Darwin

1874 · rif. 6679 — London: John Murray 1874. Second edition. First edition first issue of the book in which Darwin finally gave his public account of two ideas he had withheld from the Origin: the descent of Homo sapiens and - his more original contribution - the mechanism of sexual selection. On page 2 of Volume I the word evolution appears the first appearance of the word in any Darwin work a year before the sixth edition of the Origin. The descent of man made him famous. Sexual selection required his readers to credit birds fishes and insects with something like aesthetic judgment - that females choosing generation after generation had driven ornament that natural selection alone could not explain. Wallace would not accept it and most of the scientific community followed him. Sexual selection remained a neglected corner of Darwinism for a century until Trivers 1972 Zahavi 1975 and Hamilton and Zuk 1982 vindicated female choice and placed it at the centre of evolutionary biology. . What Darwin Left Out of the Origin. First edition first issue of the book in which Darwin finally gave his public account of two ideas he had withheld from the Origin of Species: the descent of Homo sapiens from pre-existing forms and - his more original and more contested contribution - the mechanism of sexual selection. The Origin had deliberately excluded man from its argument "light will be thrown on the origin of man and his history" and had mentioned sexual selection only briefly as a special case within natural selection. Twelve years later with the evolutionary argument secured in the scientific literature and the public polemics largely past Darwin set out the two positions he had kept in reserve. The first made him famous; the second neglected for a century was resurrected only in the 1970s and is now one of the central research programmes in evolutionary biology. The twelve-year delay was not accidental. Darwin had been collecting notes on human descent since the Beagle years of the 1830s but had withheld them for strategic reasons. He had written to Wallace in December 1857 that he would avoid the subject of man as surrounded by too many prejudices even while admitting that it was the highest and most interesting problem for the naturalist. By 1871 the climate had changed. Huxley's Evidence as to Man's Place in Nature 1863 had done much of the defensive work; Lyell's Antiquity of Man 1863 had established deep human prehistory; and Haeckel's Generelle Morphologie 1866 had pushed the evolutionary argument onto the Continent and drawn the first explicit phylogenies of the human line. The Descent therefore arrived not as the opening of the controversy but as Darwin's own statement delivered at a moment when the main resistance had already been absorbed. The storm that had greeted the Origin did not repeat itself in 1871; Darwin wrote to a friend that he was surprised to find everyone talking about the book without being shocked and took this as a measure of the increasing liberality of the age. The first volume opens with a page that would prove diagnostic. On page 2 in the introduction Darwin refers to the principle of gradual evolution - the first appearance of the word evolution in any of his published works a year before its appearance in the sixth edition of the Origin. The word had hitherto belonged to embryology and to Herbert Spencer; Darwin had avoided it in the Origin in favour of descent with modification and natural selection partly because evolution still carried its older sense of the unfolding of a preformed germ and partly because Spencer's usage had given it metaphysical baggage Darwin preferred not to inherit. That he now allowed the word onto his own page marks a small but real shift in nomenclature: from 1871 forward the subject would be called evolution and the Descent is where Darwin formally joined the convention he had helped to make inevitable. The first volume and the opening chapters of the second are devoted to the argument for the descent of man from a pre-existing form. The strategy is cumulative: no single piece of evidence is decisive but each addition narrows the space of alternative explanations. Darwin begins with the homologies of bodily structure between man and the other mammals - the bones of the hand the arrangement of the viscera the musculature - arguing that these resemblances are inexplicable except as the signature of common descent. He proceeds to embryonic development where he reproduces the famous side-by-side comparison of a human embryo with that of a dog the Ecker-Bischoff figure Vol. I p. 15 arguing that in their early stages the two are practically indistinguishable and that embryology therefore preserves in miniature the shared ancestry of the vertebrate body plan. He turns to rudimentary organs - the vermiform appendix the musculus auricularis the coccyx the tubercle on the outer edge of the ear - as fossil evidence carried in the living body structures that make sense only on the assumption that they once served a function in a remoter ancestor. And he finally addresses the mental faculties arguing from comparative psychology - the affection of dogs the jealousy of birds the rudimentary reason observable in the higher apes - that there is no unbridgeable gap between human and animal cognition but rather a difference of degree. The argument leans on his cousin Francis Galton's Hereditary Genius 1869 which had established to Darwin's satisfaction that mental and moral qualities were inherited along the same channels as physical ones and could therefore be brought within the selective argument. The conclusion to the first part is stated with characteristic caution: that man is descended from some less highly organised form and that the grounds upon which the conclusion rests will Darwin writes never be shaken. A long chapter on the races of man mounts an argument against the polygenist position - then widely held particularly in the American anthropological literature after Morton and Nott - that the human races constitute separate species with separate origins. Darwin argues from the fertility of crosses from shared mental and moral characteristics and from the continuous rather than discrete distribution of racial traits for a single origin of Homo sapiens. His ethnographic scaffolding carries the prejudices of its period; his conclusion however is monogenist and anti-polygenist and in the politics of nineteenth-century race science that was the liberal position decisively opposed to the scientific racism then institutionalised in the American schools. The moral sense receives its own treatment. Against those who held that conscience and altruism must be divinely implanted because they could not be derived from self-interest Darwin argues that the social instincts - present in rudimentary form throughout the higher animals - provide a natural foundation for ethics. An animal that lives in a group is selected for behaviours that sustain the group; over generations those behaviours become internalised as moral feelings. It is the earliest sustained naturalistic account of ethics in the evolutionary literature and it is precisely the argument that Wallace a recent convert to spiritualism refused to accept. With the descent of man established Darwin turns in the remainder of the second volume to his second and originally his primary subject: sexual selection. This is the book's most sustained theoretical innovation. Darwin had been troubled since the 1850s by a class of biological traits that natural selection could not easily explain - elaborate male ornament ornate plumage antlers display behaviours bright colours - which often appeared to reduce the bearer's chances of survival rather than enhance them. The peacock's tail had become his standing example of the problem. Writing to Asa Gray in April 1860 only months after the publication of the Origin Darwin confessed that "the sight of a feather in a peacock's tail . makes me sick." The remark is only half a joke. It identifies the precise class of phenomena that resisted the argument of the Origin and it locates the theoretical problem that would occupy him for the next eleven years. The solution developed in the Descent was that a second mechanism distinct from natural selection was at work: selection not for survival but for reproductive success acting through mate choice and intrasexual competition. Sexual selection in Darwin's formulation has two components. The first - male-male combat - accounts for weapons and body size: antlers horns spurs large canines the fighting armature of rival males. The second - female choice - accounts for ornament: song colour display behaviour elaborate plumage. The implication was radical. Female preference exercised generation after generation was sufficient to drive the evolution of male traits that would otherwise be selected against. Darwin was asking his readers to believe that birds fishes and insects were in effect making aesthetic judgments and that those judgments had consequences at the species level. The comparative tour that occupies the bulk of Volume II - insects Chapters X-XI fishes amphibians and reptiles Chapter XII containing the figure of Plecostomus barbatus a South American siluroid catfish in which the male's mouth and interoperculum are fringed with a beard of stiff scale-like hairs of which the female shews hardly a trace birds Chapters XIII-XVI by far the longest treatment taking in courtship display vocal performance plumage and the geographical distribution of ornament and mammals Chapters XVII-XX - is in effect a six-hundred-page argument that this aesthetic mechanism is real widespread and responsible for most of the secondary sexual characters in the animal kingdom. Darwin's eldest daughter Henrietta Emma Darwin had read the manuscript and suggested corrections of style; in a letter of 28 March 1871 Darwin called her his very dear coadjutor and fellow-labourer and the book's argumentative clarity owes something to her editorial hand. The wood-engraved illustrations were drawn from life by the zoological artist T. W. Wood whose earlier work for Alfred Russel Wallace's Malay Archipelago 1869 had made him the best-placed draughtsman in England for the natural-history figures the Descent required; his economical diagnostic style suited the comparative method of the second volume where the illustrations carry much of the argumentative weight. The corrected proofs went to Murray on 15 January 1871 and the first issue of 2500 copies appeared on 24 February priced at £1/4/- the two-volume set. Demand was immediate: within three weeks a reprint had been ordered and by the end of March 1871 some 4500 copies were in print earning Darwin close to £1500. The religious press was hostile - the Edinburgh Review the Dublin Review and the Quarterly Review all published long attacks - but the scientific periodicals took the book more or less on its own terms. The most damaging review was the Quarterly's published anonymously in July 1871: Darwin guessed correctly that the author was St George Jackson Mivart Huxley's disillusioned former pupil whose own On the Genesis of Species January 1871 had already mounted a Catholic-metaphysical critique of natural selection. Mivart argued that the Descent would unsettle half-educated classes and licence moral relativism; Darwin felt the sting told Huxley that he expected to be viewed as the most despicable of men and was relieved when Huxley counter-attacked in the Contemporary Review that autumn. The episode permanently soured the Darwin-Mivart relationship and figures prominently in the 1874 second edition where Darwin silently corrected several of Mivart's specific objections without naming him. Translations appeared quickly: German Carus 1871 the two-volume Stuttgart edition that Darwin came to regard as authoritative and used when correcting his own text for later editions Dutch Hartogh Heys van Zouteveen 1871-2 French Moulinié 1872 Italian Russian and Swedish all within three years of the first printing. By the time Darwin died in 1882 the Descent had reached a wider international readership than any of his other works with the sole exception of the Origin itself. The present copy is the first issue of February 1871 distinguished from the second issue March 1871 2000 copies by four diagnostic features all of which are present and correct. Among them is the separately tipped-in Postscript leaf inserted after the Contents of Volume II on which Darwin acknowledges "a serious and unfortunate error" in his argument on sexual selection affecting Volume I pp. 297-9 and Volume II pp. 161 and 237. Darwin had realised too late to correct the printed text that he had conflated two distinct phenomena: the coincidence between the onset of sexual maturity and the appearance of secondary sexual characters which he had attributed to sexual selection and which he now recognised was better explained by natural selection operating at a correspondingly late life-stage. The Postscript does not rewrite the passages; it flags them and the opening of the passage on p. 297 of Volume I was entirely reset for the second issue. The first-issue leaves are therefore witnesses to Darwin's thinking in the act of correcting itself. Institutional copies of the first issue are securely held at Cambridge University Library Darwin's own copy in the Darwin Archive the British Library the Bodleian the American Museum of Natural History the Linda Hall Library the Huntington and the Norman Library lot 599 in the 1998 Christie's dispersal; auction appearances of complete first-issue sets in publisher's green cloth are not common at the better grades with the standard reference points the Garden 1989 Sotheby's catalogue the Norman 1998 Christie's sale and the Nordmann 2006 Christie's Paris dispersal. Freeman's four-feature collation is the operative test for assigning a given copy to the first issue rather than to the second. The present copy carries all four features and an indistinct pencil monogram apparently EH at the head of the Volume I half-title the only ownership mark in either volume; the marginal annotations and underlinings are the unsigned hand of a careful contemporary reader who worked through both volumes and who paused with particular attention at the bird and mammal chapters of Volume II. Wallace would not accept female choice. The disagreement had been building for years. Darwin and Wallace had corresponded intensively through 1867 and 1868 about the coloration of female birds the selective meaning of sexual dimorphism and - the point that eventually separated them - whether animals were capable of the kind of preference that Darwin's theory required. Wallace's 1868 Westminster Review essay on ornament already hedged: he would allow that bright colour could indicate vigour but not that it could be chosen for beauty alone. In his 15 March 1871 Academy review of the Descent he broke with Darwin publicly and in the papers that followed through the 1870s he argued that apparent ornament was really cryptic colouration or species recognition misread and that female choice - which required crediting animals with something like aesthetic sense - was implausible. Most of the scientific community followed Wallace. Sexual selection remained a neglected and faintly embarrassing corner of Darwinism for most of a century mentioned in textbooks as a historical footnote but rarely taken up as a research programme. It was resurrected only in the 1970s when Robert Trivers's 1972 parental-investment paper gave female choice a rigorous economic foundation Amotz Zahavi's 1975 handicap principle explained why costly ornaments could function as honest signals of genetic quality and W. D. Hamilton and Marlene Zuk's 1982 Science paper connected ornament to parasite resistance. Sexual selection is now one of the central research programmes in evolutionary biology and Darwin's six hundred pages are read as a founding document rather than a historical curiosity.
