"Darwin's book, On the Origin of Species, was published in 1859. It is perhaps the most influential book that has ever been published, because it was read by scientist and non- scientist alike, and it aroused violent controversy. Religious people disliked it because it appeared to dispense with God; scientists liked it because it seemed to solve the most important problem in the universe-the existence of living matter. In fact, evolution became in a sense a scientific religion; almost all scientists have accepted it and many are prepared to 'bend' their observations to fit in with it."
