George Gaylord Simpson (June 16, 1902 – October 6, 1984) was an American paleontologist. He was an expert on extinct mammals and their intercontinental migrations. Simpson was the most influential paleontologist of the twentieth century and a major participant in the Modern synthesis, contributing Tempo and Mode in Evolution (1944) and Principles of Classification and a Classification of Mammals (1945). Among other things, he is notable for anticipating such concepts as punctuated equilibrium (in his 1944 work, see quantum evolution), and dispelling the myth that the evolution of the horse was a linear process culminating in the modern Equus caballus

He was Professor of zoology at Columbia University and curator of the Department of Geology and Paleontology at the American Museum of Natural History from 1945 to 1959. He was curator of the Museum of Comparative Zoology at Harvard University from 1959 to 1970 and a Professor of geosciences at the University of Arizona until his retirement in 1982.

Quotes

"The regular absence of transitional forms is not confined to mammals, but is an almost universal phenomenon, as has long been noted by paleontologists."
