The Tree of Life: Solving Science's Greatest Puzzle
'A DELIGHT' HENRY GEE
'BEAUTIFUL' THOMAS HALLIDAY
Where do we come from and how did we get here?
Come time-travelling through the history of every species that has ever lived with Professor Max Telford.
A four-billion-year journey through the evolution of our planet, The Tree of Life tells the fascinating story of the gigantic family tree that records the relationships between every living thing - from humans, fish and butterflies to oak trees, mushrooms and even bacteria.
Understanding how the amazing diversity of life on earth came to be is one of the greatest puzzles in biology. And this book, full of vivid and fascinating stories, takes you right learn why grey wolves are more closely related to whales than to Tasmanian wolves; how geological change and environmental catastrophe left their marks on the genome; why we don't have tails but we are the only species with chins; and follow individual scientists down winding evolutionary byways and occasional dead ends in their attempts to solve this greatest of all puzzles. Along the way, we'll see how, far from being a dry representation of the dead, the tree of life is a living thing which constantly alters our perspective on the past, present and future of life on earth.
From Darwin's early sketches to the vast computer generated diagrams scientists are building today, The Tree of Life explains how we can know our family tree at all and tells the epic history of the various ways it's possible to be a living thing. This is our own very personal story that began with the tiny ancestor of all life billions of years ago and ends with you and me.

Examining the biological relationships that connect humans to everything from birds to bacteria, and our millennia-long quest to make sense of how Earth's organisms are related, THE TREE OF LIFE narrates its subject in accessible, amusing language, with asides mentioning how Mendeleev's life "reads like a Dostoyevsky novel" or the author's own mistakes in the laboratory enlivening this topic. I was also impressed by Telford's ability to explicate technical concepts in straightforward language, such as a breakdown of the principle of parsimony that gets its point across in a few paragraphs and a diagram.
However, the episodic nature of this book, with each chapter typically honing in on one biological case study or question that relates to the wider topic of Earth's genetic tree of life, means that I sometimes lost the thread of Telford's analysis between chapters. I wonder if a clearer sense of the book's logic could have been created by capping each chapter off with a mini-conclusion, indicating how it feeds into the wider questions of the book or links with the preceding or succeeding chapter.

I thought this book was fantastic, accessible to those like me with not much of a science background. I learnt so much!

momentami fascynująca, dużo częściej niezrozumiała, zdecydowanie bardziej naukowa niż popularnonaukowa

This was an extremely interesting book, although I can’t say that it was an easy read for me; I think I was coming to it about 55 years too late. I struggled with the scientific language, although I appreciate that the author did a great job of making the concepts of evolutionary biology as accessible as possible for the lay reader. His style was engaging and at times amusing, and I appreciated the personal touches about his own research. This gave an insight into the controversies and academic disagreements that added a human touch to the book, especially around the chapter ‘The Diet of Worms’, where the author describes ‘the story of…the acoelomorphs and Xenoturbella…where I will indulge myself by talking about these and some lesser-known worms that have been my passion for more than thirty years.’
I doubt I will be able to retain much of the scientific information, but there is also a good deal of interesting history of the development of the study of evolution and the impact of genetics. The most impressive aspect I do take from this read is timescales; when you come to a chapter entitled ‘The first three billion years’ it does take the breath away, especially when compared to the traditional estimate of human lifespan as three score years and ten. Then there are the aspects of scale in the size of the organisms being researched, and our ability to examine microscopic forms of life. And again, on the question of the number of species in existence today:-
‘Conservatively…at least 8 million species alive today are unknown to us - the great majority in fact.’
Finally I suppose what made the most impact for me was the philosophical aspect of evolution: from page 203 of the hardback edition:-
‘The humbling reality is that evolution has no aim; the evolution of humans had no inevitability at all, and our path up the tree could have been snuffed out on a billion different occasions…on the vast scale of the tree of life, our species is a single leaf, a very recent arrival, and one that may not be around for long.’ Hence Shelley in ‘Ozymandias’
“ ‘Look on my Works, ye Mighty, and despair !’
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.”
And finally, from the last chapter ‘Unknown Unknowns and the end of the affair’ - ‘We can make one safe prediction, however: the only real certainty for the future of the tree of life on earth is that it will one day stop growing.’ But after all, what a tree it is!

A fascinating, witty, and crystal-clear tour through animal evolution
The Tree of Life by Max Telford is an outstanding, entertaining introduction to how biologists unravel the evolutionary relationships among animals. From our microbial ancestors to the rise of apes, Telford guides us through billions of years of diversification — not as a straight line, but as a branching, growing tree.
What makes this book special is its clarity and nuance. Telford avoids the trap of telling a “march of progress” story. Instead, he presents evolution as a dynamic process, where species split and diversify over time. He’s refreshingly honest when discussing controversies (especially those he’s personally involved in), and he explains scientific methods — from comparative anatomy to genome analysis — in a way that’s accessible and compelling.
The writing is fluid, full of great examples, occasional British wit, and always grounded in solid science. I learned a lot and enjoyed it thoroughly. Whether you’re new to evolutionary biology or have a background in the field, this is a highly recommended read that delivers both depth and clarity.
If you’re curious about how scientists uncover the relationships among animals, and how life evolved into its incredible diversity — this is the book for you.

I absolutely loved The Tree of Life and would urge all to read it. As a non-expert, I was somewhat daunted by the subject matter but the author makes complex material wonderfully accessible, and his enthusiasm for his work is deeply infectious. I was completely gripped by the Tree of Life's narrative tracking human and all animal life back to common ancestors across the history of planet earth. This is an important book: like all excellent science writers, the author has gifted his reader the chance to understand four billion years of evolutionary biology in a way which may have felt out of reach to a layperson. And, incredibly, he is laugh-out-loud funny while doing so.
A beautifully thought through and well-constructed account of how all life on earth is connected (and why worms are important!). It deserves a wide audience.

A bit of a disappointment. Perhaps this results from my ignorance of the complexity involved in the author’s research and subsequent thesis. I think this book could have been much better written and subsequently easier to follow had Dr Telford relied upon a ghost writer to convey his philosophical ideas. It also appeared to be chock full of assumptions that if a reader were not careful could presume that the author is presenting scientific fact instead of philosophical assumptions. E.g. the idea of LUCA was intriguing but lacking in valid/reliable hypothesis testing?

Fantastic time-travel journey to the origin of life! Entertaining and enlightening, I thoroughly enjoyed reading this well-written book. Clearly the result of an impressive amount of research, yet skillfully delivered in an accessible way to the non-scientific reader. Well done and highly recommended to any reader with an interest in the topic, from the age of 10 and up.

Anybody with an interest in evolution will find this book invaluable. The author guides the reader through eons of evolution, from amoebas to humans, noting the links between all species, large and small, in straightforward terms that any layman can understand. Probably the most fascinating book on evolution I have ever read.

I enjoyed this book. The history of science aspect was great, along with the conversational tone, good explanations including the use of analogies, and the great pacing. I loved the author’s journey and some of the anecdotes had me laughing. The tone was highly conversational and this was a fun read. Thank you to Edelweiss and W. W. Norton for the digital review copy.

The book was brilliant! The topic is very close to my own field of work, yet I still found myself learning so much from its historical context, examples, and analogies. It makes complex genomic and evolutionary ideas both accessible and engaging, encouraging experts and non-experts alike to pause, see things differently, and feel able to explain them to others.
