How did the first man come into being in the history of mankind?

<> chimpanzees, the closest living apes to humans.

In fact, the first person does not exist at all. If we take the individual as a unit, each generation is different for the sexual reproductive species, the heredity and variation are very random, and the offspring may or may not be very similar to the parents, and there is no way to talk about evolution.

True evolution is in populations. Although natural selection works on individuals, evolution occurs at the population level. The sum of the effects of natural selection on individuals constitutes the direction of evolution of the population.

A species is simply a group of animals that can freely exchange genes. After a population reproduces one generation, the changes in the gene pool are negligible, and the population remains the same population. More than a decade later, under the action of natural selection, the gene pool of the population has undergone certain changes.

And thousands to tens of thousands of generations later, due to the accumulation of changes, the gene pool of the population has become very different from that of the ancestors, and a new species is born.

Therefore, there can be no first people, only the first group.

<> when a group of predecessors (possibly a species of australopithecus) had their brains enlarged and learned to make tools, the transition from humans to humans was completed. True man, meaning real human being, that is, human is an animal, which is the narrowest definition of human beings, and all of them are indisputable "people" in this category. According to brain volume and skull morphology, human beings are divided into three evolutionary stages: Homo sapiens, Homo erectus, and Homo sapiens.

Homo sapiens is anatomically modern man.

However, evolution is a gradual process. Even the evolutionary event of rapid change cannot be completed in a few generations, and the transition from ape to man, predecessor to human and between different human races may require the accumulation of tens of thousands of generations, which is indeed only a moment relative to geological time, which can be called rapid change, but it is also very long relative to the life span of human individuals.

The transition from apes to humans, i.e., the creation of upright walking, we only know that it occurred about 5 million years ago, but we have not been able to find a definite generation. It is obviously absurd that no matter which generation we divide humans and apes from, there will be a situation where parents and children belong to different species. Similarly, the transition from humans to humans occurred more than 2 million years ago, and Homo sapiens appeared more than 300,000 years ago.

Since evolution was gradual, classification was subjective, and the first group of humans did not actually exist, we can only roughly know when apes became humans.

I prefer to evolve, and as the apes adapted to life on earth, their descendants moved closer to modern humans from generation to generation, until finally they completely lost the symbol of the ape and became a true man.

For human beings, we would love to find out who the first man was, and for this reason we have imagined many mythological stories, such as: Adam and Eve in Western mythology; Fuxi and Nuwa in Oriental stories.

But in nature, the first man did not actually exist, because in the process of biological evolution, the boundary between man and ape was not so clear, but there was still genetic exchange.

The earliest hominants currently have the answer, and that is "Lucy Maiden". In 1974, American scientist Donald Johnson discovered an ancient hominin fossil specimen at the bottom of the Afar Valley in Ethiopia, which was identified as a hominin who lived 3.2 million years ago. Because the fossil was female, scientists named it "Lucy Maiden".

The first person in the world was a Lucy girl. Lucy is the name of an hominin fossil of Australopithecus afarensis discovered in Ethiopia in 1974, Lucy lived 3.2 million years ago, so it is believed to be the first human to walk upright and the earliest known ancestor of humans.

Lucy's characteristics

On November 24, 1974, American paleoanthropologists Donald Johnson, Yves Cobens, and Tim White discovered a fossil of a bony human in the Afar Depression in Ethiopia.

It was Lucy Maiden, and later, archaeologists discovered her fossils!

Adam.

When there were no human beings in the world, God was not used to seeing the desolation of the world, so he created the first man in the world, Adam, after Adam came to this world, he felt that he was the only one in heaven and earth, and he could not find a confidant, and he was very bored, so he pleaded with God and asked God to have a companion for him.

God agreed, one day, God sent someone to take Adam while he was asleep, took a rib from him, and created the world's first woman, Eve, Adam woke up and found that there was one more person around him, and felt very happy, and from then on, Adam and Eve lived carefree in the Garden of Eden, multiplying the next generation, and bringing prosperity to the world.

Therefore, the first human in the legend of Asia at that time, but the legend is a legend after all, according to the discovery of archaeologists, the earliest human in Asia should be Wushan people, for the topic of the earliest human beings, different countries have different statements, different discoveries, so far can not have a definite answer.

But if you can distinguish who the first person is, it is completely impossible, the unit of species evolution is not an individual, but a population, the change of a single individual will not give birth to a new species, species evolution requires the accumulation of genetic mutations of the entire population, and the whole process is gradual, not a mutation, yesterday or the ancient ape today directly became human.

After Australopithecus, humans went out of the African continent for the first time, and their footprints spread to most parts of the world, and because of the different living environments, different human races were eventually born, such as Neanderthals.

And the groups that did not leave the continent continued to evolve, and eventually Homo sapiens appeared, and Homo sapiens is considered the direct ancestor of modern humans. But if it is the first Homo sapiens, it cannot be found, it can only be a group of people.

This is true of any species, the basis of evolution is the accumulation of genetic variation in a group, and then selected by nature, so the first person does not exist, and there will not be such a clear point in time on the road of evolution, and the whole development and evolution is a long process of gradual change rather than mutation.

The first human being:

The earliest humans found in the world were Australopithecus, which lived between 5.5 million and 1.3 million years ago. The age of life is about 1.7 million years ago, and the difference is no more than 100,000 years before and after (some scholars believe that the age should not exceed 730,000 years, that is, it may be 600,000 to 500,000 years ago or later).

The earliest fossil of Australopithecus was discovered in 1924. At that time, Dart, an Australian, traveled to South Africa to work as a professor of anatomy at a university in Johannesburg.

He is very interested in fossils and often encourages his students to look for them outside of school. He also told the quarry owner to tell him if he found fossils.

The stages of human evolution:

1. Australopithecus stage. Australopithecus australopithecus has been found to have lived between 4.4 million and 1 million years ago. According to the study of the anatomical features of fossils, the most important feature of Australopithecus that distinguishes it from apes is its ability to walk upright on two legs.

2. Capable stage. First 2 million First 1.75 million years Homo sapiens fossils were discovered in Tanzania and Kenya in East Africa since 1960.

The earliest Homo habilis existed 1.9 million years ago, and homo habilis was classified under the family HomoHomo sapiens had significantly larger brains than Australopithecus australopithecus, and could use stones as materials to make tools (stone tools), which gradually evolved into Homo erectus.

Why do I think it might be Pangu? It could also be Lucy, it could be Adam, and the youngest could be Australopithecus.

The first human being:LucyGirlish. From archaeology.

The words spoken are Lucy. The oldest human fossil found so far, named Lucy, was found in Africa, and this fossil is also believed to be a human grandmother Lucy was found in East Africa.

Fossil specimens of hominin. Lucy lived about 3.2 million years ago and was classified as a homini, and the skeleton has ape-like brain capacity and human-like bipedal upright walking, supporting the idea that upright walking precedes brain capacity in the evolutionary debate for humans.

The reason why Lucy is identified as an ancient human.

More than 12 million years ago, forest apes were widely distributed in Africa, Asia and Europe, especially in the tropical jungles of Africa.

Mainly arboreal life, the other branch slowly evolved into humans due to environmental changes, which shows that humans and apes are the closest relatives, and they have a common primitive ancestor is the forest ape. The Anthropo-Apes Dividing Line.

Whether it is possible to walk upright, according to archaeological finds, Lucy's pelvis.

The hip bone is broader, and the femur of the lower limb bone is thicker.

These characteristics all indicate that Lucy can walk upright, and also indicate that Lucy belongs to ancient humans and not great apes, so the answer is, forest australopithecus, walking upright.

Capable.

The earliest members of the genus Homo generally refer to humans before Homo erectus, first of all, "Homo sapiens". Homo sapiens lived about 1.8 million years ago. Homo sapiens fossils were first discovered in the Oduvai Gorge in Tanzania since 1960.

In 1972, more than 150 fragments of a skull, dated 2.9 million years ago, were found in Kupifra, on the eastern shore of Lake Turkana in Kenya, East Africa. Since this skull does not have a protruding but connected brow ridge, its position in the evolutionary system is still controversial.

The physique of early Homo sapiens was close to that of modern humans, with a brain volume of 1300-1750 ml, but it still retained some primitive features, such as a well-developed brow ridge, a low and slanted forehead, a flat and wide nose, a protruding jaw, and an inconspicuous chin. It is believed that early Homo sapiens evolved from Homo erectus.

Pekingese:

In 1929, in the cave on the Dragon Bone Mountain in Zhoukoudian, Beijing, the ruins were stacked more than 40 meters thick. This site was the first to be discovered in 1921 by Chinese archaeologists a complete fossil of an ancient human skull, which is the world-famous Peking Man.

They lived between 700,000 and 200,000 years ago, and still retained some of the characteristics of apes, but they had a clear division of hands and feet, could make and use tools, and used natural fire. The forests are dense, overgrown with wild grasses, and infested with wild beasts. The Pekingese beat stones into rough stone tools and cut branches into wooden sticks, waging a tough struggle against nature with the most primitive tools.

In such a hostile environment, it is impossible to live on the strength of a single person. Therefore, they often have dozens of people together, work together, share the fruits of labor together, and live in groups. This led to the formation of early primitive societies.
