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 horsewas a linear process culminating in the modern " Equus caballus"
He was Professor of
zoologyat Columbia Universityand curatorof the Department of Geologyand Paleontology at the American Museum of Natural Historyfrom 1945 to 1959. He was curator of the Museum of Comparative Zoologyat Harvard Universityfrom 1959 to 1970 and a Professor of geosciences at the University of Arizonauntil his retirement in 1982.
