Accidents of life

Darwinian theory was the best idea of all time, but why did it take so long to evolve? And what if w

If you have overdosed on Darwin this anniversary year, the great man himself is partly to blame: he was inconsiderate enough to publish On the Origin of Species when he was exactly 50. The resulting coincidence of sesquicen­tennial with bicentennial was bound to excite the anniversary-tuned antennae of journalists and publishers. Anniversaries are arbitrary, of course, dependent on the accident of our having ten fingers. If we had evolved with eight instead, we would have to suffer centenaries after only 64 (decimal) years, and style gurus would prate about the changing fashions of octaves instead of decades.

Incidentally, it is not far-fetched that we might have evolved a different number of fingers. The pentadactyl limb (five digits on each) has become a shibboleth of vertebrate zoology, and even animals such as horses (which walk on their middle fingers and toes) or cows (two digits per limb) have lost the extra digits from a five-fingered ancestor. But the lungfish-like group of Devonian fishes from which all land vertebrates are descended included species with seven (Ichthyostega) or eight (Acanthos­tega) digits per limb. If we were descended from Acanthostega, instead of from an unsung five-fingered cousin of the same fish, who knows what feats of virtuosity pianists might now perform with 16 fingers? And would computers have been invented earlier, because hexadecimal arithmetic translates more readily than decimal into binary?

Historical accidents of this sort are rife, contrasting with the illusion of good design to provide some of our most convincing evidence that evolution happened. Sometimes the legacy of history goes beyond arbitrary accidents, and spills over into downright poor design. The vertebrate retina is installed backwards, facing away from the light, which perforce has to pass through a carpet of nerves on their way to the "blind spot" where they dive through the retina, bound for the brain. In spite of this we see tolerably well, because natural selection is good at cleaning up after its bodges. But an engineer who produced such a travesty of design would be fired instantly. The retina is a legacy of remote history.

For whatever reason lost in some Devonian swamp, our ancestors evolved with ten fingers. And that is why Darwin was exactly half a century old when he published the book that set us on the path to understanding the whole of life - its diversity, complexity, beauty, compelling illusion of design, and every detail such as why we have the eyes, fingers and toes that we do.

Mysterious gap

But why did Darwin wait until he was 50 before publishing his great idea (the best idea anyone has ever had, according to the distinguished philosopher Daniel Dennett)? The idea of natural selection came to Darwin more than two decades earlier, in 1838. He wrote out a pencil sketch of it in 1842, then a fuller version in 1844, which he asked his wife Emma to publish if he should die. Then nothing: the mysterious gap. If you were a young man of 30, in possession of the best idea anyone had ever had, would you sit on it until you were 50?

When Darwin eventually did write On the Origin of Species, he was jolted into it by another travelling naturalist, Alfred Wallace, who had the same brilliant idea in 1858. Again in an accident of history, Wallace, who was recovering from a malarial fever on the Indonesian island of Ternate, chose to send his manuscript to - of all people - Charles Darwin.

A potential priority dispute was averted by the gentlemanly behaviour of both protagonists and the smooth diplomacy of Charles Lyell and Joseph Hooker. These elder statesmen of science arranged for Wallace's and Darwin's papers to be read, in their absence, at the Linnean Society in London in 1858, where the great idea fell completely flat and was ignored by all. We remember Darwin more than Wallace because he wrote the book, published in 1859, which fell anything but flat and revolutionised our world for ever.

Hypotheses to explain Darwin's delay range from "He didn't want to upset his pious wife" to "He wanted to get all his ducks in a row before the shooting began", and there may be truth in both. But I remain mystified by the larger question of why humanity as a whole waited until the 19th century. On the face of it, any one of Newton's achievements - optics, gravity, the laws of motion, the differential and integral calculus - seem more difficult, yet Newton's annus mirabilis pre-dated Darwin by nearly two centuries. The proof of Pythagoras's Theorem, and others of Euclid's elegant compendium, pre-date Darwin by more than two millennia.

Once again, Darwin's achievement doesn't seem all that difficult. Why did it elude Aristotle? And everybody else - great philosophers, mathematicians, anatomists, thinkers and achievers of all kinds down the centuries? Why did this simple but staggeringly powerful idea have to wait until the middle of the 19th century before bursting into our consciousness through the medium of two Victorian naturalists? And why, even today, do so many people have difficulty grasping it?

So, what is this best of all ideas, the idea of evolution by natural selection? It is really the principle of the sieve, multiplied a billionfold and applied cumulatively over billions of years. Every generation is a gene sieve (Darwin didn't put it this way, because he didn't know about genes). The genes that fall through the sieve are the minority that drop through from the current generation to the next. In order to do so, the individuals possessing them have to reproduce. And in order to reproduce, they have to survive. Surviving is difficult. There are predators waiting to pounce, diseases waiting to strike. Incompetence takes its toll in missed footfalls or unheeded signals of danger.

Reproduction, too, is an obstacle course. The individual has to find a mate, woo her with alluring feathers or smells, fight off rivals with talons or antlers, feed the young and protect them from marauders. In any generation, only a minority of individuals will become long-term ancestors. The vast majority of animals that ever lived have no surviving descendants. And the genes that jostle and jockey for position in every generation are the genes that, without a single, solitary exception, have passed through the bodies of an ancestral elite, the tiny minority who managed to become ancestors.

The genes that exist are the genes that made it through a million sieves in cumulative cascade. And what was it that made them do so well? They co-operated, through the intricate processes of embryology, with other successful genes to build an unbroken succession of elite individuals, equipped by them to become ancestors. That is why the qualities of the elite are the qualities inherited by every animal and plant: because existence is tough, and competition sorted out the ancestors from the failures

An arms race

The exact equipment for survival varies from species to species, for there are many ways to survive: streamlined wings, in the case of swallows; powerful flukes in whales and spades in moles; bewildering camouflage and mimicry in insects; shimmering tail feathers in birds of paradise. All these are the outward and visible levers that propel the genes that made them through the sieves of the generations. And, to complicate matters, the survival techniques of each species open windows of opportunity for others to exploit, as Darwin recognised.

Wherever you see elaborate and complicated machinery in a living body, it is usually the end product of an arms race, run in evolutionary time, each side accumulating improved equipment to outdo the other - an arms race between predators and prey, between parasites and hosts, even between males and females of the same species.

The modern theory of evolution by natural selection can be expressed mathematically, in a calculus of changing gene frequencies. Darwin was no mathematician and he knew nothing of genetics, but he had the essence of this great and simple idea, and he expressed it with the luminous clarity of one of the greatest minds ever to emerge from the process of evolution that he discovered.

Why Jeremy Corbyn is a new leader for the New Times

In an inspired election campaign, he confounded his detractors and showed that he was – more than any other leader – in tune with the times.

There have been two great political turning points in postwar Britain. The first was in 1945 with the election of the Attlee government. Driven by a popular wave of determination that peacetime Britain would look very different from the mass unemployment of the 1930s, and built on the foundations of the solidaristic spirit of the war, the Labour government ushered in full employment, the welfare state (including the NHS) and nationalisation of the basic industries, notably coal and the railways. It was a reforming government the like of which Britain had not previously experienced in the first half of the 20th century. The popular support enjoyed by the reforms was such that the ensuing social-democratic consensus was to last until the end of the 1970s, with Tory as well as Labour governments broadly operating within its framework.

During the 1970s, however, opposition to the social-democratic consensus grew steadily, led by the rise of the radical right, which culminated in 1979 in the election of Margaret Thatcher’s first government. In the process, the Thatcherites redefined the political debate, broadening it beyond the rather institutionalised and truncated forms that it had previously taken: they conducted a highly populist campaign that was for individualism and against collectivism; for the market and against the state; for liberty and against trade unionism; for law and order and against crime.

These ideas were dismissed by the left as just an extreme version of the same old Toryism, entirely failing to recognise their novelty and therefore the kind of threat they posed. The 1979 election, followed by Ronald Reagan’s US victory in 1980, began the neoliberal era, which remained hegemonic in Britain, and more widely in the West, for three decades. Tory and Labour governments alike operated within the terms and by the logic of neoliberalism. The only thing new about New Labour was its acquiescence in neoliberalism; even in this sense, it was not new but derivative of Thatcherism.

The financial crisis of 2007-2008 marked the beginning of the end of neoliberalism. Unlike the social-democratic consensus, which was undermined by the ideological challenge posed by Thatcherism, neoliberalism was brought to its knees not by any ideological alternative – such was the hegemonic sway of neoliberalism – but by the biggest financial crisis since 1931. This was the consequence of the fragility of a financial sector left to its own devices as a result of sweeping deregulation, and the corrupt and extreme practices that this encouraged.

The origin of the crisis lay not in the Labour government – complicit though it was in the neoliberal indulgence of the financial sector – but in the deregulation of the banking sector on both sides of the Atlantic in the 1980s. Neoliberalism limped on in the period after 2007-2008 but as real wages stagnated, recovery proved a mirage, and, with the behaviour of the bankers exposed, a deep disillusionment spread across society. During 2015-16, a populist wave of opposition to the establishment engulfed much of Europe and the United States.

Except at the extremes – Greece perhaps being the most notable example – the left was not a beneficiary: on the contrary it, too, was punished by the people in the same manner as the parties of the mainstream right were. The reason was straightforward enough. The left was tarnished with the same brush as the right: almost everywhere social-democratic parties, albeit to varying degrees, had pursued neoliberal policies. Bill Clinton and Tony Blair became – and presented themselves as – leaders of neoliberalism and as enthusiastic advocates of a strategy of hyper-globalisation, which resulted in growing inequality. In this fundamental respect these parties were more or less ­indistinguishable from the right.

***

The first signs of open revolt against New Labour – the representatives and evangelists of neoliberal ideas in the Labour Party – came in the aftermath of the 2015 ­election and the entirely unpredicted and overwhelming victory of Jeremy Corbyn in the leadership election. Something was happening. Yet much of the left, along with the media, summarily dismissed it as a revival of far-left entryism; that these were for the most part no more than a bunch of Trots. There is a powerful, often overwhelming, tendency to see new phenomena in terms of the past. The new and unfamiliar is much more difficult to understand than the old and familiar: it requires serious intellectual effort and an open and inquiring mind. The left is not alone in this syndrome. The right condemned the 2017 Labour Party manifesto as a replica of Labour’s 1983 manifesto. They couldn’t have been more wrong.

That Corbyn had been a veteran of the far left for so long lent credence to the idea that he was merely a retread of a failed past: there was nothing new about him. In a brilliant election campaign, Corbyn not only gave the lie to this but also demonstrated that he, far more than any of the other party leaders, was in tune with the times, the candidate of modernity.

Crises, great turning points, new conjunctures, new forms of consciousness are by definition incubators of the new. That is one of the great sources of their fascination. We can now see the line of linkage between the thousands of young people who gave Corbyn his overwhelming victory in the leadership election in 2015 and the millions of young people who were enthused by his general election campaign in 2017. It is no accident that it was the young rather than the middle-aged or the seniors who were in the vanguard: the young are the bearers and products of the new, they are the lightning conductors of change. Their elders, by contrast, are steeped in old ways of thinking and doing, having lived through and internalised the values and norms of neoliberalism for more than 30 years.

Yet there is another, rather more important aspect to how we identify the new, namely the way we see politics and how politics is conceived. Electoral politics is a highly institutionalised and tribal activity. There have been, as I argued earlier, two great turning points in postwar politics: the social-democratic era ushered in by the 1945 Labour government and the neoliberal era launched by the Tory government in 1979.

The average Tory MP or activist, no doubt, would interpret history primarily in terms of Tory and Labour governments; Labour MPs and activists would do similarly. But this is a superficial reading of politics based on party labels which ignores the deeper forces that shape different eras, generate crises and result in new paradigms.

Alas, most political journalists and columnists are afflicted with the same inability to distinguish the wood (an understanding of the deeper historical forces at work) from the trees (the day-to-day manoeuvring of parties and politicians). In normal times, this may not be so important, because life continues for the most part as before, but at moments of great paradigmatic change it is absolutely critical.

If the political journalists, and indeed the PLP, had understood the deeper forces and profound changes now at work, they would never have failed en masse to rise above the banal and predictable in their assessment of Corbyn. Something deep, indeed, is happening. A historical era – namely, that of neoliberalism – is in its death throes. All the old assumptions can no longer be assumed. We are in new territory: we haven’t been here before. The smart suits long preferred by New Labour wannabes are no longer a symbol of success and ambition but of alienation from, and rejection of, those who have been left behind; who, from being ignored and dismissed, are in the process of moving to the centre of the political stage.

Corbyn, you may recall, was instantly rejected and ridiculed for his sartorial style, and yet we can now see that, with a little smartening, it conveys an authenticity and affinity with the times that made his style of dress more or less immune from criticism during the general election campaign. Yet fashion is only a way to illustrate a much deeper point.

The end of neoliberalism, once so hegemonic, so commanding, is turning Britain on its head. That is why – extraordinary when you think about it – all the attempts by the right to dismiss Corbyn as a far-left extremist failed miserably, even proved counterproductive, because that was not how people saw him, not how they heard him. He was speaking a language and voicing concerns that a broad cross-section of the public could understand and identify with.

***

The reason a large majority of the PLP was opposed to Corbyn, desperate to be rid of him, was because they were still living in the neoliberal era, still slaves to its ideology, still in thrall to its logic. They knew no other way of thinking or political being. They accused Corbyn of being out of time when in fact it was most of the PLP – not to mention the likes of Mandelson and Blair – who were still imprisoned in an earlier historical era. The end of neoliberalism marks the death of New Labour. In contrast, Corbyn is aligned with the world as it is rather than as it was. What a wonderful irony.

Corbyn’s success in the general election requires us to revisit some of the assumptions that have underpinned much political commentary over the past several years. The turmoil in Labour ranks and the ridiculing of Corbyn persuaded many, including on the left, that Labour stood on the edge of the abyss and that the Tories would continue to dominate for long into the future. With Corbyn having seized the political initiative, the Tories are now cast in a new light. With Labour in the process of burying its New Labour legacy and addressing a very new conjuncture, then the end of neoliberalism poses a much more serious challenge to the Tories than it does the Labour Party.

The Cameron/Osborne leadership was still very much of a neoliberal frame of mind, not least in their emphasis on austerity. It would appear that, in the light of the new popular mood, the government will now be forced to abandon austerity. Theresa May, on taking office, talked about a return to One Nation Toryism and the need to help the worst-off, but that has never moved beyond rhetoric: now she is dead in the water.

Meanwhile, the Tories are in fast retreat over Brexit. They held a referendum over the EU for narrowly party reasons which, from a national point of view, was entirely unnecessary. As a result of the Brexit vote, the Cameron leadership was forced to resign and the Brexiteers took de facto command. But now, after the election, the Tories are in headlong retreat from anything like a “hard Brexit”. In short, they have utterly lost control of the political agenda and are being driven by events. Above all, they are frightened of another election from which Corbyn is likely to emerge as leader with a political agenda that will owe nothing to neoliberalism.

Apart from Corbyn’s extraordinary emergence as a leader who understands – and is entirely comfortable with – the imperatives of the new conjuncture and the need for a new political paradigm, the key to Labour’s transformed position in the eyes of the public was its 2017 manifesto, arguably its best and most important since 1945. You may recall that for three decades the dominant themes were marketisation, privatisation, trickle-down economics, the wastefulness and inefficiencies of the state, the incontrovertible case for hyper-globalisation, and bankers and financiers as the New Gods.

Labour’s manifesto offered a very different vision: a fairer society, bearing down on inequality, a more redistributive tax system, the centrality of the social, proper funding of public services, nationalisation of the railways and water industry, and people as the priority rather than business and the City. The title captured the spirit – For the Many Not the Few. Or, to put in another way, After Neoliberalism. The vision is not yet the answer to the latter question, but it represents the beginnings of an answer.

Ever since the late 1970s, Labour has been on the defensive, struggling to deal with a world where the right has been hegemonic. We can now begin to glimpse a different possibility, one in which the left can begin to take ownership – at least in some degree – of a new, post-neoliberal political settlement. But we should not underestimate the enormous problems that lie in wait. The relative economic prospects for the country are far worse than they have been at any time since 1945. As we saw in the Brexit vote, the forces of conservatism, nativism, racism and imperial nostalgia remain hugely powerful. Not only has the country rejected continued membership of the European Union, but, along with the rest of the West, it is far from reconciled with the new world that is in the process of being created before our very eyes, in which the developing world will be paramount and in which China will be the global leader.

Nonetheless, to be able to entertain a sense of optimism about our own country is a novel experience after 30 years of being out in the cold. No wonder so many are feeling energised again.
