Not just red in tooth and claw: biology's big debates

In the second of a series, biologist and priest, Andrew Davison, examines why it’s important to keep up with biology’s big debates.

Andrew works at the intersection of theology, science and philosophy. He is Canon and Regius Professor of Divinity at Christ Church, Oxford.

There’s hardly been a livelier time for evolutionary science than today; indeed, passions can run high. It’s not that Darwin’s vision of evolution is fundamentally in doubt: species adapt by natural selection, there’s variation between individuals, and those better adapted for their environment survive more often, passing on their genes to their children. In that, the theory of evolution stands, but many other parts of the evolutionary picture from the second half of the twentieth century are coming under criticism. That includes the following maxims:  

‘the only significant form of inheritance involves genetic code’, 

‘nothing that happens to an organism during its lifetime is passed on to its progeny’,  

‘we agree what we mean by “species”’,  

‘genes pass down the branches of the tree of life, not between them’,  

and ‘evolution is fundamentally all about competition, not cooperation’. 

Among the excellent crop of writers on these themes, Eva Jablonka and Marion Lamb stand out for their elegant prose, and a gift for communicating complex ideas clearly. As they recognise, the standard mid-twentieth century model of evolution might be worth criticising, but it’s also landed all sorts of important basic points. (They list ten.) The shortfall of the earlier, dominant theory was in being too narrow, with each insight too quickly eclipsing others.  

Here are two examples. First, the classic twentieth century picture saw inheritance in terms of DNA and genes, passed on by ‘germline’ cells, such sperm and pollen. That’s all true, but it shouldn’t restrict our wider view of inheritance to that. Today, writers such as Jablonka and Lamb stress that organisms inherit from their parents (or parent) in all sorts of ways.  

A second plank of the twentieth century picture is that evolution involves descent from a common ancestor. Again, that says something vital, even central, accepted by evolutionist old and new. The twentieth century position, however, added a restriction: that’s all that’s important on this score. The newer perspective recognises that while genes are – of course – central, and passed on from parent to child, organisms also swap genes between themselves (between branches of the tree of life, not just along those branches), even between very different species. 

If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

There’s a lot of excitement around these sorts of claims (and, remember, Jablonka and Lamb make eight more), and that can get quite noisy. Defenders of the older, narrower picture typically say that the newer themes are simply fuss over minor points. Advocates of the newer perspective disagree, saying that the twentieth century picture risks missing some important features of biology, which are now coming into better focus. 

Why such debates matters 

Why might this ferment among biologists matter for a site like this one, and for theologians, and discussions of religious matters? Well, for one thing, as I pointed out in my previous article, nothing quite dissolves the supposed animosity between science and religion (which is, after all, a relatively recent invention) like theologians and religious people getting excited about biology. It’s also important that any humanities scholar, the theologian among them, who’s engaging with science should keep up to date. If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

But there’s more at stake. As we have seen, the twentieth century picture, for all it brought an admirable clarity to evolutionary thought, was reductionistic. We see that in Jablonka and Lamb’s exhortation to scientists: ‘yes, stress x, but don’t think that means you have to deny y.’ A religious vision tends to be an expansive one. It wants to recognise the reality and value of all sorts of things. Yes, there’s matter, atoms, molecules, and genes, but there’s also organisms, agents, cultures, groups, economies, hopes, loves. They’re all real. We can’t reduce one to the other: not organisms to genes, or agents to economies. A turn from reduction is welcome. 

More than that, almost everything in the emerging twenty-first century view of evolution is fascinating from a theological perspective.  

Take convergence, for instance. It turns out that evolution isn’t just driven by randomness, or by the demands of the surroundings. Also important are various features of physics, or mathematics – the contours of reality – that throw up elegant solutions to evolutionary problems, which are adopted by evolution time and again. Wherever you need to sturdy and space-efficient packing of cells (as in a honey comb, or a a wasp’s nest), the hexagon is ready and waiting.  Wherever there’s water or air to navigate, the laws of fluid dynamics are bound to throw up wings, and bodies shaped like fish, dolphins, and penguins (which are all quite similar in shape).  

How do we know this? Because evolution has converged on wings and that body shape independently, many times, as also on eyes, and everything else that Simon Conway Morris lists in the nine closely printed columns of convergences in the index to his book Life’s Solution. Evolution certainly involves randomness and need, but alongside them is something more like Plato’s forms: timeless realities, there to be discovered and put to work. Among the more theological of these eternal verities, covered in Conway Morris’s book, are perception, intelligence, community, communication, cooperation, altruism, farming, or construction 

 Exceeding a zero-sum game 

Then there’s cooperation. Ever since Darwin’s Origin was published, and, even more, ever since Tennyson wrote about nature ‘red in tooth and claw’, theologians have been embarrassed about the place of cooperation in their vision of the world. Now, however, it turns out, competition isn’t the only force at work in biology or evolution after all. One of the features of reality that evolution discovers and puts to work again and again is cooperation, and ways to exceed a ‘zero-sum’ game. We see that in cooperation within a species, but also in cooperation between species, which is ubiquitous in nature: called mutualism, it’s found everywhere. As a rule, once two species stick around in proximity for the long run, down many generations, their relationship will turn to mutual benefit.  

Ethicists are often wary of the suggestion that we can look at the way things are, and read a moral code there (getting an ‘ought’ from an ‘is’), but it’s an unusual person whose vision of right and wrong isn’t shaped, to some degree, by a sense of what the world is like. Well, it turns out that nature bears witness to the enduring worth of cooperation, and not only to competition.   

In the first of these articles on biology, I pointed out the significance of ethics in thinking about biology, and about evolution in particular. For better or worse, and often for worse, thinking about evolution has been an ethical, social, political story. The evolutionary has been put to work for immoral, ends. It turns out to be wrong twice over to suppose evolution commends only competition. It’s wrong, first of all, because we are rational creatures, who can aspire to an understanding of good and evil that transcends the realm of nature. But also, as we now see, it’s wrong even to suppose the nature is only red in tooth and claw. There’s competition, but there’s also a lot of cooperation.

Are we Secular, Christian or Pagan?

After the Paris Olympics, Graham Tomlin wonders whether a full-on secularism could veer back towards a modern paganism.

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

Nicola Olyslagers is an Australian high jumper who recently won silver at the Paris Olympics. Gearing herself up for one of her final jumps, she lifted her hands and eyes to the heavens at which point the BBC commentator said: ‘and so, she looks to the gods for help as she prepares to jump’.  

All very dramatic. Except that is exactly what she was not doing.  

Olyslagers is a devout Christian. She found her faith aged 16, and regularly speaks of it in public. Her pre-jump routine was not a prayer to the gods of the pagan pantheon, an appeal for a slice of luck or good fortune, but a prayer to the God of Jesus – a commentator who had done their homework might have been expected to know that.  

In such a public display of devotion, she is far from alone. A feature of this Olympics is the number of athletes who have worn their faith on their sleeves, from Adam Peaty to Gabriel Medina, in the most famous surfing photograph of the games. Every night you see someone thanking God, crossing themselves, advertising their faith – not mainly as a plea for victory, but as Ashley Null points out elsewhere on Seen & Unseen as a way of handling the ups and downs of elite sport. 

When you place these public professions of Christian faith next to the row over the opening ceremony, it raises an interesting question. During that ceremony, Christians around the world were upset at what looked like a parody of the Last Supper. Olympics organisers then claimed that the offending scene was not intended to mock the heart of Christian worship but was a reference to Dionysius and the feast of the pagan gods, connecting the modern Olympics with its roots in the pagan world of the classical period. 

If it was a reference to Dionysian pagan feasting, the opening ceremony was perhaps a more telling sign of the direction of our culture than we might think, and one that might cause Christians even more concern than a second-rate mockery of the Last Supper. Because it clarifies a choice that our culture might face as our era proceeds.

In 1939, on the eve of the Second World War, T.S. Eliot gave a series of lectures in the refined setting of Corpus Christi College Cambridge, which were eventually published as The Idea of a Christian Society. In it, he laid out a stark prognosis:

“The choice before us is between the formation of a new Christian culture, and the acceptance of a pagan one."

Eliot thought that his society was neither fully Christian, nor fully pagan, but ‘neutral’. Yet he feared that could not last long. Such ‘political liberalism’ was in danger of fostering its own demise by an indiscriminate refusal to make moral value judgments and decide between versions of the good. As he watched the rise of fascism in Europe, which stood on the verge of the most destructive war in its history so far, he made a significant claim: that the only alternative to what he saw as a pagan totalitarianism was a Christian society. 

Closer to our times, a similar thought has occurred to other influential figures. The feminist writer Louise Perry recently mused over the idea that our society is re-paganising, citing the moral conundrum over modern abortion. Despite not being a practising Christian, she sees abortion bearing uncomfortable similarities to pagan infanticide, a sign that we are heading back to a moral scheme with a strong likeness to pagan valuations of human life. The Jewish feminist writer Naomi Wolf has done the same, in an extraordinary essay. Despite a tendency to veer into conspiracy theories too easily, she makes a compelling case that as the Jewish-Christian ethos that underpinned western society has receded, what has emerged is not a benign neutrality, but dark powers that used to lurk in the background of Old Testament religion:  

“the sheer amoral power of Baal, the destructive force of Moloch, the unrestrained seductiveness and sexual licentiousness of Astarte or Ashera — those are the primal forces that do indeed seem to me to have returned… or at least the energies that they represent — moral power-over; death-worship; antagonism to the sexual orderliness of the intact family and faithful relationships — seem to have ‘returned,’ without restraint.” 

The Nazism to which Eliot referred, as we now know, was a dead end - literally. We console ourselves today with the thought that we have left such extremes behind, that the idolatries of fascism and communism were defeated in 1945 and 1989 respectively, and that we now inherit a secular liberal democratic space which is happily neutral and keeps the peace between different claims to truth – an advance on either paganism or Christianity. 

That may be true, but as Rowan Williams pointed out, there is a difference between ‘procedural secularism’ – a non-dogmatic role for the state in helping keep equilibrium in a society where there is no common agreement on truth, and ‘programmatic secularism’, which imposes a distinct set of values on society which tend to inhibit religious expression and denies anyone the right to claim their religious perspective is ultimately true. 

The makers of the Olympic opening ceremony, without a trace of irony, justified their creation by saying that it was celebrating French Republican ideas of inclusion, freedom, human rights and so on – the liberty, fraternity and equality of the French Revolution, which was in turn, born out of the French Enlightenment. This was full-on programmatic secularism on display. It was a classically libertarian view of freedom, the absolute freedom to choose what we do with our lives, of individual self-expression, with no overarching, universal idea of the Good, which of course is one particular understanding of what freedom means. It is distinct, for example, from an older view of freedom as gradual liberation from (and therefore the disciplining of) some of our conflicted inner impulses that are deemed destructive of the soul or of society. Secular liberalism that parades itself as self-evident, the opinion of all right-thinking people, is so often incapable of seeing how for others - Muslims and Christians for example - it is anything but self-evident. There are many across the globe who are not content with an overarching moral scheme which insists on telling them that their belief is a private matter rather than a distinct transcendent truth. 

So, what if the opening ceremony was a paean to French values, rooted in the French Enlightenment? And what does that have to do with paganism?  

The first volume of Peter Gay’s monumental two-volume work on the Enlightenment was subtitled: “The Rise of Modern Paganism.” He pointed out how the philosophes of that same Enlightenment - Diderot, Montesquieu, Voltaire, for example - loved Cicero, Lucretius and the rest. Every educated person at the time studied Greek and Latin, yet these men went deeper to revive pagan ideas, culture and sensuality. They wanted an undogmatic religion, with lots of options, just like paganism – and definitely not the dogma of Christianity. Behind its apparent rationalism or tolerance, the Enlightenment was, for Peter Gay, “a political demand for the right to question everything, rather than the assertion that all could be known or mastered by rationality." It was a rejection of a single creed, in favour of multiple ways of life and belief. The era harked back to the classical past, seeing itself as a completion of the Renaissance, finally leaving behind the vestiges of religion that the Renaissance still retained. The Enlightenment was, Gay argued, not so much the birth of a new rational age, but effectively a renewal of an ancient pagan sensual pluralism.

The argument that paganism is returning has a weak and a strong form. The weaker form is that we have returned to a kind of pluralism where there are many objects of worship under an overarching scheme that denies any of them ultimate truth or value.  

Paganism was essentially pluralistic. Pagans believed there were many gods who inhabited the universe and who demanded allegiance. Pagan worship was a kind of bargain, whereby if you paid your dues to the gods by offering sacrifices to them, especially the local ones of your city, they would look after you and ensure that things went well. Yet the language of ‘gods’ is confusing. What pagans meant by ‘gods’ was not what Jews or Christians meant (or mean) by ‘God’. Pagan gods belong to nature. They do not transcend it. Pagan gods were objects within the world, rather than the transcendent source of all things, existing precisely beyond physical reality. As St Augustine pointed out, paganism took the good gifts of God and turned them into gods – objects of devotion that they were never meant to be.  

If paganism was pluralistic, with numerous objects of worship, none of whom could claim absolute allegiance and who ruled over the lives of their devotees, then modern pluralism bears some distinct similarities. A pluralist public space where each of us is entitled to hold our own sense of what is sacred to us, what is of ultimate value, and where no one perspective is favoured as the one, large distinct truth, gets pretty close to a modern kind of paganism.  

Of course there aren’t too many temples to Bacchus, Aphrodite, Tyche or Plutus on street corners in Paris, New York or London. Yet these were the gods of wine, love, chance and wealth. It is hard to deny that the draw of addictive substances, the lure of sex, the hope of a lottery win, or the desire to be rich do not dominate lives in our world.  

There is an old saying that you can tell what someone worships by asking what they would sacrifice most for – or, to put it differently, what they think will make them happy. Worship and sacrifice always went together, whether in the Jerusalem Temple in the Old Testament, in classical paganism, or even in Christianity where St Paul urged the followers of Christ to ‘offer your bodies as a living sacrifice.’ Equally, you can tell what a culture worships by the buildings it puts up. If the classical period put up temples to the gods, the Middle Ages put up cathedrals for the worship of the Christian God, our city skylines testify that we put up countless temples to Mammon.

The stronger form of paganism, identified by Naomi Wolf suggests that darker, older forces are coming back to haunt us. There is an argument that paganism never really went away. It continued to lurk in the corners of European societies as books such as Anton Wessels’ ‘Europe: Was it ever really Christian?’ showed.  

Leslie Newbigin, perhaps the greatest Christian missiologist of recent times, spent most of his life as a missionary in India before returning to the Enlightenment-shaped west in the 1980s. As he did so, he looked back on the idea of a secular society in which there were no commonly acknowledged norms., “We now know”, he argued, “that the only possible product of that ideal is a Pagan society. Human nature abhors a vacuum. The shrine does not remain empty. If the one true image, Jesus Christ, is not there, an idol will take its place.” 

In the UK, we seem about to head down the road towards ‘assisted dying’. The story of Canada should give us pause. Ever since it legalised euthanasia in 2016, stories continue to emerge of people asking for death over such problems as hearing loss or a lack of housing, or feeling they are a burden on their families or the state, and where not just old people are candidates for death – there are now calls for unwanted babies to be killed – we are back with infanticide. In Quebec and in the Netherlands, one in 20 deaths now are self-chosen. In Belgium, such deaths have doubled in the last 10 years.  

If Louise Perry and Naomi Wolf were among those to spot a re-paganisation of culture, it is no accident that both were women. Paganism was bad for women. Tom Holland’s book Dominion was born out of the insight that our world is very different from the classical pagan one. A world where entertainment meant watching wild animals tear the flesh off slaves, where unwanted babies were routinely abandoned, where masters could have sex with whoever they wanted, and could effectively rape young female slaves was a very different world from ours, where such behaviour is criminalised. And for him, the difference was Christianity.  

The problem was, as the early Christians pointed out, that the gods enslave. If you give yourself over entirely to drugs, sex, money or Dionysian pleasure, ultimately, they will rule your life, enslave, and destroy you, as many an addict has discovered. We were never meant to give ourselves to such temporal things – only God, they said – the transcendent source of all goodness - can satisfy and liberate from destructive desire. 

Maybe Eliot was right. It takes a long time to put down religious roots. Islam, Hinduism and Buddhism are only recent imports to Europe and so have shallow roots here. Both Christianity and paganism have gone deep into our soil. Secular pluralism, especially the ‘programmatic kind, always veers backwards towards another version of paganism. And so, European culture only really has two options – the paganism that lasted for centuries before the arrival of Christianity, and the Christianity that replaced it.  

The Olympics offered us two paths. The one offered by the creators of the opening ceremony, the other by the athletes who see a higher goal than a gold medal or earthly fame. The creators of the opening ceremony may not have intended an attack on Christianity. Yet they were happily acclaiming something which Europeans left behind long ago. And we should pause before we celebrate that.
