Simply Darwin tells the story of Charles Robert Darwin (1809–1882) and his theory of evolution through natural selection. On one level, the book portrays a dedicated scientist who, through careful observation and brilliant insight, became convinced that organisms were the end product of a long, slow, and natural process of development. On another level, it is an account of a cataclysmic change in our ideas about ourselves—a conceptual upheaval that continues to generate aftershocks—and heated debates—to this day.
