n the audience had any idea that they werewitnessing the scientific highlight of the century； they showed no sign of it。 no discussionfollowed。 nor did the event attract much notice elsewhere。 darwin cheerfully later noted thatonly one person； a professor haughton of dublin； mentioned the two papers in print and hisconclusion was “that all that was new in them was false； and what was true was old。”
wallace； still in the distant east； learned of these maneuverings long after the event； butwas remarkably equable and seemed pleased to have been included at all。 he even referred tothe theory forever after as “darwinism。” much less amenable to darwin’s claim of prioritywas a scottish gardener named patrick matthew who had； rather remarkably； also e upwith the principles of natural selection—in fact； in the very year that darwin had set sail inthebeagle。 unfortunately； matthew had published these views in a book called naval timberand arboriculture； which had been missed not just by darwin； but by the entire world。
matthew kicked up in a lively manner； with a letter to gardener’s chronicle； when he sawdarwin gaining credit everywhere for an idea that really was his。 darwin apologized withouthesitation； though he did note for the record： “i think that no one will feel surprised thatneither i； nor apparently any other naturalist； has heard of mr。 matthew’s views； consideringhow briefly they are given； and they appeared in the appendix to a work on naval timberand arboriculture。”
wallace continued for another fifty years as a naturalist and thinker； occasionally a verygood one； but increasingly fell from scientific favor by taking up dubious interests such asspiritualism and the possibility of life existing elsewhere in the universe。 so the theorybecame； essentially by default； darwin’s alone。
darwin never ceased being tormented by his ideas。 he referred to himself as “the devil’schaplain” and said that revealing the theory felt “like confessing a murder。” apart from allelse； he knew it deeply pained his beloved and pious wife。 even so； he set to work at onceexpanding his manuscript into a book…length work。 provisionally he called it an abstract ofan essay on the origin of species and varieties through natural selection —a title so tepidand tentative that his publisher； john murray； decided to issue just five hundred copies。 butonce presented with the manuscript； and a slightly more arresting title； murray reconsideredand increased the initial print run to 1；250。
on the origin of species was an immediate mercial success； but rather less of a criticalone。 darwin’s theory presented two intractable difficulties。 it needed far more time than lordkelvin was willing to concede； and it was scarcely supported by fossil evidence。 where；asked darwin’s more thoughtful critics； were the transitional forms that his theory so clearlycalled for？ if new species were continuously evolving； then there ought to be lots ofintermediate forms scattered across the fossil record； but there were not。
3in fact； the record asit existed then （and for a long time afterward） showed no life at all right up to the moment ofthe famous cambrian explosion。
3by coincidence； in 1861； at the height of the controversy； just such evidence turned up when workers inbavaria found the bones of an ancient archaeopteryx； a creature halfway between a bird and a dinosaur。 （it hadfeathers； but it also had teeth。） it was an impressive and helpful find； and its significance much debated； but asingle discovery could hardly be considered conclusive。
but now here was darwin； without any evidence； insisting that the earlier seas must havehad abundant life and that we just hadn’t found it yet because； for whatever reason； it hadn’tbeen preserved。 it simply could not be otherwise； darwin maintained。 “the case at presentmust remain inexplicable； and may be truly urged as a valid argument against the views hereentertained；” he allowed most candidly； but he refused to entertain an alternative possibility。
by way of explanation he speculated—inventively but incorrectly—that perhaps theprecambrian seas had been too clear to lay down sediments and thus had preserved no fossils。
even darwin’s closest friends were troubled by the blitheness of some of his assertions。
adam sedgwick； who had taught darwin at cambridge and taken him on a geological tour ofwales in 1831； said the book gave him “more pain than pleasure。” louis agassiz dismissed itas poor conjecture。 even lyell concluded gloomily： “darwin goes too far。”
t。 h。 huxley disliked darwin’s insistence on huge amounts of geological time because hewas a saltationist； which is to say a believer in the idea that evolutionary changes happen notgradually but suddenly。 saltationists （the word es from the latin for “leap”） couldn’taccept that plicated organs could ever emerge in slow stages。 what good； after all； is one…tenth of a wing or half an eye？ such organs； they thought； only made sense if they appeared ina finished state。
the belief was surprising in as radical a spirit as huxley because it closely recalled a veryconservative religious notion first put forward by the english theologian william paley in1802 and known as argument from design。 paley contended that if you found a pocket watchon the ground； even if you had never seen such a thing before； you would instantly perceivethat it had been made by an intelligent entity。 so it was； he believed； with nature： itsplexity was proof of its design。 the notion was a powerful one in the nineteenth century；and it gave darwin trouble too。 “the eye to this day gives me a cold shudder；” heacknowledged in a letter to a friend。 in the origin he conceded that it “seems； i freely confess；absurd in the highest possible degree” that natural selection could produce such an instrumentin gradual steps。
even so； and to the unending exasperation of his supporters； darwin not only insisted thatall change was gradual； but in nearly every edition of origin he stepped up the amount of timehe supposed necessary to allow evolution to progress； which pushed his ideas increasingly outof favor。 “eventually；” according to the scientist and hist
