Introduction to the Animal Diversity and Evolution Exhibition Hall: This exhibition hall shows what biological diversity is, describes the characteristics, naming principles and classification systems of existing biological groups, explains the origin of organisms, and reviews people's understanding of biological diversity. The understanding of biological origins and the development history of the theory of evolution lists the evidence from paleontology, morphology, embryology, zoogeography and molecular biology that supports the theory of evolution, and explains the relationship between continental drift and animal distribution.
