The first human civilization was born many years ago 10 years ago

Direct evidence for the study of human origins comes from fossils. Anthropologists use comparative anatomy to study various fossils of Australopithecus and humans.

Determine their relative and absolute ages to determine the age of human fossils, and roughly divide the evolutionary history of humans into several stages. Geneticists use biochemical and molecular biology methods to study the size and rate of mutation of proteins and deoxyribonucleic acid (DNA) between modern humans, various apes and other higher primates to calculate their respective origins and differentiation ages. 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.

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. Capable.

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.

The first Homo hoans existed 1.9 million years ago. Homo habilis is classified under the family Homo homo. Homo 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.

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. Homo erectus fossils were first discovered in 1891 in Java, Indonesia.

At that time, there was also a debate about whether it was a man or an ape. It was not until the 20s of the 20th century that the fossils and stone tools of Peking Man were discovered in Zhoukoudian, Beijing, which established the position of Homo erectus in the history of human evolution. Homo erectus lived from about 1.7 million years ago to more than 200,000 years ago.

To date, Homo erectus fossils have been found in Asia, Africa and Europe. (4) Homo sapiens stage. Homo sapiens is generally divided into early Homo sapiens (ancient Homo sapiens) and late Homo sapiens (modern humans).

Early Homo sapiens lived between 200,000 and more than 100,000 years ago. Late Homo sapiens began about 100,000 years ago. Its anatomy has been basically similar to that of modern humans, so it is also called modern humans in anatomical structure.

Homo sapiens. Based on the fossil evidence of humans that has been found so far, Australopithecus is the earliest known human.

Human footprints on trilobite fossils, architectural ensembles on the ocean floor, human drawings with dinosaurs, etc., etc., are all at least between 5000 and 4000 BC, the Sumerian civilization in the Two Rivers Valley, approx. ,

According to current research, the earliest humans originated about 7 million years ago.

From the perspective of paleoanthropology alone, the current generally accepted timeline of human origins is:

Chadian Shah Man appeared about 7 million years ago, Protohomini appeared about 6 million years ago, Ape terracus appeared about 5.8 million years ago, Australopithecus appeared about 4.2 million years ago, Homo homo sapiens appeared about 2.5 million years ago, Homo erectus evolved about 1.8 million years ago, and Homo sapiens appeared about 200,000 years ago.

The earliest recorded history of civilization is ancient Babylon: between 4000 BC and 2250 BC.

Next up is Ancient Egypt.

3500 BC.

Ancient Greece: between 3000 BC and 1100 BC.

Ancient India: 2000 BC.

Ancient China. In 1600 BC, the Shang Dynasty was established (which is recognized as the history of China in world history).

There were five civilizations in the first civilization of mankind, and these five civilizations were in order from west to east, and the most westernmost side was a Crete island on the Mediterranean Sea, a civilization on the island of Crete, which we generally call it Cretan civilization. And then a little bit south on this side, a little bit to the south, that is, in North Africa, there was an ancient Egyptian civilization in Egypt. And then a little further east, on the west bank, in the valley of the two rivers, an alluvial land between the Euphrates and the Tigris, and in this place there was a civilization of two rivers, or it was generally called the Mesopotamian civilization, or we called it Sumerian in the form of its original state, and we called it Sumer.

Further east, there is one of the oldest civilizations in the Indus Valley, the civilization of the Indus Valley, called the Harappan civilization. Then further east, of course, is our Chinese civilization in the Yellow River Basin, generally we refer to the Xia and Shang dynasties. Further east, there is actually a highly developed civilization in South America, the Mayan civilization, which is now prevalent.
