Published amid a firestorm of controversy in 1859, this is a book that changed the world. Reasoned and well-documented in its arguments, it offers coherent views of natural selection, adaptation, the struggle for existence, survival of the fittest, and other concepts that form the foundation of evolutionary theory.
