SECOND EDITION, second issue with an 1860 imprint and “fifth thousand” on the title page. In actuality, only 3,000 copies were printed, bringing the total to 4,250 with several revisions to the text. Roughly two copies of the first issue exist with an 1859 imprint.

Darwin considered the second edition of On the Origin of Species an improvement upon the first because it allowed him to correct errors and respond to the immediate wave of criticism that followed the book’s publication in 1859. The first edition sold out on the day of publication and provoked widespread scientific and public debate. Preparing the second edition only months later, Darwin revised numerous passages, corrected mistakes, clarified several arguments concerning natural selection and variation, and added a new historical preface acknowledging earlier evolutionary thinkers.
Darwin himself noted the extent of these changes, writing in the preface to the new edition that “numerous corrections have been made” and that he had taken the opportunity to address points raised by reviewers and correspondents. Among the most notable additions was the acknowledgment of earlier writers who had proposed evolutionary ideas, including Jean-Baptiste Lamarck and Robert Chambers. Darwin also modified certain phrasing to clarify his arguments and temper misunderstandings, making the second edition, in his own view, a more accurate and carefully expressed presentation of his theory of natural selection.
