“Carl Zimmer is one of the best science writers we have today.” (Rebecca Skloot, author of The Immortal Life of Henrietta Lacks)

We all assume we know what life is, but the more scientists learn about the living world - from protocells to brains, from zygotes to pandemic viruses - the harder they find it is to locate life’s edge.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

Life's Edge is an utterly fascinating investigation that no one but one of the most celebrated science writers of our generation could craft. Zimmer journeys through the strange experiments that have attempted to recreate life. Literally hundreds of definitions of what that should look like now exist, but none has yet emerged as an obvious winner. Lists of what living things have in common do not add up to a theory of life. It's never clear why some items on the list are essential and others not. Coronaviruses have altered the course of history, and yet many scientists maintain they are not alive. Chemists are creating droplets that can swarm, sense their environment, and multiply. Have they made life in the lab?

Whether he is handling pythons in Alabama or searching for hibernating bats in the Adirondacks, Zimmer revels in astounding examples of life at its most bizarre. He tries his own hand at evolving life in a test tube with unnerving results. Charting the obsession with Dr. Frankenstein's monster and how Coleridge came to believe the whole universe was alive, Zimmer leads us all the way into the labs and minds of researchers working on engineering life from the ground up.

Reseñas de la Crítica

“Stories that both dazzle and edify...particularly brilliant in telling the story of DNA.... Zimmer is an astute, engaging writer - inserting the atmospheric anecdote where applicable, drawing out a scientific story and bringing laboratory experiments to life. This book is not just about life, but about discovery itself. It is about error and hubris, but also about wonder and the reach of science.” (Siddhartha Mukherjee, New York Times Book Review)

“[Zimmer] embraces the question of what it means to be alive explicitly and with the enthusiasm of an accomplished and successful storyteller. Zimmer has crafted an eminently readable tale, told through the stories and personal anecdotes of the scientists who have devoted their research to defining the essence of life.” (Issues in Science and Technology)

“The pleasures of Life’s Edge derive from its willingness to sit with the ambiguities it introduces, instead of pretending to conclusively transform the senseless into the sensible.” (The Washington Post)

About 80% of the book talks about the boundary of life and death. The terminal boundary so to speak. Interesting, but I was looking for the initial boundary of when chemical reactions become life. The last 20% explores this pretty well.

I had known about cell theory and auto catalytic reactions. But, the work on assembly theory as a defining criteria was new to me and I like the

This is an easy to understand discussion. A good start for inquiring minds, but you will have to dig deeper for a scientific explanation. I just finished the book and have not looked to see if the references are useful.

Stopped reading when he spoke of Darwin evolution. It is time to move on from 17th century, pre-microscope science. So many scientists have.

I’ve listened to this book several times. It is fascinating and encompasses all aspects of the material

Fascinating and well told

This is fantastic book. I loved listening to it. It is engaging and entertaining thus keeping your attention. I learned so much from it, and I have couple science degrees. I would heartily recommend this book to anyone!

Life at the Edge

I have read/listened to many popular books on evolution, life, consciousness etc., so ai wasn't sure if this would contain enough new material to enjoy. I was wrong.

While any of the concepts and experiments described were familiar to me, the author reports about his talks to the actual scientists themselves about these ideas. The author also switches between the historical development of ideas about life and their scientific underpinnings through out the book. I found it quite enjoyable.

There are many stories of individual scientists and their struggles and triumphs. This keeps the book from being too abstract. The descriptions of the establishment's reaction to various ideas and discoveries about life are fascinating and even insightful of the current status quo.

The concepts and thought experiments are quite engaging on their own as well.

Great tour of science's quest to define life

This book explores the question of "What is life?" and how humanity has studied this idea and the many attempts at creating definitions for life throughout time.

I thought I knew a lot about the subjects discussed in this book, but I actually learned a lot of new history and science from listening to this work. Listening to this work changed some of my long held viewpoints and assumptions on what we know about the origins of life and how extremely difficult it is to even create a definition for life at our present level of scientific understanding.

I'd highly recommend this book to any rational, open minded person, who has ever wondered how much we actually know about the origins of life. There is a lot of very interesting history covered in this book as well, and will explain the state of humanity's understanding through time and how we arrived at the present.

What is Life?

At one time, life seemed easy to define. As we've learned more about chemistry and biology, our once clear definitions seem to have gone the way of the dinosaur. I expected to read a book about life's origin when I started. The book went beyond those expectations. It covers the investigations of proto life in laboratories. It asks what life is through the study of viruses and looks s at the theories of viral origins. The author explores how life arose and diversified and our understanding of the lingering debates about how people have defined the beginnings of a human or an animal life.

A thoughtful exporation on the nature of life

nice collection of stories about various scientists and scientific directions, and very good summaries of a variety of science theories.
But the author is clearly upset that a general term (life) doesn't have a specific definition. He uses water as an example of a specific definition of a general term, which doesn't work, does it? The water (general) coming out of my sink faucet (specific) is very different from the water (general) in the ocean (somewhat more specific). H2O may be a common denominator (and perhaps that's what he's actually looking for in "life") but other specific components are not.
Then there's the inevitable hints of pathological partisanship, presented as "scientific facts" which certainly has nothing to do with science, but "can't" be acknowledged as personal preference.
The author also continually misuses the word "instinct", which becomes scientifically annoying.
Otherwise, enjoyable listen.

Great writer & great narrator. Intriguing & compelling. Most chapters are worth listening to more than once. All the stories & details are woven together nicely & realistically by the end of the book. I highly recommend it.

Science writing for everyone, well done & fun

This is the question you will ask yourself after reading this book. Zimmer gives us just enough information to allow us to formulate our own understanding of life. Thought-provoking!
