There was a fascinating piece in the Guardian today by Oliver Burkeman entitled “Why everything you’ve been told about evolution is wrong“. Essentially a review of the ideas in a book by Jerry Fodor and Massimo Piattelli-Palmarini “What Darwin got wrong” and another “The Genius in All of Us: Why Everything You’ve Been Told about Genetics, Talent and IQ is Wrong” by David Shenk (although the immediate riposte by Adam Rutherford said Burkeman had not been tough enough in critiquing the books), the article asked what if – 150 years after the theory of evolution was published – what we think we know about it actually inaccurate?
Burkeman stresses that while what’s being talked about in terms of epigenetics is not new, and is not a filip to creationists, but that it is likely to drive evolutionary biologists mad. And when you read the comments below his article on the Guardian online, how right he was. What vitriol! What scathing nastiness – at one point a G2 subeditor intervened to point out that the article had in fact been read by two scientists with phDs prior to publication – and even this was attacked.
Rutherford attacks him for the Darwin Was Wrong type headline.
But Burkeman’s article basically says that – Darwin knew he was starting the process of understanding the world in a new way, not delivering a complete package that would remain untouched.
Reading the article, it seems to me that the point Burkeman is making is not primarily that Darwin Was Wrong, but that a simplistic understanding of popular science means that the general public’s understanding of genetics affects means that something like learning more about epigenetics means that thinking about its implications feels revolutionary (probably doesn’t if you are a geneticist scientist, but most of us are not). In that way, he is not, as Rutherford suggests, saying that evolutionary biological science cannot already encompass the idea that modifications to the structure of DNA changes its behaviour. He is saying that the public understanding of evolutionary biology is unlikely to be able to cope with such an idea in its simplistic understanding of genetics.
Burkeman’s carefully balanced article is quick to point out that it only the simplistic understanding that is overthrown. He points out that we are taught to believe that genes are permanent and unalterable other than by random mutation.
We’re further taught that natural selection is from a random selection of these potentially randomly mutated genes and cannot be affected by environmental factors. And we’re told that it is simply not the case that certain genes are more likely to be naturally selected to give the next generation a survival advantage, but actually that those genes that are passed on to offspring may or may not confer advantage to an individual offspring, randomly, and that offspring is more likely to have a “better” set of genes for the environment in which the offspring later finds itself and from which their offspring in turn will be produced (the less well adapted for the environment offspring die out).
He uses incredibly derisory language about pro-creationist author Ann Coulter but noted that her comment that treating survival as the only measure of fitness in “survival of the fittest” was effectively a tenet of faith in the American scientific community ”perhaps uniquely among all arguments ever made by Coulter, feels persuasive” (you’d think he’d endoresed her as a champion of evolutionary biology if you only read the comments…)
He admits that it’s possible that Fodor’s thesis (essentially that not every trait a creature possesses is necessarily adaptive, that pop-Darwinists separate traits into those that are selected randomly and those that are selected for their usefulness, but that this can’t be the case because selecting for implies some sort of consciousness in the process) might be nonsense, and even points out that natural selection is
probably not a bankrupt concept, as Fodor claims. But nor should laypeople assume that it’s self-evidently simple and exhaustively true.
And basically, I’m with Burkeman in not being sure that everyone understands that it’s not about “selecting for” i.e. that there is something wrong with the idea that “science proves that polar bears that have white fur because they live in a place where passing on the white fur gene is advantageous”. (NB that’s white meaning colourless, in the sense that the horrible “grey” hairs I have are not really grey but colourless and only appear grey against the lovely brown ones that remain, really weird that the commetns board went wild on that one…)
But even if I underestimate the great British public’s depth of understanding of genetics, it seems that, guess what? It may all be a bit more complicated than that.
How do those that believe we simply pass on our genes and that the circumstances are pitiless, blind and indifferent explain the bred-for-generations scatterbrained mice put in a stimulating environment and producing later generations of offspring with superior memory skills even though the offspring are not kept in the stimulating environment? Surely that shows that how the grandparent mice were nurtured affects the nature of the later generations (or were those grandparent and parent mice demonstrating nurturing behaviour learned from their environment in raising the younger generations? Some how I can’t think that the experiment included giving the chance to the mice to practice their parenting skills and to encourage the baby mice to do braintraining exercises…)
Take the issue of viruses. Viruses seem to play a role in affecting organisms at a genetic level too, not just genes. We may all be a bit more interconnected with other species and other organisms than we perhaps thought.
Rutherford says that knowing this enhances evolutionary theory, rather than contradicting it. It probably does, if you have a deep enough understanding of it.
But this in itself raises a question about whether we are simply the product of our genes which are unconsciously fulfilling their purpose (selfishly, to be replicated) and morality is therefore something that we invent for ourselves and therefore timebound and relative. If viruses affect our genes and their likelihood of being passed on, then restricting the likelihood of viruses that could impact negatively on future generations might be important.
And more widely, if environmental factors affecting the genes that our offspring inherit could include the learning that we undertake as well as our diet, our stress levels and more, then the political and social case for combatting poverty, educating to the very highest standard possible and a whole range of policies need real reconsideration.
Nurture could be affecting nature.
Or is this a case of a little knowledge being dangerously over interpreted?
So it’s the common misuse of the genetic evolutionary story to make pronouncements on moral behaviours (ach, well, men are more prone to sleeping around because you can’t overturn milennia of evolution) and, similarly, the apparent eagerness of some of the high priests of the Darwinian scientific atheistic faith group to treat each of these pronouncements as another nail in the coffin of any theist worldview that Burkeman was criticising.
But Rutherford’s response is worth considering a bit more too.
He seems basically to be saying that by even daring to talk about Fodor’s book as containing interesting ideas that – to the general public with a superficial understanding of genes and evolution rather than deeply knowledgable evolutionary biologists – might seem “mindblowing”, that Burkeman is boosting the case of creationists.
Utter rubbish.
I’ve heard that sort of argument before.
Usually from fundamentalist creationists themselves, to whom the sort of stripped back New Testament matters more than Leviticus, no death penalty, gay life partnerships are a good thing Christianity that Protestants in Europe increasingly tend to believe in is anathema.
Or from believers or clergy that say that that women priests are against women’s nature and that Jesus would not have wanted them.
It’s basically saying that unless discussions on issues that you may be feel are already settled are headlined “Why the people raising about this are credulous fools and don’t understand why we’ve proved that our view is right” then they are implicitly condoning the subject of the discussion. You’re either completely with us, or you’re against us.
Well, ok. Actually a little bit of me has some sympathy.
If you accept that for some people evolutionary biology is in fact a belief system, and that belief systems are both simple on the surface and quite complex, and that they matter to believers because they are true and the basis on which you build your life, then you can begin to understand the somewhat agressive approach that believers can sometimes take when someone misunderstands the more difficult concepts.
As a Christian, it worries me that people profess Christianity, but don’t actually seem to understand it.
If my faith is just about a sky god, and that if you live a good life you’ll go and live with him forever and see everyone that’s died before you again, then a huge number of people are Christian.
But that’s a simplified version that makes no attempt to understand Jesus’s death and ressurection and why it happened, and what it means for us in terms of how we get to spend eternity with God and what being good actually means. People don’t often really know about the age of the gospels, the reality of crucifixtion on a human body, the fulfillment of the Jewish law… and without all that stuff, you either have a weak or a bad God not worth worshipping.
It worries me, because it’s important that people know so that they have the chance to accept Jesus’s gift to us, but it doesn’t anger me as it often does really dogmatic Christians (and yes there’s a fair few out there).
I think it is important to discuss, to debate, exegesis or midrash has long been part of the religious tradition of the Abrahamic faiths (I may have mentioned this before…). It means engaging with believers to sort out what you believe, discussing new ways of looking at it, new ideas and evidence.
But these days it probably also means engaging with non-believers, people of other faiths, some of whom you may find common cause with on some points but accepting that on some you probably won’t. But usually you can try to end up in a place where you can have a discussion and not just hurl insults at each other – call it interfaith dialogue if you must.
Science also has a way of doing this – when a new discovery is made that challenges the old, it is examined (in journals, in the press, in debate, in books) and eventually, if robust enough the old goes, or is adapted to accept the new and so the new becomes the norm. In that old John Maynard Keynes quote that I love you can sum it up as:
When the facts change, I change my mind. What do you do, sir?
But Rutherford concludes:
Unfortunately though, to the knowledgeable, it is a disappointing combination of at best misleading distortion, and at worst plain wrongheadedness. Now we have to clean up the mess.
Believe me, people of other faiths know this too. It’s how most Christians feel about the God Delusion which presented not only a distortion of our beliefs but old discussions as if they were new and knock down arguments.
But then we also know that Christianity is not a religion, it’s a relationship with God.
And evolutionary biological atheism is in the eyes of its believers not a religion either, it’s science.
But it’s funny how the language is so similar, don’t you think?
