Charles Robert Darwin FRS was an English naturalist.

Background

Darwin's ideas developed rapidly from the return in 1836 of the Voyage of the Beagle

. By December 1838 he had developed the principles of his theory, but was conscious of the need to answer all likely objections before publishing. While he continued with research, he had an immense amount of work in hand analysing and publishing findings from the Beagle expedition, and was repeatedly delayed by illness.

Natural history at that time was dominated by clerical naturalists, whose income came from the Established Church of England

 as to whether the anatomy of brain structure was consistent with humans and apes having shared ancestry. The campaign was devastatingly successful for the Darwinian cause and brought new recruits.

Ape-men

Lyell was troubled both by Huxley's belligerence and by the question of ape ancestry, but got little sympathy from Darwin who teased him that "Our ancestor was an animal which breathed water, had a swim bladder, a great swimming tail, an imperfect skull, and undoubtedly was a hermaphrodite! Here is a pleasant genealogy for mankind... mankind will progress to such a pitch [that 19th century gentlemen will be looked back on] as mere barbarians". Huxley was busy attacking the old theory of divine providence as "anthropomorphism" and promoting the new Darwinian orthodoxy of "the passionless impersonality of the unknown and unknowable". He told Lyell that the range of brain sizes between people was greater than the difference between small-brained people and gorillas, and "Under these circumstances it would certainly be well to let go the head (as a way of distinguishing species) though I am afraid it does not mend matters much to lay hold of the foot."

Lyell began work on a book examining human origins. He toured archaeological sites in Britain and France

. He agonised about visiting the man who had made the Beagle trip possible and had given him much support since, but on 23 April sent his apologies and when Henslow died on 18 May was racked with guilt for not having seen him: "I never felt my weakness [a] greater evil".

Darwin was well into his work on domestication, obtaining skeletons of fowl and animals, borrowing specimens or stewing pigeons he had bred and rabbits he had requested, "I want it dead for the skeleton, not knocked on the head". This would eventually lead to his book The Variation of Animals and Plants under Domestication.

 was used to nursing, but was at her wit's end: "I have succeeded pretty well in teaching myself not to give way to despondency, [but can] only live from day to day." She wrote another touching letter to Charles, saying the "only relief [was to take] affliction as from God's hand [and] try to believe that all suffering & illness is meant to help us to exalt our minds & look forward with hope to a future state... When I see your patience, deep compassion for others, self command & above all gratitude for the smallest thing done to help you I cannot help longing that these precious feelings should be offered to Heaven for the sake of your daily happiness... It is feeling & not reasoning that drives one to prayer." Charles wrote "God Bless you" at the bottom of the note.

Lyell attended Huxley's continuing working-men's lectures, and was "astonished at the attentiveness and magnitude of the audience...[who would] devour any amount of your anthropoid ape questions". Human origins had been taboo to the scientific élite, but had long been featured in the radical

 press and the secularist Reasoner was currently running a series about evolution to combat "Theological Theories of the Origin of Man" with information about human fossils and Darwin's book. Huxley was tailoring his lectures to bring Darwinism to this wider constituency, saying that "Brought face to face [with chimpanzees or apes] these blurred copies of himself, the least thoughtful of men is conscious of a certain shock... It is as if Nature herself has foreseen the arrogance of man, and with Roman severity had provided that his intellect by its very triumphs, should call into prominence the slaves, admonishing the conqueror that he is but dust." Man might have come from the brutes, but "he is assuredly not of them... [man is not] degraded from his high estate [by descent from a] bestial savage,... [but] once escaped from the blinding influences of traditional prejudice, will find in the lowly stock whence Man has sprung, the best evidence of the splendour of his capacities; and will discern in his long progress through the Past, a reasonable ground of faith in his attainment of a nobler future." This was Darwinism supporting the creed of working class self improvement.

His requests to the wealthy enthusiasts who had taken up growing rare orchids brought large numbers of specimens. These would be a test of his theory: Huxley had once asked "Who has ever dreamed of finding an utilitarian purpose in the forms and colours of flowers?"

 that this would be a fashionable book to publish, but his illness returned, causing delay.

Huxley's argument, that natural selection was unproven until evolving varieties could be shown to form species which could not interbreed, turned Darwin's attention to experimenting, pollinating plants and sifting seeds. By collating his results in January 1862 he showed that primroses

 where Huxley was "preaching Darwinism pure & simple as applied to man.... [and] I made 'em listen.. I told them in so many words that I entertained no doubt of the origin of man from the same stock as the apes. Everyone prophesied I should be stoned and cast out of the city gate, but I met with unmitigated applause!"' Darwin was impressed that he had "attacked Bigotry in its strong-hold". Huxley published his lectures as a slim book on Man's Place in Nature.

Darwin persevered with his orchids, and the book, On the various contrivances by which British and foreign orchids are fertilised by insects and the good effects of intercrossing

,
was published on 15 May 1862, just in time to give Wallace a copy on his return from the far East. While demonstrating that orchids evolve mechanisms that allow for cross-fertilisation, and offering strong evidence for Darwin's larger arguments about variation, the volume also countered natural theology in what Darwin himself admitted was a "flank movement against the enemy." By showing that the "wonderful contrivances" of the orchid have discoverable evolutionary histories, he countered claims by natural theologians that the organisms were examples of the perfect work of the Creator. His interest in orchids continued and he had a hot-house built at Down House, as well as experimenting with other seedlings and "slaving on bones of ducks and pigeon" and variations in other farmyard animals. His illness led to his skin becoming inflamed and shedding, taking "the epidermis a dozen times clean off".

Because of the problems with eczema, Emma told him to grow a beard, and in December his friend Mary Butler commented on the idea of this "long beard".

In January 1863 he got word from Hugh Falconer

. It fulfilled Darwin's prediction that a proto-bird with unfused wing fingers would be found. Though Owen described it unequivocally as a bird, the subsequent finding that it had teeth left no doubt of its relevance to the Origin of Species. This sudden finding showed just how patchy the known fossil record was.

Huxley continued with his lectures to the working men, and a member of the audience took notes and published six fourpenny pamphlets which were brought together into a book which Darwin thought "capitally written... I may as well shut up shop altogether." On 4 February Lyell published his Antiquity of Man. To Darwin's disappointment Lyell had still not brought himself to clearly endorse Darwin's theory on species or on man, though he had "spoken out... even beyond my state of feeling as to man's unbroken descent from the brutes". Darwin's disappointment brought on ten days of vomiting, faintness and stomach distress. He was much better pleased to then receive Huxley's Man's Place in Nature, printed with a frontispiece showing a line of skeletons, with a gibbon at the end, stooping apes in the middle and upright man at the head, exclaiming "Hurrah, the Monkey Book has come". It included a jibe at Owen's ambiguous "ordained continuous becoming", and though some were horrified at this line of "gibbering, grovelling apes" the 1,000 copies sold quickly, requiring a reprint within weeks.

He began to recover in April 1864, sitting in his greenhouse at home and becoming fascinated by the purple loosestrife (Lythrum) he had been breeding for years. This has three kinds of flowers and Darwin explored the eighteen possible sexual combinations, counting the resulting seeds and testing their fertility. Only six "marriages" proved "legitimate", showing that this was another mechanism for cross-pollination. He tabulated the results of his experiments on seeds and wrote them up for the Linnean Society of London

. Around this time a Mrs. Becker wrote requesting something edifying for her ladies' literary society, so he sent her On the Sexual Relations of the Three Forms of Lythrum salicaria.

His bedroom, study and greenhouses became filled with climbers, creepers and coiling tendrils, and in May he began a short paper on these plants. He marked their tips to time their movements, and brought Hops indoors, using weights to try to slow their ascent as he sat ill in bed. By 13 September his paper had grown to a 118 page monograph, published by the Linnean Society.

, their careful preparations and lobbying succeeded in voting their nomination through despite furious politicking in opposition. Darwin was awarded the medal at the Council meeting on the evening of 3 November 1864.

Huxley had made arrangements for a dining club of close friends as select supporters of the evolutionary "new reformation" in naturalism, united by a "devotion to science, pure and free, untrammelled by religious dogmas", and it held its first meeting that same day.

, used his address to give the Origin faint praise and claim that "Speaking generally and collectively, we have expressly omitted it from the grounds of our award." After the address Huxley called for the Council minutes to prove this false. The minutes made no reference to such an exclusion, or to the Origin, to which Sabine argued that no allusion equalled express exclusion. The row continued afterwards, and the offending passages were altered in the official record of the address. Lyell used his after-dinner speech at the meeting to give guarded support to Darwin's theory in which he gave a "confession of faith as to the Origin", and said that he "had been forced to give up my old faith without thoroughly seeing my way to a new one." Darwin subsequently said that his friend's congratulations "are the real medal to me, and not the round bit of gold".

Early in 1865 Darwin's sickness worsened and he was overcome for almost eight months, lying in bed for weeks at a time, with Emma reading aloud to him. In May he heard of the suicide of Robert FitzRoy

Twice he quarrelled bitterly with me, without any just provocation on my part. But certainly there was much noble & exalted in his character."

 was now a qualified specialist in sickness and psychological medicine, and Darwin invited Dr. Chapman to Downe and gave him a long list of the symptoms he had suffered from for 25 years. A spinal freezing treatment seemed to help, and Darwin pressed on with his Variation Under Domestication.

Pangenesis

He now tackled the chapter of Variation setting out his hypothesis about heredity, that "pangenesis" brought "gemmules" from every cell of the body to the reproductive organs, where they formed the "true ovule or bud" that could pass on traits to the next generation. Huxley was dubious, cautiously writing "Somebody rummaging among your papers half a century hence will find Pangenesis and say, 'See this wonderful anticipation of our modern theories, and that stupid ass Huxley prevented his publishing them."

Times were changing. Lyell became embroiled in a row for having incorporated into Antiquity of Man whole paragraphs of a paper by Lubbock. The "X Club" continued to gain power in the British Association. Huxley's lectures were drawing huge crowds. Darwin had relapsed, but found a new doctor who put him on a crash diet

 cottage. Spencer, in his Principles of Biology, had coined the phrase "survival of the fittest", and though Darwin had struggled with the "detestable style" of the turgid tome, he now agreed with Wallace that it avoided the troublesome anthropomorphism of "selecting", though it "lost the analogy between nature's selection and the fanciers'."

 the Guardian reported that Darwin's theory "was everywhere in the ascendant... it was impossible to pass from Section to Section without seeing how deeply these views have leavened the scientific minds of the day."' The President, W.R.Grove, said it should be seen "in the history of our own race... the product of slow adaptions, resulting from continuous struggles. Happily in this country, practical experience has taught us to improve rather than remodel; we follow the law of nature and avoid cataclysms." Darwinism was now justifying British society rather than destroying it.

Hooker's speech ended by satirising their opponents of evolution at the 1860 meeting as an uncivilised tribe who saw "every new moon as a new creation of their gods" and ate "the missionaries of the most enlightened nation" for explaining the truth. "The priests first attacked the new doctrine and with fury... the medicine men, however, sided with the missionaries – many from spite to the priests, but a few, i could see, from conviction." Now after six years, the elders were baptised in the new faith and applauded their president for leading them out of the wilderness. Darwin was told of the stunned silence at first, followed by roars of laughter.

The religious press was "surprised and grieved" at this, but now the radical audience splintered into different directions. Following popular interest in Modern Spiritualism, winning over Robert Chambers and Wallace, they printed a pamphlet The Scientific Aspect of the Supernatural.

 for his lectures on Darwinismus. He had gone further, extending selection and struggle to society where it would "drive the peoples onward... to higher cultural stages." He had set out to rearrange all biological knowledge along Darwinian lines in his Generelle Morphologie. He was taken "by storm" when they met and, overawed, began speaking quickly in broken English, then found he could not understand Darwin's reply. They stared at each other for a moment, then burst into laughter and managed to communicate more slowly.
When the two volumes of Morphologie arrived later Darwin struggled for weeks with the number of new words like "phylogeny" and "ecology" as well as with the German, before giving up. His only hope was a translation, but the anti-clerical comments would prevent this. He gathered glimpses of Haeckel's ambition to achieve a universal Theory of Development embracing all human knowledge, if not his ideas of German Volk and support for Bismarck

, where William made a disparaging remark about the "Jamaica Committee". A furious Charles shouted that if he felt that way, he "had better go back to Southampton". The next morning Charles entered his son's bedroom and told him that he hadn't slept a wink, his anger had been cruel and he was sorry.

Variation under Domestication

Before Christmas 1866 Variation was sent to the printers, save for the last chapter. In this, Darwin wanted to overcome the persistent argument of divinely guided variation. He used the analogy of an architect using rocks which had broken off naturally and fallen to the foot of a cliff, asking "Can it be reasonably maintained that the Creator intentionally ordered... that certain fragments should assume certain shapes so that the builder might erect his edifice?" In the same way, breeders or natural selection picked those that happened to be useful from variations arising by "general laws", to improve plants and animals, "man included". Darwin was now openly including man in his theory, and wanted to add a chapter on this but the book was already too "horridly, disgustingly big" and he shortly decided to write a separate "short essay" on ape ancestry, sexual selection

Murray had to make two volumes of it, and being advised that it was hard going planned only 750 copies, though he later doubled that. Translators were eager to get to work: Carus into German, and Vladimir Kovalevsky

 into Russian - he was sent Murray's proofs, and successfully beat his publication date so that the earliest edition of Variation was in Russian.

During the Spring Darwin tried to find explanations in Sexual Selection for variations in that "eminently domesticated animal", mankind, and for the plumage of birds. As well as drawing on information, he experimented with dying pigeons red and trimming the feathers of game-cocks to see if this affected their desirability as a mate. The Duke of Argyll had thrown down a challenge with his book The Reign of Law, which collected criticisms of the Origin and put forward theories of divine design and providential law in a way that struck Darwin as "very well written, very interesting, honest, & clever & very arrogant". It made a particular point of the iridescent colours of hummingbird

s, claiming that this was beauty for God's sake without any earthly reason, not explicable by struggle. Wallace gave Reign of Law a withering review, pointing to the existence of stink bugs as well as beauty, and then became entangled in an exchange of detailed arguments with the Duke. To Darwin's despair, Wallace refused to accept a rôle for Sexual Selection.

Further damage to the Origin came from professor Sir William Thomson

, then argued convincingly that any single variation would be blended back into the population, so that to form a new species numerous variations would have to be created simultaneously, reintroducing the need for divine intervention.

By June Lyell was struggling to revise his Principles of Geology, though Darwin still hoped that he would at last "speak out plainly about species". Lyell found Darwin's proofs of Variation "most persuasive", but Darwin was struggling to sort out the changes and corrections he wanted. Encouragement came from the Reverend professor Charles Kingsley

 were "coming over [to] what the world calls Darwinism... The younger M.A.'s are not only willing, but greedy, to hear what you have to say, and... the elder... are facing the whole question in quite a different tone from that they did three years ago... I have been surprised at the change since last winter."

The proofs were finished on 15 November, and The Variation of Animals and Plants Under Domestication went on sale on 30 January 1868, thirteen years after Darwin had begun his experiments on breeding and stewing the bones of pigeons. He was feeling deflated, and concerned about how these large volumes would be received, writing "if I try to read a few pages I feel fairly nauseated... The devil take the whole book". The public were undeterred, and the 1,500 copies went within a week with a second printing at eleven days. The Pall Mall Gazette praised its "noble calmness... undisturbed by the heats of polemical agitation" which made the far from calm Darwin laugh, and left him "cock-a-hoop".
