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.

The fish-eaters and the fasters

With a population split between whites and Asian Muslims, in some ways Nelson in Lancashire feels like similar-sized towns in Ulster: two communities separated by a gulf of non-communication.

In the late afternoon of local election day this month, the chairman of Nelson Town Council was working the terraces of old cotton weavers’ houses on his patch. Sajid Ali was wearing a red rosette and a navy blue cardigan over his capacious white shalwar kameez, and what looked like his dancing shoes.

This was not the forlorn ritual of unanswered doors, blank looks and curt responses habitually experienced by Labour canvassers even in more promising political times. Along these streets Sajid is a figure of some consequence: a jolly fellow and, as one opponent put it, an “interesting character”.

Almost everyone was in; Sajid knew almost all of them; and they in turn understood what was required. Sometimes a quick burst of Lancy Punjabi did the job: “Salaam alaykum, yoong maan, how yer doing? What time yer coomin’ to vote?” To older voters his spiel would be entirely in Punjabi and the response would often be a head-wobble, that characteristic south Asian gesture, which, when given to Westerners, can be baffling, but in these cases clearly signified solid intention.

The Labour candidate in the Brierfield and Nelson West division of Lancashire County Council, Mohammed Iqbal, held his seat comfortably on the day his party lost control of the county. And he did so on a poll of 58 per cent: a far higher turnout than in any of the other, whiter areas of Pendle; the highest in Lancashire; and higher than wards with these demographics would usually expect even at a general election. The average across Lancashire on 4 May was 37 per cent. It seems reasonable to conclude that the votes from those of ­Pakistani heritage, marshalled by Sajid, were wholly responsible.

Nelson is a strange, sad, divided, forgotten old cotton town, not without beauty. The weavers’ houses are stone not brick, which, elsewhere, might make them rather chic. A few minutes from town is wonderful Pennine countryside, and to the north the view is dominated by Pendle Hill itself, brooding like some sleeping sea monster.

Pendle is both the borough council and the constituency, where the mix of urban and rural has delivered it to the winning side in seven of the eight general elections since its creation 34 years ago. (Labour took it, five years prematurely, in 1992.) No one seriously believes the 5,400 Tory majority is in play. Nonetheless, Nelson can explain a lot about British politics in 2017.

“This was a cracking town,” said John Bramwell (“John the Fish”), who has been purveying cod, haddock and non-stop banter to Nelson for 41 years, first on the market, now from one of the last white-run, independent shops in the town centre. Nelson had a football team that played fleetingly (1923-24) in the old Second Division, what is now called the Championship. And in 1929 the Lancashire League cricket team, flashing cash in a manner that baffled the national press, signed Learie Constantine, the most gifted and thrilling West Indian all-rounder of his generation.

“When he arrived, no one in Nelson had ever seen a black man close-to,” said Derek Metcalfe, the club’s historian. “People would cross the road when he passed by. But he grew into their affections. He was a highly intelligent man as well as a great player.” Constantine, after a post-cricket career in the law, Trinidadian politics and diplomacy, finished life in the House of Lords as Baron Constantine of Maraval and Nelson, Britain’s first black peer. In July 1943 the Imperial Hotel in Bloomsbury accepted his booking but not his presence, and he promptly sued. His victory at the high court the following year was an early landmark in the fight against racial discrimination.

It was the 1950s before Nelson would get used to seeing non-white faces again, when the mill owners, battling labour shortages and overseas competition, turned to Pakistan to find biddable and affordable workers. They found them in Gujrat District, which is not one of the more worldly places, even in the rural Punjab.

“The first group were young men who in many ways integrated better than they do now. There were no mosques. They went to the pubs with their workmates and knocked around with local women. Then they had to go to the airport to collect the intended wives they hadn’t met yet,” recalled Tony Greaves, the Liberal Democrat peer who is deputy leader of Pendle Borough Council.

The mills disappeared, gradually but inexorably, but the Pakistani community kept growing and has now reached its fourth generation. The young men do not normally spend time in pubs; indeed, in a town of 30,000 people, there are only two left, plus a couple on the outskirts. It is hard to imagine anywhere that size in Britain with fewer. There are, however, at least a dozen mosques. The 2011 census recorded 40 per cent of the population as Asian, but on market day in the town centre the proportion seems much higher. The most prominent retail outlets are two bazaars: the Nelson (the
old Poundstretcher) and the Suraj opposite (the old Woolworths). Few white faces are seen in either: the saris and hijabs are beautiful but of little interest. They are all imported to this textile town from south Asia.

The white people have retreated, either out of the town altogether or to the semis of Marsden, on the hill. In the visible life of Nelson, they are clearly a minority. Population change on this scale can be accommodated, if not always easily, in large cities. It is a different proposition in a small town that was once tight-knit and, despite its closeness to larger places such as Blackburn, Accrington and Burnley, largely self-contained.

Even after 60 years, hardly anything has melted in the pot. The early migrants were villagers who placed little value on education. Recent history has led Muslims all over the world to turn inwards, to their own religion and culture. This is being exacerbated by white flight and by the advent of religious free schools, a disaster for anywhere in search of cohesion. The old Nelsonians have turned away. “Nelson is not multiracial or multicultural. It is biracial and bicultural,” says Greaves. “I would love to tell you that I go round to Abbas’s house to have chicken jalfrezi and he comes to mine for steak pudding and chips,” says John the Fish. “It’s just not like that.”

Unemployment is high at 18 per cent; there is no shortage of taxis. Educational attainment is patchy. Teachers at the two high schools fear their best pupils will be creamed off further by the promised grammar-school boom.

The vicar of Nelson, Guy Jamieson, and at least some of the local imams do their utmost to make connections between the communities. In certain respects Nelson feels like similar-sized towns in Ulster: two communities separated by a gulf of non-communication. In other ways, this description is unfair. When Burnley, just four miles away, suffered riots in 2001, Nelson stayed quiet. I could sense no threat, no active tension, merely resigned indifference on both sides. “There’s a poverty of confidence,” Jamieson said. “They don’t know how to sit down and engage.”

***

A modern English town council, subordinate to Brussels, Westminster, county and district, is an improbable power base, but Sajid Ali seems to be making Nelson’s work. Its precept is only £330,000 a year but this is not capped, so it suits both district and town if Pendle offloads smaller assets: parks, play areas, community centres. It is a minimalist form of devolution, but harks back to the days when Nelson was a borough in its own right, and looks forward to an improbable future when our towns might again be allowed to take their own decisions as they do in more grown-up countries.

But the council votes on party lines, Labour’s 16 councillors trumping the Tories’ eight. “They won’t work with us,” Sajid says flatly. “They don’t run it fairly for the town itself,” says the Conservative Neil McGowan. “If we put something forward for Marsden, we are always outvoted. One council official told me they’d never come across a town like it.” In Tony Greaves’s words, “The
politics in Nelson were always sour.” In the 1930s it was known as Little Moscow.

When I first met Sajid, however, he was outside a polling station doing a stint as a teller and laughing merrily along with his blue-rosetted counterpart, Arshad Mahmood. Yet things were not quite as they seemed. Mahmood was part of a mass defection of Pakistani Lib Dems to the Conservatives which appears to have nothing to do with Brexit, extra taxes for the NHS or Maymania. What it does have to do with remains elusive even to local politicians: “clan politics” and “personal ambition” were mentioned. It may be even more complicated than that. “So you’ll be voting for Theresa May next month?” I asked Mahmood. “Oh, no, I like Jeremy Corbyn. Very good policies.”

Perhaps this helped Sajid maintain some enthusiasm for the bigger campaign ahead, though he was daunted by one fact: the general election coincides with Ramadan, and dawn-to-dusk fasting comes hard in these latitudes when it falls in summertime. Still, he was impressed by all the new members Corbyn had brought to Labour: “The way I see it is that each new member has five, ten, 15, 20 people they can sell the message to.”

This seemed a bit strange: it implied he thought politics in the rest of Britain worked as it did in these streets. He had boasted earlier that he knew everyone. “All over Nelson?” “Oh, no,” he had backtracked. “In the English community nobody knows their next-door neighbour.” Which was an exaggeration, but perhaps not much of one.

There were no posters along Sajid Ali’s streets – not one. The information about which house to choose was on the canvass return and, more significantly, in his head. Just once he got it wrong. A little white girl opened the door and then a tattooed, muscular figure in a singlet barrelled towards the door. He wasn’t aggressive, just brisk. “Naaw. I doan’t vote.” End of. It was a sudden reminder of the norms of modern British politics.

***

Another norm is that, at any local count, no one ever thinks much of the big picture. The rise and fall of prime ministers, earthquakes and landslides are no more than distant rumours, of surprisingly little interest to the principals; what matters is the here and now. Where did that ballot box come from? How big is the postal vote? Any chance of a recount? When the five seats for Pendle were counted the next day at the leisure centre in Colne, one stop further up the clanking branch line from Nelson, no one was talking about the Tory takeover at County Hall.

Here there was something for everyone: Mohammed Iqbal won, just as Sajid predicted. Azhar Ali took the other Nelson seat even more easily for Labour. Both results were greeted with more effusive male hugs than would be considered seemly in Berkshire. In Pendle Central the Tories knocked out the sitting Lib Dem, but – heroically, in their eyes – one of the Lib Dem candidates grabbed a seat in the rural division.

But the most interesting result came in the most trifling contest: a twinned by-election for two vacancies in Nelson Town Council’s lily-white ward of Marsden, so electors had two votes each. The seats were won by a Conservative married couple, the Pearson-Ashers, who got 426 and 401; the single BNP candidate had 359 votes, with one Labour candidate on 333 and the other on 190. The first of these was called Laura Blackburn; the second Ghulam Ullah. This suggests a good deal of vote-splitting that Labour might find rather unpalatable.

In fact, Marsden already has one far-right relic: Brian Parker, who sits on Pendle Borough Council, is the last survivor in the top two tiers of local government of the BNP mini-surge that took them to 55 council seats across the country by 2009. Of Parker, two opposing councillors told me: “He’s actually a very good ward councillor.”

Curiously, Ukip has made little impact in Nelson or in Pendle as a whole. So there is not much scope for the party to fulfil what appears to be its immediate destiny: as a way station for Labour’s historic core voters to catch their breath on the arduous journey into Theresa May’s arms. According to John the Fish, whose shop functions as a kind of confessional for white opinion, they may no longer need a stopover: “I’m getting plenty of people, staunch Labourites, telling me they can’t stand Corbyn.”

I asked him how many Pakistani regulars he had. He broke off from chopping hake and held up five fingers. On 8 June the fish-eaters of Marsden can be expected to rouse themselves more energetically than the Ramadan fasters across town.

***

Seedhill, the cricket ground graced by Constantine, is pretty Nelson rather than gritty Nelson, even though a chunk of it, including the old pavilion, was lopped off years ago to form an embankment carrying the M65. Upstairs in the pavilion is a wonderful picture of the great man, eyes ablaze, down on one knee for a full-blooded cover-drive. It would have made a better monument in the town centre than the 40-foot weaving shuttle that has dominated Market Street since 2011. I thought it was a torpedo; children think it’s a giant pencil.

The packed houses that watched Constantine lead Nelson to seven league titles in nine years have dwindled now: there were only a couple of dozen to watch his successors play Accrington recently. But it was a drab day with a chilly breeze and Burnley were at home to West Brom in the winter game down the road.

And generally the club thrives better than the town. Given the lack of hotels and pubs, the pavilion is much in demand for functions, and the team remains competitive. Nelson fielded four local Asians for the Accrington match, which suggests that, in one activity at least, integration is just about where it should be.

It seems unlikely that a similar situation would apply at the crown green bowls or the brass band, or any other of the long-standing recreations in Nelson (though small but growing numbers of Pakistanis are now taking allotments). The knee-jerk liberal reaction might be that this is somehow the fault of the white Nelsonians. I think this attitude is a grave oversimplification that has done much damage.

In one respect the incomers have re-created the old life of Nelson. In the hugger-mugger stone-built terraces, the neighbourliness, the power of extended families, the external patriarchy and the internal matriarchy, the vibrancy, the sense of communal struggle . . . that is exactly what this cotton town must have been like a century ago.
