Origin of Species

Darwin's theory of natural selection issued a profound challenge to orthodox thought and belief: no being or species has been specifically created; all are locked into a pitiless struggle for existence, with extinction looming for those not fitted for the task. Yet ''The Origin of Species'' (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and -- by implication -- within the human world. Written for the general reader, in a style which combines the rigor of science with the subtlety of literature, ''The Origin of Species'' remains one of the founding documents of the modern age.
