Charles Darwin 
Origin of Species [EPUB ebook] 

With an Introduction by Jeff Wallace.’A grain in the balance will determine which individual shall live and which shall die…’.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 rigour of science with the subtlety of literature, The Origin of Species remains one of the founding documents of the modern age.
