Man originally evolved from apes, and in the past, due to the climate change on the earth, apes had to go to the ground to stand upright in search of food, so Engels said that "labor created man". And because of the emergence of fire, human development has taken a big step forward, and it is possible to eat cooked food, keep warm, drive away predators, and so on. After millions of years, man changed from ape.
The ancestors of humans were apes. Apes began to emerge in the Oligocene, about 30 million years ago. However, not all apes are direct ancestors of humans, and some apes are human"Uncle", some apes are human"Uncle"。
The apes, which anthropologists consider to be the ancestors of humans, appeared very late. It is the Rama ape, named after one of the heroic princes of the ancient Indian epics, Rama (Rama's translation is now unified as Rama). They lived about 10 million to 15 million years ago.
Rama apes were first discovered in Mount Sivalik, India, Pakistan. In the late 60s of this century, Rudaaucus found in the Early Eocene coal seams of Hungary also belonged to Rama ape. In particular, a fairly complete mandible fossil of the Rama ape type found in the limeba coal kiln in Lufeng County, Yunnan Province, China in 1976 is the most complete and closest to the early ancestor of humans of the same kind found in the world.
The time is also more than 10 million years ago. According to the excavations, the body of Lufeng Australopithecus is the size of a chimpanzee, with a short snout and underdeveloped canine teeth, which is not commonly used by ordinary apes"**"。However, their intelligence is slightly higher than that of other animals, which, combined with their frequent activities in the open ground, prompts them to further divide their hands and feet.
Therefore, it is believed that Lufeng Australopithecus was able to grasp branches or other natural objects with their hands for defense and feeding. In this case, the hands have been divided, and the legs should be able to stand upright.

How did humans come into being? This question has been pondered by human beings since the beginning of human beings, and the fact that you can ask such a question today shows that your thinking has a deep consideration. In fact, in ancient times and ancient times, creationism has always occupied a very important position, in China there is Nuwa cut the earth to create people and Pangu to open the world, in the West God made God create all things in the universe in seven days, and on the sixth day created Adam and Eve.
This argument continued for a long time until modern times, when the theory of cells in the natural sciences, especially biology, was established in the West, and at the same time, some people put forward the idea of evolution. The culmination of the idea of biological evolution is Darwin's 1859 ".The Origin of Species proposed that man was evolved, and he wrote "The Origin of Man" in 1871, from which people know that as early as 4.6 billion years ago, there were very simple cells that lived in the sea, and after many years of evolution, apes on the East African plateau began to appear, and man evolved from ape-man.

There are many stories about the origin of mankind in the legends: Nuwa in China and God in the West, ......
At present, the more scientific view is Darwin's view, Darwin's theory of biological evolution is that man evolved from ancient apes. Due to the changes in the natural environment, the ancient apes that originally lived in the trees were forced to live in the ground, and in this process, people gradually learned to walk upright, and began to work, learned to use labor tools, labor promoted the formation of language, brain development, and the ability to make and use stone tools is a sign of human formation.

Don't know what you believe in? If you believe in evolution, then man is an ape. Personally, I believe that man was formed by a fluctuating phenomenon in the universe.
But they are still a bit of a rule, that is, in a period of time, human beings will be taller, their wisdom will be higher, and their society will be stable. For a period of time, the height will be lower, and the merchants will be a little higher, but the society is very chaotic. This is more or less the case in many world legends and religions.

Human beings originated from forest apes, and went through four stages: ape humans, proto-hominins, homo sapiens, and modern humans, and developed step by step from primates through a long evolutionary process. After the transition from ape to man ended, the institutional form of human beings was still developing.
Humans evolved from Homo erectus with a larger brain capacity, and modern humans and Homo sapiens belong to the same species. The development and complexity of the brain may be conducive to the social life of groups, which is very conducive to obtaining prey, gathering food, and exchanging information in a cooperative way, thus giving Homo sapiens an advantage in the competition for survival.
The Birth and Development of Mankind: Humans were born 5 million years ago. That is to say, 60 million years after the extinction of the dinosaurs, human beings were born Human beings are differentiated from the animal kingdom, and taxonomically, homo sapiens belongs to the subphylum Vertebrates, Mammalia, Primates, Anthropoids, and Hominis. >>>More
How did humans emerge and develop?
In the early days, there were many substances such as methane, nitrogen dioxide, etc. on Earth. Amino acids are formed under the action of lightning, and then through a series of chemical changes (such as polycondensation reaction, etc.), proteins with life activity are generated, and this is the origin of life. The earliest organisms were unicellular and lived in water (but the sun's ultraviolet rays irradiated the earth very strongly). >>>More
In general, the origin of human beings.
Scientifically theoretically inclined to choose the theory of evolution. >>>More
Humans evolved from Australopithecus, and the real appearance of humans actually began between 8 million and 4 million years ago.
