Unweaving the Rainbow by Richard Dawkins (1998)

Here is another analogy… (p.12)

Although this book is over 20 years old, the issues it addresses (the anti-scientific tendency of much traditional literature and the inappropriate use of poetic writing in bogus pseudo-science – versus the hard scientific fact and clear scientific thinking Dawkins promotes) are still very current, and since Dawkins is still writing books attacking non-scientific ways of looking at the world (such as his most recent tome, Outgrowing God, published just last year) I think it’s still worth reviewing this one as an analysis of his overall style and approach.

The aim

The full title is Unweaving the Rainbow: Science, Delusion and the Appetite for Wonder and the book’s purpose is simple: For thousands of years humans have written poetry or concocted religious myths and symbols to explain the puzzling world around them. But (Dawkins says) the scientific worldview as we now have it explains more or less everything about the world around us from bacteria to supernovas and, if properly understood, is far more beautiful and inspiring than the poetry, myths and legends it supersedes.

My advice

However, in my opinion, if you want to be inspired, watch a David Attenborough documentary about the natural world or a Brian Cox one about the stars, because this book is a hilariously silly, shallow, ragbag of random quotes, fragments of science mixed up with countless personal anecdotes, snippets from newspapers or TV and, above all, a relentless stream Richard Dawkins’s pet peeves and trite opinions.

Do not read this book.

Dawkins shares his opinion of modern journalists (lamentably anti-science)

Dawkins opens the book with a sustained attack on a shopping list of contemporary authors who have written disparagingly about science, including Bernard Levin (who once wrote an article specifically about Dawkins God, Me and Mr Dawkins 11 October 1996 – hence the enmity), Simon Jenkins, A.A. Gill, Fay Weldon (author of a ‘hymn of hate’ against science in the Daily Telegraph) and so on and so on.

Dawkins quotes articles in the newspapers, or letters he has received, or questions he gets asked at the end of his lectures, or anecdotes about students of his, to demonstrate that anti-scientific prejudice and ignorance is everywhere – There are creationists under the bed and anti-evolutionists hiding in the closet. It isn’t safe to turn on the TV or open a newspaper without someone spouting unscientific rubbish or promoting astrology or showing the deepest scientific illiteracy. Fools! Knaves! Dawkins has no patience with error.

This is dramatically, profoundly, hugely wrong. (p.90)

Dawkins shares his opinion of British poets (lamentably anti-science)

And then – oh dear, oh dear – Dawkins takes it upon himself to be the judge of a raft of classic poets including Keats, Coleridge or Wordsworth, Blake or Yeats or Lawrence.

Dawkins has located quotes from all of these luminaries lamenting the ‘death of romance’ and the role science has played in ‘dis-enchanting the world’ so, as usual, Richard loses no time in telling us that they were all dead wrong in thinking science dis-enchants the world: if only they’d understood modern science, they’d have written poetry ten times as good!!

Dawkins then goes on to prove that he has absolutely no feel for poetic writing or for the luminous quality of poetry:

  1. by the way he quotes schoolboy tags and the most obvious ‘greatest hits’ moments from the most obvious Great Poets
  2. by the way he treats poems as rhythmic verse i.e you can do a prose summary, and then evaluate them on whether or not they show the ‘correct’ attitude to the scientific worldview
  3. and by the way he has rummaged through the diaries and letters and table talk of the Great Poets to find quotes of them stating anti-scientific or anti-rationalist opinions

Which he considers case closed. He cannot entertain the idea that poetry might not be written to put forward clearly defined and logical points of view, but might be an alternative way of perceiving and expressing the world and what it is to be human…

He refers to D.H. Lawrence who (allegedly) refused to believe that moonlight is reflected sunlight (that sounds too pat and too stupid to be true), but even if it were, you kind of know what Lawrence is talking about. We have evolved over tens of millions of years to find night-time eerie and the changing shape and movement of the moon uncanny. Is it possible that part of a poet’s role is to respect ancient beliefs, to excavate and re-express deep ancestral feelings, no matter how irrational?

Not in Dawkins’s view. No! They were all wrong wrong wrong about science and deserve to be sent to the back of the class. He speculates that:

Keats, like Yeats, might have been an even better poet if he had gone to science from some of his inspiration. (p.27)

If only the Great Poets were more like, well, like Richard Dawkins!

Dawkins’s bêtes noirs and pet peeves

He fills the book with his own Daily Mail prejudices and bêtes noirs.

Post-modernism is rubbish Once again we get his shallow critique of ‘post-modernism’ and ‘cultural relativism’ – ‘the meaningless wordplays of modish francophone savants‘ – which he dismisses in a sentence as existing merely ‘to impress the gullible’ (p.41).

Now maybe a lot of French post-war philosophy is pretentious twaddle, but, for example, Derrida’s attempt to rethink the entire tradition of writing as a way of encoding authority which constantly undermines itself because of the looseness and deeply unfinishable nature of writing, or Foucault’s histories of how power is wielded by supposedly ‘objective’ academic disciplines and public institutions, or Roland Barthes’ explorations of how texts have lives of their own, determined by structures or levels of activity which have hitherto been overlooked – these are all fascinating intellectual endeavours, certainly more worth spending time reading about than the Daily Mail philistinism of Dr D.

It’s a telling irony that soon after a passage attacking writers and journalists (Bernard Levin, Simon Jenkins et al) for their shallow, ignorant dismissal of science as being a worldview which they don’t like — Dawkins himself carries out just such a shallow, ignorant dismissal of post-modern philosophy, for being a worldview which he doesn’t like.

Could it be that there are multiple worldviews, countless worldviews, and that we get along best by enjoying their diversity? No! Wrong wrong wrong!

Children’s book awards are vulgar Dawkins gives an account of attending an awards ceremony for children’s science books where the audience was encouraged to make insect noises, which he found insufferably ‘vulgar’.

Computer games are vulgar In much the same way, in The Blind Watchmaker, he dismissed ‘vulgar’ arcade computer games (not as dignified and worthy as the computer game he had devised, of course).

The ‘Top 20’ shows how vulgar people are This kind of lofty condemnation of ‘popular’ interests and tastes comes, of course, from a long line of lofty and contemptuous Oxford intellectuals, and sits alongside his fastidious disapproval of the so-called ‘Top 40’ and how easy it is to promote ‘worthless pop singles, an attitude of fastidious elitism which made me laugh at the end of The Blind Watchmaker. Later on he finds the space, for obscure personal reasons, to go out of his way to tell us that the activity of bodybuilding is an ‘odd minority culture’. Possibly. But not as odd as writing a book supposedly about science and going out of your way to include a paragraph disapproving of body building.

The X-Files is anti-scientific Dawkins takes the time to explain why he dislikes the popularity of the TV show The X-Files – namely, because of the way it foregrounds the spooky, irrational explanations for the weird occurrences it depicts (p.28) – which is so frightfully anti-science.

Douglas Adams is masterly By contrast, he wants us to know that he approves of the ‘masterly’ science comedies of Douglas Adams (p.29).

Science fiction is serious literature! Science fiction by the likes of Arthur C. Clarke, Isaac Asimov et al:

seems to me to be an important literary form in its own right, snobbishly underrated by some scholars of literature (p.27)

Oh yes, if Dawkins ran literature departments, things would be different! Out with Derrida and Barthes, in with Douglas Adams and Isaac Asimov!

Dr Dolittle is not racist Dawkins finds time to share his opinion that Hugh Lofting’s Dr Dolittle books do have a little racism in them, but then that was the universal worldview of the 1920s, so it is silly for ‘pompously correct librarians’ to ban them. And, anyway, Dolittle’s love of animals is superior to the speciesism which even the most politically correct of our own time are still prey to (p.53).

Ruskin didn’t understand science I was actively upset when Dawkins quotes a passage of Ruskin about how people prefer myths and stories to the cold empirical facts – and then goes on to ridicule Ruskin’s attitude not by countering his views but by retelling the hoary old anecdote about the great critic and social reformer’s disastrous wedding night.

It stood out to me as a moment of gross insensitivity and schoolboy bullying. Ruskin was a genius, who struggled to transform the way the philistine British thought about art and design and handed his cause on to the young William Morris. To drag up this hackneyed anecdote is in the worst possible vein of Daily Mail ad hominem philistinism.


a) Dawkins is a modern reincarnation of just the kind of literal-minded, unbending, unsympathetic and impenetrably dense philistine who forced so many of the Great Poets – Shelley and Byron and Browning, Lawrence and Auden – to flee claustrophobic, puritanical, judgemental England for hotter, more laid-back climes.

b) There seems to be no subject too trivial or too minor for Dawkins not to be able to use it as the pretext to share with the reader his trite and obvious opinions and prejudices, or to prompt another anecdote from his endless store of ‘fascinating’ encounters.

Imagine if David Attenborough interrupted his voiceover about humming birds or polar bears to share an anecdote about a distinguished professor he had a squabble with over dinner at his Oxford college, or took a minute to explain to his viewers why Star Trek is better than Dr Who, or why Douglas Adams’ novels are criminally under-rated.

You’d think he’d gone mad. But that’s what most of this book is like.


Although Dawkins goes out of his way to sound reasonable he can’t help quite frequently sounding like a snob, fastidiously distancing himself from the ghastly taste of the mob. Richard – alongside the Daily Mail – laments how standards have slipped and once-mighty institutions have pandered to popular taste. O Tempora! O mores!

In his chapter rubbishing horoscopes and astrology, Dawkins quotes surveys in which most people say they read horoscopes just for entertainment:

Their taste in what constitutes entertaining fiction is evidently different from mine!

Indeed. Dawkins has told us several times that he cycles through the streets of leafy Oxford. I wonder if he’s ever thought about people like me who have to fight their way onto over-crowded tube trains, or flop exhausted at the end of the day onto a muggy bus, brain dead and pick up a copy of the Metro or Standard to leaf through, treating the horoscopes as much the same as all the other brainless twaddle in it which helps pass the time if you are very, very tired. Different strokes for different folks. Live and let live, maybe…

I chortled when he referred to the Radio Times as ‘that once-respected organ of the BBC’ (p.124). Could anyone sound more pompous?

After taking part in a BBC programme promoting a faith healer who claimed to be the reincarnation of a 2,000-year-old dead doctor, Dawkins clashed with the commissioning editor of this programme. He was horrified that the BBC should:

lend the weight of its long built-up reputation by appearing to accept the fantasy at face value (pp.125-6)

It’s so often the BBC which draws the ire of the Mrs Angry’s from Tunbridge Wells… and so it is for Dawkins. I smiled when he described David Frost as:

a veteran British television personality whom some government saw fit to knight… (p.126)

‘Whom’. I know it’s technically correct but I don’t like using ‘whom’ precisely because Dawkins is typical of the kind of people who still use it, the kind of people who perpetually think the BBC is going to the dogs.

The long chapter demolishing astrologers and fake magicians is an orgy of supercilious superiority to the immoral tricksters who make money be exploiting a gullible public, aided and abetted by intelligent people in places like the BBC who really should know better!

Dawkins’s personal stories and gossip

I’ll begin with a personal anecdote. (p.138)

The book is jam packed with chatty stories and anecdotes from people he’s met, and letters he’s received, and newspapers articles he’s read, and debates he’s taken part in, and lectures he’s given, and children he’s chatted to, and anecdotes about his wife, and his mother-in-law, and his parents, and uncle and aunt.

  • I am told on good authority that defence lawyers in the United States sometimes object to jury candidates on the grounds that they have had a scientific education (p.83)
  • A colleague tells me of a time when he was up for selection on a jury… (p.84)
  • I had a schoolfriend who claimed that he could recognise any member of the 80-strong residence in which we lived purely by listening to their footsteps. (p.88)
  • I had another friend from Switzerland who claimed that when she walked into a room she could tell, by smell, which members of her circle of acquaintances had just left the room. (p.88)
  • I once received a lawyer’s bill, the last item of which was ‘Time spent making out this bill’ (p.106)
  • My wife Lalla Ward recalls an occasion when an American starlet approached the director of the film they were both working on with a ‘Gee, Mr Preminger, what sign are you?’ and received the immortal rebuff, in a thick Austrian accent, ‘I am a Do Not Disturrrb sign.’ (p.118)
  • I once met a woman who was employed full time to invent these stories [Elvis sighted on Mars-type stories] for an American publication… (p.124)
  • I recall an entertaining dinner with a philosopher who told me the following story: One day in church he noticed that a priest, in a kneeling position, was hovering nine inches above the church floor. (p.133)
  • I remember once trying to amuse a six-year-old child at Christmas time by reckoning with her how long it would take Father Christmas to go down all the chimneys in the world. (p.141)
  • I used a similar illustration in one of my Royal Institution Christmas lectures in 1991. (p.145)
  • My wife once bought for her mother a beautiful antique watch with a pink face. (p.154)
  • During this particular minute, my thoughts have strayed to a schoolfellow called Haviland (I don’t remember his Christian name, not what he looked like) whom I haven’t seen or thought of for 45 years. (p.159)
  • Daniel Dennett has told me of a conversation with a philosopher colleague who had read Wonderful Life as arguing that the Cambrian phyla did not have a common ancestor – that they had sprung up as independent origins of life! (p.207)

He spends a page and a half describing the time his parents persuaded little Richard and his sister to put on blindfolds and led them out to the garden where they sat them in a wooden frame which they persuaded the children was an airplane, trundled it along the ‘runway’ and then lifted it into the air and zoomed it around the garden, sometimes brushing against low-hanging branches of trees.

This anecdote is the basis of a couple of pages of complete speculation about why credulity, the ability to believe anything they’re told, might be an evolutionary advantage in human children – but how adults should grow out of it and apply serious scientific standards of scepticism and an informed understanding of statistics to every aspect of their lives.

But why? Why can’t people believe what they want to? In reality they already do, and always have, and always will. Charming, page-long anecdotes about Richard’s upper-middle-class childhood aren’t going to change anyone’s minds, they just warm the hearts of the upper-middle-class book reviewers who, as a result, shower his books with praise (enthusiastic blurbs on the back of this book come from A.S. Byatt [private school and Oxford] and Matt Ridley [the fifth Viscount Ridley, Eton and Oxford]).

On and on it goes in an endless burbling stream of jolly gossip which is entertaining because it’s so inconsequential and vain, a self-satisfied family album of preening opinions.

Sometimes there are bits of science…

Why rainbows appear like they do, sound waves, how we can read the chemical composition of different stars, DNA fingerprinting – there are interesting fragments of actual science, reasonably clearly explained, buried amid all the gossip and personal prejudices.

There’s another explanation of the structure of the eye (repeated from River Out of Eden), a page about qasars, and 4 or 5 pages about ‘Skinner boxes, and the behaviouralist B.F. Skinner’s experiments rewarding animals (pigeons and rats) which led him to notice that animals, too, appear to develop superstitious rituals i.e. if they happened to be doing something (pecking a particular part of the box, or huddling on one particular corner) when some food pops through the chute into the box, then they will repeat the same behaviour again and again in the hope that lightning strikes twice. Like humans who carry out lucky tics and rituals.

There’s a lengthy passage (pp.193-209) attacking Stephen Jay Gould. It’s typical of Dawkins in that he says he respects the great American populariser of evolution, but then goes on to systematically demolish every aspect of Gould’s book Wonderful Life. Gould uses the fossil discoveries in the Burgess Shale to assert that the Cambrian period when they were laid down saw a spectacular and unprecedented explosion of evolutionary growth and diversity, hundreds of wacky designs for life forms, many of which flourished and disappeared. Dawkins powerfully disagrees that evolution works in such bursts and spurts, and lines up a barrage of critics and authorities to demolish Gould’s position, concluding with a quote from Peter Medawar claiming it was a shame that Gould had (before his death in 2002) become the pre-eminent popular exponent of evolutionary theory in the United States because his ideas are ‘confused’ and totally unrepresentative of the mainstream of evolutionary thought (‘in fact the evolutionary biologists with whom I have discussed his work tend to see him as a man whose ideas are so confused as to be hardly worth bothering with…’, p.207).

OK so there’s some science in this passage, as Dawkins explains why he disagrees with Gould but, as you can tell, the explication of the facts of what was found in the Burgess Shale take a poor second place to Dawkins’s argufying about it. The point of these fifteen pages or so is not to explain the thing to you, it’s to convince you that Gould was wrong wrong wrong!

The passage I liked best explained how evolution, among other things, has selected for the correct shapes of key proteins – some crucial proteins have multiple shapes and versions: the correct shapes are the ones which allow them to carry out their life-enabling activities, but it explains why things go disastrously wrong if the body, for whatever reason, starts to produce wrong-shaped alternatives: which is what happens in mad cow disease, when an alternative shape of the prion protein occurs and then triggers a cascade of mishapen prions throughout the body, which leads to holes forming in the brain, and madness.

Moments like this are obviously interesting, but they are oases of sense in a book most of whose text is made up of anecdotes, stories, far-fetched analogies, pitifully simplistic opinions about Great Literature, and a wholesale misunderstanding of human nature.


As to Dawkins’s central point that all kinds of people think unscientifically, don’t understand statistics or probabilities or how DNA fingerprinting works or how the rainbow is made, and instead believe gibberish about horoscopes and astrology and magic tricks… well, so what?

People have always been fools, always will be, as John Gray points out (see my review of his most recent book, The Soul of the Marionette). On the whole, people don’t burn witches or lynch strangers or march gaily off to war like they used to, so that’s progress of a sort.

But expecting everyone to suddenly abandon junk TV, sensationalist tabloid journalism, horoscopes and the countless promises of overnight diets and anti-ageing creams, and suddenly, miraculously, become hyper-intelligent, private-school educated, Oxford academic experts in DNA and astronomy is… well… a fatuous fantasy.

Dawkins and Junior

When my son (22 and studying Biology at university) discovered that I was reading Dawkins’s books, he was genuinely outraged. He crossly told me that all Dawkins’s contributions to biology have been discredited, and that his only achievement has been to create in many people’s minds a vision of science and scientists as narrow-minded, intolerant, anti-religious and bigoted – a view which my son has personally found himself having to extricate himself from in student conversations, and which has been extremely socially unhelpful.


One last Dawkins anecdote to finish with:

In a previous book I gave away the number of the combination lock on my bicycle. I felt safe in doing so because obviously my books would never be read by the kind of person who would steal a bicycle. Unfortunately somebody did steal it, and now I have a new lock with a new number. (p.147)

This vignette perfectly captures Dawkins’s spirit of winning naivety and complete ignorance of human nature. Maybe you can see why, in my review of The Blind Watchmaker, I dubbed Dawkins the Mr Bean of Biology.


Unweaving the Rainbow by Richard Dawkins was published by Penguin in 1998. All references are to the 1999 Penguin paperback edition.

Life At The Speed of Light: From the Double Helix to the Dawn of Digital Life by J. Craig Venter (2013)

The future of biological research will be based to a great extent on the combination of computer science and synthetic biology. (p.204)

Who is Craig Venter?

The quickest way of getting the measure of this hugely clever, ambitious and visionary man is to quote his Wikipedia entry:

John Craig Venter (born October 14, 1946) is an American biotechnologist, biochemist, geneticist, and businessman. He is known for leading the first draft sequence of the human genome and assembled the first team to transfect a cell with a synthetic chromosome. Venter founded Celera Genomics, The Institute for Genomic Research (TIGR) and the J. Craig Venter Institute (JCVI), where he currently serves as CEO. He was the co-founder of Human Longevity Inc. and Synthetic Genomics. He was listed on Time magazine’s 2007 and 2008 Time 100 list of the most influential people in the world. In 2010, the British magazine New Statesman listed Craig Venter at 14th in the list of ‘The World’s 50 Most Influential Figures 2010’. He is a member of the USA Science and Engineering Festival’s Advisory Board.

So he’s a heavy hitter, invited to Bill Clinton’s White House to announce his team’s successful sequencing of the first human genome on 2000, founder of a thriving biochem business, a number of charities, pioneer of genomics (‘the branch of molecular biology concerned with the structure, function, evolution, and mapping of genomes’) and mapper of an ambitious future for the new science of synthetic biology.

In Schrödinger’s footsteps

Life At The Speed of Light was published in 2013. It originated as a set of lectures. As he explains in the introduction, in 1943, the Austrian physicist Erwin Schrödinger had fled the Nazi-controlled Continent and settled in Ireland. Schrödinger was invited by the Taoiseach of the time to give some public lectures and chose the topic of life – the biology and physics of life. Schrödinger’s lectures were then published in the little book What Is Life? (1944) which inspired generations of young people to take up science (in his memoir The Double Helix James Watson describes how the book inspired him; Addy Pross named his book about the origins of life, What Is Life?, as a direct tribute to Schrödinger’s text).

Well, 49 years later Venter was invited by the Taoiseach of the day to deliver a new set of lectures, addressing the same question as Schrödinger, but in doing so, making clear the enormous strides in physics, chemistry, biology, biochemistry and genetics which had been made in that half-century.

Twelve chapters

The twelve chapters are titled:

  1. Dublin, 1943-2012
  2. Chemical synthesis as proof
  3. Dawn of the digital age of biology
  4. Digitizing life
  5. Synthetic Phi X 174
  6. First synthetic genome
  7. Converting one species into another
  8. Synthesis of the M. mycoides genome
  9. Inside a synthetic cell
  10. Life by design
  11. Biological transportation
  12. Life at the speed of light

Each chapter contains a formidable amount of state-of-the-art biochemical knowledge. The first few chapters recap relevant forebears who helped figure out that DNA was the vehicle of heredity, beginning right back at the start with Aristotle, who made the primal division of living things into animal, vegetable or mineral, and then going on to namecheck other pioneers such as Robert Hook and, of course, Charles Darwin.


But the real thrust of the book is to get up to date with contemporary achievements in sequencing genomes and creating transgenic entities i.e. organisms which have had the DNA of completely separate organisms stitched into them.

In order to do this Venter, of course, has to describe the molecular mechanisms of life in great detail. Successive chapters go way beyond the simplistic understanding of DNA described in James Watson’s book about the double helix, and open up for the reader the fantastical fairyland of how DNA actually works.

He explains the central role of the ribosomes, which are the factories where protein synthesis takes place (typical human cells contain about a thousand ribosomes), and the role of messenger RNA in cutting off snippets of DNA and taking them to the ribosome.

It is to the ribosome that transfer RNA (tRNA) brings along amino acids, which are then intricately assembled according to the sequence of bases found on the original DNA. Combinations of the twenty amino acids are assembled into the proteins which all life forms are made of – from the proteins which make up the cell membrane, to collagen which accounts for a quarter of all the proteins found in vertebrate animals, or elastin, the basis of lung and artery walls, and so on and so on.

I found all this mind-boggling, but the most striking single thing I learned is how fast it happens, and that it needs to happen so unrelentingly.


Venter explains that protein synthesis requires only seconds to make chains of a hundred amino acids or more. Nowadays we understand the mechanism whereby the ribosome is able to ratchet RNAs laden with amino acids along its production lines at a rate of fifteen per second! Proteins need to ‘fold’ up into the correct shape – there are literally millions of possible shapes they can assume but they only function if folded correctly. This happens as soon as they’ve been manufactured inside the ribosome and takes place in a few thousandths of a second. The protein villin takes six millionths of a second to fold correctly!

I had no idea that some of the proteins required for life to function (i.e. for cells to maintain themselves) exist for as little as forty-five minutes before they decay and cease to work. Their components are then disassembled and returned to the hectic soup which is contained inside each cell membrane, before being picked up by passing tRNA and taken along to the ribosome to be packaged up into another useful protein.


It is the absolutely relentless pressure to produce thousands of different proteins, on a continuous basis, never faltering, never resting, which makes the mechanisms of life so needy of resources, and explains why animals need to be constantly taking in nutrition from the environment, relentlessly eating, drinking, breaking food down into its elementary constituents and excreting waste products.

After a while the book began to make me feel scared by the awesome knowledge of what is required to keep ‘me’ going all day long. Just the sheer effort, the vast amount of biochemical activity going on in every one of the forty or so trillion cells which make up my body, gave me a sense of vertigo.

Every day, five hundred billion blood cells die in an individual human. It is also estimated that half our cells die during normal organ development. We all shed about five hundred million skin cells every day. As a result you shed your entire outer layer of skin every two to four weeks. (p.57 – my italics)

Life is a process of dynamic renewal.

In an hour or even less a bacterial cell has to remake all of its proteins or perish. (p.62)

Venter’s achievements

Having processed through the distinguished forebears and pioneers of biochemistry, Venter comes increasingly to the work which he’s been responsible for. First of all he describes the process behind the sequencing of the first human genome – explaining how he and his team devised a vastly faster method of sequencing than their rivals (and the controversy this aroused).

Then he goes on to tell how he led teams which looked into splicing one organism’s DNA into another. And then he explains the challenge of going to the next phase, and creating life forms from the DNA up.

In fact the core of the book is a series of chapters which describe in minute and, some might say, quite tedious detail, the precise strategies and methodologies Venter and his teams took in the decade or so from 2000 to 2010 to, as he summarises it:

  • synthesise DNA at a scale twenty times faster than previously possible
  • develop a methodology to transplant a genome from one species to another
  • solve the DNA-modification problems of restriction enzymes destroying transplanted DNA

Successive chapters take you right into actual meetings where he and colleagues discussed how to tackle the whole series of technical problems they faced, and explains in exquisite detail precisely the techniques they developed at each step of the way. He even includes work emails describing key findings or turning points, and the texts he exchanged with colleagues at key moments (pp.171-2).

After reading about a hundred of pages of this my mind began to glaze over and I skipped paragraphs and then pages which describe such minutiae as how he decided which members of the Institute to put in charge of which aspects of the project and why — because I was impatient to get to the actual outcomes. And these outcomes have been dramatic:

In May 2010, a team of scientists led by Venter became the first to successfully create what was described as ‘synthetic life’. This was done by synthesizing a very long DNA molecule containing an entire bacterium genome, and introducing this into another cell … The single-celled organism contains four ‘watermarks’ written into its DNA to identify it as synthetic and to help trace its descendants. The watermarks include:

    • a code table for entire alphabet, with punctuations
    • the names of 46 contributing scientists
    • three quotations
    • the secret email address for the cell.

Venter gives a detailed description of the technical challenges, and the innovations his team devised to overcome them, in the quest to create the first ever synthesised life form in chapter 8, ‘Synthesis of the M. mycoides genome’.

More recently, after the period covered by this book (although the book describes this as one of his goals):

On March 25, 2016 Venter reported the creation of Syn 3.0, a synthetic genome having the fewest genes of any freely living organism (473 genes). Their aim was to strip away all nonessential genes, leaving only the minimal set necessary to support life. This stripped-down, fast reproducing cell is expected to be a valuable tool for researchers in the field. (Wikipedia)

The international nature of modern science

One notable aspect of the text is the amount of effort he puts into crediting other people’s work, and in particular the way these consists of teams.

When Watson wrote his book he could talk about individual contributors like Linus Pauling, Maurice Wilkins, Oswald Avery, Erwin Chergaff or Rosalind Franklin. One of the many things that has changed since Watson’s day is the way science is now done by large teams, and often collaborations not only between labs, but between labs around the world.

Thus at every step of his explanations Venter is very careful indeed to give credit to each new insight and discovery which fed into his own team’s work, and to namecheck all the relevant scientists involved. It was to be expected that each page would be studded with the names of biochemical processes and substances, but just as significant, just as indicative of the science of our times, is the way each page is also freighted with lists of names – and also, just how ethnically mixed the names are – Chinese, Indian, French, German, Spanish – names from all around the world.

Without anyone having to explain it out loud, just page after page of the names alone convey what a cosmopolitan and international concern modern science is.

A simplified timeline

Although Venter spends some time recapping the steady progress of biology and chemistry into the 20th century and up to Watson and Crick’s discovery, his book really makes clear that the elucidation of DNA was only the beginning of an explosion of research into genetics, such that genetics – and the handling of genetic information – are now at the centre of biology.

1944 Oswald Avery discovered that DNA, not protein, was the carrier of genetic information
1949 Fred Sanger determined the sequence of amino acids in the hormone insulin

1950 Erwin Chargaff made the discoveries about the four components of DNA which became known as Chargaff’s Rules, i.e. the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units, strongly suggesting they came in pairs
1952 the Miller-Urey experiments show that organic molecules could be created out of a ‘primal soup’ and electricity
1953 Watson and Crick publish structure of DNA
1953 Barbara McClintock publishes evidence of transposable elements in DNA, aka transposons or jumping genes
1955 Heinz Fraenkel-Conrat and biophysicist Robley Williams showed that a functional virus could be created out of purified RNA and a protein coat.
1956 Arthur Kornberg isolated the first DNA polymerizing enzyme, now known as DNA polymerase I

1961 Marshall Nirenberg and Heinrich J. Matthaei discover that DNA is used in sets of three called ‘codons’

Life at the speed of light

Anyway, this is a book with a thesis and a purpose. Or maybe two purposes, two sides of the same coin. One is to eradicate all irrational, magical beliefs in ‘vitalism’, to insist that life is nothing but chemistry. The other is for Venter to proclaim his bold visions of the future.

1. Anti-vitalism

The opening chapter had included a brief recap of the literature and fantasy of creating new life, Frankenstein etc. This turns out to be because Venter is a fierce critic of all traditions and moralists who believe in a unique life force. He is at pains to define and then refute the theory of vitalism – ‘the theory that the origin and phenomena of life are dependent on a force or principle distinct from purely chemical or physical forces.’ Venter very powerfully believes the opposite: that ‘life’ consists of information about chemistry, and nothing more.

This, I think, is a buried motive for describing the experiments carried out at his own institute in such mind-numbing detail. It is to drill home the reality that life is nothing more than chemistry and information. If you insert the genome of one species into the cells of another they become the new species. They obey the genomic or chemical instructions. All life does. There is no mystery, no vital spark, no élan vital etc etc.

A digression on the origins of life

This is reinforced in chapter 9 where Venter gives a summary of the work of Jack W. Szostak into the origin of life.

Briefly, Szostak starts with the fact that lipid or fat molecules are spontaneously produced in nature. He shows that these tend to link up together to form ‘vesicles’ which also, quite naturally, form together into water-containing membranes. If RNA – which has been shown to also assemble spontaneously – gets into these primitive ‘cells’, then they start working, quite automatically, to attract other RNA molecules into the cell. As a result the cell will swell and, with a little shaking from wind or tide, replicate. Voilà! You have replicating cells containing RNA.

Venter then describes work that has been done into the origin of multicellularity i.e. cells clumping together to co-operate, which appears to have happened numerous times in the history of life, to give rise to a variety of multicellular lineages.

Venter goes on to describe one other major event in the history of life – symbiogenesis – ‘The theory holds that mitochondria, plastids such as chloroplasts, and possibly other organelles of eukaryotic cells represent formerly free-living prokaryotes taken one inside the other in endosymbiosis.’

In other words, at a number of seismic moments in the history of life, early eukaryotic cells engulfed microbial species that were living in symbiosis with them. Or to put it another way, early cells incorporated useful microbes which existed in their proximity, entirely into themselves.

The two big examples are:

  • some two billion years ago, when a eukaryotic cell incorporated into itself a photosynthetic bacterial algae cell which ultimately became the ‘chloroplast‘ – the site where photosynthesis takes place – in all successive plant species
  • and the fact that the ‘power packs’ of human cells, known as mitochondria, carry their own genetic code and have their own way of reproducing, indicating that they were taken over whole, not melded or merged but swallowed (it is now believed that human mitochondria derived from a specific bacterium, Rickettsia, which survives down to this day)

This information is fascinating in itself, but it is clearly included to join up with the detailed description of the work in his own institute in order to make the overwhelming case that life is just information and that DNA is the bearer of that information.

It obviously really irritates Venter that, despite the overwhelming weight of the evidence, people at large – journalists, philosophers, armchair moralists and religious believers – refuse to accept it, refuse to face the facts, and still believe there is something special about life, that humans, in particular, have a soul or spirit or other voodoo codswallop.

2. Creating life

The corollary of Venter’s insistence that there being nothing magical about ‘life’, is the confident way he interprets all the evidence he has so painstakingly described, and all the dazzling achievements he has been involved in, as having brought humanity to the brink of a New Age of Life, a New Epoch in the Evolution of Life on Earth.

We have now entered what I call ‘the digital age of biology’, in which once distinct domains of computer codes and those that program life are beginning to merge, where new synergies are emerging that will drive evolution in radical directions. (p.2)

The fusion of the digital world of the machine and that of biology would open up the remarkable possibilities for creating novel species and guiding future evolution. (p.109)

In the final chapters of this book Venter waxes very lyrical about the fantastic opportunities opening up for designing DNA on computers, modeling the behaviour of this artificial DNA, fine-tuning the design, and then building new synthetic organisms in the real world.

The practical applications know no limits, and on page 221 he lists some:

  • man-made organisms which could absorb the global warming CO2 in the air, or eat oil pollution, turning it into harmless chemicals
  • computer designing cures for diseases
  • designing crops that are resistant to drought, that can tolerate disease or thrive in barren environments, provide rich new sources of protein and other nutrients, can be harnessed for water purification in arid regions
  • designing animals that become sources for pharmaceuticals or spare body parts
  • customising human stem cells to regenerate damaged organs and bodies

Biological transformations

The final two chapters move beyond even these sci-fi goals to lay out some quite mind-boggling visions of the future. Venter builds on his institute’s achievements to date, and speculates about the kinds of technologies we can look forward to or which are emerging even as he writes.

The one that stuck in my mind is the scenario that, when the next variety of human influenza breaks out, doctors will only have to get a sample of the virus to a lab like Venter’s and a) they will now be able to work out its DNA sequence more or less the same day b) they will then be able to design a vaccine in a computer c) they will be able to create the DNA they have designed in the lab much faster than ever possible before but d) they will be able to email the design for this vaccine DNA anywhere in the world, at the speed of a telephone wire, at the speed of light.

That is what the title of the book means. New designs for synthesised life forms can now be developed in computers (which are working faster and faster) and then emailed wherever they’re required i.e. to the centre of the outbreak of a new disease, where labs will be able to use the techniques pioneered by Venter’s teams to culture and mass produce vaccines at record speeds.

Scientific myopia

I hate to rain on his parade, but I might as well lay out as clearly as I can the reasons why I am not as excited about the future as Venter. Why I am more a J.G. Ballard and John Gray man than a Venter man.

1. Most people don’t know or care Venter takes the position of many of the scientists I’ve been reading – from the mathematicians Alex Bellos and Ian Stewart through to the astrophysicists Stephen Hawking and Paul Davies and Paul Barrow, to the origin-of-life men Cairns-Smith and Addy Pross – that new discoveries in their fields are earth-shatteringly important and will make ordinary people stop in their tracks, and look at their neighbour on the bus or train and exclaim, ‘NOW I understand it! NOW I know the meaning of life! NOW I realise what it’s all about.’

A moment’s reflection tells you that this simply won’t happen. Einstein’s relativity, Schrödinger and Bohr’s quantum mechanics, the structure of DNA, cloning, the discovery of black holes – what is striking is how little impact most of these ‘seismic’ discoveries have had on most people’s lives or thinking.

Ask your friends and family which of the epic scientific discoveries of the 20th century I’ve listed above has made the most impact on their lives. Or they’ve even heard of. Or could explain.

2. Most people are not intellectuals This error (the notion that ordinary people are excited about scientific ‘breakthroughs’) is based on a deeper false premise, one of the great category errors common to all these kind of books and magazine articles and documentaries – which is that the authors think that everyone else in society is a university-educated intellectual like themselves, whereas, very obviously, they are not. Trump. Brexit. Most people in western democracies are not university-educated intellectuals.

3. Public debate is often meaningless Worse, university-educated intellectuals have a bad habit of believing that something called ‘education’ and ‘public debate’ will control the threat posed by these new technologies:

Opportunities for public debate and discussion on this topic must be sponsored, and the lay public must engage with the relevant issues. (p.215)

Famous last words. Look at the ‘debate’ surrounding Brexit. Have any of the thousands of articles, documentaries, speeches, books and tweets helped solve the situation? No.

‘Debate’ hardly ever solves anything. Clear-cut and affordable solutions which people can understand and get behind solve things.

4. A lot of people are nasty, some are evil Not only this but Venter, like all the other highly-educated, middle-class, liberal intellectuals I’ve mentioned, thinks that people are fundamentally nice – will welcome their discoveries, will only use them for the good of mankind, and so on.

Megalolz, as my kids would say. No. People are not nice. The Russians and the Chinese are using the internet to target other countries’ vital infrastructures, and sow misinformation. Islamist warriors are continually looking for ways to attack ‘the West’, the more spectacular, the more deaths, the better. In 2010 Israel is alleged to have carried out the first cyberattack on another nation’s infrastructure when it (allegedly) attacked a uranium enrichment facility at Iran’s Natanz underground nuclear site.

In other words, cyberspace is not at all a realm where high-minded intellectuals meet and debate worthy moral issues, and where synthetic biologists devise life-saving new vaccines and beam them to locations of epidemic outbreaks ‘at the speed of light’. Cyberspace is already a war zone.

And it is a warzone in a world which contains some nasty regimes, not just those which are in effect dictatorships (Iran, China) but even many of the so-called democracies.

Trump. Putin. Erdogan. Bolsonaro. Viktor Orban. These are all right-wing demagogues who were voted into power in democratic elections.

It seems to me that both the peoples, and the leaders, who Venter puts his faith in are simply not up to the job of understanding, using wisely or safeguarding, the speed of light technology he is describing.

Venter goes out of his way, throughout the book, to emphasise how socially responsible he and his Institute and his research have been, how they have taken part in, sponsored and contributed to umpteen conferences and seminars, alongside government agencies like the FBI and Department of Homeland Security, into the ‘ethics’ of conducting synthetic biology (i.e. designing and building new organisms) and into its risks (terrorists use it to create lethal biological weapons).

Indeed, most of chapter ten is devoted to the range of risks – basically, terrorist use or some kind of accident – which could lead to the release of harmful, synthesised organisms into the environment – accompanied by a lot of high-minded rhetoric about the need to ‘educate the public’ and ‘engage a lay audience’ and ‘exchange views’, and so on…

I believe that the issue of the responsible use of science is fundamental… (p.215)

Quite. But then the thousands of scientists and technicians who invented the atom bomb were highly educated, highly moral and highly responsible people, too. But it wasn’t them who funded it, deployed it and pushed the red button. Good intentions are not enough.
