Origin of variation between species

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter.

Origin of variation between species

Advanced search On the Origin of Species This, certainly the most important biological book ever written, has received detailed bibliographical treatment in Morse Peckham's variorum edition, The first edition also has a full bibliographic description in H. Horblit One hundred books famous in science,Grolier Club.

Peckham considers all editions and issues published in England of which he was aware, from the first of up to the thirty-ninth thousand of His work includes consideration of paper, type and bindings, as well as giving summaries of John Murray's accounts for each printing.

On the Origin of Species

The bibliography is an adjunct to the variorum text which shows the great changes which Darwin made to the five editions which follow the first. The author's minor changes in the printing ofwhich seem to have been ignored by all subsequent editors and even by the publisher's themselves, are brought to light, although Peckham was only able to see the issue of Since Peckham's list is likely to remain the standard bibliography of the work for a long time, it is worth while to summarise here the few apparent errors which I have noticed in it.

These are not surprising in view of the great difficulties involved, even in England, of sighting copies of all of the many issues. Within Darwin's lifetime he misses, so far as I am aware, only three, the issue of the fifth thousand and the twelfth and thirteenth thousands of He refers to the thirteenth thousand ofbut the same issue occurs with an earlier title page.

None of these three is mentioned in Murray's accounts. The thirteenth is the same as that of except for the date on the title page and the advertisements of Darwin's works. He describes the fifteenth thousand of and the twentieth ofboth of which he had seen, as being identical in format with the thirteenth of Whereas the latter is an octavo in eights, the former two, as well as the eighteenth ofare octavos in twelves.

He treats all the octavos in twelves as duodecimos, when Murray's accounts make it clear that they are octavos imposed in sheet and a half. Murray Darwins after this date occur in three forms, the standard, in cloth, those in Murray's Library series in cloth, and the cheap in paper covers.

All the issues are listed in the printing ofand all that I have seen do contain the summary of differences. Indeed I have never seen a Murray Darwin without it afterwhen it first appeared.

He also states that issues after are printed from the stereos of the two volume Library Edition repaginated. His statement on page [] that in the later issues, from the thirty-fifth thousand ofthe thousands given on the title pages are correct is not true because he has ignored the two volume Library Edition of which is the thirty-third thousand.

Finally, he considers only the editions and issues printed in England. Darwin was extremely keen that his ideas should be disseminated as widely as possible by translation, and that the changes in these ideas should also reach foreign editions.

To this end, he corresponded with translators and with publishers. Certainly, the fourth American printing of and the first Spanish of contain matter not present in any English printing.

The early German and French editions also need examination. Although Peckham describes and illustrates the bindings, he does not seem to have seen enough copies to notice even striking variations in them. Darwin had intended to write a much larger work on transmutation and had made considerable progress towards it when he received, on June 18ththe letter from Wallace which led to the publication of their joint paper in August.

His 'big book' as he called it was never published as such, but Variation under domestication represents the first part of it, and his surviving manuscript of most of the second part, Natural selection, although far from prepared for the printer, has appeared recently, edited by Robert C.

Hooker wrote to Darwinlate in after the publication of On the origin of species, 'I am all the more glad that you have published in this form, for the three volumes, unprefaced by this, would have choked any naturalist of the nineteenth century'.

He started work on the book on Tuesday July 20th,whilst on holiday at Sandown in the Isle of Wight.

The details of its composition and publishing are given in Life and letters Vol. To begin with, he expected it to be an abstract of perhaps as little as thirty pages, published in the Journal of the Linnean Society, but by the winter it was clear that it would have to be a book.

In March Lyell mentioned it to John Murray who accepted it in April, after seeing the first three chapters. It was all, except the index, in corrected proof by September 11th. Darwin was still calling it an abstract up until the end of March, and he roughed out a title page which Lyell showed to Murray.

Origin of variation between species

Natural selection is the key component of Darwin’s theory, as it explains the relationship between variation and the eventual evolution of a species.
