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.

Alice Roberts’ new book is the Da Vinci Code without the pretence of fiction

Tomes like Domination are part of the problem of public discourse about Christianity, not the solution

Alice Roberts would like you to read her book, thank you very much.

She recently took to X to bemoan the “epidemic” of people offering thoughts about her latest offering, without actually having read it. The person who prompted Roberts’ exasperation was a senior lecturer in Biblical Studies and the latest in a long of professional scholars of Christianity who had greeted the release of the book with little more than a weary eyeroll. 

The reason so many people felt as though they didn’t need to read it is because it is utterly predictable. Even a cursory glance at any of the marketing that has accompanied the publication of Domination: The Fall of the Roman Empire and the Rise of Christianity really does tell you all you need to know. It really is the book you think it is. 

You already know what this book is going to argue. Just like you already know how this review is going to go. I’m a theology lecturer who works for the Church of England; Roberts is an outspoken atheist and former president of Humanists UK. Of course I’m going to disagree with this book. It’s hardly the sort of plot twist you endure an M. Night Shyamalan film for.

But, for the avoidance of doubt, let me be clear: I don’t dislike Alice Roberts’ book because I’m a Christian and she’s not. I dislike Roberts’ book simply because it’s not very good.  

Roberts seeks to “lift the veil on secrets that have been hidden in plain sight.” (Always be wary of someone who claims to have noticed something no-one else has for the last 2,000 years). These ‘secrets’, she suggests, are that “the main reasons [Christianity spread so successfully] were not to be found in the pages of the Bible, but in a powerful alliance born of complex – and very human – incentives”.  

For Roberts, the central, overriding reason why Christianity flourished was simply economic and political power. In her own words, “the worldly aspects of the Church are undeniable. Wealth and power go hand-in-hand, and the Church had both in abundance.” It’s never clear who actually is thought to be denying this, except a vague group described as “apologist historians (including some who claim not to be Christian, but seem to be suffering from some kind of Stockholm syndrome) and theologians”.  

And this power-grab has been the aim since the earliest moments of the Church’s existence. The Apostle Paul is painted in cartoonishly Machiavellian tones: “As a Pharisee, a member of an established Jewish sect, Saul would have been a small fish in a big pond. The switch to this new breakaway sect [Christianity] would make him a prominent figure in a small but rapidly growing movement”. 

A few pages later – in a section that made me laugh so hard I had to put the book down for a few minutes to collect myself – Roberts offers a genuinely baffling reading of one of Paul’s early letters, to a group of Christians in the city of Corinth. In the letter, Paul speaks about divisions in the Church, with Christians claiming to ‘follow’ different leaders (such as Paul and Apollos). Roberts writes that “there’s a hint that Paul may have viewed Apollos as competitor” and continues: 

“When Paul wrote his first letter to ‘the Corinthians’ … he exhorted them to see themselves as united, whether they were following him, [or] Apollos … Paul, however disgruntled he might have been about the competition represented by other, potentially more eloquent, preachers, had decided it was best to team up. Still, he couldn’t quite resist suggesting his superiority – or at least, his priority – to Apollos: ‘I have planted, Apollos watered.’”. 

See?! SEE?! It’s all about power!! 

Well, that last bit is a quote from Paul’s first letter to the Corinthians, the third chapter and its sixth verse. Now, what Roberts doesn’t tell the reader is that she has left off the rest of the verse, and the verse that follows. “I planted, Apollos watered, but God gave the growth. So neither the one who plants nor the one who waters is anything, but only God who gives the growth.”  

But this is very different indeed to the impression Roberts gives us. Paul is quite clearly not claiming any sense of superiority over Apollos. No, he claims they’re both nothing, and that God alone deserves credit for anything good done by either of them. Not that you would know this from Roberts’ butchering of biblical texts.  

(As a slightly technical aside, the bit Roberts does quote should read ‘I planted,’ not ‘I have planted’. This sounds trivial but in the Greek text, Paul writes in a different tense than the one Roberts translates it as. This made me wonder what translation of the Bible was using or whether it was her own. However, there are no notes in the book. At all. And no mention of Bible translation that I could find. If we’re engaging in character assassinations of folk no longer alive to defend themselves, we might think that attention to the precise wording of their thought might be important. Apparently not). 

And there’s the rub. Roberts leave precisely zero room for earnest belief in God. Not her belief in God, obviously, but that the people whose words she has hacked and placed before us might earnestly think that their actions seek the betterment of those around them because of their belief in God. No. It’s all about power. I’ve highlighted her treatment of Paul in particular (again, because I found it genuinely hilarious), but time would fail me if I tried to recount all the ways that other figures in Church history are treated similarly. 

Roberts’ has complained about Frank Cottrell-Boyce (whom, she notes, is “a Catholic” as though this is in any way relevant to whether he’s right) for describing Domination as ‘cynical’. But how else could we possibly describe this? Yes, it is – of course – completely reasonable to highlight the social, cultural, political, and economic forces at work in and around the development of Christianity (is anyone actually suggesting otherwise?). And yes, of course some people have used Christianity for personal gain (seriously: is anyone actually suggesting otherwise?). 

But Roberts goes far beyond both points. Instead, she is simply stripping back the theological content of Christianity and claiming to have found “secrets that have been hidden in plain sight” having done so. But of course human motivation is all that is left once you strip belief in God out of religion, because what else could there be? Roberts’ prose may be captivating, but her argument is deeply immature and reductive. It’s like a toddler who’s just read Michel Foucault’s work on social power for the first time: an impressive toddler, to be sure, but a toddler nonetheless.  

Roberts does acknowledge that “people are complex, human societies are complex”, but this is little more than lip-service to nuance. None of this complexity is found in the actual argument of her book. It reminds me of someone saying, “no offence, but …” before going on to say something deeply offensive. A fleeting caveat doesn’t redeem a simplistic argument. 

In this respect, it’s quite telling that the front-cover endorsement comes from Stephen Fry who describes it as “a historical thriller of the highest quality.” In one respect, he’s not wrong. It reads like a thriller and – questions of content aside – might easily grip read readers with its compelling prose and rhetorical flourishes. But that’s because this is The Da Vinci Code without the pretence of fiction. A compellingly told conspiracy theory dressed up in just enough spliced-together reality to feign plausibility.  

Public discourse about religion and faith is too often conducted with a sneering cynicism that seeks to ride roughshod over the sincerely held beliefs of actual people who would actually describe themselves as religious. Books like Domination are part of the problem, not the solution.  

Maybe this is why I find Domination bordering on offensive. Not because of its content. (If I got upset every time someone ascribed bad motivations to the Church I’d never leave the house.) No, I find it borderline offensive because of its sheer existence. Whether you like it or not, religion has been and is an irrevocably vital part of who we are and where we’ve come from. Religious belief deserves at the very least to be understood, even if not agreed with. And so, when I finished Domination, I was left wondering: is that is? Is this the highest standard of discourse society can really be offered about religion? Dan Brown in an academic gown? Heaven help us, if so. 

The covers may be similar, and the titles may sound alike, but this is not Tom Holland’s Dominion. Where Holland’s work remains one of the most insightful and thoughtful accessible books about the development of Christianity and modern society, Roberts’ cynicism (for that is what it is) is both tiresome and tiring. (Moreover, that Holland’s book is not even mentioned once speaks volumes about Roberts’ work. That Roberts insists she has read it only makes that absence more baffling). 

The Church deserves more rigorous champions of atheism to scrutinise its belief; society needs a better class of conversation about religion and its role in our history. I fear Alice Roberts is not the former; Domination is certainly not the latter.
