How people have evolved, how people have evolved

Australopithecus --- early ape-man--- late ape-early sapiens - late sapiens - modern man.

It should be an ape. Early ape-man 2 million years ago to 1.75 million years ago Homo sapiens (Audwe Gorge, Tanzania) Brain volume 637 ml, walking upright, thumb and other four fingers can be held together, but the movements are not precise. Gravel can be beaten into choppers, and this stone tool culture is called the Auduvé culture.

Homo sapiens live in complete dependence on the natural world. Late ape man 1.75 million years ago to 20 300,000 years ago Yuanmou Man (Shangnabang Village, Yuanmou, Yunnan Province, China) Peking Man (Zhoukoudian, Fangshan District, Beijing, China) Javanese Man (West Java, Indonesia) With a brain size of 1 059 ml, he can walk upright on two legs like modern humans, and his hands are more flexible, and he can make a variety of stone tools. It can manufacture many types of stone tools, the processing is exquisite, the stone tool culture has made great progress, can use fire, live in a group of dozens of people, and have a certain ability to cope with natural changes.

Early Homo sapiens 20 300,000 years ago to 50,000 years ago Maba Man (Maba Township, Qujiang County, Guangdong, China) Neanderthal (Neanderthal Valley, Germany) The brain volume is 1 350 ml, which is close to the brain size of modern humans, and some original features are retained in the physique (protruding mouth, developed eyebrow ridge, etc.). Able to produce tools, able to hunt large beasts, master the technology of artificial fire, and the ability to conquer nature further.

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 process of human development, it is generally divided into four stages:

1. 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. This is a schematic diagram of human evolution, from the ** we can see that human beings from an ape, slowly learned to walk upright, and then had wisdom, began to know how to use tools, and then evolved into a real "human", but on the far right of the figure, it evolved into the form of an ape, becoming a "programmed ape".

For many people, this is the process of human evolution, of course, there is also a part of the spoof, it is not easy for humans to stand up and be human, but in the end they become ape form, which is somewhat ironic.

In addition, there is also a picture of human evolution that is also full of bad taste, when I first saw this picture, I really thought it was a little funny, apes evolved, desperately ate and finally evolved into pigs, obviously this is used to satirize those "foodies". But when we calm down and think about it, what is the meaning behind the creation of these bad tastes? In my opinion, this so-called "map of biological evolution" is misleading to people who do not know much about living things.

For example, in 1965, there was a diagram that showed the process of "early evolution" of human beings, called "The March of Progress". The author of this image is Rudolf Zalinger.

However, I feel that this picture still lacks evidence and is not sufficient, so I think that the map made by the American anthropologist Francis Clark Howell is more authoritative, because the miniatures above are all fossil models excavated after research, which can more intuitively understand the process of human evolution. But some of these fossils are not human fossils, but human paraphyletic fossils. But do you find it, when we look at this picture, we will find that everything is very smooth and complete, so what is wrong?

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 genetic DNA is evolutionary, confirming the authenticity of the theory of neutral evolution.

The evolution of man is divided into 4 stages, which are as follows:

1. Early ape-man, 2 million to 1.75 million years ago. Able to walk upright and resistant to ridge leakage, and can use the simplest stone tools;

2. Late ape-man, 1.75 million to 300,000 years ago. Specifically, there are earlier ape people such as Yuanmou Man and Peking Ape Man, who are more agile and flexible, know how to use fire, mainly live in groups, and can create more exquisite stone tools in the wild;

3. Early Homo sapiens, from 300,000 to 50,000 years ago, including Maba Man, Neanderthals, etc. Most of them are close to modern humans, but there are still a few ape-man characteristics, which can produce simple tools, hunt wild animals, and know how to make fire manually;

4. Late Homo sapiens, 50,000 to 10,000 years ago, including cave people and Cro-Magnon, etc., have a brain capacity comparable to that of modern humans, and their appearance characteristics and body are similar to those of modern humans, and can make more complex stone tools, horn tools, and rotten bone tools. Know how to make simple decorations, sew clothes, build tents, etc.

There are forest apes that evolved into modern apes and humans.

Homo sapiens (scientific name: Homo sapiens) is the only living species in the genus Homo. The morphological characteristics are more advanced than those of Homo erectus.

It is divided into early Homo sapiens and late Homo sapiens. Early Homo sapiens used to be called homin, lived 250,000 40,000 years ago, and was mainly characterized by a large brain volume, more than 1,300 ml; The brow crest is well developed, the forehead is sloping, the occipital region is prominent, the nose is wide and flattened, and the jaw is protruding. It is generally believed that Homo erectus evolved from Homo erectus, but it has been controversial [1] that Homo erectus became extinct after the later rise of Homo sapiens (modern humans) out of Africa or before that.

Late Homo sapiens (new humans) are anatomically modern humans. It began to appear about 450,000 years ago. The main morphological differences between the two are the reduction of the anterior teeth and face, the weakening of the brow ridge, and the increase in skull height, which is more pronounced in modern humans.

Late Homo sapiens arms were no more than knees, body hair was degenerated, there was language and labor, and there was a social and class character.

There are three types of materials to study the question of human beings: genes, fossils, and language and culture. Among them, the language and culture generally cannot exceed the Neolithic period. Many morphological features are not associated with phylogenetic differences.

Introduction: The oldest known fossil was formed in Ethiopia about 160,000 years ago. Homo sapiens in Europe appears to have replaced Neanderthals about 30,000 years ago. We don't know if this is a natural process.

The rest of the world is also gradually being occupied by Homo sapiens. They migrated to Asia and Australia at least at the same time as they appeared in Europe, but arrived in northeastern Asia much later. The New World was the latest, not earlier than 10,000,000 years ago.

Homo sapiens not only had new body structures, but also made more complex tools and kits, eventually developing Art Deco. In addition to the fossil record, there is a growing body of detailed evidence of technological and social behavioral developments in later periods [2].

Australopithecus - Homo sapiens - Homo erectus - Homo sapiens.

The evolution of man has been a thousand times. Little by little, it slowly forms.

Australopithecus - Australopithecus australopithecus - Homo homo sapiens - Homo erectus - Early Homo sapiens - Late Homo sapiens.

Paleoanthropological research has shown that many species of apes lived in the Old World 12 million years ago. The earliest fossil that can be identified as belonging to the evolutionary system of man is Australopithecus australopithecus, which lived 4 million 1 million years ago.

Human beings evolved from the ape system, and their emergence and development is a long historical process. Paleoanthropological research has shown that many species of apes lived in the Old World 12 million years ago. But the question of which of these are the direct ancestors of man, where and when the evolutionary process from ape to man began, is still far from being solved.
