Stephen Jay Gould Quotes about Progress

The history of life is a tale of decimation and later stabilization of few surviving anatomies, not a story of steady expansion and progress.

Stephen Jay Gould (1991). “Bully for Brontosaurus: Reflections in Natural History”, W W Norton & Company Incorporated

Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress.

Stephen Jay Gould (1990). “Wonderful Life: The Burgess Shale and the Nature of History”, p.35, W. W. Norton & Company
