Celebrated New York Times columnist and science writer Carl Zimmer presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities...

But, Zimmer writes, “Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are—our appearance, our height, our penchants—in inconceivably subtle ways.” Heredity isn’t just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors—using a word that once referred to kingdoms and estates—but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer’s lucid exposition and storytelling, this resounding tour de force delivers it.

Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world’s best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.

Critic reviews

“Extraordinary...This book is Zimmer at his best: obliterating misconceptions about science with gentle prose. He brings the reader on his journey of discovery as he visits laboratory after laboratory, peering at mutant mosquitoes and talking to scientists about traces of Neanderthal ancestry within his own genome. Any fan of his previous books or his journalism will appreciate this work. But so, too, will parents wishing to understand the magnitude of the legacy they’re bequeathing to their children, people who want to grasp their history through genetic ancestry testing and those seeking a fuller context for the discussions about race and genetics so prevalent today.”—The New York Times Book Review

"Zimmer dispels longstanding scientific misconceptions, introduces facts that may surprise you and brings readers on a delightful journey of genetic discovery."—The New York Times, "Paperback Row"

“Magisterial...In Zimmer’s pages, we discover a world minutely threaded with myriad streams of heredity flowing in all directions, in variegated patterns and different registers.”—The Atlantic

Fascinating target shift

Great genetics historic overview with information shifting for youth to elderly as in popular page turned genres. Entertaining. Informative.

Intriguing Insights

The concept of mosaic inheritance was mind boggling. Also the idea that DNA from my daughter and her father may be lingering in my body is awesome. The exploration of the range of possibilities of how DNA forms each person’s individual sexuality is truly eye opening.

Very informative!

If you like reading research on research, this book in incredibly informative! From the philosophical arguments about heredity to the current science and status of genetic engineering, this book is a thorough and interesting investigation into how we perceive WHAT we are is passed on to future generations. Not only is the scientific significance examined, but as well as the ethical and legal ramifications of these findings.

excellent science writing

I picked this title because I hoped to develop a better understanding genetic heredity. The book delivers a social and scientific history of the concept of heredity: from the development of royal bloodlines and family trees to the rise of racism and eugenics. It was as interesting to learn about this history as it was to delve into the future of gene editing and its moral and social implications. I throughly enjoyed this book.

Amazing overview

Highly recommended. May be too much detail for some but still an excellent resource. Worthy of your time :-)

Good overview of inheritance

Starts off slow with stories that have little to do with inheritance, but I'm glad I stuck with it. Zimmer provides a good up to date research in genentics. A good overview for anyone interested in the study of heredity.

Multiple mind-blowing moments

From history you never imagined to evolutionary quirks you've never heard of, this book is continually mind-blowing.

The Zombie Apocalypse is coming.

I am not a scientist, but I like science books. Though some of this became a bit dry, I still picked up enough that I really enjoyed it. The history of geneticists, and how their ideas & theories ~ interestingly ~ evolved was fascinating! The stories used to explain the science progress, help to make it relatable. This is how genes & our definition of hereditary relates to actual humans (and other animals).

All the "fun" dissipated in the final chapters. Scientists sitting in a corporation's lab, trying to come up with a gene to make insects infertile, or creating a way to make natural conception unnecessary. Corporations do not care about the results of their actions. They ONLY care if it makes immediate profits.

To quote Dr.Ian Malcolm from Jurassic Park,
"Your scientists were so preoccupied with whether they could, they didn't stop to think if they should." The world is a big place, and it's only a matter of time, before we "science" ourselves right out of it.

Enter, Stage right...Zombie Apocalypse.

Zimmer is one of the best popular science writers.

Most scientists suffer from what is known as the curse of knowledge a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand. Zimmer isn't a scientist instead he's an exemplary story teller. He's crafted this abstruse subject matter into a narrative more akin to a story. This is my first book of his that I've read and it won't be my last.
I think one of the biggest challenges for a sweeping story like this for the author is their conclusion or summarization. But in the final chapter Zimmer adroitly pulled the story of heredity in particular and genetics more broadly into a cautionary tale with cause for optimism as well as worry. This is a very good book.

Fascinating in breadth and depth

A fascinating, near encyclopedic. review of history and current state of genetics and heredity. Masterful presentation that manages to convey the highlights and some of the arcana to deepen our understanding of this fundamental and important body of knowledge. of ourselves.
