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.

    Alex Prud'homme's remarkable work of investigative journalism shows how fresh water is the pressing global issue of the twenty-first century.

     Leslie Marmon Silko's new book, her first in ten years, combines memoir with family history and reflections on the creatures and beings that command her attention and inform her vision of the world, taking readers along on her daily walks through the arroyos and ledges of the Sonoran desert in Arizona. Silko weaves tales from her family's past into her observations, using the turquoise stones she finds on the walks to unite the strands of her stories, while the beauty and symbolism of the landscape around her, and of the snakes, birds, dogs, and other animals that share her life and form part of her family, figure prominently in her memories. Strongly influenced by Native American storytelling traditions, The Turquoise Ledge becomes a moving and deeply personal contemplation of the enormous spiritual power of the natural world-of what these creatures and landscapes can communicate to us, and how they are all linked. The book is Silko's first extended work of nonfiction, and its ambitious scope, clear prose, and inventive structure are captivating. The Turquoise Ledge will delight loyal fans and new readers alike, and it marks the return of the unique voice and vision of a gifted storyteller.
