In Pursuit of the Gene: From Darwin to DNA

James Schwartz, . . Harvard Univ., $29.95 (370pp) ISBN 978-0-674-02670-4

Understanding the nature of genetic inheritance was essential for evolution to be accepted as the dominant paradigm in biology. In a masterful work, science writer Schwartz looks at the science and the personalities behind that understanding, ranging from Darwin's belief in pangenesis to explain the inheritance of physical variations to Hermann Muller's Nobel Prize–winning work on X-rays and genetic mutation. Although he discusses the contributions of such luminaries as Francis Galton, William Bateson, Gregor Mendel, Hugo de Vries and Thomas Hunt Morgan, Schwartz provides far more than character sketches. In a thoroughly accessible manner, he offers insight into the critical experiments each undertook and allows readers to share the excitement of discovery. He also does a fabulous job of demonstrating the social nature of science, showing how competition often leads to unseemly actions and how the unwillingness to part with a favorite theory leads to an idiosyncratic interpretation of data. Schwartz illustrates how, despite all of this, science continues to make progress and our understanding of the world continues to grow. Although the history of genetics has been covered many times before, Schwartz brings unbridled energy, strong writing and a fresh perspective. 42 b&w illus. (Apr.)
