The Structure of Evolutionary Theory*

non-fiction by استیون جی گولد

Blurb

The Structure of Evolutionary Theory is a technical book on macroevolutionary theory by Harvard paleontologist Stephen Jay Gould, published only two months before his death. The volume is divided into two parts. The first is a historical study and exegesis of classical evolutionary thought, drawing extensively upon primary documents. The second is a constructive critique of contemporary Darwinian theory, and presents a case for a hierarchical interpretation of biological evolution based largely on the author's theory of punctuated equilibrium.
According to Gould, classical Darwinism encompasses three essential core commitments. These are: agency, efficacy, and scope. Agency is the unit upon which natural selection acts. For Charles Darwin, this fundamental unit was the organism. Efficacy encompasses the power of natural selection—over all other forces—in shaping evolution at ecological scales. Scope is the degree to which natural selection can be extrapolated to explain biological diversity at the macroevolutionary level, including the evolution of higher taxonomic groups.
