What is a person? Why would anyone? How are people formed?

The Origin of Life At the beginning of the formation of the earth, due to various physical and chemical reactions, the earth was in an extremely hot state, and there could be no life there. Later, as the Earth slowly cooled and its unique astronomical location and structure, life quietly evolved. Since ancient times, people have been concerned about the origin of life, and various hypotheses have emerged.

Today, except for the unresolved problem of the hereditary, the general outline of the process has gradually become clear. Creationism holds that life was created by a supermaterial God, or a transcendental transcendental determinism. It is a primitive idea that arose from the low level of human understanding of nature, and was later exploited by socialized ideologies, either consciously or unconsciously, to lead those who believe in the absolute supremacy of the spirit to believe in creationism.

The Theory of Absence of Origin In ancient times, people had a low ability to understand nature, but they were able to carry out abstract thinking activities, and made conclusions that life occurs naturally according to phenomena, and its representative ideas include ancient China's "flesh saprophytes grow maggots, fish wither and beetles" and Aristotle's "some fish develop from silt and gravel". With the deepening of understanding, people knew that maggots came from flies, and after Pasteur, it was believed that life was produced by parents and spores, that is, life could not arise naturally. But the theory of origin does not have how the first life was formed.

With the great development of astronomy, people put forward the "embryo" of life on the earth and other planets or the universe, and this understanding was popular in the 19th century, and there are still very few people who adhere to this view, based on the fact that all organisms on the earth have a unified genetic code and the rare element molybdenum has a special important role in the enzyme system. The theory of chemical evolution advocates the study of the origin of life from the law of motion and change of matter. It is believed that under the conditions of the primitive earth, inorganic matter can be transformed into organic matter, and organic matter can develop into biological macromolecules and multimolecular systems until the emergence of primitive life forms at the end.

This view was first put forward by the Soviet scholar Oparin in 1924; Five years later, the British scholar Haldane made a similar view. They all believe that life on Earth has evolved over a long period of time from non-living matter; This process is called chemical evolution, as distinct from biological evolution after the emergence of living organisms. Oparin's book The Origin of Life on Earth, published in 1936, was the world's first monograph to comprehensively address the question of the origin of life.

He believes that the reductive atmosphere without free oxygen on the primitive earth can generate simple organic matter (biological small molecules) under the action of energy sources such as short-wave ultraviolet rays, and simple organic matter can form complex organic matter (biological macromolecules) and form aggregates of multimolecular systems in the primitive ocean, the latter after a long period of evolution and "natural selection", and finally the emergence of primitive life, that is, protozoes. Experimental evidence for chemical evolution is growing and is accepted by the vast majority of scientists.

The term human, or human, can be defined in terms of biological, spiritual, and cultural dimensions, or a combination of these definitions. Biologically, humans are classified into the general kingdom eukaryotic kingdom Animalia Metazoan subkingdom Posterior Mouth Animals Chordate phylum Vertebrate Subphylum Amniotic Materia Mammalia Euzoan suborder Primate Anthropoid suborder Narrow-nosed monkey suborder Homo superfamily Homo subfamily Homo subfamily Homo sapiens species, but most of the latter are not unanimously recognized by the academic community), also known as higher animals, with highly developed brains. On a spiritual level, man is described as being able to use the concept of a variety of souls that are believed to be associated with divine power or presence in religion; In mythology, the human soul is also compared to other humanoids.

In cultural anthropology, human beings are defined as those who are able to use language, have complex social organizations and technological developments, and above all are able to establish groups and institutions to support and assist each other.

There are two theories about the origin of humanity:

1. Forest Australopithecus.

Forest Australopithecus branched out into several branches, such as Giant Ape, Siva Australopithecus and Rama Australopithecus. Rama australopithecus lived about 14 million 7 million years ago, and the earliest fossil is a fragment of the right maxillary found by the American scholar Lewis in the Sivalik Mountains of North India in 1932, which has several human features.

After the 60s, similar fossils were found in Tenamburg in Kenya, Rudabania in Hungary, Pyrgos in Greece, Cheadle in Turkey, Bodwar Plateau in Pakistan and Lufeng in Yunnan Province in China, and their common characteristics are: snout shortening, tooth arch opening backward, teeth closely arranged, small canine teeth, wide and short crown of buccal teeth, and the first premolar of the mandibular is bicuspid and thick enamel.

2. Australopithecus.

At present, it is generally believed that the time when Australopithecus transformed into the first human ancestor was 7 million years ago. Judging from the human fossils that have been discovered, the evolution of human beings can be roughly divided into the following four stages:

1) Australopithecus stage. Australopithecus australopithecus has been found to have lived between 4.4 million and 1 million years ago.

2) Capable person stage. 2,000,000 BC-1,750,000 BC. Homo sapiens fossils have been discovered in Tanzania and Kenya in East Africa since 1960.

3) Homo erectus stage. Homo erectus belongs to the homo genus homo erectus (homo erectus), referred to as Homo erectus, commonly known as ape-man.

4) Homo sapiens stage. Homo sapiens is generally divided into early Homo sapiens (ancient Homo sapiens) and late Homo sapiens (modern humans). Based on the fossil evidence of humans found so far, Australopithecus is the earliest known human.

Anthropomorphic reasoning, labor allows apes to evolve to stand and go to the land.

1. The transition from ape to man:

If you count from Ramaucos, about 10 million years have passed; If we count from Australopithecus, there are 200,300,000,000 years. In the process of using natural tools for a long time, creatures in the transition period finally learned to make tools. The manufacture of tools is a conscious activity, and this conscious agency is the most important characteristic that distinguishes humans from animals, and it marks the end of the transition stage from apes to humans.

2. After the end of the transition from ape to man:

The human physique continues to develop. Over a long period of time, people divided this development process into three stages: ape-man, ancient, and new-man.

1. It is divided into three stages: Australopithecus, Homo erectus, and Homo sapiens; Homo sapiens is further divided into early Homo sapiens and modern Homo sapiens. The disadvantage of this division is that it puts Australopithecus australopithecus who cannot make tools and Homo 1470 who can make tools in the same category.

2. It is divided into three stages: the earliest human beings (or the earliest human genus): Homo erectus, early Homo sapiens, and modern Homo sapiens. Chinese scholars have also proposed four stages of division, namely early ape-man, late ape-man (Homo erectus), early Homo sapiens, and late Homo sapiens.

1. Refer to the Tree of Evolution of Life - see how animals evolve.

2. Refer to the human evolution map - see how the ancient apes evolved into modern humans.

Man is made of water and carbon!!

What you're asking is: How did humans come to be on Earth? Or how did a person come into this world?

Most of them are caused by these behaviors such as criticism, accusation, complaining, and comparison from parents in the original family when they were children.

Legend has it that the man was made of mud by Nuwa Niangniang.

Hello, in fact, humans evolved from ancient apes.
