ABOUT THIS BOOK

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs—they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken—imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time in order to witness the process of domestication. This is the extraordinary, untold story of this remarkable undertaking.

Most accounts of the natural evolution of wolves place it over a span of about 15,000 years, but within a decade, Belyaev and Trut’s fox breeding experiments had resulted in puppy-like foxes with floppy ears, piebald spots, and curly tails. Along with these physical changes came genetic and behavioral changes, as well. The foxes were bred using selection criteria for tameness, and with each generation, they became increasingly interested in human companionship. Trut has been there the whole time, and has been the lead scientist on this work since Belyaev’s death in 1985, and with Lee Dugatkin, biologist and science writer, she tells the story of the adventure, science, politics, and love behind it all.  In How to Tame a Fox, Dugatkin and Trut take us inside this path-breaking experiment in the midst of the brutal winters of Siberia to reveal how scientific history is made and continues to be made today.

To date, fifty-six generations of foxes have been domesticated, and we continue to learn significant lessons from them about the genetic and behavioral evolution of domesticated animals. How to Tame a Fox offers an incredible tale of scientists at work, while also celebrating the deep attachments that have brought humans and animals together throughout time.

REVIEWS

“Dugatkin and Trut have collaborated to produce a well-written and engaging account of one the most influential biological studies ever: the fox farm experiment. Over sixty years ago, a Russian geneticist dared to start an experiment to see if foxes could be domesticated and what variables contributed to the changes domestication brought. The courage involved in starting such an experiment in the USSR of the 1950s was remarkable; the dedication and curiosity that have kept it going ever since have led to stunning new insights on the mechanisms of domestication. Every biologist should read this book!”
— Pat Shipman, author of "The Invaders: How Humans and Their Dogs Drove Neanderthals to Extinction"

“An excellent book. The writing is clear and makes for fascinating popular science. This book will attract a wide audience, and I know of none other with such a dramatic combination of good science and social history.”
— Aubrey Manning, coauthor of "An Introduction to Animal Behaviour"

“Over the course of decades, Russian scientists transformed wild foxes into friendly pets. They used no science-fiction genetic engineering. They simply guided evolution. This landmark experiment tells us some profound things about domestication, behavior, and ourselves. Finally, someone has written a book-length account of the experience—and a fascinating one at that.”
— Carl Zimmer, author of "Evolution: The Triumph of an Idea"

 “In the first book on the famous ‘Siberian fox study,’ this extraordinary chronicle recounts one of the world’s most important animal studies. It has not only provided stunning insights into how domestication works and how fast it can happen. It also helps us understand the origins of our deepest non-human bonds—our friendships with our dogs—and where and how they came into being.”
— Carl Safina, author of "Beyond Words: What Animals Think and Feel"

“Can new kinds of animals be brought into being outside of DNA tinkering and Frankensteining? Most certainly, as a long-running Russian experiment reveals. . . . The science is profound, but the authors write accessibly and engagingly—and their vulpine subjects are awfully cute, too. Of compelling interest to any animal lover and especially to devotees of canids of all kinds.”
— Kirkus Reviews, starred review

"This intriguing, well-written account of an ongoing experiment in canid domestication should delight readers interested in the origins of the human-animal bond."
— Library Journal

"Our furry companions evidently descended from wild wolves—resulting from thousands of years of human selection. Nearly sixty years ago Russian researchers Trut and Dmitri Belyaev decided to domesticate wild foxes to learn in detail how the journey from wild beast to household pet happens. They set up their experiment on a farm in Siberia and over the following decades mated the tamest animals from each successive generation. In this book, biologist and science writer Dugatkin and Trut recount this grand experiment. The result: a host of docile foxes and the identification of the genetic underpinnings for their domestication.”
— Scientific American

"A cheerful, easy-to-read account that expounds upon the wonders of scientific achievement. . . . The authors weave other charming histories of other scientific studies and events throughout the book, including the discovery of hormones, pedigree analysis, animal communication, human evolution, and Belyaev's travels in international scientific circles. Writing a simple, straightforward narrative suitable for lay readers, Dugatkin and Trut spin complex genetic science into a fascinating story about adorable foxes."
— Publishers Weekly

"It’s a story of science. . . .But it's also very much a human story. . . . It's a story of persistence against all odds."
— The Hoopoe, NHBS

"Dugatkin is a veteran science writer with a knack for turning sprawling subjects into compact, enjoyable narratives. Trut, now in her 80s, is both a coauthor and a subject of the book, an unusual arrangement. But her intense participation adds a rare degree of intimacy to this science story."
— Wall Street Journal

"Trut and Dugatkin lovingly recount some of the experiment's milestones, including the first fox born with a wagging tail and the first one with droopy ears. . . . At every step, the authors skillfully weave the science of domestication into the narrative of foxes becoming ever-more doglike."
— Science News

"A story that is part science, part Russian fairy tale, and part spy thriller. . . . Sparkling."
— New York Times Book Review

"It is an extraordinary story, and How to Tame a Fox tells it well. . . . By the end of the book, the thesis that wolves may have been no less complicit in the process of their domestication than humans has come to seem entirely probable."
— Times Literary Supplement

"Written for a general audience, it chronicles the story of a scientific gambit that was more successful that even its creators had dreamed. It's an inspiring reminder of how much we still don't know about the world, and how much can be learned by taking bold chances. It's also a cautionary tale about the risks of state-funded science that has nearly as much relevance to Trump's United States, where federal research budgets are in danger of being slashed right and left, as it does to Stalin’s Russia."
— Los Angeles Review of Books

"Written in an accessible style, How to Tame a Fox provides a general reader with an engaging summary of the fox experiments and the people who carried them out. . . . It would make a good book to assign to undergraduate studying the social dimensions of science."
— Studies in History and Philosophy of Biological and Biomedical Sciences

"Celebrates his [Belyaev’s] original insights, his tenacity, and the amazing leadership and hard work by Trut and her dedicated team. . . . Written in a highly accessible style, it is appropriate for both scientists and nonscientists."
— Quarterly Review of Biology

“A delightful history. . . . Recounts the story of the experiments in a very readable and non-technical way, while relating the work to genetics, ethology, evolutionary biology, and the spotty history of Soviet science in the mid-twentieth century. A photo section of the domesticated foxes is guaranteed to touch even the most serious reader. Recommended. All readers.”
— Choice

"Intelligent, accessible, and engaging. It’s a story of courage as well as genius, and a reminder of the enormous value of a scientific curiosity."
— Chapter 16

"I have always felt that scientists err in speaking only about the products of our research and fail to communicate and discuss the process by which we create those products. We quite deliberately bury under the carpet the sources of our hypotheses, the reasons for our choice of problems to investigate, the circumstances and constraints under which we conduct our work and the biases that inevitably creep into our interpretations. Sadly, the scientific literature is sanitized to remove all traces of the human, social, and political milieu in which we practice our craft. This creates an opaque wall between science and society, leading to avoidable misunderstanding and mistrust. How to Tame a Fox is the perfect antidote to this lament. It lays bare all the social and societal influences that relentlessly work during the course of scientific research. And yet, contrary to what many scientists fear, there is not a blemish on the rigor and precision with which the science is described."
— Proceedings of the Indiana Academy of Science

"If you read only two biology books this year, this is one of those two that you simply must read."
— GrrlScientist, Forbes

“Profound insights into how dogs evolved from wolves come from a remarkable, multidecade experiment on foxes that was carried out under the supervision of the Russian geneticist Dmitri Belyaev from the 1950s onward. Because much of the research was published in Russian, How to Tame a Fox, which is cowritten by Trut—a central figure in the project over many decades—will be widely welcomed for the extraordinary detail it contains.”
— Tim Flannery, New York Review of Books

"Do you like charming memoirs about people’s relationships with endearing animals? Do you like expansive, dramatic accounts of evolution in action? Do you like hard-nosed, laboratory-based studies of animal development? Then you’ll love this book, which contrives to combine all three approaches in its account of some groundbreaking studies in animal domestication, begun in the Soviet Union by coauthor Trut and her boss Dmitri Belyaev in 1959. . . . Trut, in collaboration with Dugatkin, a US evolutionary biologist, captures both the charm of her life’s work and the brutality of all those Siberian winters in a book full of delights both intellectual and human."
— Simon Ings, New Scientist

How to Tame a Fox (and Build a Dog) is for the scientist, the historian, and the mystery lover in us all. Understanding domestication reveals much about our own humanness, and the story illustrates many versions of humanity, too.”

[domestication;foxes;Pushinka;Trut, Lyudmila]
In the prologue the reader is given a taste of the silver fox domestication experiment by being introduced to Lyudmila Trut and a remarkable tame fox named Pushinka (little ball of fuzz). A vignette is presented of the first few days they live together in an experimental house that they share for years on an experimental fox farm in Siberia.

[pilot experiment;tameness;Central Research Laboratory on Fur Breeding Animals;Belyaev, Dmitri;Lysenko, Trofim]
Chapter 1 introduces the reader to Dmitri Belyaev, the brilliant Soviet geneticist who first conceived the silver fox domestication experiment. The chapter begins in 1952 with Belyaev laying out the idea for a pilot experiment in Estonia, and then steps back to Belyaev’s early life, including his training in genetics, his days as a researcher at the Central Research Laboratory on Fur Breeding Animals in Moscow, his battles with a charlatan pseudo-scientist named Trofim Lysenko, and the development of his key insight that the answer to all of the puzzling questions about domestication centers on the essential defining characteristic of all domesticated animals—their tameness.

[Trut, Lyudmila;Institute of Cytology and Genetics;Novosibirsk;Lesnoi fox farm;fire breathing dragons;Laska the fox;Kisa the fox]
Chapter 2 centers on the early years of the silver fox domestication experiment, including Belyaev’s move from Moscow to the fledgling Institute of Cytology and Genetics in Novosibirsk (the largest city in Siberia). Just before he leaves Moscow, he meets with an undergraduate student, Lyudmila Trut, who has expressed interest in joining his research team. Soon Lyudmila and her family too are in Novosibirsk, and she and Belyaev begin their lifelong collaboration on this work. Each generation she will select those foxes that were most friendly to humans to parent the next generation. Initially there is no experimental farm at the Institute of Cytology and Genetics, so Lyudmila spends months each year selecting the tamest foxes at a giant commercial fox farm called Lesnoi, a 225-mile ride southwest of Novosibirsk. With the exception of two foxes named Laska and Kisa, for the first few years, Lyudmila finds herself surrounded by what she calls “fire breathing dragons.” But that soon changes in dramatic ways.

[Ember the fox;elite tame foxes;tailing wagging;hand licking;destabilizing selection;human-fox bonds]
Chapter 3 walks the reader through some of the remarkable changes that Belyaev and Trut uncover after just a handful of generations of breeding the tamest foxes. We meet, among other foxes, Ember, the first fox to wag her tail in ecstasy when Lyudmila approaches her. By the sixth generation, the domestication experiment has produced “elite” foxes, that not only wag their tails, but whine for human attention, and sniff and lick human hands. Belyaev begins to develop his theory of “destabilizing selection” to explain these remarkable changes, and because of the progress they are making, he is able to secure space at the Institute of Cytology and Genetics for an experimental farm where they can continue the experiment. And Despite Lysenko’s ban on genetics, Belyaev is starting to tell the story of this amazing experiment at conferences both at home and abroad. While all of this is happening, deep bonds are forming not only between Belyaev, Trut and the team of researchers and caretakers they work with, but between this group and the tame foxes.

[Pushinka the fox;Dream the fox;Encyclopedia Britannica;floppy ears;travels to Scotland;travels to The United States]
Chapter 4 tracks the fox domestication experiment as it moves into its second decade and the tame foxes continue to display new traits. Lyudmila introduces Dmitri to a tame fox named Dream, who has dog-like floppy ears. His response: “And what kind of wonder is this?!” Tame foxes are displaying more mutt-like coat colors, and some even have a white star on their forehead (another trait seen in many domesticated animals). Belyaev is soon lecturing on all the dog-like characteristics of the tame foxes at major conferences on behavior and genetics in Scotland and the United States, as well as authoring an Encyclopedia Britannica entry on “domestication.” This chapter marks the return of the elite fox first mentioned in the Prologue. Pushinka and Lyudmila are poised to embark on a remarkable adventure


DOI: 10.7208/chicago/9780226444215.003.0005
[Pushinka the fox;loyal foxes;house experiment]
In Chapter 5, Lyudmila makes a bold proposal to Belyaev. She wants to move into a small experimental house on the fox farm with a pregnant Pushinka to see how domesticated foxes respond to living with humans the way that dogs do. Dmitri loves the idea, and for next two plus years Lyudmila, Pushinka and Pushinka’s descendants live together, day and night, with Lyudmila taking detailed notes on the behavior of these foxes. Adventures abound, including one evening when Pushinka defends Lyudmila from putative danger by attacking and barking at an intruder.

[hormonal changes;neurobiological changes;International Genetics Congress;out-of-season births]
In Chapter 6 we join the 3,462 geneticists who attended the International Genetics Congress in Moscow in August of 1978. Belyaev and his team run the conference, which not only announces to the world that Lysenko’s ideas are dead and gone forever, but introduces the world’s leading geneticists to the new findings that Dmitri and Lyudmila have discovered in their tame foxes. This chapter also discusses the hormonal and neurobiological underpinnings of the changes to the tame foxes that had been going on since the start of the experiment. Part of this work centers on Belyaev’s hypothesis that domesticated species often break the once-a-year reproductive cycles seen in their ancestors, and the tame foxes might eventually do so as well. And indeed, a handful of foxes do mate and give birth twice a year. “Here are results you should be proud of,” Dmitri proclaims as he announces the births. “Here are results you can boast about.”


DOI: 10.7208/chicago/9780226444215.003.0007
[Coco the fox;self domestication;death of Belyaev]
Chapter 7 opens with the heartwarming tale of Coco the tame fox, so sickly at birth that she is adopted by one of the fox team members and her husband, who just want to give little Coco a place to die in dignity. Coco surprises everyone by not only surviving, but thriving, and forms a deep bond with her adopted human father, Galya. Chapter 7 also delves into Belyaev’s radical ideas on self-domestication – ideas that he first raised at the Moscow International Genetics Congress- including the possibility that we humans have self-domesticated ourselves. Readers will learn these ideas are now being tested in chimpanzees, bonobos and Homo sapiens. Belyaev never lived to see that, though, as our chapter ends with his untimely death in 1985.


DOI: 10.7208/chicago/9780226444215.003.0008
[Collapse of USSR;foxes in trouble;SOS article;molecular genetics]
Chapter 8 sees the Soviet Union collapsing, funds for the fox work being severely slashed, and when the ruble collapses in 1998, money for the experiment all but drying up. Lyudmila and her team have stashed away some money over the years, and they are chipping in their own personal funds too, but the situation, in terms of food and vaccines for the foxes, is grim. At one point, they go out onto the roads around the farm and the Institute of Cytology and Genetics, stopping cars, asking people for money or any kind of food at all that they can give. The situation improves after Lyudmila pens an SOS article for The American Scientist, telling readers “For the first time in 40 years, the future of our domestication experiment is in doubt.” Readers send in money, and scientists who read the article, approach Lyudmila about collaborations. One such collaboration begins when Anna Kukekova, a molecular geneticist who worked on dogs, joins with Lyudmila to look at the molecular genetic underpinnings of domestication in the foxes.


DOI: 10.7208/chicago/9780226444215.003.0009
[social cognition;human-like laughs in foxes;molecular genetics]
Chapter 9 opens as the new millennium begins and the fox domestication experiment is back on its feet again. Lyudmila and Anna continue their work on molecular genetic changes in the domesticated foxes. At the same as this work is underway, Lyudmila, together with an American researcher named Brain Hare, are studying social cognition in the domesticated foxes, and Lyudmila joins with a Russian colleague, Svetlana Gogolova, in uncovering human laugh-like vocalizations that the tame foxes, and only the tame foxes, make.


DOI: 10.7208/chicago/9780226444215.003.0010
[tame foxes as pets;gene expression;Lyudmila still at the helm]
Chapter 10 shows readers that work on the molecular genetics of domestication in the foxes continues to this day, and though many questions remain unanswered, this work is shedding light on both the location of key genes, as well as the role that changes in gene expression play in the process of domestication. While that work progresses, more and more changes are also occurring in the behavior and morphology of the tame foxes, and like they have every day for almost six decades, Lyudmila and her colleagues are recording and analyzing these changes to better understand the process of domestication. Lyudmila recognizes that the foxes are now animals that we humans can take into our lives and love. “Dainty, fluffy, charming rogues” is how she now describes them. In 2010, Lyudmila starts to seriously explore whether people want to purchase tame foxes as pets. In 2016, having celebrated her 83rd birthday, Lyudmila still works with the foxes every day. “I hope that it is possible to register them as a new pet species,” she says. “One day I will be gone, but I want my foxes to live forever.”
