Humans are the product of evolution, and 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.

Predecessors 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.
About 4.5 million years ago, humans and apes began to diverge, giving rise to Australopithecus ramanacus, which later evolved from Australopithecus australopithecus 2 million years ago, and then further developed into modern humans. Regarding the development process of human beings, it is generally divided into four stages: 1. The early ape-man stage.
It lived between 3 million and 1.5 million years ago, and already possessed the basic characteristics of humans, such as being able to walk upright and make simple gravel tools. 2. Late ape-man stage. About 2 million to 300,000 years ago, the body resembled a man, the brain was larger, and it could make more advanced paleolithic tools, and began to use fire, such as the Beijing ape man in Zhoukoudian, Beijing, China.
3. Early Homo sapiens (hominid) stage. Between 100,000 and 200,000 to 50,000 years ago, it gradually broke away from the characteristics of apes and was very close to modern humans, such as Neanderthals in Germany. 4. Late Homo sapiens (newcomer) stage.
About 4-50,000 years ago, the evolution of human beings at this time showed a significant acceleration, and the morphology was very similar to that of modern humans, and culturally, there were already the art of carving and painting, and ornaments appeared. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered. At this time, primitive religions had already arisen and had entered a matriarchal society.
In the late Homo sapiens stage, modern humans began to differentiate and form, and spread throughout the world.

I heard that man evolved from pigs!

Humans are, of course, animals.
And it's a high-level animal.
First of all, evolution is a long process, in the case of humans. It took nearly 25 million years to evolve from apes to upright walkers, from ape-humans to humans.
Second, it's clear that you have a misconception of evolution. Although human beings are currently at the top of the food chain on the planet, this does not mean that human beings are the end of evolution or the only way to go. Humanity still has a lot of imperfections.

Human evolution originated from forest apes, and developed step by step from primates through a long evolutionary process. It has gone through four stages: ape man, primitive man, sapiens man, and modern man.
Due to the development of archaeology, prehistoric civilization has been gradually denied, and archaeology has most of the evolved hominin fossils. In conjunction with the discoveries of modern biology, it was discovered that the DNA of inherited genes[1] is evolutionary, confirming the authenticity of the theory of neutral evolution. [

Humans evolved from apes.

Forest Australopithecus. Humans evolved from forest apes. Forest apes are a group of fossil apes with a large and diverse species.
The fossils were found in Miocene and Pliocene strata over a vast area of Asia, Europe and Africa, and lived more than 12 million years ago. They are humans and apes.
of the common ancestor. Forest Australopithecus has a short body and a rib cage.
Broadly flattened, the forearms are as long as the legs. The forelimbs are both walking crutches and organs used to hang and swing through the jungle and pick wild fruits. They're like chimpanzees.
Live a group life like that. Due to the massive disappearance of forests, a large number of forest australopithecus had to go down to the ground. Long periods of walking on the ground have led them to evolve to walk upright.

Australopithecus. The evolutionary process of human beings can be divided into four stages:
1) Early ape-man stage: lived about 3 million to 1.5 million years ago, and already had the basic characteristics of humans, able to walk upright, and make simple gravel tools.
2) Late ape-man stage: about 2 million to 300,000 years ago, the body is like a man, the brain is larger, can make more advanced paleolithic tools, and began to use fire, such as the Peking ape man in Zhoukoudian, Beijing, China.
3) Early Homo sapiens (hominal) stage: 10-200,000 to 50,000 years ago, gradually detached from the characteristics of apes and very close to modern humans, such as Neanderthals in Germany.
4) Late Homo sapiens (new man) stage: About 4-50,000 years ago, the evolution of human beings at this time showed a significant acceleration, and they were very similar to modern humans in form, and culturally, there were already the art of carving and painting, and ornaments appeared. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered.
Give me points.
Humans evolved from Australopithecus.
Why do people live? There are many answers. Here's how I understand it: >>>More
Composition of a computer A computer is made up of two parts: hardware and software. Hardware On the outside, a computer is made up of a host, a monitor, a keyboard, a mouse, and a speaker. In terms of function, the hardware of the computer mainly includes the processor, memory, input device, output device, etc. >>>More
It is likely that black holes also evolved from stars, and when a star ages, its thermonuclear reactions have exhausted the fuel (hydrogen) at the center, and the energy produced from the center is running out. In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse until it finally forms a small, dense star that regains its ability to balance with the pressure. >>>More
There are also single-celled lower animals like snakes, earthworms, and paramecium, like protozoa. >>>More
