On November Twenty-fourth, Eighteen Hundred Fifty-nine, was published "The Origin of Species." Murray had hesitated about accepting the work, but on the earnest solicitation of Sir Charles Lyell, who gave his personal guarantee to the publisher against loss, quite unknown to Darwin, twelve hundred copies of the book were printed. The edition was sold in one day, and who was surprised most, the author or the publisher, it is difficult to say.

Up to this time theology had stood solidly on the biblical assertion that mankind had sprung from one man and one woman, and that in the beginning every species was fixed and immutable.

"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.
