evolution of human

Human evolution originated from the forest apes, and gradually developed from primates through a long evolutionary process. It went through four stages: ape humans, primitive humans, intelligent humans, and modern humans. About 65 million years ago, a meteorite with a width of about 16 kilometers hit Earth (the Yucatan Peninsula in Mexico), causing the extinction of two-thirds of animal species, including dinosaurs. Primitive mammals survived and rapidly evolved. About 50 million years ago, primates evolved rapidly, from low-level primates to high-level primates. 33 to 24 million years ago, apes were born from the monkeys of the Old World. Among them, there were ancient apes such as the Aepians (30 million years ago), the Aepians (26 to 28 million years ago), the Dryopians (23 to 10 million years ago), and the Pro-Consulians of East Africa (13 to 12 million years ago). These ancient apes were mostly tree-climbing apes that lived in forests and walked on all fours. The existing apes are divided into African apes (gorillas, chimpanzees, and humans) and Asian apes (gibbon and orangutans), which diverged between 12 million and 15 million years ago. From about 10 million years ago to about 3.8 or more than 2 million years ago, Ramapetus and Auropithecus were fossil representatives of the transition period (although Ramapetus was relatively reasonable as a transition representative). In order to survive, the southern apes, which evolved from the ground apes, began to migrate. They already knew how to use tools and became the overlords of the African grasslands. It was not until the emergence of Homo Erectus 1.8 million years ago that there was almost no excess fat in its body. It ran fast and patiently tracked its prey. After eating high-fat meat, its brain capacity gradually expanded. It also understood mutual understanding and co-survival. Then it moved to a wider world, and Asia and Europe gradually became covered with human footprints. In the process of evolution, the structure of the human body was constantly changing. For example, the number of fingers in humans was five, which might have been preserved in ancient times to meet the needs of survival and development. In the past, men with high Testosterone-level were respected for their physical strength, but in modern society, high Testosterone-level was inverse to the degree of investment in raising children. The human jaw deteriorated with the change of food processing methods. From the strong jaw of ancestors to deal with coarse food, to the gradual deterioration of the jaw due to the use of fire, the popularity of modern industrial food further accelerated this process, resulting in the reduction of jaw space of modern people and the growth of wisdom teeth. The human body temperature dropped by about 0.03 degrees Celsius every ten years, which may be related to the improvement of the modern social environment, medical progress, the reduction of the threat of disease, and the reduction of the need for high body temperature. Human bones began to become sparse after the change in lifestyle 12,000 years ago (from hunting and gathering to farming). The modern sedentary lifestyle continues this trend and may face a higher risk of fractures in the future. Human tolerance to milk products has been increasing. 20,000 years ago, most people were suffering from malnutrition when drinking milk. Now, about 35% of the population can easily digest milk, reflecting the improvement of human diet adaptability.

The evolution of humans can be traced back to ancient times. The specific process is as follows: Primitive humans: about 1.5 billion years ago, primitive humans began to appear. They were the earliest humans with highly developed brains and intelligence. Early humans: About 1.2 billion years ago, early humans began to gradually evolve. They began to use tools to develop complex social structures and learned language. Mammals: Mammals began to appear about 60 million years ago, including Homo Erectus, cavemen, etc. These humans had highly developed brains and intelligence and began to master tools. Humans: About 3 million years ago, humans began to evolve into humans. They began to have more complex body structures, including better endurance and higher intelligence. The emergence of civilization: About 1.5 million years ago, humans began to have civilization. They began to create culture such as writing and religion and began to establish social systems. Modern humans: About 500,000 years ago, modern humans began to appear. They had highly developed brains and intelligence and mastered tools. Human evolution: Human evolution is a continuous process. They constantly evolve to adapt to different environments and constantly develop new technologies and cultures. The evolution of human beings is a complicated process, including the long journey from primitive humans to modern humans, which includes many important events and discoveries.

Nuclear radiation generally did not directly promote human evolution. Although nuclear radiation could cause genetic mutation and mutation, such changes were random and could not be controlled. Evolution was a long process that required many generations to achieve. Under the influence of natural selection, species would gradually adapt to environmental changes, accumulate beneficial characteristics, and thus undergo genetic changes and evolution. Nuclear radiation was not one of the factors of natural selection. It could not replace the role of natural selection and become a driving factor for human evolution. In addition, the negative effects of nuclear radiation on humans may also weaken human survival and reproduction, thus affecting human evolution. Therefore, nuclear radiation not only could not help human evolution, but also posed a serious threat to the survival and development of mankind. There was still a lack of conclusive evidence and scientific research to prove the specific impact of nuclear radiation on human evolution.

Books on the history of human evolution were recommended as follows: 1. Sabiens: A Short History of Humanity by Yuval Noah Harari The Evolution of Humanity by Peter Cooper 3 The Biology of Evolution by James Smith 4. The Evolution of Intelligence by Michael Montagnier The Evolution of the Human Brain by Edward Appleton These books covered different aspects of human evolutionary history, including biology, psychology, and biochemistry.

He didn't quite understand the exact meaning of the phrase " human evolution doesn't involve me." If it was referring to the fact that an individual did not feel involved in the process of human evolution, human evolution was a long process of biological and sociological development based on population. It was the gradual mutation of the entire human population's genes, inheritance, and development under the influence of natural selection and other factors over a long span of time. The life cycle of an individual was extremely short compared to the evolutionary process. Moreover, if the genetic mutation of an individual did not have a widespread impact on the gene pool of the population, it would not be reflected in the evolution of the macro. If there are other meanings, please clarify the question.

I recommend " Unscientific Primitive Man." The primitive genre written by Qian Shu is superb. The protagonist Wang Wei's three views on the primitive society were subverted. The primitive people were tall and mighty, and they were strong enough to hold a tripod. There were also dinosaurs and giant insects. The protagonist relied on modern knowledge to develop his tribe, and the primitive people were also very smart. This book had few bugs and no fantasy settings. The description of primitive people's personalities was very realistic and worth reading. " The Chic Prince Charming " was not bad either. Gu Qian started his carefree life after falling out of love. The story was interesting. My 1995 Little Farm was a great farming novel. The protagonist, Chen Ling, returned to 1995 with the Paradise and lived a rural life. The writing style was experienced and the daily descriptions were real. Although the beginning was a little brutal and the author's updates were slow, it was still worth reading. Hospital 444 was scary. In the ghost story mystery novel written by Black Tinder, the male protagonist, Dai Lin, was a doctor in the strange 444 Hospital, treating the mysterious curse. The terrifying atmosphere was well created, and the plot was first-class. As a Grass God: I'm Invincible, Do Whatever You Want " was also worth watching. White Leaf had transmigrated from the original god to the grass god. He had the ability to be granted by the setting. He was invincible and cool. He had a grand worldview and a cyberpunk style. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

I recommend My 1995 Little Farm, by Lord Ye and Dragon A. This was a great novel about urban rebirth and farming. The protagonist, Chen Ling, brought the grotto-heaven back to 1995 and built a paradise. He raised chickens and ducks, played with dogs and herded cows, hunted when he was free, and farmed when he was busy to make money. Although he had a golden finger, it was not out of the ordinary. It was mainly for support. The writing style was daily, and the descriptions were exquisite and realistic. The hunting and dog training were written very well. However, the author's updates were slow. The first few chapters were a little torturous, but the later chapters were super exciting. There was no pretentious plot, just a plain farmer's life. Cute children and cute dogs were super interesting, and it was worth reading quietly. I would also like to recommend 'Unscientific Primitive Man'. The author has written thousands of books. This was a fictional historical novel. The main character Wang Wei had transmigrated to a primitive society, but this primitive society had subverted his three views. Primitive people were tall and powerful. Dinosaurs and giant insects were all from this era. The protagonist relied on modern knowledge to develop the tribe, and the system kept crashing. The theme of this book was quite creative, and the plot was a little naive. However, there were few bugs in the setting of the primitive era, and there were not too many fantasy settings. The primitive people were also very pragmatic. It was a good finished novel. There was also Super Grand Chieftain, written by Hemo. The main character, the stone bear, was a 1764 North American Indian boy. At that time, the North American continent was in chaos, and the European colonists did not dare to move west. This was Old Mo's first time writing a historical novel. He had written five books with more than ten million words and kept updating them, so he could collect them without worry. Even though there were no excellent works by a level four author, he could try investing in this book and see how the "Son of God" Shi Xiong led his people to write magnificent paintings. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some novels that involve the evolution of humans into the cosmic era: - "The Age of the Universe" was written by Zhtty. In the novel, humans head into the universe to roam the stars. There is a setting for cosmic adapters (New Humans NT). This can be seen as an evolutionary direction for humans in the age of the universe. After they leave the mother planet of reproduction, the race will randomly give birth to individuals that adapt to the universe. - "The Legend of Master Shi": In Fang Xiang's novel, the main character Ye Chong grew up on a trash planet. After acquiring a broken mech, he entered human society and continued to grow and struggle. The world view constructed in the novel was that humans were already living in the environment of interstellar society. Although there was no explicit mention of human evolution, the plot of human survival and development in such a cosmic environment also reflected the survival of humans in the cosmic era. - "Super Battleship of Rebirth": This novel was created by the Rainbow Gate. The protagonist, Xiao Yu, merged his soul into the AI to build a spaceship to escape after the Earth's Big Bang, and began his journey to the universe. This also showed the plot of mankind entering the universe when facing the disaster on Earth. It could also reflect the evolution and development of mankind in the era of the universe. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Human evolution originated from the forest apes, and gradually developed from primates through a long process. It mainly went through four stages: ape humans, primitive humans, intelligent humans, and modern humans. In the early stages of life, the first life forms on Earth were simple single-celled primordial cells of microorganisms. They only had simple genetic protein, but later evolved into more stable DNA. The primordial cells gradually evolved into specialized organelle and developed into complex microorganisms, which then formed eukaryota and laid the foundation for diverse life forms. The Dickenson jellyfish was the earliest known animal. Although it was simple and flat without a mouth and digestive system, it represented a rather complex multicellularized organism. Later, the earliest complex organ system began to appear. Fish were the first group of vertebrae. The evolution of bony fish brought about complex changes in the skeletal system and produced " primitive limbs ", allowing organisms to walk on land. The transformation from the ocean to the terrestrial environment was an important development in the evolution of life. These creatures became the ancestors of the quadruped, and the subsequent amputated animals, reptiles, birds, and mammals were their descendants. About 200 million years ago, the earliest mammals appeared. In the early days, they were small shrew-like creatures that coexisted with dinosaurs. Later, they evolved characteristics such as hair, specialized teeth, sweat glands, and a more efficient circulatory system. They also had unique characteristics such as night-walking, breast, and external genitalia. The first great apes appeared in Africa about 7 million years ago, such as orangutans, gorillas, and chimpanzees. They were highly intelligent and social. After that, an ape gave birth to the earliest Homo Evolutis species. The main developments during this period included the apes 'all-weather bipedal walking, the increase in brain size, the development of advanced bones that were conducive to making tools and hunting, the invention of fire and clothes in the early Homo Evolutis, and the subsequent evolution of complex language, hair loss, and dramatic facial changes. In the 20th century, most human scientists believed that the advancement of modern society's medical science, the effect of cell antibodies, and the improvement of diet had hindered human genetic evolution. However, in recent years, there were reports that the pressure of modern fast-paced life accelerated human evolution. In the process of human evolution, there was also a change from nomadic life to a settled life after the agricultural revolution. This change changed the way of human life and cultivated a more complex social structure. The emergence of writing and the industrial revolution were also important signs of development in the process of human evolution.
