How did humans come into being? How humans came into being

How did humans emerge and develop?

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.

Evolved from humanoid Yuan.

Human beings evolved gradually from genetic mutations produced by living organisms.

Scientists say humans evolved from a prehistoric shark that roamed the oceans more than 300 million years ago. According to the latest research, this primitive fish, called the genus Acanthus, is the common ancestor of all jawed vertebrates on Earth, including humans. Based on the fossil material of Australopithecus and hominin that has been discovered, the earliest humans may have appeared 3 million or 4 million years ago.

The first humans were born out of "genetic variation of a new species". Modern humans are the result of the continuous optimization of "genetic variation of the same species" after a new species.

The Six Stages of Human Evolution:

1. Rama ape stage.

Humans in the Rama ape stage have just evolved, and from the outside, there is no essential difference from apes, but the digestive system has undergone qualitative changes, which is the initial state of ape evolution to humans.

Second, the Australopithecus stage.

After reaching the stage of Australopithecus, humans can already walk on their feet, their hands have been completely freed and can be used for related labor activities, and humans at that time can also use simple gestures to communicate verbally to convey information.

Third, the stage of capable people.

Human beings in the stage of capable people mainly have a significant increase in IQ, and the IQ of animals is fundamentally comparable to the IQ of humans, however, the breakthrough of human IQ is also manifested in the stage of capable people, and human beings in the stage of capable people can carry out basic arithmetic activities, and can also keenly reflect what is happening around them.

Fourth, the non-subape-man stage.

5. The Ancient Stage of Europe.

Human beings in the ancient stage of Europe mainly had great changes in their thinking, human beings have begun to be able to be self-sufficient, build their own houses, farm land for corresponding labor activities, etc., and in this stage, the spiritual culture of human beings has also been significantly improved, and tombs have begun to appear in this stage.

6. Homo sapiens stage.

The Homo sapiens stage is the last stage of evolution to modern humans, the human beings in the Homo sapiens stage are almost similar to modern humans, with a very high IQ, when humans reach the Homo sapiens stage, they have a huge improvement in physical and mental strength, and begin to learn to use stratagem to achieve their goals.

The Earth has survived for 4.6 billion years. Humans were born 5 million years ago.

That is to say, 60 million years after the extinction of the dinosaurs, human beings were born, and humans were differentiated from the animal kingdom, and taxonomically, homo sapiens belong to the subphylum Vertebrates, Mammalia, Primates, Anthropoids, and Homo.

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.

Human is an umbrella term for human beings. Biologically, humans are classified into the general kingdom eukaryotic kingdom Eukaryotic subkingdom Zoological kingdom Posterior Mouth Animals Total phylum Chordates Vertebrate subphylum Amniotic general order Mammalian subclass Euzoomia subclass Primate ape suborder Narrow-nosed monkey suborder Homo sapiens subfamily.

Human beings can be defined on biological, spiritual, and cultural levels, or a combination of these definitions. Biologically, man is classified as a hominida, homin, hominid, a higher animal. On a spiritual level, man is described as being able to use the concept of a variety of souls that are believed in religion to be associated with divine power or spiritual immortality.

People:"Able to manufacture delicate tools, and be able to skillfully use tools for labor, have rich thinking ability, have the ability to judge that there is no conflict with the actual situation and conflict with the actual situation, have the ability to initially maintain the earth's ecosystem, have the ability to create and control the restoration"People should live in harmony with each other, and trust and communication are the most basic ways of survival between people.

Evolutionary studies suggest that humans originated from forest apes and evolved step by step from primates through a long evolutionary process. DNA and fossils prove that humans originated in Africa about 3 million years ago.

Compared to other animals, humans have highly developed brains, complex abstract thinking, language, self-awareness, and problem-solving skills.

The erect body structure of the human body allowed the human forelimbs to move freely, which allowed the intelligent human to master the use of tools far beyond that of any other species, and eventually developed great labor ability and creativity. Man is a higher social animal.

Summary. Human beings originated from forest apes, and went through four stages: ape humans, primitive humans, 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 social life in groups, which is very conducive to cooperative prey, food gathering, and information exchange, thus giving Homo sapiens an advantage in the competition for survival.

How the hell did humans come into being.

Human beings originated from forest apes, and went through four stages: ape humans, primitive humans, 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 social life in groups, which is very conducive to cooperative prey, food gathering, and information exchange, thus giving Homo sapiens an advantage in the competition for survival.

Theoretically, the process of human origin is divided into three stages: the stage of Australopithecus, the stage of man and ape, and the stage of man who can make tools, and the later stage includes the two major periods of ape and Homo sapiens, which are divided into two stages: early and late. Darwin's theory of evolution proves that human beings evolved from ancient apes, but there is a loophole in this, because Darwin's theory of evolution also proves that the evolution process of a creature takes tens of millions of years, and the time for human beings to appear is only a few million years, which is shorter than the dinosaurs.
