Those who doubted or disputed this statement had no standing in society, and in truth, until the beginning of the Nineteenth Century, were in actual danger of death--heresy and treason being usually regarded as the same thing. Erasmus Darwin had taught that species were not immutable, but his words were so veiled in the language of poesy that they naturally went unchallenged. But now the grandson of Doctor Erasmus Darwin came forward with the net result of thirty years' continuous work. "The Origin of Species" did not attack any one's religious belief--in fact, in it the biblical account of Creation is not once referred to. It was a calm, judicial record of close study and observation, that seemed to prove that life began in very lowly forms, and that it has constantly ascended and differentiated, new forms and new species being continually created, and that the work of creation still goes on. In the preface to "The Origin of Species" Darwin gives Alfred Russel Wallace credit for coming to the same conclusion as himself, and states that both had been at work on the same idea for more than a score of years, but each working separately, unknown to the other. Andrew D. White says that the publication of Charles Darwin's book was like plowing into an ant-hill. The theologians, rudely awakened from comfort and repose, swarmed out angry, wrathful and confused. The air was charged with challenges; and soggy sermons, books, pamphlets, brochures and reviews, all were flying at the head of poor Darwin. The questions that he had anticipated and answered at great length were flung off by men who had neither read his book nor expected an answer. The idea that man had evolved from a lower form of animal especially was considered immensely funny, and jokes about "monkey ancestry" came from almost every pulpit, convulsing the pews with laughter. In passing, it may be well to note that Darwin nowhere says that man descended from a monkey. He does, however, affirm his belief that they had a common ancestor. One branch of the family took to the plains, and evolved into men, and the other branch remained in the woods and are monkeys still. The expression, "the missing link," is nowhere used by Darwin--that was a creation of one of his critics. Wilberforce, Bishop of Oxford, summed up the argument against Darwinism in the "Quarterly Review," by declaring that "Darwin was guilty of an attempt to limit the power of God"; that his book "contradicts the Bible"; that "it dishonors Nature." And in a speech before the British Association for the Advancement of Science, where Darwin was not present, the Bishop repeated his assertions, and turning to Huxley, asked if he were really descended from a monkey, and if so, was it on his father's or his mother's side!
