Explanation of biological evolution by two primary mechanisms: point mutations and natural selection; historical term used to refer to the synthesis of Weismannism, Darwinism and Mendelism in the period from 1900 to 1930, principally by Chetverikov, Haldane, Fisher, and Wright. This term can exclude the period c. 1930, which is often called Fisherism, and the next decade is then the Modern Synthesis. Sometimes the works of Dobzhansky, Simpson, and others around 1940 are also associated. Aka the neo-Darwinian revolution.

Cf. second Darwinian revolution.
