In 1859, Charles Darwin shocked the world by proposing his radical theory of evolution by natural selection. A hundred and fifty years later, Darwin's theory still challenges our most precious beliefs. Introducing Evolution explains 'Darwin's dangerous idea' and shows how it has been developed and confirmed in recent years. Drawing on genetics, ecology and animal behaviour, this book brings Darwin up to date, exploring the profound consequences of the latest scientific discoveries. Introducing Evolution is the ideal modern guide to the most important idea ever to appear in the history of science.
