Because fossils take a long time to form, and human beings have lived on the earth for too short a time to form fossils.

How could it not be discovered, what is the Yuanmou man, what is the Peking man, isn't this the human fossil found, and then we think of how human beings evolved step by step.

Regarding the theory of evolution, I am sure that many people, especially religious people, will question it, and the question is why we can't find evolved humans? This question does blind some people who believe in evolution. Yes, because the theory of evolution says that humans evolved from apes, there must have been people who are still evolving, so why haven't they been found?
For this question, we must first understand the theory of evolution.

Fossils of humans and dinosaurs can be found, but why can't we find fossils of humans in evolution?

It's easy to trace the evolution of the automobile, which is less than a hundred years old, and many of the relevant design prototypes are still there. In contrast, tracing the evolutionary history of humanity is much more difficult. While humans now have many living primate relatives, many of the species that connect the evolutionary dots have become extinct.
Still, there are several ways evolutionary biologists can crack how humans evolved. In fact, in addition to biology, the field includes several different disciplines such as genetics, geology, archaeolinguistics, anthropology, and primates, to name a few. Of course, paleoanthropology also plays a key role, as we have had to resort to the fossil record to find clues about ancient primate and human ancestors.
After the Earth's vicissitudes, although the fossil record itself is incomplete, there is no shortage of fossil evidence that connects the various life forms on Earth into a giant tree of life, which scientists call the evolutionary tree (or genealogical tree).
Humans are at the very end of a branch on the evolutionary tree, called the "hominidae". Chimpanzees are located at the ends of adjacent branches. Going back about 5.4 million years to the human and chimpanzee branches, we can see that the two branches converge at one point, implying that humans and chimpanzees share a common ancestor.
While fossil evidence can help scientists reconstruct the evolutionary tree, morphological and genetic studies can also play a role. Genetic analyses of humans and chimpanzees are consistent with the fossil record. As a result, scientists know that humans and chimpanzees have a final common ancestor, although the exact species has not yet been identified.
However, paleoanthropologists have discovered many human fossils that can connect the unknown evolutionary history between that unknown common ancestor and modern humans. For example, in 1974, scientists discovered a fossil of an ancient human named "Lucy Maiden", who lived 3.2 million years ago and belonged to the Australopithecus species Alpha. This discovery supports the importance of bipedal upright walking in the evolutionary history of humans, an important milestone on the road to modern Homo sapiens.
In addition, in 1992, scientists discovered the fossil of an ancient human named "Aldi", who lived 4.4 million years ago and belongs to the Archaeopteryx species, which is the oldest hominin fossil ever discovered. Scientists are getting closer to that last common ancestor.

Of course, there is fossil evidence of human evolution, for example, on the Hemudu site, a lot of fossils have been found, and there are also certain oracle bone inscriptions, which illustrate the evolution of human beings.

We actually have some evidence of evolution, such as early Homo sapiens and Peking Man, and these are all evidence, and the whereabouts of the skull of Peking Man are not known yet. It is said that it sank into the sea.
-
At that time, a lot of fossils were unearthed and related to humans, for example, some ancient fossils unearthed in old Beijing, which can be used as the basis for human evolution.
-
A lot of fossil evidence of human evolution has been discovered, and it is through these fossils that the evolutionary history of human beings has been further verified. For example, the ancient human fossils of "Lucy Maiden", the ancient human fossils of "Aldi", etc.

The role of the tail is to maintain balance, but humans have evolved a complete balance system, and humans no longer need to jump around in trees like monkeys, so naturally there is no need for such advanced balancers.
The most important point of Darwinian evolution is natural selection, survival of the fittest. But there are some traits that do not affect the survival of organisms in the process of evolution, so why do these traits disappear as well? For example, the tail of a human being, the tail does not affect the survival of a person, and the process of natural selection will not eliminate people with tails, but those who are now in the middle of the world do not have tails.
So I think Lamarck's theory of using the spring before the abolition of the shortage is valid, because people don't need to use the tail, so the tail gradually degenerates.
The human tail is not because the tail makes the person with the tail eliminated, but because the effect of the tail on the person is small enough to be eliminated, the natural choice is to eliminate the tail and let it degenerate.

The tail of man degenerates during evolution.
Fossils of humans and dinosaurs can be found, but why can't we find fossils of humans in evolution?
Human beings rely on intelligence to win, and other functions are more degraded, so that human beings can devote all their time, energy, and ability to the development of intelligence. Superior intelligence can also be regarded as a miracle of the biological world, a unique function of human beings. >>>More

It would be nice to build a plasma spark tower.
After the mass extinction event (which occurred at the turn of the Permian and Triassic), our ancestors fell from the status of land hegemon, and most of them became extinct during the mass extinction event, while the surviving ones were suppressed by the later dinosaur ecology throughout the Mesozoic Era and forced to become nocturnal small animals. And this dark history has left a deep imprint on the only surviving descendants of the class Zygokosa - mammals. Almost all mammals have dichromatic vision – they lose the cone of two color visions in the dark, freeing up more space for rods that are sensitive but have no ability to discriminate color, because color vision is less useful in the dark, and the ability to perceive weak light is particularly important.
