What was the beginning of humanity like, and who changed from humanity

Human history is now recorded over 6 million years. Humanity goes through four stages of development after becoming fully formed human beings:

One is the early ape-man, also known as Homo sapiens, which appeared between 3 million and 2 million years ago.

The second is the late ape-man, also known as Homo erectus. Its age ranged from about 1.8 million to 230,000 years ago.

The third is early Homo sapiens, also known as the ancients. It lived between 200,000 and 40,000 years ago.

The fourth is Late Homo sapiens, also known as Homo sapiens. Appeared 40,000 years ago to the present. Late Homo sapiens is modern humans.

Re-analysis of a skull dating back 100 million years has revealed that it was an early member of modern jawed vertebrates, meaning that the jaws include tens of thousands of living species of vertebrates, reptiles, mammals, and humans, from fish to birds. Acanths existed in the earliest pre-evolutionary periods of sharks and bony fishes, and this lineage eventually continued into human life.

Scientists have found fossils of the genus Echinosa in Europe, North America and Australia. Compared to other spiny sharks, they are relatively large, measuring 1 foot (about a meter) long, they have gills instead of lungs, and they have large eyes that feed on plankton.

The specific time is difficult to determine, because there is no standard that can count the previous ones, and only the ones after them are considered people, and human beings have gradually evolved from generation to generation! Generally speaking, it is believed that humans were created 5 million years ago.

Humans originated 5 million years ago.

1. Man was gradually evolved and evolved from Australopithecus over millions of years. Homo, also known as modern man (scientific name: homosapiens), is a species of primates, hominidae, hominus, and homo sapiens in biology, and evolved from apes and apes.

Elder Homo sapiens fossils suggest that modern humans evolved in the Great Rift Valley about 200,000 years ago.

2. Humans have more developed brains than other animals, and can perform complex calculations and abstract thinking. Human beings are social, and social interaction between individuals has created a wide range of traditions, customs, religious systems, values, and laws, which together form the basis of human society. People are especially good at communicating, collaborating, expressing themselves, communicating, exchanging ideas, and organizing things using spoken language, gestures, body language, and written language.

Generally speaking, the sign of human appearance is upright walking, and the time of the appearance of ancient humans, some people believe that it should be between about 5 million and 7 million years ago, although this conclusion is currently somewhat debated, but there is no doubt that it is at least about 4 million years old. Since the 20th century, archaeologists and paleoanthropologists have found fossils of ancient humans or remains of tools used by ancient humans in many parts of the world, such as Africa, Asia, and Europe. For example, the 1.7 million-year-old human bone fossil discovered by Yuanmou in China in 1965; The fossilized bones of Australopithecus australopithecus "Lucy", discovered in Ethiopia's Hadar Valley in 1974, were determined to be at least 3 million years old, and so on.

All the evidence points to multiple sources of human origin. The early evolution of humans was very slow, after about millions of years of evolution, only about 200,000 years ago, humans evolved into early Homo sapiens, about 100,000 years ago, humans evolved into late Homo sapiens, and modern humans belong to late Homo sapiens. Obviously, in this long evolutionary process, not all ancient humans can evolve into late Homo sapiens, that is, modern humans.

So where did the modern people scattered around the world today come from? Did they come from the same place, or did they evolve from local hominins, or was there something else? This is a question that anthropologists have been studying for a long time.

Now many people think that all modern people in the world are from the African continent, about 200,000 years ago, due to great changes in nature and ecology, the black pygmies in Kenya in East Africa began to go out of Africa, about 100,000 years ago, they reached the current Middle East, and then scattered to all parts of Asia, about 60,000 years ago, they arrived in today's America and Australia, gradually replacing the original Homo erectus around the world, and evolved into the common ancestor of modern people all over the world. In 1999, scientists from the Center for Human Genetics at the University of Texas in the United States and Chinese scientists jointly wrote an article pointing out that popular genetic studies proved that the ancestors of China's Homo sapiens, that is, the yellow race of Asians, were also black people from Africa, and that about 40,000 to 60,000 years ago, modern humans in Africa came to southern China and gradually replaced the ancients on the Asian continent. However, there are also some scholars who oppose the idea that humans share an African ancestry.

For example, some Chinese scholars believe that modern humans in China originated from early Homo sapiens in China, and they believe that ancient human fossils found throughout China prove that from Homo erectus, represented by Peking Man, to modern Chinese, there was no interruption, but only a small amount of hybridization was incidental.

Generally speaking, the sign of the appearance of human beings is the time of the appearance of ancient humans. Some believe that it should be between 5 million and 7 million years ago, and while this conclusion is currently somewhat debated, there is no doubt that it is at least around 4 million years old.

The early evolution of humans was very slow, after about millions of years of evolution. It was only about 200,000 years ago that humans evolved into early Homo sapiens. About 100,000 years ago, humans evolved into late Homo sapiens, and modern humans belong to Late Homo sapiens.

During this long evolutionary process, not all hominins were able to evolve into late Homo sapiens.

Nowadays, many people believe that all modern people in the world are from the African continent. About 200,000 years ago, due to great changes in nature and ecology,

The ancestors of humans were apes. Apes began to emerge in the Oligocene, about 30 million years ago. However, not all apes are direct ancestors of humans, and some apes are human"Uncle", some apes are human"Uncle".

The apes, which anthropologists consider to be the ancestors of humans, appeared very late. That is the Rama ape, named after Rama, a heroic prince from an ancient Indian epicThey lived about 10 million to 15 million years ago.

Rama apes were first discovered in Mount Sivalik, India, Pakistan. In the late 60s of this century, Rudaaucus found in the Early Eocene coal seams of Hungary also belonged to Rama ape. In particular, a fairly complete mandible fossil of the Rama ape type found in the limeba coal kiln in Lufeng County, Yunnan Province, China in 1976 is the most complete and closest to the early ancestor of humans of the same kind found in the world.

The time is also more than 10 million years ago. According to the excavations, the body of Lufeng Australopithecus is the size of a chimpanzee, with a short snout and underdeveloped canine teeth, which is not commonly used by ordinary apes"**".However, their intelligence is slightly higher than that of other animals, which, combined with their frequent activities in the open ground, prompts them to further divide their hands and feet.

Therefore, it is believed that Lufeng Australopithecus was able to grasp branches or other natural objects with their hands for defense and feeding. In this case, the hands have been divided, and the legs should be able to stand upright.

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.
