"Gould is a natural writer; he has something to say and the inclination and skill with which to say it." —P. B. Medawar, New York Review of Books

With sales of well over one million copies in North America alone, the commercial success of Gould's books now matches their critical acclaim. The Panda's Thumb will introduce a new generation of readers to this unique writer, who has taken the art of the scientific essay to new heights.

Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.
