On the Likely Origin of Species

Charles Darwin and On the Origin of Species

---

The title page reads 'Sixth edition, with additions and corrections. Three misprints have been noticed in this text, the first of which persists in all British and American editions, except those based on earlier texts, to this day; it is also transferred to translations. The last sentence of the third paragraph of Chapter XIV p. The word 'observed' makes nonsense of this sentence and, as the previous five editions read 'hidden as it is by various degrees of modification', is clearly a misprint for 'obscured'. In the glossary of scientific terms, the word 'indigenes' is misprinted 'indigeens'; this persists until In the Library Edition of that year the text reads 'indigeens', but there is an inserted erratum leaf Vol.

The one volume thirty-third thousand of has 'indigeens', but the thirty-fifth, of the same year, has 'indigens'; this latter form continues in all further Murray printings. Darwin himself uses 'indigenes' several times in the fourth chapter of the first and all later editions. Both forms are found in editions in print today. Finally, in this edition, the opening words of the Historical Sketch read 'I will here a give a brief sketch. This continues unnoticed through seventeen printings from the same stereos; but it was corrected when the whole book was reset for the forty-first thousand of This edition was reprinted, from stereos, later in the same year as the thirteenth thousand, and, again as the thirteenth, in On the verso of the title leaf of that of there are advertisements for nine of Darwin's works, whereas the reprint has ten.

The addition is the Expression of the emotions in its tenth thousand of As the first edition of the Expression of the emotions came out in November , the first issue of the thirteenth thousand must have been in press before this time, or else the new book would have been added. The issue has no inserted advertisements, but copies of may have them dated April The printing of is the final text as Darwin left it. Peckham drew attention to the little known fact that there are small differences between the text of and that of He knew that the printings of and were from unaltered stereos of , but was unable to see a copy of and had therefore to leave it uncertain whether these differences occur for the first time in that printing or in that of which he used for collation.

The issue was of 1, copies only. This number is as small as any, being equalled only by that of the first edition; and, whilst the latter has been carefully conserved in libraries, no attention seems to have been paid to this one. It does not seem to have been previously recognized as the first printing of the final text, and is remarkably hard to come by.

It was, incidentally, this edition which Samuel Butler had beside him when writing Evolution old and new in This printing is the eighteenth thousand, but, as it is important to know what was the first issue of the final text, it should be noticed that advertisements for The origin of species in other works by Darwin around mention the existence of both sixteenth and seventeenth thousands as well as this one.

These may be summarized as follows:. No copies of the sixteenth or seventeenth thousands have ever been recorded; it is difficult to see from the printing records how they can exist, although they may.

THE ECONOMY OF NATURE

We know that the eighteenth was in print in , yet the sixteenth is advertised three times in the following year. It is more likely that the compositor was making up from bad copy. The title page of this issue bears 'Sixth edition, with additions and corrections to There are no additions to the text and the pagination, from stereos, is unchanged.

There are however corrections, slight but undoubtedly those of Darwin himself. The two most obvious of these are the change from Cape de Verde Islands to Cape Verde Islands, and the change from climax to acme. The index is not altered so that Cape de Verde is retained there in this edition and later issues and editions, including the two volume Library Edition, which was entirely reset. The reason for the change of the name of these islands is not known, and Cape de Verde is retained long afterwards in issues of the Journal of researches printed from stereos.

However Darwin had no copyright in his Journal and only Cape Verde is found in Vegetable mould and worms which was first published in There is also one small change in sense in Chapter XIV. The details of these changes can be found in Peckham. In , and subsequently, the same stereos were used for the very many issues which appeared, in a variety of bindings. The first one to appear in a standard binding was the twenty-fourth thousand of All these issues, right up to the last in , continue to include the summary of differences and the historical sketch.

An entirely new setting in larger type, was made for the Library Edition of in two volumes and, after two reissues in that form, the same stereos, repaginated, were used for the standard edition of the Edwardian period. This Library Edition is uniform with a similar edition of The descent of man, and the same cloth was used for Life and letters.

The cheap edition was entirely reset for the forty-first thousand of The paper covered issues, which have been referred to above, have the title embossed on the front cover, and were produced for the remarkable price of one shilling, whilst the same printing in cheap cloth cost 2s. Both of these, the latter particularly, are hard to find. There are two issues by another publisher in the copyright period. In the first issue, the title page and text are those of the forty-fifth thousand of , with a list of Sir John's choices tipped in before the half-title leaf.

Seven hundred and fifty sets of the sheets were bought from Murray and issued in this form by Routledge and Kegan Paul in The second issue consists of Murray's fifty-sixth thousand, of , and there is no printed indication that this is a part of Sir John's series. The green cloth binding is however uniform with the rest of the series. The first edition came out of copyright in November , and Ward Lock printed it in the same year in the Minerva Library new series. The statement by Darlington, in Watt's reprint of , that his is the only reprinting of the first edition is not true.

Most of the other early reprints are based on the fifth thousand, but that of Collins in is based on the third edition. Modern reprints usually state that they are based on the sixth edition of , but they are actually based on that of There have been about reprints in English in this century, many of them in standard library series such as Everyman and the World's Classics. Some are important because they are introduced by leading scholars of evolution and show the changing attitudes towards Darwinism over the years; one, the Everyman of , has even had its introduction reprinted by the Evolution Protest Movement.

Almost all of them are bread and butter reprints in small type, but at a reasonable price. However there is one spacious edition, that for the Limited Editions Club of New York in ; this was designed and printed by the scholar-printer George Dunstan, at the Griffin Press, Adelaide. There are the usual abridged versions and extracts for schools, and even a coupon edition from Odhams Press.

There have been two facsimiles of the first edition; the earlier, in , omits the original index and substitutes its own; the later, in , is twenty millimetres taller than the original. In a concordance was published: Weinshank and Timothy T. In January , Asa Gray was arranging for an American issue of the first edition to be published in Boston, but two New York houses, Appleton and Harpers, were also considering it. The former got their edition out in the middle of January and Harpers withdrew. Darwin wrote in his diary for May 22nd that it was of 2, copies, but there were four separate printings in and it is not clear whether this figure refers to the first alone.

The title pages of the first two of these are identical, but the first has only two quotations on the verso of the half-title leaf whereas the second has three; the one from Butler's Analogy was added after Whewell and Bacon instead of between them as in the English second edition. The University of Virginia holds all four and their copies have been examined with a Hinman scanner. The texts of the first three are identical, in spite of the statement on the title page of the third, and follow that of the first English.

The fourth is considerably altered. It includes a supplement of seven pages at the end of author's 'additions and alterations. It also contains the historical sketch, in its earlier and shorter form, as a preface.

All four contain the whale-bear story in full. This total of twenty-nine is higher than any other scientific work, except for the first books of Euclid. The Autobiography also gives Bohemian and Japanese; the former refers to the Serbian, but he was misinformed about the latter; the first appeared in Darwin was not happy about the first German translation.

It was done from the second English edition by H. Bronn, who had, at Darwin's suggestion, added an appendix of the difficulties which occurred to him; but he had also excised bits of which he did not approve.

Reward Yourself

This edition also contains the historical sketch in its shorter and earlier form. Darwin's neglect of Archegosaurus and Hypsilophodon is noteworthy because the published analyses of these animals were anything but anti-evolutionary.

Creationism and evolution

The fact that these transitional-form candidates were not discussed in the Origin is important because it reveals that Darwin's treatment of Archaeopteryx was not anomalous. His apparent lack of interest in the London specimen is part of a pattern of interpretation that, I will now suggest, is made comprehensible by carefully scrutinizing his views on biological classification.

Understanding Darwin's views on species can be challenging. There is fairly widespread agreement Ghiselin , Beatty , Ereshefsky that he rejected the reality of the species category, meaning he regarded the Linnaean rank of species as a useful heuristic rather than a genuine division in the natural world. Passages such as the following excerpt from an letter to Joseph Hooker have been of particular importance in the debate on this issue:.

Here, Darwin seems to be suggesting that the dream of determining the necessary and sufficient conditions for membership in the species category is unrealizable. Regardless of whether he did or did not believe in the reality of the species category, remarks such as these are important for our purposes because they provide valuable insight into his views about the process of biological classification. Crucially, however, he did not believe that the process of determining whether a particular specimen should be ranked as a species or a variety is entirely haphazard: Hence the amount of difference is one very important criterion in settling whether two forms should be ranked as species or varieties.

Darwin , pp. That is, when we attempt to determine whether a specimen belongs to a particular species, the judgment we reach will likely be based on morphological comparisons with previously described members of the species.

If the investigator believes that the unidentified specimen is sufficiently similar to known varieties, it will be classified as a member of the described species. If it is not deemed sufficiently similar, it will be treated as a new species. With this in mind, we can turn our attention back to transitional forms and, in particular, how Darwin would go about classifying them. Casually speaking, a transitional or intermediate form is a species in which a quantitative trait of interest represents an approximate morphological median between two other species.

If a hypothetical transitional form is labeled B , we should expect it to be similar to a species A in some regards, but in other ways, it should resemble a species C. This is the way transitional forms were understood during the nineteenth century and, arguably, the same way we tend to conceive them today. The fact that transitional forms should have been coveted by Darwin appears obvious, in part because he held that evolutionary change is a very gradual process.

As Eldredge has recently discussed, Darwin believed that species initially form continuous populations. Over time, however, populations begin to diverge geographically, leading to subpopulations being subjected to different selective pressures. Specialist forms with extreme morphologies are favored over generalist ancestral types, and as time passes, the latter are eventually driven to extinction.

If, as Darwin suggested, evolutionary change occurs in this gradual manner rather than through rapid saltations, the gaps we observe in the fossil record must have formerly been filled by morphological intermediates. Because his detractors repeatedly criticized him for failing to produce evidence that transitional forms once existed, why did he not attempt to rebut these charges by pointing to the existence of an animal such as Archaeopteryx?

One reason is that it would be extremely difficult for someone with his views about classification to declare that a particular specimen is transitional. Darwin's thoughts on intermediate forms are most fully developed in the following selection from the Origin , which deserves to be quoted at length: It is all-important to remember that naturalists have no golden rule by which to distinguish species and varieties; they grant some little variability to each species, but when they meet with a somewhat greater amount of difference between any two forms, they rank both as species, unless they are enabled to connect them together by close intermediate gradations.

And this from the reasons just assigned we can seldom hope to effect in any one geological section. Supposing B and C to be two species, and a third, A, to be found in an underlying bed; even if A were strictly intermediate between B and C, it would simply be ranked as a third and distinct species, unless at the same time it could be most closely connected with either one or both forms by intermediate varieties. Nor should it be forgotten, as before explained, that A might be the actual progenitor of B and C, and yet might not at all necessarily be strictly intermediate between them in all points of structure.

So that we might obtain the parent-species and its several modified descendants from the lower and upper beds of a formation, and unless we obtained numerous transitional gradations, we should not recognise their relationship, and should consequently be compelled to rank them all as distinct species. According to Darwin, members of any given species vary in certain ways, but the amount of variation we allow within a taxon is finite. Again, this means that if the organism under consideration cannot be connected to previously known varieties, it will be classified as a new species.

If we follow Darwin and accept that there is no touchstone standard by which species can be distinguished from varieties, we are forced to maintain that most classifications are made in the manner just described. However, if systematic analyses are carried out exclusively by means of comparison with known forms, the task of classifying paleontological specimens becomes very difficult. As Darwin mentioned in conjunction with his pessimistic arguments about the geological record, fine gradations of form are not found because a fossilization is extremely rare and b phenomena such as erosion and the movement of the Earth's crust are constantly destroying the geological strata.

To understand why the incompleteness of the geological record made the identification of transitional forms difficult for Darwin, it is necessary to note that he regarded well-marked varieties as incipient species. Given this equivalence principle, the process of determining whether a particular fossil should be classified as a transitional form is similar to the procedure by which a specimen is judged to be a species or a variety. According to Darwin, the transitional designation can only be conferred upon a specimen if it can be connected to two seemingly distinct lineages by means of a series of intermediate varieties.
