Papers and translations on a number of theoretical issues related to paleontology written by domestic and foreign scholars are edited by Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, and published by Nanjing University Press. The book is divided into two parts. The first part of the dissertation of Chinese scholars involves the study of Mesozoic plants and Permian classes using the principles and methods of branch system science. The origin, evolution and distribution of Mesozoic clam in South China are explained by the theory of marginal species multiplication. Theory and discuss the origin and early evolution of the ShiYan family of brachiopods. Taking the extinction of the Ordovician epoch as an example, this paper discusses the basic principle of extinction of the cluster, the concept of development at the same time and its application in the evolutionary analysis. The second part is the translation of the writings of foreign scholars, focusing on Punctuated Equilibrium and Phyletic Grad-
