Long tails, tall tales
A review of The Ancestor’s Tale: A Pilgrimage to the Dawn of Evolution
by Richard Dawkins
Houghton Mifflin, New York, 2004
reviewed by Lael Weinberger
Richard Dawkins is a wonderful wordsmith. I couldn’t help but chuckle at the
title of this book, The Ancestor’s Tale, with its clever wordplay
(‘tale’ and ‘tail’).1
It only gets better with the subtitle, A Pilgrimage to the Dawn of Evolution.
‘Pilgrimage’ seems curiously religious terminology for the world’s
most famous atheistic scientist.2
But this is not at all surprising—Dawkins revels in his role as a ‘devil’s
chaplain’3 and delights
to speak of the wonders of science in sanctimonious tones, his alternative religion.
The title for this book turned out to summarize the book in more ways than one.
Backwards pilgrimage
The subtitle gives away one key component of the plot: Dawkins isn’t going
to give us the normal story of evolution by starting at the start and ending with
the present (and usually, that means us—humankind). Instead, Dawkins is going
to take us on a pilgrimage backwards in time, starting at the present and tracing
our ancestors back. The journey is punctuated by what he calls ‘rendezvous
points’, junctures in the evolutionary phylogenies which in forward time would
be the occasion for major groups to split off from our common descent and proceed
on their own independent evolutionary saga. But in Dawkins’ backwards time,
these are the points where the major groups rejoin us on a collective trek to meet
our common ancestors—Dawkins terms these ‘concestors’. Taking
a cue from Chaucer’s Canterbury Tales, the creatures we meet at these
rendezvous points always have tales to tell. When Dawkins first introduced this
format in his prologue, I wondered whether he actually intended to give us the tales
in first person. I cannot say that I was disappointed that the answer was no—600
pages of talking animals would have been a bit much.
Dawkins does however allow a few animals to interject comments in the first person
on rare occasion. The final tale closes with a comment from the bacterium Thermus
aquaticus. While a cute touch, the bacterium has quite an attitude—and
highlights one of the recurring lessons in the book:
‘Look at life from our perspective, and you eukaryotes will soon cease giving
yourselves such airs. You bipedal apes, you stump-tailed tree shrews, you desiccated
lobe-fins, you vertebrated worms, you Hoxed-up sponges, you newcomers on the block,
you eukaryotes, you barely distinguishable congregations of a monotonously narrow
parish, you are little more than fancy froth on the surface of bacterial life. …
We were here before you arrived, and we shall be here after you are gone’
(p. 558).
Dawkins has already taken a beating at the hands of a number of fellow evolutionist
scholars for his tendency to use value-laden progressive terminology.
The lesson, of course, is the non-specialness of humans in the grand scheme of life.
This, in fact, is a major reason for the backwards chronology of the book. Dawkins
feared that a forward chronology would give the appearance of ‘aimed evolution’,
with man at the top of a ‘progressive’ evolutionary sequence.4 Dawkins has already taken
a beating at the hands of a number of fellow evolutionist scholars (recently and
notably Michael Ruse5,6) for his tendency to use value-laden progressive
terminology, and bringing in a new emphasis on human non-specialness is a bone to
these critics. Dawkins has not given up on ‘progress’—far from
it, as he makes clear in his final chapter. But he believes equally strongly that
humankind as a species needs to be put into evolutionary perspective, humbled from
some idea of specialness.7
This is what he emphasizes repeatedly in The Ancestor’s Tale.
In one of his favourite examples, Dawkins points to various species of birds and
salamanders, where species A can breed with species B and species B with species
C, but where A cannot interbreed with C (pp. 300–302). Look, Dawkins tells
us, species barriers aren’t as hard and fast as we tend to make them out to
be. (Creationists of course have been saying this for years—the species barrier
does not coincide with the real dividing point of ‘kinds’. Indeed, a
common hybrizidation criterion for ‘kinds’ allows for this transitive
relationship.8) The larger
lesson Dawkins draws is that all of animal life can be laid out like that, if we
only had all of our evolutionary ancestors alive at once. And because of this, we
need to get rid of our ‘discontinuous’ mental tendencies:
‘ … many of our legal and ethical principles depend on the separation
between Homo sapiens and all other species. Of the people who regard abortion
as a sin … many are unthinking meat-eaters, and have no worries about chimpanzees
being imprisoned in zoos and sacrificed in laboratories’ (p. 303).

A recurring theme in The Ancestor’s Tale is the ‘non-specialness’
of humans. If elephants were the scientists, Dawkins writes, they would be fixated
on discovering which life forms ‘have crossed the nasal rubicon and taken
the final leap to full proboscitude.’
It is only the ‘discontinuous mind’ that imagines the clear-cut separation,
and thereby panders to our own vanity and convenience (speciesism, Dawkins calls
it).9
Yet at the end of the book, we find Dawkins clinging to progress. He believes that
there is some type of objective, real progress (he even dares to call it ‘value
laden’) embodied in the evolutionary progression. In an evolutionary ‘arms
race’, for instance, the predators are ‘themselves evolving in a systematic
direction, getting systematically worse from their victims’ point of view’
(p. 601).
But Dawkins doesn’t want to be seen as caving in to some sort of inner need
for humans to be special—this is one aspect of progressive ideology that Dawkins
abhors. Hence the emphasis on ‘non-special’ man. In a memorable passage,
Dawkins writes,
‘A historically minded swift, understandably proud of flight as self-evidently
the premier accomplishment of life, will regard swiftkind … as the acme of
evolutionary progress. … Elephant astronomers might wonder whether …
there exist alien life forms that have crossed the nasal rubicon and taken the final
leap to full proboscitude’ (p. 6).
Dawkins is saying that our human fixation on brains, language, and the like are
just specific cases of our ‘speciesism’. Yet as Michael Behe acerbically
commented, what would the elephants be contemplating this question with—their
noses?
In effect, he is saying that our human fixation on brains, language, and the like
are just specific cases of our ‘speciesism’. Yet as Michael Behe acerbically
commented, what would the elephants be contemplating this question with—their
noses?10 There really
is something unique and quite special about the mind when contrasted with any other
physical feature.11 Dawkins
just can’t—or won’t—see it.
So Dawkins remains in tension between his progressive ideals on the one hand, and
his denial of human specialness. On the one hand, the countless distinctions between
humans and animals12 have
to be brushed over, or better still, buried under as many examples of similarity
as we can find. This tortured approach is necessary for Dawkins, because to have
it any other way—to claim some area of specialness for people—is a vestige
of the biblical creation account, which has man created special: ‘in the image
of God’ (Genesis 1:26–27). On the other hand, Dawkins cannot
bear to abandon the notion of biological progress, with all its religious overtones.
Michael Ruse, no creationist, has brought the religious aspects to light admirably.
Progress is comfortable, hopeful and future-oriented; it fills the need for an evolutionary
eschatology.13 Yet this
might imply something—if people came late in a progressive evolutionary sequence,
might we be special after all (at least in a relative sense)? Such are the conundrums
of a religious evolutionist.
Trapped in metaphor
A prominent attorney and law school dean once commented that his trial successes
were due in part to the proper use of metaphor and analogy. ‘If your analogy
is good, the jury will be stuck with it. You’ve roped them with it, and they
can’t escape.’ Even facts that don’t quite fit get interpreted
in light of the analogy. To some extent I think this applies to Dawkins. The Ancestor’s
Tale is a grand-scale romp through the ranks of all of life, from shrews
to cauliflowers. Dawkins covers an encyclopedic range of zoological subjects. For
him, everything makes sense in light of evolution. He appears genuinely oblivious
to the anomalies in the theory. Very often, he probably is. Evolution is a metaphor
that shapes the way he thinks. Even facts that don’t quite fit get interpreted
in light of it.
Dawkins doesn’t once contemplate whether these exceedingly improbable occurrences
cast any doubt on evolution as a whole.
Convergent evolution is the classic example. When two animals going separate evolutionary
ways independently evolve the same feature, what this really means is that the extraordinarily
improbable14 happened
twice. This really ought to be considered an anomaly for those who accept
evolutionary common descent.15
Dawkins mentions a host of examples. Old World and New World monkeys evolved trichromatic
vision independently of each other (and still more odd, independently of their reptilian
ancestors) (p. 146). Jet propulsion has evolved twice independently (p. 591). ‘True
flapping flight’ (not gliding) has evolved four times (p. 591). The eye evolved
40 to 60 times (p. 588).
In all this, Dawkins doesn’t once contemplate whether these exceedingly improbable
occurrences cast any doubt on evolution as a whole. Dawkins actually uses them as
indicators of what is likely to evolve—suggesting that if the tape of life
were replayed, echolocation would probably evolve again, since four animals independently
evolved it (p. 589). To one who is not already a believer, the audacity is breathtaking.
Echolocation is itself an evolutionary puzzle, and to suggest that it evolved four
times multiplies the problems by as much.16
To proceed from this to say that it would be likely to evolve again if evolution
were repeated is to pile inference upon improbability—only a dedicated believer
could miss the leaps of logic along the way.
Telling the tale

In his discussion of axolotls, tadpoles and frogs, Dawkins tips his hat to the ‘information
challenge’, apparently without realizing it (or at least hoping his readers
do not notice it).
Of course, Dawkins has heard enough critics of Darwinism that he cannot always be
oblivious to the problems. But The Ancestor’s Tale was not the place
for answering critics. Sometimes, this means just ignoring the criticism and probably
hoping that the readers aren’t thinking too much about it. For instance, in
telling the ‘axolotl’s tale’, Dawkins suggests that ‘we
can easily imagine a frog-like adult ancestor evolving into a tadpole-like adult
descendant, because all frogs contain the genes for making a tadpole’ (p.
315). Well, that certainly does help, does it not, having the necessary genes already?
An axolotl is ‘tadpole-like’ and Dawkins says it came from a froglike
ancestor which had part of its development suppressed.17 But, Dawkins tells us frogs came from a jawless
concestor who lived at rendezvous 22—a creature that did not genetically
‘know’ how to be a frog. This screams ‘information challenge’18—and it seems incredible
that Dawkins, knowing that this is the favourite attack point for his creationist
and ID critics,19 would
tip his hat to information as he did in the axolotl’s tale without saying
something to answer them.
Dawkins is very good at using his storytelling skills to put together a (superficially)
seamless Darwinian tale, ironing out rough spots with the stroke of a pen. The conclusion
of the pilgrimage is one long example. Dawkins’ ‘Canterbury’ is
the origin of life. Dawkins tells the whole story of early origin-of-life theorizing
by Darwin,20 Oparin, Haldane,
Miller and Urey, and then arrives at the currently popular ‘RNA first’
theory for life. When he gets to this, he spends four pages explaining enzymes (pp.
568–571) and a couple more on autocatalysis (pp. 571–573), before finally
getting to the heart of the RNA theory: RNA as both replicator and catalyst. Dawkins
sets up the story so that the ‘RNA World’ scenario answers virtually
all of the questions he raised in his long build up about enzymes. A popular-level
audience will presumably be overwhelmed with the explanatory power of the new theory.
So when Dawkins acknowledges at the end of the chapter, ‘There are many other
theories that I have not gone into’ (p. 581), the reader hardly gets a feel
for the intense controversy that still swirls around this area even among the most
sanguine evolutionists.21
A well-told (and long) story is quite effective at covering over complicated scientific
controversies.
What’s in a name
Dawkins’ title did indeed summarize the book well. A ‘tale’ it
is. Dawkins does have a knack for explaining scientific concepts with interesting
analogies and witty turns of phrase. This, and his dogmatic antitheism, is what
made him a candidate for an endowed chair of ‘the public understanding of
science’ at a secular university anyway. Dawkins has not cared much for publishing
research in the scientific journals in recent years,22 preferring a public literary career (as a glance
at his curriculum vitae shows23). In the past several years particularly, Dawkins has tended to wander completely
off scientific topics in favour of religion bashing.24 The Ancestor’s Tale is important
in his professional career as the most significant science-oriented work he has
produced in almost a decade. It is certainly the most massive, and its scope is
impressive. Yet for his most significant science work in quite some time, it remains
very much a popular science work. It is a ‘tale’ on a grand scale.
Yet for his most significant science work in quite some time, it remains very much a popular science work. It is a ‘tale’ on a grand scale.
The Ancestor’s Tale bears the marks of one who has been working on
articles rather than books for quite some time. The ‘tales’ told by
the ‘pilgrims’ are all winningly told, but they are uneven and unpredictable.
They range from one to twelve or more pages. They vary from a simple description
of a feeding habit (pp. 467–469), to an extended discussion of how to build
a phylogeny (pp. 123–136). Sometimes the story is just about the species whose
‘tale’ is being told, and sometimes the eponymous ‘tale’
of the section merely serves as a convenient jumping off point, and the tale continues
with hardly a mention of the species. (‘The Redwood’s Tale’ is
about dating methods, and spends about five times as many pages talking about radioactive
dating methods rather than counting rings in trees.25) Sometimes also, even Dawkins’ wonderful
ability to communicate at the popular level seems too much, making me wonder what
he was thinking about his audience. The analogies are too elaborate; the scene setting
takes too long. And when he throws out certain bits of information, such as ‘All
matter is made of atoms’ (p. 517), I wonder whether he actually expects that
someone who does not know this will be ploughing through a 600-page book
that often uses species’ scientific names.
The book’s subtitle (A Pilgrimage to the Dawn of Evolution) is also
well chosen. As the agent to ‘dethrone’ religion (the ‘root of
all evil’ in Dawkins’ view26), evolution is the hero of the plot for the advance of right thinking. And evolution
is the source, the non-divine creator, of the natural world, a world that inspires
in Dawkins that sense of awe that is effectively a replacement religion. A religious
‘pilgrimage’ is a wonderful metaphor for Dawkins’ view of evolution.
Reading The Ancestor’s Tale is something like reading a wittily written
encyclopaedia of evolution. The Ancestor’s Tale is not designed to
convince anyone to believe in evolution. It assumes evolution and proceeds from
there. It contributes much to the public myth of evolution as established fact,
and nothing substantive to the defence of evolution against those who are aware
of the fatal cracks in the evolutionary structure.
