The development of science and the progress of mankind are all about filling in the gaps in the evolution of the earth's biological processes little by little under the unstoppable exploration. According to an article published by my country's scientific research team in the UK's " Nature " magazine on September 28, the content of the latest discovery of fossils in Xiushan, Chongqing mentioned that the new discovery of this time will fill a key evidence of the evolution of jawless fish to jawless fish. It is also because of this that it indirectly proves that humans first evolved from fish.
So why do I learn to swim? Could it be that those swimming champions are so powerful, but are actually Ancestral rebirth phenomenon ? In this way, the bacteria have a lot of balance. Maybe I can't swim because I don't have rebirth .
History of human evolution
Since CCTV News reported that the results of this research were obtained by the team of Academician Zhu Min from the Chinese Academy of Sciences and the Chinese Institute of Vertebrate Paleontology and Paleoanthropology in the past decade. The research objects this time are a large number of jawed fish fossils found in the "Chongqing Special Burial Library" and the "Guizhou Shiqian Fossil Library". The fills in to supplement the evolution process from jawless fish to jawed fish in human evolution history.
So why does it mean that the ancestors of human beings are fish? It would be too one-sided to say this. To know the reason, we must first understand what the jaw is.
jaw includes the maxillary bone and the mandible bone. jaw means that more types of food can be obtained by chewing and crushing food. Some people may be curious about how jawless eats. You can imagine how organisms like leech eat.
According to statistics, at least 99.8% of jawed vertebrates on the earth, including humans, which means that the ancestors of all animals evolved from fish , and even all human ancestors radiated from this land in our China. Speaking of this, many netizens may not be able to sit still. Some people say they cannot accept the conclusion that it is fish change.
In fact, the conjecture that humans evolved from fish had already existed a long time ago, but speculations out of thin air cannot represent the real pace of history, we need a real hammer.
Based on all paleobial group fossils that have occurred in our country, we can compare the early process of human evolution from fish.
In 1993, the Weng'an biota discovered in Weng'an Weng'an, Guizhou, my country, 610 million years ago fossils of algae and coral species were discovered. Because the country was inactive at that time, a large number of phosphate ore were needed, which also led to incomplete preservation of many fossils at that time. It was not until 2006 that a protected area was established.
In 1984, a fossil group was discovered in Maotian Mountain, Chengjiang, Yunnan. is a biological fossil from 530 million years ago. In this fossil, a large number of fossils from strange shrimp , trilobite , jellyfish , and other fossils in the water of the Early Cambrian period can be found.
Until the "Chongqing Special Buried Fossil Library" and "Guizhou Shiqian Fossil Library" reported this time, a large number of jawed fish fossils were discovered, which also kicked off the prelude to the history of human evolution.
The fossils discovered this time are mainly found in the strata of before . It is reported that the two fossil libraries discovered this time include fossils of five ancient fish, namely double-row Guizhou-toothed fish, Xinshu Fanjing Mountain Fish, Lingdong Tujia Fish, Wrinkled Shen's Knot Fish, and Miracle Xiushan Mountain Fish.
According to Academician Zhu Min, "This discovery once again pushed the complete jaw-like fossil record forward for 11 million years, and traced the origins of part of the human body, especially many characteristics of the face, to 436 million years ago." Academician Zhu Min also mentioned in the interview that some human structures can be vaguely found from the harmonious jaw-like fish, such as the nose, eyes, including the upper and lower jaw bones, and even the lips, which can be traced back.
, especially represented by Miracle Xiushan Fish, can be called the first human face . From the pictures in the data, we can indeed see these uniqueness. At least in that era, the evolution of these fish was advanced.

So when the fish evolved into jaw , it means that its food chain has changed , so it can choose more nutritious foods, such as some wild fruits on land, flowers, insects, etc., and even to eat other smaller fish, it continues to evolve sharper teeth and hard jaw bones.
So according to the next development, when jawed fish appear, it will evolve with appendage . In order to obtain more types of food, fish landing gradually occurs, and evolve into amphibian . Then, through different migration directions and evolution directions, it becomes various vertebrates and mammals. Then, starting from mammals, gradually begins the process of humans changing from monkeys mentioned in "Origin of Species".
Some people may have questions, what is an appendage?
appendage is the limb outside the main trunk of an animal, including the fish's puppet fins, animal limbs, dinosaur's claws and legs, and even bird wings, human legs and feet. all belongs to the scope of appendages. With an appendage, humans have evolved their own survival tools. Whether it is running or jumping or obtaining food, it is more convenient and quick, and it will even be of great help when escaping.
So why do the organisms on Earth come from the ocean?
First of all, this starts with the origin of the earth. As we all know, the newborn earth is a speck of dust. Through the accumulation of time, it continues to grow. After various centuries, different types of unique circles began to appear. These circles include the atmosphere, biosphere , hydrosphere , and lithosphere. Until the age of primitive organisms, marine life began to appear on the earth.
There was a study that the original form of the earth was actually , which was surrounded by water. It was really a planet made of water. With billions of years of evolution, has accumulated more and more dust in continuous movement, and geology has begun to change, and land has gradually formed. Therefore, the organisms on the earth have gradually adapted to the environment and evolved into the current biosphere.
However, through these ancient biological fossil circles, it is not difficult to predict that there must be more fossil circles that can mark the historical nodes of human evolution in other regions of my country, and scientists in our country will continue to make world-shaking discoveries.
The vast and mysterious ocean has nurtured all things, become the starting point of life, and carried the future of all things.
