Every so often a giant emerges on the stage of science, someone who transcends the narrow boundaries of a particular line of research and alters our perspective of the world. E.O. Wilson is such a man. While studying ants, Wilson struggled to comprehend the evolutionary forces that have led workers to forage and soldiers to fight, and in doing so became the architect of a controversial new discipline -- sociobiology. His appreciation of the natural world has helped Wilson become an icon of our times -- the ant man who sought to explain nature on earth, and who now fights for its survival.
