Nonpareil science writer David Quammen explains how recent discoveries in molecular biology can change our understanding of evolution and life’s history, with powerful implications for human health and even our own human nature.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of t

Meticulously researched, but Quammen’s ability to frame a complex scientific theory in a captivating story is lacking. Pick up The Tangled Tree if molecular phylogenetics is what makes your heart go pitty-pat.
I feel so disappointed. It was like being a kid and getting a half eaten chocolate Santa on Christmas as your only gift. This seems like a book half written. When I got the the end, I just sat there in completely disbelief. Some parts of this book are exceptional. For example, this is an incredibly detailed and informative history of how scientists and the public came to understand the tree of life, how our understanding changed to see it as a web, and finally, merely a starting point with no sh ...more

National Book Award Longlist for Nonfiction 2018. Wow—where to start? Probably the most ‘blow your mind’ thing is that 8% of the human genome originated in virus genomes. This is just one of the insights resulting from scientists studying molecular phylogenetics, where the study of DNA and RNA in different species allows them to discover the evolutionary relationship among them. One such retrovirus genome fragment is found in placentas and helps to transfer nutrients between the mother and child ...more

99th book for 2018.

This is a captivating history of the changing ideas surrounding the evolutionary tree life, from Charles Darwin to the latest findings in computational phylogenetics. Quammen writes really well and the story and it's complications are fascinating. However, the books flowed is damaged as Quammen attempts to write a second book - a biography of Carl Woese - within the first which breaks up the flow and distracts from the central story of the book.

I guess what I really wanted was a magazine article with conclusions. This had much more biographical information than I wanted. Actually, it had much more of everything than I wanted. I assume that I am not the correct audience for this book.

A large part of the book was about Carl Woese, a character who was odd, but about whom I really could not care. He used early, difficult sequencing techniques to identify the Archaea, an entirely separate form of life, different from bacteria, plants, and animals. But since this was already old news when I had Bio 101 in 1990-91, I already knew about the Archaea, and the details of its discovery and identification just weren't that riveting the way they're presented here.

This is a book at war with itself, trying to be many things at the same time. It is a well-written examination of evolution, the inadequacy of the standard tree metaphor for it, and the messiness of gene transfer. Quammen explores horizontal gene transfer and the uncertainty in what a species actually is, what an individual is (with all the little cells that live in us but don't share DNA). This is timely and fascinating stuff.

It is also a biography of, and tribute to, Carl Woese. I hadn't known

"Science itself, however precise and objective, is a human activity. It's a way of wondering as well as a way of knowing. It's a process, not a body of facts or laws. Like music, like poetry, like baseball, like grandmaster chess, it's something gloriously imperfect that people do. The smudgy fingerprints of our humanness are all over it." - David Quammen in The Tangled Tree

In The Tangled Tree, popular science writer David Quammen gives us the history of a field of study called "molecular phylog
I enjoyed the other three books by Quammen that I've read, but had difficulty getting into this one. Seemed like a really hard slog and too focused on material of little interest to me. Bailed after fifty pages or so.

Comprehensive, exhaustive, entertaining, at times gossipy, and altogether wonderful! If more science books were so rich with stories of the scientists, more students might be riveted to classes in genetics and evolutionary biology.

I cannot imagine the years of research that must have gone into the writing of this book. Interviews with authors living or then-living, now-dead, bring to life the drama and controversies and obstacles that beset even a rational scientist. Never mind scientific object

There is no one correct way of dividing a world, identity is fleeting and reification leads to oversimplification. All of that is within this book as the author looks at where the incredibly interesting world of microbiology stands today and what it means for understanding our current understanding of the world we find ourselves in. I have read many stimulating books on the early 20th century development of quantum physics and gravitational theory and this book has that feel to it and lays out t ...more

THE TANGLED TREE. (2018). David Quammen. **.
The extended title of this book was: “A Radical New History of Life.” It kind of sounds like Twilight Zone, doesn’t it. Unfortunately, the author got lost in his list of players to the point where what they discovered became less important that their relative roles played in the discoveries. This was a book about Christmas that focused on all the elves (in a sense) in an attempt to resurrect them from falling into obscurity by people looking at their s

5 stars for how fascinating this theory is and 1 star for the book. The book is just a bunch of short bios about a bunch of scientists from Darwin to the present who have contributed to misunderstanding and then understanding better, the history of evolution. The big breakthroughs are covered at the end and they are huge breakthroughs and super fascinating. But maybe skip the book and listen to the radio lab episode with the author or read the Times review. The good stuff is covered there.

It’s ok but I wish it had more technical details.

The people stories are ok but less valuable than the science

Horizontal gene transfer is a thing!

Often, we learn about science via dense textbooks. They seem definitive. There are illustrations and graphs and chemical reactions and mathematical notations. we often forget that the knowledge therein is provisional. Sure, it's often trivial stuff. Like there being only 8 plantets now, unlike th e9 printed in every textbook printed before 2006 when it was degraded to staeroid status.

But some things are not so trivial. And David Quammen's THE TANGLED TREE tackles a decidedly non-trivial topic: h

A good science book is a wonderful thing, and this is a really good science book. Quammen weaves his story between people and science, following ideas and personalities, discoveries and molecular phylogenetics in a careful balance intended to keep a relatively ignorant audience afloat. I am that audience, coming in with a pretty good grasp on Darwin and natural selection, Lamarck and evolution etc, but with nothing post-1980s high-school regarding archaea, bacteria, eukaryotes and prokaryotes.

4.5 stars; this was delightfully fascinating and I learned so much about micro phylogenetics, which--weirdly--is not a topic I knew much about but am SO FASCINATED BY! Phylogenetics is basically what happened with DNA and genetics PRIOR to what we know as "evolution"...meaning, the species of the world originating from a common ancient ancestor. And also, why does our DNA look the way it does, and HOW!? Well, it's not all natural selection / inherited genetics that are shaped by survival of the ...more

Wow. A lot has changed since I took AP Biology in 1985-6! Back then it was classic Darwin and prokaryotes and eukaryotes, and the reason some bacteria were antibiotic resistant was because they were descended from the few survivors with some random mutation that gave them resistance. ALL WRONG. ALL CHANGED.

This book was absolutely fascinating (if you like history of science) and biology and thinking about how we come to be where we are, biologically speaking. If you've never heard of molecular p

The Tangled Tree is a rich, fascinating tale—not just of the history of evolutionary biology—but of the people behind the discoveries. While the book is primarily focused on Carl Woese and his immense contributions to the field, it weaves in and out of those he worked with, those who influenced him, those he despised, and those who lived long before his time. In that way, the book mirrors the tangled tree it is attempting to elucidate.

David Quammen has written a great book, wrapped in a pretty good one. I rarely give 5-star reviews, and from me a 3-star review actually means "I liked it", just like the goodreads scale advises. Nonetheless, I have given Quammen's books 5 stars on more than one occasion, and never less than 4. Until now.

Keep in mind, 3 stars from me means "I liked it", and I did like it. In fact, there was a 5 star book inside this one, a book about the ways in which a metaphor as old as the idea of evolution i

Let’s start here: Mind. Blown.

Few books I’ve read in my long life have had such a walloping impact. This deserves the National Book Award for non-fiction. It’s that good.

Do you wonder about the origin of life? Evolution? The “whats” and the “hows” more than the “whys”? This is the story of what we’ve learned about how living organisms emerged and grew into the endless variety we have today. It’s a story in which bacteria and a group of living things called archaea became the focus of evolution

This book provides an extremely interesting, enjoyable, and readable overview of the history of the theory of evolution, from Darwin and before, up to the most current ideas. The central figure in the book is Carl Woese, who discovered Archaea, and there are also many engaging mini-biographies of other important figures (Charles Darwin, of course, but also Ernst Haeckel, Lynn Margulis, Ford Doolittle, and several others), and explanations of their contributions to the science.

More accurately biographies of the scientists who made the discoveries.

A riveting account on some of the most important findings related to evolution in microbiology in the 20th and early 21st century. Perhaps because the previous book I read by Quammen, Spillover, was so well writen, I just picked up this one almost without hesitance. Once again, Quammen doesn't disappoint, though I do have a few places I'm not happy with.

As with books on deep history, whatever implications of these scientific works the book discusses will leave readers with plenty of personal phi

Really hard to rate this one. On the surface it should have all of my boxes ticked: phylogenetics, science history, some philosophy, insider insights into how various famous scientists' labs worked, etc. But this just never came together for me the way many of Quammen's other books have. I read it over the course of the semester with my lab, and I think we mostly concurred about its major flaws.

1) We were never able to figure out who the audience was meant to be. On the surface, it's us, surely

The tree of life--the one imaged in the familiar branching diagram pretty much all of us learned as we started to study science--isn't really a tree. It's reticulated, a web with crosses and blurrings at pretty much every level. Check out the images on pages 285 and 299 for ways of imaging the more complicated reality.

It's pretty cool.

And it requires us to revise what we mean by minor terms such as "species" and "individual," neither one of which has any clear reality. It's an idea

I found parts of this book frustrating. In particular, there was extensive discussion on how the Woese lab performed a significant amount of RNA sequencing using Sanger-sequencing. He even wrote out examples including uracil. However, this is misleading. We sequence the DNA, not RNA with Sanger. And while this may have been done to simplify the conversation, it was a pretty big jump to make without explanation.

It seemed like Quammen was trying to do too much. I wish he would stick to the main t

I really waffled on whether to give this book a 4 or 5 - basically, it could have started from chapter 49. The preceding chapters helped to flesh out the phenomenal journey - developing central characters such as Carl Woese, who made the discovery of a third form of life - but it was lengthy.

But, I reiterate, how phenomenal this journey is. It should be required reading for biology/philosophy/history students. My mind was buzzing with new information and new dots to connect to other information

This book reviews the ideas of the Tree of Life from it's origin with early thinkers, primarily Darwin, through the understanding that the Bacteria and Archaea form separate domains.

The book also has a number of secondary themes. The life of Carl Woese, who was largely responsible for the discovery of the Archaea as a distinct domain, is covered in detail (and notably in the concluding chapters).

The discovery of horizontal Gene Transfer (HGT) is a major theme in the second half of the book. HG

David Quammen (born February 1948) is an award-winning science, nature and travel writer whose work has appeared in publications such as National Geographic, Outside, Harper's, Rolling Stone, and The New York Times Book Review; he has also written fiction. He wrote a column called "Natural Acts" for Outside magazine for fifteen years. Quammen lives in Bozeman, Montana.
“Habitat doesn’t replicate itself. Places get crowded. Creatures go hungry. They struggle. The result is competition and deprivation and misery, winners and losers, unsuccessful efforts to breed and, for the less fortunate individuals, early death. Many are called, but few are chosen. The book that awakened Darwin to this reality was An Essay on the Principle of Population, by a severely logical clergyman and scholar named Thomas Malthus.” 1 likes
