So how should you write this type of composition? The following is a selection of 5 400-word explanatory essays about human beings that I compiled. I hope it can help everyone. Selected 5 explanatory essays about human beings of 400 words 1
The idea that Africa is the cradle of humankind was first proposed by Darwin. He made bold speculations in his book "The Origin of Man and Sexual Selection" published in 1871. Another evolutionist, Hegel, argued in his book "Natural Creation History" published in 1863 that humans originated in South Asia, and also drew a diagram showing the migration paths of various human species today from the center of South Asia. In addition, there are Central Asian theory, North Asian theory and European theory. Because the cradle of mankind is swaying across continents as human fossils are constantly being unearthed.
Europe, especially Western Europe, was once considered the birthplace of mankind. There were 116 individuals from 1823 to 1925, including the ape-human stage Homo heidelbergensis. There have been even more discoveries of human bones from the Neolithic Age, 236 cases. Therefore, when people open the map, they see that Europe is full of ancient human ruins. At that time, except for the Javanese ape man, no ancient human sites had been found in other parts of Asia and Africa. Also, the earliest fossil of an ancient ape discovered was also unearthed in Europe, namely the fossil of the forest ape discovered in France in 1856. In addition, in the 1920s, the scam of "Pirddown Man" was very noisy (Pirddown Man was regarded by some scholars as the earliest people, and even called him "Dawn Man". It was finally revealed that the so-called "Dawn Man", It turned out to be a fake that combined a Neolithic human skull and a modern ape mandible), so many people at the time believed that the center of human origin was in Western Europe. However, with the discovery of more human fossils in Asia and Africa, the theory of Europe, the cradle of mankind, gradually faded away from the stage.
The discovery of "Peking Man" not only saved the Javanese Homo erectus, but also made the theory of Central Asian origins more popular.
In 1887, Dutch anatomist Dubois, eager to find the fossil remains of early humans, came to the Indonesian island of Java and actually found fossils of primitive humans. In 1890, in a place called Trinil, a fragment of the lower jaw was first found, and the following year a skull was discovered. This is the famous "Javanese" skull No. 1. In 1892, another thigh bone was found not far away. After studying these materials, Dubois believed that they belonged to the same individual and were the "missing link" between humans and apes that people were looking for.
The discovery of the Javanese Homo erectus has shaken up the theory of South Asia. However, Dubois' discovery was opposed by many people, the strongest opposition coming from the church. The church insists that the ancestor of mankind should be Adam. How could it be an ape-man?
In 1911, paleontologist Matthew listed species in his book "Climate and Evolution". There are many reasons to advocate that the Central Asian Plateau is the cradle of mankind. The reasons are: first, the natural environment in Central Asia has become unsuitable for survival due to the rise of the Himalayas. However, for animal evolution, the response to stimulation is the most beneficial, so these external stimuli can promote the formation of humans; second, The migration pattern of mammals is often such that the least progressive types are excluded from the dispersal center, while the most powerful types stay and continue to develop near their place of origin. Therefore, the most primitive humans can be found in areas far away from their hometowns. . The early human fossils discovered at that time, such as Heidelbergensis and Javanese Homo erectus, are consistent with this hypothesis.

There are many myths and stories about the "origin of human beings". For example: "Nu Wa created man", "In the Garden of Eden"... They are all wrong explanations of human evolution. However, some people still firmly believe in this wrong explanation. Why? Because they have extraordinary charm.
The charm of mythical stories about "the origin of mankind" lies in the fact that myths themselves are rich in imagination, allowing readers to fantasize, break away from reality, and enter an illusory realm, making it easy for people to fantasize. No matter adults or children, they all have a special liking for this kind of article. The fairy tales are full of innocence, and the things that are not are written down. In addition to reality, people can also enter another illusory world. Just like in "Nuwa Creates Man", it is written that Nuwa is a god with great supernatural powers and can also create people from clay. As far as "God" is concerned, a big mistake has been made. Are there really gods in the world? No. But it is there in the article, and it has great magical power, and it can write down what is not there. This kind of imagination is boldly written. Let’s talk about “making people out of clay” again. OK? It's impossible. If you don't believe me, try it. It's completely nonsense. But the author wrote it again, and people still like it because it is not true, and people like the plot more and more. Because there is enough space for everyone to freely use their imagination. Unlike Xi'an where people can only accept it without miracles happening, myths do exist. Otherwise, why is it called "God's Word"?
This is the charm of fairy tales. Are you becoming more and more fond of "mythical" stories? 5 selected explanatory essays about human beings, 400 words each 3
Where did humans come from? This is a mystery, a 600-word essay on the evolution of humans. But with mythical answers, I won't feel bored. There are many myths on the Internet about God’s creation of human beings.
I first looked up the myth of God’s creation of human beings. It is said that about 50,000 years ago, a group of aliens came to the earth. They had a high degree of knowledge. When they found that the gravitational factors of the earth were not suitable for them to live, they chose the energetic female apes with higher intelligence on the earth. , injecting the hearts of spacemen for hybridization, which produced earthlings. In addition, there is also the theory that Prometheus created man. The Illuminati Prometheus landed on the earth. He was a descendant of the gods. He was alert and wise. He knew that the seeds of the gods were hidden in the soil, so he moistened them with river water and molded them into human shapes. He learned from various animals Taking good and evil into his heart and sealing them in the human chest, his good friend commanded the divine soul of the goddess Athena to send the sacred call of the soul to the creature that was only half alive, and then formed a human being. God created humans in many ways. Some of them were created from soil, some came by calling, and some existed in heaven and earth.
Then, the teacher led us to investigate the process of human evolution. Between 70 million and 8 million years ago, humans were ancient apes, the common ancestor of humans and great apes. They began to evolve in different directions. From 4.2 million BC to 1 million BC, Homininus evolved into Australopithecus, which is the most primitive representative of the hominid family that differentiated from apes and has mixed characteristics of apes and humans. At this time, Australopithecus could walk upright and then evolved into humans. They represented the early ape-man stage in the history of human evolution. Slowly, it evolved into Homo erectus. Yuanmou Man 10,000 years ago was the earliest Homo erectus discovered in China. Later important discoveries included Lantian Man. The earliest discovered among early Homo sapiens was Neanderthal, with a skull of The flat-head type has a capacity of 900-1300 ml. The evolutionary process of human beings is very complicated. Although scientists have roughly understood and speculated on it, they are more interested in leaving it to the successors of our generation to explore and discover.
The charm of human origin and evolution guides us to explore. In the future, there will be more mysteries waiting for us to unravel. Selected 5 400-word explanatory essays about human beings 4
The origin of human beings can be said to be the most vexing academic issue, whether it is anthropologists, archaeologists, historians, or biology Scientists, chemists, and even philosophers and religious scientists have all conducted research on the origin of human beings from various angles. However, so far, there is still no most convincing explanation.
Various ethnic groups have quite rich myths and legends about the origin of human beings. Some of them are quite similar, but of course there are also many differences. Among these myths, it is very interesting that we can find that there are differences with the theory of evolution. A place of coincidence.
Summarizing various myths, the origin of human beings can be divided into five types: "called out", "originally existing", "changed from plants", "changed from animals" and "made from soil". Let’s describe them separately.
"Egyptian Mythology" says that human beings are called out by gods. Since ancient times, Egypt has been a mysterious place. It is the most self-enclosed among all ancient countries. It has its own way of life, and it is difficult for external civilization to affect it. Therefore, its theory of human origin is also different from other theories. The people are different.
The Egyptians believed that long before Egypt appeared in the world, the almighty god "NU" existed. He created everything in the world. When he called "Subi", the wind came into being. ; Calling "Tefuna", there will be rain; calling "Habi", the Nile River will flow through Egypt. He calls again and again, and all things appear one by one. Finally, he speaks "man and woman", and in a blink of an eye, Egypt and it was filled with many people.
After the work of creation was completed, Nu transformed himself into a man's shape and became the first Pharaoh, ruling the human race on earth and creating peace and prosperity.
Myths that have always existed in human beings are scattered among the North American Indians and the Maori people of New Zealand. Indian myths say that God created the heaven and the earth, and then led humans up from the underground to live on the earth. Maori mythology says that "Ranchi" and "Baba" are heaven and earth, the source of all things. At that time, heaven and earth were not separated, and everything was dark. His son longed for light, so he pushed the heaven and earth away with force, and light appeared. Human beings who have always been hidden in the darkness are discovered. It turns out that they are also born from heaven and earth.
It is a Germanic myth that humans are transformed from plants. It says that the god Odin and other gods were walking on the beach one day and saw two trees growing on the sandbank, one of which looked like a tree. The other tree was majestic, and the other tree had a graceful posture, so he ordered the two trees to be cut down and made into men and women respectively. Odin first gave life to them, and the other gods gave them reason, language, blood, skin color, etc., becoming the ancestors of the Germans.
The myth that humans were transformed from animals is quite common. Australian mythology says that humans transformed from lizards; American mythology says that humans transformed from mountain dogs, beavers, apes, etc.; Greek mythology also says that a certain tribe of people transformed from swans, and a certain tribe of people transformed from cows.
From this myth of "animals turning into humans", we can find something very close to the theory of evolution. Especially in American mythology, it is said that humans were transformed from apes, which is completely consistent with the theory of evolution. This coincidence , very intriguing.
There are several myths about the origin of human beings in our country. The earliest one is "Huainanzi Spiritual Chapter": "There are two gods (yin and yang) mixed together, and they are in the camp of heaven... Similar to Qi. Insects (turbid gases turn into insects, fish, birds and beasts), and essence becomes humans (pure gases turn into humans). ” This argument did not receive much attention.
A later theory refers to the fact that when Pangu was dying and transformed into all things, the parasites on his body turned into humans. Yishi Volume 1 quotes the Five Movement Calendar Years: "The insects in (Pangu's) body turned into humans (people) due to the influence of the wind." ” This statement has not spread.
Another theory is that human beings were created by the Yellow Emperor, and then were given limbs and five senses by other gods, Shang Pian and Mulberry. See Huainanzi's chapter on Lin: "The Yellow Emperor gave birth to yin and yang, and Shang Pian gave birth to ears and eyes. Sang Linsheng’s arms and hands…. "This statement is very interesting and very similar to what Germanic said. Unfortunately, what kind of gods Shang Pian and Sang Lin are are not described in other ancient books, leaving only a mystery.
Among all myths, the theory of "creating man from clay" is the most common and the most popular. For example, New Zealand mythology says that man is made of red clay and his own blood by the god Tiki; Mera The Nicene people also said this; Greek mythology said that God took out earth and fire from the inside of the earth, sent the two brothers Prometheus and Epimetheus to create animals and humans respectively, and gave humans species. personality and wisdom.
The Maidu Indians in western North America believe that after the "founder of the earth" created trees, birds and beasts, he said, "I am going to create humans." ” Then he took some dark red soil and mixed it with water to make a man and a woman.
Among all myths, the most fascinating stories about the creation of humans from clay are those of our country’s Nuwa and the God of Jewish mythology (the Bible).
It is said that after Pangu opened up the world, I don’t know how many years passed, but Nuwa suddenly appeared between the heaven and the earth. Nuwa felt lonely in this desolate world. One day, she looked at the water and saw herself. She thought it would be great if there were a few people like her in the world who could talk to each other, so she unconsciously grabbed the soil. , mixed with water, made a clay doll according to his own shape, placed it on the ground, and when the wind blew it, it became a living thing, so he named it "man".
It turns out that Nuwa continued to create humans one after another, but the progress was slow, and she finally felt that it was difficult. When she wanted to create humans quickly to fill the vast earth, he leaned against the cliff and easily He took off the cane and stirred it lazily in the mud mixed with water. Then he shook the cane and scattered a lot of mud dots. These mud dots fell on the ground. When the wind blew, they all turned into people, so he kept going. The ground waved the cane, and the number of people on the ground continued to increase.
The story of God’s creation of man in the Bible is recorded in the Book of Genesis in the Old Testament. It is said that God spent five days creating all things on earth. On the sixth day, He said: "Let us create man in our image, according to our likeness..." So he created man from the dust of the ground and breathed life into it. After the man's nostrils, he became a living man and was named Adam.
Soon one of Adam's ribs was taken out and made into a woman. Adam said, "This is bone of my bones and flesh of my flesh. Let me call her woman." 』
In the myths about Nuwa and God creating humans, we can find that the only difference is that they both created humans in their image. This shows that Nuwa and God look similar to humans. . The difference is that the Bible describes women as men. Selected 5 expository essays about human beings, 400 words 5
People will change with the times, and so will their thoughts and minds. .
I had such a dream that night. I was sleeping, and suddenly someone woke me up in my sleep. "Yanyan, Yanyan, get up quickly, it's time to go to school." It was the robot "Bili" who woke me up. When he saw someone getting up, he quickly brought my shoes over. He also helped me comb my hair and gave me all the tools to brush my teeth. If I didn't do it once, he would nag me endlessly, telling me this and that. After a while, mother, father and brother all got up, and he brought the prepared breakfast to the table and said, "Please have a meal."
Ah! Today is a sunny day, the sun is shining brightly. The car came to pick us up from school. It made no noise and did not emit black smoke. There are green trees everywhere and fresh air. This suddenly made me think of the text "Prairie": "This time I have a chance to see the grassland..."
When I got to school, I sat in my seat and turned on the computer. We no longer have to carry that heavy schoolbag, we only need to carry biscuit-sized software. Listen, Zhu Xiaomei from our class is using the computer to ask Teacher Ma: "What is the connection between the three stories about Jiang Xianghe?" Teacher Ma said: "The first story is the development of the second story, and the first two This story is the origin of the last story." Teacher Ma answered so quickly that it was simply indescribable.
After school, I came home and was bored, so I used the computer to surf the Internet and talk to Yu Lirui, play games, play chess, draw pictures... it was so much fun.
How I hope this dream can come true soon!
