Stephen Jay Gould

Stephen Jay Gould was an American paleontologist and evolutionary biologist who was born in 1941. He revised Darwin's theory of evolution, introducing his own concept of punctuated equilibrium. This states that evolution is not a gradual process but, rather, has static periods followed by brief bursts of change.

Gould was professor of zoology at Harvard University until he died on May 20, 2002. He also authored many books which bring the concepts of biology and evolution to the general public.
