How many years has humanity been in history? How many years is there in human history?

The world's earliest ape-man fossil was discovered in 1891 on the Indonesian island of Java, dating back 60 to 800,000 years. The Javanese ape-man, together with the Peking man discovered in Zhoukoudian, China, in 1927, was once recognized as the "earliest" human in the world. At that time, it was believed that the history of mankind was no more than 100,000 years old, and the first human beings appeared in Asia.

The Shandong Yiyuan ape man, discovered in China in 1981, belongs to the same era as the Beijing ape-man. However, this theory of the earliest origin of human beings has been overturned by two archaeological discoveries in China. After the liberation, archaeologists successively found ape-man fossils in Lantian in Shaanxi Province and Yuanmou in Yunnan Province.

The Lantian ape-man is 1 million years old, and the Yuanmou ape-man is 1.7 million years old.

So, how long is human history? In the last two or three decades, archaeologists have discovered many ape-man fossils on the African continent, giving us a new understanding of human history. In 1959, an almost complete fossilized ape-man skull and labor tools were found in Tanzania, dated to 1.75 million years ago.

In 1972, fossilized ape-man skulls, leg bones and stone tools were discovered in Kenya and dated to 2.6 million years ago. In 1973, it was reported that fossils of ape-man were found in Ethiopia about 3 million years old or 3 million years ago. From this point of view, human history is not 800,000 years, nor 1.7 million years, but more than 3 million years.

Historically recorded human society appeared 5,000 years ago.

Human history is now recorded over 6 million years. Since the 80s of the 20th century, many human fossils have been found around the world. The most important of these human fossils are:

1992-1995 inEthiopiaThe Alpha Lowlands found the ape (a subspecies of Archaeopteryx) 4.4 million years ago.

In 1998, another, more ancient subspecies of the terrestrial ape (the ancestral subspecies) was discovered in the same area, dating from 5.2 million to 5.8 million years ago. In Kenya, Africa, 2000.

The original man (Tugen species) was found 6 million years ago in the Tugen Mountains, and because it was discovered in 2000 years at the turn of the millennium, it is commonly known as the millennial man. Thus, the history of mankind is now recorded for 6 million years.

However, at the same time, we cannot rule out a 5% probability event for the duration of human beings, such as nuclear war.

Sudden invasion of aliens, human own immune system.

Disruption (e.g., HIV), climate change, the rise of more powerful organisms, etc., could lead to new extinction events in which human history would end prematurely if humanity was not spared.

Human history is now 250,000 years old.

Homo sapiens (scientific name: homo sapiens), also known as humans, 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.

Homo sapiens can distinguish itself from other living apes by having a significantly enlarged brain, relatively reducing most of the body's hair cover, and having a series of skeletal and muscular mass that adapts to habitual bipedal movements, including foot structures that lose the ability to grasp.

It is a terrestrial biped with limited ability to swim and dive and must be learned.

Exhibits strong changes in body size and proportions, as well as pigmentation, some of which may be related to the wide range of environments in which Homo sapiens lived.

Exhibits moderate sexual dimorphism in body shape.
