    The Origin of Species
    Book Description:

    The theories propounded by Charles Darwin in The Origin of Species have had a profound and revolutionary effect, not only on biology but also on philosophy, history, and theology. His concept of natural selection has created eruptive disputes among scientists and religious leaders of his time and ours. The phenomenal importance of his brilliant work is universally recognized, but the present volume marks the first scholarly attempt to compile a complete variorum edition of The Origin of Species, covering all of the extensive variants in the six texts published between 1859 and 1872. Darwin's changes were extensive. His book grew by a third as he rewrote many passages four or five times, and in this edition Morse Peckham has recorded every one of those changes. A book of such distinctive dimensions, on a subject of such profound importance, will be of intense interest to historians of biology, evolution, science, literature, and cultural development. It will be an invaluable aid to the clarification and full comprehension of this complex and renowned scientific classic.

    “Much the greatest event that ever happened and much the best,” Charles James Fox said of the French Revolution—to me, a remark even more pertinent to the publication of On the Origin of Species. Its greatness would justify the preparation of a variorum text, but there are sounder reasons. The scale on which Darwin carried out five revisions makes it impossible, without such a text, to comprehend the development of his book. Of the 3,878 sentences in the first edition, nearly 3,000, about 75 per cent, were rewritten from one to five times each. Over 1,500 sentences were added,...

      An Historical Sketch of the Progress of Opinion on the Origin of Species, Previously to the Publication of the First Edition of This Work.

      I will here attempt to give a brief, but imperfect sketch of the progress of opinion on the Origin of Species.

      brief sketch

      The great majority of naturalists believe that species are immutable productions, and have been separately created.

      Until recently the great majority of naturalists believed that species were immutable productions, and had been separately created.

      This view has been ably maintained by many authors.

    • Introduction
      (pp. 71-76)

      When on board H.M.S. ‘Beagle,’ as naturalist, I was much struck with certain facts in the distribution of the inhabitants of South America, and in the geological relations of the present to the past inhabitants of that continent.

      These facts seemed to me to throw some light on the origin of species—that mystery of mysteries, as it has been called by one of our greatest philosophers.
