"The fossil record does not contradict genetics; it is the grand, multi-million-year motion picture of natural selection writing the history of life upon the Earth."

Archival Overview

Foremost paleontologist of the 20th century who integrated the fossil record into the Modern Evolutionary Synthesis in his 1944 masterpiece 'Tempo and Mode in Evolution', deciphering the evolutionary radiation of mammals and the Great American Biotic Interchange.

Biographical Record

George Gaylord Simpson (1902–1984) curated fossil vertebrates at the American Museum of Natural History, leading rugged fossil expeditions to Patagonia and the American West. Dissecting Mesozoic and Cenozoic mammalian fossils, Simpson brought rigorous statistical mathematics to paleontology.

In 'Tempo and Mode in Evolution' (1944), Simpson demolished vitalist and neo-Lamarckian claims that paleontology contradicted genetics, proving that fossil lineages—such as the horse family Equidae—evolved via variable rates (bradytelic, horotelic, tachytelic) fully consistent with natural selection acting on Mendelian genes.
