The Structure of Evolutionary Theory The Structure of Evolutionary Theory The Structure of Evolutionary Theory (2002) is Harvard paleontologist Stephen Jay Gould's technical book on macroevolution and the historical development of evolutionary theory. The book was twenty years in the making, published just two months before Gould's death. Aimed primarily at professionals, the volume is divided into two parts. The first is a historical study of classical evolutionary thought, drawing extensively upon primary documents; the second is a constructive critique of the modern synthesis, and presents a case for an interpretation of biological evolution based largely on hierarchical selection, and the theory of punctuated equilibrium
Evolutionary Theory (journal) Hypothesis. He also introduced what would become known as Van Valen’s law in this very same paper. The original name – law of constant extinction – states that “the probability of extinction for species and larger evolutionary groups bears no relation to how long it may have already existed”. He also contended that “The fossil record shows that lineages become neither more extinction-resistant nor more vulnerable over time”. One of the journals that originally rejected Van Valen’s article, Nature (journal) , recognized the importance of his work by confirming his work with several follow-up studies.
