Leonardo's Mountain of Clams and the Diet of Worms: Essays on Natural History

As in his previous collections of essays from Natural History magazine (Dinosaur in a Haystack, 1996, etc.), here again Gould artfully transports readers through the complex and enchanting realms of the natural world. This time, though, he peers less at nature than at scientists' attempts to understand and explain its wonders. Ranging far and wide through the history of science, Gould's sketches in ""humanistic natural history"" examine the ""grand false starts in the history of natural science""--for he contends that nothing is as ""informative and instructive as a truly juicy mistake."" In an essay on the Russian paleontologist Vladimir Kovalevsky, for example, Gould applauds his subject's meticulously detailed observations on the fossils of horses and his consequent development of an evolutionary history of the horse as an animal of European descent. Yet, Gould points out, Kovalevsky was mistaken, for horses had evolved in America and migrated to Europe. Another famous ""mistake"" Gould explores is Emmanuel Mendes da Costas's taxonomy of earth and stones according to Linnaeus's taxonomy of organic life. As usual, Gould proceeds to his conclusions by indirection; he opens his essay on Mendes da Costa, for instance, by disclosing how Linnaeus compared the shape and function of a clam to female sexual anatomy. Gould's elegant prose transmits the excitement and wide-eyed wonder of a scientist who never ceases to be amazed and amused at what he finds. 30 b&w illustrations. (Oct.)
