The ancestor's tale : a pilgrimage to the dawn of evolution

by Richard Dawkins

Paper Book, 2004




Boston : Houghton Mifflin, 2004.


The renowned biologist and thinker Richard Dawkins presents his most expansive work yet: a comprehensive look at evolution, ranging from the latest developments in the field to his own provocative views. Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism. Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.… (more)

Media reviews

Beginning with modern humans and moving backwards in time, he describes our lineage as we successively join — a geneticist would say coalesce — with the common ancestors of other species. Human evolution has involved 40 such joints, each occupied by what Dawkins calls a "concestor", and each is
Show More
the subject of a single chapter. He begins, of course, with our common ancestor with chimps, followed by the concestor with gorillas, then other primates, and so on through the fusion with early mammals, sponges, plants, Eubacteria and ultimately the Ur-species, probably a naked molecule of RNA. This narrative is engagingly written and attractively illustrated with reconstructions of the concestors, colourful phylogenies, and photographs of bizarre living species. The book is also remarkably up to date and, despite its size, nearly error-free. Especially notable are Dawkins' treatments of human evolution and the origin of life, the best accounts of these topics I've seen in a crowded literature.

While I read different genres, I only review books with a religious content. So, if I may be excused for one of my “liberal Christian rants,” let me say this: It’s a sad day when a book about evolution earns a spot on the shelves of a religion blog. It simply astounds me that half of all
Show More
Americans still do not believe in evolution. The evidence is so overwhelmingly against a young earth that if Christianity is going to survive, it must pull its head out of the sand and reinterpret the Bible’s creation story (anything but a literal interpretation!) before it alienates the coming generation, who will simply know better.

This book will help. I’m not a fan of Dawkins’ anti-religion tirades, but when he sticks to his evolutionary biology, his writing is a pure delight. It’s insightful, highly intelligent, and witty. The subtitle of the book is A Pilgrimage to the Dawn of Evolution, and it’s a long journey backward in time from present-day humans to the beginnings of life four million years ago.

You’ll meet Cro-Magnon man, the Neanderthals, chimpanzees and gorillas, monkeys, rodents and rabbits, reptiles, sharks, flatworms, sponges, fungi, plants, and far more, each with their own unique role and story to tell.

Scientific understanding is, and ever will be, in a state of transition. As we learn, we shape our theories to fit the facts. It’s an exploration that never ends, an exciting quest for truth that Dawkins excels in sharing. He stops often along this journey back in time to introduce interesting life forms and their evolutionary sidebars, evoking wonder and appreciation for the real creation story that far exceeds any ancient tales. It’s such a treat that I’m almost envious of long-time creationists who can, by opening their minds and turning the cover of this book, open themselves up to a new world of wonder.

You will see the world in a different way after reading this.

This is what high school biology *should* be like! Biology is really not taught as a science at that level, with theories, and hypotheses, and the underlying theme of evolution. Instead, we spent years memorising and regurgitating useless facts about various animals, some more interesting than
Show More
others; but there was always something missing - it was always just facts, without a guiding theme or overall connection.

Dawkins gives us the facts, alright - but he does so with a purpose, around the central theme of evolution, showing how life on earth is all interconnected, and that's what really makes the subject fascinating. Suddenly, biology *makes sense*! There's a story to go with the facts, and that story makes the previously meaningless collection of data seem absolutely amazing, revolutionary and eye-opening! It certainly helped me for the first time really appreciate both the complexity and interconnectedness as well as the pure awesomeness of life on earth.

Obviuosly, what with Professor Dawkins being a zoologist, the book is heavily focused on animals, and as the "journey" starts with humans, a lot of the book is devoted to vertebrates. I would happily read another book that size about exciting things like insects, invertebrates and plants!

There are some facts the simple knowing of which seems to me to be a supreme achievement of our species. The fact that we are all made of stardust. The fact that 99.9999999999999 percent of all matter is empty. The fact that mass and energy can be expressed in terms of each other. Stuff like
Show More

Pre-eminent among these to me, for sheer mind-expanding awe, is the fact that life on this planet has developed precisely once, as far as we know, and everything on earth has evolved from it. That means that when you go outside and lie down in the garden, everything you can see and hear – people walking nearby, their pet dogs, the squirrel darting past, the birds you can hear tweeting, the insects and tiny bugs crawling around underneath you, the trees the birds are standing on, the grass you're lying on, the bacteria in your guts – all of them are your cousins: you're quite literally related to them in the real, genealogical sense.

If you go far enough back in time, in other words, you will eventually find a creature whose descendants evolved into both squirrels (say) and people. Indeed, the rules of heredity being what they are, you could even find a single individual who was a common ancestor to every squirrel and human alive. And indeed such an animal really did exist, around 75 million years ago in the Upper Cretaceous. It probably looked sort of mousey, and Dawkins estimates that he or she was our ‘15-million-greats-grandparent’. Squirrels are not ‘closer’ to this creature than humans are: we and they are equally related, having been evolving independently for the same amount of time.

The Ancestor's Tale takes exactly this approach to exploring evolution. It starts with humans and works backwards – looking first at the common ancestor between humans and chimpanzees, and continuing until we reach the common ancestor of all life on earth. Dawkins's word for a common ancestor of more than one species is ‘concestor’, and there are only about 40 of them (!) between us and the origin of life more than three billion years ago. The Cretaceous mammal I mentioned above, which evolved into us and squirrels (along with all the other rodents, lagomorphs and primates), is Concestor 10 according to this schema.

I think there's a lot of traps you can fall into when you start thinking about evolution. It's easy to feel, instinctively, that evolution is somehow teleological: that it's been working towards – if not us, then at least creatures that are increasingly complex and increasingly intelligent. But that of course is not the case. Things survive that reproduce themselves well, and there are plenty of single-celled organisms still with us that have seen no need to get any more complicated for millions of years. Bacterial life is in fact astonishingly varied and rich, whole phyla of creatures that branched off before multicellular life even came about; indeed, chemically speaking,

we are more similar to some bacteria than some bacteria are to other bacteria.

Just think about that for a second.

Before Dawkins got distracted by religious idiocy, he was well known as being one of the scientists most able to explain complicated ideas in a fresh and accessible way. All his skills are on display in this work. It's not just the zoology and the evolutionary biology, where you'd expect him to be strong; there's also a fantastically lucid explanation of the biochemistry within a cell, and even one of the best explanations of the physics of radioactivity that I've come across. He is calm and careful; he repeats himself where necessary; he shares several teacherly witticisms; and he does all this without ever condescending to the reader. He allows paragraphs of complex material to sit, so that you can read and re-read them a few times before he carries on. Occasionally he cannot stop himself breaking out in exclamations of wonder or poetic meditation – as when he discusses the fossilised footprints of three early hominids from some three-and-a-half million years ago:

Who does not wonder what these individuals were to each other, whether they held hands or even talked, and what forgotten errand they shared in a Pliocene dawn?

His enthusiasm is infectious. The whole book is a fantastic exploration of this most beautiful piece of modern human understanding. It's full of astonishing anecdotes and scientific details about the natural world, but it also all ties together into a conception of life that's more awe-inspiring and more moving than any supernatural system could ever be.

A detailed look at evolution and the history of animal life of Earth. The style is modelled on Chaucer's Canterbury tales. For reasons's that become clear Dawkins, retraces the ancestors of the human specis through a series of "Concestors" - a species that was alive and whose descendants evolved
Show More
into different branches of "the tree of life" the style is very clear, without use of overly complicated termiology - resulting in at times a simplistic overview, though this is usually acknowledged.

Because the initial lineage chosen is human, the drawback to this journey is that several major groups diverged from us so long ago, that entire interesting groups are given only a page or two's treatment. The entire plant kingdom gets only a chapter.

Various nominated species are chosen at each concester point to give Tale - and like Chaucer's original work - each tale has a point, not necessarily on evolution, some worthy commentary on the accompanying science, assumptions etc are made. Unfortunetly the science of dating the various records is left until the Redwood's tale, more than 3/4 of the way through the book.

Some of the personal commentary from dawkins is more belivable, and given more evidence, than others. Sometimes he states his opinion is contentious, but in my view, there is room for more doubt than he sometimes credits.

Overall it is a worthy tour through the history of the animal kingdom, back to the origin of single celled entities at the dawn of time - but missing much detail that could be covered. A useful reference rather than a detailed guide.

This is a book on evolution with a twist. Rather than start at the earliest history of life and trace evolution bacl to the modern man, Richard Dawkins travels the other way. He takes us back on an imaginary journey in time trying to trace who might our ancestor have been, arguing his case with
Show More
evidence. He calls this a pilgrimage to the dawn of life, and just like Chaucer's pilgrim, in Canterbury Tales, met a number of interesting characters on the way, we too meet interesting creatures like the starfish with its piped hydraulic power, the migrating jelly fish with tiny harpoons, the platypus with its radar of a beak and many more. A fascinating journey, though sometimes a bit meandering than it needed to be, that will definitely open our eyes to the broad and sweeping vista of life on earth.

Dawkins takes his readers on an imagined journey back through time, tracing our evolutionary history by visiting the milestones that mark our common ancestry with other modern species as they make their own backwards voyages. At each such meeting, he focuses on one or more of these fellow
Show More
evolutionary pilgrims as a jumping off point to discuss some aspect of evolution.

It's a terrific premise for a book, though in practice I think it ends up being a little bit of a mixed bag, as this structure inevitably makes the whole thing a little bit disjointed. We jump around from topic to topic, with the subject of any particular "tale" often only very tangentially related to the animal that has supposedly inspired it. Sections describing very basic tenets of evolutionary theory are interspersed with others that are possibly more fiddly and technical that the average reader really needs, and concepts alluded to in early chapters may sometimes not be properly introduced until late in the book.

However, all that being said, it's also true that any time I started to find things a little bit tedious, Dawkins would suddenly wow me with an absolutely fascinating set of discussions, ideas or facts, written with great enthusiasm and clarity, and get me all excited again.

I also have to praise Dawkins' thoughtful precision here. He's always very, very careful to make sure that readers are not confused or misled by scientific jargon or by figures of speech, and he is also conscientious about acknowledging what the various alternative hypotheses are when some fact or concept is subject to scientific dispute. Less praise-worthy is his occasional jarring indulgence in political snark in contexts where it really doesn't belong, but fortunately there are only a few small examples of that.

What an odd book. At times it's written for beginners and other times for folks with a bachelors in biology or some other science. I listened to the audiobook version and it has two narrators, Dawkins and Lalla Ward, and they switch back and forth mid-paragraph, without reason, making it extremely
Show More
difficult to follow. In some cases they switched mid-sentence almost word for word back and forth, strange and completely distracting. I've never heard an audio production like this before and probably never will again, it was not successful. I also found the frame-tale around Chaucer to be gimmicky, what does Chaucer have to do with biology and evolution, there's no depth to the analogy other than a surface comparison of going on a journey, might as well have chosen The Wizard of Oz and the Yellow Brick Road. No doubt there is good stuff here but it comes and goes, and sometimes I zoned out among the invention of the wheel by bacteria. Probably the one thing that I will remember long term is the idea of a "ring species", very cool.

Better known for his "The God Delusion" and his aggressive atheism, this book is actually what Dawkins does for a living: good science, well-described. But it is like no other science book. He works his way back down (up?) the tree of life, identifying each significant branching, and uses as his

I think this is Dawkin’s best book so far (I haven’t read The Greatest Show on Earth yet). I probably don’t need to explain too much about Dawkin’s writing style; his atheist polemics are somewhat tempered here – because what he’s talking about is so interesting that he doesn’t have
Show More
time to jump all over the religious.

The basic theme of the book is a tracing evolution backward, in a series of “rendezvous”. At each rendezvous, another group of living things “joins” (and the phyletic level of the joining group gets broader and broader); chimpanzees, rodents, monotremes, sauropsids, lungfish, ctenophores, all the way back to eubacteria. This is the reverse of the normal evolutionary explanatory method, in which groups “split” as you go forward in time rather than “joining” as you go backward. It works quite well, because it emphasizes similarities rather than differences. There are little natural-history anecdotes at each “join”, which illustrate some aspect of the joining group’s biology; as a collection of essays, the book would be worth it for these alone.

Of personal importance to me is I’ve finally been dragged kicking and screaming out of my final death grip on phyletic systematics. I grew up with – Mom read it to me before I could read myself – The Golden Treasury of Natural History, which was a profusely illustrated children’s book covering everything from the origin of the solar system to modern biology – modern for 1953. There was a double page multi-colored spread of the Great Tree of Life, with things neatly divided into Mammals and Birds and Reptiles and Amphibians and Fish and so forth for the invertebrates. And in Mammals things like Odd-Toes Ungulates and Armadillos and so forth. All that’s gone now – “Fish”, in particular, has been known to be polyphyletic for years (in cladistics terms, a cow is more closely related to a coelacanth than a shark is; back then they were all “Fish”. Well, not the cow).

That means Dawkins springs a bunch of new groupings – Laurasiatheria and Sauropsidia, for example, and Ambulacraria - that I have to puzzle over. Everything I learned as a budding taxonomist is wrong. It’s wonderful.

I can´t remember having read (listened to) a book that has taught me so much, while at the same time having been so entertaining, illmuniating, brilliant - and irreverent. Richard Dawkins is a brilliant narrator, and he manages to make the history of evolution come alive. At the same time HE comes

alive, because his personality, his visions and outlook on life breathe from every page. He is so compassionate about his subject area that no-one can come away from this book without feeling awed. There is a sense of wonder in The Ancestor´s tale that sadly is missing from his God Delusion, even though he can be as scathingly hard to his scientific enemies as to his religious.
Is Richard Dawkins the People´s Scientist? Yes, I believe so. More than Stephen Hawkins he makes the reader understand (although I probably have to read the book at least once more to understand most of it, but I am not a scientist). At times the book is a bit too long and detailed, but keep reading (listening), it always gets better.

It's like a trip down a river: you start on a narrow stream in a village high in the catchment and go through your community first (human evolution). By the end you are in a river several kilometres wide and the influx of major tributaries (fungi, plants) is barely noticed. It is perhaps not surprising that the best parts are the start, on the great apes, and the end, on the origin of life and Dawkins' ideas about watersheds in evolutionary "progress".
