin of living things from the perspective of the earth. People should understand that the earth is one of the planets in the solar system, and all the planets in the solar system are controlled by the sun. Therefore, the earth is directly related to the material movement and change of the whole solar system. At the same time, at present, most biological species on the earth have experienced a long evolutionary process, and some even have an evolutionary history of millions of years, and various species have added a variety of organic substances. The creatures we can see on the earth now are all excellent people with strong survival ability in the process of survival of the fittest, and they are all staged ecological manifestations formed by various species in the long process of continuous evolution. In the past, because the departments were too scattered, the related links around the origin of life were separated by different majors. In this way, we are restricted from finding a clear statement about the origin of life. Only when we innovate will we have breakthroughs and new creations. This is the mission of each of us who studies life and human science.
In what form does matter express its existence? Existence has its function and rationality. If matter is static, then we can't know it, and there is no human itself. Matter is in motion, and the motion of matter must have its physical principle. In theory, the movement of any substance has a beginning and an end, and it has its function and purpose. The movement of matter should have its power source or starter, and the power source of matter movement is the energy of matter. So, how is energy generated and transformed? How can organic matter be transformed into inorganic matter, and how can inorganic matter be transformed into organic matter to realize energy regeneration? This is the central content of my research in recent twenty years. The research results of this paper can basically clarify the mystery of life and the origin of human beings, provide a new exploration platform for people to study the origin of life, and provide some new ideas and viewpoints, so that human beings can re-understand themselves, the world and the universe. If I can play a little role in attracting jade, this will realize my wish.
8. How did humans evolve? The word 150 is pregnant with thousands of lives on this beautiful earth.
Man can be regarded as one of the excellent species. The wisdom of human beings is unmatched by other animals.
In thousands of years of evolution, they constantly change themselves and the whole world at the same time. However, nature played a joke on people-where did humans come from? This question seems simple, but in fact it is puzzling and puzzling.
It is a shackle that human beings have not solved so far ... for thousands of years, people have been looking for their roots. However, due to the ignorance of science in ancient times, people's understanding of themselves can only stay in fantasy.
In ancient times, the story that China was among the people, Pangu created heaven and earth, and Nu Wa created mankind has been circulated. People think they are just boring immortals, making dolls out of mud. They worship gods and believe that people come from this.
This idea has been buried in the fertile soil of China for thousands of years ... In the ancient west, people believed in God, and God was the supreme true god. People think that human beings have been active on this earth since God created Adam and Eve.
To this day, people still hold great reverence for God and think that God is the creator of mankind. This idea has also taken root in the west and is still developing vigorously.
These are the so-called "creationism", which is a definition given by human beings in their ignorant childhood. They add a mysterious veil to the question of human origin, and make the dream of human longing for roots more urgent.
Time flies, gradually, with the mastery of scientific knowledge, the world suddenly becomes a world dominated by human beings. But the pursuit of mankind has not stopped and will not stop.
It was not until 1860 that Darwin's bold theory broke people's previous ignorance. Has entered a brand-new stage.
With the excavation of more and more human fossils, people's understanding of themselves has gradually become clear, and the fog on their heads has gradually dispersed, but they have drawn a bigger question mark. "Australopithecus theory" is the earliest viewpoint that human beings evolved from apes to Australopithecus, homo habilis, Homo erectus and Homo sapiens step by step.
Some fossils increase the reliability of this theory. However, with the deepening of the research on human body, more mysteries hang over people's heads, and the subsequent "sea ape theory" and "alien theory" make people's research on themselves more diversified.
People constantly put forward new conjectures through their own research. Up to now, there are still different opinions and no conclusion.
However, people still regard "Australopithecus theory" as the basic theory of human origin and continue to explore. Although there is no conclusion now, with the continuous development of the times, people's understanding of themselves will gradually become more reasonable.
Is human being the perfect masterpiece of the gods in the sky, or is it the product of the uncanny workmanship of nature? The mystery of human origin will eventually be solved. The key to unlock this chain is not far away, waiting for the arrival of mankind.
9. How to write the outline of the essay "The Story of Reading" is to write a short story about your reading. For example, when I was a child, I liked reading. When I meet a new book, I will read it endlessly. I read books in kindergarten, and after I learned to spell, I read phonetic stories. I never let go of any of the stories such as Andersen's Fairy Tales, Grimm's Fairy Tales and Arabian Nights. When I was ten years old. I started reading famous books. My bookshelf is also full of Chinese and foreign masterpieces, besides China and Four Great Classical Novels, there are Selected Works of Bing Xin, Zhu Ziqing's Prose Collection, Education of Love, How Steel was Tempered, and so on. I remember once, my mother gave me a book coupon from 200 yuan, which meant that I could read many new books again. My mother gave me a book coupon of 100 yuan. My dream "One hundred mothers who touched primary school students" has been sold out. I came home regretfully and hung my head all day. Mother's cordial greetings finally broke through my sad dam. I burst into tears and gushed: "One hundred mothers who touched primary school students have sold out, so I can't stand it!" Mom smiled and said, "That's why I'm crying. Don't cry. Mom will fix it for you! " "The next day, my mother came back from work with an extra bag in her hand. My mother put the parcel in front of me and said easily, "Open it. "ah! It turned out to be "One hundred mothers who touched primary school students"! Mom really keeps her word, and it's immediate! I embraced my mother with open arms. Immediately, I picked up the book and read it sweetly. Reading is sweet. Let this sweet taste accompany me all my life! The short story books I read are like a compass in the desert and a Polaris in the night, always silently guiding people and guiding the right direction. The book and I are predestined friends. Growing up, I always saw grandpa's books neatly placed on the bookcase, which was a pile of famous books. Every time I see grandpa holding a book and analyzing it with relish, my heart is always itchy and eager to try. Full of a child's extreme curiosity and even some excitement. Finally, one day, under the urging of my little head's repeated thinking and curiosity, I got up my courage for the first time and said to my grandfather, "Grandpa, you can share it with me and tell me a short story in the book every day, ok?" Grandpa readily agreed to my request. At first, I felt satisfied and happy: I finally got what I wanted! But patience seems to be unbearable to tell a story one day, talking about the time and efficiency before going to bed. At this time, I found the only and most efficient way: reading by myself. Perhaps it is because I am young and don't know many words, so it is undoubtedly very difficult to read grandpa's old books. Not to mention the content, I have been confused by my unfamiliarity with the text, and I have asked my grandfather for help many times. Every time I see this scene, every time I hear this scene, my grandfather is always reluctant to pick up the three-character classic that I have read thoroughly, but it makes me more motivated to look it up. Grandpa had to buy me a children's edition of the famous book. After these twists and turns, my reading process finally started, really started. Ever since grandpa bought that book, I've been immersed in it, like drunk and unable to extricate myself. I have been absorbing the knowledge in books like a sponge. I feel the joy of reading. I found that books are people's silent teachers and intimate friends, and have been silently enlightening people. Reading can cultivate sentiment, enrich knowledge and broaden your mind. Let's join hands with books and work together! My Reading Story I have loved reading since I was a child. My room is full of books, including China classical Four Great Classical Novels, China children's encyclopedia and historical records, as well as many magazines, comics and other periodicals. According to my mother, I loved listening to stories when I was one year old. I always listened to them for an hour or two before going to bed every night. Because I loved listening to stories when I was a child, I knew a lot when I first went to kindergarten. Let my mother buy books to read. The book Two Little Flowers tells me that one can't be selfish. After the little girl picked the flowers home, the painful appearance of the flowers was still imprinted on my mind. Gradually, I fell in love with reading. Now, reading has become an indispensable part of my life. I will read books as soon as I have time. I like reading Journey to the West, because from here I know that a person should be brave and kind. I must have the perseverance to stick it out. I must be brave enough to overcome difficulties, and I will win in the end. I grow up day by day and read more and more books. Every time I go to the bookstore, I want to buy a lot of books, but the prices of books are too expensive. Later, my mother went to the library and got me a library card to satisfy my reading desire, so I borrowed books from the library every weekend. Reading when danger came taught me to face it bravely Reading The Mystery of Life made me understand the evolutionary history of human beings and many people's strange living habits. I like reading very much. I love reading all kinds of books, and I have to read a book when I go to the toilet. My mother says I like reading.
