When was humanity born? How many years was the birth of human beings

When did the first humans on Earth appear?

When was the universe born?

The dinosaurs became extinct 65 million years ago. 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. Regarding the development process of human beings, it is generally divided into four stages: 1. The 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.

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.

Many people are asking, you say that humans are not changed by monkeys, so when did humans first appear? The answer to this question may be beyond everyone's understanding, and based on current archaeological evidence, we can basically determine that humans may have appeared earlier than dinosaurs. Archaeologists in the United States found two fossils of human footprints in the stratigraphic fossils hundreds of millions of years ago, this kind of human footprints are no different from modern people according to the detection, of course, this kind of footprints did not wear shoes, we understand, human beings at that time were relatively primitive, and had not yet developed to the stage of wearing shoes.

In 1927, a geologist in the United States found a fossil of human footprints in a canyon in Nevada, and had put on shoes, according to the test, these fossils were excavated in the strata hundreds of millions of years ago, but strangely, according to the research of scientists, the shoes presented in the fossilized human shoe prints are very similar to a leather double-thread stitching technology shape, but the spacing of these lines is 1 3 inches, and then extend parallelly. There was no such thing in 1927, so scientists judged that on the earth at that time, human beings had not been able to have a pair of such shoes, and that human beings more than 200 million years ago could never have been uncivilized primitive. And it is a highly civilized and intelligent race.

This discovery has just been released, a fossil expert in our country, the famous Dr. Haitao also found a fossil footprint similar to that of human shoes in the Hongshan area of Xinjiang, China, but the strange thing is that the stratum where this fossil exists is more ancient, 270 million years ago, this shoe print is 26 cm long, showing a form of wide front and narrow back, and also has double epidemic prevention. And on this fossil, the left side of the entire shoe print is clearer than the right side, and the whole impression presents a posture of serious depression at both ends and shallow in the middle, which can already show that this is the shape of the left foot of human beings when walking. And this discovery is basically the same as the one in the United States, which is called the Obats Mystery.

Later, Dr. Haitao published a detailed ** on this matter in the journal of geographical knowledge, in which he said that it can be proved that on the earth, whether it is human civilization or overall biological behavior, a reincarnation evolution is being staged.

But in the United States, 65 million-year-old human footprints and a human finger fossil have also been found, and most importantly, a man-made hammer, in which the fossilized human footprints and the fossilized dinosaur footprints are overlapped, that is to say, a human footprint clearly stepped on the dinosaur footprint. Scientists have also studied this fossil in detail and found that this fossil was formed by extrusion from ancient strata, and there is no trace of fraud. The finger fossil and the inner screen hammer were found at the same time not far from this footprint fossil, in which the hammer is also inlaid with a small handle, the handle of this wood has not faded, which can show that the age of this hammer is very old.

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 from apes is their ability to walk upright on two legs. (2) Capable person stage.

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 Habilis

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