The Darwin Show

Steven Shapin

It has been history’s biggest birthday party. On or around 12 February 2009 alone – the 200th anniversary of Charles Darwin’s birth, ‘Darwin Day’ – there were more than 750 commemorative events in at least 45 countries, and, on or around 24 November, there was another spate of celebrations to mark the 150th anniversary of the publication of On the Origin of Species by Means of Natural Selection, or, the Preservation of Favoured Races in the Struggle for Life. In Mysore, Darwin Day was observed by an exhibition ‘proclaiming the importance of the day and the greatness of the scientist’. In Charlotte, North Carolina, there were performances of a one-man musical, Charles Darwin: Live & in Concert (‘Twas adaptive radiation that produced the mighty whale;/His hands have grown to flippers/And he has a fishy tail’). At Harvard, the celebrations included ‘free drinks, science-themed rock bands, cake, decor and a dancing gorilla’ (stuffed with a relay of biology students). Circulating around the university, student and faculty volunteers declaimed the entire text of the Origin.

On the Galapagos Islands, tourists making scientific haj were treated to ‘an active, life-seeing account of the life of this magnificent scientist’, and a party of Stanford alumni retraced the circumnavigating voyage of HMS Beagle in a well-appointed private Boeing 757, intellectually chaperoned by Darwin’s most distinguished academic biographer. The Darwin anniversaries were celebrated round the world: in Bogotá, Mexico City, Montevideo, Toronto, Toulouse, Frankfurt, Barcelona, Bangalore, Singapore, Seoul, Osaka, Cape Town, Rome (where it was sponsored by the Pontifical Council for Culture, part of a Vatican hatchet-burying initiative), and in all the metropolitan and scientific settings you might expect. The English £10 note has borne Darwin’s picture on the back since 2000 (replacing Dickens), but special postage stamps and a new £2 coin honoured him in 2009, as did stamps or coins in at least ten other countries.

Darwin had an anniversary Facebook group dedicated to him: its goal was to have 200,000 unique Happy Birthdays posted by 12 February and a million ‘friends’ by the November anniversary of the Origin. The group also planned a mass ‘Happy Birthday, Darwin’ sing-along, but I don’t think this actually happened. Then there were the Darwin-themed T-shirts, teddy bears, bobbleheads, tote bags, coffee mugs, fridge magnets, mouse mats, scatter cushions and pet bowls; the ‘Darwin Loves You’ bumper-stickers, the ‘Darwin Is My Homeboy’ badges, and the ‘I ♥ Darwinism’ thongs. The opening line of the year’s most substantial historical contribution, Adrian Desmond and James Moore’s Darwin’s Sacred Cause, is: ‘Global brands don’t come much bigger than Charles Darwin.’ Quite right.

Darwin freely confessed to late-onset philistinism: ‘My mind seems to have become a kind of machine for grinding general laws out of large collections of facts.’ He eventually found Shakespeare ‘so intolerably dull that it nauseated me’. But the imaginative arts lined up to pay tribute. In Cambridge, Ian McEwan and A.S. Byatt spoke about their ‘literary relationship with Darwin’. The joint Yale-Cambridge museum homage, Endless Forms: Charles Darwin, Natural Science and the Visual Arts (at the Fitzwilliam in Cambridge and the Yale Center for British Art), rightly called ‘the best show of the year’, was a brilliant exploration of the impact of evolutionary ideas on painting, photography and the illustrative arts, and of the fecundity of Darwin’s responsiveness to the visual impact of nature’s richness, diversity and intricacy. The Natural History Museum in South Kensington hosted the cleverly named After Darwin: Contemporary Expressions – installations, video, film and literary works inspired by Darwin’s late work The Expression of the Emotions in Man and Animals. And Darwin’s great-great-granddaughter Ruth Padel published Darwin: A Life in Poems, evoking the emotional nexus from which the Origin emerged:

‘I never dreamed
that islands sixty miles apart, made of the
same stone,
of nearly equal height in the same climate,
could have different tenants.’ Fast forward
twenty years
and you see him write of this scatter-burst of
rock in open sea,
‘We seem brought near that mystery of
the first appearance of new beings on the

The Rambert Dance Company produced a new work, The Comedy of Change, as their contribution. The ballet’s scientific adviser ‘gave a lecture about Darwinian ideas’, after which she and the choreographer ‘did some tango moves’ to evoke the mating dances of birds. The University of Birmingham celebrated with The Rap Guide to Evolution, featuring the ‘African-American Atheist Rapper Greydon Square’, the ‘self-styled “Walking Stephen Hawking”’. In Manhattan, the Ensemble Theater produced Darwin’s Challenge (‘On his trip aboard the HMS Beagle, Charles Darwin wanders into a cave on Galapagos and finds himself on the set of a 21st-century reality TV show … He gets kicked off in Act Two’) – a play which Scientific American dyspeptically summed up as ‘maybe the first attempt ever to hijack the life of the theorist of natural selection as a medium for cracking fart jokes’.

Radio 4’s Something Understood discussed whether geniuses were born or made, taking Mozart and Darwin as exemplars and underlining the case for Darwin with a song called ‘Charlie’ by the one-time anarcho-punk group Chumbawamba: ‘All of nature in its place/By hand of the designer/Comes our Charlie spins the world/From here to Asia Minor/In between the Platypus/And perfect Aphrodite/Charlie come with opposing thumb/To question the Almighty.’ And, uncategorisably, 2009’s Burning Man Festival, in the vast Black Rock Desert of Nevada, featured the theme of ‘Evolution’: the 12-metre human shape – burned to extinction at festival’s end – rose above a ‘tangled bank’ consisting of irregular wooden triangles … At night the tangled bank came alive with luminous life forms scratching, crawling and slithering their way through it … Strange Ur-creatures peep outward from the surface of this primal soup. The central tree supporting Burning Man, beribboned with a double helix, existed in flux: switching on and switching off, changing colours unexpectedly.

The installation, meant to symbolise the work of evolution, itself instantiates evolution’s historical trajectory from counterculture to counterculture, with only a brief stop in between to pick up paying passengers.

Then there were the national and international conferences (scientific, historical, philosophical and literary), the special issues of academic and general-interest periodicals, the television and radio shows, and of course the books, including at least four new biographies specially for children. Darwin Year celebrates something much more diffuse, more general and more consequential than the life and works of a great Victorian naturalist. Darwin has escaped from disciplinary confines, and even from academic ones, because what he did is supposed to have changed ‘the way we think’ – lots of us, if not all of us – about the world, about ourselves and about how we go about knowing the world. It is a celebration – yet another – of a moment that is said to have ‘made the modern world’, definitively, exhaustively, irreversibly.

The New York Times announced that ‘the theory of evolution really does explain everything in biology,’ but that’s rather modest in the context of current celebratory hype. In now canonical versions, Darwin’s idea of evolution through natural selection – his ‘dangerous idea’ – was, as Daniel Dennett famously said, ‘the single best idea anyone has ever had’. Better than any idea of Newton’s or Einstein’s, and better than any idea had by Jesus or Aristotle or Hume or that other great 12 February 1809 birthday boy, Abraham Lincoln. It ‘unifies the realm of life, meaning and purpose with the realm of space and time, cause and effect, mechanism and physical law’. If T.H. Huxley was ‘Darwin’s bulldog’, the Oxford emeritus professor for the public understanding of science, Richard Dawkins, has been called his unmuzzled rottweiler; according to Dawkins, Darwin’s idea wasn’t just a great one (‘the most powerful, revolutionary idea ever put forward by an individual’), it is essentially the only idea you need to explain life and all its phenomena: ‘Charles Darwin really solved the problem of existence, the problem of the existence of all living things – humans, animals, plants, fungi, bacteria. Everything we know about life, Darwin essentially explained.’ One-stop shopping for the inquiring mind in a hurry, though one can wonder why an idea of such evident and all-encompassing power would – a century and a half later – need this aggressive marketing.

While Dawkins concedes that Darwin ‘made some mistakes’ – for example, he got genetics all wrong, but so did everyone else in the 19th century before there was any genetics to get right – the sociobiologist E.O. Wilson will have none of that: ‘The man was always right.’ Uniquely among the sciences, evolutionary biology comes with a patronymic, and so another oddity is why – if we take some of the wilder rhetorical flourishes literally – evolutionary theory is talked about as if nothing much has changed scientifically since Darwin’s time. Scientists don’t routinely refer to physics as Newtonianism or claim that ‘everything we know about physics, Newton essentially explained.’

Put aside for a moment whether any of these extravagant claims about modernity-making is even approximately right: not whether Darwin’s specific evolutionary ideas were powerful and broad (which they undoubtedly were) but whether they have marked the world in indelible ways and whether in fact they constitute the universal explanatory tool that some claim they do – whether, as Dawkins says, we ‘have no choice’ but to concede Darwinian supremacy and whether Darwinian evolution has the power to nail down almost all the problems that have occupied thinkers across disciplines and cultural practices. The evolutionary biologist Theodosius Dobzhansky once said that ‘nothing in biology makes sense except in the light of evolution,’ and now an anthropologist claims that ‘nothing about humans makes sense except in the light of evolution.’ (Nothing.) Under the influence of a scientific rush of blood you get something that sounds like a recommendation that every mode of inquiry other than evolutionary biology and its allied disciplines shut up shop and go home. So we have the evolutionary anthropologist Robert Foley: ‘For centuries, humans have wondered about why humans are the way they are, and they’ve turned to philosophy and to religion to answer that question.’ But humans should stop doing that: Darwin allowed us to set philosophy and religion aside and to see that the answers to such questions either belonged to evolutionary biologists or they were nonsensical. That is, however, a step too far for some otherwise sympathetic scientists. As the geneticist Steve Jones put it, Darwin Year has encouraged ‘vulgar Darwinists’ in their already souped up tendency misleadingly to treat evolutionary biology as ‘a universal solvent that can sort out the most recalcitrant problems of society, consciousness, politics, literature and more’.

Even conceding the more expansive claims for Darwin’s genius and influence, we’re still some way from understanding what the festivities have been about. There are other claimants for the prize of towering scientific genius, and for ‘making the modern world’, but none of them has been the occasion for global festivities on anything like this scale. The 400th anniversary of Galileo’s birth was 1964, and Descartes’s 1996; Newton’s Principia turned 300 in 1987; Einstein’s Wunderjahr papers in Annalen der Physik, changing the way physicists think about space, time and matter, had their centenary in 2005. All were duly marked, mainly by historians, philosophers and physicists, but there was nothing remotely approaching Darwin 200. Even if we had an unambiguous metric for ranking scientific genius and modernity-making – one by which Galileo, Descartes, Newton and Einstein were chopped liver compared to Darwin – neither genius nor influence would be a sufficient explanation for the events of 2009.

The very idea of paying homage to the great scientists of the past is problematic. Scientists are not widely supposed either to be heroes or to have heroes. Modern sensibilities insist on scientists’ moral equivalence to anyone else, and notions of an impersonal Scientific Method, which have gained official dominance over older ideas of scientific genius, make the personalities of scientists irrelevant in principle. Honouring past scientists is therefore a different sort of thing from, say, paying homage to history’s generals, politicians or, indeed, imaginative artists. You don’t need to subscribe to a strict form of Pascal’s theory of history (had Cleopatra’s nose …) to accept, in one way or another, that individuals and circumstances can make a difference to the course of events. Had Lincoln not been president, the Civil War would quite probably have had a different trajectory and outcome; had Bush and Cheney not run the show, it’s plausible that Iraq would have not been invaded as a response to 9/11 or that an invasion would have turned out differently; and had Mozart not lived there would have been no Figaro. But it’s hard to accept that if Watson and Crick – clever and ambitious though they were – had not found the double helical structure of DNA, no one else would have done so.

Artists create; scientists discover. That’s our usual understanding of the thing, and scientists – together with some of their philosophical allies – have been in the van of insisting so. (That’s one way in which ‘relativism’ and ‘social constructivism’ are commonly opposed.) If science is discovery and not invention, then it follows that discoverers’ relation to what they reveal is different in both intellectual texture and moral resonance from Mozart’s relation to his operas, Shakespeare’s to his plays, and even Bush’s to his wars. You couldn’t say of Figaro or Lear or the Iraq war that they were waiting there to be ‘discovered’. ‘Something of that sort’ may well have come into being, but an example of ‘something like’ Figaro is Salieri’s Axur, Re d’Ormus or even Abba’s ‘Waterloo’. You don’t necessarily have to construct counter-factual histories to support this sort of sensibility. Scientists are often said to hit on ‘the same’ (or ‘nearly the same’) idea at about ‘the same’ time: Galileo, Scheiner and several others on sunspots; Leibniz and Newton on the calculus; Priestley and Scheele on oxygen; Steven Weinberg and Abdus Salam on electroweak gauge theory; and, of course, Darwin and the undercelebrated Alfred Russel Wallace on evolution by natural selection. Every instance of what has been called ‘simultaneous discovery’ lends credence to the notion that the individual does not matter in the course of science, or matters in a very different sort of way from authorial mattering in the creative arts. Homage to the scientist and to the artist sits astride one of our great cultural faultlines. What is owed to reality, and what to the creative work – even the imaginative, literary and political work – of those who are said to lift the veil of reality’s structural and dynamic secrets?

You can still say, with perfect accuracy, that the Origin is much more than its ‘essential’ theory of natural selection: it is a book, a magnificent theatre of persuasion, ‘one long argument’ (as Darwin called it), supported by masses of arduously compiled evidence, ingeniously organised and vouched for by a special individual, with known special virtues and capacities. (Historical reactions differed even on the recognition of the Origin’s literary qualities: George Eliot sourly considered the book ‘ill-written and sadly wanting in illustrative facts’, lacking ‘luminous and orderly presentation’, and Karl Marx complained about ‘the clumsy English style’.) As Richard Horton observed in a special issue of the Lancet, Darwin’s fame, unlike that of today’s scientists, was ‘based on books … His books were neither summaries nor simplifications: they were the core of his originality.’ Writing books was not, for Darwin, an irritating obligation to report on discoveries: reporting and persuading were, for him, seamlessly joined creative acts. He liked writing and took enormous pains in composition; he cared deeply about its power and effects on readers. Whatever might be meant by the ‘essence’ of evolution by natural selection is something you could say was discovered: the text called the Origin was composed, in exactly the same sense that Figaro was composed, artfully put together, invented. Wallace’s 1858 paper ‘discovering’ evolution by natural selection stung Darwin into a frenzy of long pent-up composition, so it’s plausible to identify at least two discoverers of the theory but only one author of the Origin. Wallace himself was well aware that it was one thing to come up with a theory but a much greater thing to make it credible: he thought of himself as a mere ‘guerrilla chief’ of evolution while Darwin was ‘the great general’, mapping out the grand literary and political strategy to make natural selection stick in the culture.

Paradoxically, this year’s events have been a celebration of a historical figure and his historical work in which specifically historical interests have been notably marginal. The party is one in which the present, with its pressing present concerns, processes fragments of the past in roughly the same way that assorted blocks of white fish, bulked out with filler, are processed into fish fingers. Myths have a market; myth-busting has a small one; setting the historical Darwin in his Victorian intellectual and social context has practically none at all.

Barry Werth’s Banquet at Delmonico’s – a fine popular book on Herbert Spencer’s American success that has been rather swamped by 2009’s Darwinmania – underlines the fact that, successful as the Origin was, large numbers of 19th-century readers got their understanding of ‘evolution’ from Spencer’s very different, teleologically orientated works. Countless others took in their evolutionism from the progressivist Vestiges of the Natural History of Creation, a ‘Victorian sensation’ anonymously published in 1844 by the Scottish journalist Robert Chambers and abominated by Darwin as just the sort of thing that was bound to vulgarise evolution and to make it scientifically disreputable. As James Secord shows in the introduction to his edition of Evolutionary Writings, Vestiges was, at the time Darwin wrote, ‘the one evolutionary book that all English-speaking readers could be expected to know’.

The historical road to recognising the significance and the power of Darwinian natural selection has been neither straight nor smooth. Just after the Darwin commemorations of 1909, the New York Times blandly announced that natural selection

has ceased to be regarded as the key to all the biologies; so that it is probable that his fame in this regard reached its acme last year … The general attitude of contemporary biologists towards the great achievement of Darwin differs considerably from the chorus of universal acceptance which was current in the 1870s and 1880s. Instead of having solved the problem of the origin of species, Darwin, it is now recognised, only raised the question.

That is to say, natural selection as ‘the key’ to organic change needed to be synthesised with Mendelian genetics, and this was an achievement of the period from the late 1920s to the 1950s, vital contributions to which were made by the English statistician R.A. Fisher, a eugenicist and a devout Christian who saw biological progress as evidence of God’s active and continuing role in nature, and whose centenary in 1990 was not a significant media event.

You could point out that Darwin would have been regarded as a very great naturalist and considerable geologist even if he had not published the Origin, given the extent and meticulousness of his work on, among other things, barnacles, coral reefs and volcanic islands, insectivorous and climbing plants, the sex life of orchids, the role of earthworms in making vegetable mould, domesticated plants and animals, the expression of animal and human emotions, and polymorphic botanical species (about which Darwin said that nothing in his scientific life ‘has given me so much satisfaction’). All of these have been pushed far into the background in the current celebrations. You could also say that a lot more was going on in the Origin than the versions of ‘natural selection’ celebrated by present-day evolutionists and their fan clubs. And that too would be correct. The voices of historians of science have been scarcely audible in Darwin Year, sometimes organising their own conferences, more often being wheeled onstage by those with other agendas, like ‘attendant lords … to swell a progress, start a scene or two … Deferential, glad to be of use.’

If you were historically minded, you might find it interesting that while the first-year sales of the Origin were good – 1250 copies of the first printing (sold out to the trade on day one) and 3000 of the rapidly produced 1860 second edition – books offered for sale by the publisher John Murray at the same time included 7600 copies of an account of the Arctic explorer Sir John Franklin and 3200 copies of Samuel Smiles’s Self-Help. From 1860 to 1865, the monthly sales of ‘the book that made the modern world’ were less than 30, although a cheap edition of the Origin pushed its total British sales to 16,000 by the mid-1870s. ‘Considering how stiff a book it is, this is a large sale,’ Darwin noted. That said, Vestiges had sold 24,000 copies by the time Origin appeared; Darwin’s 1881 volume on earthworms was a much greater initial publishing success than the Origin; and 60,000 copies of the natural theological tracts making up the Bridgewater Treatises – whose design argument Darwin sought to destroy – had been sold between 1833 and 1860.

You might also observe that the historical Origin, as opposed to either the modern textbook cut-and-paste version or its celebrated ‘essence’, advanced natural selection as one, admittedly powerful, engine of organic change, but also quite explicitly allowed for the role of the ‘direct action’ of the ‘external conditions of life’ and the inherited ‘effects of use and disuse’ (i.e. what are commonly called ‘Lamarckian’ forces), and what Darwin called the ‘laws of growth’ (or developmental constraints causally connecting changes in one part of an organism to another part): ‘I am convinced,’ Darwin wrote, ‘that natural selection has been the main but not the exclusive means of modification.’

A man regarded in 2009 as an avatar of atheism had originally intended to become a clergyman and, even after he had fallen away from any semblance of Anglican orthodoxy, agreed with the Reverend Charles Kingsley and the Reverend William Whewell, master of Trinity College, Cambridge, that it was just as ‘noble’ a conception of God that he worked through divinely instituted natural laws as that he used his powers directly to create each species. Four years after the Origin appeared, Kingsley wrote that ‘God’s greatness, goodness and perpetual care I never understood as I have since I became a convert to Mr Darwin’s views.’ Darwin insisted that he saw no good reason why evolution by natural selection ‘should shock the religious feelings of anyone’. Nor do those now using Darwin to power up secularism have much time for the historical figure whose funeral at Westminster Abbey was the occasion for the archdeacon to praise Darwin for having read ‘many hitherto undeciphered lines in God’s great epic of the universe’. Disbelief, Darwin wrote, eventually ‘crept over’ him, but that disbelief is less accurately categorised as atheism than as an unstable mix of agnosticism and a robust form of deism not uncommon among clerics of the Victorian Church of England. Even in America, many late 19th-century Protestant theologians had no great problem reconciling evolution with a rational and purified Christianity. (The strong assimilation of human beings and their mental capacities to the animal model was a sticking point for many – but then it still is.) Nor was biblical fundamentalism nearly as much a feature of Victorian opposition to Darwin as it is of the early 21st century. There are almost certainly more ‘young earth creationists’ – those claiming that the world was created in exactly six 24-hour days somewhere between 5700 and 10,000 years ago – among the educated and semi-educated classes now than there were in Darwin’s time.

The historical Darwin is only a spectral presence at his own commemoration. The Origin as a complex literary and scientific performance was not a focus of the global festivities, nor was Darwin’s own understanding of what he had and had not done, still less the full range of his scientific concerns. What has just been celebrated is not the historical specificity of a mid-19th-century text, or the Victorian author of works on earthworms, orchids and insectivorous plants, but the founding of a particular intellectual lineage, a lineage that led from 1859 to some version of the gene-theory-augmented ‘modern evolutionary synthesis’ that is valued today. Darwin did not discover or invent modern evolutionary biology and its intellectual fellow travellers; at most, he was at one end of a genealogy whose latest members he would scarcely have recognised.

There’s no need to be pedantic about this. If what has happened has only something to do with the historical Darwin, it has a lot to do with us, and what some of us choose to construe and to celebrate as present-day ‘Darwinism’. Those are considerable facts in their own right. A phenomenon as widely dispersed as the Darwin commemorations is bound to have had many causes, serving many purposes. ‘Every age moulds Charles Darwin to its own preoccupations, but the temptation is hard to resist,’ Philip Ball noted in the Observer. ‘In the early 20th century, he became a prophet of social engineering and the free market. With sociobiology in the 1970s, Darwinism became a behavioural theory, while neo-Darwinist genetics prompted a bleak view of humanity as gene machines driven by the selfish imperatives of our DNA.’

One inescapable present concern is, of course, the resurgence of biblical fundamentalism. Polls and attitude surveys can give you all sorts of results depending on how the questions are phrased and posed, but in 2008 a Gallup poll found that 44 per cent of US adults accepted that ‘God created human beings pretty much in their present form at one time within the last 10,000 years or so,’ while only 14 per cent agreed that ‘human beings have developed over millions of years from less advanced forms of life, but God had no part in this process.’ America is at one extreme among developed countries – 62 per cent of Egyptians and 73 per cent of South Africans seem never to have heard of Darwin or his theory – but Britain too has many doubters: Dawkins has claimed that four in ten Britons believe in creationism, though in June 2009 a British Council survey less alarmingly found that nearly a quarter of Londoners were creationists while a little less than half agreed that there was enough scientific evidence to support Darwin’s evolutionary theory. It isn’t clear, however, what that response means in light of the finding that only 45 per cent of British adults claimed to have heard of Darwin and to know ‘at least a little’ about his theory.

The centre of gravity of Darwin Year has been a celebration of secularism, a crusade against rampant religiosity and ‘public ignorance of science’. Darwin has been figured as the Scourge of the Godly. The National Secular Society notes that ‘Darwin’s 200th birthday has become a rallying point for scientists opposing creationism.’ ‘Is it important to celebrate Charles Darwin today?’ the Independent asked, answering that ‘Darwin’s legacy is threatened by proponents of creationism. By commemorating him we defend it … No advance has so upended our worldview since the realisation that the world was not flat’ – a claim that sits awkwardly alongside complaints about the limited grip of Darwinism on modernity’s collective ‘worldview’. Dawkins, who has led the troops out of the trenches in the war against scientific ignorance and religious credulity, has a wonderfully tautological answer for that: Darwin is ‘controversial among people who don’t know anything, but if you talk to people who are actually educated, he’s not really controversial’. And: ‘In order not to believe in evolution you must either be ignorant, stupid or insane.’ In Dawkins’s The God Delusion (2006), Darwin’s own stated agnosticism wasn’t nearly good enough: the Old Testament God – one of the ones who don’t exist – is famously described as ‘a misogynist, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochist, capriciously malevolent bully’. ‘My dream’, Dawkins said, was that his own work ‘may help people to “come out” as atheists’. Presiding over Channel 4’s The Genius of Charles Darwin, Dawkins recruited the great agnostic naturalist as a paladin of atheism, in theology as in science less like the historical Darwin than like Dawkins himself.
