The origin of man, the origin and development of man

Human beings evolved from Australopithecus, and the origin and development of human beings, that is, the process of evolution, is: Ramapicus, Australopithecus, early Homo erectus, (late) Homo erectus, early Homo sapiens, late Homo sapiens, and modern man. Modern humans belong to Late Homo sapiens in human taxonomy and are a subspecies of Homo sapiens.

Homo sapiens is a general term for man, generally referring to Homo sapiens, and is the only extant species of the genus Homo sapiens in the biological classification.

Humans are mainly concentrated in urban centers, thanks to their ability to adapt and modify habitats using technology.

Human beings evolved from Homo erectus, and modern humans and Homo sapiens belong to the same species, and the development and complexity of the brain are conducive to the social life of clusters.

On June 6, 2013, the top international academic journal "Nature** published the results of Ni Xijun, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, and others, who analyzed a series of morphological characteristics of one of the oldest primate fossils after 10 years of research, thus proving that apes originated about 55 million years ago. Previously, the earliest ape fossils discovered by the scientific community came from 45 million years ago, and this achievement pushed the history of human ancestors by 10 million years, which can be called a milestone in the history of primate and paleohuman research.

The evolutionary process of human beings can be divided into four stages: (1) the early ape-man stage: it lived about 3 million to 1.5 million years ago, and already had the basic characteristics of human beings, 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 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 (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 (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.

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.

The origin and development of human beings is a very complex issue, and although Darwin and others have worked hard to excavate and study it for more than 100 years, there are still different opinions and questions. Extended Material: After the transition from ape to man ended, the human physique continued to develop.

Over a long period of time, people divided this development process into three stages: ape-man, ancient, and new-man. Due to the continuous enrichment of fossil materials and the deepening of people's understanding, this staging method is no longer suitable. There are two main staging methods used by foreign scholars.

First, 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. The other is divided into 4 stages: the earliest humans (or the earliest genus Homo), 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. The "early ape-man" stage is equivalent to the "earliest human (genus)" stage proposed by foreign scholars. Although not many pre-Homo erectus fossil materials have been found, it is still appropriate to list it as a separate stage to distinguish it from Australopithecus and Homo erectus.

1.Darwin's theory of biological evolution holds that humans are the product of biological evolution, and that modern humans and modern apes share a common ancestor.

2.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.

3.Theoretically, the process of human origin is divided into three stages: the Australopithecus stage.

4.Also man and ape stage.

5.The stage of a person who can make tools.

6.The latter stage includes the two major periods of ape and Homo sapiens.

7.They are further divided into two stages, early and late.

8.After the transition from ape to man ended, the institutional form of human beings was still developing.

9.Scholars at home and abroad mainly use two periodization methods for this development process.

10.First, it is divided into three stages: Australopithecus, Homo erectus, and Homo sapiens, and Homo sapiens is divided into early Homo sapiens and late Homo sapiens.

11.The other is to distinguish the early humans who were able to make tools from the Australopithecus australopithecus who could not make tools, and list them as a separate stage, called the earliest Hominis, and the subsequent stages are divided into Homo erectus, early Homo sapiens, and late Homo sapiens.

12.Compared with the two, the latter is more appropriate.

13.The earliest members of the genus Homo generally refer to human beings before Homo erectus, the first being "Homo sapiens".

14.Homo sapiens lived about 1.8 million years ago.

15.Homo sapiens fossils were first discovered in the Oduvai Gorge in Tanzania since 1960.
