Charles Robert Darwin is famous for having given the concept of evolution to the world. He wrote two books on this subject: The Origin of Species and The Descent of Man. The Origin of Species is merely, an attempt to interpret the origin of species. Therefore, a more appropriate name for it would have been 'The Interpretation of the Origin of Species.' After the publication of Darwin's book, the Christian church bitterly opposed his interpretation, as people had come to regard Darwinism as the negation of the existence of God. But that is not true. Darwin's book, The Origin of Species, mentions God's name more than once. He concludes his book with these words: There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one: and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved. During the final days, Darwin suffered from ailments which could not be diagnosed. It is believed that he was totally dissatisfied with the contradictory explanations given in his book. He suffered from heart attacks twice and died in 1882.
