In the afternoon of January 14, Professor Shu Degan, an academician of the CAS Member and a professor of the Department of Geology, was invited to the High School Affiliated to Northwest University to bring a special academic report entitled "Cambrian Explosion and New Knowledge of the Origin of Human Beings" to the teachers and students of the second year of senior high school. Li Qingyan, Deputy Director of the Department of Geology, and related staff attended the event together.

At the presentation, Academician Shudegan used Darwin's classic propositions as a clue to systematically explain the three major origin milestones in the evolution of life: the origin of prokaryotic cells, the origin of eukaryotic cells, and the origin of the animal kingdom. He combined the long-term scientific research achievements of our university's research team to deeply introduce the "Three Acts Explosion Hypothesis" and clearly analyzed the grand plan of the formation of the three major animal sub kingdoms in stages during the Cambrian Explosion process. By presenting key fossil evidence such as Kunming fish and Haikou fish in the Chengjiang animal group, Academician Shu vividly reproduced the construction process of the "First Animal Tree" and profoundly revealed the significant scientific significance of the "First Fish in the World" as the ancestor of vertebrates. Its profound and easy to understand narration transforms the profound history of paleontological evolution into a fascinating journey of scientific exploration.

In order to enrich the content of the report and enhance intuitive understanding, the Department of Geology specially planned a micro science popularization exhibition on the campus of the Affiliated High School before and after the start and end of the report. The exhibition showcases multiple fossil specimens of ancient organisms and typical rock types commonly found in geological science, aiming to assist middle school students in fully understanding the ancient life and environmental background involved in the report through physical aids. The exhibition is led by outstanding members of the "Science Popularization Vanguard Team" from the Department of Geology, who are responsible for on-site explanations and interactions. This exhibition is a vivid epitome of the Geology Department's brand science popularization activity - the Earth Science "Mobile Museum", reflecting our department's consistent efforts to serve society with professional knowledge and stimulate young people's interest in science.
