    Xinhua Chengjiang, Nov. 12 (Reporter Hu Yuanhang) The 2019 Cama Warrior Outbreak International Symposium was held in Chengjiang, Yunnan Province on the 12th, more than 130 experts and scholars from home and abroad exchanged the latest research results on the Camburo outbreak, to commemorate the 35th anniversary of the discovery of the Chengjiang biome.
    From the early Cambic period around 530 million years ago, almost all animal shapes, including vertebrates (gate-level classification units), emerged rapidly in just a few million years, a rapid evolution of life known as the Cambic outbreak. The Cambie outbreak is one of the fastest-growing multidisciplinary frontiers in paleontology, evolutionary biology and geosciences, and it is also one of the fields in which China's basic scientific research has a great influence and reputation in the international academic circles.
    The Chengjiang biome found in Chengjiang, where the conference was held, is located at the core of the Cambic outbreak, is a rare fossil treasure trove, vividly reproduces the true face of marine life 520 million years ago, fully shows the diversity of early Cambman life, traces the evolution of the vast majority of living animals to the beginning of the Cambman period, and provides extremely valuable evidence for revealing the mysteries of the Cambman outbreak, known as "the most amazing scientific discovery of the 20th century". On July 1, 2012, Chengjiang Animal Fossil Site was listed as a World Natural Heritage Site.
    so far
    , more than 260 species, including primitive vertebrates, have been found in Chengjiang animal groups, belonging to more than 20 animal types at the first level, said Zhao Fangchen, a researcher at the Nanjing Institute of Geology and Paleontology in Nanjing, China. Chengjiang animal group not only shows the complex and diverse structure of animals, but also reflects the differentiation and variety of animal ecological functions, such as the discovery of strange shrimp fossils show that the early Camaravin sea has established a "pyramid" food chain composed of complex ecosystems, giant carnivores ruled the Campyan ocean. Chengjiang biome as a whole, it shows us that the modern marine ecosystem dominated by later animals has been formed.

    a researcher at the Nanjing Institute of Geology and Paleontology in Beijing, China, revealed that new research shows that oxygen levels were the most critical factor in controlling the Camburo outbreak. Through high-precision geochemical research data, the teams of China, Britain and Russia found that the simultaneous fluctuations and amplitudes of seawater carbon and sulfur isotopes at the peak of the Cambidesic eruption were highly consistent with the number and magnitude of changes in animal fossil diversity. Over a period of about 2 million years from 514 million years now, the changes between carbon and sulfur isotopes are out of step, with carbon isotopes maintaining significant negative anomalies and sulfur isotopes fluctuating frequently. Coincidentally, there was a mass extinction of the global Camance animal population during this time.
    Chen Duyuan, one of the lead researchers on the Chengjiang biota and a researcher at the Nanjing Institute of Geology and Paleontology in
    , China, reports entitled "Evolution is more complex than Darwin thought - a brief description of the Cambic and human evolution eruptions". He argues that human evolution is advancing as fast as the Camburo outbreak. Among them, cultural drive is the main reason. As cultural genes become more complex, the driving force will become stronger and stronger.
    conference was organized
    by the Nanjing Institute of Geology and Paleontology of China and co-sponsored by the Chengjiang County People's Government. During the meeting, experts and scholars will also be organized to cap Tianshan Chengjiang biome, Meishu village small shell biome and other important fossil origin and profile for field scientific investigation.
    Reporters learned that in order to effectively protect Chengjiang biota fossils, Yuxi City, Chengjiang County has completely closed the Cammaid fossil reserve phosphorus ore, the fossil site has been strictly protected, prepared the "Yunnan Chengjiang Animal Group Paleontological National Geological Park Plan," "Chengjiang Fossil Land World Natural Heritage Conservation Plan" and "Chengjiang Animal Fossil Group Provincial Nature Reserve Protection Plan", the Yunnan provincial government has also issued the "Yunnan Province Chengjiang Fossil Land World Natural Heritage Protection Regulations." At the same time, in order to further publicize the scientific value of Chengjiang biome and carry out scientific dissemination, Chengjiang County in 2014 launched the construction of Chengjiang Fossil Land Natural Museum, the museum is basically ready to open, the end of 2019 is expected to open to the public.
