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.

A scientist explores the harmony between Christian faith and science Though some Christians and many skeptics see science and Christianity as locked in a never-ending battle, geologist Gregg Davidson contends that there is tremendous harmony between Scripture and modern science. Many apparent conflicts arise when the Bible is interpreted apart from its literary and historical contexts, but when these are taken into account, most alleged clashes resolve. Proceeding from a belief that Scripture is inspired and without error and that God's creation should inform how we interpret the Bible, Davidson shows that Scripture and science need not disagree on issues like the age of the earth, Adam and Eve, Noah's flood, the origin and development of life, and numerous related topics. Rather, Christians can rejoice at how God's glory is revealed in both the Bible and the natural world.

A wide-ranging argument by a renowned anthropologist that the capacity to believe is what makes us human Why are so many humans religious? Why do we daydream, imagine, and hope? Philosophers, theologians, social scientists, and historians have offered explanations for centuries, but their accounts often ignore or even avoid human evolution. Evolutionary scientists answer with proposals for why ritual, religion, and faith make sense as adaptations to past challenges or as by-products of our hyper-complex cognitive capacities. But what if the focus on religion is too narrow? Renowned anthropologist Agustín Fuentes argues that the capacity to be religious is actually a small part of a larger and deeper human capacity to believe. Why believe in religion, economies, love? A fascinating intervention into some of the most common misconceptions about human nature, this book employs evolutionary, neurobiological, and anthropological evidence to argue that belief—the ability to commit passionately and wholeheartedly to an idea—is central to the human way of being in the world.

“Lively and fascinating... The reader comes away cheered, better informed, and with a new and deeper appreciation for our amazing canine companions and their enormous capacity for love.”—Cat Warren, New York Times best-selling author of What the Dog Knows Does your dog love you? Every dog lover knows the feeling. The nuzzle of a dog’s nose, the warmth of them lying at our feet, even their whining when they want to get up on the bed. It really seems like our dogs love us, too. But for years, scientists have resisted that conclusion, warning against anthropomorphizing our pets. Enter Clive Wynne, a pioneering canine behaviorist whose research is helping to usher in a new era: one in which love, not intelligence or submissiveness, is at the heart of the human-canine relationship. Drawing on cutting‐edge studies from his lab and others around the world, Wynne shows that affection is the very essence of dogs, from their faces and tails to their brains, hormones, even DNA. This scientific revolution is revealing more about dogs’ unique origins, behavior, needs, and hidden depths than we ever imagined possible. A humane, illuminating book, Dog Is Love is essential reading for anyone who has ever loved a dog—and experienced the wonder of being loved back.

A dazzling tour of evolution in action that sheds light on one of the greatest debates in science The natural world is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. Convergence suggests that evolution is predictable, and if we could replay the tape of life, we would get the same outcome. But there are also many examples of contingency, cases where the tiniest change - a random mutation or an ancient butterfly sneeze - caused evolution to take a completely different course. So are we humans, and all the plants and animals in the world today, inevitabilities or evolutionary freaks? What role does chance play in evolution? And what could it tell us about life on other planets? In Improbable Destinies, renowned researcher Jonathan Losos reveals what the latest breakthroughs in evolutionary biology tell us about one of the greatest ongoing debates in science. Evolution can occur far more rapidly than Darwin expected, which has opened the door to something that was previously thought impossible: experimental studies of evolution in nature. Drawing on his own work with anole lizards on the Caribbean islands, as well as studies of guppies, foxes, field mice and others being conducted around the world, Losos reveals just how rapid and predictable evolution can be. By charting the discoveries of the scientists who are rewriting our understanding of evolutionary biology, Improbable Destinies will change the way we think and talk about evolution.
