Fossil finds in China provide insight into human history.
Recently, researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences made an unusual discovery. They discovered two fossil repositories in the early Silurian strata in the southwest of Guizhou and Chongqing.
This discovery will help rewrite the history of evolution “from fish to man.” The journal Nature also published four different articles describing the new discovery, writes SciTechDaily.
Humans are one of 99.8% of jawed jawed species. Most human body structures can be traced back to their origin. However, the most important moment of evolution was the appearance of the jaws themselves. This innovation remains a mystery. The reason for this is that fossils of early jawed vertebrates were not found in large numbers until the early Devonian period, about 419 million years ago.

At the same time, molecular evidence suggests that they must have been earlier than 450 million years ago. Therefore, there is now a large gap in the study of fossils of early jawed vertebrates. And it lasts at least 30 million years, including the time from the Ordovician to the Silurian periods.
At the same time, new finds by Zhu Ming's team helped shed light on the appearance of jawed vertebrates. This was helped by the discovery of 2 new fossil sites. Jawed fish are thought to have thrived in the waters of the South China region. It was at least 440 million years ago.
But by the late Silurian period, they evolved. The new sites help trace many human body structures back to ancient fish about 440 million years ago. They also provide other evidence for the evolutionary path. The depository of fossil fish in the upper layers of the Silurian system dates back to 464 million years ago.
Now it is considered the world's only early Silurian Lagerstätt depository with exceptional preservation. This place allows you to get to know the underwater world better. In addition, secrets and questions are hidden here that no one has even asked about the existence of life.
