The Panda's Thumb: More Reflections in Natural History (1980) is a collection of 31 essays by the Harvard UniversitypaleontologistStephen Jay Gould. It is the second volume culled from his 27-year monthly column "This View of Life" in Natural History magazine. Recurring themes of the essays are evolution and its teaching, science biography, probabilities and common sense.
The title essay presents the paradox that poor design is a better argument for evolution than good design, as illustrated by the anatomy of the panda's "thumb"—which is not a thumb at all—but an extension of the radial sesamoid. Topics addressed in other essays include the female brain, the Piltdown Man hoax, Down Syndrome, and the relationship between dinosaurs and birds.
