The result is a thoroughly enjoyable and not too technical book narrated with inimitable grace and wit. In this story of an unrecognized chapter in the history of science, Gould takes us from ancient theories about inheritance and sex determination, through Mendel's famous experiments with his round and wrinkled peas, to speculations by Darwin and others about the rare male calicos. The struggles of early twentieth-century scientists to find and study rare male calicos in the hope of answering fundamental questions in the newly emerging field of genetics are explored in a
