born Sept. 10, 1941, New York, N.Y., U.S.

U.S. paleontologist and evolutionary biologist.
He received a Ph.D. in paleontology from Columbia University and joined the faculty of Harvard University in 1967. With Niles Eldredge (b. 1943), he developed the controversial theory of punctuated equilibrium (1972), a revision of Darwinism that proposed that the evolutionary creation of new species occurs in rapid bursts over periods as short as thousands of years, which are followed by long periods of stability. He was widely known as a popularizing writer on biological and evolutionary topics, especially in Natural History magazine; his numerous books include The Panda's Thumb (1980), The Mismeasure of Man (1981), and The Structure of Evolutionary Theory (2002).
